We are in danger of being smashed to bits by a large asteroid. That doesn't make me very happy at all. It's a good thing we have over 7 billion human brains to tap into for a solution to this problem.There are a bunch of ideas out there on how to deal with a threatening asteroid. Some of the ideas are pretty cool because, well they just are. Like blowing one up with a nuke. It would be cool to get out that telescope and watch it happen. I mean, what a show!
Then there are other methods that aren't so spectacular as nuking. They may be safer methods, but they don't have the stuff that makes for a good show. I guess you can't have everything.
I have an idea on how to deal with a threatening asteroid. Here it is below. If you have an idea, that has not already been thought of, please post it in the comments section. The very fate of the Earth, and mankind may depend on it.
My asteroid deflection system, the Tethered Body Assemblies:
Have a probe capture two small asteroids of the right size. One being smaller than the other. Have the probe tie the asteroids together using a line made from carbon nano-tubes, or other appropriate material. The attaching mechanism, at the end of the tethers, would have efficient thrusters for control.
Now you have two different size, small bodies, tethered with a cord of the proper length. The length, or separation of the two small bodies, would be determined by the size of the object being deflected, and other factors.
Using your thrusters, you would have the two tethered small bodies, TB for short, rendezvous with the threatening asteroid. The TB would be going very fast (speed to be determined). Make it so that the smaller of the two TB's impacts the threatening asteroid first. Because it is tethered to the larger TB, the larger TB starts to whip around the threatening asteroid in an arch like motion. The smaller TB is dragged across the surface of the threatening asteroid. The threatening asteroid's path is effected by the force of the large TB being pulled by the tether and the resulting arch like motion, and the small TB being dragged across the threatening asteroid's surface. The final action on the path of the threatening asteroid being when the large TB is pulled in to impact the threatening asteroid.
The threatening asteroid's path is effected by:
1. The impact of the first TB.
2. The off-center tension/pulling of the cord by the larger TB.
3. The dragging/friction of the smaller TB, across the surface.
4. The impact of the larger TB
The asteroid is deflected, and the Earth is saved!
You could make a bunch of the Tethered Body Assemblies, and hit the threatening asteroid multiple times for added effect. It seems that they would be less expensive than laser based asteroid deflection systems, and more effective.
You got any ideas? Post them below and vote on the one you like best. You may save humanity.
