NEOWISE: Legacy of NASA’s Asteroid-Hunting Telescope

Описание: The NEOWISE mission, NASA’s asteroid-hunting space telescope, is retiring in summer 2024 after over a decade of discovering, tracking, and characterizing near-Earth objects (NEOs) — asteroids and comets that come close to Earth’s orbit. Without a propulsion system to boost its orbit, NEOWISE, which is short for Near-Earth Object Wide-field Infrared Survey Explorer, is expected to re-enter Earth’s atmosphere and burn up in the coming months. In this video, mission leaders explain how NEOWISE has revolutionized our understanding of the solar system, better prepared us to predict potential impact events, and paved the way for a new mission: NASA’s Near-Earth Object Surveyor.

Originally launched in 2009 as WISE (Wide-field Infrared Survey Explorer), the telescope completed its primary mission to conduct an all-sky survey in the infrared spectrum. The spacecraft detected asteroids, stars, and some of the faintest galaxies in space, and then was put into hibernation in 2011. NASA re-awakened it in 2013, launching its second career and giving rise to its modified name, NEOWISE. On Aug. 8, 2024, mission controllers at NASA’s Jet Propulsion Laboratory will send a command to once again put the spacecraft into hibernation before its re-entry, expected in late 2024 or early 2025.
