    Дата: 27 января 1998 (1998-01-27) От: Alexander Bondugin Тема: This Week On Galileo - January 26 - February 1, 1998 Привет всем! Вот, свалилось из Internet... THIS WEEK ON GALILEO January 26 - February 1, 1998 This week Galileo continues to transmit to Earth pictures and science data acquired and stored on the onboard tape recorder during the spacecraft's close flyby of Jupiter's moon Europa in December 1997. Meanwhile, here on Earth, flight team members continue to examine engineering data gathered during a test of the spacecraft's attitude control system that was performed about a week and a half ago. The attitude control system has behaved anomalously on two occasions since December 1997. Preliminary findings seem to confirm initial theories that the anomalous behavior was caused by a hardware error in one of the spacecraft's two gyroscopes. Work on confirming these findings will continue throughout the week. Scheduled for transmission to Earth this week are the final portions of the fields and particles' observation of the interaction between Europa and Jupiter's magnetic and electric field environment. There are also observations by Galileo's camera of the wedged regions of Europa and science information from the Near Infrared Mapping Spectrometer (NIMS) of the same wedged region of Europa. The NIMS data will help scientists learn about the types of materials found in this wedged region. Other NIMS observations to be returned this week monitor changes in Io's surface activity. This monitoring will aid observation planners later in the Galileo Europa Mission, when the spacecraft approaches its close flyby of Io in late 1999. Finally, the Photopolarimeter Radiometer team returns data from an observation designed to look for hot regions on Europa. Once processing and transmission of these observations are completed, the spacecraft starts with re-processing and re-transmission of observations that may have previously been processed and transmitted to Earth. This second "pass" through the recorded data provides the science teams with the opportunity to fill up gaps in information caused by transmission problems the first time around. The second pass also provides the opportunity to re-play portions of observations that have been identified as particularly interesting or to simply add additional data from a particular observation. First on the re-transmission schedule we find an observation of Ganymede's Gilgamesh region. This observation is expected to help determine the age of Europa's surface by allowing scientists to compare the number and types of craters in this region of Ganymede's surface to the crater statistics on Europa's surface. The last observation on this week's schedule is a global observation of Europa performed by NIMS.

    Дата: 27 января 1998 (1998-01-27) От: Alexander Bondugin Тема: NEAR Completes Flawless Earth Swingby Привет всем! Вот, свалилось из Internet... John Hopkins University Press Release Applied Physics Laboratory 23 January 1998 FOR IMMEDIATE RELEASE NEAR COMPLETES FLAWLESS EARTH SWINGBY The Near Earth Asteroid Rendezvous (NEAR) spacecraft flew by the Earth this morning, "right on schedule and right on target," says a jubilant Thomas Coughlin, Space Programs Manager at The Johns Hopkins University Applied Physics Laboratory (APL), which manages the NEAR mission. All spacecraft subsystems worked flawlessly as NEAR swooped around the Earth during a 2-hour visit for a gravity assist that put it onto the correct trajectory for a Jan. 10, 1999, encounter with asteroid 433 Eros. The Jan. 22-23 swingby put the United States on watch for its first naked-eye glimpse of an interplanetary spacecraft. The southern states from east to west, and especially Hawaii, got the best view because of clear skies and darkness that made it easier to see sunglints off the spacecraft's four solar panels. Although closest-encounter data is still being processed, early indications are that NEAR passed within 336 miles of southwest Iran, as predicted. (Encounter data will be posted on the NEAR Web page as soon as it is available.) The first sighting of NEAR was made at about 1:30 p.m. EST, by an astronomer in Caussols, France, using a 0.9 meter telescope, as the spacecraft approached far above the Middle East. When sighted, NEAR was 580,000 miles from Earth and within a half-mile of its expected location. Data captured by NEAR instruments will start coming in to the APL Mission Operations Center in Laurel, Md., about 8 p.m., this evening, says Mark Holdridge, Mission Operations Director, and scientists expect to release the first images from the swingby on Monday, Jan. 26. Today NEAR is taking a series of images of Asia, Africa and Antarctica as it pulls away from Earth. The images will be combined to make a "movie" documenting the spacecraft's visit. For the next week NEAR's Multi-Spectral Imager and its Near-Infrared Spectrograph will be calibrated using proven measurements of Earth and moon geological features. On Feb. 6 the last of the instruments will be turned off. Over the next year as NEAR closes in on Eros scientists and engineers will be developing and testing flight and ground software for the spacecraft and finalizing procedures for the yearlong encounter with the asteroid. NEAR's study of Eros will be the first in-depth examination of a near-Earth asteroid and is expected to yield information that will help scientists better understand the evolution of our solar system. NEAR, which is being tracked by NASA's Deep Space Network, is the first mission in the Space Agency's Discovery series. --------------------------------------------------------- For more information contact Helen Worth, JHU/APL Office of Public Affairs.

