NASA and ESA Exploring New Joint Satellite Mission Concepts
NASA and ESA Exploring New Joint Satellite Mission Concepts About the NASA NASA and ESA (European Space Agency) have worked together on multiple missions to advance our understanding of the Sun and its effect on Earth. To continue this collaboration, the two agencies formed the ESA/NASA Lower Thermosphere-Ionosphere Science, or ENLoTIS, working group in May 2022. In this working group, the agencies are exploring future lower thermosphere-ionosphere (LTI) satellite mission concepts. The aim is to improve our understanding of ion-neutral interactions in the “transition region” between Earth’s atmosphere and space, at altitudes from approximately 60 to 125 miles (or from about 100 to 200 km) altitude, while complementing other missions in development, including the Geospace Dynamics Constellation (GDC) and the Dynamical Neutral Atmosphere-Ionosphere Coupling (DYNAMIC) mission. The working group enables coope...
