COSMO-1 or COSMO-SkyMed 1 is an Italian radar imaging satellite. Launched in 2007, it was the first of four COSMO-SkyMed satellites to be placed into orbit. The spacecraft is operated by the Italian Space Agency (ASI), in conjunction with Italy's Ministry of Defence. It uses synthetic-aperture radar to produce images for civilian, commercial and military purposes.
