🌕 1971: The Lunar Roving Vehicle Was First Used on the Moon

The Lunar Roving Vehicle, or LRV, was a specially designed electric vehicle used by NASA during the Apollo program missions to explore the lunar surface. It was first used on the Moon during the Apollo 15 mission in 1971. The LRV was designed to allow astronauts to travel farther from their landing site and explore more of the lunar terrain than was possible on foot.

The LRV was lightweight, electrically powered, and equipped with four wheels, each with its own electric motor. It had a top speed of about 8 miles per hour (13 kilometers per hour) and could carry two astronauts, along with their tools and scientific equipment. The vehicle was controlled by a joystick and provided astronauts with greater mobility and flexibility during their lunar explorations.

During the Apollo 15 mission, astronauts David Scott and James Irwin used the LRV to travel a total of about 17 miles (27 kilometers) over the course of three separate excursions on the lunar surface. The LRV proved to be a valuable asset, significantly enhancing the scientific exploration capabilities of the Apollo missions by allowing astronauts to reach and explore areas that were previously inaccessible.

This photo is from Apollo 15. It was taken by Commander David Scott at the end of EVA-1. It shows the Lunar Module Pilot Jim Irwin with the Lunar Roving Vehicle and Mount Hadley in the background. 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, and the penetrometer.
