The Space Shuttle Challenger Accident Investigation

America’s first space shuttle launched on this day 35 years ago as the reusable flying machine, Columbia, lifted off from Kennedy Space Center with John Young and Bob Crippen aboard.

The last remaining external fuel tank built for the space shuttle program but never flew will depart its factory in New Orleans on Tuesday for a long sea voyage to the California Science Center in Los Angeles.

Watch the shuttle Atlantis’ backflip, which occurred five years ago today, before docking to the International Space Station.
