Today, the European Space Agency (ESA) Director of Science, Carole Mundell, ESA Director of Space Transportation, Toni Tolker-Nielsen, and Arianespace Chief Commercial Officer, Steven Rutgers, signed the launch agreement to fly ESA’s scientific mission Plato; the formal step took place at the European Space Conference in Brussels, Belgium.

Entrusted by the European Commission, ESA has signed a contract with Arianespace to secure an Ariane 6 rocket for the launch of the Sentinel-1D satellite, the fourth unit of the Copernicus Sentinel-1 mission, scheduled for the second half of this year.

ESA, Eumetsat, the European Commission and Arianespace have announced an agreement to advance the launch of the first MetOp Second Generation weather satellite, which also carries the Copernicus Sentinel-5 mission, to August 2025 aboard an Ariane 6 rocket.

In December 2024 the first Themis – Europe’s demonstrator of a reusable rocket first stage – completed a ‘full fit-check’ standing tall at ArianeGroup’s facility in Les Mureaux, France.

This step in the rocket development proves that all main elements fit together as planned, confirming the mechanical connections and interfaces from the lower to the upper parts of the rocket stage connect smoothly and as intended.

The 28-m tall model includes the main elements for Themis such as the engine bay, the fuel tanks, the flight control bay and the upper part. It is powered by the new-generation European Prometheus, an engine developed by ArianeGroup that runs on liquid methane and liquid oxygen and can vary its throttle in flight that is necessary for landing.

This fit-check was one of the key requirements and one of the final steps in Les Mureaux to conclude the development phase of Themis – designated T1H for Themis 1-engine Hop – opening the way for its transport to the Esrange Space Center in Sweden from where it will have its first flight next year. Its first flight will be a short hop, taking off and landing from the same location, organised as part of the European Commission Salto programme.

Relive the Vega-C launch, flight VV25, from various angles.

The third Copernicus Sentinel-1 satellite, Sentinel-1C, has launched aboard a Vega-C rocket, flight VV25, from Europe’s Spaceport in French Guiana. The rocket lifted off on 5 December 2024 at 22:20 CET (18:20 local time).

Sentinel-1C extends the legacy of its predecessors, delivering high-resolution radar imagery to monitor Earth’s changing environment, supporting a diverse range of applications and advance scientific research. Additionally, Sentinel-1C introduces new capabilities for detecting and monitoring maritime traffic.

The launch also marks Vega-C’s ‘return to flight’, a key step in restoring Europe’s independent access to space. Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.
