NASA’s venerable asteroid-hunting spacecraft is not any extra.
The NEOWISE spacecraft from NASA, which surveyed 3,000 near-Earth objects equivalent to asteroids in its lifetime, burned up within the ambiance as anticipated on Friday (Nov. 1), the company introduced.
NASA confirmed the spacecraft‘s demise on X, previously Twitter, on Saturday (Nov. 2). Whereas it is the tip for NEOWISE, NASA continues to search for stray asteroids with a community of associate telescopes on Earth. A successor asteroid hunter can also launch quickly.
NEOWISE was initially launched as WISE (the Broad-field Infrared Survey Explorer) in December 2009, aboard a United Launch Alliance Delta II rocket.

WISE’s job was to scrutinize the universe in infrared (or thermal) wavelengths, and it did that for greater than a 12 months. It discovered “essentially the most luminous galaxies within the cosmos, discovering thousands and thousands of hidden black holes, and discovering the best class of star,” NASA officers wrote in a mission abstract.
The spacecraft wanted coolant to perform correctly, and when that depleted as anticipated, engineers put the spacecraft in hibernation in February 2011. With funding got here a “second act,” as NASA termed it, of the mission: now known as NEOWISE, or Close to-Earth Objects Broad-field Infrared Survey Explorer, it started searching for our bodies a lot nearer to our planet as an alternative.
The repurposed mission was due largely to luck, then-NEOWISE principal investigator Amy Mainzer, of NASA’s Jet Propulsion Laboratory in California, famous in 2019: “It turned out to be fairly good at choosing up asteroids,” she stated throughout a media briefing on the Lunar and Planetary Science Convention in The Woodlands, Texas.
The spacecraft proved adept at its new job, concluding its mission after having “surpassed all expectations and supplied huge quantities of information that the science group will use for many years to return,” Joseph Hunt, NEOWISE’s final challenge supervisor at JPL, stated when the mission’s finish was introduced in June.
NEOWISE’s demise was as a result of photo voltaic most, or the peak of the solar’s 11-year cycle of exercise. At photo voltaic most, there are extra frequent and highly effective photo voltaic flares and coronal mass ejections, which warmth up and develop Earth’s ambiance. NEOWISE had no propulsion system on board and, being in low Earth orbit, had no approach of boosting itself, so it was slowly dragged all the way down to its dying.
The successor mission, NASA’s NEO Surveyor (Close to Earth Object Surveyor), would be the first area telescope that can be particularly designed to hunt near-Earth objects in infrared wavelengths. It’s anticipated to launch in late 2027 for planetary protection, in accordance with an announcement issued by NASA earlier this 12 months.
