If you keep up with NASA and the space program you know that the Shuttle Discovery is on her last mission. That mission is designated STS-133 and she has been working at the International Space Station (ISS) for the last week or so.
This theme is intended to commemorate this final mission of Discovery and her crew and it features shots of her, the astronauts and the ISS while they were performing docked operations.
There is nothing like seeing these magnificent men, women and machines in space to fire up your imagination and wonder!
