If you are as serious about space exploration as I and many of the rest of us here are, then it is not enough to go and click "support" on facebook or make some online petition. You should read up on the subject some, a few good books would be "Interplanetary fight: an introduction to astronautics" by Arthur C. Clarke, "The Case for Mars" by Robert Zubrin, "The Starflight handbook" by Eugene Mallove, and for some really optimistic reading "The giant leap" by Adrian Berry.
To that I would like to add
Mining The Sky by J. S. Lewis.
When it comes to accessible resources and surface area, the small bodies dwarf their larger cousins. Lewis makes a good case against planetary chauvinism.
I've been an asteroid guy for a long time, probably more years than 8603103a.
However, at this time, even the NEOs are hard to reach.
Yes, there are some that infrequently come near the earth. But what delta V does it take?
8603103a, if you want to contribute, study calculus, trig, physics. Here are two orbital mechanics books:
Fundamentals of Astrodynamics by Bate, Mueller & White (very inexpensive).
Orbital Mechanics by Prussing and Conway.
Some fundamental concepts: Delta V, Launch Windows, The Rocket Equation.
I believe there are some preliminary efforts we need to make before the asteroids become accessible.
