Space Shuttle Endeavour

A year ago this week, Space Shuttle Endeavour was on launchpad 39A waiting for her final mission. The first launch attempt of STS-134 scheduled for April 29th at 3:47pm was scrubbed at 12:20pm due to problems with two heaters on one of the orbiter’s auxiliary power units. Two weeks later, she launched on May 16th at 8:56 am.

Commander Mark Kelly, Pilot Gregory H. Johnson, and Mission Specialists Michael Fincke, Roberto Vittori, Andrew Feustel, and Gregory Chamitoff delivered the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station.

She landed for the final time on June 1st at 2:35am completing a mission lasting 15 days, 17 hours, 38 minutes, and 51 seconds and traveling 6,510,221 miles.

Here are pictures of her on the launchpad taken April 28th.
