Vega-C mobile building rolling

A view from the launch pad with Vega-C flight VV25 ready for liftoff as the mobile building that surrounds the rocket rolls away to reveal the rocket to the skies. 

The mobile building allows Vega-C’s four stages to be assembled on the launch pad in security and offers protection from the elements. The 50-metre high structure weighs over 1000 tonnes, and a hydraulic system drives wheels on an 80-m rail track. The gantry is powered by two electric motors of some 70 kW capacity, these operate the hydraulic pumps supplying pressurised oil to six wheels. 

The third Copernicus Sentinel-1 satellite, Sentinel-1C, 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.
