After
linking up with the international
space station, Endeavour's astronauts got right to work Thursday
unloading the parts they'll need to build a giant robot that will help maintain
the orbiting outpost. Astronauts Robert Behnken and Gregory Johnson were using
the station's robotic arm to pull a pallet containing the Canadian robot, named
Dextre, from Endeavour's cargo bay and install it temporarily on a station
girder. Dextre — short for dexterous and pronounced like Dexter — is designed
to assist spacewalking astronauts and, ultimately, to take over some of their
dangerous outdoor work.
Spacewalkers Richard Linnehan and Garrett Reisman will begin assembling the robot late Thursday night during the first of five outings planned for Endeavour's busy 16-day mission. Before pulling up to the space station, Endeavour's commander, Dominic Gorie, guided the shuttle through a 360-degree backflip to allow for full photographic surveillance. It's one of the many safety-related procedures put in place following the Columbia tragedy in 2003.
The space station crew used cameras with high-powered zoom lenses to photograph Endeavour from nose to tail, especially all the thermal tiles on its belly. The pictures — as many as 300 — will be scrutinized by engineers on the ground to see whether the shuttle suffered any damage during Tuesday's launch and ascent. The crew had already used a 100-foot laser-tipped boom to inspect Endeavour's wings and nose, and flight director Mike Moses said engineers haven't spotted any problems.
