ESA’s FLEX satellite and the Copernicus Sentinel-3C satellite are being readied for encapsulated in a Vega-C fairing at Europe’s Spaceport in French Guiana. The arrangement of the two satellites inside the fairing is carefully designed for their separate deployment. The two satellites are fitted inside Vega-C’s fairing with a secondary payload adapter called Vespa, where FLEX is positioned below and Sentinel-3C above so that Sentinel-3C can be deployed first. The photo shows Sentinel-3C fixed to the top of the adapter.
