Pioneer 10 Pioneer 10 Pioneer 10 (originally designated Pioneer F) is an American space probe, launched in 1972 and weighing , that completed the first mission to the planet Jupiter. Thereafter, "Pioneer 10" became the first of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System. This space exploration project was conducted by the NASA Ames Research Center in California, and the space probe was manufactured by TRW Inc. "Pioneer 10" was assembled around a hexagonal bus with a diameter parabolic dish high-gain antenna, and the spacecraft was spin stabilized around the axis of
Exploration of Jupiter moons and the ring system, discovering the volcanic activity of Io and the presence of water ice on the surface of Europa. "Ulysses" further studied Jupiter's magnetosphere in 1992 and then again in 2000. The "Cassini" probe approached the planet in 2000 and took very detailed images of its atmosphere. The "New Horizons" spacecraft passed by Jupiter in 2007 and made improved measurements of its and its satellites' parameters. The "Galileo" spacecraft was the first to have entered orbit around Jupiter, arriving in 1995 and studying the planet until 2003. During this period "Galileo" gathered a large amount of information
