Solar Eruption Sends Shockwaves Across Earth, Moon, and Mars

A solar eruption detected simultaneously on Earth, the Moon, and Mars highlights the importance of preparing for space radiation during human exploration missions. The eruption, which occurred on October 28, 2021, was measured by spacecraft including ESA's ExoMars Trace Gas Orbiter, NASA's Curiosity Mars rover, and the CNSA Chang'e-4 Moon lander. The event, known as a ground level enhancement, allowed energetic particles from the Sun to reach the surfaces of the Moon and Mars, emphasizing the need to understand the impact of solar events on astronauts. Protecting astronauts from radiation is a crucial task, and ongoing research and measurements are being conducted to better understand and predict intense radiation events in space.
