Check it out, Buzz Aldrin took communion on the moon:

“In the radio blackout, I opened the little plastic packages which contained the bread and the wine. I poured the wine into the chalice our church had given me. In the one-sixth gravity of the moon, the wine slowly curled and gracefully came up the side of the cup. Then I read the Scripture, ‘I am the vine, you are the branches. Whosoever abides in me will bring forth much fruit. Apart from me you can do nothing.’ I had intended to read my communion passage back to earth, but at the last minute [they] had requested that I not do this. NASA was already embroiled in a legal battle with Madelyn Murray O’Hare, the celebrated opponent of religion, over the Apollo 8 crew reading from Genesis while orbiting the moon at Christmas. I agreed reluctantly. …I ate the tiny Host and swallowed the wine. I gave thanks for the intelligence and spirit that had brought two young pilots to the Sea of Tranquility. It was interesting for me to think: the very first liquid ever poured on the moon, and the very first food eaten there, were the communion elements.”
