Watching Grass Grow from Space: NASA’s Orbiting Carbon Observatory-2 Satellite Gives Insights into Photosynthesis and Climate Change

The mission of NASA’s Orbiting Carbon Observatory-2 satellite is to improve our understanding of the factors that control global carbon dioxide levels. The satellite was designed to measure atmospheric carbon dioxide, but it can also detect a signal of plant photosynthesis — a key carbon sink. NASA scientists are working to use these two pieces of information together to disentangle natural and human influences on the carbon cycle.
