Journey to Mars may not be the best thing for the human mind, new research reveals – Technology News, Firstpost


A study found that going to Mars would do no good to humans and their brains.

The study was conducted at a new neutron irradiation facility to simulate cosmic radiation. Male mice were bombarded with low radiation for six months. After this period, the researchers found that the signaling in the prefrontal cortex and hippocampus was disturbed by radiation. This affected their memory and learning abilities. They also noticed that the mice were anxious, meaning that the amygdala was affected.

Charles Limoli, a radiation oncologist at the University of California said CNN, "These charged particles are very dangerous. The reason is that they are very vigorous and completely ionized and when they travel through the body, they produce this type of damage that makes the cells and tissues of your body very difficult to find. "

Traveling to Mars may not be the best thing for the human mind, new research finds

Traveling to Mars exposes people to more intense radiation than the ISS.

Researchers believe that every fifth astronaut would face anxiety. One in three would have to deal with memory problems, and they would all struggle to make decisions, which is important when you set out to settle on another planet.

Limoli said the best of shields could offer only the limited radiation protection that would come when traveling to Mars.

The famous NASA twin studyconducted on twin astronauts Scott and Mark Kelly, also examines the impact of space on the human body. They sent Scott to the ISS for a year. Mark, his twin remains on the ground. As twins, they were genetically very similar, allowing scientists unprecedented access to a control object to study the effects of long-term space travel.

Scott Kelly's body has been found to have several problems with muscle and bone strength, not to mention cell damage. However, they found that within six months Scott's body had normalized and had no long-term side effects. This test was limited to the long-term effects of low gravity environments.

But it's not the same as going to Mars. Astronauts living on the ISS are not facing the same level of radiation as those who would go deep into space. The ISS is protected as it exists in low Earth orbit (LEO).

There is a shield protecting the Earth from high energy particles (radiation) in space. This natural, impenetrable barrier looks extremely effective. It is based on a phenomenon called 'plasmospheric hiss', which is a low frequency electromagnetic wave that absorbs high energy particles. This phenomenon sounds like hiss, hence the term.

This barrier is extremely rigid and almost impenetrable in terms of high-energy electrons, which struggle to get more than 11,000 km closer to the earth's surface.

The findings of this study were published in the magazine eNeuro,
