Sentinel-1C was launched into orbit on 5 December, lifting off aboard Vega-C at 22:20 CET (18:20 local time). The launch proceeded smoothly, with the rocket reaching space in eight minutes and dropping off Sentinel-1C at approximately 00:04 CET.

The launcher’s mission, called VV25, is a return-to-flight for Vega-C – Europe’s lightweight, high-performance rocket – marking the restart of routine commercial operations for the new launcher. At 00:12 CET, ESA established communication with the satellite confirming that it was safely in orbit.

ESA’s Director General Josef Aschbacher said, “One moment combined two great European achievements today: the third launch of a Sentinel-1 satellite and the third launch of Vega-C, marking a triumphant return to form for both flagship European projects. It was exciting and touching to see the mix of the European launcher and Copernicus community and teams rooting each other on in true Team Europe form.

"With the insertion of Sentinel-1C into orbit, ESA continues a legacy of steadfast Sentinels protecting the Earth and exemplifies why Europe needs secured flights: because what we send to space provides benefits to Earth, and it all starts with a launch.”

ESA’s Director of Space Transportation Toni Tolker-Nielsen said, “Today’s launch marks a crucial step forward, reaffirming European independent access to space. With Vega-C back in flight and the inaugural launch of Ariane 6 in July, we are in a great place going forward and I salute all the hard-working teams all over Europe and its spaceport who have worked tirelessly to achieve this success.”

ESA’s Director of Earth Observation Programmes Simonetta Cheli added, “We are thrilled to celebrate the launch of Sentinel-1C, an example of the enduring partnership between ESA and the European Commission. The mission plays a crucial role in addressing global challenges like climate change and disaster response, while ensuring the continuity of vital radar data for monitoring Earth’s land, oceans and ice.

“With Sentinel-1C successfully in orbit and Vega-C back in flight, Europe continues to demonstrate its leadership in space, delivering tangible benefits for Earth through cutting-edge technology and collaboration.”
