NASA to test solar-powered propulsion for asteroid defense

The Double Asteroid Redirection Test (DART) mission will employ roll-out solar arrays and an electric propulsion system to redirect Earthbound asteroids. The DART craft, which was carried out of orbit last month by a SpaceX Falcon 9 rocket, intentionally crashes itself into an oncoming asteroid, using kinetic energy to redirect the asteroid’s trajectory. It is designed to be propelled by…
