Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: Lunar Prospector Update - April 1, 1998 Привет всем! Вот, свалилось из Internet... Lunar Prospector Status Report #27 April 1, 1998 7:00 p.m. EST (4:00 p.m. PST) The Lunar Prospector spacecraft continues to perform very well, and all instruments continue to collect good data, according to Mission Control at NASA's Ames Research Center. On Tues., March 31 (PST), mission controllers executed an attitude reorientation trim maneuver. In doing so, the spacecraft's spin axis was reoriented about 5 degrees so that the Sun shines on the top half of the spacecraft. The maneuver required 23 pulses, as detailed by the timeline below: Tues., March 31, 2:32 p.m. (PST) Thruster heaters on Tues., March 31, 2:37 p.m. (PST) Maneuver parameters loaded Tues., March 31, 2:58 p.m. (PST) Thrusters A1 and A4 fired (23 pulses) to rotate spin axis 4.7 degrees Tues., March 31, 3:01 p.m. (PST) Thruster parameters reset The Lunar Prospector engineering team is still investigating the results of the spin axis reorientation by reviewing pre-and post-maneuver attitude data. Calibration data for the Earth-Moon Limb Crossing Sensor requires updating based upon flight data. Until this recalibration is complete, the precise attitude and performance of the maneuvers cannot be analyzed. The current state of the vehicle (as of 4:00 p.m. (PST) on Wed., April 1, 1998), according to Mission Operations Manager Marcie Smith, is as follows: Spacecraft Orbit Number: 968 Data Downlink Rate: 3600 bps Spin Rate: 11.96 rpm Spin Axis Attitude Longitude: (see above) Latitude: (see above) Trajectory Periselene: 93.4 km Aposelene: 105.9 km Period: 118 minutes Inclination: 90.2 degrees Occultations: 25 minutes in duration Eclipses: 47 minutes in duration (maximum) At present, Lunar Prospector is aligned with the Moon-Sun line. This means that the spacecraft passes directly over the local noon and midnight points on the Moon, experiencing the hottest temperatures and longest eclipses of the entire mission. In about three months, when the Earth (and thus the Moon) have continued around the Sun, the spacecraft's orbit plane will be perpendicular to the Moon-Sun line, and there will be a period of a few weeks with no eclipses before the next eclipse season begins.

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: NASA Joins In Apple Valley Science and Technology Center Dedication Привет всем! Вот, свалилось из Internet... MEDIA RELATIONS OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIF. 91109 TELEPHONE (818) 354-5011 http://www.jpl.nasa.gov Contact: John G. Watson April 3, 1998 NASA JOINS IN APPLE VALLEY SCIENCE AND TECHNOLOGY CENTER DEDICATION NASA has assisted in recycling an old space communications and tracking antenna into a radio telescope for the use of students and teachers around the nation. The telescope is controlled through a new NASA-supported facility to improve and expand science and technology education, dedicated today in Southern California's Apple Valley. The Apple Valley Science and Technology Center, renamed the Lewis Center for Education Research in honor of supporter U.S. Representative Jerry Lewis, features an innovative Internet- linked system that allows students across the country to remotely control the resurrected NASA space communications antenna to conduct radio astronomy experiments. Among those scheduled to participate in the ceremonies today were Mrs. Gayle Wilson, wife of Governor Pete Wilson of California; NASA Administrator Daniel Goldin; NASA Jet Propulsion Laboratory (JPL) Director Dr. Edward C. Stone; retired NASA astronaut Dick Covey; and Congressman Jerry Lewis. Staffed by a small professional staff and hundreds of volunteers, the Lewis Center for Education Research is a hub of learning for students of all ages interested in meteorology, astronomy, environmental studies and aviation, among many other subjects. In 1996, the center took over operation of a nine-story-high tracking antenna within the Goldstone site of NASA's Deep Space Network, near Barstow, CA. Instead of tearing down the decommissioned antenna, JPL entered into an agreement allowing the center and the school district to operate the antenna as a radio telescope for use via the Internet by students from around the United States. NASA and JPL staff and volunteers participated in converting the antenna into a radio telescope and linking its control system to classrooms via the Internet. Goldin, Lewis, Stone and Wilson were scheduled to staff the center's mission control today to join students in Michigan and Kentucky as they operated the giant radio telescope from their classrooms. The original Science and Technology Center, built nearly 10 years ago, now houses an observatory, Air Force jet flight simulator, computer center, weather station and related hands-on learning tools for students. It has drawn more than 80,000 students and teachers from across the nation. The center, affiliated with the Apple Valley Unified School District, has drawn the support of many business and community leaders from its inception in 1985 for its effective experiments with new, creative educational methods. In 1997, the center was awarded a federal grant to expand its facilities. In addition to adding offices, the new facility offers several innovative new educational spaces, including mission control, a high-tech control room where students from around the world are able to control the decommissioned Deep Space Network antenna. A digital TV studio, amateur radio station and control room were built with support from NASA and the Desert Community Bank and will allow students to produce and broadcast educational programs to more than 35,000 homes in cooperation with Hi-Desert Cablevision. The facility also features a library, sponsored by the Assistance League of the Victory Valley; and a Gateway to Excellence technology classroom sponsored by GTE, which includes a science education laboratory with a climate-controlled greenhouse. The center also operates the Academy for Academic Excellence, a K-12 California Public Charter School, chartered by the Apple Valley Science and Technology Center. It combines classroom and lab work at the center with parental schooling in an innovative program to explore new effective learning programs. Classes are offered at the center for both students and parents. JPL is a division of the California Institute of Technology, Pasadena, CA. -end- NOTE TO BROADCASTERS: NASA TV will air a video file about the center throughout the day on April 3.

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: Cassini Update - April 3, 1998 Привет всем! Вот, свалилось из Internet... CASSINI SIGNIFICANT EVENTS FOR WEEK ENDING 04/03/98 Spacecraft Status: The Cassini spacecraft is presently traveling at a speed of approximately 143,000 kilometers/hour (~89,000 mph) relative to the sun and has traveled approximately 464 million kilometers (~288 million miles) since launch on October 15, 1997. The most recent Spacecraft status is from the DSN tracking pass on Thursday, 04/02, over Canberra. The Cassini spacecraft is in an excellent state of health and is executing the C7 sequence nominally. Inertial attitude control is being maintained using the spacecraft's hydrazine thrusters (RCS system). The spacecraft continues to fly in a High Gain Antenna-to-Sun attitude. It will maintain the HGA-to-Sun attitude, except for planned trajectory correction maneuvers, for the first 14 months of flight. Communication with Earth during early cruise is via one of the spacecraft's two low-gain antennas; the antenna selected depends on the relative geometry of the Sun, Earth and the spacecraft. The downlink telemetry rate is presently 40 bps except for the probe checkout playbacks at 948 bps which are done over specially-requested 70m DSN passes. Spacecraft Activity Summary: Orbiter: From Friday, 03/27, through Monday, 03/30, there were no changes in spacecraft configuration. On Tuesday, 03/31, the first of seven data playbacks occurred for Huygens Probe Checkout #2. The Probe checkout activity occurs approximately every 6 months. The series of data playbacks from the SSR will provide detailed information on the results of the checkout. On Wednesday, 04/02, the Solid State Recorder (SSR) record and playback pointers were reset, according to plan. This housekeeping activity, done approximately weekly, maximizes the amount of time that recorded engineering data is available for playback to the ground should an anomaly occur on the spacecraft. Also on Wednesday, the now standard SSR Flight Software Partition maintenance activity was performed. This activity repairs any SSR double bit errors (DBEs) which have occurred in the code-containing portions of the Flight Software partitions during the preceding period. Finally, on Wednesday, the second data playback occurred for Probe Checkout #2. On Thursday, 04/02, the spacecraft was commanded back to the state in which the A unit of the Probe Support Avionics (PSA) is identified as prime. At the termination of each Probe checkout activity, the spacecraft switches to the B unit of the PSA. The commanding to reset the PSA to the A unit is a standard post-checkout housekeeping activity which establishes the desired hardware state for the next Probe checkout. Upcoming events: Activities scheduled for the week of 4/03 - 4/09 include: the remaining 5 (of 7) Probe Checkout data playbacks (4/03 through 4/07), and an SSR pointer reset (4/06). Probe: Huygens: Second In-Flight Checkout ESA reports that a first look at the (Probe Checkout #2) data indicates that their overall quality is good and that in most respects the Probe behaved as expected. However, the AGC (Automatic Gain Control) telemetry measurements on both chains seems to have dropped further (by 3 to 4 dB), with respect to the values of the first in-flight checkout. The AGC level is a measurement in the umbilical (mated) configuration. ESA has formed an investigation team to understand these telemetry measurements. DSN Coverage: Over the past week Cassini had 10 scheduled DSN tracks occurring from 03/27 through 4/02. In the coming week there will be 9 DSN passes. Other Program Activities On Friday, 3/27, the Program determined that because of navigation accuracy, that no trim maneuver is required for the final leg of the mission's first Venus gravity assist swingby, planned for April 26, 1998.

