Religion in Space

After touching down on the Moon, American astronaut and Presbyterian Buzz Aldrin administered communion to himself, a plan he'd kept secret so as not to attract the attention of the despotic atheist Madalyn Murray O'Hair.

O'Hair, it turns out, had filed a lawsuit in 1968 after astonauts on Apollo 8 had read from Genesis. The court rejected O'Hair's complaint, stating that its jurisdiction in matters of separation of church and state did not extend into outer space (Source: Chaikin, Andrew. A Man On The Moon. p 204).
