Why Mars remains inaccessible
Over the past hundred years, humanity has advanced in space exploration. At the moment, large-scale projects for the study of outer space are being developed, but not always our strength and knowledge are enough to implement our plans. Especially as ambitious as flying to Mars. In this article we’ll learn about why humanity has not left its mark on the red planet.
To begin with, it should be remembered that technically we can provide such a long flight. And its very duration dictates certain requirements for equipping the ship’s side, which are difficult to fulfill. Our main task in any case is to avoid risks. Which ones? Let’s talk about this in more detail.
One of the most serious problems is radiation
The space is filled with particles, most of which are solar (from flares on the surface of this star) and general cosmic radiation. They are so powerful that when a ship enters their spectrum, they penetrate inside and provoke changes in the tissues of living organisms on board, cause aging and increase the risk of cancer.
It has been established that with an approximate flight to Mars in two years, an astronaut will receive a fraction of radiation equal to 500 milli-sievers. This unit measures the amount of radiation per person. Attention – the permissible limit value of this norm is 100 millisieverts in five years.
A solution to this problem is sought in the invention of medicines that strengthen the human body against radiation and the creation of light but durable materials for ships, for example, based on polyethylene.
For the human body, the state of soaring in the air is not natural. With a long stay in the air, the skeleton becomes thinner, and the muscles become weak. There may also be problems with vision because of deformation of the eyeball. It is possible to overcome such negative consequences by building a ship imitating earth gravity. However, it will take up a lot of space and will be complicated in its structure.
The nature of the journey itself
A small group of people focused on the ship will be left to their own devices for many months. They will not be able to see the Earth and will not receive gifts from the family, they will be forced to continue their journey to the end. In many ways, the success of the trip depends on the nature of the people who are part of the group.
An experiment has already been carried out in which a group of people was locked in the room for a while, simulating a flight to Mars. Some showed themselves on the good side, others fell into depression. As you can see, everything is rather complicated.
It is worth noting but only a brief overview on this topic. NASA identified 32 risks, 232 gaps in scientific knowledge and 1097 tasks that need to be addressed to achieve this mission.
