Sharp. Edited March 21, 2023 by JoeSchmuckatelli Quote Link to comment Share on other sites More sharing options...
JoeSchmuckatelli Posted February 12, 2023 Author Share Posted February 12, 2023 Been thinking about this one. The ripples in mud turned to stone. Typically this happens when sedimentary deposits are covered over by other layers and given enough pressure and time become stone. But I'm wondering if you simply let the mud dry, and then given enough time and radiation and a lack of disturbance that the soft material can become stone without having to be buried. This could work if Mars' thin atmosphere works to allow the surface water to boil off, but subsurface aquifers still exist - and then after a meteor strike the aquifers leak onto the surface creating short lived lakes - and possibly even seas. Given this scenario, it's unlikely surface life (beyond simple microbes) ever existed on Mars. Quote Link to comment Share on other sites More sharing options...

Well, I don’t see the need for a new one unless we just tack any updates here. Edited February 13, 2023 by Gargamel Quote Link to comment Share on other sites More sharing options...

tater Posted March 21, 2023 Share Posted March 21, 2023 @JoeSchmuckatelli maybe you should rename this as the generic Curiosity thread? Quote Link to comment Share on other sites More sharing options...
