Industrial Mining - Why Not Send a Manned Mission to an Asteroid and If You Like it Bring it Back?

As long as we are sending manned missions to asteroids, maybe we
should consider their commercial value as well. The mining of
asteroids could prove to be profitable some time by the end of the
next century. As human beings learn how to manipulate and control
gravity better. The mining of space asteroids may not be all that
far-fetched. Consider if you will also the science fiction authors
that write on this topic, especially Ben Bova who put out a series
called; "Asteroid Wars" - or some of Gene Roddenberry's Star Trek
episodes.On Earth we seem to have a challenge with not having enough
REE's or rare Earth elements. However if we found a solid rock of
metal in space, it might contain nothing but rare Earth metals, things
like gold, silver, titanium, etc. those are very valuable, especially
for manufacturing in space or on a lunar or Mars colony. If we had a
gravity tractor beam which one astronaut assumes that we will in the
future, we could merely take one of these asteroids after we've
inspected it to a Lagrange point of some planet and we could do the
mining there.Or, we could send a robotic mission to an asteroid, and
if the Asteroid looked like it had potential for all the materials we
needed, we can allow the robots to mine the asteroid as it made its
circuit around the solar system, and when it came back again, all of
the material could be processed and put into bags, and we merely going
pick them up. Yes, that does sound like science fiction, but that's
only because we live in the present periods and not in future periods
when all this will be possible.As the coordinator for a think tank
which operates online, we discuss these things from time to time, and
as a futurist, they are of personal interest and value to me. I hope
you agree and will please consider all this.
