Asteroid mining has long existed as a futuristic thing, something more like science fiction and a few bold TED talks than present day technology. But a small startup named AstroForge is trying to change that. While others have tried and failed, the company believes it’s not just chasing profit but taking a step toward humanity’s long term survival. Its goal is to extract rare metals from asteroids in space, reducing our dependence on Earth’s decreasing resources and the environmental damage caused by mining.
