Apollo Stories

By John M. Logsdon

September 27, 2018

The circumstances that led the U.S. to undertake the Apollo 11 lunar mission 50 years ago next July, and the five landings that followed, were unique, and they won’t be repeated. Even so, space historian John M. Logsdon sees reason to anticipate that U.S. astronauts will in the next decade return to the moon.
