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 Magnetospheric Orbiter teams for 4 of the 10 Jupiter Icy Moon Explorer (JUICE) mission instruments. Jupiter Magnetospheric Orbiter The Jupiter Magnetospheric Orbiter (木星磁気圏オービター, JMO) is a cancelled space probe proposed by the Japanese Aerospace Exploration Agency (JAXA), to undertake detailed "in situ" studies of the magnetosphere of Jupiter as a template for an astrophysical magnetised disk. The JMO was originally proposed in 2006 as the Japanese contribution to the now cancelled Europa Jupiter System Mission (EJSM). Then, it was proposed to be carried to Jupiter by the Jupiter and Trojan Asteroid Explorer (Trojan Asteroid Explorer). The discussion for the international collaboration for
