I recently read an article on possible technology deflection strategies and technology, which described the following possible types of tech that could be used to deflect an asteroid.


The most popular one, Nuclear weapons :

This would be done by firing a nuclear equipped missiles at the asteroid to vaporize it or most of it, and the other variant of this is to drill a hole on the asteroid, drop a nuke down the hole and blow it up that way. The problems with this are as follows, one it might not completely destroy the rock / comet and would just result in multiple large fragments of space rock / ice block that would bombard the earth causing damage over a wider area, the other is, if this is done far enough away and it doesn't completely destroy the asteroid nor break it up it could accelerate the asteroid towards the earth faster with more energy, since the high pressure gasses out the back would create lots of thrust an asteroid normally wouldn't get. So it could either work great or cause even more problems.


Kinetic deflection :


This is done by slamming an object with a large mass into the asteroid to change its orbit a little, enough to cause it to miss earth.


Focused solar energy :


This one is done by focusing solar energy ( usually in the form of visible light ) into an intense beam which would be directed at the asteroids surface to vaporize material thus creating thrust to change its orbit so it would miss earth.


Rocket motor :


This one is simple, take a standard rocket motor and secure it to the asteroid / comet, ignite it and use the thrust to redirect the asteroid.

Which sure all of these sound great, you should remember the opposite is also true.

If this technology can be used to direct an asteroid away from the earth, it can also be used to direct an asteroid toward the earth.

This means, for example that two enemy countries, Japan and NK for example, they could waste each other with space rocks, and given the history of genocidal political leaders, I wouldn't put it past any country to try this

If this tech were to exist, over time it would get refined enough to where pinpoint accurate attacks would be possible.

This would mean that with the creation of asteroid deflection tech, the chances of an artificially caused man made asteroid / comet impact would be significantly greater than the chances of a natural impact.

If mankind doesn't want to be deliberately wasted by space rocks / ice , then this technology should never exist, because if it does, chances are someone will try to do damage with it.

Just some food for thought.

There is an excellent anime that tackles such an issue, its called PlaneteS.

I suggest you have a look.

Welcome back, every rose has its thorn. That goes for asteroid deflection technology. You can't stop human beings from thinking nor you can have them all to act for the good of mankind.


Interesting topic, should lead us to wonder who's regulating and governing these celestial bodies and so the universe.

Nothing governs the universe, the universe governs itself, nature is absolute.

And nature governs everything that exists within it, including humans and all the other intelligent races throughout the universe.

The sun = nature, and the sun could utterly rape us with a proton storm if it wanted to, and there would be nothing we could do about it except die, and other stars could do the same if close by ones went supernova, sterilize the entire planet in seconds lol, less than that probably, picoseconds.


Asteroids and Volcanos = nature as well, and either one of those could kill hundreds of millions of people easy.
