From O’Neill’s space colonies, to solar power satellite farms, and even prospecting retrieved near earth asteroids. In all the scenarios, one thing remained fixed – the need for space resources at the outpost. To satisfy this need, O’Neill suggested an electromagnetic railgun to deliver resources from the lunar surface, while NASA’s Asteroid Redirect Mission called for a solar electric tug to…
