Fun fact: the first religious ritual to take place on a heavenly body other than earth was during Apollo 11, when Buzz Aldrin, an ordained Presbyterian elder, took communion in the lander shortly before stepping on the lunar surface.
Did I once scrub through the entire audio of Apollo 11 to find the moment Aldrin asked listeners to "give thanks," which was right before he took communion (and possibly signal to his home church in Texas to join him in the ritual)?
