MicroCarb is a CNES atmospheric CO2 mapping mission for global source and sink monitoring.[1] CNES operates the mission, with partners including CNRS, CEA, Meteo France, universities, the European Union / ESA, UKSA, and SCGI.[1] The satellite launched by Vega C on 2025-07-26 at 02:03 UTC and operates in a circular sun-synchronous orbit at 650 km.[1][2] MicroCarb is built on a CNES Myriade-derived platform with a 180 kg satellite mass and a five-year mission duration.[3] Its payload set includes a passive infrared spectrometer and a cloud-detection imager.[3] The spectrometer covers 758.3-768.8 nm, 1264-1282.2 nm, 1596.7-1618.9 nm, and 2023-2051 nm bands, with 1 ppm measurement precision and a 25-day revisit.[3][1]
