LAB4S2, the Innovative Laboratory for Space Spectroscopy is an ANR funded Common Laboratory aiming to bridge the gap between high resolution spectroscopy and broad band imaging for the JWST MIRI instrument and for Earth Observation Sentinel-2 and Sentinel-3 Copernicus missions.

The ANR LabCom LAB4S2 is a key collaboration between ACRI-ST and the Institut Astrophysique Spatiale (IAS) to advance in the challenging problematic of data fusion of small field high spectral resolution data and wide field multi-band imaging of space science data. The research is applied to data from the MIRI instrument on the James Webb Space Telescope as well as, in parallel, on data acquired with the Copernicus Sentinel-2 and Sentinel-3 EO missions.
