SpaceX Falcon Heavy will let us reach 15 times more asteroids than current rockets

Martin Elvis at Harvard University describes how the SpaceX Heavy allows us to reach over 40% of the asteroids where before we could reach 3%. This is because the SpaceX Heavy allows higher speeds (delta-V aka change in velocity) to be reached.

An orbitally refueled SpaceX BFR will allow the upper stage Big Falcon Spaceships to reach 9 or 10 kilometers per second. The SpaceX BFR will let us reach 80 to 90% of the asteroids.

Planetary Resources has placed its first telescope in space. They are beginning to execute their asteroid prospecting plans.

Deep Space Industries also is working to compete in mining asteroids.
