Top similarities and differences between Mars and Earth.
Mars is only about one-half the diameter of Earth, but both planets have roughly the same amount of dry land surface area. This is because over two-thirds of the Earth's surface is covered by oceans, whereas the present surface of Mars has no liquid water. Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are.
Similar to planet Venus, carbon dioxide dominates Mars.Lucky for us, CO 2 is less than 1% of Earth’s atmosphere composition. Because Mars atmosphere is 96% carbon dioxide, any plants would blossom if they existed. All they are missing is a source of water. While 78.1% of Earth’s atmosphere is nitrogen, Mars is only 1.9% nitrogen-based.Earth is rich in oxygen (20.9%).
The discovery of these microscopic life forms on a rock that came from mars found in an Antarctic ice field in 1984 is amazing because we are now almost sure that life is or was possible on other planets than earth. Still, I wish that we would have found remains of an ancient civilization instead of tiny carbonized microbes. Even though, it is a step in the right direction. I once saw pictures.

Following this rule, when Earth is discussed as a specific planet or celestial body, it is capitalized: It takes six to eight months to travel from Earth to Mars. When Earth is a proper noun, the is usually omitted. When you are talking about the ground or soil as a surface or stratum, then you must lowercase the word: The archaeologists.
Haqq-Misra is a researcher at the Blue Marble Space Institute of Science, and he recently published an essay titled “The Transformative Value of Liberating Mars” in which he argues Mars should.
The atmosphere of Mars is the layer of gases surrounding Mars.It is primarily composed of carbon dioxide (95.32%), molecular nitrogen (2.6%) and argon (1.9%). It also contains trace levels of water vapor, oxygen, carbon monoxide, hydrogen and other noble gases. The atmosphere of Mars is much thinner than Earth's.The surface pressure is only about 610 pascals (0.088 psi) which is less than 1%.
