According to the data transmitted rover Curiosity, the radiation levels on Mars, roughly correspond to the parameters that occur in Earth orbit, including the International Space Station. Consequently, future colonizers of the Red Planet should not have major problems with radiation emission when working on Mars for a six-month mission they receive about the same amount of radiation as the ISS.
Similar findings at NASA have made on the basis of the first studies on the surface of Mars. As described in the American space agency, the rover Curiosity — is the first device that measures in real time the background radiation directly on the surface of Mars, being in the same conditions as the possible future astronauts. In any case, NASA have concluded that life on Mars would be impossible, since the radiation level here is different from the ground, and it can threaten yield diseases. But to be here on a rotational basis — for 5-6 months, it is realistic.
"Absolutely it can be argued that the astronauts can live in the modern Mars" — said Don Hassler, a researcher at the Southwest Research Institute in Colorado.
Hassler is a senior research specialist for the project Curiosity RAD (Radiation Assessment Detector), in which the rover monitors background radiation on Mars and tries to discover the changes in the dynamics. In addition, here, scientists are trying to understand which part of the Martian radiation less actively and steadily, in future manned missions to focus precisely on the region.
Hassler said that his team was engaged in a comparison of background radiation on the ISS and Mars. Scientists say that the Earth's atmosphere due to the dense background radiation on Earth in general more peaceful and stable, while on Mars more significantly affected by cosmic radiation. NASA says that the radiation on Mars is only half as active background than in space, because during the flight capsule Curiosity also measured the cosmic radiation on the Earth-Mars trajectory.
"The atmosphere of Mars — that's about 1% of the Earth's atmosphere, so this thin Martian layer can not provide reliable protection against solar radiation and cosmic rays. We will have to see how things are on Mars with daily radiation and how we can best defend themselves from it, "he says.
According to him, as on Earth, Mars background radiation during the day varies by 5-6%, but in contrast to the vibrations of the earth radiation on Mars is the main reason for that is the thickness of the atmosphere, which often varies.
NASA said that by the end of December Office has received a more holistic view of radiation on Mars. "Every day we get more data. We have emerging information about how the Martian radiation associated with solar emissions. In the future, this information will be systematized, "- says Hassler.
