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.
  • 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.

wind turbine

Part 1 on Earth

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.

Part 2 on Mars

An experimental setup on Mars is required to clarify the viability of wind turbines due to the strength and frequency of winds. Small turbines with a diameter of a few centimeters should be brought to the Martian surface, each in a different region.

goals of the experiment

  • best shape of the rotor wings
  • peak wind speed
  • average wind speed in a Martian year
  • global wind pattern
