Development

Lunokhod's original primary mission was to be the back-up for L3 crewed Moon expeditions and for the later Zvezda lunar base. For mission safety, weeks before the human mission on a LK lander, an LK-R uncrewed lander from the L3 lunar expedition complex and two Lunokhod automated rovers would be sent to the Moon for a preliminary study of the surface around LK-R and LK sites, to act as radio beacons for precision landings of LK-R and LK, and for a visual evaluation of the status of the site.

, a lunodrom (лунодром - Moondrome) was built. It covered an area of one hectare (120 meters by 70 meters) and was very similar to some parts of the lunar surface. It was constructed using more than 3,000 cubic meters of soil, and included 54 craters up to 16 m in diameter and around about 160 rocks of various sizes. The whole area was surrounded with bricks, painted in gray and black. It was used to analyze problems with the Lunokhod chassis and cosmonaut's skill to control one. Closed town Simferopol-28 contained the most significant tracking facility in the Soviet Union, having the largest number of antennas, the largest area, and the most personnel of any of the Soviet tracking facilities. The facility was one of a network of ten facilities which contain earth satellite vehicle tracking equipment and provide command/control for Soviet near-space civil and military events. Additionally, this facility supported all lunar programmes of the Soviet Union, in association with the Evpatoria Deep Space Tracking Facility. At least four complete vehicles were constructed, with the serial numbers 201, 203, 204 and 205.

The Lunokhod rovers were lunar vehicles formed of a tub-like compartment with a large convex lid on eight independently-powered wheels. Length was 2.3 metres. They were equipped with a cone-shaped antenna, a highly directional

Lunokhod 201

After years of secret engineering development and training, the first Lunokhod (vehicle 8ЕЛ№201) was launched on February 19, 1969. Within a few seconds the rocket disintegrated and the first Lunokhod was lost. The rest of the world did not learn of the rocket's valuable payload until years later.

This benefit allowed the 1986 designers to quickly devise a derived vehicle type for nuclear disaster recovery work. On July 15, two rovers, called STR-1, were delivered to the Chernobyl accident zone and proved useful for clearing debris, earning awards for the designers. Due to extremely high radiation levels, both STR-1 rovers eventually failed, and human workers (later named liquidators) were called in once again.
