The NEOWISE mission continued to use the spacecraft from NASA ’s WISE mission, which ran from late 2009 to 2011 .

It continued investigating near- Earth objects such as asteroids and comets even after running out of its cryogenic coolant until February 2011 .

After two years of hibernation, the mission reactivated and continued operating from December 2013 until 2024 .

NEOWISE had taken more than 1.5 million infrared measurements of 44,000 different objects in the solar system.

This included about 1,600 discoveries of near- Earth objects.

Despite the mission’s contributions to science and planetary defense, it was decommissioned in August 2024 .
