NASA's DART spacecraft slammed into the asteroid Dimorphos at a spot between two boulders during last September's first test of a planetary defense system, sending debris hurtling into space and changing the rocky oblong-shaped object's path a bit more than previously calculated.

"The DART test was phenomenally successful. We now know that we have a viable technique for potentially preventing an asteroid impact if one day we had the need to," said planetary scientist Terik Daly of the Johns Hopkins University Applied Physics Laboratory in Maryland, lead author of one of the DART studies published in the journal Nature.
"We were trying to change the amount of time that it took for Dimorphos to orbit around Didymos by colliding head-on with Dimorphos," said Northern Arizona University planetary scientist Cristina Thomas, lead author of another of the studies published in Nature.
