Study reports Mars releasing hydrogen chloride, suggesting possible volcanic activity

The short version

• Slashdot reports an international team's Science Advances paper analyzes 2021 ExoMars orbiter data showing Mars releasing hydrogen chloride gas.[Slashdot]
• Researchers suggest the gas may escape from hot magma deep beneath the surface, citing new fissures thousands of feet long along a massive volcano.[Slashdot]
• The magma link remains a suggestion, and colead author Daniel Mège argues the fissures could help locate evidence of past life.[Slashdot]

Key facts

• An international team published a Science Advances paper analyzing 2021 data from the European and Russian ExoMars Trace Gas Orbiter.[Slashdot]
• The study reports that Mars is slowly releasing hydrogen chloride gas.[Slashdot]
• The team reported new fissures measuring thousands of feet in length along a massive volcano.[Slashdot]
• Researchers concluded that discolorations along the fissures may be mineral deposits left by seeping gases, similar to volcanic vents on Earth.[Slashdot]
• Study colead author Daniel Mège, a Polish Academy of Sciences professor, argued the fissures could be a good place to find evidence of past life.[Slashdot]
