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. It aimed to explore space and showcase the Soviet Union's technological and scientific abilities. Unlike programs in other countries, the Soviet space program was split among several competing groups led by important figures such as Sergei Korolev and others.

The program began studying rockets in the 1920s and grew quickly after World War II. In the 1950s, under Korolev's leadership, it achieved amazing firsts in space. The Soviet program launched the first satellite, Sputnik 1, and sent the first animal, a dog named Laika, into orbit in 1957. In 1961, the Soviet Union made history by sending the first human, Yuri Gagarin, into space.

The Soviet space program continued to set records. It sent the first woman into space, Valentina Tereshkova, in 1963, and performed the first spacewalk in 1965. The program also sent robots to explore the Moon, Venus, and Mars, landed the first rover on the Moon, and put the first space station, Salyut 1, into orbit around Earth. These achievements showed the Soviet Union's role as a leader in space exploration during the Space Race with the United States.

Origins

Further information: Soviet rocketry

The idea of space exploration began in the Russian Empire before the First World War. A Russian scientist named Konstantin Tsiolkovsky wrote important papers about space travel in the late 1800s and early 1900s. He figured out how rockets could work in space. Another engineer, Yuri Kondratyuk, came up with a smart way for spacecraft to land on the Moon and come back to Earth.

In the 1920s, the Soviet Union started testing small rockets. One of the first tests happened in 1928, when a solid fuel rocket flew for about 1,300 meters. A young engineer named Sergey Korolev became very interested in rockets and space travel. He worked with other scientists and engineers to build and test more rockets in the 1930s.

During World War II, Soviet scientists kept working on rockets. They made missiles and rocket launchers that helped protect the country. After the war, the Soviets learned from German rocket technology, which helped them build better rockets. Many German scientists and engineers helped the Soviets for a short time, but after 1947, the Soviets mostly used their own ideas and knowledge.

Sputnik and Vostok

The Soviet space program began as part of the USSR's Five-Year Plans and relied on support from the military. Although the main designer, Korolev, dreamed of space travel, he kept this secret while working on military projects. In 1951, the Soviets launched the first rocket carrying animals into space—two dogs named Dezik and Tsygan—giving them valuable experience in space medicine.

The reliable R-7 rocket, capable of carrying a large payload, became the basis for Soviet space vehicles. After the United States announced plans to launch a satellite, Soviet leader Nikita Khrushchev agreed to support the Soviet plan. This led to the launch of the first Earth-orbiting satellite, _Sputnik, and plans for crewed flights and lunar missions. The Vostok spacecraft was developed for crewed missions, with ambitions to send people to Mars in the 1960s.

Internal competition

Unlike the American space program, which had one main organization called NASA, the Soviet space program was split into several competing groups. These groups were led by different designers, such as Korolev, Yangel, Glushko, and Chelomey. Each group wanted to lead the way in space exploration, which sometimes caused delays and problems.

After the success of early missions like Sputnik Program and Vostok Program, Korolev planned big projects like the Soyuz spacecraft and the N-1 rocket for Moon missions. However, he was asked to focus on closer missions instead. Other designers also worked on important projects, and the competition continued even after Korolev’s time.

Lunar missions

The "Luna" programme achieved many firsts in space exploration. In 1959, Luna 1 was the first probe to fly by the Moon and reach its far side. Luna 2 was the first human-made object to impact the Moon, and Luna 3 sent the first photos of the Moon’s far side back to Earth.

Later missions continued to explore the Moon. In 1966, Luna 9 made the first soft landing on the lunar surface. Luna 10 became the first human-made object to orbit the Moon. Other Luna missions returned samples from the Moon and delivered rovers to explore its surface.

Venusian missions

The Venera programme achieved many important milestones in space exploration, especially in studying the planet Venus. Early missions like Venera 1, Venera 2, and Venera 3 faced challenges, but Venera 3 was the first human-made object to reach another planet when it landed on Venus in 1966. Later, Venera 7 in 1970 became the first spacecraft to send data back to Earth after landing on another planet.

Venera 9 and Venera 10 sent back the first images of Venus's surface in 1975. In 1981, Venera 13 made history by drilling into Venus's surface and taking the first color pictures, showing rocky terrain. The Vega programme started in 1984 with Vega 1 and Vega 2, which each released a balloon into Venus's atmosphere along with a lander.

Martian missions

The first Soviet mission to explore Mars, Mars 1, was launched in 1962. It aimed to fly by Mars and send back scientific data but lost contact before reaching the planet. In 1971, the Soviet Union launched Mars 2 and Mars 3. Mars 2 was the first spacecraft to reach the surface of Mars but was destroyed on impact. Mars 3 made history by achieving the first successful soft landing on Mars, but it stopped sending data after only 20 seconds.

Later missions, including Mars 4, Mars 5, Mars 6, and Mars 7, were launched between 1969 and 1973. Mars 4 and Mars 5 successfully flew by Mars and gathered important information. Unfortunately, Mars 6 and Mars 7 did not successfully land.

