Interesting. I’d always assumed that even under a deflection scenario, some sort of physical contact would still have to be made with the object.

The underfunded NASA will be the Earth’s savior.
well,…the plan is that we have no plan.. but we could have one… still…no plan…
It would be great if somebody in government got smart enough to realize this is potentially the most serious threat around to mankind, or maybe i should say earthkind. Then they could create a new cabinet position and appoint Neil deGrasse Tyson Secretary. If anybody could solve this, I think he’s the guy.

Apparently unending wars for economic gain are more important than mankind’s survival. DRILL BABY DRILL!
Neil deGrasse Tyson is a national treasure. I’m hoping to see an upsurge in interest in science as a result of his efforts.

I really think we need to start building an asteroid defense system now. We need a couple of lightweight long range gravitational interceptors of the type Neil mentioned in this clip. They could use solar power for plasma or ion engines if we were trying to deflect an asteroid within the orbit of Mars so it wouldn’t hit us the next time round.
Smaller objects with shorter warning times would be harder to deflect. Heavier interceptors that used laser ablation or dust cloud impacts could do the job.
