Are you interested in modern-day mining? Are you also a pretty big space nerd? You could have the best of both worlds and begin a fine career in asteroid mining! Being an asteroid miner may sound like a sci-fi concept, but by 2025, it may be a real job listing. Several companies are working towards eventually mining asteroids and some comets for raw materials. These minerals, including iron, nickel, titanium, and even water, could then be taken back to Earth or used in space for space-construction purposes.
