STS-108 Day 11 Highlights
Back to STS-108 Flight Day 10 Highlights:
- On Saturday, December 15, 2001, 5:30 a.m. CST, STS-108 MCC Status Report # 20
- 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^Òs departure from the complex.
- Endeavour is bringing home the Expedition Three crew ^Ö Commander
Frank Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail
Tyurin ^Ö 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 ^ÓWhere I Come From,^Ô 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^Òs 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^Òs scheduled reboost, beginning at 8:55 a.m. and
using Endeavour^Òs small firing jets for about 20 minutes, the space
debris is now expected to pass more than 40 miles away from the
- 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^Òs 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^Òs 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.
- On Saturday, December 15, 2001, 6:00 p.m. CST, STS-108 MCC Status Report # 21
- After eight days together, Endeavour and the International Space
Station parted ways today, the shuttle leaving behind a new station
crew and ferrying home a veteran station crew.
- Endeavour undocked from the station at 11:28 a.m. CST as the
spacecraft flew 240 statute miles above the Indian Ocean off the
Australian coast. Pilot Mark Kelly flew Endeavour through a
half-circle of the station before firing jets to leave the vicinity.
- Before undocking, Endeavour's jets were fired in a series of small
pulses beginning at 8:55 a.m. CST to raise the altitude of the station
about three quarters of a mile. The maneuver ensures the station will
fly well clear of an old Russian rocket body that had been predicted
to potentially pass close to the complex later this weekend. The final
small reboost by the shuttle, coupled with three larger reboosts done
earlier in the week, means the station was raised a total of more than
nine statute miles by Endeavour.
- The new station crew, Expedition Four Commander Yury Onufrienko and
Flight Engineers Dan Bursch and Carl Walz, said goodbye to Endeavour's
crew and the departing Expedition Three crew and closed hatches
between the spacecraft at 7:16 a.m. CST. Now en route home, Expedition
Three Commander Frank Culbertson, Pilot Vladimir Dezhurov and Flight
Engineer Mikhail Tyurin completed 117 days as the primary station crew
and spent 125 days aboard the station overall. When Endeavour lands on
Monday, they will have spent a total of 129 days in space.
- The crew members aboard Endeavour had several hours off duty after
departing the station, a break from a very busy pace moving tons of
supplies between the shuttle and station during the past
week. Sunday's activities will focus on checking out systems used
during descent and making preparations for a landing on
Monday. Endeavour is set to land at the Kennedy Space Center. FL,
about 11:28 a.m. CST Monday. The weather forecast predicts generally
acceptable conditions except for a chance of rain showers in the
vicinity of the landing site. Flight controllers determined today that
all three Inertial Measurement Units on Endeavour, the primary
navigation systems for the shuttle, would be usable for landing. One
of the three units had been taken off line two days ago due to a brief
fault. However, the unit has worked well since that time. Even if the
problem were to recur, it would not affect Endeavour's entry and
landing since the shuttle can operate with only one such unit if
necessary. Endeavour's crew will begin a sleep period at 7:19 p.m. CST
and awaken at 3:19 a.m. CST Sunday. The Johnson Space Center newsroom
will open at 5 a.m. CST Sunday, and the next Mission Control status
report will be issued at about 6 a.m. CST Sunday or as events warrant.
