  NASASpaceflight reports scientists, using data from the joint European and Russian ExoMars Trace Gas Orbiter at Mars, found potential evidence of volcanic activity — volcanic gases released by fissures in the Martian surface, a process also observed in volcanic regions on Earth (nasaspaceflight.com/2026). Debut storyline — atmospheric evidence of possible Martian volcanism. Watch: whether the gas signatures are confirmed as volcanic, follow-up observations, and independent analyses.
