It seems that we are touching on a theme from cosmic fantasy, where astronauts in deep space are forced to defend themselves from cosmic rays. However, this is a fact! Future missions seek to bring humanity to the Moon and Mars, so new research from the Center for Space Research at the University of New Hampshire warned: the effects of radiation are much higher than previously thought.
The doses received in the last 4 years exceeded the trends from previous solar cycles by 30%. This suggests that the radiation situation is becoming more intense. Particle radiation conditions are an important factor in calculating space travel.
In a recent study, scientists found that a large flux of galactic cosmic rays (GCR) is growing faster and approaching a record. It was also noted that in September 2017, one of the most significant events occurred in the solar energy particle. Because of this, huge radiation doses were released, posing a threat to humans and satellites. Unscreened astronauts can earn radiation sickness or more serious long-term health problems. In 2014, researchers predicted about a 20% increase in radiation dose rate from one solar minimum to the next. After 4 years, their new analysis shows an increase in previous forecasts by another 10%.
For analysis, information from CRaTER on the orbital LRO was used. Scientists also point to an abnormally long period of recent calming solar activity. During most of the space age, our star's activity declined and proceeded like a clock in 11-year cycles with a 6-8-year period of silence. But since 2006, the longest solar minimum and weak activity have been observed.
