At NASA's Kennedy Space Center in Florida, Associate Administrator for Space Operations Bill Gerstenmaier, left, Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach talk to media following a Flight Readiness Review that gave a unanimous "go" to launch space shuttle Discovery on the STS-133 mission to the International Space Station. This will be the second launch attempt for Discovery, following a scrub in November 2010 due to a hydrogen gas leak at the ground umbilical carrier plate (GUCP) as well as modifications to the external fuel tank's intertank support beams, called stringers.
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.