Salyut space station

The Salyut programme was a series of missions that established the first earth orbit space station. "Salyut" means "Salute." Initially, the Salyut stations served as research laboratories in orbit. Salyut 1, the first in the series, launched in 1971 and was primarily a civilian scientific mission.

As the Salyut program progressed, later missions like Salyut 6 and Salyut 7 improved upon earlier designs by allowing long-duration crewed missions and more complex experiments. These stations paved the way for future Soviet and later Russian space stations, including the Mir space station. The longest stay, aboard Salyut 7, was 237 days.

Program secrecy

The Soviet space program kept many details secret. Before Sputnik, the world’s first artificial satellite, the Soviet Union did not share much information about its space projects. Official announcements were vague and full of complex scientific terms, making it hard for people to understand.

The secrecy helped protect classified information and created a sense of mystery. Details about launches, cosmonauts, and spacecraft designs were often not shared until after the events. This secrecy was strongly influenced by the military, which used coded names and numbers for their projects to keep them hidden from both the public and foreign governments. Despite the secrecy, the Soviet space program always presented its achievements in a positive light, never admitting to any failures.

Projects and accomplishments

The Soviet space program worked on many exciting projects. Some of these included space stations like Almaz and Mir, satellites such as Cosmos and Sputnik, and spacecraft like Soyuz program and Vostok program. They also sent probes to study the Moon, Mars, and Venus.

The Soviet space program achieved many “firsts” in space exploration. In 1957, they launched the first satellite, Sputnik 1, into orbit. In 1961, Yuri Gagarin became the first person to travel into space. They also sent the first animals into orbit, the first person to sleep in space, the first woman into space, and the first crew to visit two space stations. These achievements showed how advanced their space technology was during that time.

Incidents, failures, and setbacks

Accidents and cover-ups

Main article: List of spaceflight-related accidents and incidents

The Soviet space program faced several serious problems and failures. One early accident happened in 1961 when a cosmonaut died in a training fire. In 1967, a Soyuz spacecraft crashed after a parachute failure, marking the first in-flight death in space travel. The Soviet Union also tried to land humans on the Moon but failed four times with their N-1 rocket, which exploded each time after launch. The United States succeeded in landing humans on the Moon first in 1969.

In 1971, a Soyuz mission to a space station suffered a problem during return, leading to the deaths of three cosmonauts—the only people to die while actually in space. There were other close calls and launch failures over the years, but the Soviet Union kept working on its space goals despite these setbacks.

Buran

The Soviet Buran program aimed to create spaceplanes similar to the US Space Shuttle. The first and only Buran flight in 1988 went well, orbiting Earth twice before landing safely. However, the heat shield could not be reused, and with changing political and military priorities, the program was stopped soon after.

Polyus satellite

The Polyus satellite was meant to be a special weapon in space, using a powerful laser. However, during its only launch in 1987, the satellite’s guidance system failed, and the mission did not go as planned.

Canceled projects

The Soviet space program had many exciting plans that never came to be. One was the Energia rocket, a powerful vehicle designed to carry very heavy payloads into space. However, without the spacecraft it was meant to launch, the project was stopped when the Soviet Union ended.

Other canceled missions included ambitious trips to Mars. Plans ranged from rovers meant to explore the Martian surface to missions designed to bring Martian samples back to Earth. There were also ideas for a mission to the asteroid belt, called Vesta, and a daring journey past Jupiter and close to the Sun, named after the famous space theorist Tsiolkovsky. Though these missions were never built, they show how far the Soviet space program wanted to go.

Interplanetary projects

Mars missions

• Heavy rover Mars 4NM was going to be launched by the abandoned N1 launcher between 1974 and 1975.
• Mars sample return mission Mars 5NM was going to be launched by a single N1 launcher in 1975.
• Mars sample return mission Mars 5M or (Mars-79) was to be double launched in parts by Proton launchers, and then joined in orbit for flight to Mars in 1979.

Vesta

The Vesta mission would have consisted of two identical double-purposed interplanetary probes to be launched in 1991. It was intended to fly-by Mars (instead of an early plan to Venus) and then study four asteroids belonging to different classes. At 4 Vesta a penetrator would be released.

Tsiolkovsky

The Tsiolkovsky mission was planned as a double-purposed deep interplanetary probe to be launched in the 1990s to make a "sling shot" flyby of Jupiter and then pass within five or seven radii of the Sun. A derivative of this spacecraft would possibly be launched toward Saturn and beyond.

Legacy

After the dissolution of the Soviet Union, Russia took over most of the Soviet space program's assets and factories. Other countries like Kazakhstan and Ukraine also inherited some space tools but needed help from each other to keep their programs going. For example, rockets built in Ukraine often needed parts from Russia and launches from Kazakhstan's Baikonur Cosmodrome. This teamwork continued through a group called the Commonwealth of Independent States' "Interstate Space Programme".
