Close-orbiting Russian satellites sharpen concern over commercial constellations.

Germany's space commander, Major General Michael Traut, told Reuters that Russian military satellites manoeuvring near a Western commercial spacecraft showed capabilities that could threaten large constellations. The US Space Force said four Cosmos satellites moved close to a radar-imaging satellite in May, and ICEYE confirmed that one of its spacecraft was involved.

Russia has not disclosed the Cosmos satellites' capabilities, and their intent remains uncertain. Traut said disruption could occur without a direct attack, while ICEYE's chief executive said the episode demonstrated the need for stronger orbital monitoring and protection as militaries rely more heavily on commercial networks.
