The tenth crew of the
International Space Station (ISS) made a short spaceflight early Monday to move a Russian lifeboat
to a new docking port and prepare the station for a pair of upcoming spacewalks.
Tucked inside
their Russian-built Soyuz TMA-5
spacecraft, pilot Salizhan Sharipov and his ISS Expedition 10 crewmate
Leroy Chiao deftly moved the spacecraft from the station's Pirs docking
compartment to a new berth at the Zarya control module, its final resting place
for the remainder of the crew's six-month mission.
Sharipov
undocked the Soyuz lifeboat from Pirs at about 4:29 a.m. EST (0929 GMT) and minutes later backed away to
a safe distance of about 98 feet (30 meters). He then flew the vehicle
45 feet (14 meters) over to the Zarya docking port and redocked at about 4:53 a.m. EST (0953 GMT).
The entire spaceflight took just 20 minutes. Chiao
and Sharipov doffed their Russian-built Sokol spacesuits after docking
and were expected to reenter the ISS at about 6:55 a.m. EST (1155 GMT) and
return the station to normal operations.
While brief,
the Soyuz redocking maneuver was essential for Chiao and Sharipov in order to clear the
Pirs compartment for use during two spacewalks tentatively set for January and March of
2005. During those spacewalks, Chiao and Sharipov will install science
and engineering equipment to the ISS exterior and prepare the station to receive a
new European cargo expected to launch in the fall.
Monday's spaceflight marked the first time the
Expedition 10 crew left the ISS unmanned since they arrived at the station on
Oct. 16. The two astronauts will also leave the station devoid of humans during
both of their upcoming spacewalks.
Initially slated to be used as an emergency lifeboat
for ISS crews, Russia's Soyuz spacecraft are currently the only vehicles
available for station crew exchange. NASA's space shuttle fleet has been
grounded since the loss of Columbia and its crew on Feb. 1, 2003. The next
shuttle flight to the ISS is slated to launch sometime between May and June of
2005.
Expedition 10's Soyuz relocation flight was the first
port-to-port maneuver since ISS Expedition 4 crew Yury Onufrienko, Daniel Bursch
and Carl Walz repositioned their Soyuz spacecraft on April 20, 2002.
