Artist's depiction of Pioneer 10, the first spacecraft to visit 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, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.

The Galileo orbiter thus became the first artificial satellite of Jupiter. [165] [166] Most of its initial orbit was occupied transmitting the data from the probe back to Earth. When the orbiter reached its apojove on March 26, 1996, the main engine was fired again to increase the orbit from four times the radius of Jupiter to ten times. By ...

It arrived at Jupiter on December 7, 1995, via gravitational assist flybys of Venus and Earth. [40] Despite antenna problems, Galileo conducted the first asteroid flyby, discovered the first asteroid moon, was the first spacecraft to orbit Jupiter, and launched the first probe into Jupiter's atmosphere. Galileo's prime mission was a two-year ...
