STS-106, Mission Control Center
Status Report # 04 Saturday,
September 9, 2000 - 7:00 p.m. CDT
STS-106 Mission
Commander Terry Wilcutt along with his crew, Pilot Scott Altman and
Mission Specialists Ed Lu, Rick Mastracchio, Dan Burbank, Yuri Malenchenko
and Boris Morukov, were awakened at 5:46 p.m. CDT today. The wake up
song from Mission Control was " I Say a Little Prayer" which
was played for Wilcutt. All seven astronauts are now busy with final
preparations for the docking with the International Space Station set
for early tomorrow morning. Atlantis is planned to make the third docking
with the station at 12:52 a.m.
As of about 6:30
p.m. this evening, the Shuttle trailed the station by about 230 statute
miles and was closing in by about 184 miles with each 90-minute orbit
of Earth. The final phase of rendezvous will begin when Atlantis reaches
a point about eight nautical miles directly behind the station and fires
its engines in a terminal phase initiation burn just before 10 p.m.
Central.
The TI burn, as
it is called, will put the Shuttle on a course directly toward the station
during the next orbit of Earth. As Atlantis moves within about a half-mile
of the station, Wilcutt will take over manual control of the Shuttle’s
approach, flying the Shuttle from controls in the aft cockpit. Atlantis
will arrive at a point about 600 feet directly below the station about
11:28 p.m. Central, and Wilcutt then will begin a half-circle of the
orbiting outpost. Atlantis will pass about 350 feet in front of the
station and then move to a point about 250 feet directly above it about
11:55 p.m. Central.
Wilcutt will then
begin to descend toward the station and, just before midnight Central,
hold position at a point about 170 feet away. Wilcutt will maintain
that distance for about 20 minutes to allow the station to move within
range of Russian ground communications stations before continuing the
approach. At 12:41 a.m., Wilcutt will hold position again briefly at
a point about 30 feet from the station to verify the Shuttle and station
docking mechanisms are precisely aligned. Docking is expected about
11 minutes later with the Shuttle contacting the station at a slow rate
of about a tenth of a foot per second. At the time of docking, the ISS
and Atlantis will be at 49.6 degrees North Latitude, 57.1 degrees East
Longitude as they fly over Western Kazakhstan.
During the rendezvous,
Altman will assist Wilcutt in controlling Atlantis' approach. Mastracchio
and Malenchenko also will assist with the rendezvous and docking, with
Burbank and Lu operating the Shuttle’s docking mechanism.
Once docked the
astronauts and cosmonauts will briefly open the hatch between Atlantis
and the mating adapter on ISS to gather an air sample. The hatch will
then be closed in preparation for Monday morning’s planned 6½-hour
space walk by Lu and Malenchenko.
Near the end of
their work day, Atlantis’s crew will get 4 hours of off duty time
to relax before beginning a planned eight hour sleep period at 10:46
a.m. on Sunday.
The next mission
status report will be issued about 7 a.m. on Sunday.
