Galileo Space Mission

The Ultraviolet Spectrometer was an important instrument in making the trip possible. It works at the electromegnetic range of UV between 40 nm and 180 nm.

The space mission of Galileo was named after the renaissance astronomer Galileo.

The detector on the UV Spectrometer is the photomultiplyer tube.It takes radiation that enters the tube and strikes the cathode, this causes the emission of several electrons, the elctrons being to accelerate. Eventually the electrons gather in the anode and can be measured to test the UV radiation in Jupiter's atmosphere.

The purpose of the Galileo Space Mission was to explore Jupiter, it's moons, and it's atmosphere. This was the first time we had ever sent a spacecraft to Jupiter in September of 2003. Along the way, Galileo took pictures of the very first asteroid to have a moon of it's own. The mission gave us clues to help us better understand the formation of suns and planets billions of years ago. Galileo took lots of pictures of Jupiter and it's moons. The moons are very different, one is made of ice and another is desert like. Galileo uncovered so much inforamtion and traveled so far, the voyage lasted a total of six years!

The UV Spectrometer looks a lot like a computer with lenses for detecting UV and radiation.
