Mars may not be geologically dead after all. 🔴

Our ExoMars Trace Gas Orbiter has detected hydrogen chloride above volcanic fissures in the Alba Mons region, which scientists suggest could be linked to dormant volcanic activity beneath the surface.

There is hot news coming from Mars.

For the first time, orbital data is revealing signs of young volcanism. Mars might not be geologically dead, just sleeping.

Pitted dunes in the southern highlands of Mars, seen by Mars Reconnaissance Orbiter in September. The area shown is about a kilometer wide.

"The Trace Gas Orbiter was able to find the smoking gun."
Orbiter Detects Signs of Activity on Mars
Researchers suggest gas is being released from hot magma deep beneath Mars' surface after discovering intriguing new fissures.

New evidence from ESA's ExoMars Trace Gas Orbiter (TGO) indicates Mars is not quite the geologically dead planet that many think it is.
L'orbiteur ExoMars Trace Gas Orbiter (TGO) de l'Agence Spatiale Européenne a détecté des signes de volcanisme latent et des émanations de chlorure d'hydrogène au-dessus des flancs du volcan martien Alba Mons.

Mars n'est pas géologiquement morte en profondeur.

This Mars Reconnaissance Orbiter HiRISE camera observation is labeled "Possible Pit in USGS Cave Candidate Catalog Entry Number CC0145" and was captured on Sept. 2 of this year.

TGO’s high-resolution colour camera takes detailed images of the surface, revealing composition and topography.

It even captured NASA's Perseverance rover in Jezero crater. Can you spot it? 🤖

I like @davidmbarnett.bsky.social's suggestion but maybe we should save it for a solar orbiter.

Recent fractures on the surface of Mars and gases detected by an orbiter probe provide some of the strongest evidence yet that the planet is volcanically active

Europe’s TGO orbiter picked up something odd in the Martian atmosphere: spikes of hydrogen chloride right over the fissures on Alba Mons.

Not in winter, when that gas usually shows up, but at the start of northern summer.

It doesn’t match the normal seasonal pattern.

actually im quite low on the orbiter rankings but it is also hard to rival erin

Orbiter and rover data are showing that water may have flowed more recently on the Martian surface, maybe even into the present era.
