Recent research by University of California researchers shows that if the duration of the trip to Mars in accordance with current safety protocols is less than four years, astronauts’ health will not be endangered and they will be able to experience safe space travel without harm to their health.
One of the biggest obstacles to traveling to Mars is worrying about the impact of potential radiation on human health. There is not much information about the impact of life on Mars on the health of astronauts. Toxic dust on the planet or deadly radiation can be dangerous to human health.
A team of researchers at the University of California, Berkeley, is investigating the puzzle and examining the amount of radiation that Martian astronauts are exposed to. Research results They show When the mission to Mars takes less than four years, the radiation is no longer unsafe and does not harm human health.
The magnetosphere protects us from radiation, but outside the Earth this situation changes and astronauts are exposed to various radiations that do not yet have accurate information about its impact on human health.
It can be said that there are two different types of radiation: energetic particles of the sun (SEP) and galactic cosmic rays. Researchers say the missions are best done during the maximum solar cycle. The maximum solar cycle is a regular period of maximum solar activity during the 11-year solar cycle. At this time, a large number of sunspots appear and the output of sunlight increases by about 0.07%. During this time, some more harmful particles are deflected out of the solar system.
We use protective technology to protect astronauts and spacecraft from space radiation. Researchers have modeled the amount of radiation that astronauts are exposed to with the same shields.
The modeling result showed that relatively thick shields can protect us as long as the total travel time does not exceed 4 years. Of course, the question may come to your mind why not increase the thickness of the guard to increase the duration of the mission. Taking such an approach can be more dangerous as it increases the likelihood of exposure to secondary radiation.
“Based on the results of this study, technological problems for space travel will be solved, and such missions will be feasible with additional studies,” said Yuri Shpritz, a UCLA geophysicist.
