Laboratory simulation of Martian atmospheric chemistry
نویسنده
چکیده
Measurements of the yield of important trace gas species such as ozone, evolved during photolytic reactions have been made under Martian environmental conditions in one of the The Open University’s Mars simulation chambers. The simulation chamber can mimic Martian temperatures and pressures and a UV solar simulator can be added to irradiate a Marslike gas mixture within the chamber to drive chemical reactions. The concentration of trace gases is measured in situ using a Fourier Transform Infrared spectrometer (FTIR). The data obtained will be invaluable in improving the qualitative and quantitative representation of chemical species calculated using Mars global circulation models (MGCMs) and in interpreting a new suite of observational data such as from ExoMars Trace Gas Orbiter (TGO).

An Investigation of Martian Atmospheric Trace Species Using Laboratory and Computer-based Simulation
Introduction: The study of trace gas species in the Martian atmosphere has the potential to shed new light on wide-ranging topics such as the search for life and the history of liquid water on the planet. Investigating the way that molecules such as ozone, water and HCl are cycled in the atmosphere will give insights into the interactions taking place between the atmosphere, lithosphere and any...

متن کاملCharacterization of Simulated Martian Atmospheric Entry Plasma
During entry into the Martian atmosphere the friction between the surface of a probe and the atmosphere will cause thermal ionization of the surrounding air. The plasma parameters associated with this Martian atmospheric entry plasma will vary considerably depending on the spacecraft’s trajectory. The probable range of these parameters was evaluated using the existing Martian atmospheric data a...
متن کاملElectrification of wind-blown sand on Mars and its implications for atmospheric chemistry
[1] Wind-blown sand, or ‘saltation,’ creates sand dunes, erodes geological features, and could be a significant source of dust aerosols on Mars. Moreover, the electrification of sand and dust in saltation, dust storms, and dust devils could produce electric discharges and affect atmospheric chemistry. We present the first calculations of electric fields in martian saltation, using a numerical m...
