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
NASA Uranus orbiter and probe NASA Uranus orbiter and probe A Uranus orbiter and probe is a mission concept for study of the planet Uranus. It was first recommended to NASA in 2011 by its Planetary Science Decadal Survey 2013–2022. NASA evaluated in 2017 twenty different mission designs submitted by the scientific community, considering mission trades, trajectories, and the technology required for specific objectives. Because of planet position and alignments, Neptune was dropped in favor of Uranus. If funded, the proposed mission would launch in the 2020s with launch-windows of 21 days every year. The survey listed the Uranus orbiter and probe as the third
