Todays' Asteroid Test | Defending the Planet: NASA’s DART Mission
Launched in November 2021, NASA's Double Asteroid Redirection Test (DART) will be the world’s first mission to test planetary defense techniques, demonstrating one mitigation method of asteroid deflection, called kinetic impact. DART will impact the small asteroid moonlet Dimorphos, which orbits a larger companion, Didymos, in a binary asteroid system to change its orbital period. Although neither asteroid poses a threat to Earth, the collision with Dimorphos enables researchers to demonstrate the deflection technique along with several new technologies, and collect important data to enhance our modeling and predictive capabilities for asteroid deflection. Those enhancements will help us better prepare should an asteroid ever be discovered as a threat to Earth.
NASA’s Double Asteroid Redirection Test (DART), the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards, will impact its target asteroid—which poses no threat to Earth—on Monday evening, Sept. 26, 2022.
