SIMOC and SAM featured at Sky-Lights, by science educator Dan Heim

Self-sufficient life support diagram by Dan Heim Former high school physics professor, lifelong amateur astronomer, and author of the Sky Lights, a weekly blog about things you see in the sky (and some you can’t see). Dan’s animated essays cover a wide range of disciplines including astronomy, meteorology, climatology, chemistry, physics, optics, earth & space science, and others.

This past two publications Dan has discussed Surviving in Space, with an emphasis on what it would take to make the International Space Station self-sustaining versus a habitat on the Moon or Mars. Dan writes, “Last week we looked at whether the ISS could be made totally self-sufficient and never require supply missions from Earth. The short answer was “yes” but the practical answer was “no”. However, in a colony on a moon or planet where outside resources (like water and minerals) are available, self-sufficiency is much easier.”

Trent Tresch, Kai Staats of SAM attend The Space Show

The Space Show with Dr. David Livingston

Tuesday 05 Jan 2021
Interview with Trent Tresch and Kai Staats of the Space Analog for the Moon and Mars (SAM)

Dr. David Livingston writes in summary of the interview, “We welcomed Trent Tresch back to the show and Kai Staats for the first time to discuss the SAM analog study at Biosphere 2 in Arizona. Our 65 minute discussion started by my asking Kai about his background and what specifically led him to the point of developing the SAM simulation model. Trent had experiences … that not only brought him in contact with Kai but to playing a substantial role in developing space [related projects] and the SAM.”

SIMOC featured in Planetary Society ‘Wow of the week’!

“With the SIMOC web interface, you can design your own Mars habitat and then run a simulation to find out if your astronauts would survive. By choosing life support systems, crew quarters, plants to clean the air and provide food, and more, you can learn a lot about just how complex and delicate extraterrestrial habitats are.”

In the weekly Planetary Society Downlink news update, SIMOC is featured as the Wow of the Week, Read the full post …

Title: An agent-based model for high-fidelity ECLSS and bioregenerative simulation.

Abstract: Mathematical models can combine baseline assumptions about relatively simple, real-world systems into complex simulations, providing researchers with access to otherwise difficult to build or cost prohibitive environments. An agent-based model (ABM) employs the actions and interactions of individual and collective, autonomous agents such that their behavior, when allowed to unfold over a specified time, may exhibit non-linear, dynamic, and probabilistic behavior. SIMOC (a scalable, interactive model of an off-world community) is a Python agent-based model with both a research and educational component, developed to simulate hybrid ECLSS and bioregenerative closed systems, as those considered for long-term human habitation of the Moon or Mars. The SIMOC web-based agent editor enables rapid design of new agents to approximate real-world systems. While SIMOC was built upon data for both humans and plants extracted from the NASA Baseline Assumptions and Values Document, this publication sees first application of this novel approach to modeling the growth cycle of a single plant species in a semi-sealed, controlled environment, from seed to harvest, tracking air temperature, relative humidity, PAR, carbon dioxide, water run-off and biomass accumulation.
