Non Thermal Plasma could be used to produce oxygen on Mars

Toutes les versions de cet article : [English] [français]

Mars en vraies couleurs The production of oxygen from available resources on the surface of Mars is one of the main challenges to be solved, whether for manned missions or simply to be able to take off from the planet’s surface and bring back samples to Earth. A study carried out in collaboration between the team of Professor Vasco Guerra of the Instituto Superior Tecnico (IST) in Lisbon and Olivier Guaitella of the LPP, recently showed that cold plasmas technologies have many advantages for efficient oxygen production from the Martian atmosphere. An article published in PSST details in particular the beneficial effect of very low Martian atmospheric temperatures on the vibration excitation of CO2 in a cold plasma. The energy efficiency achieved for CO2 decoupling and conversion to O2 could then be higher than that achieved by solid electrolysis in NASA’s current project (MOXIE). The PSST article was downloaded more than 2000 times in less than 15 days after its publication, and was relayed in many international media (see in particular http://www.futura-sciences.com/sciences/actualites/exploration-martienne-mars-on-trouve-y-produire-oxygene-68988/ ).
