edpaffjr.comSpace shuttle Discovery launched about an hour ago on its final mission before retirement. The shuttle is now on its way to the International Space Station and once complete there will only be two more shuttle missions before the entire fleet is retired. In addition to the six member crew, this shuttle is carrying the first humanoid robot in space, Robonaut2, along with various pieces for the Space Station. It is always cool to watch these launches, and now only two remain, scheduled for April 19 and June 28.
