Drivin’ on the Moon
July 26, 1971: Launch of Apollo 15 and Lunar Rover
Apollo 15 was the ninth manned mission in the United States’ Apollo program, the fourth to land on the Moon, and the eighth successful manned mission. It was also the first mission on which the Lunar Roving Vehicle was used.
The mission began on July 26, 1971, and ended on August 7. At the time, NASA called it the most successful manned flight ever achieved.

Commander David Scott and Lunar Module Pilot James Irwin spent three days on the Moon, including 18½ hours outside the spacecraft on lunar extra-vehicular activity (EVA).

The crew explored the area using the first lunar rover, which allowed them to travel much farther from the Lunar Module (LM) lander than had been possible on missions without the rover. They collected 77 kilograms (170 lb) of lunar surface material.

At the same time, Command Module Pilot Alfred Worden orbited the Moon, using a Scientific Instrument Module (SIM) in the Service Module (SM) to study the lunar surface and environment in great detail with a panoramic camera, a gamma-ray spectrometer, a mapping camera, a laser altimeter, a mass spectrometer, and a lunar sub-satellite deployed at the end of Apollo 15’s stay in lunar orbit (an Apollo program first).

Seen on the back of the Rover are two SCBs mounted on the gate, along with the rake, both pairs of tongs, the extension handle with scoop probably attached, and the penetrometer. Note that the TV camera is pointed down, in the stowed position.

At the back is a rake used during the mission. Also note the red Bible atop the hand controller in the middle of the vehicle, placed there by Scott.

A close-up view of a commemorative plaque left on the Moon at the Hadley-Apennine landing site in memory of 14 NASA astronauts and USSR cosmonauts, now deceased. Their names are inscribed in alphabetical order on the plaque. The plaque was stuck in the lunar soil by Astronauts David R. Scott and James B. Irwin during their Apollo 15 lunar surface extravehicular activity. The tiny, man-like object represents the figure of a fallen astronaut/cosmonaut.
An artist’s concept showing TRW’s small lunar subsatellite being ejected into lunar orbit from the SIM bay of the Apollo 15 Service Module. The 80 pound satellite will remain in orbit a year or more, carrying scientific experiments to study space in the vicinity of the Moon. The satellite carries three experiments: S-Band Transponder; Particle Shadows/Boundary Layer Experiment; and Subsatellite Magnetometer Experiment.
