@65dBnoise I'd also crack at that kind of temp differences... 😀

Speaking of thermal stresses, a TV recommendation for anyone in the audience grokking Swedish: a comedian-gone-traveller series (think Michael Palin, Richard Ayoade...) on , visiting most extreme weather places on Earth. attempting a 5km run on Death Valley was really something 😀

@sharponlooker
Jezero daily temperature differences appear to be less than 100°C. Are such differences enough to fracture seemingly hard solid rocks in a dry environment? Probably not, but we still don't know the composition of those rocks and their physical properties. Maybe there are other parameters that need to be considered for their fracturing, besides generic 'thermal stress', which means that a story/theory needs to be developed to explain what happened and what we see today.
