NASA Dart succeeds in shifting asteroid's orbit

Cape Canaveral, October 11

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 space agency attempted the first test of its kind two weeks ago to see if in the future a killer rock could be nudged out of Earth’s way.

The Dart spacecraft carved a crater into the asteroid Dimorphos on September 26, hurling debris out into space and creating a comet-like trail of dust and rubble stretching several thousand miles. It took days of telescope observations to determine how much the impact altered the path of the 525-ft (160-m) asteroid around its companion, a much bigger space rock.

Before the impact, the moonlet took 11 hours and 55 minutes to circle its parent asteroid. Scientists had hoped to shave off 10 minutes, but NASA Administrator Bill Nelson said the impact altered the asteroid’s orbit by 32 minutes. — AP
