Astronauts check for damage

Houston - The space shuttle Discovery's crew found no damage on Wednesday after inspecting the orbiter's nose and wings for damage with a special robotic arm, a top Nasa official said.
"We have a very clean vehicle," shuttle flight director Tony Ceccacci said of the initial safety check, which came on the first full day of orbit.
The two-woman, five-men crew was checking for possible damage from loose foam that came off the craft a couple of minutes into Tuesday's critical launch, only the second since the February 2003 Columbia disaster.
Nasa said the team was "working very hard" to complete the safety check in 24 hours and that initial indications were all good.
"It will take about eight to 10 hours to get a very good look at the first part of the survey and we should have ... that completed within 24 hours," Ceccacci said. "Everything seems to be clear."
Discovery's crew members - Commander Steven Lindsey, pilot Mark Kelly and mission specialists Michael Fossum, Lisa Nowak, Stephanie Wilson, Piers Sellers and European Space Agency astronaut Thomas Reiter of Germany - deployed a robotic arm equipped with cameras and a laser to check on the shuttle.
The crew focused on the protective heat shield on the shuttle wings' leading edge.
The astronauts will then configure their spacesuits in preparation for two or three spacewalks after the shuttle docks with the International Space Station (ISS) on Thursday.
Struggled to fix problems
Reiter will join the ISS's two other crew members, Commander Pavel Vinogradov of Russia and Flight Engineer Jeffrey Williams, for a long-term stay and will undertake two spacewalks.
Tuesday's launch marked just the second shuttle mission since Columbia splintered apart upon re-entry into Earth's atmosphere, leading to the grounding of shuttle flights for nearly two and a half years.
But Nasa appeared pleased with the performance of Discovery's external fuel tank, which lost only small pieces of foam insulation on Tuesday.
Nasa officials have struggled to fix problems associated with the persistent loss of foam insulation since the debris doomed Columbia.
Foam fell off Columbia's fuel tank 70 seconds after lift-off, piercing its heat shield.
Foam also peeled off Discovery's tank in the first post-tragedy launch last year, but the debris missed the shuttle.
Nasa placed more than 100 cameras around Discovery's launch pad for Tuesday's lift-off to detect any loose debris. The ISS will then take pictures of the vessel's heat shield while it performs a back flip during its approach.
The agency had said the seven astronauts could take refuge at the ISS and wait for a rescue mission in the event the shuttle suffered irreparable damage.