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: Sky & Telescope News Bulletin - April 3, 1998 Привет всем! Вот, свалилось из Internet... SKY & TELESCOPE'S NEWS BULLETIN APRIL 3, 1998 THE YOUNGEST PLANETARY NEBULA Astronomers say that a picture taken by the Hubble Space Telescope's Wide Field and Planetary Camera 2 shows the youngest planetary nebula yet imaged. Dubbed the Stingray Nebula (Hen 1357), the sphere of glowing gas lies about 18,000 light-years away in the southern hemisphere constellation Ara. The nebula is some 130 times the size of our solar system, but this is only about one-tenth the size of other known planetary nebulae. Hubble has been the first telescope to provide a close look at this small nebula. Amid the complex structure that includes a ring and bubbles of gas, the image reveals that the central star is binary. Recently, astronomers have suggested that the presence of a companion is key in the creation of varied shapes of planetary nebulae. A "PERFECT" EINSTEIN RING Another Hubble image -- coupled with radio observations -- show for the first time a complete "Einstein ring." This phenomenon arises when the light from a background galaxy is bent around a foreground object by gravitational lensing. A precise lineup is required to form a complete circular "mirage" around the intervening galaxy. British researchers announced the finding at this past week's UK National Astronomy Meeting at the University of St. Andrews. They note that they used Hubble imagery and data from the UK's 200-kilometer-wide MERLIN radio array to capture the remarkable sight. The Einstein ring is only about 1 arcsecond across. Results will be published in the April 1st Monthly Notices of the Royal Astronomical Society. JUPITER'S NEW DUST RING For a ring of another sort, astronomers have found evidence for a previously unknown 1.1-million-km-wide ring of dust around Jupiter. Joshua Colwell (University of Colorado at Boulder) and his colleagues used data from dust detectors aboard the Galileo spacecraft to determine the quantity and motions of the particles. Computer models showed they the material formed a torus or doughnut shape. Perhaps the most curious aspect of the dust particles is that they orbit the planet "retrograde," or the reverse way from the other moons of Jupiter's satellite system. Details of the study appear the April 3th issue of Science. MILKY WAY SHRINKS According to two University of Southampton astronomers, the Milky Way galaxy isn't as big as previously thought. Michael Merrifield and Robert Olling examined studies of the motions of stars and conclude that the Sun is located some 23,000 light-years from the center of the galaxy, and moving at about 185 km per second. These values are at the lower ends of the range of estimates from various studies. Such galactic depreciation could have wider consequences in the sizing of the universe. SUPERNOVA SHINES ON Amateurs continue to follow the supernova discovered on March 2nd in the galaxy NGC 3877 in Ursa Major. Supernova 1998S, an unusual Type IIn supernova, has been holding steady at 12th magnitude. The 11th-magnitude galaxy is located just 0.3 degree due south of the star Chi Ursae Majoris. Supernova 1998S is 14" west and 46" south of the elongated galaxy's center. Observers report that the supernova is easier to see than the galaxy itself. THIS WEEK'S "SKY AT A GLANCE" Some daily events in the changing sky, from the editors of SKY & TELESCOPE. APRIL 5 -- SUNDAY * Daylight saving time begins at 2 a.m. for most of the United States. Turn clocks ahead one hour. APRIL 6 -- MONDAY * Regulus shines to the left of the Moon this evening. * Mercury is at inferior conjunction, nearly in front of the Sun and therefore hidden from sight in the Sun's glare. APRIL 7 -- TUESDAY * The eclipsing variable star Algol is getting low in the northwest after dusk. It should be at minimum light, magnitude 3.4 instead of its usual 2.1, for a couple hours centered on 11:38 p.m. EDT (8:38 p.m. PDT). Algol takes several hours before and after to fade and rebrighten. APRIL 8 -- WEDNESDAY * Some doorstep astronomy: The brightest star due east these evenings is Arcturus. Far to its upper left is the Big Dipper, which is tipping leftward on its handle. APRIL 9 -- THURSDAY * More doorstep astronomy: Look southwest at dusk for Sirius, the brightest star in the sky. High above it is Procyon. A similar distance to the right or upper right of Sirius is the constellation Orion. APRIL 10 -- FRIDAY * Algol is at minimum light for a couple hours centered on 8:27 p.m. EDT. APRIL 11 -- SATURDAY * Full Moon (exact at 6:23 p.m. EDT). Spica is to the Moon's lower right. ============================ THIS WEEK'S PLANET ROUNDUP ============================ MERCURY, MARS, and SATURN are hidden in the glare of the Sun. VENUS shines brightly low in the east-southeast during dawn. JUPITER is far to the lower left of Venus. URANUS and NEPTUNE, magnitudes 6 and 8, respectively, are in Capricornus low in the southeast just before dawn. PLUTO, magnitude 13.8, is near the Ophiuchus-Scorpius border. It's well up in the southeast by 1 a.m. (All descriptions that relate to the horizon or zenith are written for the world's midnorthern latitudes. Descriptions that also depend on longitude are for North America. Eastern Daylight Time, EDT, equals Universal Time minus 4 hours.)

MEDIA RELATIONS OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIF. 91109 TELEPHONE (818) 354-5011 http://www.jpl.nasa.gov Cassini Mission Status April 3, 1998 The Cassini spacecraft remains on track for its flyby of Venus on April 26, which due to the effects of Venus' gravity, will give the spacecraft a 26,280 kilometer-per-hour boost (16,330 mile-per-hour) in speed. Cassini's navigators have determined that the spacecraft is already so accurately targeted for its 284-kilometer altitude swingby of Venus that a scheduled fine-tuning maneuver is unnecessary and has been cancelled. Cassini is feeling the Sun's gravitational tug since the spacecraft last week reached its perihelion, or closest point to the Sun, and is now flying in outbound direction. The spacecraft is traveling at a speed of approximately 143,000 kilometers per hour (about 89,000 miles per hour) relative to the Sun, and has traveled approximately 464 million kilometers (about 288 million miles) since launch on October 15, 1997. Over the past week, Cassini began transmitting previously recorded data from last week's engineering checkout of the European Space Agency's Huygens probe. This health-check of Huygens occurs every six months. The data are forwarded to the Huygens team in Europe for analysis. The remainder of the engineering checkout data from Huygens is scheduled to be transmitted from the spacecraft next week. ##### Hа сегодня все, пока! =SANA=

The upgrade will consist of replacing the battery and control boards, and install circuitry that will allow the satellite to make voice announcements in French, Russian, and English. [Info via Miles Mann, WF1F] * OSCAR-11 UPDATE * After ground control operations that took place during the third week of March, the 145.826 MHz VHF-FM beacon is now transmitting normally. Strong signals have been received from UoSAT-OSCAR-11. Telemetry shows that the S-band beacon is ON. Telemetry also indicates that there is a reduction in the 14 volt line current of about 50 mA and a reduction in the +5 volt current of about 25 mA. The reason for these changes is not widely known. A new WOD survey of channels 1, 2, 3, 61 (magnetometers) dated 19-Mar-98 has been started. Anyone using this survey should note the unusual starting time of 16:00:05 UTC. [Info via Clive Wallis, G3CWV] * TECHSAT LAUNCH NEWS * Speaking on behalf of AMSAT, Shlomo Menuhin 4X1AS announced that at long last (barring any major difficulties) the Israeli Amateur Radio TECHSAT II produced at the Technion University in Haifa will be launched in late April or early May 1998. The satellite will sport a packet radio store and forward mailbox operating at 9600 baud. The satellite will be launched from Kazakhstan, and Shlomo will be on hand to represent AMSAT.

The filter will be used to prevent interference from a commercial VHF-FM transmitter on-board Mir from affecting the sensitivity and performance of the 2-meter packet radio station on-board Mir. The MIREX-DCI filer is a custom designed antenna cavity filter that will block the offending signal with a combination of passband and notch filters. The filter system is tentatively planned for installation in the April/May time frame. The MIREX team would like to thank all of the supporters of the filter project, including DCI Digital Communications, Inc, SAFEX, and the SAREX Working Group.

SB NEWS @ AMSAT $SPC0406 * SpaceNews 06-Apr-98 * BID: $SPC0406 ========= SpaceNews ========= MONDAY APRIL 6, 1998 SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is published every week and is made available for non-commercial use. * MIREX SCHOOL DAY TEST PLANNED * To permit maximum participation by schools and students in a joint MIR communicatons experiment, the MIREX team has authorized a special MIREX School Day test on April 27th 1998 between 1000 and 2300 UTC. The purpose of the test is to improve the understanding of students about the Space Station and demonstrate the factors involved in space communications using amateur radio. Of the many schools to participate, even schools for the deaf and disabled will be able to experience the event through their computer displays. There is no limit to the number of stations that can participate, since any amateur radio station at any school in the world may monitor the downlink of the test. All stations will be able to capture and log communications from both MIR itself and the other schools authorized to transmit. Due to the limited capacity on the uplink, however, the number of stations authorized to transmit will be limited to under 100 per footprint area. In general, only schools and other youth group demonstrations will be authorized to transmit. For planning purposes, schools intending to transmit should send Email to wb4apr@amsat.org including the following brief information: 1) Callsign and Point of contact 2) School Name or affiliation 3) Number of students that might participate 4) Equipment used at the School (power and antenna type) After the test, the MIREX team would like to hear about any media coverage or any interesting observations or special events at your site. To allow the maximum probability of success on each orbit, schools will transmit via UI frames and the experiment will proceed in phases. As each phase is successfully accomplished, then additional complexity may be added to the experiment. This phased approach makes sure that everyone gets an equal chance of success without congestion while allowing for additional capacity if it exists. The MIR packet system will downlink a brief BULLETIN once every 3 minutes. Each school should expect to capture these bulletins at some time during the pass. Concurent with the Bulletin Phase, the next objective is for each transmitting school to successfully relay a position/status report via MIR and for all other schools to receive them. A position packet will look something like this: W3ADO>GGggGG,R0MIR*:]k[ US Naval Academy. 75 Students 35w. Hi MIR! Here, the GGggGG is the stations grid square which is sufficient to locate the school to within about 3 miles. The ]k[ is the map ICON for a school. Stations may transmit these single packets at about a one-a-minute rate until successful. Once they see their position in the downlink, then they should stop sending their position. After each school has captured one full page of position packets (16 stations) from other schools, indicating others are being successful and their station is hearing the downlink, then the authorized schools may send a single message packet to any other station. For each additional page of 16 positions that each school captures, it may send additional packets up to a maximum of 5. A special version of packet software called MIRMON has been donated for unlimited use during this experiment. MIRMON will capture all position reports, bulletins and messages and give schools a consistent display of the event. The software may be downloaded and further test details as well as a replay of the last such experiment are available on the Naval Academy MIREX WEB page at the following URL: http://web.usna.navy.mil/~bruninga/mirex.html Schools with at least a 2m FM 25 watt transceiver, an omni-directional antenna, and a conventional TNC should be successful. Individual hams wishing to participate are welcome to monitor the test in RECEIVE ONLY, or to visit a school and set up a demonstration to qualify to transmit. This means all stations should be manned and not operated unattended. Even schools without current ham radio equipment can monitor the event via the live Web pages above and also at www.mirex.net. The MIREX Team is trying to find dedicated ground stations, at least one per continent, that can link their receiver to a growing MIREX network. Currently there are feeds in the Eastern USA, Mexico, and Spain under construction. To see the combined feed from these stations, browse the web site above or telnet to www.mirex.net. For school info contact Bob at: wb4apr@amsat.org. [Info via Dr. Dave Larsen, N6CO -- MIREX President] * FUJI-OSCAR-29 NEWS * On a pass at 0800 UTC on 27-Mar-98, the FO-29 spacecraft command station detected two bit errors in the satellite's On Board Computer (OBC) while attempts were made to switch the satellite into mode JD 1200. Resetting the computer and reloading software will take a while, so the satellite will remain in Mode JA until further notice.

