With the billions of dollars of accumulated wealth by corporations such as Exxon Mobile, wouldn’t it be useful to consider using some of the money to explore and mine other planets and asteroid belts for precious metals and perhaps uranium? In fact, I think that it would be useful to have a private space station for use as a staging ground in creating mining sites on other planets. The only problem is our space propulsion systems are still outdated. We need some sort of space elevator to reduce the cost of getting objects into space, after that everything should get a lot easier.
The primary reason, in my opinion, why humans have become stagnant on space technology is the end of the cold war and the past twenty or so years when there was only one superpower. Once superpowers start clashing again I expect to see a resurgence in space technology funding.
