Making the MMOST of ISRU for the Moon and Mars

Here’s a novel way to produce both oxygen and steel in situ on the Moon and eventually on Mars. Under a NASA SBIR Phase II Sequential Contract, Pioneer Astronautics along with team members Honeybee Robotics and the Colorado School of Mines are developing what they call Moon to Mars Oxygen and Steel Technology (MMOST), an integrated system to produce metallic iron/steel and oxygen from processed lunar regolith.

In a presentation at a meeting of the Lunar Surface Innovation Consortium last month, Mark Berggren of Pioneer Astronautics gave an update on the team’s efforts. Progress has been made on several key processes under development as part of the overall manufacturing flow. Output products will include oxygen for either life support or rocket fuel oxidizer and metallic iron for additive manufacturing of lunar steel components.

The immediate next steps for the MMOST development program will be continual refinement of each process module, protocols for minimization of power requirements, demonstration of LOXIE in a vacuum environment and then optimization of mass, volume and power specifications for a scaled-up system toward flight readiness hardware.

Potential follow-on activities may include a robotic sub-scale LOXIE lunar flight experiment that could be sent to the Moon via a Commercial Lunar Payload Services (CLPS) lander. As part of the Artemis program crews could possibly demonstrate a pilot unit to validate manufacturing in the lunar environment. If successful, a full scale MMOST commercial system could come next in support of lunar base operations as part of a cis-lunar economy.

Modeling a water based cis-lunar economy

Most forward looking space planners believe that lunar water will be one of the primary resources that will drive cis-lunar economic activities. But can the growth of a water-based ecosystem be modelled to make future revenue predictions? Using a new methodology that combines System Dynamics with scenario planning a team of researchers in Japan and France has done just that by quantifying the parameters of two scenarios likely to unfold in the near future: a lunar settlement called “Moonopolis” and a long term exploration effort named “Apollo 2.0”. The analysis was just published in Acta Astronautica in a paper entitled The cis-lunar ecosystem — A systems model and scenarios of the resource industry and its impact.

System Dynamics (SD) is time-based modeling to frame, understand, and discuss dynamic behavior of complex systems. Originally developed in the 1950s to improve a company’s understanding of industrial processes, SD is used in both the public and private sectors for policy analysis and to drive strategy.

In the study, the authors* find that three factors are essential for success: government support for R&D, private capital re-investment, and continued growth of the telecom satellite industry in geosynchronous orbit. With these stipulations a cis-lunar economy of $32 billion is projected after 20 years.

Key insights gleaned from this novel holistic model reveal the dynamics of a space resource economy and the interaction of of key technical, policy and socioeconomic variables along with their uncertainties to make future projections.

Incidentally, the authors partnered with a Japan-based company called iSpace on the study which has its own plans for a lunar city called Moon Valley. They are projecting that 1000 people could be living there by 2040.
