Space Radiation May Be More Dangerous for Astronaut Than We Imagine

University of New Hampshire researchers have recently claimed that there is as a minimum 30 percent more dangerous Space radiation in our solar system than we have imagined before, which may cause a danger for both humans and satellites who venture there. According to the Researchers astronauts may obtain different kinds of space radiation sickness or maybe more serious long-term health effects, including cancer and damage to the heart, brain, and central nervous system indicated Nathan Schwadron, a space plasma physics professor at UNH and lead author of the study. He said “The radiation dose rates from measurements obtained over the last four years exceeded trends from previous solar cycles by at least 30 percent, showing that the radiation environment is getting far more intense,” “These particle radiation conditions present important environmental factors for space travel and space weather, and must be carefully studied and accounted for in the planning and design of future missions to the moon, Mars, asteroids and beyond,” he added. Both concerns are very serious, but what they are seeing in deep space is that over time, radiation seems to be getting worse. Why is it getting worse? The University explained in a statement that the sun’s activity has been low, the lowest it is ever been during the Space Age, which began in 1957 with the launching of Sputnik, the world’s first satellite. That is bad because an active sun intensifies the sun’s magnetic field, which shields our solar system from cosmic rays. “When we started sending human beings to the moon in the late 50s, the solar activity cycles were fairly strong, so the number of cosmic rays were lower” Schwadron said. “But now the cosmic rays number is going up.”
The health problems caused by space radiation may lead to other problems for space mission. The health effects can affect the ability to make decisions, they can affect the way they interact operationally on a mission.

The researchers collected radiation data from the Lunar Reconnaissance Orbiter.

At the end we would like to call you attention the warning of Nathan Schwadron “This is really just something we need to understand so we can better plan for and design missions,” “There are certain ways we can calculate to build better models, and that will allow us to better plan for what the needs are for spacecraft and shielding.”
