If you encounter aliens, will people die of stomach cancer?

The dream of space travel, approaching humanity's alien life can go bankrupt because even going to Mars can cause us to die of stomach cancer - according to NASA.

New research by the US Aeronautics and Space Agency (NASA) shows that people may not be healthy enough for a trip to any other planet , even the "neighboring" Mars - a planet with proof of existence and still has good conditions to support life.

Specifically, NASA's team discovered that cosmic radiation would strike the astronaut's digestive system directly , especially the intestines and stomach, as soon as they were on their way to Mars or a planet farther away.

Cosmic radiation is one of the biggest obstacles to a trip to any other planet.

These radiation will cause the stomach to decline, even lose its ability to absorb nutrients or progress rapidly. Travelers can die from illness shortly after landing on another planet, on the way back or even on the way.

To study, scientists have captured mice exposed to low-dose exposure to GCR, the most harmful form of cosmic radiation that humans will inevitably face when they explore another planet.

This radiation carries heavy ions such as iron and silicon, like micro-bullets, moving super-fast and having greater destruction than either X-rays or gamma rays.

On Earth and the surrounding space, we are protected from these radiation by the strong magnetic field of the Earth, causing the radiation to deflect. However, devastation will occur if the spacecraft carries people away from the protection of the parent planet. The mice in the experiment were rapidly depleted because their intestines could not absorb the nutrients they were eating, and the blocks formed in the digestive system.

Dr. Karmal Datta, head of NASA's Specialized Research Center (located at Georgetown University in Washington DC, USA), admits: "With current shielding technology, it is very difficult to protect these practitioners from the adverse effects of heavy ion radiation ".

There are currently a number of drugs developed to combat this but still not strong enough to ensure a successful space exploration. Modern techniques only help protect astronauts from damage during close trips, such as on the moon, where the earth's magnetic field also protects people somewhat.

Scientists insist that Mars plans and more distant plans such as exiting the solar system, seeking extraterrestrial life . be done, science will have to find a way to protect people before harshness of the universe, parallel to the development of moving vehicles.
