Two
astronauts working aboard the International Space Station (ISS) took a short
trip early Friday during a relocation flight aboard their Russian-built Soyuz
spacecraft.
Clad in
their Sokol spacesuits, ISS Expedition
12 commander Bill McArthur and flight engineer Valery Tokarev successfully moved
their Soyuz TMA-7 spacecraft to a new docking port to free up a Russian-built
airlock for an upcoming spacewalk.
Tokarev
commanded the 19-minute Soyuz flight, which began at the Pirs docking
compartment at 3:46 a.m. EST (0846 GMT) while the ISS flew 220 miles (354
kilometers) over the South Atlantic Ocean off the coast of South America.
"Okay, we're
moving along," Tokarev said as the Soyuz pulled away from the ISS.
The two
astronauts moved the Soyuz spacecraft about 45 feet (13 meters) during the
flight and docked the spacecraft at a berth outside the Russian-built Zarya
control module at 4:05 a.m. EST (0905 GMT) while passing over Northern Africa's
Sahara Desert.
"Everything
looks great," Tokarev said.
Both the
ISS and Soyuz vehicles flew about 5,500 miles (8,851 kilometers) across Earth
during the short flight.
The Soyuz
relocation clears the Pirs docking compartment for the Expedition 12 crew's second
spacewalk, during which McArthur and Tokarev will don Russian Orlan spacesuits
to work outside the ISS.
Originally
set for Dec. 7, the spacewalk will likely be rescheduled to late January or
early February to ease a rather packed month of work for McArthur and Tokarev
in December, NASA officials said. The two astronauts are set to discard the
unmanned cargo ship Progress
19 from its berth at the aft end of the station's Zvezda service module on
Dec. 20 to make way for its replacement - Progress 20 - set to dock there on
Dec. 23, they added.
Russia's
Federal Space Agency, which Tokarev represents aboard the ISS, will launch the
Progress 20 supply ship from Baikonur Cosmodrome in Kazakhstan on Dec. 21, NASA
officials said.
During
today's spaceflight, McArthur and Tokarev left the ISS in an unmanned
configuration, with many systems controlled from the ground, as a precautionary
measure in case their spacecraft was unable to redock properly.
Their Soyuz
TMA-7 spacecraft will remain at its Zarya port for the remainder of the astronauts'
six-month mission. McArthur and Tokarev arrived
at the ISS aboard the spacecraft with U.S. space tourist Gregory
Olsen on Oct. 3, 2005.
