A Russian military satellite called Kosmos 2612 maneuvered to within less than a mile of a commercial radar-imaging satellite that supplies intelligence to Ukraine, a close pass that analysts say was deliberate and unusually sustained. The target, ICEYE-X36, is registered as a United States satellite and owned by ICEYE US, the American subsidiary of the Finnish company ICEYE. No damage to the satellite has been reported.
The approach unfolded over several weeks, according to The New York Times, which reported that Kosmos 2612 began a series of maneuvers toward ICEYE-X36 on September 30. Tracking firm LeoLabs said the behavior was consistent with what is known as rendezvous and proximity operations, as detailed by CNN. The firm said such maneuvers could be used to inspect, characterize, shadow or potentially interfere with another spacecraft, but cautioned that the available evidence does not establish hostile intent.
Estimates of exactly how close the two satellites came vary widely across reporting. LeoLabs put the closest approach at roughly 500 meters while cautioning that the precise separation remained uncertain, per the same CNN report. The Washington Times separately cited public tracking data estimating a miss distance of about 85 feet, while orbital-tracking site orbitalradar.com had predicted a closest approach of 26 meters for October 19 — a figure that was not later re-confirmed.
A Radar Satellite With Military Reach
ICEYE-X36 relies on synthetic-aperture radar, a technology that produces high-resolution imagery day or night and regardless of weather, according to CNN. CNN and The New York Times report that ICEYE provides imagery and data support to Ukraine, helping explain why a Russian military satellite's interest in this particular craft has drawn such scrutiny.
In response to the episode, ICEYE said its constellation architecture is designed for continuity and resilience, according to CNN. There were no reports of physical damage to ICEYE-X36 as Kosmos 2612 began retreating, Ars Technica noted. Even so, astronomer Jonathan McDowell told the outlet that the incident may represent the first known low-Earth-orbit rendezvous between two active satellites conducted without approval from one satellite's owner.
Months of Orbital Positioning Preceded the Close Pass
The October encounter did not come out of nowhere. CNN reported that four Russian-controlled satellites had adjusted their orbits to align with ICEYE-X36 since May, according to a June report from the Royal United Services Institute. Tracking analysis published by keeptrack.space found that five Cosmos satellites raised their orbital inclinations between May 13 and May 22, nudging them closer to ICEYE-X36's orbital plane months before the close approach.
The same keeptrack.space analysis found that Kosmos 2612 raised its own orbit by 47 kilometers in two burns on September 30 to adjust its timing relative to ICEYE-X36, then closed the gap dramatically after a maneuver on October 15 — shrinking the distance between the two craft from 350 kilometers to less than 5 kilometers by early October 16. The pattern points to a calculated, multi-month approach rather than a chance close pass.
US Officials Call the Maneuvers Threatening
American officials have framed the episode in starker terms. The United States has accused Russia of threatening actions in space, with officials describing Cosmos 2612 as a Russian military satellite that maneuvered dangerously close to a U.S. commercial satellite, The Economic Times reported. Thomas G. DiNanno said the satellite's behavior was consistent with on-orbit weapons operations in a post on X, and added that the United States will continue to secure and defend American vital national security interests in, from and to space, per the same report.
Earlier Russian Satellite Encounters
Earlier incidents illustrate the pattern. In 2020, the Russian satellite Kosmos 2542 positioned itself close to the U.S. National Reconnaissance Office satellite USA 245, remaining within 150 to 300 kilometers of it and staying in its view for nearly two weeks, as reported by The Verge. In 2015, a Russian satellite known as Luch stationed itself next to two U.S. communications satellites operated by Intelsat and stayed there for five months, the outlet reported. The U.S. military runs its own version of this activity through the Geosynchronous Space Situational Awareness Program, whose satellites approach and inspect spacecraft operated by other countries, according to the same report.
The New York Times suggested the episode indicates that commercial satellites, not just government or military assets, can now be targets in the broader space rivalry among Russia, the United States and China.
Diplomatic Backdrop
The satellite episode surfaced the same week as renewed diplomatic activity over the war in Ukraine. Special envoy Steve Witkoff held talks with Russian President Vladimir Putin in St. Petersburg on Wednesday. The meeting followed Witkoff's sit-down a day earlier with Ukrainian President Volodymyr Zelensky in Norway, which CNN described as productive.
