92-479: Lunokhod (Russian: Луноход , IPA: [lʊnɐˈxot] , "Moonwalker") was a series of Soviet robotic lunar rovers designed to land on the Moon between 1969 and 1977. Lunokhod 1 was the first roving remote-controlled robot to land on an extraterrestrial body. The 1969 Lunokhod 1A (Lunokhod 0, Lunokhod No. 201) was destroyed during launch, the 1970 Lunokhod 1 and the 1973 Lunokhod 2 landed on
184-874: A radiometer , a photodetector (Rubin-1) for laser detection experiments, and a French-supplied laser corner reflector . Lunokhod 3 (vehicle 8ЕЛ№205) was built for a Moon landing in 1977 as Luna 25 , but never flew to the Moon due to lack of launchers and funding. It remains at the NPO Lavochkin museum. During its 322 Earth days of operations, Lunokhod 1 travelled 10.5 km (6.5 miles) and returned more than 20,000 television images and 206 high-resolution panoramas. In addition, it performed twenty-five soil analyses with its RIFMA x-ray fluorescence spectrometer and used its penetrometer at 500 different locations. Lunokhod 2 operated for about four months, covered 42 km (26 miles) of terrain, including driving into hilly upland areas and rilles . Lunokhod 2 held

The East German -built remote controlled bulldozers available to Soviet civil defense troops weighed dozens of tons – too heavy to operate on the remaining parts of the partially collapsed reactor building roof. Human labourers could not be employed to shovel debris since work shifts were limited to 90-second intervals due to intense ionizing radiation . Lunokhod designers were called back from retirement, and in two weeks rovers were made which used nuclear decay heat sources for internal rack climate control, their electronic systems were already hardened to partly resist radiation. This benefit allowed

Soviet space program The Soviet space program ( Russian : Космическая программа СССР , romanized : Kosmicheskaya programma SSSR ) was the state space program of the Soviet Union , active from 1951 until the dissolution of the Soviet Union in 1991. Contrary to its American , European , and Chinese competitors, which had their programs run under single coordinating agencies,
460-494: A letter addressed to Khrushchev, Korolev stressed the necessity of launching a "simple satellite" in order to compete with the American space effort. Plans were approved for Earth-orbiting satellites ( Sputnik ) to gain knowledge of space, and four uncrewed military reconnaissance satellites, Zenit . Further planned developments called for a crewed Earth orbit flight by and an uncrewed lunar mission at an earlier date. After

There was a success with the joint flight of Soyuz 4 and Soyuz 5 in January 1969 that tested the rendezvous, docking, and crew transfer techniques that would be used for the landing, and the LK lander was tested successfully in earth orbit. But after four uncrewed test launches of the N1 ended in failure, the program was suspended for two years and then cancelled, removing any chance of

According to
1196-675: A young Russian aircraft engineer Sergey Korolev , who would later become the de facto head of the Soviet space programme. In 1926, as an advanced student, Korolev was mentored by the famous Soviet aircraft designer Andrey Tupolev , who was a professor at his University. In 1930, while working as a lead engineer on the Tupolev TB-3 heavy bomber he became interested in the possibilities of liquid-fueled rocket engines to propel airplanes. This led to contact with Zander, and sparked his interest in space exploration and rocketry. Practical aspects built on early experiments carried out by members of
1288-512: The Apollo–Soyuz , the Soviet leadership decided a new management approach was needed, and in 1974 the N1 was canceled and Mishin was out of office. The design bureau was renamed NPO Energia with Glushko as chief designer. In contrast with the difficulty faced in its early crewed lunar programs, the USSR found significant success with its remote moon operations, achieving two historical firsts with
1380-611: The GIRD-09 , and on November 25, 1933, the Soviet's first liquid-fueled rocket GIRD-X . In 1933 GIRD was merged with GDL by the Soviet government to form the Reactive Scientific Research Institute (RNII), which brought together the best of the Soviet rocket talent, including Korolev, Langemak, Ivan Kleymyonov and former GDL engine designer Valentin Glushko . Early success of RNII included
1472-572: The Lunokhod 2 took television images of the surrounding area, then rolled down a ramp to the surface at 01:14 UT on 1973-01-16. It then took pictures of the Luna 21 lander and landing site. The rover was equipped with three slow-scan television cameras, one mounted high on the rover for navigation, which could return high resolution images at different rates—3.2, 5.7, 10.9 or 21.1 seconds per frame (not frames per second). These images were used by

