# Thread: Deep Impact

1. I can't find the exact mass of the flyby portion, but did find the spacecraft launch mass to be 1020 kg. So, roughly, the mass of the imactor and flyby combined at most is only 2.5 times that of the impactor portion alone.

Instead of a mosquito running into a 747, it would be like 2 and a half mosquitoes running into a 747.

You should really go back and fix it.

Wouldn't it be more correct to write "uneasier"?

All this means is that we don't know a few hings about comets and that's why we're running the experiment.

Meanwhile, after you get through fixing your post per ToSeek's advice and the BB's rules, read up on conservation of momentum. You might find out not only why the comet will continue in its orbit no matter what happens, but also why, in movies, so many explosions that are depicted as occurring in space are obviously unreal.

There, that was easy. 8)

According to the NASA website here, the flyby's 650kg. Pretty darned good guesstimate with the 1/2.5 mosquito analogy! =D> =D>

I'm wondering how many at Nasa would love to say "Ramming Speed" after launching the impactor.

I know I would.

LOL.

Is this strictly a guy thing? It seems guys love to blow things up. I know I do. I suspect genetics are involved.

I wonder how many scientists becomes scientists not only to blow things up, but to get paid for it too!!.

To think of all the trouble I used to get into for making explosive devices, and all I had to say was "It was in the interest of science". Oh wait, I did try that. It didn't work. Never mind..

Regarding the antimatter comet theory, there's already a thread here that discusses it. Basically, it's a crock.
