ISS shock: The 'big danger threatening NASA astronauts' lives' on space station revealed
The ISS is an artificial satellite in low-Earth orbit that serves as a space station for the five leading space agencies of NASA, Roscosmos, JAXA, ESA and CSA. It is a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields, with astronauts being sent a dozen bottles of wines earlier this week in the latest test. While the effects of weightlessness are well documented, with scientists coming up with several measures to combat the issue, there is another threat that cannot be seen.
Amazon Prime’s “Tomorrow’s World” series revealed a serious issued hindering cosmos exploration.
The narrator explained last year: “For now, no one knows how long man can survive in zero gravity, but in space, a bigger danger threatens astronauts' lives – cosmic rays.
“This particle flux that circulates in the void is capable of penetrating cells and destroying human DNA.
“On Earth, our planet’s magnetic field protects us from these harmful rays.

A bigger danger threatens astronauts lives – cosmic rays
“But when in space for six months, astronauts are exposed to a dose to equivalent to over 600 chest X-rays.”
Cosmic rays are high-energy protons and atomic nuclei which move through space at nearly the speed of light.
They originate from the Sun, from outside the Solar System, and even from distant galaxies.
Scientists at the Nuclear Physics research centre (GSI) in Germany are currently trying to find ways to combat this invisible threat.
The narrator added: “So, before organising longer trips to further away from Earth and its protective environment, scientists from all over the world are trying to find ways to protect man.

“In Darmstadt, Germany, Professor Durante and his team study very special materials, identical sand to that found on Mars and on the Moon.
“These sand replicas interest them because they believe that one day, man could use it to settle in space.”
Professor Marco Durante, head of the biophysics department explained the work he is currently involved in.
He stated: “If you go to the Moon or Mars, you have plenty of this material around you, so you can build your shelters, you can build your houses with this material.
“The question we are trying to ask is if you build your shelter with this material on the planet, can you live safely inside or not?

“This is the big question.”
During the same show, scientists also probed the possibility that living in space could “speed up ageing”.
An experiment carried out on 12 “perfectly healthy men” was intended to replicate the environment of an astronaut on the ISS.
Completed at the Institute of Space Physiology in Toulouse, France, the patients were placed at a decline of six degrees and given different restrictions to test their bodies reaction.
Dr Bareille, who was running the tests, revealed the shocking realities of living in space.
She said: “The result of weightlessness on astronauts in space, or on healthy volunteers, like in our experiment, is quicker ageing.
“They show signs of age acceleration.
“When standing on Earth, there’s more blood in the legs, that in the upper body or head.
“When you are in microgravity, the blood is redistributed, and there is proportionally more of it in the upper body.”
