Thought you guys might be interested in this bit of news i read today


A meteor was the cause of an enormous explosion in the atmosphere last year, NASA has announced.

The blast was the second largest of its kind in 30 years, and the biggest since the fireball over Chelyabinsk in Russia six years ago.

Huge explosion over Russia

I reckon it was Lewis hidden Vodka stash that went up somewhere in outback Siberia.

May as well, because unlike Poles, Russians do not know how to make good vodka...

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
