I just keep thinking of Katey Sagal running around on a spaceship yelling "Hal!" "Hal!"

I dont know if the scale is correct but the meteor that hit earth and killed the dinosaurs was ~ 100 Million Megaton ~ 0.1 Billion Megaton or 200 weak then the one that might hit mars. The difference is Mars is a bit smaller which has less Gs and no atmosphere which would cause bigger explosion but nowhere near as big as if it hit earth.

I have not taken a physics course in awhile but using E = 1/2MV^2, and the Discovery News velocity estimate of 35 miles/s (~54km/s) the estimate of 20 billion megatons gives a mass of 5.7 * 10^10 metric tons or 57 billion tons.

For comparison that puts it over half the mass of the moon. If I did the math correctly (which I cannot say for sure that I did) that makes me a bit skeptical of the estimate.

Edited for clarity.

yeah, the moon weights around 81,100,000,000,000,000,000 tons i think

I like all the people saying we couldn't deflect it. But they don't realize that due to the distance it covers, even a small bump could push it thousands of miles off course.

I for one, would like to just sit back and watch it happen. Then we can see what it could possibly do to a planet like ours, and then we can get to work on our anti-asteroid gear..... thumb.gif

The problem is NOT the actual act of deflecting it. It's getting a ship/rocket/drone funded(biggest issue by far), designed, and built in time to get it there when we don't even have concrete details yet.

There's really nothing I want more than this to happen. The only way it could be better is if it crashed near Curiosity, simply because that thing can film/stream HD video. Who wouldn't want a video of a 50km-wide rock slamming into a planet biggrin.gif

Or at least I hope the mars image will see it. Anything really. I want pics biggrin.gif

I agree. I want to see some Universe destruction. The only bad thing to come out of this event is the B-rated Hollycrap movies that would be made.
