The surface pressure is just over 100 times weaker than ours at sea level, meaning that a human standing on the surface would see their blood instantly boil. The red colour on Mars’s surface is the result of rusting, due to iron present in the rocks and soil reacting with oxygen to produce an iron oxide.
