forecast for the Shuttle Landing Facility for Thursday morning, permitted Atlantis to be cleared for a landing the next day. The crew spent the remainder of the day in preparation for landing, packing up gear and stowing the Ku band antenna used for TV broadcasts. During the inspection, the crew was notified that the Soyuz TMA-9 spacecraft was docked with the ISS above, which carried the first half of the Expedition 14 crew. September 21 (Flight day 13 and landing) Flight day 13 was the last day of the mission, with the final re-entry procedures and landing taking place during the morning, and numerous debriefs and conferences in the afternoon. The landing process began hours before the actual landing at Kennedy Space Center. The process began with the APU prestart at 04:37 EDT, followed by the closing of the payload bay doors and sealing of the Orbiter at 04:45 EDT. Atlantis crew received the final "Go" for the prime re-entry window from Mission Control in Houston at 04:52 EDT. The crew then started the deorbit reorientation of the shuttle so that its engines faced in its direction of travel, meaning that by firing the engines for the deorbit burn Atlantis would slow down and begin its descent out of orbit. The de-orbit burn was initiated at 05:15 EDT, lasting 2 minutes 40 seconds with two engines burning well throughout. The astronauts aboard the Orbiter were informed at 05:17 EDT that their burn was perfect, with no alterations required as Atlantis began her drop through the atmosphere above the Indian Ocean. Following the deorbit burn, the crew of Atlantis began dumping excess propellant overboard, a process lasting 3 minutes, concluding at 05:26 EDT, with the Orbiter 55 minutes away from landing. Twenty-five minutes later, at 05:51 EDT, Atlantis began feeling the effects of the atmosphere at an altitude of approximately , and soon after began its "roll reversal banking" in order to bleed off most of the she was traveling at, ready for landing at less than . The ISS was positioned in such a way as to be above the reentry path taken by Atlantis, so the astronauts were able to observe the entire maneuver from above. At 06:08 EDT, the downlink from the Shuttle was acquired by the MILA tracking station on Merritt Island, Florida, with GPS data beginning to be accepted by the Orbiter three minutes later. Ten
