26 July 2025 year Fr. 02:03 (UTC) from the Kuru Cosmodrome, French Guiana using a launch vehicle «Vega-C» four French optical surveillance satellites were launched «CO3D» and one scientific spacecraft «MicroCarb».
«CO3D (3D Optical Constellation)» – it is a satellite group of four optical earth observation satellites, developed by CNES. The spacecraft will provide high-resolution stereo images 50 cm. The resulting data will be transmitted to the Airbus center to create an advanced 3D map of the Earth's landmass. CO3D satellites weigh approx 300 kg will join the fleet of optical and radar satellites of Airbus, strengthening the company's ability to meet the growing demand for quality images. Together with the four Pléiades-Neo satellites, the CO3D constellation will provide an unparalleled refresh rate of very high resolution images. In the future, the constellation can be expanded to twenty satellites.
«MicroCarb» – cis a microsatellite, created by CNES (France) together with the UK Space Agency and the EU to monitor emissions and absorption of the greenhouse gas CO₂ at the global level. The satellite weighs about 180–190 kg, built on the Myriade platform, equipped with a dispersion infrared spectrometer, able with precision 1 ppm to measure CO₂ concentration and build two-dimensional maps with a resolution of 4.5×9 km, and in "city scanning" mode - up to 2×2 km. The satellite will work close 5 years, providing data to the climate science community, researchers and politicians. The goal of the project is to fill the gaps in observations, improve understanding of the carbon cycle and support the implementation of climate agreements, including Paris.