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
1656-510: The 'Group for the Study of Reactive Motion' (better known by its Russian acronym " GIRD ") in the 1930s, where Zander, Korolev and other pioneers such as the Russian engineers Mikhail Tikhonravov , Leonid Dushkin , Vladimir Vetchinkin and Yuriy Pobedonostsev worked together. On August 18, 1933, the Leningrad branch of GIRD, led by Tikhonravov, launched the first hybrid propellant rocket ,

Its Interkosmos program was also notable for sending the first citizen of a country other than the United States or Soviet Union into space. The primary spaceport, Baikonur Cosmodrome , is now in Kazakhstan , which leases the facility to Russia. The theory of space exploration had
1840-566: The 1960s, the USSR's program was split between several competing design groups. Despite the successes of the Sputnik Program between 1957 and 1961 and Vostok Program between 1961 and 1964, after 1958 Korolev's OKB-1 design bureau faced increasing competition from his rival chief designers, Mikhail Yangel , Valentin Glushko , and Vladimir Chelomei . Korolev planned to move forward with the Soyuz craft and N-1 heavy booster that would be

Babakin became involved in the Soviet space program in 1949, working in Boris Chertok 's division of NII-88 on surface-to-air missiles and targeting systems. In 1952, he was part of a group transferred to Lavochkin's bureau OKB-301 to work on the intercontinental cruise missile Burya and the V-300 anti-aircraft missile. In 1960, Semyon Lavochkin died at an aircraft show (literally died in Babakin's arms), and
2208-455: The Moon (November 10, 1970 at 14:54 UTC). After two course correction manoeuvres (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 Sea of Rains on November 17, 1970 at 03:47 UTC. The lander had dual ramps from which the payload, Lunokhod 1 , could descend to the surface. At 06:28 UT the rover moved down the ramps and onto
2300-541: The Moon . In late 1963 and early 1964 the Polyot 1 and Polyot 2 satellites were launched, these were the first satellites capable of adjusting both orbital inclination and Apsis . This marked a significant step in the potential use of spacecraft in Anti-satellite warfare, as it demonstrated the potential to eventually for unmanned satellites to intercept and destroy other satellites. This would have highlighted
2392-411: The Moon by the Soviet Union as part of its Lunokhod programme. The spacecraft which carried Lunokhod 1 was named Luna 17 . Lunokhod 1 was the first roving remote-controlled robot to land on another world. 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

Zond 3 however was successful, and transmitted high quality photography from the far side of the moon. In late 1966, Luna 13 became the third spacecraft to make a soft-landing on the Moon, with
2576-557: The Moon, and Lunokhod 3 (Lunokhod No. 205, planned for 1977) was never launched. The successful missions were in operation concurrently with the Zond and Luna series of Moon flyby, orbiter and landing missions. The Lunokhods were primarily designed to support the Soviet human Moon missions during the Moon race . Instead, they were used as remote-controlled robots for exploration of
2668-502: The Moon. The rover's payload included cameras (two television and four panoramic telephotometers), a RIFMA X-ray fluorescence spectrometer , an RT-1 X-ray telescope , a PrOP odometer/penetrometer, a RV-2N radiation detector, and a TL laser retroreflector. An urban legend was spread among the Soviet Union that the Lunokhod rover was driven by a “ KGB Dwarf”, however it was never explained how supplies were stored to keep them alive for an 11-month mission. Lunokhod 2 (vehicle 8ЕЛ№204)
2760-535: The Moon. It set the goal of a lunar landing in 1967—the 50th anniversary of the October Revolution —or 1968. At one stage in the early 1960s the Soviet space program was actively developing multiple launchers and spacecraft. With the fall of Krushchev in 1964, Korolev was given complete control of the crewed program. In 1961, Valentin Bondarenko , a cosmonaut training for a crewed Vostok mission,

Mishin lacked Korolev's political authority and still faced competition from other chief designers. Under pressure, Mishin approved the launch of the Soyuz 1 flight in 1967, even though the craft had never been successfully tested on an uncrewed flight. The mission launched with known design problems and ended with

