I can’t imagine this actually being useful information

Pretty cool. If I’m understanding the article correctly there are a few potential benefits.
First searching for biosignatures of life elsewhere.
Second as one potential candidate for geo-engineering. The layer they talk about changes the environment to an extent helping other organisms to live easier, along with itself. One piece of the puzzle to potential terraforming, even if it’s within a biosphere like structure that uses natural martian soil.
We’re along way for any kind of terraforming imo but still, a step.
