Galileo at Jupiter: The goodbye tour

Hampered by a communications antenna that never unfurled, the Galileo spacecraft became known as the plucky mission that overcame major obstacles. During more than 6 years of touring Jupiter and its four largest moons, the spacecraft managed to radio some 5 gigabytes of data to Earth, including more than 14,000 images. It has recorded towering volcanic plumes above Jupiter’s moon Io, gathered evidence that Europa might have an ocean beneath its icy carapace, and investigated the intense radiation environment near Jupiter.
