This was the closest of all the flybys of Io. The moon provided a gravity-assist necessary for Galileo ' s ultimate collision course with Jupiter. A safing event 28 minutes before closest approach prevented most of the planned data from being collected. Galileo ' s cameras were deactivated, after they had sustained irreparable radiation damage.
Galileo was an American robotic space program that studied the planet Jupiter and its moons, as well as several other Solar System bodies. Named after the Italian astronomer Galileo Galilei , the Galileo spacecraft consisted of an orbiter and an atmospheric entry probe.
During the Apollo 15 mission in 1971, astronaut David Scott demonstrated the theory of Galileo: acceleration is the same for all bodies subject to gravity on the Moon, even for a hammer and a feather. The paradox in this article considers the consequences of an experiment where one of the objects to release is electrically charged.
Galileo performed three additional flybys of Io, on August 6 and October 16, 2001 and January 17, 2002, during the Galileo Millennium Mission. Both encounters in 2001 allowed Galileo to observe Io's polar regions up-close, though imaging from the August 2001 flyby was lost due to a camera malfunction. [ 2 ]
Galileo arrived at Jupiter on December 7, 1995, after gravitational assist flybys of Venus and Earth, and became the first spacecraft to orbit an outer planet. [4] The Jet Propulsion Laboratory built the Galileo spacecraft and managed the Galileo program for NASA. West Germany's Messerschmitt-Bölkow-Blohm supplied the propulsion module.
Although the transformations are named for Galileo, it is the absolute time and space as conceived by Isaac Newton that provides their domain of definition. In essence, the Galilean transformations embody the intuitive notion of addition and subtraction of velocities as vectors .

Galileo's ship refers to two physics experiments, a thought experiment and an actual experiment, by Galileo Galilei, the 16th- and 17th-century physicist and astronomer. The experiments were created to argue the idea of a rotating Earth as opposed to a stationary Earth around which rotated the Sun , planets, and stars.
