Hera Probe Sees Asteroid Pair Separately for First Time

Planetary defense is a growing concern among the scientific community, as efforts have been made to design and implement missions meant to deflect incoming threats to the Earth well in advance. In 2022, NASA intentionally collided the Double Asteroid Redirection test (DART) planetary defense spacecraft into the smaller asteroid of the binary asteroid, Didymos and Dimorphos, with the latter being the smaller one.
