AEROSPACE SAFETY ADVISORY PANEL TO PRESENT REPORT TO NASA
The Aerospace Safety Advisory Panel (ASAP) will present its
annual report at a public meeting to NASA Administrator Daniel S.
Goldin at 1 p.m. EST on Thursday, Feb. 12, 1998, in the Program
Review Center, room 9H40, NASA
Headquarters, 300 E Street S.W., Washington, DC.
Each year, the panel reviews and evaluates current and future
NASA programs and activities and reports its findings to the NASA
Administrator. Priority is given to programs that involve the
safety of human flight.
Following the Apollo spacecraft fire on Jan. 27, 1967,
Congress enacted legislation to establish the ASAP as a senior
advisory committee to NASA.
The ASAP report will be available for media representatives
at 1 p.m. Thursday in the NASA Headquarters Newsroom (202/358-
1600). The report will be distributed at the meeting and is on
the Code Q home page at URL:

RELEASE: 98-27
FIRST MAJOR FLIGHT COMPONENT FOR X-33 ARRIVES AT PALMDALE
NASA and Lockheed Martin Tuesday saw their X-33 technology
demonstrator move from drawing board to plant floor as the first
major flight component arrived at the Lockheed Martin Skunk Works
vehicle assembly facility in Palmdale, CA.
The 26-foot-long, 5,500-pound aluminum liquid oxygen tank
that will form much of the nose and forward third of the X-33
vehicle arrived Tuesday afternoon by air from the Lockheed Martin
Michoud Space Systems facility, New Orleans, LA.
"The arrival of the liquid oxygen tank marks the start of an
ambitious assembly schedule that will see the X-33 vehicle roll
out and begin flight tests within 18 months," said Jerry Rising,
Lockheed Martin Skunk Works vice president for X-33/VentureStar.
"This is a significant achievement in making the X-33 vehicle
ready for flight, as the liquid oxygen tank is the first major
element to be placed into the assembly fixture," added Gene
Austin, NASA X-33 program manager.
The tank, designed to hold more than 181,000 pounds of liquid
oxygen, will supply the oxidizer needed to burn the vehicle's
fuel, liquid hydrogen.
The liquid oxygen tank design also plays a key structural
role in the X-33. It has a complex, two-lobed structure allowing
for a close fit within the vehicle's outer shell. When filled,
the tank will account for about 65 percent of total vehicle weight
at liftoff.
The liquid oxygen tank design is one of a number of
challenging technology areas that are key to the X-33, including
the vehicle's two cutting-edge composite liquid hydrogen tanks,
two linear aerospike engines, the vehicle's rugged metallic
thermal protection system and advanced avionics systems, all of
which will be arriving at the Palmdale facility during the coming
year. Vehicle assembly is scheduled to be completed in late
spring 1999, with the first flight, to be launched from Edwards
Air Force Base, CA, scheduled for July 1999.
The wedge-shaped X-33 is a sub-scale prototype technology
demonstrator leading to the next generation of commercially
developed and operated single-stage-to orbit vehicles, flying
after the turn of the Century, which could dramatically reduce the
cost of putting payloads into space.

Тема: Lunar Prospector Update #2 - February 9, 1998
Привет всем!

Lunar Prospector Status Report #19
Feburary 9, 1998 - 7:00 p.m. EST (4:00 p.m. PST)
This past week, no anomalies surfaced with regard
to the spacecraft or its instruments, and no
commanding activities were performed. During the
afternoon (PST), Feb. 9, 1998, Mission Control
executed a small re-orientiation maneuver.
According to mission controllers at Ames, thermal
constraints made this maneuver necessary to
re-position the orientation of the spacecraft's
spin axis so that the Sun angle is pointing
slightly toward the top of the vehicle.
The Lunar Prospector spacecraft continues to
perform very well according to Mission Control at
NASA's Ames Research Center. The current state of
the vehicle (as of 4:00 p.m. (PST) on Mon., Feb. 9,
1998), according to Mission Operations Manager
Marcie Smith, is as follows:
Orbit Number: 345
Data Downlink Rate: 3600 bps
Spacecraft Spin Rate: 11.94 rpm
Spin Axis Attitude: Longitude: 242 deg
Latitude: 88.4 deg
Trajectory: Periselene: 92 km
Aposelene: 109 km
Period: 118 minutes duration
Occultations: 46 minutes duration
Inclination: none
Eclipses: 39 minutes duration
