Galileo was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida. Named after the Italian astronomer Galileo Galilei , it consisted of an orbiter and an entry probe.
Jupiter's clouds – expected and actual results of Galileo ' s atmospheric probe mission The probe detected less lightning, less water, but stronger winds than expected. Scientists had expected to find wind speeds of up to 350 kilometers per hour (220 mph), but winds of up to 530 kilometers per hour (330 mph) were detected.
The trip from Earth to Jupiter, the probe's exploration of the Jovian atmosphere, and an orbiter tour consisting of 11 orbits of Jupiter constituted Galileo ' s primary mission. On Jupiter Arrival Day (7 December 1995), the Galileo spacecraft was given a gravity-assist from Io and then subjected to the Jupiter orbit insertion (JOI) maneuver ...
The Galileo spacecraft was the first to have entered orbit around Jupiter, arriving in 1995 and studying the planet until 2003. During this period Galileo gathered a large amount of information about the Jovian system, making close approaches to all of the four large Galilean moons and finding evidence for thin atmospheres on three of them, as ...
While multiple spacecraft have visited the Jovian moon since the 1960s, those previous two flybys were the closest any had gotten to Io's surface since the Galileo probe made numerous close flybys ...
Shortly before Galileo ' s Jupiter Orbit Insertion maneuver, the spacecraft performed the only targeted flyby of Io of its nominal mission. High-resolution images were originally planned during the encounter, but problems with the spacecraft's tape recorder, used to save data taken during encounters for later playback to Earth, required the ...
