- Agreed. Mining space doesn't look all that attractive, unless we
- find something useful out there that just doesn't form right under
- terrestrial conditions, or unless we can harvest large quantities
- cheaply once we're there (e.g. if we could send asteroids into earth
- orbit using solar energy and materials within the asteroid, such as
- sequestered volatiles, to provide the delta-V. I have no idea whether
- that would be practical or even possible, but I'll toss it out
- to float or sink as it will).

- Yes, this is the real key. The primary payback of the space program in
- the 60's was the knowledge we developed simply to answer the challenge.
- We developed breakthrough technologies in electronics, medicine and medical
- instrumentation, metallurgy, plastics, ceramics, nutritional science,
- computer design, and many other fields.
-
- Other ambitious challenges could conceivably yield similar results, but
- it's difficult to imagine anything else of a similar scale that would
- seize the enthusiasm and imagination of John Q. Taxpayer in quite
- the same way.
