"Triple Impact: Solar Eruption Reveals Perils of Space Radiation on Earth, Moon, and Mars"

A solar eruption in October 2021 was detected on Earth, the moon, and Mars simultaneously, providing valuable insights into how a planet's magnetic field and atmosphere protect against space radiation. The eruption, known as a coronal mass ejection (CME), demonstrated the need to protect human space exploration missions from the dangers of space radiation. While Earth's magnetic field shields life from solar radiation, Mars and the moon lack a magnetic field, making them more susceptible to charged particles. Understanding the impact of solar radiation on these celestial bodies is crucial for future crewed missions. Measurements taken during the eruption showed that the moon received a radiation dose below the lethal level, while Mars' thin atmosphere reduced potential radiation absorption significantly.
