London, Oct 23: A study has found Mars to attain near ideal conditions for dynamically creating oxygen from atmospheric carbon dioxide with the use of plasma technology.

As stated by researchers from the University of Porto in Portugal and Ecole Polytechnique in Paris, Mars is already comprised of 96 per cent CO2 (carbon dioxide) in its atmosphere.

The PTI reported the research published in the journal Plasma Sources Science and Technology depicting the pressure and temperature ranges in the Martian atmosphere that sustains non-thermal plasma useful for effective production of oxygen.

Vaso Guerra, a researcher from the University of Lisbon in Portugal put forth his statement about their next significant steps of sending a manned mission to Mars for exploration of space. They are planning to create a substantial change by creating a breathable environment on Mars.

Plasma reforming of CO2 on Earth is an advancing research study, stimulated by the problems of change in climate and production of solar fuels. Plasmas at low temperature are one of the best media for CO2 deformation, where the molecule splits into oxygen and carbon monoxide combined with direct electron impact, and transfer of electron into vibrational energy.

Mars has superficial conditions for In-Situ Resource Utilisation (ISRU) through the plasma.

The cold atmosphere may stimulate high vibrational effect for producing oxygen than that achievable on Earth. The low atmospheric temperature on Mars will also enable the reaction to be slowly giving the maximum amount of time for separation of molecules.

The plasma technology decomposition method aims to offer a two output for a manned mission towards Mars. The technique would provide a stable supply of oxygen and as a source of fuel that can be used as a propellant mixture in rocket vehicles. This approach by ISRU could help in simplifying the logistics involved in space exploration by increasing self-sufficiency, decrease the risks to the crew, and reduction in expenditure for carrying out the mission.

Research Reveals, Red Planet’s Rivers Were Wider Than Those On Earth Today

If the dates for these massive rivers are correct, the findings could suggest that Mars' late-stage atmosphere disappeared faster than previously calculated, or that there were other drivers of precipitation under low-atmosphere conditions, the researchers noted.

Mars’ rivers flowed intensely and may have persisted as recently as one billion years ago, reveals a survey that found that the red planet’s rivers were wider than those on Earth today.

The study by scientists at the University of Chicago catalogued these rivers and found that significant river runoff persisted on Mars later into its history than previously thought.

According to the study, published in the Science Advances journal, the runoff was intense and occurred at hundreds of locations on the red planet.

These findings suggest that climate-driven precipitation may have taken place on Mars even during the time that researchers think the planet was losing its atmosphere and was drying out.

This complicates the picture for scientists trying to model the ancient Martian climate, said lead author Edwin Kite, Assistant Professor at the University of Chicago.

“It’s already hard to explain rivers or lakes based on the information we have. This makes a difficult problem even more difficult,” he said.

But, Kite said, the constraints could be useful in winnowing the many theories that researchers have proposed to explain the climate.

The survey used image data of well-preserved paleo-river channels, alluvial fans and deltas across Mars, and calculated the intensity of river runoff using multiple methods, including an analysis of the size of the river channels.

In the river basins, for which there is most data, Mars’ rivers were about two times wider than those on Earth.

Between 1 and 3.6 billion years ago, and likely after 1 billion years ago, there was intense runoff in these channels, amounting to 3 to 20 kg per square metre each day.

The runoff appeared to have been distributed globally, and was not a short-lived or localised phenomenon, the researchers said.

If the dates for these massive rivers are correct, the findings could suggest that Mars’ late-stage atmosphere disappeared faster than previously calculated, or that there were other drivers of precipitation under low-atmosphere conditions, the researchers noted. (IANS)
