STS-99, Mission Control Center
Status Report # 04 Saturday, February
12, 2000 - 6:00 p.m. CST
By the time members of Endeavour’s
Red Team had reached lunchtime on this first full day in space for the
Shuttle Radar Topography Mission, the radar antennas in the payload
bay and at the end of a 200-foot mast had mapped about 1.7 million square
miles (4.5 million square kilometers) of the Earth’s surface, or
the equivalent of about half the area of the United States.
The Red Team – Kevin Kregel,
Janet Kavandi and Gerhard Thiele – took over the mapping operations
from their Blue Team counterparts shortly after waking up about 7 this
morning Central Time. Dom Gorie, Janice Voss and Mamoru Mohri turned
in shortly after 2 this afternoon and are to be awakened at 10:14 tonight.
For a few minutes this morning – while Japanese astronaut Mohri
conducted mapping operations – Gorie and Voss discussed the mission
with CNN and NBC’s Today Show.
The crew is working around
the clock, in two shifts, to collect data that will produce maps of
the Earth with unprecedented accuracy and uniformity. Mapping operations
will continue for 10 days, and are proceeding very smoothly. SRTM will
cover the area between 60 degrees north and 56 degrees south, roughly
the area between St. Petersburg, Russia to the north and the tip of
South America to the south. The area to be mapped is home to about 95
percent of the Earth’s population. In all, more than 70 percent
of the Earth’s surface will be mapped.
The first X-band image –
of the area near White Sands, New Mexico – was released this afternoon,
and scientists expressed their delight with the quality of the image.
X-band images will be posted to the German Space Agency web site at
www.dfd.dlr.de/srtm/html/newtoday_en.htm. Both the C-band and X-band
radars continue to perform as expected.
“The data we’ve seen
so far looks just terrific,” said Dr. Michael Kobrick, project
scientist at NASA’s Jet Propulsion Laboratory in Pasadena, CA.
“The mapping plan is right on schedule.”
Early this afternoon, Kregel
fired the shuttle’s thruster jets in a series of pulsed burns to
measure the movement of the rigid mast extending over Endeavour’s
left wing. Flight controllers reported the tip of the mast moved only
11 inches, just as predicted, despite the fact the antenna’s dampers
remained locked in position. The firings were necessary to determine
how they affect the mast, prior to upcoming maneuvers to raise Endeavour’s
orbit.
Endeavour’s crew also
downlinked launch video from an in-cabin camera, providing a unique
perspective of yesterday’s flawless launch.
All of Endeavour’s payload
and spacecraft systems are continuing to function normally.
The next mission status report
will be issued at 6 a.m. Sunday, or as events warrant.
