45th Anniversary of Apollo 16 Moon Landing

On April 21st, 1972 during the 10 o'clock hour (Eastern Standard Time, USA), the Apollo 16 mission's lunar module landed on the moon's surface. Charles M. Duke Jr. and John W. Young — Americans and NASA astronauts — completed moonwalks and gathered moon-geologic samples with the help of a lunar roving vehicle, while Thomas K. Mattingly II orbited the moon in and conducted observations from a command-service module. This mission was the penultimate one for the Apollo program, with Apollo 17 being the last.
