We are accustomed to earthly rains, but the cosmic one is becoming the greatest threat to the lives of astronauts. The fact is that it is a question of radiation rain. The NASA program is creating a model of cosmic radiation to understand how to secure a trip to Mars for the crew.
Radiation is one of the main obstacles to space travel. It is enough to leave a near-earth orbit and the risk to health increases dramatically. The Earth is protected from solar radiation due to the presence of the magnetosphere. However, in space, we are confronted with ions that can pass through the skin and infect cells and DNA. This may manifest in astronauts during aging, or it may result in radiation sickness during a mission.
Radiation beats the central nervous system, the cardiovascular system and impairs blood circulation. Recent research at NASA's lab helped to understand exactly how radiation affects the body.

Recent experiments best mimic the health effects of long journeys. The trajectory of the ions resembles rain or light rain. Models are able to display these types and compare the effects. This brings us to a new level of understanding of the problem, because we were able to recreate the space environment in the laboratory.
The Galactic Cosmic Ray Simulator was upgraded at NASA's Space Radiation Laboratory. Now you can recreate the necessary conditions in a few minutes.
The ability to create the necessary conditions allows for more accurate testing of protection and improving their effectiveness. In addition, cancer researchers can test a variety of treatments for tumors with heavy ions.
Do not forget that NASA is planning to launch lengthy missions, which means we need protection from space radiation. If astronauts encounter a problem, they must be confident in their safety. New methods will reduce the health risks during missions.
