Be careful. Be very careful.
You are feeding Sassy with misinformation. In order for John Glenn to have walked on the Moon he would have needed very, very, very long legs. Legs about a quarter of a million miles long, in fact. Not only that, he would have to have been brought back from retirement.
John Glenn was the first US astronaut in space (although Sassy will probably tell us that no American has ever been into space). He never escaped Earth orbit, nor did he ever leave his capsule.
My most sincere apologies for my error of fact!
Charles Duke became a committed Christian after his Apollo 16 flight, and is active in prison ministry.
After his retirement as a Colonel in 1972,
James Irwin (Apollo 15) spent the next 20 years as a "Goodwill Ambassador for the Prince of Peace", stating that "Jesus walking on the earth is more important than man walking on the moon". He frequently spoke about how his experiences in space had made God more real to him than before.
Beginning in 1973, Irwin led several expeditions to Mount Ararat, Turkey, in search of the remains of Noah's Ark. In 1982, he was injured during the descent and had to be transported down the mountain on horseback. In More Than Earthlings, Irwin wrote expressing his view that the Genesis creation narrative was real, literal history.
I knew that at least one astronaut who had walked on the moon became a minister of religion.
