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
Sundiver (space mission) Sundiver (space mission) Sundiver is a proposed space mission to crash a probe into the Sun, sending back data to Earth before burning up. It has been proposed as a design study by the Australian Academy of Science's National Committee for Space Science as a Flagship mission to kick-start an Australian space program. The design study is proposed as a five-year study from 2011-2015 with a complement of 10 PhDs, budgeted at a cost of $10 M (Australian), leading to a Go/NoGo Decision in 2015. The mission would be comparable in its close approach to the Sun to the NASA
