5 Big Risks for Mars Astronauts (Video)



The universe may well be sophisticated, but it can be deadly for human researchers.

While NASA and other space organizations have learned how to protect human life on a relatively short mission such as the travel of the Moon and the International Space Station (ISS), scientists still need to plan for a longer time traveling and studying through deep space. On the possible mission of Mars, for example, NASA's human research program expects the human crew to have five major risks. The program studies and develops best practices and techniques to support safe human space travel.

For now, the program is studying ways to prevent these risks listed below. For the human mission to succeed Red Planet, these five risks need to be carefully managed. [Space Radiation Threat to Astronauts Explained (Infographic)]

Most people know that you may get sick due to excessive radiation exposure, but there is nothing compared to the level of radiation we are experiencing on Earth. Those astronauts will be exposed On the journey of Mars. Radar radiation emitted by people living on Earth is more rigid and harmful.

Astronauts at the International Space Station, located within the Earth's protective magnetic field, are exposed to radiation that is back to Earth, up to 10 times, NASA officials said in a statement that the agency's Human Research Program

Anyone traveling through deep space will take more risk than radiation exposure. Outside the protective shield of the Earth, radiation can increase cancer risk and damage the person's central nervous system (which may result in changes in cognitive function, reduced motor function and behavioral changes), NASA's Human Research Program said. Other risks of exposure to such high radiation include nausea, vomiting, anorexia, fatigue, dementia, cardiac disease and circulatory disease.

So NASA is studying how the human body and mind are affecting, so that the agency can find ways to control the effects and astronauts keep them safe because they travel in deep space.

All potential hazards for a long mission in deep space do not come from the hidden dangers of the universe. Some risks are also caused by humans. NASA's Human Research Program states that while people's groups are no longer limited to a small space, behavioral problems are inevitable. Therefore, astronauts in every group are carefully selected, trained and supported to move into space together for a long mission. The future employees selected to go to Mars will be examined more closely as they will travel longer than one another. Other space missions will be more and more limited and limited.

Scientists know that isolation can reduce the development of mood, cognitive, psychosis and interpersonal interaction, as well as sleep disorders. NASA anticipates Mars's mental journey, as astronauts expect to be an alternative between heavy load and bore period. Fresh food shortages can add to the sense of monogamy and give nutrition impairments to astronauts, which can contribute to mental and physical illness. People's groups can be confused with confusion and emulsion.

Therefore, NASA has studied how to differentiate groups of people over the years and how bonding affects them, and the agency has developed methods and techniques to help. NASA officials said lighting, movement and sleeping were important to help keep the crewmers, which are different, to keep them in the best possible mental health. The crewmans are encouraged to keep a journal on the spacecraft, providing a constructive place for the astronauts to further their dismay. NASA also uses devices on spacecraft to monitor the three factors – lighting, movement and sleep – which will help in a longer, deeper space mission.

If astronauts travel to Mars, before any humans go, they will go a long way in that space. The moon is 239,000 miles (380,000 kilometers) away from Earth, while Mars is 140 million miles (225 million kilometers) away. This means that once they are on the red planet, astronauts have no way to re-apply their resources. Therefore, they will become significantly self-sufficient to survive, and will need to organize the Red Planet's mission nicely.

According to NASA's Human Research Program, there will be a delay of 20 minutes for any communication between Mars and Earth. In case of equipment failure or medical emergencies, crew must have the ability to handle everything themselves. Food will be pre-arranged for the whole trip, and there will be a need to provide medicines for many possible problems.

The Human Research Program currently studies what kinds of medical problems can occur in space in the six months of travel to Mars. In this way, NASA can plan what kind of procedures, equipment and medicines it will need, as well as what medical skills the crew will need.

Astronauts who travel in space now have ultrasound to observe how their body changes in the reaction of the Earth's atmosphere. And the Human Research Program also examines ways to improve food formulations, processing, packaging and maintenance, so nutrients remain stable for a long time, as well as retain their unity on drug delivery methods and long-term space missions.

On the journey of Mars, astronauts will face three different gravity fields. Space tourists will start in the Earth's gravity field, which is about 10 Newton / Kilogram. During the six month journey they will experience less weight than a deep space. And they will live and work in the field of gravity, while Mars will be as strong as three-eighths on Earth. Every time gravity changes, astronauts will have to adapt their body. According to the Human Research Program, the hand-eye coordination of a person changing from one gravitational field to another influences the balance, movement, movement and space. It also affects the muscles, bone and heart. Without gravity, the bone density of a person decreases by 1 percent every month, because its body does not work against force.

The Human Research Program is studying the effects of spaceflights on both Earth and beyond. This program monitors the astronauts' fine motor skills, fluid distribution, fitness and exercise levels, vision and answers to pharmaceutical drugs. The crew selected for the journey of Mars will need to stay, work and explore in the three gravitational fields on Mars and on the road roads.

It is no secret that space is inappropriate for humans, that is why astronauts need specialized spaces to stay out of the space station. Astronaut spacecraft also plays a major role in keeping the researcher alive, because the temperature, pressure, light, air, noise, and unhealthy space in the pot are all the replicated positions on the planet.

NASA is expected to take the final journey of Mars in about six months, which means that the space spaces of astronauts must be enough to keep the vacant space healthy for both physically and mentally healthy. Therefore, living conditions in space need to imitate as much as possible on Earth, and space travelers need to be encouraged to be active and motivated. To use limited resources in the technology of existing and future spacecraft, the astronauts will need to turn carbon dioxide into respiratory air and water in their urine, for example – and also keep the environment comfortable. The ISS, for example, uses the LED light system, which is designed to copy the light on Earth.

The technology at the space station also inspects the air quality of the station to check the health of astronauts. NASA scientists analyze the astronauts' blood and urine samples, as well as to monitor their health and strain levels. In space, according to the Human Research Program, stress hormones are enhanced and they can change the person's immune system and make them more susceptible to allergies and other illnesses. Space also makes it easy to transfer from person to person for the micro-organisms on your body. Therefore, ISBs are assigned to analyze microbial populations on-board.

In the future, for deep space missions, such as travel to Mars, each of these risks has to be addressed to ensure that the astronauts can live.
