Flew two Apollo era flights. On Apollo 12, he, Charles Conrad (aka Pete) and Richard Gordon conducted the second trip to the moon. Bean was the Lunar Module Pilot and as such accompanied Conrad to land and walk on the surface of the moon. They brought back lunar rocks and pieces of the Surveyor 3 probe. As the Commander of Skylab 2, he flew with Jack Lousma and Owen Garriott and set a duration record of 59 days in space.
This has got to be the most spectacular sight of the whole flight. You can't see the Earth. It's black just like the space. [on witnessing the sun eclipsed by the earth from the moon]
