Exploration of Jupiter Exploration of Jupiter The exploration of Jupiter has been conducted via close observations by automated spacecraft. It began with the arrival of "Pioneer 10" into the Jovian system in 1973, and, , has continued with eight further spacecraft missions. All of these missions were undertaken by the National Aeronautics and Space Administration (NASA), and all but two have been flybys that take detailed observations without the probe landing or entering orbit. These probes make Jupiter the most visited of the Solar System's outer planets as all missions to the outer Solar System have used Jupiter flybys to reduce fuel requirements
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