    Дата: 27 января 1998 (1998-01-27) От: Alexander Bondugin Тема: NASA Comet and Jupiter Missions Offer Educator Fellowships 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: Mary Beth Murrill or Jane Platt January 22, 1998 NASA COMET AND JUPITER MISSIONS OFFER EDUCATOR FELLOWSHIPS Two NASA space missions are seeking candidates to apply for educator fellowships to help field-test educational modules and to plan and participate in teacher training workshops developed by the projects. NASA's Stardust mission, which will launch in 1999, fly to a comet and collect a sample for return to Earth, is seeking applicants for 10 educator fellowships. As part of a nationwide teacher training initiative, the Stardust project is developing educational modules, targeted at grades 4 through 8, that will be tested by the Stardust Educator Fellows chosen from around the country. In late spring/summer 1998, a second announcement of opportunity will be distributed to solicit candidates from which an additional 15 Stardust Educator Fellows will be selected and trained in fall 1998. Those selected for the educator fellowships will receive an all-expenses-paid intensive training workshop about the comet sample return mission this spring at Lockheed Martin Astronautics in Denver, CO. Fellows will also receive guidance on presentation strategies and a complete teacher training presenter package so they can conduct their own Stardust teacher training workshops. Ideal candidates are actively teaching or conducting teacher training in a formal or informal science environment (school district, science center, museum, educational organization, etc.). Selected candidates will be announced by March 6, 1998. Additional information for Stardust Educator Fellowship applicants is available on the Stardust home page at http://stardust.jpl.nasa.gov Candidates are also being sought for the Galileo Europa Mission Educator Fellowship Program for 1998 and 1999. A team of 15 Educator Fellows will be selected for training at the Jet Propulsion Laboratory, Pasadena, CA. Individuals selected will receive a complete workshop package and educational materials to conduct their own teacher training geared toward middle and high school teachers. More information is available at http://www.jpl.nasa.gov/galileo/ The fellowships will focus on the Galileo Europa Mission, a two-year extension of the Galileo Mission to Jupiter, which will study two of Jupiter's moons with opposite and extreme conditions. Icy Europa may have liquid oceans hidden under its surface, while Io is dotted with volcanoes. Applications for the Galileo Europa Mission Educator Fellowships must be received by Feb. 16, with selected candidates to be announced on Feb. 27.

    Дата: 27 января 1998 (1998-01-27) От: Alexander Bondugin Тема: * SpaceNews 26-Jan-98 * Привет всем! Вот, свалилось из Internet... SB NEWS @ AMSAT $SPC0126 * SpaceNews 26-Jan-98 * BID: $SPC0126 ========= SpaceNews ========= MONDAY JANUARY 26, 1998 SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is published every week and is made available for non-commercial use. * InfoEspace NEWS * Mike, VE2TRV, has made some adjustments to the Laval Laurentides ARC Web site, so InfoEspace, the French translation of SpaceNews, has been moved to its own subdirectory. The number of files in the /ve2crl directory was becoming too large to manage efficiently. The latest edition of InfoEspace is now at the following URL: http://pages.infinit.net/ve2crl/infoesp/space.htm Work is currently underway to have archives of InfoEspace available at the site. The download page will be accessible via a link on the main InfoEspace page, and the files will be compressed using PKZIP. The changes should be completed by the end of January. InfoEspace is in its fourth year of publication, serving French-speaking amateur space fans since mid-1994. [Info via Mike Detaille, VE2TRV] * FUJI-OSCAR-29 NEWS * A memory error was detected in the onboard computer system of the FUJI-3 (FO-29) satellite. Restarting and software reloading is currently being carried out, but the process is taking a long time due to poor uplink efficiency. The operating schedule previously announced for FO-29 has been cancelled. The satellite will remain in analog mode (Mode JA) continuously untuil further