Abstract

It has been recently advocated that Mars has excellent conditions for oxygen and fuel production directly from atmospheric CO 2 using non-equilibrium plasmas. The Martian conditions would be favorable for vibrational excitation and/or enhanced dissociation by electron impact, two important pathways for CO 2 plasma dissociation. Herein we confirm these theoretical predictions by measuring, for the first time, the vibrational temperatures of CO 2 and the CO and CO 2 concentrations in realistic Martian conditions. In situ Fourier transform infrared spectroscopy measurements are performed in experiments conducted in DC glow discharges operating at pressures p = 1–5 Torr, discharge currents I = 10–50 mA, initial gas temperatures of 220 K and 300 K, both in pure CO 2 and in the synthetic Martian atmosphere 96% CO 2 –2% Ar–2% N 2 . To analyze and interpret the experimental results, we develop a detailed self-consistent kinetic model for pure CO 2 plasmas, describing the coupled electron and heavy-particle kinetics. The simulation results are in very good agreement with the experimental data. It is shown that the low-temperature conditions may enhance the degree of vibrational non-equilibrium and that the Martian atmospheric composition has a positive effect on CO 2 decomposition. Accordingly, the present investigation confirms the potential of plasma technologies for in situ resource utilization on Mars.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
