A first-of-its-kind asteroid deflection experiment lifted off overnight from Vandenberg Space Force Base in California. SpaceX launched NASA’s DART mission on a Falcon 9 rocket at 1:21 a.m. EST Wednesday (0621 GMT; 10:21 p.m. PST Tuesday) on a 10-month mission to collide with a near-Earth asteroid, proving a technique that could protect Earth from a future threat from space.
