The Galileo space probe, which launched October 18, 1989 onboard the Space Shuttle Atlantis will end its mission on the 21st of September, 2003 by plunging into Jupiter, the planet the space probe was originally sent to study nearly 14 years ago.
The Nasa Galileo Project homepage contains everything about the mission, discoveries, facts about Jupiter, its moons, the impact on Jupiter in July 1994 by comet Shoemaker-Levy and the space probe impact.
There will also be a Webcast from the Jet propulsion Institute.
The New Yorker has a nice summary on the life of the Galileo space probe, titled What Galileo Saw by Michael Benson.
