The Galileo spacecraft orbited Jupiter for nearly 8 years and made several close flybys of Jupiter’s four largest moons. The spacecraft returned hundreds of images and a wealth of scientific information about Jupiter and its substantial moons. Galileo dispatched an atmospheric probe while on approach to Jupiter. The probe penetrated deep into the hot, hostile atmosphere of Jupiter and sent important findings back to Galileo, which relayed them to Earth. The Galileo mission overcame a serious setback when the high-gain antenna failed to deploy and the low-gain antenna had to be used for the entire mission. Ingenious workarounds in data handling and transmission timing were performed by scientists to salvage most of the planned science investigations.
