Atmosphere-Space Transition Region Explorer
Atmosphere-Space Transition Region Explorer(ASTRE) is a mission concept proposed in 2011 to NASA'sMedium-Class Explorers program(MIDEX) to study the interaction between the Earth's atmosphere and the ionized gases in outer space in an effort to understand how space-induced currents in electric power grids originate, as well as improvesatellite dragmodels.[1]The spacecraft would measure ionized gases within the transition region/boundary layer between 150–250 km altitude.[2][3]The concept was not selected for development at that time.
