SPECIAL REPORT: BEHIND THE SCENES FOR PATHFINDER'S LANDING ON MARS

PART 1: First weather data in 26 minutes
PART 2: Subscribing/unsubscribing: how to do it


[Editor's note: Jim Murphy is a scientist who develops numerical computer models of the Martian atmosphere. These computer models are very similar to the computer models used for forecasting weather here on Earth.]

FIRST WEATHER DATA IN 26 MINUTES
Jim Murphy

http://quest.arc.nasa.gov/mars/team/murphy.html

July 4
I'm sitting here at the Jet Propulsion Lab at 1:39 PM PDT,
three-and-one-half hours after Pathfinder successfully landed on Mars
 (which is just
way cool to think about !!!), and I'm waiting for our first surface
meteorology data, which we should receive in 26 minutes. This has been
an absolutely terrific day for the spacecraft, and all of us who are
interested in its success. The entry, descent, and landing apparently
went just as designed (at least, that is the present indication), and
we have a functioning spacecraft on the surface.

We'll receive three minutes of surface weather data, obtained at 7 AM
local time at the landing site, during the low-gain data downlink which
will begin in 24 minutes.  We'll get a temperature measurement a few
centimeters above a solar panel (our mast will not 'stand up'
until 11 AM local time at the landing site. We'll also measure
pressure during this session. We won't measure wind until our
mast is deployed.

It is a great day!!! We really do appreciate all the encouragement
and good wishes we have received from all of you !!!
