For centuries, people dreamed about leaving Earth and travelling to other worlds. Then, in 1957, the Soviet Union made the first small step into space by launching a small satellite, called Sputnik. The Space Age had begun.<\/p>\n
During the last 60 years, unmanned probes have been sent towards all of the planets in the Solar System, as well as many satellites, asteroids and comets. Spacecraft have soft-landed on half a dozen worlds, while rovers have driven over the surfaces of the Moon and Mars. The Sun has also been explored in great detail by a fleet of spacecraft. <\/p>\n
Many space observatories, such as the Hubble Space Telescope, have been launched to look at the distant Universe. They have sent back some amazing pictures taken in visible light.
