“We are aware of the situation and tracking it closely,” a spokesperson for ICEYE’s U.S.-based division told TWZ. That terse line accompanied a set of orbital-tracking claims that, if accurate, describe an unusually intimate and potentially hazardous rendezvous in low Earth orbit: a Russian satellite, Kosmos 2612, maneuvering to shadow a U.S.-registered commercial radar-imaging craft, ICEYE X36, at ranges measured in meters rather than kilometers.
The encounter: conflicting measurements, the same conclusion
Publicly available trackers on satellitemap.space and orbitalradar.com indicated that Kosmos 2612 passed within approximately 85 feet (26 meters) of ICEYE X36 during an especially close encounter “at approximately 16:07 UTC today,” the TWZ story reports. LeoLabs, which told TWZ it could not “confirm or contradict what other data sources have stated publicly,” put its own high-confidence assessment at roughly 500 meters (1,640 feet). Independent analysts who posted and analyzed two-line elements (TLEs) reported Kosmos 2612 executing a maneuver on Oct. 16 that put it into stationkeeping with ICEYE X36 at distances variously described as under 5 km, within 1–2 km, or potentially coming within meters.
Kosmos 2612 in the context of a six-satellite deployment
Kosmos 2612 was one of six satellites (Cosmos 2609 through Cosmos 2614) launched on April 17 via a single Soyuz-2.1b rocket. Their exact purpose is unconfirmed, but they “appear to be so-called inspector types capable of rendezvousing and maneuvering close to other objects in space,” the TWZ piece states. Beginning Sept. 30, Kosmos 2612 executed a series of maneuvers that brought it into near-coplanar alignment with ICEYE X36 and synchronized orbital period and altitude. LeoLabs’ analysis described a controlled approach, loitering in close proximity, additional small maneuvers, and then a controlled departure; subsequent observations indicate the spacecraft are now “strongly diverging” and that the close-proximity activity “had ended.”

See what we buildWhy ICEYE X36 drew attention
ICEYE X36 is a synthetic aperture radar (SAR) satellite launched in 2024. SAR can image day or night and through obscurants such as clouds or heavy smoke. Although ICEYE was founded in Finland, ICEYE X36 is U.S.-registered and, according to public reporting cited in TWZ, “might be Ukrainian owned/leased now.” Ukrainian authorities have used ICEYE imagery for years, including for targeting, and the Main Directorate of Intelligence of Ukraine (GUR) previously released an ICEYE SAR image of the Kerch Bridge. ICEYE’s U.S. division told TWZ that its “constellation architecture is designed for continuity and resilience,” and Reuters reporting quoted ICEYE CEO Rafal Modrzewski saying the company had moved its satellite, prompting further Russian manoeuvres.
Analysts and trackers: an unprecedented uncooperative RPO
Multiple analysts described the episode as a sophisticated and atypical rendezvous and proximity operation (RPO). Clayton Swope of the Center for Strategic and International Studies noted that Kosmos 2612 “executed a series of new maneuvers” to place it nearly at the same altitude as ICEYE X36. Dr. Marco Langbroek tracked the satellite alignment and wrote that KOSMOS 2612 “closed from hundreds of kilometers away to extreme proximity” and then maneuvered around ICEYE X36. Jonathan McDowell called this “the first LEO rendezvous of two active satellites where the owner of one of the sats did not give approval,” while Adam Marsh of LeoLabs called it “the most advanced and potentially dangerous uncooperative RPO we’ve observed.” LeoLabs highlighted that the actions “require planning, maneuverability, precise navigation, and significant fuel,” and may indicate onboard sensors capable of measuring relative position.
What this means for the U.S., ICEYE, and Ukraine
- The U.S. (policymakers and military): TWZ cites prior U.S. statements that American assets are routinely targeted by “reversible attacks” and that U.S. officials have disclosed unspecified on-orbit defensive weapons and pursued on-orbit refueling. The proximity demonstrated by Kosmos 2612 underscores the operational problem of uncooperative RPOs complicating attribution and escalating the need for defensive planning.
- ICEYE and commercial imagery providers: ICEYE affirmed tracking the situation and pointed to constellation resilience. Still, the report highlights that harassment in orbit can force satellites to expend finite fuel reserves, degrade mission life, and impair collection over intended areas—practical risks for commercial operators.
- Ukraine: TWZ notes Ukrainian authorities have used ICEYE imagery for targeting and that the satellite “might be Ukrainian owned/leased.” Close shadowing of such an asset can disrupt collection and raise the stakes for actors relying on commercial SAR imagery.
Deliberate, controlled shadowing of a commercial radar satellite at very close range is not merely a technical curiosity. According to the tracking firms and analysts cited by TWZ, the activity displayed capabilities—planned maneuvers, loitering, stationkeeping—that could support inspection, intelligence collection, coercive signaling, interference, or preparation for counterspace operations. Attribution would be difficult if there were no lasting damage, and the incident aligns with a pattern of inspector-type satellites Russia has flown before. For now, Kosmos 2612’s recent behavior appears to have ended; whether it will be a template for future uncooperative rendezvous remains a central and unresolved question.
