Moving it and landing it would probably consume more in energy costs than could be recouped by selling the material - even if it were solid gold.
It does bring up some interesting possibilities though, such as using it as a materials store and construction base to launch missions farther out into the cosmos. Especially if it has high-grade uranium ore that could serve as a localized energy source.
There are some movers and shakers who think we’re on the cusp of a serious space boom. Not sure I buy it.
I thought the same thing 5 years ago, and at the time I was working with a NASA research agency and had contact with a lot of space people. Was supposed to be right around the corner, but still nothing, relatively speaking. They were going to build a spaceport near Houston, nothing seems to have come of that. Something’s holding it up. Maybe it was osamabama.
Platinum group metals, or perhaps water will be most valuable. Some web comments recently discussed Saudi Arabia seeking a move into water as the new oil of space development.
