Here's a list of the missions:
* Pioneer 10 (1973) - First spacecraft to fly by Jupiter.
* Pioneer 11 (1974) - Second spacecraft to fly by Jupiter, also flew by Saturn.
* Voyager 1 (1979) - Flew by Jupiter and continued on to explore the outer solar system.
* Voyager 2 (1979) - Flew by Jupiter and continued on to explore the outer solar system.
* Ulysses (1992) - Flew by Jupiter to get a gravity assist to reach the poles of the Sun.
* Galileo (1995-2003) - Orbited Jupiter for eight years and sent a probe into the atmosphere.
* Cassini (2000) - Flew by Jupiter on its way to Saturn.
* Juno (2016-present) - Currently orbiting Jupiter and studying its atmosphere and magnetic field.
There are a few other spacecraft that may be considered "Jupiter probes," such as the New Horizons mission, which used a Jupiter flyby to gain speed on its way to Pluto. However, these missions were not primarily focused on studying Jupiter.
