DivisionNameLaunch DatePhase
Earth ACT-America
Understanding the terrestrial carbon cycle is essential for diagnosing current and predicting future climate change; however, sources and sinks of carbon dioxide (CO2) and methane (CH4) are poorly known at regional to continental scales. The Atmospheric Carbon and Transport-America (ACT-America) ...

Earth ATom
The Atmospheric Tomography Mission (ATom) will study the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere.
20150401 April 2015 2Development
The Cyclone Global Navigation Satellite System (CYGNSS) will make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes. The goal is a fundamental improvement in hurricane forecasting. The CYGNSS data will enable ...

Earth GOES-R
GOES-R satellites will comprise improved spacecraft and instrument technologies, which will result in more timely and accurate weather forecasts, and improve support for the detection and observations of meteorological phenomena that directly affect public safety, protection of property, and ultimately, ...
20160301 2016 2Development
The Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) mission will allow scientists to gain new insights into the dynamic processes in Earth’s interior, into currents in the oceans, and into variations in the extent of ice coverage.
20180201 February 2018 2Development
Earth ICESat-2
ICESat (Ice, Cloud,and land Elevation Satellite) is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. This mission is part of SMD's Earth Systematic Missions ...
20180601 June 2018 2Development
The North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) is a high-impact, interdisciplinary investigation focused on marine ecosystems and aerosol properties in the climate sensitive North Atlantic. NAAMES will study the annual life cycle of phytoplankton and the impact small ...
20150115 January 15, 2015 2Development
The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is a satellite system used to monitor global environmental conditions, and collect and disseminate data related to weather, atmosphere, oceans, land and near-space environment. This mission is part of the GOES/POES program.
20140331 March 31, 2014 2Development
Earth OCO-3
Orbiting Carbon Observatory – 3 (OCO-3) is a complete stand-alone payload built using the spare OCO-2 flight instrument, with additional elements added to accommodate installation and operation on the International Space Station (ISS).
20161215 December 2016 2Development
Earth OMG
Oceans Melting Greenland (OMG) will pave the way for improved estimates of sea level rise by addressing the question: To what extent are the oceans melting Greenland’s ice from below?
20150401 April 2015 2Development
ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) is a five year investigation with three deployments designed to probe how smoke particles from massive biomass burning in Africa influences cloud cover over the Atlantic. Particles from this seasonal burning ...
20150201 February 01, 2015 2Development
The SAGE III instrument is used to study ozone, a gas found in the upper atmosphere that acts as Earth’s sunscreen.
