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
Space probe Image forming systems on space probes typically have a multitude of specifications, but aperture can be useful because it constrains the best diffraction limit and light gathering area. Space probe A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space. The space agencies of the USSR (now Russia and Ukraine), the United States, the European Union, Japan, China, and India have collectively launched probes to several planets and
