While increased methane levels measured by are exciting, as possible indicators for life, it’s important to remember this is an early science result. To maintain scientific integrity, the team will continue to analyze the data before confirming results.

We don’t yet know where methane on Mars comes from. A leading idea is that methane on Mars is being released from underground reservoirs created by past biology. But sometimes, methane is a sign of geology rather than biology. Learn more:

This is so interesting. I just perused the NASA article and I'm kind of stumped -- they pin geological factors for methane release, but there haven't been active volcanic regions on Mars for millions of years. Why the 10x increase in Aresstrical detection in specific areas?

Gah -- blame autocorrect; I meant "Arestrial" after Ares.

It sounds to me that if there were Arrestrical volcanism involved in the emission and detection of methane in-situ, would there not have had to be recent volcanic activity to release the chemical whiffs for the on-Mars scintillator to pick up, or am I missing something?

Unless the microbes are underground, I'm thinking it's geological. Too much radiation on the surface for any form of life.

But seasonal implies current biological processes at work. Period of activity/hibernation.
