Spitzer Telescope of NASA to retire in 2020

Spitzer Telescope of NASA to retire in 2020

Spitzer space telescope of NASA will be retired on January 30, 2020.

Spitzer is going to shut down permanently after about 16 years of exploring the cosmos in infrared light. By 2020, Spitzer space telescope will have operated for more than 11 years beyond its prime mission.

Launched into solar orbit on August 25, 2003, Spitzer was initially scheduled for a minimum 2.5-year primary mission. But the space telescope has lasted far beyond its expected lifetime.

Spitzer’s discoveries extend from our own planetary backyard, to planets around other stars, to the far reaches of the universe. And by working in collaboration with NASA’s other Great Observatories, Spitzer has helped scientists gain a more complete picture of many cosmic phenomena.

Spitzer:

NASA’s Spitzer Space Telescope was launched in 2003 to study the universe in the infrared. It is the last mission of the NASA Great Observatories program, which saw four specialized telescopes (including the Hubble Space Telescope) launched between 1990 and 2003.

The goal of the Great Observatories is to observe the universe in distinct wavelengths of light.

Spitzer focuses on the infrared band, which normally represents heat radiation from objects.

The other observatories looked at visible light (Hubble, still operational), gamma-rays (Compton Gamma-Ray Observatory, no longer operational) and X-rays (the Chandra X-Ray Observatory, still operational.)
