A BRIEF HISTORY OF SPACE EXPLORATION
By Tim Lambert
By Tim LambertThe Beginning of Space Travel
The pioneer of space travel was a Russian, Konstantin Tsiolkowsky (1857-1935). He realized that only a rocket could provide propulsion in the near-vacuum of space. He also proposed that a rocket should be built in stages so it would dump each stage when its fuel was exhausted.
In 1926 Robert H. Goddard (1882-1945) launched the first liquid propelled rocket. Then in Germany in 1930 Johannes Winkler (1897-1947) founded a Society for Space Travel, which experimented with rockets.
During World War II a German, Wernher von Braun (1912-1977) developed a rocket that was used as a weapon against the British. The V2 rose to over 100 km above the Earth's surface. After the war ended von Braun went to the USA and continued to experiment with rockets.
Space Travel in the 1950s
The first steps into space were taken in the late 1950s. It was the Russians who first launched an artificial satellite. Sputnik I was launched on 4 October 1957. On 3 November 1957 the Russians launched a dog called Laika into space in a satellite. She was the first living creature in space.
In January 1959 the Russians launched the first space probe, Luna I. It flew within 5,000 miles of the Moon. Also in 1959 Luna 2 crashed onto the Moon. In October 1959 Luna 3 took the first photos of the dark side of the Moon.
America's first artificial satellite was Explorer 1, which was launched in January 1958.
Space Travel in the 1960s
Echo, the first communications satellite was launched in 1960.
The first man in space was a Russian, Yuri Gagarin who was launched on 12 April 1961. He made a single orbit of the Earth and landed the same day.
The first American to orbit the Earth was John Glenn on 20 February 1962 in Mercury 6.
The first woman in space was Valentina Tereshkova, who orbited the Earth 48 times between 16 and 19 June 1963.
On 18 March 1965 Aleksei Leonov became the first person to walk in space. On 16 March 1966 the first space docking took place. The US spacecraft Gemini 8 docked with an unmanned rocket.
Meanwhile the first probe to reach another planet was Mariner 2, which was launched by the Americans in August 1962. In December 1962 it flew within 22,000 miles of Venus. In 1967 Mariner 5 flew by Venus.
In 1967 a Russian probe called Venera 4 launched a capsule into the atmosphere of Venus. It analysed the atmosphere, finding it to be almost all carbon dioxide with tiny amounts of oxygen and water vapor. It also measured atmospheric pressure and measured the temperature before it stopped transmitting. (It was crushed by the atmospheric pressure). Russian probes Venera 5 and Venera 6 carried out further measurements of the atmosphere of Venus in 1969.
In 1964 the Americans launched Mariner 4. In July 1965 it flew past Mars. Mariner 6 and Mariner 7 sent back more photos of Mars in 1969. Meanwhile in 1964 Ranger 7 sent back detailed photos of the Moon before crashing into its surface. Finally in February 1966 the Russian probe Luna 9 made the first soft landing on the Moon.
However tragedy struck on 27 January 1967 when 3 astronauts Virgil I Grissom, Edward H White and Roger B Chaffee were killed in a fire in a spacecraft on the ground. The same year Russian cosmonaut Vladimir Komarov was killed when his spacecraft crashed after re-entry.
Meanwhile in 1961 President Kennedy proposed to land a man on the Moon 'before the decade is out'. The first step was Apollo 8, which was launched on 21 December 1968 carrying 3 astronauts. The spacecraft orbited the Moon 10 times and returned safely to Earth. Further preparations followed with Apollo 9 and Apollo 10 in 1969.
There were 3 astronauts on the Apollo 11 mission, Neil Armstrong, Edwin (Buzz) Aldrin and Michael Collins. The Apollo 11 mission was launched on 16 July 1969. It went into Lunar orbit on 19 July 1969. On 20 July the Lunar module, Eagle separated from the Command module, Columbia piloted by Collins. The Eagle landed on 21 July 1969 and Neil Armstrong became the first man to set foot on the Moon. The astronauts returned to Earth on 24 July 1969.
Apollo 12 landed in the Ocean of Storms in November 1969.
Space travel in the 1970s
Apollo 13 was launched in April 1970. However the mission was aborted after an oxygen tank exploded. The next mission to the Moon was Apollo 14 in February 1971. Apollo 15 followed it in July 1971. It carried a lunar roving vehicle. Apollo 16 landed on the Moon in April 1972 and finally Apollo 17 landed in December 1972.
In 1970 China launched its first satellite, Dong Fang Hong 1. The same year Japan launched its first satellite Osumi.
In 1970 Russian probe Venera 7 landed on Venus and transmitted data from the surface. Venera 8 landed on Venus in 1972. In 1974 Mariner 10 flew past Venus on its way to Mercury and took close up images of the planet. In 1975 Venera 9 went to Venus. It was followed by Venera 10 1975. Then in 1978 by Venera 11 and Venera 12 reached Venus. Pioneer Venus 1 and Pioneer Venus 2 reached Venus in 1978.
In March 1974 the American probe Mariner 10 flew past Mercury.
In December 1973 Pioneer 10 flew past Jupiter. Pioneer 11 reached Jupiter in December 1974 and it reached Saturn in September 1979.
Meanwhile on 19 April 1971 the Russians launched the first space station, Salyut I. On 14 May 1973 the USA launched a space station named Skylab.
Meanwhile in 1971 Mariner 9 photographed what seemed to be dried-up riverbeds on Mars. That suggested that the atmosphere of Mars was once thicker and there was liquid water on the planet. It raised the possibility that there was once life on Mars.
The Americans sent probes to search for evidence of life on Mars. Two probes were sent, Viking I and Viking 2. Viking I landed in July 1976 and Viking 2 landed in September 1976. Neither found any evidence of life on Mars.
Space Travel in the 1980s
In 1980 India launched a satellite named Rohini.
The first space shuttle, Columbia was launched on 12 April 1981. Challenger flew its first mission in 1983 and Discovery flew its first mission in 1984. Space shuttle Atlantis flew its first mission in 1985. Disaster struck in January 1986 when Challenger exploded in January 1986 killing all on board. Space shuttle Endeavor was built to replace Challenger and it flew its first mission in 1992.
On a brighter note the spacecraft Voyager 1 reached Saturn in 1980. In 1981 Voyager 2 flew past Saturn. Then in 1986 Voyager 2 reached Uranus. It sent back detailed images of Uranus and its rings and discovered 11 new moons. On 25 August 1989 Voyager 2 reached Neptune and sent back images. It also closely approached the largest moon of Neptune, Triton.
More probes were sent to Venus. Venera 13 and Venera 14 reached Venus in 1982. Then in 1983 Venera 15 and Venera 16 reached Venus.
Vega 1 and Vega 2 reached Venus in 1985.
Meanwhile in 1984 two men made the first untethered space walk.
Then in February 1986 the Russians launched their Mir space station. In 1988 Vladimir Titov and Musa Manarov became the first human beings to spend a year in space. Mir fell back to Earth in 2001.
