robotic spacecraft
A robotic spacecraft is an unmanned spacecraft, usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them.
Many artificial satellites are robotic spacecraft, as are many landers and rovers.
==History==
The first space mission, Sputnik 1, was an artificial satellite put into Earth orbit by the USSR on 4 October 1957. On 3 November 1957, the USSR orbited Sputnik 2, the first to carry a living animal into space – a dog.
Ten other countries have successfully launched orbital missions using their own vehicles: USA (1958), France (1965), Australia (1967), Japan and China (1970), the United Kingdom (1971), India (1980), Israel (1988), Iran (2009), and North Korea (2012).
