Engineering film footage of the final shuttle launch

A cargo-delivery module packed with 9,400 pounds of food, equipment and science gear departed shuttle Atlantis’ payload bay on July 11, 2011 and parked at the International Space Station’s doorway for unloading.

A series of unprecedented back-to-back test-firings of a rocket engine originally developed for NASA’s space shuttle concluded earlier this month, giving engineers data crucial to achieving rapid 24-hour turnarounds planned for a U.S. military-funded reusable winged booster under construction at Boeing, government and industry officials said.
