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
Galileo Probe Galileo Probe The "Galileo" Probe was an atmospheric-entry probe carried by the main "Galileo" spacecraft to Jupiter, where it directly entered a hot spot and returned data from the planet. The probe was built by Hughes Aircraft Company at its El Segundo, California plant, measured about across. Inside the probe's heat shield, the scientific instruments were protected from extreme heat and pressure during its high-speed journey into the Jovian atmosphere, entering at per second. It entered Jupiter on December 7 1995, 22:04 UTC and stopped functioning 23:01 UTC, 57 minutes and 36 seconds later. The probe was released from the
