1957: Sputnik satellite blasts into space. A Russian satellite has been launched into space - the first man-made object ever to leave the Earth's atmosphere. The Russian news agency, Tass, said the satellite Sputnik was now 560 miles (900 kilometres) above the Earth and circling it every hour-and-a-half. Scientists predict the metal sphere will eventually burn up in the atmosphere but they hope it will send important data back to Earth before doing so.
