Can we live on Mars? The challenges of a second land

With temperatures that can descend up to -125 ° C. Moreover, a severity three times lower than that of the earth and an atmosphere composed of 95 % carbon dioxide, Mars is anything but a hospital planet.

However, some see Mars as a future “second earth”. For example, Can we really adapt human life to these extreme conditions? Similarly, The colonization of the red planet raises colossal challenges.

Why live on Mars remains a distant dream for the moment – Can we live mars? challenges

According to experts. For example, it is impossible in the short term to live on Mars. We are not yet ready to survive in a hostile environment. NASA plans to send the first astronauts to March by 2040. but a real sustainable colonization will take several decades, at least.

Before considering the colonization of March, the objective is to establish a human presence on the Moon. The can we live mars? challenges installation of a prosperous colony on our natural satellite will allow us to test the technologies necessary for. life outside the earth. The moon will serve as a sort of technological. logistics springboard before taking up durably in the direction of March.

Already, you should know that we cannot breathe on Mars. There are 99 % less air on Mars than on earth because the red planet is about twice as much smaller than ours. its severity is lower. It therefore does not effectively retain the light gases that escape in space.

The Martian atmosphere is incompatible with life

As for the composition of Martian air. there are more than 95 % carbon dioxide and only traces of oxygen (about 0.13 %, according to experts). In comparison. earthly air is made up of 78 % diazot, 21 % dioxygen and the remaining 1 % corresponds to other tiny quantities like carbon dioxide.

It should can we live mars? challenges not be forgotten either that Mars is a very cold planet. On the surface, the average temperature is around -63 ° C. However, it can drop to -125 ° C at night or near the poles.

Finally, Mars has no global magnetic field or thick atmosphere to block solar and cosmic radiation. The radiation levels are therefore much higher than those of the earth. It would therefore be necessary to live in underground or sufficiently isolated habitats to limit the effects of these radiation.
