Telesat is preparing to deploy a couple of Lightspeed pathfinders in December 2026, with 96 satellites for an initial global broadband service from LEO set to launch the following year to offset mounting geostationary business declines.

The Copernicus Sentinel-1D satellite has joined the Sentinel-1 mission in orbit. Launch took place on 4 November 2025 at 22:03 CET (18:03 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

London — Warsaw Increasing tensions with Russia have prompted defense spending boosts throughout Europe that will benefit fledgling smallsat launcher companies across the continent.

From 7 to 10 October 2025, Europe and Africa took another important step toward deepening their cooperation in space. At the ESA Education Training and Learning Facility in ESEC-Galaxia, Belgium, young engineers from across both continents came together for the Space Systems Engineering Training Course, jointly supported by the European Space Agency (ESA) and the African Space Agency (AfSA).

Boston, MA (SPX) Oct 31, 2025 Marco Graffiedi, a doctoral student in nuclear science and engineering, is researching quenching processes to help cool nuclear cores, and NASA craft the next generation of space vehicles. Quenching, a powerful heat transfer mechanism, is remarkably effective at transporting heat away. But in extreme environments, like nuclear power plants and aboard spaceshi
