Plasma conversion of CO2 from the Martian atmosphere
Scientific Dissemination
Highlight in Europhysics NewsMaking oxygen on Mars thanks to plasma technology "Sending a manned mission to Mars is one of the next major steps in space exploration. Creating a breathable environment, however, is a substantial
challenge. Plasma technology could hold the key to creating a sustainable oxygen supply on the red planet, by converting carbon dioxide directly
from the Martian atmosphere."

Highlights of 2017 from PSSTThe case for in situ resource utilisation for oxygen production on Mars by non-equilibrium plasmas "Herein, it is argued that Mars has nearly ideal conditions for CO2 decomposition by non-equilibrium plasmas. It is
shown that the pressure and temperature ranges in the $\sim 96 \% $ CO2 Martian atmosphere favour the vibrational
excitation and subsequent up-pumping of the asymmetric stretching mode, which is believed to be a key factor for an
efficient plasma dissociation, at the expense of the excitation of the other modes. Therefore, gas discharges operating
at atmospheric pressure on Mars are extremely strong candidates to produce O2 efficiently from the locally available resources."

Article in TESLAratiNew plasma technology could help SpaceX colonize Mars "Elon Musk’s vision of establishing a human settlement on Mars just became a lot more feasible, after a study conducted by a team of
Portuguese-French scientists concluded that plasma technology could help foster the production of oxygen on the Red Planet’s atmosphere."

Article in NewsweekLiving on Mars: Settlers could create oxygen from carbon dioxide with Cold Plasma "Lead author Vasco Guerra, a physicist at the University of Lisbon in Portugal, had been using plasma to break down carbon dioxide here on Earth,
a goal many research teams are looking to tackle to address challenges in climate change and clean energy."

Article in New ScientistHow we could make oxygen on Mars, plus fuel to get home "The atmosphere on Mars is 96 per cent carbon dioxide, says Vasco Guerra at the University of Lisbon in Portugal. This can be split to extract breathable
oxygen and carbon monoxide, a fuel that could give us a “gas station on the Red Planet”, he says. He and his team calculate that creating a carbon dioxide
plasma — a mush of ions made by passing an electric current through a gas — could split carbon dioxide from oxygen more easily on Mars than on Earth."

Article in Futura SciencesMars : on a trouvé comment y produire de l'oxygène "Pour les missions humaines sur Mars, envisagées dans le courant de la décennie 2030, l'approvisionnement en oxygène a toujours été imaginé comme venant d'une extraction à partir de l'environnement martien. Mais l'idée reste théorique. Une équipe des universités de Lisbonne et de Porto, ainsi que de l'École Polytechnique (Paris) a peut-être trouvé une piste prometteuse. Olivier Guaitella, chercheur au Laboratoire de physique des plasmas et co-auteur de l'étude, nous explique tout."

Article in Spaceflight InsiderPlasma technology could help produce sustainable oxygen supply for human colonies on Mars "A future human colony on Mars will need a sustainable oxygen supply for its operations in the harsh Martian environment. A new research
conducted by a team of Portuguese-French scientists suggests that plasma technology could be the key to producing the necessary amount of
oxygen for crew activities on the Red Planet."

Article in AstronautOxygen from Plasma could help astronauts breathe on Mars "The researchers, who published an article about their work in the journal Plasma Sources Science and Technology, say that we
could create oxygen from the cold atmosphere of Mars, which is 96 percent composed of carbon dioxide, through a process called
decomposition. This process breaks up the carbon dioxide molecule into oxygen and carbon monoxide."

Article in The EngineerMars explorers could breathe oxygen made by plasma "Existing cold-plasma technology could convert Martian CO2 atmosphere into breathable oxygen for astronauts, says Portuguese study.
Researchers from Lisbon and Porto Universities believe that future crewed missions to Mars could make their own oxygen for exploring
the surface from the local atmosphere. “Sending a manned mission to Mars is one of the next major steps in our exploration of space.
Creating a breathable environment, however, is a substantial challenge,” said the lead author of the study in the journal Plasma Sources
Science and Technology, Vasco Guerra."

Article in IFL ScienceAstronauts Might End Up Making Their Own Oxygen On Mars "When it comes to space travel, there’s a simple rule. If you didn’t bring it with you, you need to make it there. This usually refers to
building material but it might soon apply to oxygen too.
In a study published in Plasma Sources Science and Technology, Portuguese and French researchers showed that both the temperature
and pressure of the Martian atmosphere are good enough to efficiently produce oxygen. Astronauts would use nonthermal plasma to break
down carbon dioxide, which makes up most of the Red Planet's atmosphere."

o método consistirá em aplicar "campos elétricos" ao ar de Marte, que é 96 por cento dióxido de carbono, e dividi-lo em monóxido de carbono
e oxigénio, conseguindo criar ar respirável em ambientes fechados."
