The first EVA of STS-133 was completed on Flight Day 5 by astronauts Steve Bowen and Al Drew. The two astronauts installed equipment on numerous positions outside the International Space Station, including a power extension cable between the Unity and Tranquility nodes to provide a contingency power source. NASA selected Bowen to replace mission specialist Tim Kopra, who was injured in a bicycle accident. Bowen will perform two spacewalks on this mission. He is the first U.S. astronaut to fly on back-to-back missions and was a mission specialist on STS-132, which flew in May 2010.

Space shuttle Discovery was successfully launched from Kennedy Space Center in Florida at 4:53 p.m. EST Thursday, February 24, 2011 from NASA's Kennedy Space Center in Florida, with Commander Steve Lindsey leading the STS-133 crew to deliver the Permanent Multipurpose Module and Robonaut 2 to the space station.

This mission marks the final flight of the Space Shuttle Discovery. Having been the most active space shuttle in the fleet, Discovery now flys the entire space shuttle fleet into retirement. Space Shuttle Discovery has the distinction of being the only space shuttle to serve in both return to flight programs, once after Space Shuttle Challenger STS-51L exploded on January 28, 1986 and again after the tragic break up of Space Shuttle Columbia STS-107 during re-entry.
