ExoMars Orbiter Detects Hydrogen Chloride on Mars, Flagging 2021 Fissures Near Alba Mons

Summary
Science Advances research tied 2021 ExoMars Trace Gas Orbiter data to hydrogen chloride spikes around Alba Mons, challenging the view that Mars is geologically dead.
New fissures thousands of feet long on the volcano’s flanks, plus discoloration resembling Earth volcanic vents, point to gas seeping from hot magma beneath the surface.
Researchers said the findings suggest Mars retained enough internal heat for volcanic activity until recently and possibly still does, helping explain earlier puzzling seasonal and out-of-place chlorine spikes.
That activity could reshape views of ancient Mars by implying a warmer, thicker atmosphere and more liquid water, while the fissures themselves may be prime targets in the search for past microbial life.
