Johnson Space Center, Houston (AP) It's arrival day for the Space Shuttle Endeavour's astronauts as they prepare to dock with the international space station.
Tonight's arrival, after a sleep period, marks the start of a grueling schedule that includes five spacewalks to perform station construction work.
Specialists on the ground are going over launch images of a possible impact to Endeavour's nose.
A new photographic flash system captured a possible strike to Endeavour's nose 10 seconds after liftoff. In addition, a piece of foam or other debris came off Endeavour's tank just over a minute into the flight. It appeared to miss the right wing.
The shuttle crew also spent time yesterday examining the exterior of the spacecraft.
