NASA's DART Mission Alters Asteroid's Shape Through Impact

Analysis of the collision between NASA's DART probe and the asteroid Dimorphos suggests that the impact may have caused significant changes to the asteroid's shape, indicating that the asteroid's surface could have reformed rather than leaving a crater. Simulations show that the asteroid is a weak rubble pile with low density, similar to other visited asteroids. These findings could provide valuable insights into the formation and characteristics of binary asteroids, informing future exploration and asteroid deflection efforts.
