With the strain on Earth’s resources from a growing population, a budding private space industry has begun investing millions of dollars to explore the possibility of asteroid mining, the team explained. What these firms most need to harvest such rare elements as platinum is a power system to provide long-term energy for a mining operation deep in the solar system.

“We see a hard engineering problem that cannot be solved by solar plus battery,” said team members. Their solution: a reactor system using uranium-based fuel, cutting edge carbon nanotube technology and linear-actuating Stirling heat engines. Two Asteroid Atomics power systems would fit into the payload of a SpaceX Falcon 9 rocket, and according to team estimates, could function for 12 years.

After running the numbers, the team projected a cost of $40 million for one of their power systems. Given the wealth of resources in space, this kind of number might prove attractive to aspiring asteroid miners. “We hope to bring ideas of the space industry from science fiction to reality, and serve as a stepping stone for getting mankind to the final frontier,” they concluded.
