Projects in Primary Operations

Landsat 9, a partnership between NASA and the U.S. Geological Survey (USGS), will continue the Landsat program’s critical role in providing the longest continuous space-based record of the Earth’s surface. Primary Operations until ( TBA )

ISS Instrument


The SAGE III The Stratospheric Aerosol and Gas Experiment (SAGE)-III mission is an important part of NASA's Earth Observation System and is designed to fulfill the primary scientific objective of obtaining high quality, global measurements of key components of atmospheric composition and their long-term variability. Primary Operations until 2020

ISS Instrument


The TSIS mission provides absolute measurements of the total solar irradiance (TSI) and spectral solar irradiance (SSI), important for accurate scientific models of climate change and solar variability. Primary Operations until 2023



POES is a NOAA reimbursable project, providing critical operational climate data that is used in developing current and extended weather forecasts.



The MetOp satellites provides critical data for weather forecasting. Primary Operations until 2023

The Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) , utilizes lasers and a very precise detection instrument to measure the elevation of Earth’s surface. Primary Operations until 2023

Suomi NPP


The Suomi National Polar-orbiting Partnership (Suomi NPP) provides atmospheric and sea surface temperatures, humidity sounding, land and ocean biological productivity, and cloud and aerosol properties Primary Operations until 2022

Landsat 8

Landsat 8

The Landsat program provides the longest continuous space-based record of Earth’s land in existence. Primary Operations until 2022


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.


Earth Science Data and Information System (ESDIS) Project provides science data to a wide community of users for NASA's Science Mission Directorate.

ESDIS is responsible for processing, archiving, and distributing Earth science data. It provides tools to facilitate the processing, archiving, and distribution of Earth science data. ESDIS collects metrics and user satisfaction data to learn how to continue improving services provided to users. It ensures scientists and the public have access to data to enable the study of Earth from space to advance Earth system science to meet the challenges of climate and environmental change. ESDIS promotes the interdisciplinary use of EOSDIS data, including data products, data services, and data handling tools to a broad range of existing and potential user communities.
