Lunokhod 1 was the first of two robotic lunar rovers landed on the Moon by the Soviet Union as part of its Lunokhod program. The Luna 17 spacecraft carried Lunokhod 1 to the Moon in 1970. Lunokhod 1 was the first remote-controlled robot "rover" to freely move across the surface of an astronomical object beyond the Earth. It was also the first wheeled craft on another celestial body. Although only designed for a lifetime of three lunar days (approximately three Earth months), Lunokhod 1 operated on the lunar surface for eleven lunar days (321 Earth days) and traversed a total distance of 10.54 km.

Luna 17 was launched on November 10, 1970 at 14:44:01 UTC. After reaching earth parking orbit, the final stage of Luna 17's launching rocket fired to place it into a trajectory towards the Moon (1970-11-10 at 14:54 UTC). After two course correction maneuvers (on November 12 and 14), it entered lunar orbit on November 15, 1970 at 22:00 UTC. The spacecraft soft-landed on the Moon in the Mare Imbrium (Sea of Rains) on November 17 at 03:47 UTC. It landed in western Mare Imbrium, about 60 km south of the Promontorium Heraclides. The lander had dual ramps from which the payload, Lunokhod 1, could descend to the lunar surface. At 06:28 UTC the rover moved onto the Moon's surface. Lunokhod 1 explored the surface of the Moon for about a month. Two cycloramic cameras on either side of the rover were oriented for 180° horizontal panoramas (500 × 3000 pixels). These panoramas are sometimes geometrically warped to correct for the 15° tilt of the camera.
