Bowen on middeck

S133-E-006028 (25 Feb. 2011) --- Near space shuttle Discovery's airlock, astronaut Steve Bowen, STS-133 mission specialist, hovers momentarily on the middeck. Perhaps he is thinking about next week's extravehicular activity (EVA) on the International Space Station to which he has been assigned as a replacement for an original prime crew member who was injured in an accident weeks prior to the shuttle's scheduled launch.
