With Houston's Mission Control Center (MCC) back in operation, the
deliberate power up of the International Space Station is proceeding as
planned.  The huge U.S. solar wings are again tracking the sun after
being put in a fixed position when the Mission Control Center here was
powered down in the face of a threat from Hurricane Lili.

Houston flight control of the station was resumed about 6 p.m. Thursday.
That was a little over 12 hours after reactivation of MCC Houston, begun
when it became apparent that Lili would not hit the area.

Members of the Houston Support Group in Mission Control Moscow had taken
over control of the station's U.S. segment early Wednesday, when Lili was
churning in the Gulf of Mexico and its landfall uncertain.  The group
followed a contingency plan setting up a Backup Control Center (BCC) in
MCC Moscow. They communicated with the station using Russian and U.S.
ground stations, and remained in close telephone contact with flight
control teams gathered in a conference room at Johnson Space Center.

While the BCC was in operation, high-rate data downlink from the station
was not available.  Since they were unable to monitor the movement of the
solar arrays, flight controllers put them in a fixed position.  As a
result, power to some station payloads and systems was reduced. The
repowering process is being carried out largely by flight controllers.

Russian and Houston-based station officials praised the smoothness of the
handovers to the BCC and back to Mission Control Houston, as well as the
performance of the BCC itself. The Houston Support Group, U.S. flight
controllers and others based in Mission Control Moscow, and Mission
Control Houston practiced for just such a contingency less than three
weeks ago. 

As Lili approached on Wednesday, power at MCC Houston was turned off in a
carefully planned sequence, and its electronic equipment covered with
waterproof plastic sheets.  Today, operations are essentially back to

The hurricane precautions in Houston led to a delay in the launch of
Atlantis on the STS-112 flight to the space station.  Atlantis, bringing
the Starboard 1 Truss segment to the station, is now scheduled to launch
on Monday. Preparations for the launch are going smoothly. 

The situation also caused the Russians to cancel a scheduled Wednesday
test of thrusters on Progress 9, the unpiloted cargo vehicle that docked
to the rear of the station's Zvezda Service Module on Sunday. They also
canceled a station reboost by the Progress, which had been scheduled for

The Expedition 5 crew, Commander Valery Korzun, NASA International Space
Station Science Officer Peggy Whitson, and Cosmonaut Sergei Treschev, had
a relatively quiet Friday to wind up their hurricane-impacted workweek
about 240 statute miles above the Earth's surface. Science activities and
station maintenance continued.  The crew also devoted some time to
unloading the Progress 9 unpiloted supply spacecraft docked at the back
of the station's Zvezda Service Module.
Information on the crew's activities aboard the space station, future
launch dates, as well as station sighting opportunities from anywhere on
the Earth, is available on the Internet at:

Details on station science operations can be found on an Internet site
administered by the Payload Operations Center at NASA's Marshall Space
Flight Center in Huntsville, Ala., at:

The next ISS status report will be issued as part of an STS-112 status
report once Atlantis launches, or sooner if developments warrant.
