Telesat will expand its planned low Earth orbit Lightspeed network to 225 satellites, restoring the 25% of commercial capacity previously diverted to defense customers. The change increases the capacity available for commercial services while preserving the constellation’s role in supporting defense requirements.

Cailabs is introducing shared optical ground-station infrastructure, while ICEYE and Arianespace will evaluate Ariane 6 for sovereign SAR missions. Poland’s EYCORE reported first imagery from its inaugural radar satellite, and BAE Systems and the U.S. Space Force completed a critical design review for Epoch 2 missile-warning satellites planned for 2029.

German startup Isar Aerospace reached orbit with its Spectrum rocket from Andøya, Norway, deploying satellites on the vehicle’s second flight. The mission makes Isar the first commercial European company to deliver payloads to orbit from continental Europe, advancing the region’s effort to reduce reliance on American launch providers.
York Space Systems has introduced a new satellite platform intended to operate in very low Earth orbit (VLEO). The announcement adds a dedicated satellite-bus offering to the company’s portfolio for missions requiring operations in the increasingly specialized lower orbital regime.
European space executives are calling for policy changes to build a stronger and more profitable industrial base, while Airbus Defence and Space is partnering with Axelspace to broaden access to Earth-observation imagery. Separately, York Space Systems introduced a standardized smallsat platform designed for sustained very-low-Earth-orbit operations.

Russia’s Rassvet-3 constellation, positioned as a rival to Starlink, is struggling after all 16 satellites in its second batch failed to reach their intended orbit. At least three of the first 32 satellites likely suffered outright failures, leaving only 12 of 32 launched spacecraft set for long-term orbit.
Telesat and French photonics company Cailabs will assess space-to-ground optical communications for Telesat’s Lightspeed low-Earth-orbit constellation. The collaboration will examine optical ground stations to support secure government communications and data relay, potentially extending the constellation’s capabilities beyond conventional radio-frequency links.
