Prior to approving the change, the EC had performed an in-depth investigation due to concerns that

297-503: The Iridium satellites , the flares are often long-lasting, with the satellites traversing much of the sky at brighter-than-average magnitudes. To replace the first COSMO-SkyMed constellation, the Italian Space Agency is developing the COSMO-SkyMed second generation constellation. The 2nd generation constellation has the same function of radar-based Earth observation with particular focus on