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: Dust Ring Discovered Around Jupiter Привет всем! Вот, свалилось из Internet... MEDIA RELATIONS OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIF. 91109 TELEPHONE (818) 354-5011 http://www.jpl.nasa.gov Contact: Jane Platt April 3, 1998 FOR IMMEDIATE RELEASE: NEW CLASS OF DUST RING DISCOVERED AROUND JUPITER Scientists have found evidence for a new ring of dust that occupies a backward orbit around Jupiter, based on computer simulations and data from NASA's Galileo spacecraft, it is reported in today's issue of Science magazine. A team led by researchers at the University of Colorado at Boulder reported that a faint, doughnut-shaped ring of interplanetary and interstellar dust some 1,126,000 kilometers in diameter (about 700,000 miles) appears to be orbiting the giant planet. Evidence for the new ring's existence comes from computer simulations that correlate with data collected by a dust detector aboard the Galileo spacecraft has detected this ring by capturing some of its dust, said Dr. Joshua Colwell, a research associate at the university's Laboratory for Atmospheric and Space Physics. Surprisingly, the researchers say, most of the interstellar and interplanetary dust particles appear to be in a "retrograde" orbit -- that is, moving in the opposite direction of the rotating planet and its moons, Colwell said. The reason for the backward orbit of the tiny particles is not yet clear, he said. The paper in Science magazine was authored by Colwell, research associate Dr. Mihaly Horanyi, also of the Laboratory for Atmospheric and Space Physics, and planetary scientist Dr. Eberhard Grun of the Max Planck Institute for Astrophysics in Heidelberg, Germany, who is the principal investigator on Galileo's dust detector. The Galileo mission is managed by NASA's Jet Propulsion Laboratory (JPL), Pasadena, CA. JPL is a division of the California Institute of Technology, Pasadena, CA. NASA's Voyager 2 detected an uneven dust ring around Jupiter in 1979 that scientists believe was created by the collisions of small moonlets with micrometeoroids in the Jovian system. But the newly identified ring of dust with smoke-size particles originating from beyond the Jovian system appears to be much larger, more sparse and, possibly unique in the solar system. "I suspect we may wind up seeing something similar at Saturn," said Colwell. Launched in 1997, NASA's Cassini spacecraft will reach the ringed planet in 2004. ##### Hа сегодня все, пока! =SANA=

The report, according to the Monday, March 23 issue of the Wall Street Journal, estimates that the total cost of the station could go as high as $24 billion. Earlier this month, NASA Administrator Dan Goldin estimated the total cost of the station at $20.6 billion, about $3 billion more than 1993 estimates. The report places the blame on the overruns on "overly optimistic" cost estimates by NASA and Boeing, the prime contractor for the International Space station; Russian delays; the addition of new equipment like the X-38 crew return vehicle; and too-low spending caps set by Congress in 1993. "Hopefully, Congress is going to accept this as the realistic estimate," Jay Chabrow, chair of the independent panel, told Florida Today. "They can either give NASA what they need or they can come up with some political polemic which has nothing to do with the facts." At least one member of Congress is planning action based on the report. "This thing is continuing to spiral out of control," Sen. John McCain (R-AZ), chair of the Senate Commerce Committee, told the Wall Street Journal. "There may be a requirement for some kind of restructuring. We just can't keep up." McCain told the Journal that he plans to hold hearings on the report in the near future. Some members of Congress, however, challenged Chabow's assertion that the fault for the cost caps should be placed on Congress. McCain and House Science Committee head James Sensenbrenner (R-WI) issued a joint press release March 27, pointing out that the $2.1 billion a year cost cap was chosen by President Clinton in 1993. "We have repeatedly expressed concern about the escalating cost overruns for the Space Station," McCain said. "It is unconscionable that now NASA is trying to blame us for its problems of mismanagement and poor planning." A NASA spokesman told Florida Today that they would withhold comment on the report until they received and reviewed a copy of the report. Hа сегодня все, пока! =SANA=

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: SpaceViews - April 1998 [2/17] Привет всем! Вот, свалилось из Internet... Space Tourism Report Released A report by NASA and a private group, released Wednesday, March 25, concluded that "serious national attention" by government, aerospace companies, and tourism companies, should be given to promoting space tourism. The "General Public Space Travel and Tourism" report by NASA and the Space Transportation Association was released at a press conference March 25 that featured the authors of the study as well as three members of Congress. The report was the cumulation of two years of study, which included a conference on space tourism last year. "This study concludes that serious national attention should now be given to activities that would enable the expansion of today's terrestrial space tourism businesses, and the creation of in-space travel and tourism businesses," the summary of the report stated. The reported noted that the current market for space tourism is small because of the high cost of space access, but that the market could grow dramatically as cheap access to space becomes viable. The study stated that improvements in technology and operations should allow passenger prices to fall to at least $50,000, and perhaps $10,000 to $20,000, ten years from now. At a per-ticket price of $50,000, "it is believed that there could be [on] the order of 500,000 space trip passengers/year," the report concluded. Transporting that many people to and from orbit would require roughly 1,000 times the current annual American space payload, the report concluded, but would still be far less than commercial airline traffic. The report made a number of recommendations to further space tourism. The study authors called on NASA to continue research in reduced launch costs, and also suggested that the space shuttle and International Space Station be used for "public tourist R &;D [research and development] and initial 'demonstration' merchandising activities." The report also called on a number of private companies, from aerospace firms to cruise lines, hotels, and adventure tour operators, to consider the possibilities of space tourism. The report suggested the use of lotteries and auctions for early space tourism programs so that they are "conducted in an egalitarian fashion" and paid for with private funds. The report got a positive response from space activists. "It is clear with the release of today's study that the question to ask about developing a space tourism industry is no longer 'can it ever happen,' but rather 'how long until it does,'" Pat Dasch, executive director of the National Space Society, said. Commenting on the presence of the Congressmen, including Rep. Dana Rohrabacher (R-CA), chair of the space subcommittee of the House Science Committee, Dasch noted, "To hear our elected officials recognize and articulate the value of space tourism as an industry is encouraging. We heartily agree with Mr. Rohrabacher's assessment of that value as 'permitting the dreamers to participate personally.'" New Evidence for Past Mars Life Scientists have found new evidence that a meteorite from Mars does contain evidence of ancient primitive life on the Red Planet, the Boston Globe reported Saturday, March 21. At the annual Lunar and Planetary Sciences Conference in Houston Friday, March 20, scientists announced that meteorite ALH 84001, in which a NASA-academia team first reported evidence for past life in 1996, contains a mineral in a crystal form only produced on Earth by organisms. The new research, performed by some of the same scientists who were involved with the 1996 announcement, studied a crystalline form of magnetite, a magnetic mineral that can be produced both by basic chemical processes and by living organisms on Earth. However, the crystals of magnetite seen within ALH 84001 have the same unusual hexagonal form seen in those created only by terrestrial microbes. "We don't know of any nonbiological process" than could produce the crystals, the Globe quoted Kathie Thomas-Keprta as saying. Thomas-Keprta reported the new findings Friday and was also one of the researchers in the original Mars life analysis. David McKay, the Johnson Space Center scientist who was the lead author of the original Mars life paper, called the new findings "our strongest evidence" for past life on Mars, he told the Globe. Another presentation disputed recent claims that the meteorite was contaminated by organic compounds in the Antarctic ice is landed in over 10,000 years ago. Simon Clemett of Stanford University reported that some compounds found in the meteorite are very different that organic compounds found in the ice, making it possible to distinguish between terrestrial contamination and Martian organic material. Two studies published in January claimed the meteorite had been contaminated by terrestrial organic materials, putting in doubt one of the key pieces of evidence for life from the meteorite, the discovery of organic compounds possibly formed by living organisms on Mars.

