Apollo 15

Launched on July 26, 1971, Apollo 15 featured a three-day stay on the Moon's surface and the use of the lunar rover to travel a distance of almost 28 km. There were more extensive geology investigations on three EVAs. There was also a deep space EVA.

The Apollo 15 astronauts were David R. Scott, Alfred J. Worden and James B. Irwin. This was the first of the three advanced missions in the Apollo program and featured the use of the lunar rover for the first time. They were to survey and sample an area in the Hadley-Apennine region. They collected samples from the maria, the Apennine highlands, and an area along the Hadley Rille.

A number of experiments were deployed on the lunar surface.
