Mission Control has confirmed space shuttle Discovery's successful deorbit burn. The burn lasted from three to four minutes, slowing Discovery enough to begin its descent.

Touchdown on runway 15 at Kennedy's Shuttle Landing Facility will be at 3:14 p.m. EDT. Meanwhile, the landing crews are ramping up into high-gear for Discovery's arrival.

Live landing coverage is available on NASA TV and NASA's Launch Blog.

There will be a post-landing news conference at no earlier than 2 hours after landing and a crew post-landing news conference, at no earlier than 5 1/2 hours after landing. Both events will be broadcast on NASA TV.
