What a coincidence.
So while ppl were discussing the
3 months late find of a 170 kilotons explosion, another guy says this:
Here's the Right Way to Nuke an Asteroid (Sorry, Bruce Willis)
"If you've seen those movies, they're completely bogus," Lindley Johnson, the planetary defense officer at NASA headquarters, said during a media session on asteroids and the art of protecting Earth from them held at the Lunar and Planetary Science Conference taking place here this week. "That's not how we would use a nuclear explosive device to do this at all."
"We just need to change that speed by maybe a couple of centimeters per second," Johnson said. "If we do that
several years in advance, the change that occurs in the orbit as it comes around several years later to that impact point - the change in velocity will cause it to arrive early or late to the impact point. That's all we need."
Several years in advance... good luck and good night
