up because we have no end of weaponry to do this. but that's not the wisest path. all engineering calculations tell us. because if you blow something up, while we're good at blowing it up, we're not as good as knowing where the pieces will end up. so it's safer and it's more controlled to deflect an asteroid from harm's way. and what we found is a double asteroid, so the d.a. in the d.a.r.t. stands for double asteroid redirect test. and we know the orbit of the moon. that's about the size of a football stadium. and it's in orbit around its host asteroid. and we know that orbit with good enough precision that if we slam our spacecraft into the moon, it will alter that orbit, and it should alter it in a measurable way. and if we succeed at that, it's like, oh, yes, now we have methods and tools to deflect asteroids that we may one day
