The Sentinel-1 mission – which provides radar vision for the Copernicus Earth observation programme – has a new addition to its family of satellites, with the arrival in orbit of Sentinel-1D, the last of the groundbreaking first generation. The launch took place at 22:02 CET (18:02 local time), on Tuesday, 4 November, on board an Ariane 6 launcher from Europe’s Spaceport in French Guiana.

Europe needs to synchronise space for defence initiatives, align competencies, avoid duplication & pool resources. We remain too fragmented to guarantee Europe with genuine, comprehensive and autonomous space resilience. We have an opportunity to change that, and we must.

Building on its strong expertise in security and resilience, Poland is uniquely positioned to play a leading role in ESA’s European Resilience from Space initiative at ESA's Ministerial Council, a timely opportunity to reaffirm its long-term strategic commitment to European space leadership.

Imagine a Europe without ESA: the Universe would dimmer and less explored, we would celebrate fewer native astronauts or space scientists, and our telecommunications, navigation and weather forecasting would be dependent on foreign powers.
