The actual horizon on Mars would be unreliable so one would have to use an artificial horizon. But... how could you have liquids in a partial vacuum and sub-freezing temperatures? A tiny heater built into the sextant? I thought I heard about some type of aeronautical sextant that used a column with paper at the bottom. Pressing a trigger dropped an inked ball bearing down the collumn to strike a mark on the paper. Does that sound familiar?
