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
Jupiter trojan will then return to the vicinity of Earth for a gravity assist to take it to Jupiter's Trojan cloud where it will visit 617 Patroclus. The Japanese space agency has proposed the OKEANOS solar sail for the late 2020s to either analyse a Trojan asteroid "in situ" or to perform a sample-return mission. Jupiter trojan The Jupiter trojans, commonly called Trojan asteroids or simply Trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each Trojan librates around one of Jupiter's two stable Lagrange points: ', lying 60° ahead of the
