NASA’s Asteroid, Comet Hunting Telescope Set to Retire at End of Month

NEOWISE has taken millions of infrared measurements and studied tens of thousands of asteroids, comets, stars, galaxies, and other objects.

Key Takeaways:

NASA's NEOWISE space telescope, after more than a decade of hunting potentially hazardous near-Earth objects (NEOs), is concluding its mission and will burn up in Earth's atmosphere by early 2025 due to orbital decay.
NEOWISE made significant contributions to planetary defense, identifying thousands of NEOs, including 215 new discoveries, using its infrared capabilities.
Its successor, the dedicated NEO Surveyor, is scheduled for a 2027 launch with a $1.2 billion commitment, designed to specifically identify a high percentage of large and difficult-to-find hazardous asteroids and comets.

A NASA space telescope designed to “hunt” asteroids and comets that could pose a threat to life on Earth and orbiting spacecraft will soon burn up in orbit.

In late 2024 or early 2025, the agency’s Near-Earth Object (NEO) Wide-field Infrared Survey Explorer—or NEOWISE—is expected to come home in pieces following the conclusion of its second mission later this month. The spacecraft, which spent more than a decade collecting data on objects whizzing past the Earth and exploring ways to defend the planet and its satellites from falling rocks and ice, is now at the mercy of the sun. Soon, it will become unusable.
