Mattingly flew as the Command and Service Module pilot, with astronauts Charles Duke and John Young, on the Apollo 16 mision to the Moon in April 1972. Mattingly remained in lunar orbit in the Command and Service Module while Young and Scott descended to become the ninth and tenth men to walk on the Moon. Mattingly had been due to fly on the ill-fated Apollo 13 mision, but had to withdraw shortly before the flight having contracted German measles. He later flew on Space Shuttle misions 4 and 15.
