The deorbit burn phase began successfully at 7:07 am CDT, committing "Discovery" to land on the 17th. At 8:08 am CDT, "Discovery" was safely out of reentry and headed toward a landing at KSC runway 15. The original landing target (Runway 33) was ruled out at the last minute due to showers south of KSC where the orbiter would have circled before landing. Shortly before landing the right air data probe initially failed to deploy. It began functioning of its own accord a few minutes later.
