MARS
Mars surface morphological features of both the Earth and the Moon: craters, lava fields, volcanoes, dry riverbeds and sand dunes. But the overall look of the Martian landscape differs from that presented our satellite as a result of the existence of a tenuous atmosphere on Mars.
WATER ON MARS:
There is a real water cycle on Mars different from Earth. Due to the normal environmental conditions of Mars, atmospheric pressure and temperatures below the Earth, Mars water sublimates, passes directly from solid to gas and vice versa without going through the liquid. On Mars, water sublimates the ground at a temperature of -80 ° C.
The Mars atmosphere:
The atmosphere of Mars is very thin with a surface pressure of only 7 9mil • pollen compared to 1,033 mil· pollen Earth's atmosphere. This means it is only a hundredth part of the earth.
The atmosphere of Mars contains an estimated 0.01% of water in vapor form. There are also cold water on the planet's surface, as detected in January 2004.
MARS STATIONS:
Like the Earth's equator of Mars is tilted with respect to the plane of the orbit.
