The U.S. National Aeronautics and Space Administration has formulated two ionosphere‐thermosphere (I‐T) spacecraft missions to solve major unresolved I‐T problems. These missions are the three or four spacecraft Geospace Electrodynamic Connections (GEC) mission and NASA’s Living with a Star Program’s two spacecraft Ionosphere‐Thermosphere Storm Probes (I‐TSP) mission. The spacecraft on these missions will measure in situ all of the neutral atmosphere and ionosphere properties, including densities, temperatures and the ion and neutral velocities, needed to understand the local state and dynamics of the system. The two I‐TSP spacecraft will focus on the middle latitudes. The goal of I‐TSP is to understand the physics of communications‐affecting ionospheric structures. On the other hand, the multiple spacecraft of GEC will also carry electric field and energetic charged particle instruments to measure the magnetospheric energy inputs and carry sufficient propulsion to make several weeklong deep‐dipping campa... |
