Life Support System

Water From Cold Traps

The water obtained by the outpost on Malapert Mountain will be transfered to the Sundial Explorer every 28 days.

WATER TANK

Water for crew: 1197 kg Water for electrolysis: 445 kg 80% recycling potential, tank must hold 1110 kg

CREW (28 days Report)

Oxygen consumption: 210 kg

Water consumption: 1197 kg

Nitrogen need: 210 kg

CO2 Scrub Tank 530 kg Grey Water performed by solar energy

Recycling

The grey hygiene water, urine, respiration steam from the crew and waste water from fuel cells of rovers are recycled. Recycling efficiency is 80%.

Hydrogen Fuel Cells For Rovers

The hydrogen and oxygen, which are produced by electrolysis, will be delivered to the rovers, to be used in fuel cells, which are more efficient than batteries. Fuel cells produce water as a waste product, which can be used further.

Comments by David Nixon

+ Compact and well-planned habitat accommodation.

+ Clever chassis unfolding methodology.

+ Good life support system approach (though harvesting water from lunar cold traps presents another set of difficulties).

- Hexagonal cross-section of habitat is not ideal for efficient pressure containment and would incur a weight penalty.

Comments by Miriam Dall‘Igna

+ Great and sustainable idea.

+ Clear diagrams help to understand the concept. Open questions: If the solar panels adjust to capture the best sun angles, how could the design enable that? How does the habitat connect to the chassis? It would be interesting to explore some design ideas.
