IDXChannel – For Explorer space, there is good news here! A research team from the University of California, Los Angeles has investigated that the number of radiation from mars should be harmless to explorers as long as the mission lasts less than 4 years.
Earth humans are lucky because this planet has a magnetosphere that protects its creatures from radiation. But, if you are traveling outside like Mars, then man can be exposed to radiation, as quoted from Digital Trends.
Unfortunately, researchers are still in the early stages of knowing this effect. The tricky problem is that there are actually two different types of radiation: Energetic particles from the Sun and galactic cosmic rays.
The study’s authors say it would be best to send a mission to Mars during solar maximum, when the Sun is most active. Because, the activity of the Sun can deflect some of the more dangerous particles from outside the Solar System.
Scientists have shields to protect spacecraft and astronauts from radiation. So the researchers modeled how much radiation astronauts would be exposed to on a round trip to Mars using current shields.
They found the relatively thick shield would help keep astronauts safe as long as the voyage didn’t last more than 4 years in total. However, making the shield too thick will actually be more dangerous because it will increase the secondary radiation exposure.
“This study shows that while space radiation imposes strict limits on how heavy a spacecraft and launch time can be, and it presents technological difficulties for human missions to Mars, such missions are feasible,” said Yuri Shprits, a UCLA research geophysicist. and co-author of the paper.