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: SpaceViews - April 1998 [3/17] Привет всем! Вот, свалилось из Internet... Astronauts Discuss Life on Mir The current astronaut on the space station Mir described life on the space station during a live Webcast March 23, while a former Mir astronaut spoke out about conditions on the station a few days later. Andy Thomas, who has spent two months on Mir, spoke for twenty minutes with actor Alan Alda March 23 in an interview that was broadcast live on the Internet. Alda, host of the PBS series "Scientific American Frontiers", interviewed Thomas for a future episode. In the interview, Thomas said he had adapted quite well to life on the station. Noting that life in weightless in a cramped space station is a "completely unnatural state", he noted that at first "I thought I would never adapt." However, Thomas said he quickly adjusted to life on Mir. "It's amazing how quickly it's become the natural state of things," he said. "It's one of the biggest challenges I've had, and certainly one of the most rewarding." A few days later, former astronaut Jerry Linenger, who spent four months on Mir a year ago, told the Orlando Sentinel that the time had come to retire the aging station. "You need to know when somebody's ready to retire and retire with dignity," he said. Linenger described a brief but harrowing fire on the station in February 1997, when at times it appeared uncertain that the crew would be able to escape alive. He said the smoke was so thick he could not see his hand in front of his face, and had problems finding a working air mask. Linenger also described communications problems between the ground and Mir, including the inability to get regular e-mail messages. Andy Thomas has experienced similar problems while on Mir, as Russian officials have refused to radio e-mail messages for Thomas to Mir. Life on Mir continues to be fairly normal. On April 1 the two Russian cosmonauts on Mir, Talgat Musabayev and Nikolai Budarin, began a series of five spacewalks scheduled for the next three weeks to make repairs outside the station. The April 1 spacewalk was to stabilize a bent solar panel on the damaged Spektr module. However, delays in setting up the equipment needed for the repair, including mounting handholds and footrails, have delayed the repairs until an April 6 spacewalk. NASA Plans "Face on Mars" Images NASA announced Thursday, March 26, plans to return images next month from the Mars Global Surveyor (MGS) spacecraft of specific regions on the Red Planet, including the infamous "Face on Mars" feature which some claim to be an artifact made by an extraterrestrial intelligence. The imaging of the Martian surface will begin on March 27, shortly after the spacecraft suspends its aerobraking procedure. NASA plans to image certain areas of interest on the planet, including spacecraft landing sites and the Cydonia region, where the Face is located, in the first month after aerobraking. "Global Surveyor will have three opportunities in the next month to see each of the sites," said MGS project manager Glenn Cunningham. "The sites will be visible about once every eight days, and we'll have a 30- to- 50-percent chance of capturing images of the sites each time." The reason the odds of capturing images of the sites is low is from uncertainties in the spacecraft position and the direction its camera is pointing. Moreover, previous MGS observations showed that errors of up to 1 to 2 km (0.6 to 1.2 mi.) in the location of objects exist in maps made of the surface from Viking spacecraft images in the 1970s. NASA is taking great steps to show that the Face, seen in Viking data and interpreted by some as a relic from a past Martian civilization, is nothing more than a natural phenomenon. Carl Pilcher, acting space science director at NASA headquarters, said most scientists agree the Face is natural, but, "we also believe it is appropriate to seek to resolve speculation about features in the Cydonia region by obtaining images when it is possible to do so." A small but vocal group of people have claimed the feature was artificial, and possibly an alien artifact, and have claimed that NASA has withheld evidence about the face and obstructed plans for future observations. Those people include Richard Hoagland, author of the book "The Monuments of Mars" NASA also announced plans to image the landing sites of the two Viking landers and Mars Pathfinder. Scientists will combine the images with the data collected by the landers to provide some "ground truth" to tie the two sets of observations together. An exact timetable of the observations, and schedule of release of images from those observations, was announced as the orbit was finalized. The first Cydonia mapping attempt will be on April 5. MGS will collect images and other data about Mars during a nearly six-month break in the aerobraking process. The extended aerobraking process was dictated by the bending of a solar panel which did not properly lock into position after launch in 1996. Aerobraking will resume in September and finish in March 1999, when the spacecraft is placed in its final mapping orbit. Busy International Launch Schedule The latter half of March was marked by a series of Russian, Chinese, European, and American launches of satellites, from Mir cargo to more Iridium satellites. A Russian Progress spacecraft was launched March 15, and docked with the station two days later. The spacecraft carried food and other supplies for the station, including new wrenches to replace ones broken during an aborted March 4 spacewalk effort. Progress also carried a new attitude control thruster module that will be mounted outside the station later this month. An Atlas II booster launched a Navy communications satellite from Cape Canaveral March 16. The Navy Ultra High Frequency (UHF) Follow-On F8 satellite is the first of three new geosynchronous communications satellites the Navy will use to broadcast messages to new mobile receivers. An Ariane 4 booster launched the SPOT 4 remote sensing satellite Monday evening, March 23, from Kourou, French Guiana. The satellite, funded largely by the French space agency CNES, will spend five years in a Sun-synchronous orbit using instruments that include a multispectral camera and a visible/infrared camera optimized for studying vegetation. Two launches in late March placed seven more Iridium satellites into orbit. A Chinese Long March 2C launched two satellites from the Taiyuan launch site March 25, while a Delta II placed five more in orbit March 30 from Vandenberg Air Force Base. The Delta II launch had been delayed a week by high winds. The two Iridium launches now mean 56 satellites of the 66-satellite cluster are currently in working orbits. Three more launched scheduled for April, including a Proton, Long March, and Delta launch, will place the remainder in orbit as well as several on-orbit spares. The Iridium system of global wireless phone service is scheduled to become operational this September. Hа сегодня все, пока! =SANA=

Дата: 06 апреля 1998 (1998-04-06) От: Alexander Bondugin Тема: SpaceViews - April 1998 [4/17] Привет всем! Вот, свалилось из Internet... Europe Drops Moon Mission Plans The European Space Agency has dropped plans to send a pair of unmanned spacecraft to explore the Moon early next decade, just a few weeks after publicly announcing the proposal. At a meeting of ESA member nations March 26, the Euromoon 2000 program was dropped. ESA director-general Antonio Rodota said the "financial risks inherent in the mission" were too great for the member nations to shoulder, according to UPI. The Euromoon 2000 mission would have featured a small orbiter, LunarSat, launched in the year 2000 as a secondary payload on an Ariane 5 booster. The spacecraft would have mapped the area where, the following year, the Euromoon Lander would have set down. ESA planned to target the lander for the south polar regions of the Moon, where deposits of ice crystals are believed to exist in permanently-shadowed patches of regolith. The project had been under study for 10 months when ESA announced its existence on March 6, one day after Lunar Prospector scientists reported evidence of water ice in the regolith. ESA had what it termed an "innovative and ambitious implementation plan" which required partnerships with industry and sponsorships to raise some of the funds for the mission. ESA planned to contribute 50 million ECU (US$53 million) of the 200 million ECU (US$212 million) cost of the program. Rodota said the very fast schedule for the mission would require "serious overspending" to keep on track, which would discourage industry investors. General ESA funding problems, which also threaten other science missions like Mars Express, contributed to the decision. No new NASA or ESA missions to the moon are currently funded. Two American companies, LunaCorp and Applied Space Resources, are planning their own missions to the Moon in the next several years using private investments, not government funds. Iridium Makes Pact with Radio Astronomers Motorola and a key radio astronomy center reached an agreement Wednesday, March 18, to allow several hours a day of interference-free observing at the world's largest radio telescope. The agreements means that the Arecibo radio telescope will be free of radio interference from the constellation of 66 Iridium satellites for eight hours a day when Iridium goes online this fall. Under the agreement, satellites will avoid broadcasts when passing over the Arecibo site between 10pm and 6am Eastern time. The agreement also allows for additional protected times for specific scientific opportunities as they arise. Radio astronomers were concerned about the Iridium system's interference at a key radio frequency, 1612 megahertz. Hydroxyl (OH) ions, commonplace in the galaxy, emit at that frequency, and their signals would be drowned out by the more powerful Iridium broadcasts. Hydroxyl ions are produced in red giant stars and are seen in interstellar dust clouds, and serve as a tracer for galaxy evolution. "This agreement is a good compromise in protecting astronomers' ability to observe at this frequency," said Paul Goldsmith, a Cornell University astronomy professor and director of the National Astronomy and Ionosphere Center (NAIC), which operates Arecibo. "Some radio astronomers may have felt that they were entitled to 24 hours a day, but I'm happy that both sides could agree to eight," Goldsmith said. "The agreement should help radio astronomy and communications' use of the spectrum to coexist productively." Arecibo is operated by the NAIC, which receives its funding from the National Science Foundation. The NAIC is headquartered at Cornell University. The Arecibo telescope, 305 meters (1,000 feet) in diameter, was recently upgraded to improve its sensitivity. "We're very pleased that the agreement will help us fully exploit the newly upgraded Arecibo telescope," said Hugh Van Horn, director of astronomy programs at the NSF. While the Iridium agreement will help Arecibo, radio astronomers are concerned in general about the proliferation of communications systems that threaten the ability of Arecibo and other radio observatories to do science. "We must worry about interference with observations at other frequencies and at other radio telescopes as well," said Michael Davis, chair of the National Research Council's Committee on Radio Frequencies. "It's vital to protect access to these very faint whispers of natural radiation that tell us so much about the universe." Asteroid Threat Discussed in Online Chat The dangers of an asteroid or comet impacting the Earth, both in reality and on the big screen, were discussed Thursday evening, March 19, in an online chat that featured scientists and cast members of an upcoming movie. "Killer Asteroids" was the subject of an online chat on Yahoo! sponsored by the National Space Society, Time Magazine, and Paramount Pictures. Featured guests in the chat included astronomer Dr. Pete Worden, former Johnson Space Center director Gerry Griffin, and two key figures from the upcoming movie "Deep Impact", co-producer Richard Zanuck and actor Jon Favreau. The dangers of an asteroid or comet impact, concerns of which were heightened last week by the discovery of an asteroid that will pass within a million kilometers (600,000 mi.), was a key portion of the chat. Worden and Griffin pointed out the dangers of a large asteroid impact. Worden noted that an asteroid 1 kilometer (0.62 mi.) in diameter striking land would create a crater 16-32 km (10-20 mi.) in diameter and kill all life within hundreds of miles of the impact site. A water impact could generate tidal waves that would inundate coastlines thousands of miles away, killing tens or hundreds of millions. Such an impact "would be a global catastrophe, but not a terminal catastrophe," Worden said, who also noted that the odds of dying in an impact are about the same as dying in a plane crash: about 1 in 20,000. The previous week's announcement of the future close pass by asteroid 1997 XF11 has helped promote the upcoming film "Deep Impact," about a large comet on a collision course with the Earth, even if the facts weren't quite clear. "We read all last week how there is in fact a comet headed towards Earth," Zanuck said, apparently confusing the fictional comet from his movie with a real asteroid that will miss the Earth. Zanuck and others said realism was a major emphasis for the movie. "In terms of the realism of the movie, it's as real as one could make it," Griffin, who served as the science advisor for the movie, said. "Because there was so much attention to detail in the astronaut portion, the film was actually quite grueling by acting standards," said Favreau, who plays an astronaut sent on a mission to intercept the comet. Zanuck, who previously co-produced movies like "Jaws" and "The Sting", believed the movie would raise as much "interest and excitement as Jaws did when it was released in 1975." "Deep Impact" is scheduled for release May 8. Hа сегодня все, пока! =SANA=

Russian Comsat Fails A Russian communications satellite launched late last year failed last week, Russian officials reported Monday, March 23. The Kupon satellite, designed to provide communication services for Russian's central bank, lost contact with ground stations last week, apparently when two stabilizers on the spacecraft failed. A spokesman for NPO Lavochkin, the satellite manufacturer, told UPI that the failure of Kupon was completely unexpected. "Our engineers are completely baffled, this is the first failure of this kind in the history of space flights," he said. The satellite, located in geostationary orbit, allowed the Moscow-based Central Bank of Russia to communicate with offices across the sprawling country. Two more Kupon satellites were planned to provide global services. It was launched November 12, 1997, on a Proton rocket from Kazakhstan. The satellite had an insured value of $70 million.

