Nifty NASA

The Friday File: Earlier this week, NASA sent a bus-size spacecraft travelling at over 14,000/mph directly into a 525-foot-wide asteroid called Dimorphos, seven million miles away from Earth. Sounds tricky. The aim, to see if the crash alters the asteroids’ orbit. If so, this approach might save Earth from a catastrophic asteroid impact, think dinosaur extinction. Soon NASA will know if this $325 million crash project worked.
