ANSER is a distributed nanosatellite Earth-observation mission from INTA for inland-water and reservoir monitoring.[1][2] It launched on 2023-10-09 UTC on Arianespace Vega flight VV23.[3] The mission uses a 3U CubeSat-class ANSER nanosatellite bus and the CINCLUS red and near-infrared photometer payload.[1][2] CINCLUS is described with five narrow red/NIR bands, a 50 km swath, 50 m ground sampling, and a coverage goal of less than 30 days over the Iberian Peninsula.[1][2] The mission focus is targeted water-resource observation from formation-flying nanosatellites.[1]
