STS-102, Mission
Control Center
Status Report # 04
Friday, March 9, 2001 - 7 p.m. CST
With the International
Space Station 300 miles ahead, the crew of the Space Shuttle Discovery
awoke this afternoon to begin a third day in space, a day that will
bring a new crew to the growing International Space Station.
The shuttle crew
was awakened with the Russian song “Vashe Blagorodiye,” a
song from a movie entitled “White Sun of the Desert” that
is traditionally watched by cosmonauts the night before a launch from
the Baikonur Cosmodrome in Kazakhstan. The song was played for Expedition
Two Commander Yury Usachev, who is spending his last day aboard Discovery
before beginning a handover of station command with Expedition One crewmember
Yuri Gidzenko.
All activities
are on track for a docking of Discovery to the station at 11:34 p.m.
The final phase of Discovery’s rendezvous with the station was
to begin with a Terminal Initiation (TI) engine firing by the shuttle
at 9:13 p.m. with Discovery about 50,000 feet behind the station. The
TI burn puts the shuttle on course to intercept the station during the
next orbit of Earth. At about 10:30 p.m., as Discovery reaches a point
about a half-mile below the complex, Commander Jim Wetherbee will take
over manual control of the approach. Wetherbee will fly Discovery to
a position about 300 feet in front of the station, then move in toward
a docking port attached to the end of the station’s Destiny Laboratory.
During the docking,
Pilot Jim Kelly will help control Discovery's approach as astronauts
Andy Thomas and Paul Richards manage the shuttle's docking mechanism
and rendezvous tools. Using a view from a camera mounted in the center
of Discovery's docking mechanism, Wetherbee will center the docking
ports of the two spacecraft precisely, double-checking the alignment
30 feet out. The final approach will be at a relative velocity of one-tenth
of a foot per second.
When Discovery
makes contact with the station’s docking port on Destiny, latches
will automatically connect the two spacecraft as they fly high off the
east coast of Brazil. Once relative motion between the spacecraft stops,
Thomas will retract the docking ring on Discovery's mechanism, closing
latches to firmly secure the shuttle to the station. The hatches between
the shuttle and station are to be opened about two hours later at 1:42
a.m. Saturday.
The crew will begin
transferring crews, equipment and supplies immediately. The first crew
exchange is planned to allow Usachev to be aboard the station jointly
with Expedition One Commander Bill Shepherd for as long as possible
to facilitate the change of leadership. The hatches will be closed again
at 4:37 a.m. Saturday so the shuttle crew can prepare for the first
of two planned spacewalks, a sojourn by astronauts Jim Voss and Susan
Helms set to begin Saturday evening.
The stage is set
for the eighth shuttle docking to the ISS with both spacecraft in good
shape. The next status report will be issued Saturday morning.
