Providing spacecraft maintenance and operations for Earth Science missions

About ESMO

The Earth Science Mission Operations (ESMO) Project is responsible for spacecraft maintenance and operations for Earth Science missions conducted by the Earth Science Projects Division at the Goddard Space Flight Center.

The ESMO Project plays a significant role during the mission life cycle; from the formulation and approval phases through the implementation and evaluation phases, and eventual deactivation. The Project's role is to ensure the health and safety of the missions it manages by fulfilling the primary operational requirements for each mission, and providing the scientific community with high-quality data products in a timely manner. It also serves as a focal point for the mission on-orbit operations and the definition of support services required.
