STS-99, Mission Control Center
Status Report # 14 Thursday, February
17, 2000 - 6 p.m. CST
Propellant conservation measures
have paid off and Endeavour’s crew was notified this morning that
the mapping operations will continue for the full nine days as planned
prior to launch. “That’s great news,” replied Pilot Dom
Gorie. “They’re getting some fantastic data on this mission.”
As of noon today, 81 percent,
or more than 39 million square miles of the target area had been mapped
once. That exceeds the land area of the Americas, Africa and Australia
combined. More than 47 percent of the target area – over 22 million
square miles – has been mapped with two or more passes. Endeavour
images 40,000 square miles of land every minute.
Astronaut Chris Hadfield in
Mission Control transmitted the good news to the crew aboard Endeavour
while all six astronauts were awake conducting a shift change. The crew
is working around the clock on two shifts conducting the detailed mapping
operations. Several fuel-saving steps have been implemented, including
a change in the way excess water is dumped overboard, and allowing more
flexibility in holding Endeavour and the 200-foot mast in the proper
attitude. The final conservation measure will be the deletion of the
eighth trim burn, which controllers believe can safely be deleted by
adjusting the sixth and seventh burns without a disruption to data collection.
Exuberant scientists today
released new radar images of the San Andreas Fault in California, the
Los Angeles basin, Southern California’s San Gabriel Mountains,
and the island of Hokkaido, Japan, birthplace of Mission Specialist
Mamoru Mohri. “We’re well on the way to making the best topographic
map of the world ever,” said Dr. Diane Evans, chief scientist in
the Jet Propulsion Laboratory’s Earth Science Office. “We
are ecstatic about this data set.” She said the level of detail
in maps resulting from this Shuttle Radar Topography Mission should
help scientists better understand earthquakes and mudflows.
Science operations continued
through the seventh day of the mission, with trouble-shooting a problem
with one of six high data-rate recorders on board being the only issue
of significance. The recorders are used to capture the masses of data
collected during the SRTM mission on 270 tapes.
Earlier today, Mohri spoke
about the mission with Japanese Prime Minister Keizo Obuchi and the
Minister of State for Science and Technology. Later, he joined Dom Gorie
and Janice Voss for interviews with The Weather Channel and two television
stations. Janet Kavandi briefly joined them to send greetings to her
hometown of Springfield, MO.
Meanwhile, EarthKam continues
its record-breaking production of images, having processed 1,355 images.
The project allows school students to remotely take pictures of the
Earth using a camera mounted in one of Endeavour’s windows.
The orbiter continues to perform
smoothly and provide a solid platform for the most accurate and unified
topographical mapping of the Earth ever produced. The next status report
will be issued at 6 a.m. Friday, or as mission events warrant.
