Mars Closed-Loop Habitat Study

AstroSim v1.1+ example study — integrated food, water, and O₂ loops.

Objective

Quantify mass import reduction for a Mars habitat using greenhouse food production and ISRU water/O₂ credits versus baseline mars_habitat.

Scenario

• Closed loop: scenarios/mars_closed_loop.yaml
• Baseline: scenarios/mars_habitat.yaml

Methods

Deterministic 168 h runs with subsystem order: power → greenhouse → isru → eclss.

Reproduce

cd /home/adrianlos/projects/astrosim
pip install -e ".[dev]"
astrosim --compare scenarios/mars_closed_loop.yaml scenarios/mars_habitat.yaml
python examples/run_mars_closed_loop.py
PYTHONPATH=src python3 -m pytest tests/test_closed_loop_audit.py -q

Expected findings

• Lower eclss.food_net_import_kg vs mars_habitat
• Lower total mass.net_import_kg
• ISRU reduces eclss.o2_net_import_kg and eclss.water_net_kg
