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
Lucy (spacecraft) Lucy (spacecraft) Lucy is a planned NASA space probe that will tour five Jupiter trojans, asteroids which share Jupiter's orbit around the Sun, orbiting either ahead of or behind the planet. All will be fly-by missions. On 4 January 2017, "Lucy" was chosen, along with the "Psyche" mission, as NASA's Discovery Program missions 13 and 14 respectively.
