Trace Gas Orbiter data suggest possible volcanic activity on Mars
From the Space digest for Nov 4, 2026
Thread: space — Trace Gas Orbiter Mars volcanism · new
What happened: Scientists, using atmospheric observations from the joint European and Russian ExoMars Trace Gas Orbiter at Mars, have found potential evidence of volcanic activity: volcanic gases released by fissures in the Martian surface, a process also seen in volcanic regions on Earth (NASASpaceflight).
What's genuinely new: A named atmospheric finding pointing to possible volcanic outgassing through fissures in the Martian surface, from an orbiter circling the planet.
Watch: whether the gas signatures hold up as volcanic activity, and any follow-up observations or independent analyses.
