NASA's orbiting Carbon Observatory-3 gets first data

NASA's Orbiting Carbon Observatory-3 (OCO-3), the agency's newest carbon dioxide-measuring mission to launch into space, has seen the light. From its perch on the International Space Station, OCO-3 captured its first glimpses of sunlight reflected by Earth's surface on June 25, 2019. Just weeks later, the OCO-3 team was able to make its first determinations of carbon dioxide and solar-induced fluorescence—the "glow" that plants emit from photosynthesis, a process that includes the capture of carbon from the atmosphere.
