NASA's WISE Mission: Exceeding Expectations in Infrared Surveys
A Legacy of Stellar Observations
The Wide-field Infrared Survey Explorer (WISE) mission, launched by NASA in 2009, has revolutionized our understanding of the universe. With its cutting-edge infrared camera, WISE conducted two full-sky surveys, scanning billions of celestial objects and revealing hidden wonders.
Unprecedented Infrared Insights
WISE's infrared capabilities allowed it to penetrate interstellar dust and gas, providing unprecedented views of objects that emit energy primarily in the infrared range. This groundbreaking technology enabled the mission to uncover numerous asteroids, comets, and galaxies that were previously invisible to traditional telescopes.
NEOWISE: Tracking Celestial Threats
After completing its primary mission in 2011, WISE was reactivated in 2013 under the name NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer). NEOWISE has played a crucial role in tracking near-Earth asteroids and comets, helping scientists identify potential threats to our planet.
A Rich Legacy and a Bright Future
Nearly 15 years after its launch, WISE is nearing the end of its operational life. However, its legacy will continue to inspire future space exploration missions. NASA's upcoming NEO Surveyor mission, scheduled for launch in late 2027, will build upon WISE's success, using even more advanced infrared technology to further our understanding of near-Earth objects and the wider universe.
