"Using resources harvested in space is the only way to afford permanent space development," said David Gump, chief executive officer of Deep Space Industries."More than 900 new asteroids that pass near Earth are discovered every year. They can be like the Iron Range of Minnesota was for the Detroit car industry last century - a key resource located near where it was needed. In this case, metals and fuel from asteroids can expand the in-space industries of this century." Deep Space Industries' move turned the asteroid mining into a two-horse race. Some scientists are highly sceptical of the idea of asteroid mining, though new technologies have made it possible to exploit the rare metals present in the space rocks.
