STS-135 »

Bart Leahy, writing about the last space shuttle launch:

Five years ago today, the Space Shuttle Atlantis and the Space Shuttle program itself took its last flight into space on mission STS-135 to service the International Space Station (ISS). Since that last flight in 2011, the Shuttle orbiters have been flown off to museums across the country and NASA’s human spaceflight program has shifted to other missions and other vehicles. No other American human-rated spacecraft has been flown so often or accomplished so much.

The space shuttle wasn’t perfect, but the science done with it is stunning.
