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. As the NASA program evolves it will leverage the lessons learned from the current missions and plan for adjustments to future objectives to meet the needs of the USA and the Earth science community. Orbital ATK is sponsoring a limited number of box lunches.
