Apollo 12 astronaut Alan Bean descends from the lunar module Intrepid. When it reached the Ocean of Storms on November 19, 1969, Apollo 12 became the second manned mission to land on the moon. As he walked on the moon for the first time, Commander Pete Conrad famously said, "Whoopie! Man, that may have been a small one for Neil, but that's a long one for me."