However, after 1947 the Soviets made very little use of German specialists and their influence on the future Soviet rocket program was marginal. The Soviet space program was tied to the USSR's Five-Year Plans and from the start was reliant on support from the Soviet military. Although he was "single-mindedly driven by the dream of space travel", Korolev generally kept this

The Lunokhod rovers were lunar vehicles formed of a tub-like compartment with a large convex lid on eight independently-powered wheels. They were equipped with a cone-shaped antenna, a highly directional helical antenna , television cameras , and special extendable devices to impact
3220-623: The Soviet rocket and space programs. During the 1930s, Soviet rocket technology was comparable to Germany's, but Joseph Stalin 's Great Purge severely damaged its progress. In November 1937, Kleymyonov and Langemak were arrested and later executed, Glushko and many other leading engineers were imprisoned in the Gulag . Korolev was arrested in June 1938 and sent to a forced labour camp in Kolyma in June 1939. However, due to intervention by Tupolev, he

Because of its global range and large payload of approximately five tons, the reliable R-7 was not only effective as a strategic delivery system for nuclear warheads, but also as an excellent basis for a space vehicle. The United States' announcement in July 1955 of its plan to launch a satellite during the International Geophysical Year greatly benefited Korolev in persuading Soviet leader Nikita Khrushchev to support his plans. In

Mishin remained in control of the project that became Salyut but the decision backed by Mishin to fly a three-man crew without pressure suits rather than a two-man crew with suits to Salyut 1 in 1971 proved fatal when the re-entry capsule depressurized killing the crew on their return to Earth. Mishin was removed from many projects, with Chelomey regaining control of Salyut. After working with NASA on

3864-470: The basis of a permanent crewed space station and crewed exploration of the Moon . However, Dmitry Ustinov directed him to focus on near-Earth missions using the Voskhod spacecraft , a modified Vostok, as well as on uncrewed missions to nearby planets Venus and Mars . Yangel had been Korolev's assistant but with the support of the military, he was given his own design bureau in 1954 to work primarily on
3956-603: The bureau was subsumed by Vladimir Chelomei . It became independent again in 1965, with Babakin as its chief designer. At that time, the planetary probe program was taken away from Sergei Korolev 's OKB-1 bureau and reassigned to OKB-301 due to its almost complete lack of success (not one Soviet planetary probe had succeeded since Luna 3 six years earlier). Babakin's new "NPO Lavochkin" brought improved engineering, testing and systems management to this problem, including proper bench and dynamics testing of components, something Korolev had never done. The effort began to bear fruit with