The publisher claims it gave Sagan and his wide Ann Druyan $1.5 million in an advance for a book, the third planned in a four-book deal between Sagan and Random House. The book was due a year ago but never completed; Sagan died of cancer in December 1996. Druyan wasn't available for comment, the Journal reported. Blame It on El Nino: El Nino, the warm-water current that has been blamed for a variety of abnormal weather conditions around the world, is also responsible for something else: slowing down the Earth's rotation, according to scientists at NASA's Goddard Space Flight Center. El Nino has caused the Earth's rotation to slow down such that the day is now 0.6 milliseconds longer than it was before it started. The slow down is caused by the conservation of angular momentum, as the Earth slows down to compensate for a increase in atmospheric speeds caused by El Nino-generated spins. The slowdown is temporary, and the Earth will return to its normal rotation rate after El Nino dissipates. A 1982 El Nino caused a temporary 0.9 millisecond increase in the length of the day. More Kuiper Belt Objects Found: A team of British astronomers have found two new Kuiper Belt objects (KBOs), each no more than 150 km (93 mi.) in diameter and orbiting about 45 astronomical units (6.75 billion km, 4.19 billion mi.) from the Sun. The astronomers, led by Alan Fitzsimmons of Queens's University of Belfast, had expected to find more objects using a more sensitive camera mounted on a 2.5-meter (100-inch) telescope at La Palma, Canary Islands, suggesting that fewer KBOs may exist. Meanwhile, two American scientists have found that KBOs fall into two color classes: a neutral color and an "extraordinarily red" color. The color difference suggests different surface compositions for the two classes of KBOs. Relativistic Frame Dragging: Scientists using two orbiting spacecraft have found evidence that the Earth drags spacetime around itself as it rotates, as predicted by Einstein's theory of general relativity, NASA announced March 27. The American and Italian scientists used data from two laser-ranging to precisely measure their orbits, and found that the plane of the orbits of the spacecraft shifted by about two meters (6.5 feet) per year. This shift is about 10 percent greater than that predicted by theory, but is within their 20-percent margin of error. Gravity Probe B, a future NASA mission scheduled for launch in 2000, should reduce the error in the measurements to within one percent.

Вот, свалилось из Internet... *** Articles *** Operation Mona: America's First Moon Program by Andrew J. LePage Introduction During the opening months of the Space Age, the American space program was in total disarray as a wide range of civilian and military interests vied for control. In the hopes of quickly unifying the military's research projects and securing a major share of the nation's future space program for the Department of Defense (DoD), Secretary of Defense Neil H. McElroy established the Advanced Research Projects Agency (ARPA) on February 7, 1958. ARPA was charged with coordinating all the DoD's advanced research, including their space projects, to help eliminate duplicate efforts. Since the entire space program at this time was connected in some way to the military, by default ARPA would be in charge of the American space program until Congress and the Administration made other arrangements. On March 27, 1958 President Eisenhower approved McElroy's plan for ARPA to undertake its first series of space missions. The most ambitious of these was labeled "Operation Mona" which called for the launching of five probes to the Moon. Three of these would be lofted by the U.S. Air Force (USAF) Ballistic Missile Division while the Army Ballistic Missile Agency (ABMA) would be responsible for the last two. ARPA believed that a successful military lunar mission would not only help the United States leap frog ahead of the Soviet Union in the space race but also add credibility to the military presence in space. It was felt by some that these missions could help prevent any civilian space agency that Congress might create from taking an important share of the space program from the DoD. In addition, the long-distance guidance and tracking experience gained in the project would be useful for future scientific and weapons programs. USAF Moon Probe The USAF would have the first shot at the Moon with the more ambitious of the two sets of ARPA probes. For these missions the USAF planned to use their new Thor-Able rocket as the basis of a launch vehicle. The two-stage Thor-Able 0 had been cobbled together from existing rocket components to perform reentry tests of the Atlas ICBM warhead design. USAF planners felt the Thor-Able 0 could be modified with relative ease into the three-stage Thor-Able I Space Carrier for their lunar mission. The first stage of this rocket was the Thor intermediate-range ballistic missile (IRBM) with a range of 2,600 kilometers (1,600 miles). The Thor, built by the Douglas Aircraft Company (which became McDonnell-Douglas and much later merged with Boeing) for the USAF, was about 18.6 meters (61 feet) long and 2.4 meters (8 feet) in diameter at the base. The Thor DM1812-6 variant used for the Thor-Able I incorporated a Rocketdyne MB-3 powerplant burning kerosene and liquid oxygen (LOX) to produce 668 kilonewtons (150,000 pounds) of thrust. In the Thor-Able configuration, Thor's nuclear warhead was replaced with an adapter upon which the upper stages were mounted. These stages were modified versions of the ones originally developed for the Navy's Vanguard program. The second stage was modified by STL (Space Technology Laboratory - a division of TRW) for Douglas Aircraft for the Thor-Able program. In the Able configuration, the second stage retained its original 0.85 meter (2.8 foot) diameter but it was shortened to 5.8 meters (19 feet) to optimize its size for the Thor-Able mission. The second stage's original Aerojet General AJ10-37 liquid propellant rocket engine was replaced with the substantially improved AJ10-41 engine for the Thor-Able I. The third stage was the fiberglass-cased X-248 Altair solid motor built by Allegheny Ballistic Laboratory. This innovative lightweight motor had been developed by the Navy as a backup for the more conventional motor developed by the Grand Central Rocket Company for Vanguard. The X-248 was later incorporated into several other rocket designs including a high performance version of the Vanguard. All together, the Thor-Able I was 27 meters (88 feet) tall from its base to the top of its hemispherical "mushroom cap" payload fairing. Since the Able stages were essentially the same as those used by Vanguard, they unfortunately shared many of its problems. By the end of the summer of 1958, malfunctions in the second stage of the Vanguard were responsible for four of Vanguard's five failures. During this period the upper stages of the Vanguard operated correctly only once to place Vanguard 1 into Earth orbit on March 17, 1958 (see "Vanguard 1: The Little Satellite That Could" in the March 1998 issue of SpaceViews). The Thor-Able 0 reentry tests were the only additional successes for this upper-stage design during this time. The first Thor-Able 0 was launched on April 23, 1958 but blew up 146 seconds into the flight because of a turbopump failure in the Thor No. 116 first stage. While the payloads were not recovered, the Thor-Able 0 itself operated successfully on the flights launched on July 9 and 23 of 1958. Theoretically, the Thor-Able I could place 160 kilograms (350 pounds) of payload into a 480-kilometer (300-mile) high orbit or 39 kilograms (85 pounds) into a direct ascent escape trajectory. Only months after the launch of the first Earth satellites, the USAF planned to send its three Moon probes into lunar orbit. Under contract by the USAF, STL built three 38-kilogram (84-pound) spin-stabilized probes each carrying 18 kilograms (39 pounds) of scientific instruments. The orbiter consisted of a wide cylindrical belt joining two flattened fiberglass cones. At the end of the bottom cone was a ring of eight vernier solid rockets which could be fired to correct the probe's trajectory. At the other end of the probe was a single Thiokol Falcon solid rocket motor that would be fired 65 hours after launch by to slow the probe into lunar orbit. Removable black and white stripes applied to the probe's exterior before launch were used for passive thermal control. The probe's wide belt carried the control systems, batteries, radio, and scientific instruments to measure magnetic fields, radiation, and micrometeorites. The USAF probe also carried a simple camera in the hopes of obtaining the first close-up images of the Moon. This camera weighed only 400 grams (14 ounces) and consisted of a small parabolic mirror that focused infrared radiation received from the Moon onto a special cell. One line of the image would be obtained for each revolution of the spinning probe. The scene could then be slowly built up one line at a time as the probe moved in relation to the Moon. On the remote chance that the probe should accidentally impact the Moon, the spacecraft was decontaminated to minimize the chances that organisms from Earth would corrupt any future biological investigations on the Moon. The original plan called for all three USAF probes to be launched during the summer of 1958. Hа сегодня все, пока! =SANA=

