Astronauts bring supplies to
Space Station
'Pakistan Times' Monitoring Desk
CAPE CANAVERAL, Fla. (US):
It was moving d ay
Friday for the crew of Discovery, which transferred thousands of pounds of
supplies and cargo from the space shuttle to the international space
station.
The astronauts moved a huge cargo container, nicknamed Leonardo, onto the
space station by robotic arm. Among the goodies awaiting the space station
crew were a new stationary bicycle for exercise, an oxygen generator that
will eventually allow the space station to support six inhabitants, a
machine that cools the station's cabin air and a lab freezer for scientific
samples.
"Have fun putting a new room on the station today — the float-in closet,
every home needs one," flight controllers in Houston wrote the shuttle crew
in their daily morning electronic message.
Unloading items 220 miles above Earth was even more difficult than moving
into a house since at least there's gravity on the ground, Steve Lindsey,
Discovery's commander, said in interviews with reporters on the ground.
"It's really kind of a challenge because you're in zero-G ... you've got to
go very, very slow because if you go fast, you kind of run into things and
bump into other equipment," Lindsey said. "It's kind of an interesting
choreography we have to go through."
For the first time in three years, the international space station has three
crew members — European Space Agency astronaut Thomas Reiter on Thursday
joined Pavel Vingogradov and Jeff Williams, who marked their 100th day at
the space station Friday.
Discovery's six remaining shuttle crew members awoke Friday to a recording
of The Beatles' "Good Day Sunshine," a choice of astronaut Lisa Nowak's
family.
Nowak and astronaut Stephanie Wilson planned to use the shuttle's robotic
arm and an extended boom to take close-up pictures of areas on the orbiter's
underside that engineers need more information about to reassure themselves
that there's no damage like the kind that doomed Columbia's flight in 2003.
"We've got a couple of really minor problems," pilot Mark Kelly told
reporters Friday. "You know they're not significant enough to be called
nuisances."
The boom will look at the shuttle's nose cap area, which eluded earlier
photography and may have some bird droppings on it, and three places where
gap filler is sticking out, including one protrusion as long as an inch.
Gap filler is material fitted between thermal tiles to prevent them from
rubbing against each other. Two pieces of gap filler had to be removed from
Discovery's belly during a spacewalk last year because of concerns they
would cause problems during re-entry.
Engineers also want to look at a panel on the right wing where there appears
to be a dark spot in the shape of a claw and another panel where there are
two black scuff marks.
The robotic arm and boom were used two days ago to examine the shuttle's
nose cap and wings for damage. Before docking Thursday, Lindsey maneuvered
the shuttle into a back flip so that the space station's crew could
photograph the shuttle's belly and transmit to the images to engineers in
Houston.
In their morning message, the flight controllers told the shuttle crew that
the shuttle, while docked to the station, wouldn't be able to use a thruster
whose heater malfunctioned since its temperature likely was to drop to 60
degrees, about 30 degrees below the use limit.
Flight controllers also told Discovery's crew that they expected NASA
managers on Friday to extend the mission by a day to allow for a third
spacewalk. That would bring the mission to 13 days.
Columbia's seven astronauts were killed during re-entry when fiery gases
entered a breach in the shuttle's wing. The breach was caused by foam
hitting its external tank.●