notice. A new operating schedule is expected to be announced shortly. [Info via Kazu Sakamoto, JJ1WTK] * AMSAT-OSCAR-10 WOBBLE * Recent observations suggest that the AMSAT-OSCAR-10 satellite is no longer stable in its Z-axis (the normal axis of spin), and is slowly tumbling or "wobbling" in orbit. The satellite is currently going through several deep periods of signal fading with a measured cycle of 15 to 20 minutes, and this condition will make it difficult, if not impossible, for spacecraft controllers to accurately predict AO-10's functional status over long periods of time. If the present trend continues, AMSAT-OSCAR-10 will simply continue to show periods of slow signal fading followed by periods of rather strong signals over a cycle of multiple minutes as a result of the Z-axis wobble. [Info via Stacey Mills, W4SM] * TEACHER SELECTED FOR ASTRONAUT CORPS * NASA has selected Barbara Morgan, an elementary school teacher from McCall, ID, to join the next astronaut candidate class as a mission specialist, and she has accepted. In a decision that re-emphasizes the importance of NASA's strong commitment to education and its unique position to advance the Nation's goals to improve science, mathematics, and technology education, the Agency has determined that it is appropriate to include educator mission specialists in the astronaut corps. In addition to meeting the astronaut selection requirements, mission specialists with education and teaching backgrounds in science, mathematics and technology will be selected and trained in the astronaut corps. These mission specialists will carry out educational programs in addition to their other assigned flight duties. [Info via NASA] * MIR AMATEUR RADIO STATUS * The Sputnik-40 Amateur Radio Satellite went silent around December 30, 1997. The satellites batteries lasted 4 weeks longer than expected. Overall, the project was a complete success. It generated lots of interest in space and satellites around the world. School children everywhere were tuning their radios to listen for the beep, beep, beep of Sputnik-40. Congratulations go to everyone involved in the Sputnik project. Those fortunate enough to hear the signal from Sputnik before it went silent can send away for a SWL (Short Wave Listener) card from one of two addresses. Listeners who heard the satellite on more than one occasion should only send away for ONE (1) card. In an earlier report, an incorrect zip code and old city name name were included in a QSL address. The good news is that people who used the old address do not have to worry. Most of the cards addressed to the old address are being delivered to the correct address. Include with your card the date and UTC time the signal from Sputnik-40 was copied. Envelopes should be well sealed and not include cash. Send an SAE (Self Addressed Envelope) and one or two IRC coupons (which can be purchased at major US post offices) with your request. Do not make any notes on the out side of the envelope with Amateur Radio call signs visible. Dave Larsen, MIREX / N6CO is not handling SWL cards for Sputnik. Please use the address below. QSL Information for SWL (Short Wave Listener) Sergej Samburov PO Box 73 Korolev-10 City Moscow Area, 141070, Russia There is another address that can be used to receiver confirmation of Sputnik-40 reception is the FR5KJ radio club: FR5KJ radio club College Jules Reydellet 103 rue de la Republique 97 489 Saint Denis Cedex Reunion Island. The Mir crew is expected to be very busy for the next two months. The 2-meter packet radio station was temporarily moved from the core module of Mir and installed in the Priroda Module. This move was performed to take advantage of the backup tri-band antenna shared with the SAFEX II repeater. The crew also installed a TNC recently, but due to the crew's heavy work load, the TNC parameters have not been properly configured. Mirex would like stations monitoring the PMS to please be patient while adjustments are made. The PMS is NOT fully operational at this time. MIREX has created an Internet Web page containing information regarding Mir and the various Amateur Radio experiments taking place from the space station. The pages are still "under construction", but some good information can be gathered from what has been put together so far.