The ABMA Moon Probe After the USAF launched their three probes, the ABMA was authorized to proceed with theirs. The ABMA Moon project had its origins in an early-1956 proposal with the Jet Propulsion Laboratory (JPL) to use a modified ABMA-developed Jupiter IRBM to launch two deep space probes during the IGY. With ARPA's approval, Wernher von Braun and his team set out to build the launch vehicle that they needed for the mission: The Juno 2. This new launch vehicle consisted of a modified Jupiter IRBM topped with an improved version of the JPL solid rocket cluster used on the Juno 1 launch vehicle (see "Project Orbiter: Prelude to America's First Satellite" in the January 1998 issue of SpaceViews). As the first stage of the Juno 2, the kerosene and LOX tanks of the Jupiter retained their original 2.67 meter (8.75 foot) diameter but were lengthened by a total of 0.92 meters (3.0 feet) making the rocket 16.84 meters (55.24 feet) long. This prolonged the burn time of the 668 kilonewton (150,000 pounds) thrust Rocketdyne S3D engine by 20 seconds to a total of 182 seconds. Mounted on top of the first stage under an aerodynamic shroud was the instrument compartment and a JPL-developed, three-stage solid rocket cluster similar to that used by the ABMA Jupiter C and Juno 1 rockets. Modifications of this cluster from these earlier versions included filling the third and fourth stages with a higher performance propellant and changing the original stainless steel casing of the fourth stage to a lighter weight titanium casing. The upper stage cluster of the Juno 2, when used with the Jupiter C and Juno 1 launch vehicle, was quite reliable if somewhat inaccurate due to the inconsistent performance of early solid rocket motors. The three Jupiter C flights were largely successful and two of the three Juno 1 failures were due to an upper stage malfunction. It operated successfully three times, orbiting Explorers 1, 3, and 4 (see "Explorer: America's First Satellite" in the February 1998 issue of SpaceViews). Theoretically, the Juno 2 could place 43 kilograms (95 pounds) of payload in a 480-kilometer (300-mile) high Earth orbit or up to 7 kilograms (15 pounds) of useful payload on a direct ascent escape trajectory. On May 2, 1958 ABMA contracted the builder of the first Explorer satellites, JPL, to build a pair of tiny probes that the Juno 2 could launch towards the Moon. Weighing just 5.9 kilograms (13 pounds) each, the probes were essentially a 23-centimeter (9-inch) wide cone with a 8-centimeter (3-inch) spike antenna on the top. They were 51 centimeters (20 inches) long and constructed of gold-washed fiberglass. The exterior was gold plated and striped with paint for passive thermal control. The electrically conductive gold plating on the cone also served as an unsymmetrical dipole antenna element in conjunction with the spike antenna. At the squat cylindrical base of the probe was a despin mechanism consisting of two 1.5-meter (60-inch) long weighted wires. As the wires unwound, the payload's spin rate would decrease from 415 to 11 revolutions per minute. Located inside the probe was a 500-gram (1.1-pound) transmitter with an effective power of 180 milliwatts. The power supply for the transmitter and instruments consisted of a set of eighteen mercury cells. Originally these JPL-built Moon probes were to carry a tiny photographic package capable of obtaining a single photograph of the Moon's far side during a close flyby. A photoelectric triggering device would trip the camera's shutter when the Moon was in the detector's field of view and closer than 32,000 kilometers (20,000 miles). But with the discovery of the Van Allen radiation belts by the first Explorer satellites, the ABMA Moon probes' primary instrument was changed to a pair of Geiger-Mueller tubes to obtain data on the radiation environment between the Earth and Moon. The original photoelectric triggering device was retained as an engineering test for future systems. With the new instrument, the mission of this probe was also changed. Instead of a close flyby, the probe was now destined to impact the surface of the Moon 33 hours and 45 minutes after launch. Given the inherent inaccuracy of direct ascent trajectories, the relatively crude nature of the Juno 2 solid rockets and guidance system, as well as the lack of any course correction capability, the ABMA Moon probe would be lucky to make it anywhere near the Moon never mind hit it. Nonetheless, at this early stage of space exploration a lunar flyby was just as valuable scientifically as a direct hit. Since the ABMA had to wait until after the USAF probe launches, September of 1958 was set as the tentative launch date for their first Moon shot. With luck the ARPA-sponsored Moon probes, in addition to providing valuable IGY data, would get America ahead of the Soviet Union in the Space Race.

In the Eye of March Storm by Jeff Foust It can be hard to believe that a handful of private citizens can make a significant difference in space policy. Positions seem to be too entrenched, special interests appear to be to powerful, and elected officials seem to be too apathetic towards space for any group of citizens to make a difference. Yet, over the last few years, the weeklong "March Storm" lobbying effort, organized by ProSpace, has proven surprisingly effective in shaping national space policy through the support of specific programs and legislation. What started with 9 people meeting with 52 Congressional offices in 1995 had grown to over 50 people meeting with 220 offices just two years later. Those efforts helped successfully support everything from Air Force reusable launch vehicle funding to X-33 and the Commercial Space Act. How can a few dozen space activists meeting with Congressional staffers have that much power? I took part in March Storm this year to see how effective such an effort can be. After walking the halls of Congress for just a couple days, I'm glad I did. Training The 1998 version of March Storm actually started on February 28, with an optional two-hour briefing session on a Saturday evening, going over some basic details about how Congress works. The week really got started early (8:30am) on the following Sunday morning, when all of us -- about 50 -- participating in the event gathered in a meeting room at the Quality Inn Iwo Jima Hotel in Arlington, Virginia. It was there that we would go over the presentation we would give to Congressional staffers, and practice that presentation under a number of circumstances. To get started, though, we went through a little ice-breaking exercise. We mingled around the room, and on command, stopped, paired up with someone, and briefly explained why you spent your own time and money coming to Washington for March Storm. The idea was to help articulate your vision, a key towards a successful meeting with a staffer. The exercise turned out to be quite fun: you got the opportunity to better explain why you were doing this, and to exchange ideas with other people to help augment and revise your vision. After this, the meeting got down to the nuts and bolts of the presentations we would be giving in the coming week. We went over "A Citizen's Space Agenda", a ProSpace briefing packet that would be the basis for our presentations and would also be given to the staffers we met. The emphasis of the packet was to gain support for three projects and pieces of legislation that would provide near-, mid-, and long-term support for opening the space frontier. The first, immediate objective was to seek support for the Commercial Space Act. The Act, H.R.1702, passed the House last November and was at the time about to be considered by a Senate committee. (A week after March Storm the Senate Commerce committee approved the Act, passing it on to the full Senate for its consideration.) In addition, we also sought support for the Civilian Space Authorization Act, another piece of legislation that had passed the House and was being debated in the Senate (it, too, was approved by the committee the following week). Both bills included provisions that would support commercial space. The second objective was to seek support for new launch vehicle technology development. This funding would focus on leading-edge technologies companies were not willing to invest in yet, but could in the future if they were proven to work. NASA's Future-X program is designed to do exactly that: test specific new technologies that promise to reduce launch costs. A major goal of March Storm was to get additional funding, $100 million for fiscal year 1999, for Future-X, as well as $50 million in 1999 for the Air Force's Military Space Plane, which could have similar benefits. The third objective, long-term in scope, was a re-examination of solar power satellites (SPS). A "Fresh Look" study released last October showed that SPS could be a feasible source of power, provided that cheap access to space -- the focus of the first two objectives -- became a reality. While functioning SPS systems are at least a decade down the road, studies are needed now to further refine the concept and see what was truly feasible. The goal of March Storm was to raise this funding from the $5 million planned in 1999 to $25 million. Once we had gone over the briefing material, we practiced giving presentations to staffers. While we had a folder stuffed with briefing packets and supporting material to give to each staffer, we had to be able to communicate more effectively than by leaving through a packet of handouts. We weren't there to walk a staffer through a handout page by page; we were there to communicate our vision of an open space frontier, and to press upon them the importance of the legislation and programs we wanted their Congressmen to support. The practice took us through a series of scenarios, from an indifferent staffer to one openly hostile to space. We learned the things to do, and not to do, to effectively communicate with them. By the end of the day we at least had some idea of what the presentations were going to be like. Despite the preparation, though, I still felt at least a little nervous about the presentations that would begin tomorrow. Sunday's practice had been with fellow space activists. Tomorrow would be the real thing, trying to convince Congressional staffers of the merits of our ideas. Before we adjourned for the night we split up into teams and got our list of appointments for Monday. Briefings were done in teams of 2 to 4 people. Teams help provide support during your presentation: if you didn't know the answer to a staffer's question, then someone else on the team could step in. At least one member of a team would be a veteran of past March Storms and thus provided guidance for the first-timers. Teams also allowed one person to concentrate on taking detailed notes of the meeting, which would be used for followup action and as a reference for future March Storms. Hа сегодня все, пока! =SANA=

