The design and operation of the three Rover vehicles that reached the Moon

Space exploration has been driven by rockets and spacecraft of various designs, but it has also included wheeled vehicles.

During NASA's Apollo program, which put humans on the Moon, three Lunar Roving Vehicles (LRVs) were used. These were very lightweight, four-wheeled vehicles with electric motors. Popularly known as "Lunar Rovers," they were used in the Apollo 15 (LRV-1, July 1971), Apollo 16 (LRV-2, April 1972), and Apollo 17 (LRV-3, December 1972) missions.

The LRVs were specifically designed for lunar gravity. They weighed 209 kg and were folded into the lunar descent modules, measuring 90 cm high, 150 cm wide, and 170 cm long before deployment. When deployed, they measured 3.1 meters long and 1.8 meters wide. They could reach a maximum speed of 14 km/h and their batteries provided an autonomy of 78 hours.

The three LRVs were designed by the aerospace company Boeing, in collaboration with General Motors. Since wheels with rubber tires would have posed a risk of punctures on the lunar surface, the wheels were made with a steel mesh, with titanium components for contact with the surface. Each wheel had a diameter of 81.8 centimeters. Between the three vehicles, they traveled a total of 90.8 kilometers across the lunar surface, never straying more than 9.8 kilometers from the landing site.

Three years ago I already told you here about the places where these LRVs were abandoned, which to this day remains the most distant and also the most exclusive wheeled vehicle parking lot. This Friday, Jared Owen published one of his always interesting videos on the design and operation of these vehicles, explaining in detail how they were deployed and how they were used on the Moon:
