(AP) -- Space shuttle Endeavour's astronauts are inspecting their ship to make sure it's safe for Friday's landing.
The survey of the wings and nose, being conducted Wednesday morning, is standard before a shuttle returns to Earth. NASA wants to make sure Endeavour's heat shield was not pierced by micrometeorites or space junk during its two weeks in orbit. The astronauts used a laser-tipped boom to check for damage.
Endeavour and its crew of seven left the international space station Tuesday.
As the inspection was under way, an unmanned Russian vessel carrying several-thousand pounds of supplies docked at the station. Commander Gennady Padalka had to manually guide the craft in because of a problem with its automatic system.
