The fourth American manned mission to land on the moon was launched on this day in history.
Apollo 15 was launched from Cape Canaveral in Florida on July 26th, 1971 aboard a Saturn V rocket. The crew was David Scott, James Irwin, and Alfred Worden.
It was the first Apollo mission to include a lunar rover, a short-range vehicle that allowed astronauts to drive across the surface of the Moon. Aside from a greater surface area covered thanks to the rover, the astronauts ran several scientific studies, collected lunar samples and more as part of the mission. In all the crew spent a little over a combined 19 hours on the lunar surface.
All 3 astronauts returned to Earth successfully on August 7th. Two more manned Apollo missions to the moon would take place after Apollo 15.
