Two things to mine:

Metals: platinum-group metals, nickel, iron, rare-earth elements like indium
Water i.e. hydrogen + water, i.e. rocket fuel. Water in space is important, but only if we don't solve the cheap launch problem

 ===Notes and thoughts on asteroid mining===
-First, we need to prospect them with remote sensors to find out what they're made of
-There are an estimated 500,000-1,000,000 near-earth asteroids. http://neo.jpl.nasa.gov/stats/ tracks the ones that have been discovered
-Asteroids have no atmosphere or gravitational pull, making landing and takeoff less energy-expensive than the Moon or Mars.
-We need two technologies:
-*Better, cheaper space launch
-*Better, cheaper robots
 Two things to mine:

-Two ways to mine them:
-*Send robots to intercept and harvest them
-*Nudge them into earth orbit and mine them there.
