Do you really think NASA can stop an asteroid from hitting earth?
Depends on the size and the time frame from when its found to impact.
No, they can't. they didn't stopped that meteorite in Russia....
Think of the Bell, Stupid Nazis.
The day-to-day odds of an asteroid strike are minimal, but a single hit impact could spell extinction for the human race.
No. How would they stop it?
We can't even guarantee our own defense against the North Korean's infant missile program.
No.I don't think so :\
Nah ..... but Bruce Willis can........
Science is working on it. At the present time, no.
We have thousands of nukes that we could launch at an asteroid, I'm pretty sure we can knock it off, plus we have Jupiter to suck asteroids heading for Earth(Well, not all of them).
