Spitzer Space Telescope

The Spitzer Space Telescope makes many discoveries by detecting and imaging the Universe's infrared radiation. Launched in 2003, it is one of NASA's four Great Observatories, the others being the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and Hubble. Each of these spacecraft was designed to measure different parts of the electromagnetic spectrum.

Unlike the others, Spitzer orbits the Sun, not the Earth. The satellite's route takes it further and further from the Earth's heat interference. Spitzer's main mission ended in 2009 when its coolant finally ran out, though its 'warm mission' continues.
