CAPE CANAVERAL, Fla. — A spacecraft that plowed into a small, harmless asteroid millions of miles away succeeded in shifting its orbit, NASA said Tuesday in announcing the results of its save-the-world test.
The Dart spacecraft carved a crater into the asteroid Dimorphos on Sept. 26, hurling debris out into space and creating a cometlike trail of dust and rubble stretching several thousand miles . It took consecutive nights of telescope observations from Chile and South Africa to determine how much the impact altered the path of the 525-foot asteroid around its companion, a much bigger space rock.
Apollo astronaut Rusty Schweickart, a co-founder of the nonprofit B612 Foundation, dedicated to protecting Earth from asteroid strikes, said he’s “clearly delighted, no question about that” by the results and the attention the mission has brought to asteroid deflection. “We really need to also have that warning time for a technique like this to be effective,” said mission leader Nancy Chabot of Johns Hopkins University’s Applied Physics Laboratory, which built the spacecraft and managed the $325 million mission.Launched last year, the vending machine-size Dart — short for Double Asteroid Redirection Test — was destroyed when it slammed into the asteroid 7 million miles away at 14,000 mph .
