the scientists first planned to hit Asteroid 1950DA with an incredibly powerful nuclear weapon.But it is extremely dangerous to build such a weapon, say scientists. And it probably won,t work, says astronomer Jay Meloch.It may break the rock into pieces, he predicts, but all of these might then hit the Earth. He wants to send a small rocket to asteroid If it is equipped with advanced technology, it will burn the rock with energy from the sun. Military experts like Meloch's idea.Maybe his rocket will save the earth one day
