Galileo

Robotic Outer Solar System and Small-Body Missions

Galileo was an American robotic space probe, launched by NASA on October 18, 1989, that studied the planet Jupiter and its moons as well as the asteroids Gaspra and Ida. Consisting of an orbiter and an atmospheric entry probe, it arrived at Jupiter on December 7, 1995 after gravity assist flybys of Venus and Earth, and became the first spacecraft to orbit an outer planet.
