Solar Energetic Particle Event Detected on Earth, Moon, and Mars

A recent study has highlighted the risks of space radiation to lunar and Martian exploration, focusing on a Solar Energetic Particle (SEP) event detected on the surfaces of Earth, the Moon, and Mars. The research emphasizes the varying levels of natural protection against radiation on these celestial bodies and underscores the need for effective shielding to ensure astronaut safety in future space missions. Earth's magnetic field and atmosphere provide some protection, but the Moon and Mars lack similar shielding. Without adequate shielding, future lunar missions could face radiation risks during approximately one out of every five SEP events, while extreme SEP events during the journey to Mars or in Martian orbit pose a significant radiation risk for deep space missions.
