THIS WEEK'S WEB CHAT WITH DAVID MITTMAN

Tuesday, November 18, 1997, 10:30-11:30 a.m., PST
David Mittman has worn three hats during the Pathfinder mission: flight
engineer, mission planner and flight controller. David will bring us up to
date on the operations of the lander and rover, what the commands to
Pathfinder consist of (specific tasks such as "Call Home!"), and the Deep
Space Network's role now that Pathfinder isn't communicating.

Please be sure to read David's biography and journals BEFORE the chat so
that intelligent questions can be asked! We are extremely grateful for the
time the experts can give us and we want to make this a worthwhile
experience for them also!

To read David's bio and journals go to:

RSVP to sandy@quest.arc.nasa.gov

NEW NASA PROGRAMMING

Perhaps you've heard whispers of the new Learning Technologies Channel
(LTC). There are a lot of interesting, real-time events happening. Take a
virtual tour of NASA's practice space stations. Join Tel*Ed Conference
attendees in Texas and Mexico City. Sit in on a U.S. Department of
Education's Satellite Town Meeting!

In addition to this new online programming is a weekly series called
Sharing NASA 101. These presentations feature a Quest Project team member
and a teacher discussing an online learning and teaching tool. This week's
topic was Web chats, next week collaborative online projects will be
presented.

Visit the Web site at: http://quest.arc.nasa.gov/ltc or sign up for the
maillist by sending email to: listmanager@quest.arc.nasa.gov

MISS LAST PATHFINDER PRESS CONFERENCE?

Listen to what is quite possibly the last Mars Pathfinder press conference
at: http://quest.arc.nasa.gov/mars/video/news/mpf.html

Here you will find a RealAudio archive of the November 4 briefing at the
Jet Propulsion Laboratory, including three great video clips narrated by
the IMP camera designer Pete Smith. Check it out!



MARS GLOBAL SURVEYOR FLIGHT STATUS REPORT

[Editor's note: Status report prepared by Office of the Flight Operations
Manager, Mars Surveyor Operations Project, NASA Jet Propulsion Laboratory]

Friday, November 7, 1997

A mission milestone was reached today as the flight team celebrated the
one-year anniversary of the launch of Mars Global Surveyor. During the
previous year in flight, the spacecraft has completed a 10-month,
435-million-mile (700-million-kilometer) journey to reach Mars, followed
by 36 revolutions around the planet.

Science results to date have included photographs of gigantic volcanoes
and canyons, the discovery of local magnetic fields, topography
measurements throughout the northern hemisphere, and thermal measurements
of the atmosphere and surface. Some of the latest scientific observations
will be presented at a press conference on Monday, November 10 at 10:00
a.m. PST. Material from the conference will be available for download from
the Surveyor Web site early next week.

Today also marked the return to aerobraking operations after a one- month
hiatus. At 1:51 p.m. PST, the onboard flight computer commanded Surveyor's
tiny thruster rockets to fire for 50 seconds. This burn occurred at the
high point of the 36th orbit around Mars and slowed the spacecraft by 4.3
miles per hour (1.9 meters per second). As a consequence, the low point of
the orbit was dropped from its current altitude of 109.1 miles (175.6
kilometers) down to 83.7 miles (134.8 kilometers).

When Surveyor reaches the new low point of the orbit early Saturday
morning, it will skim through the upper Martian atmosphere for about 300
seconds. During this aerobraking pass, the air resistance pressure
experienced by the spacecraft's solar panels will be 12 times less than
that proposed by the original mission plan. Over the next week, the flight
team will gradually increase the amount of atmospheric pressure
experienced during aerobraking by further lowering the orbit's low point.

After a mission-elapsed time of 365 days from launch, Surveyor is 181.16
million miles (291.55 million kilometers) from the Earth and in an orbit
around Mars with a high point of 28,016 miles (45,088 km), a low point of
83.7 miles (134.8 km), and a period of 35.4 hours. The spacecraft is
currently executing the P37 command sequence, and all systems continue to
perform as expected.
