The first flight to Mars would be extremely dangerous to the health of astronauts — no doubt about it. In may 2017, a study on mice showed that members of the first manned mission will be subjected to double the risk of cancer. A new study ESA ExoMars proves that members of the first mission for 6 months will receive 60% more radiation than in my entire career.
Fellow of the Bulgarian Academy of Sciences yordanka Semkova announced that a large part of the radiation will be absorbed by the astronauts during the flight to the planet. Recall that the radiation comes from cosmic rays — charged atoms moving in space.
Radiation dose accumulated by astronauts in interplanetary space are several hundred times more than the dose accumulated by people during the same time period on Earth.
The astronauts will be exposed to radiation even on the surface of Mars. The planet has no thick atmosphere and a magnetic layer capable of protecting them from harmful cosmic rays. That is why scientists have to create strong anti-radiation vests.
In addition to new costumes, scientists are trying to create a cure from the effects of radiation. For example, in may of 2018, staff at the University of California in San Francisco began testing the drug PLX5622. It is expected that it will prevent damage to the nervous tissue.
