Mysterious gas leaks suggest Mars may still be volcanically alive

Mysterious gas emissions and fresh volcanic fissures suggest that Mars may not be geologically dead after all, with hot magma potentially still active deep underground. The discovery could point to hidden pockets of warmth and chemical energy capable of supporting microbial life beneath the Red Planet’s surface.

The established view that the Red Planet is geologically completely inert is being challenged by new chemical signals rising from beneath the surface. Latest measurements obtained from the ExoMars Trace Gas Orbiter (TGO) satellite within the European Space Agency revealed that magmatic heat and mobility may still exist in the depths of Mars' giant volcanic structures. Scientists state that mysterious gases leaking from cracks in the planet's crust may be evidence of hidden volcanism.

Trace of Hydrogen Chloride in Alba Mons Cracks

Researchers detected unexpected concentrations of hydrogen chloride gas in the fault lines above the large volcanic region called Alba Mons. The international study, led by Alexander Trokhimovskiy and published in Science Advances, argues that these chemical leaks may originate from hot magma masses underground. The TGO satellite recorded the gas in question for the first time in the Martian atmosphere in 2021. Hydrogen chloride, which similarly mixes with the atmosphere from volcanic vents on Earth, strengthens the possibility that similar thermal processes are operating in the depths of Mars. Prof., an expert at the Space Research Center of the Polish Academy of Sciences. Daniel Mège states that the planet does not lose its internal heat and maintains enough temperature to fuel volcanic activity.

Direct Reflections on Mars Exploration Missions

The resulting data has the potential to directly influence the priorities of future space exploration targeting the Red Planet. The presence of active magmatic systems deep within the planet brings to the agenda the possibility of the existence of sheltered environments that can host both underground geothermal energy and liquid water. This will play a critical role in determining landing coordinates in subsequent surface missions and long-term human exploration projects planned by institutions such as NASA and the European Space Agency. This evidence, which changes the perception of a frozen and completely extinct celestial body, prompts the scientific world to update planetary models.
