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
Jupiter Magnetospheric Orbiter teams for 4 of the 10 Jupiter Icy Moon Explorer (JUICE) mission instruments. Jupiter Magnetospheric Orbiter The Jupiter Magnetospheric Orbiter (木星磁気圏オービター, JMO) is a cancelled space probe proposed by the Japanese Aerospace Exploration Agency (JAXA), to undertake detailed "in situ" studies of the magnetosphere of Jupiter as a template for an astrophysical magnetised disk. The JMO was originally proposed in 2006 as the Japanese contribution to the now cancelled Europa Jupiter System Mission (EJSM). Then, it was proposed to be carried to Jupiter by the Jupiter and Trojan Asteroid Explorer (Trojan Asteroid Explorer). The discussion for the international collaboration for
