Russia may send spacecraft to knock away asteroid.
Russia is considering sending a spacecraft to a large asteroid to knock it off its path and prevent a possible collision with Earth, the head of the country’s space agency said Wednesday.
That’s cool.

wtf? perhaps Russian spacecraft are not bound by the laws of physics.

stil need to refine density estimate and find speed to get final calc of energy in joules, then momentum. density estimate is pretty low.

Why the hell do Americans still use Imperial units?
I really hate using American standards for this reason!

there was a argument for that actually somewhere, something really mundane like the retooling of the widget machines or something. thats an interesting question…
i was gonna expand on my analysis but got a little distracted. stil my goal is to end up with a momentum estimate that would give us an idea of how many Space Shuttle units we would need to actually influence the vector by 1 degree.
