🚀 Major progress ahead of launch!

Fresh images and updates for #Copernicus Sentinel-3C! The satellite - seen in the images here integrated onto the launcher and moved onto the launchpad - has passed two critical countdown milestones:

🔹 Operational readiness confirmed: On 8 September, the Rehearsal Review Board confirmed that the Sentinel-3C system is in excellent shape and teams are ready. 
🔹 Dress rehearsal complete: On 10 September, a final pre-launch simulation in Kourou tested the full countdown sequence from L-10 hours, including anomaly detection and operational communications.

Next steps: Attention turns to the Launch Readiness Review today, 11 September, ahead of launch with co-passenger FLEX on a Vega-C rocket next week! 🛰️
