Double Asteroid Redirection Test (DART)
NASA is developing Double Asteroid Redirection Test (DART), the first-ever mission that will deflect a near-Earth asteroid. The DART will be built and managed by the John Hopkins Applied Physics Laboratory (APL).
It is a proposed space probe that would demonstrate the kinetic effects of crashing an impactor spacecraft into an asteroid moon. The mission is intended to test whether a spacecraft impact could successfully deflect an asteroid on a collision course with Earth.
The target for DART is an asteroid called Didymos that will have a distant approach to Earth in October 2022 and then again in 2024.
Didymos asteroid system
The Didymos asteroid system has been closely studied since 2003. It has been classified as potentially hazardous asteroid. Its Its primary body is a rocky S-type object, with composition similar to that of many asteroids.
