Manufacturer: The Galileo Spacecraft
was manufactured by the Jet Propulsion Laboratory,
Messerschmitt-Bölkow-Blohm, General Electric, and the
Hughes Aircraft Company.
Mission Duration: Galileo was planned to have a mission duration of around 8 years, but was kept in operation for 13 years, 11 months, and 3 days, until it was destroyed in a controlled impact with Jupiter on September 21, 2003.
Destination: Galileo's destination was Jupiter and its moons, which it orbitted for 7 years, 9 months, and 13 days.
