The surfaceof Mars is therefore much colder than the Earth would be at that distance from the Sun. Mars has a very thin atmosphere composed mostly of the tiny amount of remaining carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and traces of oxygen (0.15%) and water (0.03%...
They want to learn more about the Martianatmosphere, which is composed mostly of carbon dioxide but could also include trace amounts of other gases that may have been around since the planet’s formation. This image shows a rock core about the size of a piece of chalk in a sample ...
