NASA’s ambitious plans to send humans to Mars as early as the 2030s are facing significant challenges due to radiation concerns. The space agency has long considered Mars as one of the most promising destinations for life beyond Earth, but a recent study published in the Advancing Earth and Science Journal has raised serious questions about the feasibility of long-term human habitation on the red planet.
Researchers combined data from several institutions to investigate the impact of particle radiation on both humans and spacecraft. They found that exposure to radiation would pose a significant threat to human life after just four years on Mars, exceeding safe levels. The study also revealed that spacecraft materials can either shield or increase radiation exposure depending on their thickness.
To mitigate this risk, scientists suggest that missions should be launched during periods of peak solar activity when the most hazardous particles are deflected away from Earth. However, even with these precautions, researchers warn that the technological challenges posed by space radiation remain significant. While a short-term mission to Mars is still considered viable, long-term habitation on the planet appears unlikely.
