People often think that the age of space exploration began with the first spaceships in the 1950s and 1960s, though in fact, astronomers had been exploring the universe long before the beginning of space flights. Galileo made the first optical telescope used for astronomy in 1609. Later scientists got a lot more information about the solar system and its planets with the help of interplanetary probes, space capsules that carry special equipment and send information back to Earth.
From the beginning of the space age, both the Soviet Union and the United States were active in the exploration of the solar system. Both countries had their own space programmes, competing with each other. Both countries sent their probes to the Moon, to Venus, Mars and, later, to Jupiter, Saturn, Uranus and Neptune. Anyhow a real breakthrough in space exploration was the beginning of manned space flights. The first manned flight took place on April 12, 1961, when Yuri Gagarin went into orbit in the Soviet Vostok 1 spaceship and proved that man could survive in space.
The second-generation Soviet spaceships Voskhod were made for a whole crew of astronauts. In 1965 Voskhod 2 made a flight which was really memorable because the copilot, Alexei Leonov, left the ship for the first time and became a space walker. He spent 10 minutes outside the spaceship in a special spacesuit.
The Soviet third-generation manned spaceship Soyuz was able of maneuvering and spending almost unlimited time in space. The next stage of space exploration was connected with the use of orbital stations. The first of them called Mir was launched in 1986.
At the same time the USA carried on its programme of the Moon exploration and in 1969 Neil Armstrong became the first man to walk on the Moon. In 1975 the USSR and the USA made the first space experiment together.
The future of space exploration seems to be connected with cooperation work in space. People’s desire1 to know more about the world around us will never be satisfied and we can get the best results if we do this hard work together.
