Retired Captain James Lovell Jr. re-enacted the Apollo 8's live Christmas Eve broadcast from 1968. During that broadcast, astronauts read verses of Genesis from the Bible.
On Monday, Lovell and several high school students took turns reading in front of an Apollo 8 module that's housed at Chicago's Museum of Science and Industry.
Lovell says they chose Genesis because it's central to three major world religions: Christianity, Judaism and Islam.
According to NASA, millions tuned in during the original broadcast.
Lovell was a command module pilot on Apollo 8 and went on to be commander of Apollo 13.
