How dangerous is the radiation on Mars?

most Likely, the future colonists on Mars will love
One of the most ambitious goals of mankind is to send the first humans to Mars. We recently told you about his intention to send humans to the Red planet said , and the plans programs of NASA Artemis specify even a hypothetical period of this historic event — 2030-ies. But if the main criterion of any space flight is the safety of the astronauts, the arrival at such an unfriendly person to the planet as Mars would put the lives and health of future space travelers at risk.
Cosmic radiation — the main problem of the future colonists
Space is fraught with many dangers for humans, but the most serious problem is cosmic radiation. In its simplest form, cosmic radiation — it is a form of energy, which may consist of electromagnetic waves or particle rays. The earth protects us from the harmful effects of this radiation, but once astronauts sit in a spaceship and leave this protective bubble, they are exposed to various types of cosmic radiation. Moreover, according to recent research, cosmic radiation affects the brain. Thus, the danger to future space travelers will come upon them before the arrival to Mars.
The Atmosphere on the red planet are not so strong as the Earth's atmosphere. In its composition it is more like the atmosphere of Venus, and consists of 95% carbon dioxide. And the actual absence of a magnetic field on Mars suggests that a large part of the surface of Mars is exposed , which comes from several sources, including our Sun. However, other stellar objects outside the Solar system, such as supernovae, are the source of radiation.
Space is a very unfriendly place for Homo Sapiens.
How space radiation affects health?
Radiation penetrates the DNA molecules are permanently changing and damaging them. Some of the main health problems associated with exposure to space radiation include increased risk of cancer, impaired motor function and behavior, neurological disorders and death. Studies on the effects of radiation on human health is limited, given the small sample (in the end, not many people were on the moon). But several studies have shown .
Even in spite of the problems, NASA's InSight from cosmic radiation does not suffer.
So, according to the results of 2016, published in the journal Scientific Reports, the astronauts of missions "Apollo" have suffered from diseases of the cardiovascular system, which often cause premature death. These health problems, according to scientists, could be caused by cosmic radiation. Moreover, those who have gone on a long space flight, and remained in low earth orbit, 43% often faced with the development of cardiovascular diseases. But how to resist cosmic radiation?
One of the best elements to resist such harmful radiation is hydrogen. Therefore, scientists are experimenting with the creation of the suits of hydrogenated nanotubes of boron nitride, which is not only durable, but also extremely resistant to cosmic radiation. Similarly, this material is ideal for facing the spacecraft. Anyway, today researchers have many ideas for limiting the space radiation on Mars, but how they will be feasible, we will know soon.
