Three styles of EVA suit, as you'd expect. My guess is that the NASA ones have the Quasimodo backpacks, the Russians are in blue. There are massive pressurised rovers with a strong Ron Cobb vibe. Character in a blue suit standing by the lander, but 'HAB' makes more sense if the letters are Latin and not Cyrillic. Maybe the missions are cooperating - maybe not initially, but they find it necessary as the story develops. Plus an odd, box-like lander. Probably unmanned supply since there are no windows, though there is a docking port.
