Galileo is a NASA spacecraft mission to Jupiter, launched October 18,
1989, and designed to study the planet's atmosphere, satellites and
surrounding magnetosphere for two years, starting December 1995.
This mission will be the first to make direct measurements from an
instrumented probe within Jupiter's atmosphere, and the first to conduct
long-term observations of the planet and its magnetosphere and satellites
from orbit around Jupiter. It is already the first to encounter an
asteroid, and to photograph an asteroid's moon.
The Galileo Europa Mission (GEM) is a highly focused follow-on to
Galileo's Jupiter system exploration, and a precursor for future missions
to two of Jupiter's moons, Europa and Io. GEM will conduct a detailed
study of Europa over 14 months, then plunge repeatedly through the Io
Plasma Torus to reach volcanic Io.
