Cosmic rays pose a significant challenge for human space travel beyond Earth, especially to Mars, due to their damaging effects on living organisms and equipment. Current physical shields are insufficient against high-energy cosmic rays, prompting research into biological protection methods such as antioxidants, hibernation-like states, and leveraging organisms like tardigrades. Advances in simulation and accelerator technology, along with increased research investment, are crucial for developing effective protection strategies to enable safe long-duration space missions.
