NASA's DART spacecraft is about to slam into an asteroid

Using algorithms previously used for military missile targeting, DART will impact Dimorphos, which is an orbiting moonlet of the larger asteroid Didymos.

Dimorphos is about 525 feet (160 m) in diameter, while its parent asteroid is almost a half-mile (0.8 kilometres) wide. The moonlet Dimorphos orbits Didymos every 12 hours.
