Galileo's mission was to better explore Jupiter and its interior. Its conical structure near the bottom of the spacecraft conceals the atmospheric probe which entered the Gaseous Giants atmosphere in 1995. Its exterior cover of black and gold fabric was developed in order to protect it from the extreme vacuum of interplanetary space. In order to run the spacecraft on a minimal amount of fuel, scientists devised a very complex trajectory. This trajectory takes Galileo by Venus and then around the Earth twice to gain enough kinetic energy to propel it to Jupiter.
In 1995 the atmospheric probe plunged in to Jupiter's atmosphere and sent data to the orbiter and in turn transmitted the data to Earth. Even though there was a malfunction of the antenna's deployment mechanism, data was still able to be transferred to scientists here on Earth. The orbiter servers many purposes, some of which include studying some of the major satellites of the planet, and measuring the atmosphere and magnetosphere. Galileo's mission answered many scientists questions as well as brought up of ton of new ones.
