Added 1 new A* page:I was discussing some stuff about asteroid mining last week, and linked Wikipedia's Asteroid Mining page, but there was something on there I forgot to mention, namely that it points out that all the heavy metals that we mine from the Earth came from asteroids that hit the Earth after the surface cooled, because any heavy metals in the original stuff that formed the Earth sank to the center of the planet when it was all still molten. So all the iron and gold and stuff that we have came from asteroids that arrived later!

Well I came across this today--a Swiss dude dropped from an airplane and "flew" "over" the Grand Canyon using a jet-powered wing pack / glider sort of thing:

So not long now until we can all have personal jet packs, right?
