    I’ve seen blue sunset pictures from Mars before, but I suspect someone pumped up the saturation on this picture.

        Thanks that was interesting. Does mars wobble on it’s axis? I know they have a summer and winter so they must I guess. In the winter they get what looks like ice build up around the pole not getting sun, but it’s dry ice, co2, super cold -276 or something like that.

          There’s a semi-permanent ice cap that’s mostly water, but in the winters about a quarter of the atmosphere condenses down into dry ice. The axial tilt is very similar to Earth, but the seasons last significantly longer, and the orbit around the Sun is more elliptical.

        Pretty sure there aren’t any golf courses on Mars yet. Such a waste they are short enough of water.

            Pfas that’s why. Astroturf is lousy with pfas. Mars is slippery enough as is without adding more deathslip substance.
