NASA's Spitzer Space Telescope’s mission concluded on Jan. 30, 2020, at the agency's Jet Propulsion Laboratory in Pasadena, California. After more than 16 years of studying the universe in infrared light, the spacecraft entered a state known as safe mode and ceased science operations.

Launched in 2003, Spitzer revealed previously hidden features of known cosmic objects and led to discoveries and insights spanning from our own solar system to nearly the edge of the universe.
