Yes Phil, you are correct. Communications and earth observation in orbit are
great examples of space applications that have succeeded. But, they are also
things that we've already done. I admit that there is probably more to explore
and learn here, near to us, but I was really thinking about more distant space
exploration. Our planet is pretty boring from the perspective that we are here,
and get get around on it to see what's on the surface. Subsurface exploration
in the Ocean (I'd like to know a lot more about those now underwater cities that
appear to have been buried by catastrophic floods from ICE age ice dams
breaking), and other deep earth observations would be a good thing to learn more
about what is going on without planet and how we are affecting.
Higher orbit or distant communications systems are exciting. A repeater or two
on the moon for example would be something that we might try and be ready to
provide should a moon mission come up on the horizon.

Actually, there's one space application that has proved quite
commercially viable: communications. Commercial earth resources
satellites are a distant second. I can't think of anything else.
Exploration for its own sake is never going to be commercially viable.
There has to be some short-term economic payoff. There's a long history
of those who have become rich in some other industry funding an earth
expedition out of personal interest, but the cost of space flight is
still far too high for this to extend to space. It means that the
funding of space exploration will have to remain the province of
governments for the time being. There's just no payoff for commercial
investment, at least not yet.
