... This was the result of the 1,340-pound spacecraft‘s plunging into Dimorphos at 14,000 mph. Most of the debris is probably asteroid dust, but some of DART may be in there, too. A similar video was recorded by the 1-meter Lesedi telescope in South Africa.
Mission scientsts say DART hit the asteroid less than 17 meters off center. Think about that: 17 meters off at a distance of 11 million kilometers. NASA still has the right stuff.
Now that the dust has cleared, astronomers are monitoring Dimorphos's orbit to find out whether or not it has changed in response to the strike. Even a slight shift would prove that human tech can alter an asteroid's trajectory--a possible strategy for future Planetary Defense.