He also continued to develop his own heavy booster designs similar to Korolev's N-1 both for military applications and for cargo flights into space to build future space stations. Glushko
6164-508: The mission were to collect images of the lunar surface, examine ambient light levels to determine the feasibility of astronomical observations from the Moon, perform laser ranging experiments from Earth, observe solar X-rays, measure local magnetic fields, and study mechanical properties of the lunar surface material. The landing occurred on January 15, 1973 at 23:35 UT in Le Monnier crater (25.85 degrees N, 30.45 degrees E). After landing
6256-571: The potential use of the space program in a conflict with the US. The Soviet space program was secondary in military funding to the Strategic Rocket Forces ' ICBMs. While the West believed that Khrushchev personally ordered each new space mission for propaganda purposes, and the Soviet leader did have an unusually close relationship with Korolev and other chief designers, Khrushchev emphasized missiles rather than space exploration and
6348-574: The record for the longest distance of surface travel of any extraterrestrial vehicle until 2014. It sent back 86 panoramic images and over 80,000 television pictures. Many mechanical tests of the Moon's surface, laser ranging measurements, and other experiments were completed during this time. In 2010, nearly forty years after the 1971 loss of signal from Lunokhod 1 , the NASA Lunar Reconnaissance Orbiter photographed its tracks and final location, and researchers, using
6440-704: The robot's retroreflector using the Apache Point telescopic pulsed-laser rangefinder. Lunokhod 2 continues to be detected by lunar laser ranging experiments and its position is known to sub-metre accuracy. Ownership of Lunokhod 2 and the Luna 21 lander was sold by the Lavochkin Association for US$ 68,500 in December 1993 at a Sotheby's auction in New York (although the catalogue incorrectly lists lot 68A as Luna 17/Lunokhod 1 ). The buyer
6532-541: The rover's mechanical parts, and the electric motors, one in each wheel hub, were enclosed in pressurised containers. The rovers stood 135 centimetres (4 feet 5 inches) high and had a mass of 840 kg (1,850 lb). It was about 170 centimetres (5 feet 7 inches) long and 160 centimetres (5 feet 3 inches) wide and had eight wheels each with an independent suspension, motor and brake. The rover had two speeds, approximately 1 and 2 km/h (0.6 and 1.2 mph). The Lunokhods were transported to
6624-584: The sample determined by the X-ray fluorescence spectrometer put it in the class of weakly differentiated melanocratic alkaline gabbroids, similar to terrestrial leucitic basalt with a high potassium content. The acoustic detector returned the sounds of the spacecraft operations and the background wind, estimated to be a speed of around 0.5 m/sec wind. Venera 14 , an identical spacecraft to Venera 13, launched 5 days apart. The mission profiles were very similar, except 14 ran into issues using it's spectrometer to analyze
6716-711: The soil. Georgy Babakin Georgy Nikolayevich Babakin ( Russian : Гео́ргий Никола́евич Баба́кин ; 13 November 1914 – 3 August 1971) was a Soviet engineer working in the space program. He was Chief Designer at the Lavochkin Design Bureau from 1965 until his death. Babakin's early career was spent in radio engineering, starting with a job at the Moscow telephone company in 1930, working on an urban radio network. From 1943 to 1949, Babakin worked on radar targeting systems at
6808-476: The successful missions of Luna 9 and Venera 4 in 1966-67. Babakin died of a heart attack at the age of 57 shortly before the completion of the Mars 2 and Mars 3 spacecraft, during Lunokhod-1 mission. His bureau continued with a series of impressive successes, the first Lunar rovers , landings on Venus and robotic sample return of Moon rocks . A research division of NPO Lavochkin is named after Babakin, and
6900-412: The surface at a somewhat high speed of 17 metres per second, later analysis of the recorded radio signals revealed that the probe had survived the impact and continued transmitting a weak signal for another 23 minutes. It is believed that the spacecraft may have bounced upon impact and come to rest on its side, so the antenna was not pointed towards Earth. In 1972, Venera 8 landed on Venus and measured
6992-461: The vehicle crashing to the ground, killing Vladimir Komarov . This was the first in-flight fatality of any space program. The Soviets were beaten in sending the first crewed flight around the Moon in 1968 by Apollo 8 , but Mishin pressed ahead with development of the flawed super heavy N1 , in the hope that the Americans would have a setback, leaving enough time to make the N1 workable and land
7084-404: The world did not learn of the rocket's valuable payload until years later. The failure resulted in the radioactive heat source, polonium 210 , being spread over a large region of Russia. After the destruction of the original Lunokhod, Soviet engineers began work immediately on another lunar vehicle. Lunokhod 1 (vehicle 8ЕЛ№203) was the first of two uncrewed lunar rovers successfully landed on
7176-462: Was also provided by the Latvian pioneer of rocketry and spaceflight Friedrich Zander , including suggesting in a 1925 paper that a spacecraft traveling between two planets could be accelerated at the beginning of its trajectory and decelerated at the end of its trajectory by using the gravity of the two planets' moons – a method known as gravity assist . The first Soviet development of rockets
