Humanity’s first attempt to purposely change the motion of asteroid was a success. The DART mission shows that NASA is trying to be ready for whatever the universe throws at us in future.
After 10 months flying in space, NASA's DART mission successfully impacted its asteroid target last week - the agency's first attempt to move an asteroid in space.
There was a huge weakness in our asteroid defense system when only one of the hemispheres was covered by telescopes that constantly scan the sky. Now NASA funded two more telescopes in the southern hemisphere.
