NASA – Discovery will deliver and install the Permanent Multipurpose Module, the Express Logistics Carrier 4 and provide critical spare components to the International Space Station. This will be the 35th shuttle mission to the station.
It’s been the first shuttle to venture into new territory several times, and it’s about to do so again: Following the STS-133 mission, Discovery will be the first of the shuttle fleet to retire.
“We’re wrapping up the Space Shuttle Program,” said STS-133 Commander Steve Lindsey. “Besides the excitement of completing the International Space Station and all the things we do, I hope people get a sense of the history of what the shuttle is and what we’ve done and what’s ending. Because they’ll probably never see anything like it flying again.” more> http://tinyurl.com/23l5ujd