7268-518: Was also provided by the Ukrainian and Soviet engineer and mathematician Yuri Kondratyuk who developed the first known lunar orbit rendezvous (LOR), a key concept for landing and return spaceflight from Earth to the Moon . The LOR was later used for the plotting of the first actual human spaceflight to the Moon . Many other aspects of spaceflight and space exploration are covered in his works. Both theoretical and practical aspects of spaceflight
7360-597: Was an essential catalyst to early Soviet efforts. In 1945 and 1946 the use of German expertise was invaluable in reducing the time needed to master the intricacies of the V-2 rocket, establishing production of the R-1 rocket and enable a base for further developments. On 22 October 1946, 302 German rocket scientists and engineers, including 198 from the Zentralwerke (a total of 495 persons including family members), were deported to
7452-504: Was computer gaming entrepreneur and astronaut's son Richard Garriott , who is also known by the name of his gaming character Lord British . Garriott stated in a 2001 interview: "I purchased Lunakod 21 [ sic ] from the Russians. I am now the world's only private owner of an object on a foreign celestial body. Though there are international treaties that say no government shall lay claim to geography off planet earth, I am not
7544-602: Was continued after the collapse of the Soviet union, when the Russian federation space agency launched Luna 25 in 2023. The Venera programme marked many firsts in space exploration and explorations of Venus . Venera 1 and Venera 2 resulted in failure due to losses of contact, Venera 3 , which also lost contact, marked the first time a man-made object made contact with another planet after it impacted Venus on March 1, 1966. Venera 4 , Venera 5 , and Venera 6 performed successful atmospheric entry. In 1970 Venera 7 marked
7636-410: Was in 1921, when the Soviet military sanctioned the commencement of a small research laboratory to explore solid fuel rockets , led by Nikolai Tikhomirov , a chemical engineer, and supported by Vladimir Artemyev , a Soviet engineer. Tikhomirov had commenced studying solid and Liquid-fueled rockets in 1894, and in 1915, he lodged a patent for "self-propelled aerial and water-surface mines." In 1928
7728-432: Was killed in an endurance experiment after the chamber he was in caught on fire. The Soviet Union chose to cover up his death and continue on with the space program. Korolev died in January 1966 from complications of heart disease and severe hemorrhaging following a routine operation that uncovered colon cancer . Kerim Kerimov , who had previously served as the head of the Strategic Rocket Forces and had participated in
7820-557: Was more advanced than the Allies and a race commenced between the Soviet Union and the United States to capture and exploit the technology. Soviet rocket specialist was sent to Germany in 1945 to obtain V-2 rockets and worked with German specialists in Germany and later in the Soviet Union to understand and replicate the rocket technology. The involvement of German scientists and engineers
7912-512: Was not very interested in competing with Apollo. While the government and the Communist Party used the program's successes as propaganda tools after they occurred, systematic plans for missions based on political reasons were rare, one exception being Valentina Tereshkova , the first woman in space, on Vostok 6 in 1963. Missions were planned based on rocket availability or ad hoc reasons, rather than scientific purposes. For example,
8004-796: Was relocated to a prison for scientists and engineers in September 1940. During World War II rocketry efforts were carried out by three Soviet design bureaus . RNII continued to develop and improve solid fuel rockets, including the RS-82 and RS-132 missiles and the Katyusha rocket launcher, where Pobedonostsev and Tikhonravov continued to work on rocket design. In 1944, RNII was renamed Scientific Research Institute No 1 (NII-I) and combined with design bureau OKB-293, led by Soviet engineer Viktor Bolkhovitinov , which developed, with Aleksei Isaev , Boris Chertok , Leonid Voskresensky and Nikolay Pilyugin
8096-517: Was slow. The progress of the Apollo program alarmed the chief designers, who each advocated for his own program as the response. Multiple, overlapping designs received approval, and new proposals threatened already approved projects. Due to Korolev's "singular persistence", in August 1964—more than three years after the United States declared its intentions—the Soviet Union finally decided to compete for
8188-405: Was supplied during the lunar day by a GaAs solar array on the inside of a round hinged lid which covered the instrument bay, which would charge the batteries when opened. During the lunar nights, the lid was closed and a polonium-210 radioisotope heater unit kept the internal components at operating temperature . To be able to work in a vacuum a special fluoride-based lubricant was used for
8280-621: 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
8372-431: Was the chief rocket engine designer but he had a personal friction with Korolev and refused to develop the large single chamber cryogenic engines that Korolev needed to build heavy boosters. Chelomey benefited from the patronage of Khrushchev and in 1960 was given the plum job of developing a rocket to send a crewed vehicle around the Moon and a crewed military space station. With limited space experience, his development
8464-405: Was the second and more advanced of the two Lunokhod rovers. The launcher put the spacecraft into Earth parking orbit on January 8, 1973, followed by a translunar injection . On January 12, 1973, Luna 21 was braked into a 90 by 100 km (56 by 62 miles) lunar orbit . The Luna 21 spacecraft landed on the Moon to deploy the second Soviet lunar rover, Lunokhod 2 . The primary objectives of
