7. Being farther from the Sun than the Earth, the temperatures on Mars are lower; they fall between -153 degrees, at the poles, and 20 degrees at the equator;

8. Because it has an axial inclination very close to that of the Earth (25.19 Mars, 26.27 Earth), Mars has seasons, just like our planet;

9. The Martian atmosphere is very thin and is formed largely of carbon dioxide (96%);

10. On Mars is the highest mountain in the Solar System, Olympus Mons, with an altitude of 26,000 m and a surface similar to that of Germany;

13. Two years ago, on November 26, 2011, NASA launched Mars the most expensive and complex rover in history, Curiosity, part of the mission "Mars Science Laboratory"; MSL landed on the Martian surface after 9 months on August 16, 2012;

14. Based on the evidence gathered since the beginning of the mission, in September 2013, the Curiosity rover discovered that Mars was drinking water;

15. Mars Phobos satellite is getting closer and closer to Mars; scientists believe that in the future it will collapse on the surface of the planet;
