SIMOC Phase IIIa review by Nat Geo

We have concluded our first round of review by the National Geographic Certified Educator Review Team, primary and secondary classroom instructors who test computer software products in their own classroom. We have received feedback and are already working to revise and improve SIMOC accordingly. With the close of December we anticipate a final round of reviews before diving into Phase IIIb in the first half of 2020. This final effort will take us to a release candidate for the National Geographic Society Education Resource Library.

Stay tuned!

SIMOC Phase IIIa beta is away!

SIMOC Phase III beta dashboard

We did it! Today we provided key partners with access to a beta release of SIMOC Phase IIIa. We now await their feedback, notes, and bugs in order to help us wrap the past ten months of development with the close of the year. Then we move into Phase IIIb in 2020, with the goal of improving realworld fidelity, the user Dashboard experience, and reliability over scalability across a cloud service platform. Come mid 2020, we intend to launch SIMOC a the Mational Geographic Education Resource Library.

A soft release pending

The SIMOC developers are (as I type) hard at work to wrap up loose ends and tighten the details for a soft-release to National Geographic on Monday. The Nat Geo review team will provide feedback for their experience of SIMOC and the associated educational curriculum. The SIMOC development team will then update and improve SIMOC through the month of October. This marks two and a half years in development, a team of a dozen developers in total with countless thousands of hours, and the support of individuals at NASA Johnson Space Center, NASA Kennedy, Arizona State University’s School of Earth & Space Exploration and Interplanetary Initiative, Paragon Space Development Corporation, and many other individuals from both private and public sector institutions.

We are excited for the day in which we can share SIMOC with you!

A focus on ease of deployment, user interface

The months of July and August have seen a steady improvement in the SIMOC Configuration Wizard, Dashboard, and back-end server. With new team member and developer Ezio Melotti we have focused on ease of deployment and the user interface while Iurii and Sinead continued to fine tune back-end efficiency. In a system as complex as SIMOC, we have had to rethink and retool a few of our systems, including the means by which we request and then deliver data to the front-end. In so doing, we have doubled the performance and stabilized long duration runs. SIMOC is now a proper research tool, fully function from the command line or with web interface. The simulation of a modest habitat on Mars can be completed in roughly twenty minutes on a laptop, less on a more substantial system.

Steady as she goes …

Software development does not always move from exciting milestone to major update.

Sometimes, as with sailing, you find the wind to be steady but not terribly strong, the direction consistent and the course well known. Each day you welcome the rising sun, and each night check your progress against the stars.

Steady as she goes, SIMOC is getting closer to a new home.

Beta product is running!

After more than two months focused effort on improving performance, stability, and the user interface, we have produced a launch beta product that installs on Linux, OSX, Windows, both personal computers and servers alike. The performance improvements are astounding, with 500 simulation time-steps running in just 50 seconds, or 5 hours per second. This means we can simulate roughly one full day on Mars in roughly 5 seconds. And this includes the front-end (web dashboard). If we run the server alone, it is even faster!

Stay tuned!

Update from the Development Team – April 15, 2019

Well into Phase III, the SIMOC development team is preparing for debut launches with partners National Geographic Society and the Arizona Science Center this summer.

We have completed the redesign and rebuild of the Configuration Wizard upon a highly flexible, scalable code foundation, with both a Novice and Advanced configuration. The dashboard is now being rebuilt, based upon the same, new code base that supports the Wizard.

The Agent-Based Model (ABM) is now highly programmable by means of the JSON file settings. Most important is introduction of non-linear (normal, log, sigmoid, exp) functions to describe plant growth and respiration cycles as close as possible to the real world.

With the close of May 2019 and the Phase III development cycle, SIMOC will enjoy a more robust back-end server, improved performance and stability.

Stay tuned!

SIMOC at Biosphere 2, research concluded

SIMOC at Biosphere 2 - water in, out simulation comparison, by Kai Staats

The research project is cleaned up, all equipment returned to boxes, shelves, and storage units. The barley has been dried for comparison to the original seeds, with an astounding result: 800g seeds, just 450g dry mass after fully mature plants are achieved.

SIMOC was configured to closely approximate the biomass accumulation, water retention and loss, and CO2 production for the duration of the live experiment. We consider this a success, as SIMOC is given its first non-linear functionality.

The draft paper is complete and submitted to ICES, the International Conference on Environmental Systems. Thank you University of Arizona for funding to make this possible, and the Biosphere 2 for hosting, supporting, and helping to guide this rapid-fire experiment.

SIMOC at Biosphere 2, experiment summary

SIMOC at Biosphere 2 - Kai watering barley, by Kai Staats

Three weeks at the Biosphere 2, and the barley growth experiment is nearly complete. The biomass accumulation plateaued a few days prior with overall CO2 production beginning to fall.

Overall, the experiment went very well. The data harvested is solid, from start to finish. While at moments there were what felt like major hurdles to the desired steady-state environment surrounding the experiment, one comes to realize that with 15,000 to 70,000 data points (depending upon the instrument) over 12 days, a half hour of direct sunlight on a grow chamber, or a 15 minute power loss to the fans and subsequent CO2 build-up has no affect on an overall trend.

SIMOC at Biosphere 2 - barley, by Kai Staats With three CO2 sensors, one at the outlet of each grow chamber and a third at the inlet to both chambers (as they are situated perpendicular to each other, sharing inlet air space, we found the daily fluctuations to match that of known CO2 correlations to temperature.

The data shows solid trends in all five of the parameters captured. While we came into the experiment principally interested in CO2, hoping to capture the photosynthetic draw-down of CO2 once the barley chlorophyll was activated, we learned that our seedbed was too thick, the underlying seeds remaining in a O2/CO2 respiration phase that kept the CO2 in the chambers higher than anticipated. Yet for the 30 minutes each day of direct sunlight (due to a gap in the shade cast by the LEO structure), we did see drastic reduction of CO2 in the data. We had considered full sunlight in this experiment, to invoke a higher CO2 draw-down, but knew it would be difficult to model the real-world weather (full sun, partial or full cloud cover, even a snow storm as occurred). What’s more, in a lunar or martian habitat, it is anticipated that all greenhouses will be located in lava tubes or buried beneath regolith to provide radiation protection for both the plants and humans that tend to them.

SIMOC at Biosphere 2 - barley root mass, by Kai Staats While we had originally been concerned for of our ability to capture the increase in biomass (plant structure + water retained), in fact, we were quite successful. The digital scales with 0.1g sensitivity proved more than ample to provide this data. In fact, through the careful reduction of the data we are able to discern the amount of water lost to evaporation and plant respiration (combined). Now, we are drying the total, final plant biomass (over 5Kg, having started with just 800g) to learn how much was water retained and how much was true plant structure built from carbon intake, as no nutrients were added at any point in time.

As often happens with scientific experiments, we learn something different than the anticipated outcome, and know better how to conduct the experiment the next time through.
