A couple of weeks ago, Odyssey slipped from its path during a common orbit-adjustment maneuver, and put itself into safe mode. Mission managers said July 16 they weren't sure whether Odyssey would be overhead when the Mars Science Laboratory spacecraft deposits the Mars rover Curiosity at Gale Crater Aug. 5. They later determined that Odyssey would have flown overhead two minutes after landing. This wouldn't have affected the rover's autonomous landing at all, just NASA's ability to find out what happened as quickly as possible.
