A team of international scientists has created the first complete energy spectrum of high-energy protons during a solar eruption near Mars.
The study deepens our understanding of the radiation environment around Mars and its risks to future exploration missions.
China's Tianwen-1 orbiter played a key role in this discovery, measuring particles with energies ranging from 2 to 100 MeV.
The researchers combined data from multiple missions to map the energy spectrum and estimate radiation dose, confirming the reliability of their methods.
