But in addition to drinking and breathing, it is necessary to eat and get food, since only a few rations can be brought from the Earth for the first few moments. A second group of four boys and girls will then take care of learning and improving the cultivation of vegetables, which in all probability will be the basis of the diet of future terrestrials on Mars, vegetarians by force of circumstances.
The third group will deal with understanding how to test the physical and mental health of the crew, a difficult task given the strong differences in environmental conditions between Earth and Mars, just think of the completely different atmosphere, not breathable for us, and very gravity. reduced, less than a third of what we are used to living and moving around.
The fourth group deals with the rover, the vehicle that will have to move on the planet, a model of course, but with excellent characteristics, in short, the fleet of the future Martian settlement, if we want to define it that way, which allows excursions to the red planet. Particular attention the boys and girls will have to pay attention to the need to program the rover accurately, to prevent it from being damaged by traveling in the harsh Martian soil.
The last group of four would-be Martians will have to take care of the control of the mechanical arm, in fact a robot, which will carry out the work outside the human settlement, the astronaut house and outbuildings. The first task will be to clean up, as the abundant Martian dust is continuously raised and deposited on the solar cells for the production of electricity.
Although not dense and unbreathable, the atmosphere of that planet is in fact the site of sudden winds, even small whirlwinds called sprites, which certainly do not cause concern, but raising clouds of dust dangerous for the equipment necessary for survival.
