Is it realized on Mars at the current level of technology development?


We answer the question sent by the subscriber:

Marsian’s film One of the best films in the genre of solid scientific fiction of recent years and, when viewed, it can really get the impression that the flight on Mars and the support of the vital activity of people on Mars is a pretty simple task. In reality, everything is somewhat more complicated.

In mankind, there are currently no technologies allowing you to send a person to Mars and return it back. Thousands of various technologies should be created to make it possible.

Most people apparently not completely what is

Below we give a small and far from a complete list of some of the missing technologies necessary to send a piloted mission to Mars.

No country of the world has a rocket that can send to Mars a spaceship is large enough to carry inside people.

Some rockets that will probably be able to cope with this task are currently in development:

At the moment there is no landing module that can safely deliver people from the orbit of Mars on its surface. Marsa, unlike, for example, the moon, has an atmosphere. At the same time, the atmosphere of Mars is not sufficiently dense so that it was possible to slow down, as spacecraft included in the earth’s atmosphere. But not enough sparse so that it can be ignored.

Space agencies sending on Mars Marshowers come up with various intricate landing schemes, I think many have seen various videos on this topic on YouTube.

In the film «Martian» Astronaut Mark Sens lives in a beautiful multicotible spacious residential module. This does not exist anything like that suitable for Martian conditions.

The residential module must provide sufficient protection against radiation, an extremely rarefied Martian atmosphere, to prevent Martian sand and dust from entering the module, maintain a comfortable temperature for astronauts inside and the like. Not to mention the fact that this residential module is needed to deliver and pull it into its surface.

At the moment there are several models of Martian residential modules that are tested in the Gobi desert, on the slopes of Hawaiian volcanoes, in the Arizonian desert, etc. But none of them are ready for practical use in Martian conditions.

There is no rocket that could raise people from Mars and deliver them to the orbit of Mars to ensure return to Earth.

Due to the fact that the attraction of Mars is much weaker than the attraction of the Earth, as well as the fact that the atmosphere of Mars is much more resolved such a rocket will obviously, there will be much less terrestrial missiles, to deliver people to orbit, but still ready to use a rocket for this There is no moment.

There is no spacecraft at the moment, which could support the life of astronauts for many months on the way to Mars and back without periodic replenishment of stocks of products, water, oxygen, etc. from the ground.

In the film «Martian», a huge spacecraft was used, apparently assembled in orbit, running like a ferry between Mars and Earth. At the moment, we have no experience in creating and using such ships and although the experience of building an ISS and a future arrogant base will certainly become extremely useful until technology for the construction of such a ship in humanity.

This is only a small top of a huge iceberg technologies that need not only to develop, but also conduct numerous tests and checks, develop protocols and procedures for their use, etc. With this development, even the above technologies will require tens and hundreds of thousands of unique and complex engineering solutions.

Perhaps the author of the question meant that the modern level of development of science and scientific knowledge is sufficient to develop all or almost all the necessary technologies. With such a formulation, you can agree. The development of all of the above does not require fundamental breakthroughs in science (such as if we needed to develop technologies for travel with superluminal speed).

We need «just» to hone and improve existing technologies, as well as develop new ones on their base. But this process is by no means fast. But subject to sufficient investment, Mars will become a reality in the coming decades.
