NEOWISE
NEOWISE (Near‑Earth Object Wide‑field Infrared Survey Explorer) is a NASA mission that repurposed the WISE spacecraft, initially launched in 2009, to detect and characterize asteroids and comets. Using infrared sensors operating at 3.4 and 4.6 µm wavelengths, NEOWISE has cataloged hundreds of thousands of minor planets—including Near‑Earth Objects—providing critical data on their sizes, orbits, and compositions.
