Today marks one year since Atlantis roared on Launch Pad 39A en route to the International Space Station. It was the last of the 135 launches in the history of the space shuttle program. Here is an amazing video that shows them all at the same time.

This video gets me teary every time I watch it. NASA's work never ceases to amaze me. Make sure to watch it at full screen in high definition.

Here's our own homage to the 30 years of the shuttle: all the missions merged into one single video. [McLean FahnestockThanks Stephen!]
