A new company, Deep Space Industries, is planning its first major public event for tomorrow. DSI plans to make its money by mining asteroids. It also claims to have developed a process for manufacturing in space.
DSI is the second company to announce its intention to mine asteroids recently. Planetary Resources did so a few months ago. One obstacle to such plans might be legal. Right now, no one has any valid legal claim to any asteroid, so it's not clear any company can simply go start mining them. Presumably, DSI, PR, and others are working on that.
