Der Mars verfügt möglicherweise über riesige Magmasysteme unter seiner Oberfläche

This article touches on how Mars research contributes to our search for habitable exoplanets.

So cool learning new things about our planets. Growing up it seemed like we had it all solved but learning and growing with the universe we were born from is so fun! Like the opposite of a murder mystery.

> But whether plate tectonics is necessary for life is not clear.

It’s not. Availability of volatiles and organic molecules that can do amino (or amino like) chemistry, eruptions are the easiest way to get that (reduced compounds, mineral catalysts etc) but don’t have to be volcanic.

They can also just exist everywhere like on Titan where the atmosphere has the compounds the pools of sludge on earth, that eventually made humans, had.

Radiation environment is likely a big big requirement so magnetosphere or parent magnetosphere. It’s possible the chemistry can still happen but biology likely won’t work, radiation tolerance is an evolved trait not inherent so life has to start without high energy particles screwing it up.

Liquid water is possibly essential too but it’s postulated that other solvents could work (liquid ammonia commonly cited) but life would be very slow in low energy cold.

Plate tectonics & volcanism make places that might otherwise not have the right chemistry have it for amino chemistry but certainly isn’t a prerequisite for life to exist at all.
