Windtunnel Facilities

The Department of Geociences has two open-circuit wind tunnels, which today are part of the Aarhus University wind tunnel laboratory. These are used for sand transport studies. The Mars laboratory has also access to two closed-circuit wind tunnels placed in vacuum chambers. These can be operated under low pressure and are used for Mars surface simulation experiments.

These wind tunnels were complemented by a bio-chamber constructed for long-term microbiological experiments under Martian atmospheric and UV conditions, and two smaller environmental chambers for chemical and physical surface reaction studies.

Besides being an instrument for basic research purposes, the wind tunnels are also used in instrument development, for calibrations and in tests of solar panels and other items that are constructed for functioning in the dusty, cold and dry environment on Mars.

Mars Exploration Rover (NASA)

The Mars Simulation Laboratory has been working in close collaboration with the Niels Bohr Institute, University of Copenhagen. The NBI was responsible for the magnetic properties experiments on NASA’s, Mars Pathfinder in 1997, and for magnetic properties experiments on the two NASA, Mars Exploration Rovers that landed on Mars in January 2004. Magnetic dust capture experiments and experiments with Mössbauer spectroscopy and x-ray fluorescence was part of the NBI wind tunnel experiments.
