Maybe that method of construction where you heat up the ore with mirrors, then blow air into it to inflate it, then let it cool would be easier, given how little industry we have in space at the moment.
Anyways, I think its good that we're starting with something 500 tons. Big enough to be interesting, not big enough to cause a huge catastrophe if it ends up colliding with Earth. When we're better at it we can go for larger asteroids.
