Apollo 11 Spaceflight, First Manned Moon Landing

He then took communion privately. At this time NASA was still fighting a lawsuit brought by atheist Madalyn Murray O'Hair (who had objected to the Apollo 8 crew reading from the Book of Genesis) demanding that their astronauts refrain from religious activities while in space. As such, Aldrin chose to refrain from directly mentioning this. He had kept the plan quiet (not even mentioning it to his wife) and did not reveal it publicly for several years.
Aldrin was an elder at Webster Presbyterian Church in Webster, Texas. His communion kit was prepared by the pastor of the church, the Rev. Dean Woodruff. Aldrin described communion on the Moon and the involvement of his church and pastor in the October 1970 edition of Guideposts magazine and in his book Return to Earth. Webster Presbyterian possesses the chalice used on the Moon and commemorates the event each year on the Sunday closest to July 20.
The schedule for the mission called for the astronauts to follow the landing with a five-hour sleep period, since they had been awake since early morning. However, they elected to forgo the sleep period and begin the preparations for the EVA early, thinking that they would be unable to sleep.
