(ORDO NEWS) — Experts from different countries conducted a general study that helped assess how space radiation can affect human health. This took into account how the crew members of a mission that could go to Mars would feel. Researchers managed to establish the approximate amount of time that a person can spend on the surface of this desert planet, so as not to cause too much harm to their health.
Scientists have concluded that the duration of flights to the Red Planet, which will be controlled by the pilots, cannot be more than four years. The reason for this is the too high level of radiation, which will negatively affect the state of the astronauts. Experts published the results of the study in the scientific journal AGU Space Weather.
An analysis was carried out of two types of radiation, which are considered to be the most dangerous for humans. These are SCR – solar cosmic rays, as well as GCR or galactic rays. It is worth noting that the intensity of the latter will completely depend on how active the Sun is. In this case, galactic radiation negatively affects not only the person himself, but even the used spacecraft.
A flight to Mars takes about 9 months. At the same time, experts called the solar maximum the optimal time. GCR will not be so intense due to the fact that it is neutralized by less dangerous solar radiation. At the same time, the duration of the mission should not be more than four years, because after this time, the radiation level will begin to increase rapidly.
