English: CAPE CANAVERAL, Fla. – At the Operations and Checkout Building at NASA's Kennedy Space Center in Florida, space shuttle Discovery's STS-133 astronauts, dressed in their orange launch-and-entry suits, pause for a group portrait in front of the Astrovan which will transport them to Launch Pad 39A. From left are Mission Specialists Nicole Stott, Michael Barratt, Alvin Drew and Steve Bowen; Pilot Eric Boe; and Commander Steve Lindsey. 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 International Space Station. Discovery, which will fly its 39th mission, is scheduled to be retired following STS-133. This will be the 133rd Space Shuttle Program mission and the 35th shuttle voyage to the space station.
