Abstract:
Electrostatic coagulation properties of dust above planetary surfaces (CRISWELL, 1972, RHEE ET AL., 1977, REID, 1997, HORÁNYI ET AL., 1998, SICKAFOOSE ET AL., 2001) were studied by FOELDIX instrument of Hunveyor. We developed FOELDIX by a detector unit in order to observe biomarkers on Mars by collecting dust thrown out from dusty regions. The dust collector experiment (FÖLDI ET AL., 1999), with the observation capability of the size dependent dust particles (FÖLDI ET AL., 2002), was developed by fitting a nutrient container detector pattern which can show various types of bacteria in the inner detector-wall of the modified FOELDIX instrument (FÖLDI ET AL., 2001). Coagulation of electrostatically charged dust particles, rare H2O molecules and suggested extremophile bacteria from the dusty Martian surface is carried out by our experimental assemblage through the space with electrodes. Coagulated grains are allowed to precipitate in the vicinity of some specially charged electrodes (FÖLDI, BÉRCZI, 2001a). If living units form a community, a consortia of bacteria and fungal spores with the attached soil then the cryptobiotic crust (PÓCS, 2002) components of Mars may also be found and distinguished by this measuring technology.
