Did you know that earth gets hit by thousands of cosmic waste each year to protect our planet on 2/13/19 nasa announced that they to test a defence system in 2021 dart the spacecraft will go to the moonlet didymos b and it will change the speed of didymos therefore making it not hit us
Personal response I chose this article because its cool you can change astroids speed
I think it’s cool that NASA launched a space craft that will keep it from hitting earth!
