The Copernicus Sentinel-1D satellite has joined the Sentinel-1 mission in orbit. Launch took place on 4 November 2025 at 22:02 CET (18:02 local time) on board an Ariane 6 launcher from Europe’s Spaceport in French Guiana.

The Sentinel-1 mission delivers high-resolution radar images of Earth’s surface, performing in all weathers, day-and-night. This service is used by disaster response teams, environmental agencies, maritime authorities and climate scientists, who depend on frequent updates of critical data.

Sentinel-1D will work in tandem with Sentinel-1C, flying in the same orbit but 180° apart, to optimise global coverage and data delivery. Both satellites have

Researchers at the University of Western Australia, along with colleagues from the University of Bristol, the Geological Survey of Western Australia, and Curtin University, examined feldspar crystals from anorthosite rocks found in the Murchison region of Western Australia. These rocks, dated at 3.7 billion years old, are confirmed to be the oldest on the Australian continent and among the earli
