Sensors on the shuttle Atlantis have recorded hits on the leading edges of the wings, around the area where Columbia suffered fatal damage four years ago, NASA officials said Tuesday. However, they emphasised that the hits probably did no damage to Atlantis.
The officials said the areas would be inspected to make certain that the wing will be safe.
The hits could have been caused by a collision with a small meteorite or a piece of space junk  in orbit, according to an internal NASA memo. However, it was more likely that the detections were caused by "thermal settling" or deformation rather than an actual impact.

Astronauts will try to fix a thermal blanket that peeled back during Atlantis' launch, extending the space shuttle's mission from 11 to 13 days.
No decision had been made on whether the loosened blanket, covering a 4-by-6-inch area over a pod for engines, will be repaired during a previously planned third spacewalk or a fourth, extra one.
