STS-108, Mission Control Center
Status Report # 20
Saturday, Dec. 15, 2001 – 5:30 a.m. CST
The 10 crewmembers
of the Space Shuttle Endeavour and the International Space Station will
bid farewell to each other this morning shortly before the hatches are
closed between the two vehicles about 7:30 a.m. CST prior to Endeavour’s
departure from the complex.
Endeavour is bringing
home the Expedition Three crew – Commander Frank Culbertson, Pilot
Vladimir Dezhurov and Flight Engineer Mikhail Tyurin – who have
been in space since they launched to the station on August 10. In addition
to bringing home the Expedition Three crew, Endeavour carried to orbit
both a new crew and almost three tons of supplies and experiments to
the station. That new crew, Expedition Four Commander Yury Onufrienko
and Flight Engineers Dan Bursch and Carl Walz, will remain aboard the
space station until May.
The Endeavour astronauts
were awakened for their 11th day in space at 4:17 a.m. by the song “Where
I Come From,” by Alan Jackson, for Pilot Mark Kelly from his family.
Overnight, flight
controllers decided to execute an additional reboost of the space station,
designed to add about three-quarters of a mile to the station’s
altitude. On Friday, flight controllers received word from U.S. Space
Command that a spent Russian rocket upper stage, launched in the 1970s,
could pass within three miles of the station. With today’s scheduled
reboost, beginning at 8:55 a.m. and using Endeavour’s small firing
jets for about 20 minutes, the space debris is now expected to pass
more than 40 miles away from the station.
With Kelly at the
controls, Endeavour is scheduled to undock from the station about 10:37
a.m., concluding more than a week of docked operations. Because today’s
scheduled reboost will use additional propellant, Endeavour will not
perform a full-circle flyaround of the station after undocking. Instead,
the shuttle will undock from the station, performing a quarter circle
flyaround of the complex to a point about 400 feet directly above the
station where it will fire its engines in a final separation burn at
11:20 a.m. beginning its departure from the orbiting outpost.
On the station,
all systems are functioning well, including a newly refurbished air
conditioning unit in the Russian Zvezda Service Module which received
a new compressor yesterday. The air conditioner was tested last night
and is functioning normally.
The STS-108 and
Expedition Three crewmembers will take time this afternoon to discuss
the progress of their mission with KGO-TV in San Francisco, the Fox
News
Network and Associated
Press in an interview scheduled to begin at 3:09 p.m. today on NASA
TV. The crew also will enjoy several hours of scheduled off duty time
today prior to gearing up for Monday’s scheduled landing.
Homecoming at the
Kennedy Space Center is scheduled at 11:55 a.m. Central time Monday.
The early weather forecast calls for possible scattered and broken clouds
and thunderstorms within 30 nautical miles of the landing strip.
The next Mission
Control Status report will be issued about 6 p.m. CST Saturday or as
events warrant.
