The most recent forecast looks promising, with scattered clouds at 3,000 and 20,000 feet, but no violations of landing rules.
The crew woke at 3:23 a.m. EST today - to the tune, "Coming Home" by Gwyneth Paltrow - to begin preparations to drop Discovery from orbit for the last time, on the mission's 13th day and 202nd orbit.
A key early milestone occurs around 8 a.m. with approval to close the orbiter's payload bay doors, a signal that flight directors are pressing forward with the first landing attempt.
If all goes well, Discovery will fire its orbital engines in the direction of travel at 10:47 a.m. to brake its speed, initiating a fiery re-entry through the atmosphere and roughly hour-long plunge back to Earth.
If weather takes a turn for the worse, a second landing attempt is available one orbit later at 1:34 p.m.
We'll have live coverage of the Discovery's final landing starting around 8 a.m. Here's a look at some of the highlights of the day's schedule:
-- 6:53 a.m.: Deorbit preparations begin.
-- 8:12 a.m.: Payload bay doors closed.
-- 9:29 a.m.: Crew begins to don launch-and-entry suits.
-- 9:52 a.m.: Crew straps into seats.-- 10:42 a.m.: “Go-No go” decision for deorbit burn.
-- 10:47 a.m.: Discovery maneuvers into position for deorbit burn.
-- 10:52 a.m.: Deorbit burn.
