Washington, April 17 (IANS) David French may be the guy who saves the world from an asteroid when it comes hurtling down from space.
“Using a tether somewhere between 1,000 km to 100,000 km to divert an asteroid sounds extreme but compare it to other schemes. They are all pretty far out. Other schemes include a call for painting the asteroids in order to alter how light may influence their orbit, a plan that would guide a second asteroid into the threatening one, and of course there are nukes,” he said.
