Lunokhod 2 (1973)
The Soviet Lunokhod 2 rover landed on the Moon and drove across the LeMonnier crater area, guided remotely by a ground crew. Its exact mileage stayed disputed for decades: wheel-turn counts gave 37 kilometers, later retracing on orbital images gave 42, and US-Russian talks settled near 39.
It held the off-world driving record for 41 years, until Opportunity passed it in July 2014.
The dispute over its true distance illustrates how uncertain odometry is on another world, an uncertainty Perseverance's longer drives now inherit.
Perseverance took a title Lunokhod 2 held for four decades, and both missions faced the gap between commanded and actual terrain.
