Mars Declared Unsafe for Humans to Live as No One can Survive for Longer than Four Years


The idea of human colonization on Mars has long captivated the imagination of scientists and visionaries alike.

With prominent figures like Elon Musk actively pursuing this extraterrestrial endeavor, the prospect of establishing a human presence on the Red Planet seems increasingly plausible.

However, a recent study examining the feasibility of sustaining human life on Mars suggests that the challenges may be more formidable than anticipated.

Researchers from UCLA embarked on a mission to address two critical questions pertaining to the viability of Mars as a habitable environment for humans. Firstly, they sought to understand the potential dangers posed by particle radiation and its impact on human life. Secondly, they explored whether strategic timing of a Mars mission could shield astronauts and spacecraft from the harmful effects of radiation.

To unravel these mysteries, the scientists employed geophysical models to analyze particle radiation patterns across a solar cycle. They also developed models to assess the impact of radiation on both human occupants and the spacecraft. The study yielded mixed results, with a positive answer to the second question and a negative one to the first.

According to the calculations, the spacecraft should provide adequate protection during the round trip to Mars and back for the astronauts. However, the material used in constructing the spacecraft must strike a delicate balance. If it is excessively thick, it may inadvertently enhance secondary radiation, compromising the safety of the crew. Additionally, the timing of the mission is a crucial factor in mitigating radiation risks.

The researchers recommend launching the expedition during the solar maximum phase when solar activity is at its peak. During this period, the most hazardous particles are deflected, providing a shield against the worst effects of radiation. Nonetheless, the study delivers a sobering caveat: humans should not exceed a mission duration of four years on Mars due to escalating radiation levels.

The findings, published in the Advancing Earth and Science Journal, underscore the hazards of prolonged exposure to radiation. The researchers state, “Our calculations clearly demonstrate that the best time for launching a human space flight to Mars is during the solar maximum, as it is possible to shield from Solar Energetic Particles. Our simulations show that an increase in shielding creates an increase in secondary radiation produced by the most energetic Galactic Cosmic Rays (GCR), which results in a higher dose, introducing a limit to a mission duration. We estimate that a potential mission to Mars should not exceed approximately four years.”

While the study acknowledges the strict limitations imposed by space radiation and the technological challenges associated with a Mars mission, it cautiously asserts that such an undertaking remains viable. As humanity’s ambitions reach for the stars, it is imperative that we confront and overcome these formidable obstacles before embarking on the next great interplanetary voyage.
