Alan Shepard's road to the Moon was not a straightforward one, so you can't blame him for wanting to have a little fun on the lunar surface. He joked in later life that he was probably better known as 'the astronaut who played golf on the Moon' than he was as the first American in space.
Nicknamed 'the Brain', Ed Mitchell was the second ever astronaut to have a PhD. On his way to and from the Moon in 1971, he took part in a psychic experiment designed to see if it was possible to transmit and receive thoughts across tens of thousands of miles.
Gemini 6A is best known for achieving the first ever rendezvous in space, a key stepping stone in the journey to the Moon. That wasn't the only 'first' it achieved, though.
All things considered, it was pretty ironic that Apollo 12 was headed for an area of the Moon known as the Ocean of Storms. Pete Conrad, Dick Gordon and Alan Bean launched into thundery skies in November 1969 and less than a minute later were struck by not one, but two bolts of lightning.
"It's your neck, and I hope you don't break it." Apollo 7 is often overlooked in the grand scheme of things, with no technological dramas to speak of. When it came to the crew, though, things were not so cleanly cut.
