FIA Proposes Funding Fusion for Space Propulsion

The Space subcommittee of the Fusion Industry Association, of which we are a member, has prepared a new white paper recommending government funding for a fusion propulsion development program, styled similarly to ARPA-E and DARPA.

The goal is to provide funding not just for “paper studies,” but enough funding to build real hardware and start to test fusion propulsion concepts. We want the US to remain competitive in the upcoming Deep Space Race – building a human presence on the Moon, and then Mars, and beyond.

The PFRC is directly applicable, configured as Direct Fusion Drive – a variable thrust, variable specific impulse rocket in the 1 to 10 MW range. With sufficient funding, we could build a PFRC-3 to test a fully superconducting configuration’s ability to achieve fusion-relevant plasma temperatures, and a separate propulsion testbed to develop the thrust augmentation system. This is the actual mechanism to transfer the energy from the fusion products to a rocket propellant – a fusion reactor is not a rocket until you have accelerated a propellant!
