from left to right:

• living inside the spaceship to reduce the need for construction/habitats
• solar panels (800 m² per person gives 80 kWpeak)
• bagger + furnace (not sketched) for excavating hydrated minerals and heating them in an oven to release water
• some greenhouses (recycled water for watering is displayed)
