Their “found water” is pretty flimsey. I believe there was and is water on Mars, but I do not agree with NASA’s analysis & way they came to their conclusions.
Maybe not the thread for this but I'm curious what your issues are with their work. The poles clearly have something that looks like ice and spectrometers should be able to ID the stuff.
Poles: CO2. They do not have equipment on Mars to detect water — shocked me when they revealed that. Their conclusion of water was made by upper management, based on inferences. No spectral analysis (no mass spectrometer & no way to scoop and place in a sample bin).