Walking the Halls of Power On Monday morning we headed over as a group to the Rayburn House Office Building, whose large basement cafeteria would be our meeting place during the week. I got together with the others on my team: Frank Johnson, a March Storm veteran who is a graduate student at MIT; and David Richey, a fellow first-timer who drove up with several other students from Embry-Riddle Aeronautical University in Florida. We had six appointments Monday, all with staffers for members of the House of Representatives. Our first meeting Monday morning was with a staffer for a Republican congressman from upstate New York. I felt a little nervous going into the meeting, which we held with the staffer in the Congressman's office (he was out of town). Then we just started to talk. We talked about our vision of an open space frontier, and why it was important, and what the staffer's boss could do to support that through legislation and research programs. All the nervousness went away. We were really just communicating our vision to yet another person. This was going to be fun. We soon fell into a rhythm. Before the meeting our team would have a "pre-briefing" where we went over the background information ProSpace provided on the member and staffers, and discussed what issues to emphasize. Not all issues would get the same weight with all staffers: a meeting with one whose boss is on a defense-related committee might hear more about the military spaceplane, while a staffer for another Congressman who's interested in the environment might hear more about the benefits of solar power satellites. We also planned who would take the lead in giving the briefing and who would play a supporting role or take notes. After each briefing we would immediately meet (after walking a safe distance from the Congressman's office!) for a debriefing to discuss the results and our impressions. We made note of any specific issues the staffer raised, their reaction to our request for support for the legislation and programs, and any interest in follow-up on specific issues. We'd then move on to the next appointment and repeat the process. Not all meetings were the same. Some staffers seemed disinterested; our meetings with them were fairly short. Others, though, took a great interest in what we were doing, and we had much longer meetings with them to go into our issues into greater detail. Some meetings were pleasant surprises. We met with a staffer with the office of Rep. Joseph Kennedy (Frank's congressman) on Monday. Frank had gone there last year and found the staffer disinterested. This year, though, were was a new staffer who took a keen interest in the issues, particularly solar power satellites. What we had anticipated to be a perfunctory 10-minute meeting turned into a discussion lasting over a half-hour. At the end of the day all of us March Stormers would gather together for dinner to discuss the day's events: the highs, the lows, and the just plain unusual. We exchanged notes and planned for the next day's meetings. It was a chance to relax after a long day of meetings (each team generally had 6-7 meetings a day) and, for those who were staying, get ready for the next day's set of meetings. This would continue throughout the week. By the end of the week 48 people has met with 246 Congressional offices. Judging March Storm's Effectiveness There was clearly no lack of effort put into March Storm by the people who participated or the ProSpace volunteers who helped put it together. But how has that effort translated into results? Charles Miller, head of ProSpace, sees the biggest progress being made in the Senate. "Two years ago, before the 1996 March Storm, the U.S. Senate was considered the 'black hole of space,'" he said. "Almost nobody knew anything about it there, and there was absolutely zero Senators who were leaders on the issue." Former Senate staffer Tim Kyger agrees. With 435 members in the House, he noted, a statistical distribution means that you'll have at least a couple of strongly pro-space members. With only 100 Senators, though, only "every once in a while" will you get a strong pro-space Senator. That, combined with NASA's low position in a Senate committee more concerned with communications, aviation, and transportation, meant that space issues got little attention in the past in the Senate. "Today, a number of Senators have stepped forward to take an active leadership role on space, and most Senate offices know something about the issue," Miller said. "The Senate Commerce Committee staffers responsible for the Commercial Space Act told me they are receiving calls from staffers all over the Senate about the bill." Why the change? Kyger believes that Senate support for the Commercial Space Act and a NASA authorization bill stems from a number of reasons, and does not necessarily reflect increased internal interest in space issues so much as more external support for the legislation, including backing from NASA and the space industry. However, March Storm has played a key role in increasing Congressional awareness about space issues, because the private space activists, taking their own time and spending their own money to participate, lack the vested interests commercial lobbyists and government officials have. Staffers meet with March Stormers and "it blows them away" that citizens care enough about the issues to go to great lengths to communicate them, Kyger noted. Both new and veteran March Stormers saw interest in March Storm issues from Congressional staffers. "The staffers still react the same way that they always did, which is with polite interest," Frank Johnson, participating in his third March Storm, said. "However, I did notice that the staffers were somewhat more receptive to the possibility of private space development. It was easier to get them out of the 'space = NASA' mindset." "I got an overwhelming sense of support for space-related issues," said Dale Gray, who traveled from Boise, Idaho to participate in his first March Storm. One exception to that support, he noted, was the International Space Station, whose cost overruns have some under some criticism. Both Gray and Johnson are looking forward to participating next year, schedules and finances permitting. "To me it is important to deliver the overall vision of private space development by individuals," Johnson said. "If people can't see their personal future in space then we'll never get off the ground." Hа сегодня все, пока! =SANA=

DiGregorio [Editor's Note: In the December 1997 issue of SpaceViews, we published a review of the book "Mars: The Living Planet" by Barry DiGregorio. Mr. DiGregorio has requested, and we have granted him, an opportunity to rebut the review. Please note that this rebuttal and the original review do not necessarily reflect the opinions of this publication, the National Space Society or its Boston chapter.] When I read the unfavorable SpaceViews review of my book "Mars: The Living Planet" I became concerned because the issue of whether or not life on Mars exists or existed is perhaps one of the most significant questions in the history of science. I became interested in writing this book because after numerous conversations with Dr. Gilbert V. Levin and about thirty other scientists (acknowledged in my book), I thought there was good evidence that the Viking mission to Mars may have in fact, discovered living microbes. The review says "Mars The Living Planet makes the bold, but poorly-supported claim: that life has been discovered on Mars..." It is this single point in the review that disturbed me the most. Why? Because there is substantial evidence to support the notion the microbes were detected on Mars in 1976. I feel the four years of research I have put into this book shows without question that strong evidence for life on Mars exists. The three Viking biology experiments all returned evidence that could be interpreted biologically, but when another instrument (the GCMS), designed to look for the dead remains (organic matter) of life, detected nothing, was it claimed by some scientists that no evidence for life on Mars existed. Yet this instrument had many problems. En route to Mars, the Viking spacecraft had the unique ability to perform tests of the various components inside the lander. When tests where conducted inside the GCMS, several leaks were discovered, and one of three ovens designed to heat Martian soil samples was shown to be inoperative. On the surface of Mars, the GCMS science team could not even get a reading to whether they had a soil sample in their test chamber. Was it empty? All the GCMS ever reported from its soil analysis was that there appeared to be carbon dioxide and water vapor in it, two components of the Martian atmosphere. Since the scientists that now upheld the view that the GCMS was correct about organic material on Mars, they had to construct a theory for why it did not exist. They proposed that hydrogen peroxide was being formed in the atmosphere of Mars through a process of water molecules being split up by ultraviolet rays from the sun. The hydrogen peroxide would bleach any organic material out of the soil. The problem is that hydrogen peroxide is destroyed immediately by ultraviolet light, and since Mars has no ozone layer to speak of, there would not be any protection to prevent these molecules from destruction. The SpaceViews review then comments about Levin's work on the color of the Martian rocks. Levin did observe spots on the rocks that change with time and seasons, yet he is criticized by the reviewer "to everyone else the rocks appeared gray". Well, you better study your Viking and Mars Pathfinder images better than this -- the rocks and soils of Mars are indeed multi-colored. Some of the rocks are blue, and even white. These studies confirm Levin's theory of green-colored patches on the rocks and in the soil. The reviewer says my book is a disappointing study of life on Mars. I feel it is the most comprehensive study ever written. Clearly the issue of life on Mars is a volatile one, due to personal agenda's, politics, and religious beliefs, all subjects touched on in my book and usually avoided by others. Is not the goal of science to answer questions? One of the greatest questions in the history of science was posed by the Viking results: is there life on Mars, is there life in the universe, and then to have it simply dismissed without appropriate investigation based on the GCMS results alone, is in my opinion ludicrous. That is the point of my book. For all those that would like a review of the scientific evidence, I suggest you read Dr. Gilbert V. Levin's invited scientific paper presented to last summers annual SPIE meeting in San Diego, CA where he concludes "the Viking LR experiment detected living microorganisms in the soil of Mars". All the current arguments are discussed in it. Levin's scientific paper can be accessed online by going to: http://www.biospherics.com/mars/spie/spiehtml.htm Hа сегодня все, пока! =SANA=

Вот, свалилось из Internet... *** Book Reviews *** by Jeff Foust Sharing the Universe Sharing the Universe: Perspectives on Extraterrestrial Life by Seth Shostak Berkeley Hills Books, 1998 softcover, 206pp., illus. ISBN 0-9653774-3-1 US$14.95 The question of the existence of intelligent life in the universe has generated some diverse viewpoints. Some believe the circumstances by which intelligent life arose on Earth are so unique as to make it very unlikely life could exist elsewhere. Others believe the universe is filled with intelligent life, and that these aliens have made numerous visits to Earth, carved faces into Martian mountains, etc. In between are those who believe it's quite possible that intelligent life exists in the cosmos but hasn't visited us; this is the rationale of Search for Extraterrestrial Intelligence (SETI) projects around the world. Top SETI scientist Seth Shostak makes a strong case for this middle view in his book "Sharing the Universe". Much of Shostak's book is an effort to destroy the myths and other commonly-held, but incorrect, beliefs about the possibilities of extraterrestrial intelligence. He is a strong believer in what he terms the "Principle of Mediocrity": that is, there is nothing terribly special about our planet and the solar system. This principle supports his argument in two ways. Because the Earth is not terribly special, it's reasonable to believe that other worlds exist in our galaxy that are capable of supporting life and allowing the development of intelligent life. On the other hand, because there's nothing special about the Earth, there's little reason why it should be the galactic destination du jour for a whole host of alien races, as many believe. Because extraterrestrial life of some kind is probably out there, but is unlikely to bother finding us, we have to search for other evidence of its existence. Searching for radio signals from alien intelligences quickly becomes the preferred method for searching, since its far quicker and less expensive than any kind of direct exploration by interstellar spacecraft. Shostak provides a good summary of SETI work to date, from Project Ozma nearly 40 years ago to the privately-funded Project Phoenix and BETA today. Shostak provides a compelling argument that extraterrestrial intelligence does exist, but in a manner nothing like that depicted by most Hollywood movies or on the front pages of tabloids. He presents his arguments in a writing style that is easy for a layman to understand, and fun to read, too. Even if you're not a supporter of SETI, after reading "Sharing the Universe" you'll be hard pressed not to agree with Shostak's arguments about intelligent life in the universe. Two Books on Exotic Astrophysics Cosmic Bullets: High Energy Particles in Astrophysics by Roger Clay and Bruce Dawson Helix Books (Addison-Wesley), 1998 hardcover, 208pp, illus. ISBN 0-201-36083-7 US$22.00 Ripples on a Cosmic Sea: The Search for Gravitational Waves by David Blair and Geoff McNamara Helix Books (Addison-Wesley), 1998 hardcover, 208pp., illus. ISBN 0-201-36082-9 US$22.00 There's always been a fascination with some of the exotic particles and waves in the universe. These exotic forms of matter and energy are diagnostic tools for understanding the nature and origin of the universe. Scientists are moving to higher energy particles and more exotic forms of energy in their quest to understand the universe. Two books in a new series of books by publisher Addison-Wesley, "Cosmic Bullets" and "Ripples in a Cosmic Sea" explore these exotic phenomena. "Cosmic Bullets" explores our understanding of cosmic rays, subatomic particles that can travel through space at speeds within a tiny fraction of the speed of light. Authors Roger Clay and Bruce Dawson discuss the history of cosmic ray research, with a emphasis later in the book on one particular cosmic ray observatory, Fly's Eye, located in the Utah desert. The roles of cosmic rays in our understanding of phenomena such as neutron stars and black holes are explained in a language aimed at the layman. "Ripples on a Cosmic Sea" explores a phenomenon still limited to theory: gravitational waves. These waves of gravitational energy, as opposed to the electromagnetic waves that make up light, have been predicted by relativity theory but have yet to be observed. In a language aimed at newcomers to the subject, they explore the theory of gravitational waves and efforts to detect them, as well as plans for the future (although here more attention could have been given to the current status of such efforts as LIGO, an American gravitational wave observatory under development.) Both books attempt to introduce fairly exotic areas of astrophysical research to the general reader. In that respect, both succeed quite well. If you have an interest in these areas of research, and trying to gain a better understanding of the universe, you'll be well served by either book. Heavenly Knowledge Heavenly Knowledge: An Astrophysicist Seeks Wisdom in the Stars by Dr. Fiorella Terenzi Avon Books, 1998 hardcover, 224pp., illus. ISBN 0-380-97412-6 US$22.00/C$29.00 Dr. Fiorella Terenzi has been described as "a cross between Madonna and Carl Sagan," according to Time magazine. Let us be clear here that Terenzi does not combine the scientific intelligence of Madonna and the musical skills of Sagan. Terenzi has made a name for herself in both the astronomical and musical communities with what she calls "acoustical astronomy", converting the radio signals from astronomical sources into sound. She describes her unique insights on the universe in "Heavenly Knowledge". Terenzi writes that she wants to bring the wonder back to astronomy by treating astronomy less abstractly and mathematically, and using the universe to gain "poetic truths" about our lives. She keeps up this theme throughout the book, virtually personifying phenomena from supernovae to binary stars, comparing them to events in our own lives. She aims for a "dynamic relationship" with the universe, a "dance between the knower and known." It is difficult to classify this book. Although astronomy is discussed extensively in the book, in a number of sidebars, it is not strictly an astronomy book. Although Terenzi discusses many aspects of her life, it is not really a biography. It is closer to a philosophical book, trying to tie together the nature of the universe with the nature of humankind. If you're looking for a book to explain the universe, you'll be disappointed by the book. If you're looking for a different. novel comparison between the cosmos and humanity, though, you will at least find this book interesting. Hа сегодня все, пока! =SANA=

