The radiation belts present a challenging problem for measuring magnetosphere dynamics in space. Current measurements can only draw small-scale views of the wider picture of radiation belt dynamics. However, the particles in the radiation belts are sometimes launched into the atmosphere, producing x-rays that can be imaged on very large scales. The AXIS instrument aboard the upcoming AEPEX satellite mission will present a new method of viewing these x-rays to deduce wider behaviors of the radiation belt particle populations that produced them. This poster discusses the power of our novel optical system and its capability to provide a greater view into the grand picture of radiation belt dynamics.
