The Atmosphere-Space Transition Region Explorer (ASTRE) mission would study the interaction between the Earth’s atmosphere and the ionized gases of space. By flying excursions deep into the Earth’s upper atmosphere, its measurements would improve satellite drag models and show how space-induced currents in electric power grids originate and evolve with time.Technical report