Boston NSS March Lecture Summary by Jeff Foust Using nothing more than the supersonic flow of air over a special projectile may be the key to reducing launch costs in the future, according to research by one local company that was presented at the March 5 meeting of the Boston National Space Society. Robert Hohlfeld, a professor at Boston University and vice president for research and development at HyperKinetics, Inc., an Arlington, Massachusetts, firm, discussed "Supersonic Projectiles Producing Thrust by External Combustion" based on research conducted by his company. Hohlfeld said he and his company were interested in ways to reduce the cost of space access. However, HyperKinetics -- "three guys in the basements" according to Hohlfeld -- couldn't compete in standard technologies. Instead, they looked at new technologies that would be simple to build and could reduce launch costs. Hohlfeld and his colleagues turned to methods where the air flow around a vehicle itself could be used as part of a propulsion system. If the air flow was moving supersonically around the projectile (as a result of firing the projectile at high speed), and the projectile shaped in the right way, the frictional heating caused by the airflow could trigger the combustion of fuel on the surface of the projectile, which would create a thrust directed away from the projectile in the opposite direction of motion, further propelling the vehicle. Hohlfeld emphasized the basic nature of the concept. The theory was based on classical methods in supersonic flow ("something a grad student in aeronautics would be comfortable with", he quipped). The projectile would use a double-wedge shape, another basic shape from aeronautics, to shape the air flow around the projectile. HyperKinetics considered testing the concept in wind tunnels, but with Mach 3 wind tunnel time costing about $3,000 a day, they sought a simpler test procedure: a .30-caliber rifle. Hohlfeld and his colleagues shaped their initial projectiles like 30-06 bullets so they could be fired from a gun. The projectiles were made with magnesium, roughened on the tail wedge to promote combustion, with a copper sheath in the middle portion of the projectile. The rifle would fire the projectiles at about Mach 2.7. Hohlfeld said this was enough to start combustion on the tail section of the projectiles: the speed needed to be at least Mach 1.5, and preferable Mach 3 or higher. Once you got the speed to Mach 4, he said, "things really begin to take off." The HyperKinetics team built dozens of projectiles, testing different shapes and different techniques to roughen the tail section to improve combustion. They started test firing in June of 1994, using a farm field in Holland, Massachusetts. They set up a 100-yard test range, with the rifle at one end. Two pairs of microphones, one pair spaced a yard apart one end of the range and the other pair at the far end of the range, were used with microsecond-accurate timers to determine the speed of the projectiles. The tests, completed in November 1995, were encouraging. Various forms of their projectiles were travelling 5-10% faster at the far end of the track than when they were initially shot out of the rifle, evidence that combustion was taking place and thrust was accelerating the projectile. In comparison, test projectiles of similar shapes but not able to combust ended up 5-10% slower at the far end. The increase in speed for the projectiles translated into an acceleration of 45 g's! While their tests were a success, HyperKinetics has reached the limits of their test equipment. Each test firing was overpressuring their gun, threatening to blow out the breech, so they had to stop testing and seek more advanced equipment. They applied for and received a Phase 1 SBIR from the Air Force to continue their research, gaining access to specialized equipment at Eglin Air Force Base. At Eglin, they had access to Doppler radar to better track the projectiles, as well as an indoor ballistics range where they could get shadowgraphs -- very high speed photographs -- of the vehicle in flight. However, for safety reasons, they had to fire their projectiles at lower velocities, which made the system seem less effective. Their Air Force data, though, did help show that the projectile was generating thrust by combustion of magnesium in the airflow. The radar profile of the projectiles and shadowgraph images of the projectile and airflow show evidence that thrust is taking place. They plan to investigate this further in the next few months when they gain access to special barrels in which they can fire the projectiles at higher speeds. Still, Hohlfeld admits it's a long way from firing 30-06 projectiles from a gun to developing a new low-cost launch system. Since the current projectiles are spinning at 300,000 rpm when shot out of the gun, they would need to find a way to despin them if used as a launch system. A gun launch system wouldn't have to be used, either, he said: any way you could get the system to Mach 3, such as using a conventional booster, would be enough to start combustion. A different fuel than magnesium would also be desirable, he said, but that requires meter-sized projectiles, at the very least. Hа сегодня все, пока! =SANA=

Europa Ocean Explorer Project by Larry Klaes Recently, NASA decided to fund the Europa Orbiter mission, which would leave Earth in 2003 and arrive at this fascinating Galilean moon three years later. Becoming the first spacecraft to orbit Europa, the probe would photograph and radar-map in great detail the Jovian satellite's surface to see just how thick its ice crust is and if there are any openings in it to the proposed ocean of liquid water beneath. If the Europa Orbiter does indeed find such an ocean and ways to reach it through the ice, then a follow-on mission to explore those alien seas with a series of hydrobots would be the logical next step in planetary exploration. Boston NSS Vice President Larry Klaes is proposing a project to design such a mission to Europa, which may be one of the best candidate worlds for harboring life in our solar system. Called the Europa Ocean Explorer Mission, Larry envisions a main bus spacecraft, or "mothership", which would either flyby or orbit the moon and drop a number of small probes onto this world. Some of these landers would explore the surface, while others would find their way beneath the ice into the Europan waters and reveal their long-held mysteries. Larry is inviting interested individuals from diverse backgrounds to form a committee to flesh out this proposed space mission. You do not have to be a member of the NSS, just enthusiastic and willing to share your ideas. The goal as it presently stands is to eventually produce a detailed mission layout, working models of the spacecraft, and a presentation to NASA. You may contact Larry for further details at: lklaes@learningco.com The Europa Orbiter Mission Web site URL is: http://www.jpl.nasa.gov/pluto/europao.htm. Come and explore a new world!

Note: Go to http://hea-www.harvard.edu/QEDT/jcm/space/jsr/jsr.html for back issues and other information about Jonathan's Space Report.] Shuttle and Mir RKK Energiya's automated cargo vehicle Progress 7K-TGM No. 240 was launched on Mar 14 and named Progress M-38. Vehicle 240 is specially modified to carry the second VDU (Vynosnaya Dvigatel'naya Ustanovka, External Engine Unit) propulsion unit. If vehicle 240 is similar to the vehicle 209 (Progress M-14) which carried the first VDU in 1992, the unit is mounted externally on a special structure between the cargo module and the service module, replacing the OKD fuel section present on normal Progress vehicles. The crew will spacewalk to extract the VDU from Progress and place it on the end of a Sofora boom extending from the Kvant module. The VDU is used to provide attitude control capability for the station. Launch mass of Progress M-38 was 7007 kg. By 0320 UTC on Mar 15 it had successfully completed its first two orbital maneuvers. It replaced Progress M-37 at the docking port on the Kvant module, with a successful docking on Mar 16. Progress M-37 undocked on Mar 15 at 1916 UTC and was deorbited at 2303 UTC over the Pacific. Columbia was moved to the VAB on March 16 in preparation for STS-90. On Mar 24 it was rolled out to pad 39B. Recent Launches NASA has begun drop testing of an X-38 test vehicle. The X-38 is a project to develop a lifeboat (crew return vehicle) for the Space Station. X-38 V-131 was dropped from a B-52 on Mar 12, flying 7 km over Edwards AFB, and parachuted to the desert. Vehicle 131 is a subscale test prototype, not a spaceworthy craft. Two other 130-series X-38's will be drop tests prior to the space flight of the full-scale V-201 in the year 2000. Lockheed Martin Astronautics launched the last Atlas II, AC-132, from Cape Canaveral on Mar 16. It placed a Hughes HS-601 satellite in orbit for the US Navy. UHF Follow-On F8 is the first Block III UHF Follow-On satellite, replacing the old FLTSATCOM satellites. It carries UHF, EHF and Ka-band transponders, including a video broadcast payload. Future Atlas launches will use the IIA and IIAS models, as well as the forthcoming IIAR variant. The French SPOT 4 remote sensing satellite was launched on Mar 24. Developed by Matra Marconi Space/Toulouse for CNES, the 2755 kg satellite provides 10-m resolution images with a wide field of view. SPOT 4 also carries a wide field 'vegetation' imager and a laser communications experiment. Launch was by an Arianespace Ariane 40 rocket, the base Ariane 4 model with no strap-on boosters. The liquid hydrogen fuelled third stage of the Ariane 40 entered an 800 km sun-synchronous orbit together with SPOT 4. The Kakehashi satellite has begun orbit raising maneuvers.
