After getting an 8 p.m. EDT wake-up call inside the Astronaut Crew Quarters at NASA’s Kennedy Space Center in Florida, the seven Discovery astronauts are climbing into their bulky, orange launch-and-entry suits. Once suited, they’ll depart for Launch Pad 39A, where Discovery is poised for flight.
The countdown clock is currently still in a planned hold at T-3 hours, which will end at 2:26 a.m. Liftoff is set for 6:21 a.m.
