    Some pretty interesting ideas. I was unaware that anything was living in the Atacama salt deposits, which certainly lends some credence to the idea that something could be pulling moisture out of the air on Mars, thin as it is.

      I remember reading some article about deserts, and how, even when they seem completely empty of life, they actually have entire tiny fragile ecosystems living just under the sand. The article was in favor of imposing restrictions on dune buggies in a couple deserts where the activity was growing out of hand, because wherever the buggies went, that fragile ecosystem was just wiped out. And with the harsh conditions, it takes a really long time for them to recover.

        Yeah, cryptobiotic crust! I’ve seen it in the Sonoran desert. It doesn’t look like much, I think if I hadn’t been warned ahead of time not to step on it I might have just done it without thinking. Given that just footprints can take on the order of decades to heal I think a dune buggy ban makes sense in areas where it grows.

        I’m still surprised to learn about the microbes in the Atacama: it’s the driest place on earth, and I would have expected the salt deposits to make it even harder for anything to live there. Yknow what they say I guess: “Life, uh, finds a way.”

          Yeah, that’s it! I couldn’t remember the details, and cba to search for them. Thanks!
