NASA Says Lunar Ice Rumors Wrong
Washington, DC Feb. 10, 1998 - Data being studied from the lunar
orbiting Prospector satellite cannot be quantified as having detected
ice on the Moon, the head of the project's science team told SpaceCast
Monday in an exclusive interview. Dr. Alan Binder, Principal
Investigator for the Lunar Prospector Project, said by telephone from
the Ames Research Center in Mountain View, California that the data is
of unexpectedly high quality - but that analysis has so far proved to be
a non conclusive result. "We're glad people everywhere are interested in
this information, but we can make no conclusive statements yet, even on
a preliminary basis," Binder said.

FOR IMMEDIATE RELEASE February 9, 1998
JPL PRESENTS A SEARCH FOR NEAR-EARTH APPROACHING ASTEROIDS
"Destination Earth: JPL's Near-Earth Asteroid Tracking
Program" will be the theme for two free public lectures, one on
Thursday, Feb. 19 at 7 p.m. in JPL's von Karman Auditorium, the
other on Friday, Feb. 20 at 7 p.m. in The Forum at Pasadena City
College. Seating is limited and will be on a first-come, first-
served basis.
The lecture will be presented by Eleanor Helin, principal
investigator of the Near-Earth Asteroid Tracking (NEAT) program.
Helin has been active in planetary science and astronomy for
nearly 35 years at JPL and Caltech. She initiated the Planet-
Crossing Asteroid Survey from Palomar Observatory in the 1970's,
coordinated the International Near-Earth Asteroid Survey in the
1980's, and now leads the NEAT program.
NEAT is an autonomous celestial observatory located at the
U.S. Air Force's Ground-based Electro-Optical Deep Space
Surveillance site on Mt. Haleakala, Maui, Hawaii. It is designed
to complete a comprehensive search of the sky for near-Earth
asteroids and comets.
Since beginning operation in December 1995, NEAT has
discovered more than 15,000 objects, including 26 near-Earth
asteroids, two long-period comets and the very unique object
temporarily numbered 1996 PW, the most eccentric asteroid yet
known.
NEAT is the first autonomous observing program of its type.
No JPL personnel are required to operate the telescope on site in
Hawaii. A Sun Sparc computer runs the observing system through
the night and transmits the data back to JPL each morning.
This lecture is part of the von Karman Lecture Series
sponsored monthly by the JPL Media Relations Office. A web site
on the lecture series is located at
http://www.jpl.nasa.gov/lecture. For information call the JPL
Media Relations Office at (818) 354-5011.

Lunar Prospector Status Report #18
Feburary 9, 1998 - 12:00 noon EST (3:00 p.m. PST)
The Lunar Prospector Mission Control Center at
NASA's Ames Research Center reported that, as of
8:21 p.m. (PST) on Sat., Jan. 31, 1998, the
spacecraft continues to operate well. The past
weekend, a minor glitch with the spectrometer
instrument electronics occurred, in which the
incoming data stream for the vehicle's three
spectrometers was temporarily halted. Mission
controllers decided to power the spectrometer
electronics subsystem on and off, which corrected
the problem. All instruments were reconfigured and
reported to be operating properly. A total of 38
commands were communicated to the spacecraft to
resolve this situation.
Current statistics regarding the spacecraft and its
instruments, as reported by Mission Operations
Manager Marcie Smith (at 10:00 a.m. (PST) on Feb.
2, 1998) are as follows:
Orbit Number: 256
Data Downlink Rate: 3600 bps
Spacecraft Spin Rate: 11.94 rpm
Spin Axis Attitude: Longitude: 251 deg
Latitude: 89.2 deg
Trajectory: Periselene: 96 km
Aposelene: 104 km
Period: 118 minutes duration
Occultations: 46 minutes duration
Eclipses: 32 minutes duration

VIDEO ADVISORY February 10, 1998
IMAGES OF MARS '98 LANDING ZONE REVEAL STRANGE NEW TERRAIN
New images of the Mars '98 landing zone, located in the
frigid south polar region of Mars, will air Wednesday, Feb. 11 on
NASA TV. The images reveal the first close-up views of this
strange, layered terrain, which will become the site of NASA's
1998 Mars Polar Lander mission.
Ground fog obscures the surface in the raw images, shown on
the left of the screen, while image-processing techniques, shown
on the right of the screen, expose ground features in great
detail. The images show an array of light and dark mottled
patterns, and swirling bands of eroded, layered rock reminiscent
of the edges of Alaskan ice sheets. Also included in the NASA TV
file is animation of the 1998 lander mission, footage of payload
testing at JPL and payload integration at Lockheed Martin
Astronautics, Denver, and brief interviews with JPL project
representatives.
The Mars Polar Lander is one of two spacecraft to be
launched to Mars in late 1998 and early 1999 to continue NASA's
program of robotic exploration of the red planet. The 1998
lander will touch down in the southern polar region of Mars in
December 1999 and begin a three-month surface mission to dig for
traces of subsurface water. Meanwhile, its sister ship, the Mars
Climate Orbiter, will begin a two-year mapping mission to profile
the Martian atmosphere and map the surface.
NASA TV is available on GE-2, transponder 9C at 85 degrees
west longitude, vertical polarization, with a frequency of 3880
MHz, and audio of 6.8 MHz. Video news files air at 9 a.m., 12:00
noon, 3 p.m. and 6 p.m. Pacific time.
