What are Some Major Landmarks on Mars?
Mars is a desert planet covered in iron oxide (rust), which gives it its red color and nickname, “the Red Planet”. The planet has a tenuous atmosphere of mostly carbon dioxide, just 0.6% as thick as the Earth’s. The atmosphere on Mars has a pressure similar on Earth at an altitude of 35 km (22 mi). The surface temperature ranges from −140 °C (-220 °F) during the winter to highs of up to 20 °C (68 °F) in summer. Like all planets without bodies of water to modulate their temperature, Mars experiences greater thermal extremes than Earth. Although there is evidence that liquid water has flowed on Mars’ surface in small amounts in the last few years, it is probably a rare occurrence, as most H2 sublimates (goes directly from solid to gas) rather than passing through a liquid stage. Some hardy microbes from Earth would be capable of surviving in the Martian environment, and may have already been introduced by the Mars rovers that have been sent there in the last few decades.
