Scientists doubt space elevator could ever get off the ground

So much for the idea of a space elevator. A recent report dismisses the possibility that we'll ever be able to build them out of carbon nanotubes. I guess that slingshot idea isn't so crazy after all.

Perhaps the X-Prize for the first lunar lander will do something to kick of some serious space development. Weren't we all supposed to be living in space colonies by now? They've figured out how to extract oxygen from lunar soil so how hard can it be and why does it seem appropriate to quote Robert A. Heinlein at a time like this?

I think it's going to be a long time before any more people ever walk on the moon. Former Apollo astronaut Allen Beam better keep pumping out the paintings so that we don't forget what it looks like.
