recently confirmed its DART mission, the first planetary defense test, was a success, but the agency had help from 31 citizen scientists who watched the epic event unfold from their backyards.
Armed with Unistellar telescopes, these amateur astronomers observed and tracked how Dimorphos changed brightness before, during and after impact.
This data assisted NASA scientists in measuring the mass of the dust released when the box-shaped spacecraft slammed into Dimporphos at 15,000 miles per hour, allowing them to confirm the asteroid was nudged from its orbit.
