Experimental setup

The existing knowledge about Mars is a valuable basis for planning the first settlement, but during the development of the Marspedia project some open issues arise, that require an Experimental Setup. This page collects descriptions of those experiments required to find the needed knowledge.

greenhouse heating

The amount of energy to heat a Martian greenhouse, that is lit by direct or indirect sunlight, is unknown. It depends on the temperature difference between the Martian atmosphere and the temperature inside the greenhouse. It depends even more on the shape and the insulation methods and materials. An example layering of insulation must be developed. Influences of different greenhouse sizes must be taken into account.

assumptions

The temperature inside the greenhouse is constantly at 20°C.
The known values of the environmental conditions are used for the experiment.
No heating effect from the sunlight.

goals of the experiment

A viable shape of the greenhouse, capable to hold the air pressure.
A viable layering of insulation.
The required amount of energy per m².

soil production

Soil can be made from powdered regolith, enriched with artificial fertilizer and moistured with water. A small amount of terrestrial soil implants microbes. Seeds of pioneer plants are used to start greening. It is unclear, how long it takes to make mold this way, allowing to grow food plants.

assumptions

The temperature is constantly at 20°C.
The air pressure is terrestrial sea level.

goals of the experiment

The best amount of moisture.
The best pioneer plants.
The time until the soil is usable for food production.

wind turbine

The low atmospheric pressure on Mars has an effect on the work of a wind turbine. This can be simulated on Earth in a low pressure wind tunnel. The best shape of the rotor wings for thin air is needed. The stability for heavy dust storms must be considered. Additionaly we need an exploration on the Martian surface to find out about the strength and frequency of winds.
