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
The Jupiter Theft and then "speak" the Cygnan musical language, and is educated by Cygnan didactic films. They discover the Cygnans have travelled for 6000 light years - and six million earth years - escaping a home planet orbiting the progenitor star of Cygnus X-1, having discovered it was on course to collapse (forming the black hole that now occupies that point in space), searching for a new home; and, to do so, have raided numerous star systems for Jupiter-mass "gas giant" planets to use as fuel. The stop-off at Sol proves to be a particularly significant one as, having found every system
