STS-101, Mission Control Center
Status Report # 12
Wednesday, May 24, 2000 - 7 p.m. CDT
STS-101 Commander
Jim Halsell and his crew are continuing their efforts aboard the International
Space Station as they begin their fourth day of docked operations. The
seven astronauts were awakened at 3:28 p.m. CDT with the music, "I'm
Gonna Fly" by Amy Grant which was requested by Pilot Scott Horowitz's
wife.
Halsell, Horowitz
and Mission Specialists Mary Ellen Weber, Jeff Williams, Susan Helms,
Jim Voss and Yury Usachev will spend their third day inside the station
continuing the maintenance work and supply transfer activities that
began Monday evening. During their first two days inside the station,
the astronauts have moved more than a ton (2,049 pounds) of supplies
and equipment inside the facility to be used by the first station crew.
More than 3,000 pounds will be transferred to the station before Atlantis
undocks on Friday evening.
Helms and Usachev
already have completed the replacement of the fourth and final battery.
The second battery replaced on Monday evening is fully recharged and
working well as it supports station operations. The third battery, which
was replaced last night, has begun its 20-hour charging process. All
of the battery work is designed so that at least four of the station's
six batteries are available to support station systems.
Other work on
tap for this evening includes the replacement of a Zarya radio telemetry
system which has reached the end of its design life. The radio telemetry
system collects and stores station data when ground station communications
are not available. The crew also will fill four large water bags and
transfer the bags to the station to join seven similar bags left during
the STS-96 mission last year. The water bags will be part of the potable
water supply used by the first station crew when it arrives later this
year.
Tonight also will
see the second of three planned reboost maneuvers to raise the station's
altitude. The one-hour procedure will involve 27 pulse firings of Atlantis's
maneuvering thrusters. The three reboosts will raise the station to
a new altitude about 237.5 x 227 statue miles and will place the station
in the optimum altitude for the arrival of the Zvezda Service Module
when it is launched in July.
Shuttle and station
managers have decided to move the undocking time to one orbit later.
The new undocking time is now 6:07 p.m. CDT on Friday, May 26th and
will happen while the two spacecraft are over Russian ground stations.
The later undocking will allow the crew to get a full eight-hour sleep
period. Atlantis will make shortened fly around, one half revolution
of the station, before leaving the vicinity of the station. The later
undocking will have no impact to Atlantis' landing at Kennedy Space
Center which still is planned for 1:18 a.m. CDT Monday, May 29th.
Later this evening
at 10:11 p.m. CDT, Halsell, Horowitz and Helms will participate in a
trio of interviews with the ABC Radio Network, KOIN-TV in Portland,
Oregon, and a webcast education event for the Housing and Urban Development
agency.
The Atlantis and
station complex continues to operate well, completing one orbit of the
Earth every 91 minutes.
The next status
report will be issued at 6 a.m. on Thursday.
