Atmospheric Effects of Precipitation through Energetic X-rays

Imaging energetic particle precipitation

The Atmosphere Effects of Precipitation through Energetic X-rays (AEPEX) 6U CubeSat Mission will quantify the energy deposition from the radiation belts due to precipitation, during both quiet and active conditions, and provide spatial measurements of precipitation regions. These measurements will improve our understanding of radiation belt precipitation, radiation belt lifetimes, and the effects of radiation belt precipitation on the upper atmosphere, directly addressing the Heliophysics Decadal Survey Key Science Goal 2: “Determine the dynamics and coupling of Earth’s magnetosphere, ionosphere, and atmosphere and their response to solar and terrestrial inputs.”
