The University of Oklahoma has partnered with NASALockheed Martin Advanced Technology Center, and SES Government Solutions to develop the Geostationary Carbon Cycle Observatory (GeoCarb), a first-of-its-kind space Earth science mission.

A hosted payload, scientific observatory ‘GeoCarb’ will be placed on a commercial communications satellite to study Earth from more than 22,000 miles above Earth’s equator, paving the way for future low-cost, commercially enabled Earth observations.

It will be observing changes in concentrations of three key carbon gases – carbon dioxide, carbon monoxide and methane– from day to day and year to year. This will help researchers make a major leap forward in better understanding the carbon cycle.

GeoCarb also will be measuring solar-induced-fluorescence throughout the Americas, a direct indicator of plant health and vegetation stress.

GeoCarb is a university-led mission, funded by NASA.

NASA Moves Ahead with GeoCarb Mission, Schedules Major Milestone

GeoCarb has scheduled a major mission milestone for Tuesday, May 21, 2019. Formally known as Key Decision Point-C (KDP-C), the review will assess mission-readiness to move into the build phase of the project.

OU Clears Latest NASA Design Review for Geostationary Observatory

The GeoCarb science instrument has passed its Preliminary Design Review (PDR), the latest in a series of NASA milestone reviews. Developed in partnership with Lockheed Martin, the instrument will be mounted on a commercial communications satellite and launched into geostationary orbit at more than 22,000 miles above Earth’s equator.
