examples of space probes 
Since the end of the 1950s, over 125 space probes have been launched to study the planets and satellites of the solar system.
The first probe to thrust into orbit around Jupiter (1995), Galileo is also exploring the planet’s four largest satellites.
Voyager 1 and 2 transformed our knowledge of giant planets; over 27 years after they were launched in 1977, they continue to explore the distant confines of the solar system.
The Cassini probe will study Saturn, its rings and natural satellites; Cassini is scheduled to release the Huygens probe.
Huygens was designed to study Titan, Saturn’s largest satellite.
In 1973, Pioneer-10, en route to Jupiter, became the first probe to cross the asteroid belt.