    Дата: 27 января 1998 (1998-01-27) От: Alexander Bondugin Тема: Lunar Prospector Update - January 25, 1998 Привет всем! Вот, свалилось из Internet... Lunar Prospector Mission Status Report #14 January 25, 1998 - 12:00 noon EST (9:00 a.m. PST) The Lunar Prospector Mission Control Center at NASA's Ames Research Center has announced that, as of 4 p.m. PST (7 p.m. EST) on Fri., Jan. 23, 1998, the spacecraft and its science instruments continue to operate well, and at the expected nominal levels. The current statistics regarding the spacecraft, its instuments and mission, as reported by Mission Operations Manager Marcie Smith (at 0000 GMT [Zulu] on Saturday, 1/24/98; 4 p.m. PST on 1/23/98), are as follows: Orbit Number: 137 Data Downlink Rate: 3600 bps Spacecraft Spin Rate: 12.09 rpm Spin Axis Attitude: Longitude: 226 deg Latitude: 88.1 deg Trajectory: Periselene: 90 km Aposelene: 110 km Period: 118 minutes duration Occultations: 35 minutes duration Eclipses: 15 minutes duration A total of 72 commands were sent to the Lunar Prospector spacecraft on Thursday night and Friday to set the gains for the Magnetometer and Electron Reflectrometer (MAG and ER) science instruments, and to move the downlink to the medium gain antenna from the Omni antenna (used to date). This served to increase the signal level by about 7 dB, improving the data return at the receiving ground stations. In the way of upcoming events, a small spin axis attitude reorientation maneuver will be executed, during day shift on Monday, Jan. 26, followed by a spin trim.

    Дата: 27 января 1998 (1998-01-27) От: Alexander Bondugin Тема: Ball Aerospace To Provide ICESAT Spacecraft Привет всем! Вот, свалилось из Internet... Douglas Isbell Headquarters, Washington, DC January 26, 1998 (Phone: 202/358-1753) Tammy Jones Goddard Space Flight Center, Greenbelt, MD (Phone: 301/286-5566) RELEASE: C98-a BALL AEROSPACE TO PROVIDE ICESAT SPACECRAFT Ball Aerospace and Technologies Corp., Boulder, CO, has been selected to provide the spacecraft for the Laser Altimetry Mission scheduled to be launched in a near-polar orbit in July 2001. Total cost of the mission is set at under $200 million, including the launch vehicle and three years of science and data analysis. Total value of Ball Aerospace's delivery order will be announced after the contract is finalized and awarded in early February. The Laser Altimetry Mission, recently known as ICESAT for Ice, Cloud and land Elevation Satellite, will accurately measure the elevations of the Earth's ice sheets, clouds, and land and answer fundamental questions about the growth or shrinkage of the Earth's polar ice sheets and future global sea level rise or fall. ICESAT also will measure the heights of clouds for studies of Earth's temperature balance and will measure land topography for a variety of scientific and potential commercial applications. In addition to providing the spacecraft, Ball Aerospace will integrate and test the primary instrument on the ICESAT satellite, the Geoscience Laser Altimeter System. The laser altimeter is being developed at NASA's Goddard Space Flight Center, Greenbelt, MD, and will provide precise elevation of the land, ice, and clouds that are overflown. The laser is completely eye-safe to individuals on the ground. It works by transmitting short pulses of infrared light and visible-green light to measure ice sheet elevation and land topography (infrared light) and measurements of clouds and aerosols (green light). The distance from the spacecraft to clouds and to Earth's surface will be determined from measurements of the time taken for the laser pulses to travel to these targets and return. Similar instrumentation has been flown on aircraft over the Greenland ice sheet for proof-of-concept experiments. The Greenland and Antarctic ice sheets cover 10 percent of the Earth's land area, and contain 77 percent of the Earth's fresh water and 99 percent of its glacier ice. Measurements of the ice sheets are essential for assessing whether future changes in ice volume will add to the sea level rise, which is already occurring, or whether the ice sheets might grow and absorb a significant part of the predicted sea level rise. ICESAT is one in a series of spacecraft for NASA's Earth Science program which will study the Earth's system and the effects of natural and human-induced changes on the global environment. ICESAT is being developed by a partnership of NASA, industry, and university teams. ICESAT will be placed into an orbit 379 miles above the Earth with an inclination of 94 degrees to the equator. A launch vehicle for the ICESAT mission will be selected from the stable of medium-light expendable launch vehicles. ICESAT's designed lifetime is for three years of operation with a five-year goal. Ball Aerospace's selection was made through an innovative procurement program developed at NASA to procure, build, and deliver spacecraft faster and more cheaply than ever before. The Indefinite Delivery/Indefinite Quantity contract will make it possible to go from procurement to launch in less than four years. The ICESAT mission and the development of the laser altimeter instrument will be managed by Goddard for NASA's Earth Science enterprise.
