HOUSTON - Space
shuttle Endeavour touched down in Florida on Friday morning, bringing to an end
a successful 16-day mission to complete Japan's Kibo science laboratory at the
International Space Station (ISS).
Shuttle
commander Mark Polansky piloted Endeavour to a 10:48 a.m. EDT (1448 GMT)
landing at NASA's Kennedy Space Center, beating the weather - which
called for a chance of rain - for a smooth landing at its home port in Cape
Canaveral, Fla. The astronauts landed after delivering a brand new experiment
porch to the space station along with vital spare parts and a new crewmember
for the outpost's six-man crew.
"Welcome home!"
NASA astronaut Alan Poindexter radioed Endeavour's crew from Mission Control in
Houston. "Congratulations on a superb mission from beginning to end. Very
well done."
"That's
what it is all about," Polansky replied after thanking the whole flight team.
"We're happy to be home."
Returning home
with Polansky and Hurley were STS-127 mission specialists Dave Wolf, Tom
Marshburn, Chris Cassidy and Canadian Space Agency astronaut Julie Payette.
Cassidy became the 500th person in space during the 6.5 million-mile (10.4
million-km) mission.
Their seventh
crewmate for the trip home was Japan's first long-duration space station
resident, Koichi Wakata. A flight engineer for three successful station crews
since March, Wakata spent 138 days in space before being replaced by NASA
astronaut Tim Kopra, who launched on Endeavour and will return to Earth with
the next shuttle mission targeted for launch in late August.
"I long for
sushi, so that's the first thing I would like to have," said Wakata, who
returned to Earth just one day before his 46th birthday. He added that a dip in
one of Japan's hot springs is also high on his list.
A NASA
spokesperson confirmed that Wakata did indeed have sushi waiting for him after
disembarking the shuttle Endeavour. He also brought home some high-tech
underwear and other clothing designed to be stink-free and antistatic,
which wore for a month at a time to test the Japanese-made space garb. Wakata
said he received no complaints from his crewmates.
Front porch
installed, batteries replaced
Endeavour
rocketed to orbit July 15 and reached the space station two days later to begin
its ambitious construction flight. The combined seven-member shuttle crew and
six-man station staff formed the largest crowd aboard any one spacecraft in
history - 13 people.
"We
certainly miss being there, but there's no place like home," Polansky said.
One of the
station's two
space toilets and a carbon dioxide removal device broke down during the
mission. Both were swiftly repaired, but the carbon dioxide scrubber shut down
again Wednesday. Station astronauts hoped to repair it soon.
Pilot
Hurley said the best moments of the flight came during those rare moments of
downtime, when all 13 astronauts could gather together, swap stories and tell
jokes.
"It just
seemed a little funnier up here," Hurley said before landing.
Endeavour's
primary mission was to deliver the final component of the Japan Aerospace
Exploration Agency's $1 billion Kibo ("Hope") laboratory, an
exterior platform designed to support experiments. Its installation,
including the addition of three initial payloads, required a combination of
five spacewalks and the use of three robotic arms, including the Japanese arm
on Kibo.
Wolf led
Endeavour's spacewalking team to install the Kibo porch, deliver vital spare
parts and replace aging solar array batteries during the shuttle flight. They also added vital cameras to Kibo in preparation for the arrival of Japan's first unmanned cargo ship in September.
The space
station is now 83 percent complete and weighs 685,000 pounds, with seven more
shuttle flights ahead to finish construction by 2010, when NASA plans to retire
its three-shuttle fleet. It has a wingspan as long as an American football
field and can be easily seen at night by the unaided eye.
"I can't
say enough how great this mission was," NASA's space operations chief Bill
Gerstenmaier said after Endeavour landed. "The crew and the ground teams pulled
it all together."
One of the best
Despite an early
concern for tile damage as a result of foam debris falling off of Endeavour's
external fuel tank during launch, mission managers praised STS-127 for its
relative clean performance over the course of its 248 orbits.
"It's been as
good as some of the best ones we've flown in the last year or two," said
mission management team chair Leroy Cain. "Certainly one of the best."
In addition to
the foam strikes, which were cleared for re-entry after a series of routine
heat shield inspections, Endeavour experienced an issue with one of its three
power-providing fuel cells and lost use of one of its forward thrusters. Both
problems however, posed no impact to the STS-127 mission.
Now back on
Earth, Endeavour will be serviced and prepared for its next flight, STS-130,
scheduled for a return trip to the International Space Station early next year.
NASA's next shuttle mission, STS-128, is targeted for launch on Aug. 25 aboard
orbiter Discovery pending a check of its fuel tank foam insulation.
