Atlantis’ crew woke at 12:20 a.m. EDT to "Supermassive Black Hole" by Muse, played for Commander Ken Ham.
At 3:40 a.m., the astronauts will begin deorbit preparations for landing, and Atlantis’ payload bay doors are scheduled to be closed at 5:01 a.m.
Mission Control Entry Flight Director Toni Ceccacci and his team are overseeing Atlantis’ systems and monitoring weather conditions at Kennedy Space Center’s Shuttle Landing Facility. Astronaut Lee Archambault will fly weather reconnaissance and report the results to Mission Control. Ceccacci and his team are expected to make a “go/no go” decision for the deorbit burn at 7:21 a.m. The burn would occur at 7:41 a.m. followed by a landing at Kennedy’s runway 33 at 8:48 a.m.
