A 2021 coronal mass ejection sent energetic particles to Mars, the Earth and the moon, emphasizing the need to prepare human space missions for the dangers of solar radiation.
bodies. And in the process, it demonstrated the need to protect human space exploration missions against the dangers of space radiation.
"Measurements of high-level radiation events by robotic missions is critical to prepare for long-duration crewed missions. Thanks to data from missions like ExoMars TGO we can prepare for how best to protect our human explorers."Usually, charged particles hit the magnetosphere, a magnetic bubble around Earth, then travel down magnetic field lines and disperse beyond our planet. What this means is that Earth's natural magnetic field shields life from this solar radiation.
One of the adverse effects of radiation absorption is radiation poisoning, which arises due to damaged bone marrow and can trigger symptoms such as infection and internal bleeding. This can be caused by a radiation dose over 0.7 Gray . If an astronaut absorbs over 10 Gray they would likely be dead within 14 days.
The LRO measured the radiation delivered by the Oct 2021 outburst to the moon's vicinity as substantially less than a lethal dose, however, at just 0.031 Gray.
