ESALaunch of FLEX and Sentinel-3C on Vega-C 🚀  Two missions just launched on one rocket, both headed up to help us look after our planet. Our FLEX mission and the Copernicus Sentinel-3C satellite lifted off together aboard a Vega-C rocket from Europe's Spaceport in French Guiana on 15 September 2026 at 03:21 CEST.  FLEX will watch plants glow as they photosynthesise. That faint light tells us how healthy a plant is, and when it's under stress, long before we'd spot any change by eye.  Sentinel-3C joins the Sentinel-3 family - operated by @EUMETSAT on behalf of the European Commission - keeping watch over our oceans, land, ice, and atmosphere. Its data feeds straight into Copernicus services, helping scientists track how our planet is changing.  📹 ESA/@CNES/Avio  #ESA #Launch #Vega-C
