The Galileo Mission
Launched in 1989, the Galileo spacecraft arrived at Jupiter on December
7, 1995, when it fired its main engine for a successful orbit capture around
Jupiter. On that day, Galileo's atmospheric probe plunged into Jupiter's
atmosphere and relayed information on the structure and composition of the
solar system's largest planet. The spacecraft's orbiter will spend the next
two years orbiting the giant planet, studying Jupiter and its moons (encountering
one moon during each orbit), and returning a steady stream of images and
scientific data. After completing its primary mission, Galileo will then
begin its two year extended mission called the Galileo Europa Mission.
