Space probes : Survey the space!

Space probes are used to explore space. They are unmanned computer-controlled spacecraft Most
probes are ‘fly-bys’, which spend just a few days passing their target and beaming data back to Earth, although some actually land on the surface of planets, moons and asteroids.

Galileo space probe
The Galileo space probe has circled Jupiter for more than six years. It arrived there in 1995
and dropped a small probe into Jupiter’s clouds. Galileo sent back pictures of the planet and its largest moons. Through this, it was discovered that two of them may have water hidden under ice thicker than the Arctic ice on Earth. When Galileo has finished sending back pictures of Jupiter and its moons, it will plunge into Jupiter’s swirling clouds.

Amazing
In January 2005 the Huygens probe. launched from the Cassini spacecraft, landed on Saturn’s moon. Titan. It is the furthest from Earth a spacecraft has ever landed, about 1.3 billion km away.

Voyagers
The Voyagers are a pair of unmanned us space probes. launched to explore the outer planets. The Voyagers used the 'slingshot' of Jupiter's gravity to hurl them on towards Saturn. The probes revealed volcanoes on 10. one of Jupiter's Galileon moons. Voyager 2 also  found ten Unknown moons around Uranus and six unknown moons and three rings around Neptune Voyager 2 will beam bock data until 2020 as it travels beyond the edges of the Solar System.

On 5 September 1977, Voyager 1 was launched aboard the Titan III/Centaur. It was sent to join its sister spacecraft, the Voyager , on a missions to the outer planets.
