Asteroid Terrestrial-impact Last Alert System
- ATLAS is an asteroid impact early warning system being developed by the University of Hawaii and funded by NASA.
- When ATLAS is completed in 2015, it will consist of two telescopes, 100 miles apart, which automatically scan the whole sky several times every night looking for moving objects.
- ATLAS can provide one day's warning for a 30-kiloton "town killer," a week for a 5-megaton "city killer," and three weeks for a 100-megaton "county killer".
