Kosmos 2612 Closes In on ICEYE-X36 in Low Earth Orbit
A Russian military satellite drifted within a few kilometers of a Finnish commercial radar spacecraft without permission. The maneuver marks what analysts believe is the first instance of an unauthorized orbital approach in low Earth orbit.
The American tracking company LeoLabs stated that the Russian spacecraft Kosmos 2612 shrank the distance to the ICEYE-X36 satellite from 350 kilometers to under 5 kilometers in a single day between October 15 and October 16. Dutch satellite tracker Marco Langbroek calculated that trajectory shifts on September 30 and October 12, 15, and 16 were designed to synchronize altitude, eccentricity, and orbital period with the target. Those calculations indicate the two craft may have closed to within a few hundred meters of each other early on October 18.
Uncharted Orbital Territory
Rendezvous maneuvers between spacecraft occur routinely, but astrophysicist Jonathan McDowell pointed out that this event stands out as the first time a spacecraft has approached another without consent. Iceye operates the world’s largest constellation of commercial radar satellites. Unlike traditional optical spacecraft equipped with standard cameras, these units capture imagery using radar signals that penetrate clouds, smoke, and fog while operating in total darkness.
While Iceye maintains headquarters in Finland, the specific X36 satellite involved is registered in the American space registry rather than the Finnish one. Imagery captured by the Iceye constellation feeds intelligence operations for Ukraine. Five additional Russian military satellites shifted into nearly identical orbital planes as an Iceye satellite back in May. Iceye has not issued a public statement regarding the October approach.
Monitoring the Next Orbital Adjustments
LeoLabs noted that while the intent behind the maneuver remains unclear, the behavior warrants ongoing surveillance. Independent tracking data shows Kosmos 2612 moving away from its close proximity to the Finnish-built radar satellite after maintaining position through the mid-October weekend.
