Scalable Interactive Model of an Off-World Community
We will in the coming decades establish ourselves in orbit around the Moon, on the surface of Mars, and in a more distant future on moons of Jupiter and Saturn. To get there we must learn how to sustain human life in hostile environments, with limited resupply. What balance of mechanical and biological systems will be required to sustain human life in a growing, off-world habitat?
SIMOC is a novel integration of an agent-based software model, data from real-world plant physiology studies at NASA, and closed ecosystem studies universities world-wide. It is a platform for research and citizen science, providing a robust Python server and web-based, educational interface. The objective is to find the minimum complexity required to sustain human life through a combination of physico-chemical (machine) and bioregenerative (plant) systems for long duration, off-world missions.
Sound simple? Science fiction has made it look far too easy with airlocks that never require decompression, food materializing out of thin air, and terraforming in a matter of hours, not thousands of years. In the real cosmos, living off-world is far more challenging. Finding a balance of machines, plants, and humans is a complex endeavor. The slightest incongruity in waste management, power production, or CO2 scrubbing can result in catastrophic failure and abandonment of the habitat, or worse.
What is the best balance of mechanical and living life support systems? What can we learn about the resources required to effectively scale a habitat tens of millions of kilometers from home? What systems will self-sustain while others break down?
Perhaps you will find the answers …
On June 1 SIMOC went live at the National Geographic Education Resource Library!
An ASU NOW article "Interactive model simulates keeping house on Mars" accompanied the launch
With the close of May 2020, SIMOC enjoyed three full years in development, from prototype to viable, scalable, reliable platform for world-wide citizen scientist engagement.
SIMOC users select astronauts, crew quarters, life support and food rations, greenhouse and plants, solar power generation and batteries and then set the model in motion. The dashboard provides detailed monitoring of food, water, various components of air, power generation, storage, and consumption, hour by hour of the simulated mission.
At the SIMOC website, on-line tutorials prepare users for a first use of SIMOC with simulation datasets and the Next Generation Science Standards (NGSS) aligned curriculum for grades 5-8 and 9-14 available for download.
