The spaceborne Spitzer observatory comprises a 0.85-meter diameter telescope and three scientific instruments capable of performing imaging and spectroscopy in the 3-180 micron wavelength regime. Spitzer has provided more than a 100-fold increase in scientific capability over previous infrared missions. Ball Aerospace in Boulder, Colo. built Spitzer's Cryogenic Telescope Assembly, which includes the scientific instruments.Spitzer was the fourth and final member of NASA's family of Great Observatories, which also includes the Chandra X-Ray Observatory, the Compton Gamma Ray Observatory, and the Hubble Space Telescope – also built, integrated and operated by Lockheed Martin. The interaction of multiple Great Observatories coordinating observations enabled a greater science return and deeper understanding as astronomical phenomena could be imaged simultaneously over many different wavelengths. Hubble, Spitzer and Chandra remain in operation.
