Lagrange point or into orbit around the Moon. A chemical rocket would get the equipment to the asteroid and provide assistance to stabilize it. The rocket might also carry highly efficient ion engines to the asteroid, which would then be powered by solar panels as to save on weight and cost. All studies show these techniques are not just science fiction, rather they could be put into action in as little as 12 years without having to develop new technologies.
realize that they contain Trillions of dollars worth of minerals, then you also realize that we need to develop the methods for capturing asteroids for our use. In these cases, using an asteroid for a base is just a huge bonus while developing the technology to fully utilize asteroids on an economic scale.
