The action shifted
back inside the International Space Station on Thursday, as Discovery
astronauts completed connections for the newly installed Z1 external
framework structure and transferred equipment and supplies for the first
resident crew of the Station, the Expedition One crew, scheduled to
arrive early next month.

The crew also tested
the four 630-pound gyroscopes in the truss, called Control Moment Gyros,
which will be used to orient the ISS as it orbits the Earth. The crew
spun up the gyros to about 100 revolutions per minute, largely to confirm
their speed and power consumption. They will ultimately be spun up to
about 6,000 revolutions per minute once they assume attitude control
of the ISS following the arrival of the U.S. Laboratory Destiny, scheduled
for January.

Mission Specialists
Bill McArthur and Leroy Chiao used a laptop computer to conduct the
tests, which included turning on the gyroscope heaters. The heaters
are designed to keep the gyros from being damaged by the cold of space.

Those tests, and
the transfer of supplies into the Russian Zarya Module took longer than
expected. As a result, the crew’s final departure from the Station’s
Unity module was delayed until Friday morning, which, in turn, will
delay Discovery’s undocking from the ISS for about ninety minutes to
10:09 a.m. CDT time Friday. The later undocking time will have no impact
on other Shuttle operations for tomorrow.

Pilot Pam Melroy
and Mission Specialist Jeff Wisoff took samples from surfaces in Zarya
to study the module’s environment. Melroy and Wisoff also unclogged
a solid waste disposal system in the Shuttle’s toilet, which was restored
to full operation after a brief interruption in service.

In other news,
NASA and Russian officials announced today that the Expedition One crew
will be launched on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan
on Tuesday, Oct. 31 at 1:53 a.m. central time, 10:53 a.m. Moscow time.
The one day adjustment in the launch date was made to accommodate the
Soyuz rendezvous requirements needed to reach the ISS two days after
liftoff. Docking of the Soyuz and the Expedition One crew, Commander
Bill Shepherd, Soyuz Commander Yuri Gidzenko and Flight Engineer Sergei
Krikalev is now set for Thursday, Nov. 2, at 3:20 a.m. central time,
12:20 p.m. Moscow time.

Discovery’s astronauts
will begin an eight-hour sleep period at 9:17 p.m. CDT tonight and will
be awakened at 5:17 a.m. Friday to prepare for their undocking.

Discovery continues
to orbit the Earth in good shape with landing scheduled for Sunday afternoon
at the Kennedy Space Center.

The next Mission
Control Center status report will be issued about 7 a.m. Friday, or
as events warrant.

Note to Editors:
The JSC newsroom will be closed from 9:30 p.m. this evening until 5
a.m. Friday.
