In Firing Room-4 in the Launch Control Center at NASA's Kennedy Space Center in Florida, launch controllers took their posts at about 2:30 p.m. EST for space shuttle Discovery's STS-133 mission to the International Space Station. The countdown clock began ticking backward from the T-43 hour mark at 3 p.m.
Scheduled to lift off Feb. 24 at 4:50 p.m. EST, Discovery and its six-member crew will deliver the Permanent Multipurpose Module, packed with supplies and critical spare parts, as well as Robonaut 2, the dexterous humanoid astronaut helper, to the orbiting outpost.
