cast off a spent cargo ship from the International Space Station (ISS) early
Friday in move that will free up a docking port outside the orbital laboratory.
12 commander Bill McArthur and flight engineer Valery Tokarev undocked the
19 vehicle, an unmanned supply ship that sat at the aft end of the station’s
Zvezda service module since its Sept. 10 arrival.
and Tokarev crammed Progress 19 with trash, unneeded equipment and clothes and
siphoned its last remaining supplies of water and oxygen before undocking it at
5:06:10 EST (1006:10 GMT) Friday. After a brief engine firing to fly clear of
the space station, the Progress 19 vehicle began its Earthward descent and is
expected to burn up in the planet’s atmosphere.
parts of the spacecraft may survive atmospheric reentry and plummet into the
Pacific Ocean about 1,864 miles (3,000 kilometers) east of Wellington, New
Zealand, Russian ISS mission control spokesperson Valery Lyndin told the Interfax
departure clears the way for a brief spaceflight on March 20 by the Expedition
12 astronauts. McArthur and Tokarev are expected to relocate
their Soyuz TMA-7 vehicle from its berth at the Earth-facing port on the
station’s Zarya control module in anticipation of their relief crew’s arrival.
In a daily
ISS update, NASA spokesperson Rob Navias said the “Progress and Soyuz shell game”
clears the Zarya docking port for Expedition
13 commander Pavel Vinogradov, flight engineer Jeffrey Williams and Marcos
Pontes – Brazil’s first astronaut. Pontes and the Expedition 13 crew will
launch from Baikonur Cosmodrome in Kazakhstan on March 29 at 9:30 p.m. EST (0230
March 30 GMT) and dock the station two days later.
their short spaceflight, McArthur and Tokarev will each don their Russian-built
Sokol spacesuits, climb inside their Soyuz vehicle and undock from the ISS at 1:45
a.m. EST (0645 GMT). By 2:22 a.m. EST (0722 GMT), they should arrive at the
station’s Zvezda berth, NASA officials said.
and Tokarev are less than six weeks away from completing their six-month
mission aboard the ISS. The two astronauts arrived aboard the station in
October 2005 and are expected to return to Earth with Pontes in early April.
Progress 19 has left the ISS, another unmanned cargo ship remains parked at the
station’s Pirs docking compartment. That resupply ship, Progress
20, arrived at the ISS on Dec. 23.
