Thales Alenia Space Launches MicroCarb

MicroCarb is a joint mission between the UK Space Agency and French Space Agency, Centre National d’Études Spatiales (CNES), serving as the prime contractor. The mission is co-financed by these two agencies, as well as by the European Commission and the French government within the framework of the Investments for the Future Program (PIA), managed by the National Research Agency (ANR). The satellite is designed to precisely map atmospheric carbon dioxide (CO₂), capturing detailed data on emissions from human activities as well as absorption by natural sinks such as oceans and forests.

The satellite is built on the CNES Myriade platform. Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), completed the assembly, integration, and testing of the satellite platform at RAL Space in Harwell, UK, and was responsible for launch preparations. Airbus Defence and Space provided the instrument payload, the infrared spectrometer.

MicroCarb will operate in low Earth orbit, at an altitude of 650 km, and serves as a precursor to the European Union’s Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission – a constellation of three satellites, with payloads supplied by Thales Alenia Space, which will deliver precise measurements for human-induced atmospheric carbon dioxide and methane. MicroCarb complements the CO2M mission by providing early observations and valuable data, enhancing our capability for CO₂ and methane monitoring to inform climate policy makers.

Additionally, a special city-scanning mode will enable the mapping of CO₂ distribution within urban areas, which are responsible for the majority of global emissions.
