Explorers will face dangerous amounts of radiation during their stay on Mars

New insights from Mars Hint Fuel Orbiter show that the flight is secure and that I will help propel astronauts to 60 per cent of the radiation dose for life.

Traveling to Mars is the next colossal step in the house of mankind. In Hollywood, the unique film The Martian and the television series The First show that this is a real difference in forward-thinking logistics rather than a loose dream. NASA is currently moving towards a "Moon to Mars" mission, but the technical obstacles encountered during a mission on Mars are significant. One of the most challenging challenges is the radiation dose that would be encountered by interplanetary astronauts. Meghan Bartels, from Space.com, discovers that the unique knowledge of the European Space Society (ESA) has refined our model of radiation at a given moment of the wandering to and from Mars, and that it has not been infiltrate.

ESA's Exomars Hint Fuel Influence Exploder was launched in 2016 and launched into spherical orbit on Mars after a six-month wander through an interplanetary house. Along the way, an instrument called the Liulin-MO dosimeter recorded the radiation information from the craft and saved the tabs because the TGO reached orbit. Using this knowledge, the researchers say that any interplanetary astronaut traveling the same way would have 60 percent skills. 100 percent of his maximum career dose stapling all the way to and from Mars, not to mention the time spent in the field. the planet is working and exploring.

"Radiation doses collected by astronauts in interplanetary homes could be several hundred times higher than doses collected by people over an identical time interval on Earth and several other cases greater than doses of astronauts and cosmonauts engaged in the International Space Express. Semkova of the Bulgarian Academy of Sciences and senior scientist of the Liulin-MO instrument says in a press release. "Our existing findings that the ambulation itself would provide a very important exposure for astronauts to radiation."

The files save associated radiation ranges detected when the Mars Science Laboratory received identical shuttle assistance in 2011 and 2012.

Sheyna E. Gifford of Astrobiology magazine tells us that we do not think too much about radiation here on the Earth's ground because the extremely strong magnetic field around our planet deviates most of the radiation. But the house problems are different. Astronauts are bombarded by solar energy particles and galactic cosmic rays. A child at Mars might have to go through a CT scan at two dozen examples, which is quite 15 times higher than the physical radiation exposure allowed for plant workers. nuclear.

To protect future Mars-o-nauts, engineers should produce protection against galactic cosmic rays (GCR), but this is easier said than done. The particles are huge.

"They take care of you, you take care of yourself," says Dan Masys of the College of Washington, an American, the biomedical work and computer scientist of Nova. At this point, there is no nice way to protect ships or astronauts against particles.

Rays that are no longer at hand increase the misery of most cancers, but NASA has also identified dozens of different problems related to exposure, including disturbed sleep, cardiovascular and degenerative diseases , infertility, cataracts. According to Mr Masys, the write-offs are a "dealbreaker" for any long-term project for the exploration of homes.

Once the explorers reach the ground of Mars, the radiation will stop no more. Gifford discovers that knowledge of the Curiosity Rover shows that GCR exposure is about half that of the home, but protection against solar energy particles is uneven and unpredictable, which means people will continue to be exposed. ;explode. The ExoMars 2020 mission, which will consist of a single Mars Rover, will consist of an associated dosimeter that will give us even more relevant knowledge about the radiation to which we can interrogate the ground of the crimson planet.
