Asteroid Terrestrial-impact Last Alert System

US

The Asteroid Terrestrial-impact Last Alert System (ATLAS) is a NASA-funded asteroid early warning system operated by the University of Hawai'i Institute for Astronomy (IfA). It is a robotic astronomical survey that uses four 0.5-meter telescopes to scan the entire visible sky several times a night, searching for potentially hazardous near-Earth objects (NEOs). ATLAS aims to provide a few weeks' to days' warning for smaller asteroids before they impact Earth, offering time for potential evacuation and protective measures. Key partners include the South African Astronomical Observatory (SAAO) and a Chilean collaboration. Associated keywords: asteroid detection, near-Earth objects, planetary defense.
