A new cargo freighter launched from the Baikonur Cosmodrome in
Kazakhstan to the International Space Station at 10:25 p.m. CDT Friday
with more than 2.5 tons of fuel, air, water and other supplies and
The ISS Progress 25 unpiloted cargo carrier is scheduled to dock with
the station Tuesday at 12:10 a.m., bringing more than 1,050 pounds of
propellant, almost 100 pounds of air, more than 925 pounds of water and
3,042 pounds of dry cargo -- a total of 5,125 pounds. NASA TV coverage
of the docking will begin at 11:30 p.m. Monday
The spacecraft will use the automated Kurs system to dock at the aft
port of the Zvezda Service Module. Should human intervention be
necessary, Expedition 15 Commander Fyodor Yurchikhin will be at the
manual TORU docking system controls.
On Tuesday, Yurchikhin and flight engineers Suni Williams and Oleg Kotov
tested communications between the station and the docked ISS Progress
24. On Wednesday, in recognition of the Russian holiday Victory Day,
marking the end of World War II, the crew performed only necessary
On Thursday, Kotov worked with a breathing experiment, while Williams
and Yurchikhin spent about three hours replacing a frayed steel rope on
a gyroscope on the Treadmill Vibration Isolation System, or TVIS. The
gyroscope is part of the system that keeps vibrations created by an
exercising crew member from being transmitted to the rest of the
station, where it could interfere with delicate experiments. Williams
and Yurchikhin wrapped up the work on Friday.
Additionally on Thursday, flight controllers tested the failed Control
Moment Gyroscope (CMG) 3. The test involved tilting the CMG in different
directions at different speeds to determine what effect, if any,
friction had on the movement. The 600-pound gyroscope itself, one of
four that controls the station’s orientation in space, was not spun up.
It will be replaced this summer during the STS-118 mission.

The next station status report will be issued Tuesday, May 15, after the
Progress 25 docking, or earlier if events warrant.
