The European Space Agency (ESA) has detected a solar eruption that simultaneously reached Earth, the Moon, and Mars, highlighting the dangers of space radiation for human exploration missions. The event occurred on October 28, 2021, when a coronal mass ejection from the Sun spread over a wide area, allowing energetic particles to reach the surfaces of the three celestial bodies. This marks the first time that a solar event has been measured simultaneously on Earth, the Moon, and Mars. The measurements, taken by various spacecraft including the ESA's ExoMars Trace Gas Orbiter and NASA's Curiosity Mars rover, provide valuable insights into the impact of solar outbursts and the role of a planet's magnetic field and atmosphere in protecting astronauts. Understanding these events is crucial for future crewed missions to the Moon, as radiation exposure can lead to radiation sickness and even death. The ESA is actively working to develop radiation detection instruments and protective measures to ensure the safety of astronauts during space exploration.
