Hi there!<br />I'm new here, but just finished an article on Space.com about being prepared for an asteroid impact if/when it ever happens on Earth.<br /><br />There are basically two solutions .. a plan for the cause .. and a plan for the effect. But why does the US want to spend all the money on researching how to "deflect" an impact .. over a plan to be prepared for one hitting the Earth instead?<br /><br />I can understand how much devastation an actual collision will deal to the Earth .. with it's impact, shockwaves, tsunamis, etc.. But a "planet killer" is only considered one because it will upheave a global dust storm that won't let the sunlight in. Why can't the US spend money and research on a solution to that problem instead? The US actually thinks it can spot an oncoming asteroid/comet and divert it's path? When it actually comes .. are we even going to be prepared for that?<br /><br />With a different plan ready to go (because it's about preparedness .. not utterly hypothetical about moving a space body) .. wouldn't it save plants, animals and humans from extinction? Maybe someone can think of some kind of Air Ionizers like the ones from "Sharper Image" .. but implemented on a global scale!<br /><br />I guess to me, in my opinion, I'd rather be prepared against a hurricane .. than putting all my eggs in one untested, hypothetical theory of moving a hurricane on a path around a city. And I'm not sure those US bureaucrats understand .. that there is ONLY one shot at it .. if it fails .. we all die.
