On January 30th 2020, NASA's Spitzer Space Telescope will complete its mission.

The Spitzer Space Telescope is the final mission in NASA's Great Observatories Program - a family of four space-based observatories, each observing the Universe in a different kind of light. The other missions in the program include the visible-light Hubble Space Telescope (HST), Compton Gamma-Ray Observatory (CGRO), and the Chandra X-Ray Observatory (CXO).

Spitzer is designed to detect infrared radiation, which is primarily heat radiation.
