so this is the asteroid belt. and to it s a region of countless hundreds of thousands of asteroids, each with its own independent orbit around the sun. some of them cross earth s orbit or come very near to us. and we call those n.e.o.s, near earth objects. so one of them comes near otherwise your waste a lot of eng energy going so far out in the solar system. the redirect test. let s look at it here. yeah, good. this is it. the next one we ll say what that is, the dark mission. all right, so this is what they found. they identified this and why do you why are you so appreciative of what they found here as a model for this experiment? that s a great question. if you try to deflect a random astroid, so many things deflect it. it could hit another object.
