The NASA Earth science flight program is a dynamic undertaking consisting of a large fleet of operating satellites, an array of satellite and instrument projects, a robust airborne science program which advances the use of satellite data, and a massive data archiving and distribution system. NASA’s fleet of 19 operating missions provides a wide range of scientific measurements obtained from dedicated Earth science satellites and the ISS. Projects in development are divided into categories: 1. Earth Systematic Missions (ESM) 2. Earth System Science Pathfinders (ESSP). The Earth Science Flight Program benefits from investments by the Earth Science Technology Office (ESTO) to develop and demonstrate cutting-edge technologies that can be applied to future NASA Earth science measurements/missions. The Town Hall will be conducted by Eric Ianson, of the Earth Science Division, NASA HQ, with time for audience participation. Orbital ATK is sponsoring a limited number of box lunches.
