I read an article years ago (late 90s) that was speculating that you could change an asteroid's projection with a magnifying glass. They theorized that if you could concentrate the sun's rays on to one side of the asteroid (like burning ants), it would change the shape and ultimately cause gas to spew from the heated side...thus changing the trajectory. They were studying how you could change an asteroid bound for earth, to miss the planet.

I don't know how you could control it toward a target, but anything is possible.

I'm also old enough to completely understand Hoot's point of view on technology. It astounds me how far we've come, comparatively recently, in technological issues. And, it effects everything from Mars exploration to every day life....anyone try frying an egg in a cast iron skillet???

Finally, I don't care if I could dunk the ball on a 100 ft goal, I wouldn't want to go to Mars...even for a vacation. But, I'm glad someone does!
