NASA decommissions Spitzer Space Telescope after 16 years of operation

NASA has decommissioned the Spitzer Space Telescope, one of its greatest observatories which has studied the universe by detecting cosmic infrared radiation for more than 16 years, the US space agency said in a statement. Spitzer, which was launched in 2003, studied some of the most distant galaxies ever detected with the light from some of the cosmic bodies travelling for billions of years to reach the telescope, NASA said.

"The advances we make across many areas in astrophysics in the future will be because of Spitzer's extraordinary legacy," Hertz added.

Spitzer, the NASA astronomers said, also found a previously undetected ring around Saturn, composed of sparse dust particles that visible-light observatories cannot see. "It's quite amazing when you lay out everything that Spitzer has done in its lifetime, from detecting asteroids in our solar system no larger than a stretch limousine to learning about some of the most distant galaxies we know of," said Michael Werner, Spitzer's project scientist.

"It wasn't in the plan to have Spitzer operating so far away from Earth, so the team has had to adapt year after year to keep the spacecraft operating," said Joseph Hunt, Spitzer project manager. "But I think overcoming that challenge has given people a great sense of pride in the mission. This mission stays with you," Hunt said.

However, as the launch of the JWST was postponed, the Spitzer mission was granted its fifth and final extension, which ended on Thursday. (Image Credits: NASA/JPL-Caltech)
