The colonization of Mars

The colonization of mars.


On September 27th, 2016, in the IAC (International Astronautical congress) in Mexico, Elon musk announced that the objective fixed for his spaceX company and his collaborators will be of colonized Mars before 2024.

His motivation is clear: ” if we always stay on Earth, there will be at the end an event of massive extinction. The alternative is to become a civilization travelling in the space, and a sort multi-planets. It is what we want. ”

  1. The first problem which appears in such a project is the means of transportation.
  2. The second is the life on the planet.
  • How to take enough Man towards a destination which is at best in 55,7 million kilometers?
  • How to survive extreme conditions?


… How to come back to earth?


The launch.

SpaceX answers with his “Interplanetary transport system”, a system based on a “double launch”. The images speakfor themselves. I let you look at it before we get into detail.

The video of presentation of the “Interplanetary  trnasport system”.

The spaceship which you see in the beginning of video is 122 meters high and embarks at least 100 people. Enfaite, the only spaceship is 49,50 meters high and 17 meters in diameter but it is necessary to count the propellers which will produce a push of 28,730,000 lb. Elon Musk announces that would be needed 1 million people to be able to establish a colony on Mars that is 10 000 journeys of 100 people!

Once the spaceship placed on orbit, the propellers get loose to return on Earth.
A fuel tank rose on propellers to be sent back directly in orbit to reload the sapceship. The reservoir returns on Earth, the spaceship begins its long journey for Mars.

Immediately after the departure, the spaceship is going to display solar panels for trapping energy from the sun.

The cruising speed will be 62 634 mph.

Once arrived on Mars, the spaceship will penetrate into the Martian atmosphere with an outside temperature of 3,092 °F … The Martian life will begin then.
I should rather say the industrial life because to be able to assure a potential return or move between planets, the colonists will have no other choices which to produce their own fuel by means of the resources present on Mars such as the water and the carbon dioxides.
This solution obliges the future colonists to embark enough equipments for building autonomous systems which can harvest Martian resources but also transform them.

If the resources present on the spot are not sufficient), the colonists cannot come back to earth. They inevitably have to turn to systems self-sufficient and assure the maintenance.

It is obvious that such a project is going to take a long period of time (because the optimal period for a take-off is every 26 months!) but also be very expensive.
Today with our  technologic ways, the optimistic cost of a journey on Mars for a single person shall raise(bring up) to 10 billion dollars. Elon musk wants to come down to 200 000 dollars.
He hopes interested the financial private sector to find investors, he asserts saving up from his part on his to be able to invest in the multi-global life project.

Indeed the spaceship would be capable of settling on Europe, the moon of Jupiter but also Titan and Encelade, the moons of Saturn.

The life on Mars.

During its presentation, Elon Musk did not linger over the question of the colony. And nevertheless, the inhabitants of the planet Mars are going to have to create some energy, the food and the oxygen in a permanent and viable way.

The average temperature is of -81°F (which comes down in -207°F) and an atmosphere consisted to 96,0 % of CO2. The water very becomes scarce and in the form of ice but its presence was declared well and truly by the NASA. Indeed, we can see the presence of dark stripes on this image taken by HiRISE. It leaves some hope for the future colons to stock up with water

Little dark stripes which show the presence of water. 


As for the energy, it is necessary to remember itself that Mars is more distant than the Earth with regard to the sun, the beams will be less strong but it will always be possible to benefit from it. The collected electrical energy can serve to feed obviously all the electronic systems which will allow the recycling of the water and the air.

The solar system.

For the food, we still have no information on this matter. Elon Musk announces that if we arrive at such a level of technology by building the “Interplanetary transport system”, the food will not be a problem.

We can already imagine systems which hydrate by condensation the dirt of the earth imported as we can see in “The Martian”.

The agriculture in condition spatial is at present at the heart of the searches and in already showed his ability. We think that it will be the main source of nutrition for a long moment.
But there is an other solution which are still in the shade because she are not still viable because of their cost: the cloning of stem cell. The researchers succeeded all the same in creating a steak only from stem cell!

But will these systems be sufficient to assure needs in food of the Martian population? And if there is a failure? And if we do not succeed in producing enough oxygen and energy?

The life on Mars is a question which engenders it thousands of others and which is going to ask for a lot of work and calculation to be able to end in viable systems to assure the life.
The planet Mars presents little exploitable resource what obliges the teams to embark many material and resource the time to become established.


In 12 years, the take-off of the first spaceship aimed at Mars, will be a turning point in the history of the humanity.
To have US $200.000 in pocket and to want to leave in several about ten millions of kilometers without having the guarantee of a potential return: you will be authorized to leave for Mars in one of the spaceship builds by the company SpaceX.
