UPCOMING WEBCHATS

- Tuesday, March 4, from 9-10 a.m., PDT, Peter Thomas, Cornell
        University, Ithaca, NY.
- Tuesday, March 11, from 9-10 a.m., PDT, Bridget Landry, Jet
        Propulsion Laboratory, Pasadena, CA

PETER THOMAS is a research scientist at Cornell University in
Ithaca, NY. He studies pictures of other planets and satellites sent
back by spacecraft. His particular interests in Mars are how the
wind shapes the surface by moving sand and dust, sometimes in
global storms, and how the polar caps have affected Mars' geology
and climate.

Peter is a member of the science teams that plan, and will analyze
images sent back by the Mars Orbiter Camera on Mars Global
Surveyor, as well as the Orbiter and Lander cameras on the '98 Mars
Surveyor Orbiter and Lander. He also works on other planetary
missions such as the Near Earth Asteroid Rendezvous Mission, the
Galileo mission to Jupiter, and the Cassini mission to be launched to
Saturn.

BRIDGET LANDRY teaches computers on the ground to speak the same
language as the Mars Pathfinder. As the deputy uplink systems
engineer, Bridget takes very complex, but general computer
programs and makes them understand all the commands that the
Pathfinder knows. The people on the science and instrument teams
then use this tool to build sets of commands called sequences,
which, when sent to the spacecraft, accomplish specific tasks, like
taking pictures, etc.

Please join us! RSVP to Andrea by sending a brief Email note to
andream@quest.arc.nasa.gov. This RSVP is very important, as it will
allow us to ensure that the chatroom does not become too crowded.

DON'T FORGET!

NASA TELEVISION SIGNAL GETS A NEW HOME

[Editor's note: This NASA press release (N97-11) was written by
Deanna Corridon, Headquarters, Washington, DC]

February 25, 1997

On March 15, NASA Television will begin broadcasting via a new
satellite that will allow reception by a wider audience throughout
the continental United States, Alaska and Hawaii. NASA Television is
designed to provide real-time coverage of Agency activities and
missions as well as resource video to the news media, and
educational programming to teachers, students and the general
public.

NTV currently is transmitted on the Spacenet 2 satellite, which is
nearing the end of its life cycle. The GE-2 satellite, which was
launched in January and is operated by GE Americom, will provide
NASA TV with a larger "footprint," or coverage area.

Effective March 15, NTV will be 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.

scheduling, please visit the NASA Television home page on the
