Space Shuttle Endeavor's last flight is scheduled for Friday, April 29th, at 2:47 PM CST. You may be able to watch the launch on NASA TV, where they will also broadcast videos throughout Endeavor's mission at the International Space Station. Friday's launch coverage begins at 9:30 AM. NASA has also created a playlist for STS-134 on their YouTube channel.
The mission commander for STS-134 is Captain Mark Kelly, the husband of Congresswoman Gabrielle Giffords. Congresswoman Giffords was recently cleared by her physicians to attend the shuttle's launch in Florida. This is the thirtieth and last year of NASA's Space Shuttle program, as well as the fiftieth year of manned space flight. The last flight of Atlantis is scheduled for launch from Kennedy Space Center on June 28th. The Smithsonian's Air and Space Museum has a number of exhibits and features on the shuttle program that you can explore on their website.
