NASA’s Orbiting Carbon Observatory-3 (OCO-3) launched to the International Space Station in May 2019. The space instrument will investigate carbon dioxide distribution on Earth related to the global carbon cycle, adding to the OCO-2 record. OCO-3 also has a new measurement mode that will be used to sample urban areas to quantify fossil fuel emissions. The OCO-3 project is managed by NASA’S Jet Propulsion Laboratory in Southern California. SDL has a long history with OCO missions and designed, manufactured, and tested the cryogenic subsystem for three focal plane assemblies and performed thermal design and analysis for the original OCO mission. For OCO-2 and OCO-3, SDL provided a build-to-print copy of the cryogenic subsystem.
