🌕 First Drive on Another World
-
Apollo 15 (1971) was the first mission to deploy the Lunar Roving Vehicle (LRV).
-
The rover extended astronaut range from ~1 km (walking) to over 27 km traveled.
-
Top speed reached ~8 mph (13 km/h) on the lunar surface.
-
The LRV was folded and stowed in the Lunar Module and deployed after landing.

Four Wheels, One Mission: Explore
-
The LRV weighed ~460 lbs on Earth but only ~77 lbs in lunar gravity.
-
Powered by two non-rechargeable 36-volt silver-zinc batteries.
-
Each wheel had its own electric motor for redundancy and traction.
-
Navigation used a gyro and odometer system—no GPS.

Science on Wheels
-
The rover carried cameras, tools, and the Apollo Lunar Surface Experiments Package (ALSEP).
-
Allowed astronauts to collect ~77 kg (170 lbs) of lunar samples on Apollo 15.
-
Enabled exploration of Hadley Rille, one of the most geologically significant sites visited.
-
The high-gain antenna transmitted live TV back to Earth.

🚙 Extending the Landing Zone
-
Apollo 15 astronauts traveled 17.5 miles (28 km) using the rover, over 10× farther than previous missions.
-
The rover enabled exploration up to 5 miles (8 km) from the Lunar Module.
-
Mission duration included 18+ hours of EVA, significantly expanded by rover mobility.
-
The extended range allowed access to previously unreachable terrain, including elevated regions of the Hadley-Apennine site.

Final Missions, Maximum Range
-
Apollo 17 (1972) recorded the longest rover distance: ~35.7 km (22.2 miles)
-
Mission duration included ~22 hours of EVA time using the rover
-
Improved driving techniques allowed higher speeds and better efficiency
-
Last time humans operated a vehicle on another world (to date)
