Lunokhod programme

• 1. Origins And Development History

  ›

  In mid-1968, engineers built a one-hectare test facility near Simferopol in Crimea. This site covered 120 meters by 70 meters and contained more than 3,000 cubic meters of soil. The ground included 54 craters up to 16 meters wide and around 160 rocks of various sizes. Workers surrounded the entire area with gray and black painted bricks. They called this place a lunodrom or Moondrome. It served as a training ground for testing Lunokhod chassis designs. Cosmonauts practiced controlling the rovers there before any mission launched. The facility supported all Soviet lunar programs alongside the Evpatoria Deep Space Tracking Facility. At least four complete vehicles were constructed with serial numbers 201, 203, 204, and 205. The original goal was to support human expeditions on the Moon. Weeks before a crewed flight, an uncrewed lander would send two automated rovers ahead. These machines acted as radio beacons for precision landings. They also provided visual evaluations of potential landing sites.

  Georgy Babakin led the design team at the Lavochkin design bureau. Alexander Kemurdzhian designed the metal chassis itself. Each rover stood about 1.3 meters high and weighed roughly 756 kilograms. The vehicle measured approximately 2.3 meters long and 1.6 meters wide. Eight wheels each had independent suspension, motors, and brakes. Electric motors sat inside pressurized containers within every wheel hub. A special fluoride-based lubricant allowed mechanical parts to function in a vacuum. Solar panels charged batteries during the lunar day while a polonium-210 heater kept components warm during nights. The lid covered the instrument bay and opened to expose the GaAs solar array. Controllers used television cameras and panoramic telephotometers to navigate. A cone-shaped antenna and helical antenna handled communications with Earth. The rover moved at speeds of approximately 2 kilometers per hour.

• 3. The Failed 1969 Launch Attempt

  ›

  Vehicle 8ЕЛ№201 launched on the 19th of February 1969 from the Baikonur Cosmodrome. Within seconds the rocket disintegrated before reaching orbit. The world did not learn details until years later when records declassified. Radioactive heat sources spread across a large region of Russia after the crash. Polonium-210 particles contaminated soil and air over hundreds of square kilometers. Engineers began work immediately on another lunar vehicle to replace the lost unit. This failure highlighted risks inherent in early space exploration technology. The incident remained secret for decades due to Cold War secrecy protocols. No public announcement occurred regarding the specific location or extent of contamination. Recovery teams could not access the site safely without risking further exposure. The loss forced a complete redesign of launch procedures for subsequent missions.

• 4. Lunokhod One Mission Operations

  ›

  Luna 17 launched on the 10th of November 1970 at 14:44:01 UTC. It entered lunar orbit on the 15th of November 1970 at 22:00 UTC. Soft landing occurred on the Sea of Rains on the 17th of November 1970 at 03:47 UTC. Lunokhod 1 descended ramps onto the surface at 06:28 UT that same day. The rover operated for 322 Earth days while traveling 10.5 kilometers total distance. It returned more than 20,000 television images and 206 high-resolution panoramas. Scientists performed twenty-five soil analyses using an X-ray fluorescence spectrometer. A penetrometer tested ground properties at 500 different locations. An urban legend claimed KGB dwarfs drove the machine but no evidence supported this claim. Five controllers sent driving commands in real time from Earth. The mission proved robotic exploration viable outside human presence.

• 5. Lunokhod Two Performance Records

  ›

  Luna 21 landed on the 15th of January 1973 inside Le Monnier crater near coordinates 25.85 degrees North latitude. Lunokhod 2 rolled down its ramp at 01:14 UT on the 16th of January 1973. This vehicle covered 42 kilometers over four months of operation. It held the record for longest extraterrestrial travel until 2014 when Mars rovers surpassed it. Three slow-scan television cameras provided navigation data to five-man teams on Earth. Four panoramic cameras captured detailed views of surrounding terrain. Instruments included a magnetometer deployed on a 2.5-meter boom extending forward. A French-supplied laser corner reflector enabled precise distance measurements from Earth. Researchers detected solar X-rays and measured local magnetic fields during operations. The rover drove into hilly upland areas and narrow rilles without difficulty. Over 80,000 television pictures were transmitted back to ground stations. Mechanical tests confirmed lunar soil properties across diverse geological features.

• 6. Post-Mission Discoveries And Legacy

  ›

  NASA's Lunar Reconnaissance Orbiter photographed tracks left by Lunokhod 1 in 2010. Albert Abdrakhimov identified both lander and rover locations using image M114185541RC. Tom Murphy and Russet McMillan detected the retroreflector signal from Apache Point Observatory on the 22nd of April 2010. Lunokhod 2 remains detectable today with sub-metre accuracy through laser ranging experiments. Richard Garriott purchased ownership rights at a Sotheby's auction in December 1993 for $246,000. He claimed private ownership despite international treaties prohibiting government claims off Earth. Garriott stated he owned the world's only object on a foreign celestial body. His gaming character Lord British became synonymous with this unique acquisition. Modern science continues using these rovers for ongoing lunar research projects. Tracks remain visible decades after missions ended due to lack of erosion processes.

• 7. Chernobyl Adaptation And Application

  ›

  The Chernobyl disaster occurred on the 26th of April 1986 when reactor four exploded. East German bulldozers weighed too much to operate safely on damaged roof sections. Human workers faced 90-second work limits due to intense ionizing radiation levels. Designers returned from retirement to create derived vehicles called STR-1. These machines used nuclear decay heat sources for internal climate control systems. Electronic components were hardened to resist partial radiation exposure during operations. Two STR-1 rovers arrived at the accident zone on the 15th of July 1986. They successfully cleared debris before failing under extreme conditions. Liquidators eventually took over manual cleanup tasks once robots stopped working. The program earned awards for designers who adapted space technology quickly. This adaptation demonstrated versatility beyond lunar exploration purposes alone. Nuclear power plants required specialized equipment unavailable through standard industrial channels.
