CAPE CANAVERAL, Fla. -- On twin pillars of fire, space shuttle Discovery lifts off Launch Pad 39A at NASA's Kennedy Space Center in Florida beginning its final flight, the STS-133 mission. Launch to the International Space Station was at 4:53 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. Discovery is flying on its 39th mission and is scheduled to be retired following STS-133. This is the 133rd Space Shuttle Program mission and the 35th shuttle voyage to the space station.
