On December 7th in 1995, the unmanned Galileo spacecraft arrived at the planet Jupiter on its mission to study the planet and its moons. It had been launched six years earlier by the Space Shuttle Atlantis on October 18th of 1989.
The Galileo was an American robotic space probe which consisted of an orbiter and an entry probe. It was named after the Italian astronomer Galileo Galilei. Called the father of observational astronomy, Galilei studied speed, velocity, gravity and free fall, inertia, projectile motion and the principle of relativity. He also improved military compasses and the telescope that he used to observe the four largest satellites of Jupiter.
The U. S. Jet Propulsion Laboratory built the Galileo spacecraft and managed the Galileo program for the National Aeronautics and Space Administration, NASA. Its propulsion unit was supplied by West Germany’s aerospace manufacturer Messerschmitt-Bölkow-Blohm. The Ames Research Center of NASA managed the atmospheric probe that was built by the Hughes Aircraft company. The combined mass of the orbiter and probe was 2,562 kilograms and had a height of 6.15 meters.
The nuclear powered Galileo orbited Jupiter from 1995 to 2003. After ten months of operating and sending information to Earth, the Galileo was intentionally destroyed in Jupiter’s atmosphere on the 21st of September in 2003. Its successor, Juno, part of the New Frontiers program, entered the polar orbit of Jupiter on the 5th of July in 2016. The Juno is powered by three solar panels, the largest ever deployed on a planetary probe at the time of its launching.
