Sentinel-1C

Third C-band SAR satellite in ESA's Copernicus Sentinel-1 constellation, launched to restore the two-satellite radar pair following Sentinel-1B's loss in 2022. With two satellites operational again, the constellation resumed its designed six-day global repeat cycle for monitoring surface deformation, sea ice, and marine environments.

Return to flight for Vega-C following the VV22 failure in December 2022. Sentinel-1C had originally been manifested on a Soyuz rocket; ESA moved it to Vega-C after Russia suspended commercial Soyuz launches following its invasion of Ukraine.
