Asteroids

A few weeks ago we watched NASA crash a spacecraft into a small asteroid named Dimorphos that is orbiting a larger asteroid. The best part was that it was on purpose. The project, appropriately named Double Asteroid Redirection Test or DART, is an attempt to secure knowledge and data should a “killer” asteroid ever be headed straight toward Earth. The idea is to change the trajectory of an asteroid, but to not hurt it in any way except for maybe leaving a weensy crater where the projectile—in this case a vending-maching sized craft—crashes. Sorry for the scar, Dimorphos.
