Introduction

The Mars Simulation Laboratory is an interdisciplinary research collaboration of biologists, chemists, geologists and physicists who work together on joint research related to the planet Mars. The group has built its own research facilities and has access to all necessary facilities under the Faculty of Science and Technology. Furthermore, some group members have developed instruments for Mars missions.

Mars (Hubble telescope)

The main focus of the Mars Simulation Laboratory is the study of processes closely related to the surface of Mars.
This can be done from Earth or satellites in Earth orbit or, more detailed, from Martian satellites as imaging or spectroscopic data. However, the most detailed data are collected by Martian landers and rovers on the surface. And though we have not yet samples returned by Mars missions, we have today, out of the about 60.000 meteorites found on Earth, 124 that are identifyed as meteorites coming from Mars. Apart from utilizing satellite data and data from landers, rovers and meteorites, the Mars Simulation Laboratory studies Mars processes by means of analogue samples (soil, dust, pure minerals and microbiology). The equipment used are wind tunnels, tumbling carousels that mimics saltation processes and a chamber for microbiological experiments under Martian conditions.

Dust in Mars' atmosphere (NASA)

The background for the study of Mars can be expressed in four scientific goals shared by ESA and NASA and valid also for the Danish collaboration group:

Goal 1: Determine whether life ever arose on Mars
Goal 2: Characterize the climate of Mars
Goal 3: Characterize the geology of Mars
Goal 4: Prepare for human exploration

Mars Laboratory and Windtunnel AWTS II
Mars Express (ESA)

The Mars Laboratory has been recognized as one of ESA's Mars Express Collaboration Laboratories. We have developed instruments proposed for participation in ESA’s ExoMars mission under the ESA, GSTP programme. The instrument “Teltale”, a wind sensor, was developed by Marsgroup members and mounted on top of the climate mast on the NASA Phoenix lander. It  collected a detailed set of wind data interpreted by the Mars laboratory group.

The research can be categorized in four groups as listed below:

  • Survival, activity and diversity of microbial communities under Martian conditions
  • Heterogeneous processes in the Martian atmosphere. Reactive molecules and oxidation processes at the surface.
  • Aerodynamic modelling and magnetic dust particle capture. Particle adhesion, cohesion and charging. Particle velocity and particle size determination methods, and wind measurements and interpretation under low pressure conditions.
  • Mars-analogue mineralogy. Mineralogical experiments under Martian condition. Mars meteorite studies. Transmission, backscatter and CEMS Mössbauer spectroscopy.
