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
Saturn Atmospheric Entry Probe Saturn Atmospheric Entry Probe The Saturn Atmospheric Entry Probe is a mission concept under study since 2010, where a robotic spacecraft would deliver a single probe into Saturn to study its atmosphere. Due to the orbits and relative positions of Saturn and Earth, launch is proposed for August 30, 2027 for a June 22, 2034 arrival. The mission is under review in order to compete for funding by NASA's New Frontiers Program. To unveil the processes of outer planet formation and Solar System evolution, detailed studies of the composition, structure, and dynamics of giant planet interiors and atmospheres would be
