| Abstract: | The Martian Environment Simulator (SAM “Simulatore di Ambiente Marziano”) is a interdisciplinary project of Astrobiology done at University of Padua. The research is aimed to the study of the survival
of the microorganisms exposed to the “extreme” planetary environment. The facility has been designed in order to simulate
Mars’ environmental conditions in terms of atmospheric pressure, temperature cycles and UV radiation dose. The bacterial cells,
contained into dedicated capsules, will be exposed to thermal cycles simulating diurnal and seasonal Martian cycles. The metabolism
of the different biological samples will be analysed at different phases of the experiment, to study their survival and eventual
activity of protein synthesis (mortality, mutations and capability of DNA reparing). We describe the experimental facility
and provide the perspectives of the biological experiments we will perform in order to provide hints on the possibility of
life on Mars either autochthonous or imported from Earth.
Presented at: National Workshop on Astrobiology: Search for Life in the Solar System, Capri, Italy, 26 to 28 October, 2005. |
