Scientists analyzing images from NASA's Double Asteroid Redirection Test (DART) mission have found the first visual evidence that small asteroids exchange rocks and dust in a slow process that reshapes their surfaces over millions of years.
Images captured in late 2022 by the DART spacecraft — an experiment that tested asteroid-deflection technology — moments before it deliberately struck the asteroid moon Dimorphos revealed faint, fan-shaped streaks across its rocky surface, according to a new study.
