Mars is the red planet because iron oxide predominates on its surface. This molecule gives the planet a reddish appearance.
The hemoglobin in the blood also has this reddish color, and it also has iron in its composition.
With iron oxide we can extract oxygen and iron. Oxygen for breathing and Iron for the construction of machines and objects.
The mass of planet Earth is almost ten times that of Mars. Which makes Mars have a third of the gravity of planet Earth.
Several problems occur due to this smaller mass, among them to accentuate the rarefied atmosphere, to assist in the rapid loss of the magnetic field of Mars.
So the planet's core must have lost its spin, possibly due to the loss of temperature and the intensity of the planet's internal pressure.
Thus, it is necessary that the mass of Mars is similar to the Earth's mass, in order to be colonizable.
Mars has two moons called Phobos and Deimos. Which are large asteroids trapped by the gravitational field of Mars.
Mars does not have a magnetic field against the solar wind, as does the Earth, and this makes it easier for gases to be lost in the atmosphere of Mars.
The year of Mars lasts approximately two years on planet Earth, the Martian day is 24 hours. And it is a planet colder than the earth, because it receives half of the sunlight, which receives the planet earth.
This is the planet Mars.
