If witnessing a shuttle launch is on your bucket list, kick yourself into high gear, as you just lost another opportunity to see one. Today’s launch of the space shuttle Endeavour is the second-to-the-last shuttle launch ever, as NASA prepares to retire its 30-year-old space shuttle program. This summer, the launch of the space shuttle Atlantis will officially end the program.
When Endeavour returns home on June 1, it will begin a new life as a museum piece at the California Science Center in Los Angeles. It entered service in 1992 as a replacement for the space shuttle Challenger.
