The Planetary Society is celebrating the 50th anniversary of Apollo 13, which launched on 11 April 1970. Disaster struck on 13 April, prompting the crew's infamous "Houston, we've had a problem" call for help. Learn what happened, and how NASA got the astronauts home safely on 17 April.
Apollo 13 was the 3rd attempt to land humans on the Moon and the 1st to fail. Fifty-six hours into the mission, an explosion forced the crew to abort their Moon landing and take shelter in the Lunar Module. The crew ultimately returned to Earth safely.
