A Russian satellite, Kosmos 2612, may have passed within approximately 85 feet (26 meters) of a U.S.-registered satellite belonging to commercial imagery provider ICEYE. This would be an extraordinarily close and potentially dangerous pass-by for two objects in space traveling at thousands of miles per hour. For weeks beforehand, ICEYE-X36, which would be of special interest to Russia, had already found itself in increasingly close orbital alignment with its pursuer. The two satellites now look to be drifting further and further apart, but the episode has been a clear sign of what is to come as the potential for conflict in space only continues to grow.
Publicly available space tracking data from the satellitemap.space and orbitalradar.com websites show that Kosmos 2612 (also written sometimes Cosmos 2612 and abbreviated K2612) and ICEYE X36 had their especially close encounter at approximately 16:07 UTC today. Private space services company LeoLabs also told TWZ today that it could not “confirm or contradict what other data sources have stated publicly,” but that it has “high-confidence that the objects came within approximately [emphasis in the original] 500 meters [1,640 feet] of each other.” Kosmos 2612 had been making progressively closer passes by ICEYE X36 in recent days.
“COSMOS 2612 closed from hundreds of kilometers away to extreme proximity to ICEYE-X36. It then maneuvered around ICEYE-X36, remained nearby for an extended period, and then began moving away,” LeoLabs also stated in a report assessing the situation, which was updated today and provided to TWZ. “The latest observations show the spacecraft strongly diverging and confirm that the close-proximity activity had ended.”
LeoLabs’ broader assessment here is supported by data from other publicly available sources, as seen below.
Additional context
None of the distances stated earlier may seem especially close, let alone worrisome, by terrestrial standards. However, this is absolutely abnormal for operations in space that are not being directly coordinated by the parties involved. As a point of reference, in 2020, another Russian satellite, Kosmos 2542, came within 150 to 300 kilometers (93 to 186 miles) of USA 245, a KH-11 spy satellite, and became a major international news story.
“We are aware of the situation and tracking it closely,” a spokesperson for ICEYE’s U.S.-based division told TWZ this morning. “Our constellation architecture is designed for continuity and resilience.”
ICEYE was founded in Finland, but now has offices globally. The company specializes in providing imagery via synthetic aperture radar (SAR) from satellites like ICEYE X36, which was launched in 2024.
SAR has the benefit of being able to capture images day or night, and regardless of bad weather or other obscurants like heavy smoke. There are trade-offs in terms of the kinds of details typically visible via SAR compared to what is seen in visual spectrum imagery. Ukrainian authorities have been utilizing ICEYE imagery for years now, including for targeting purposes, as part of the ongoing conflict with Russia. There have been reports in the past that ICEYE X36 has been operating more directly under the control of the Ukrainian government, but this has not been confirmed.
Kosmos 2612 is one of six satellites (Cosmos 2609 through Cosmos 2614) the Russian military launched via a single Soyuz-2.1b rocket on April 17. The exact purpose and configuration of these satellites are unconfirmed. However, they appear to be so-called inspector types capable of rendezvousing and maneuvering close to other objects in space. We will come back to this later on.
What is clear is that Kosmos 2612 has spent the past three weeks deliberately maneuvering to extremely closely shadow ICEYE X36.
“Over two weeks beginning on September 30, 2026, Cosmos 2612 executed a series of new maneuvers that brought it back into coplanar alignment and placed it at nearly the same altitude as the commercial satellite,” Clayton Swope, Deputy Director of the Aerospace Security Project and Senior Fellow at the Center for Strategic and International Studies (CSIS) think tank in Washington, D.C., along with Research Assistant Chantal Li, wrote in an analysis of the situation just last Thursday.
“According to current orbital elements, the Russian #KOSMOS 2612 satellite is now within 1-2 km [0.6 miles to 1.2 miles] of #ICEYE-X36,” Dr. Marco Langbroek, currently a lecturer on Space Situational Awareness at the Faculty of Aerospace Engineering of Delft Technical University in the Netherlands, wrote in a thread on X on Saturday. “Based on current elements, it might come within meters of the latter within a few hours from now. This is an #RPO [rendezvous and proximity operation] without consent.”
“New TLEs [two-line elements] show that K2612 made a manuever [sic] on Oct 16 and is now stationkeeping within 5 km [3.1 miles] or less of ICEYE X36,” Jonathan McDowell, an astrophysicist and astronomer, who previously worked for the Harvard-Smithsonian Center for Astrophysics and has long been tracking objects of interest in orbit, also wrote in a series of posts on X on Saturday. “To my knowledge this is the first LEO [low Earth orbit] rendezvous of two active satellites where the owner of one of the sats did not give approval.”
McDowell later clarified that “close passes” of objects in orbit had certainly occurred previously, “but not I think rendezvous [sic] (matching velocity vector).”
“This is the most advanced and potentially dangerous uncooperative RPO we’ve observed,” Adam Marsh, LeoLabs vice president for technical solutions, separately told Breaking Defense.
Unprecedented orbital maneuvering
As underscored by the previous interaction of Kosmos 2542 and USA 245, close shadowing of satellites in orbit is certainly nothing new. The U.S. government, as well as Russia and others, have been observed engaging in this kind of activity in the past. At the same time, just how close Kosmos 2612 got to ICEYE X36, and how long they spent in close alignment, are, at the very least, highly unusual.
“It’s important to note that ‘red’ on ‘blue’ engagements, such as this, are relatively uncommon in Low Earth Orbit (LEO),” LeoLabs’ report points out. At the same time, “this was not a routine conjunction or ‘fly by.’ The sequence included a controlled approach, changes in relative position, close-proximity loitering, additional small maneuvers, and a controlled departure. The behavior is consistent with sophisticated rendezvous and proximity operations (RPO).”
On top of this, there are other signs that what just happened between Kosmos 2612 and ICEYE X36 may follow a Russian playbook of sorts that could also be used in a prelude to an on-orbit anti-satellite attack.
Within weeks of their launch in April, Kosmos 2610, 2611, 2612, 2613, and 2614 had all moved orbital planes shared by multiple ICEYE satellites. Three of them subsequently made close passes by ICEYE X36, specifically, but none of them initially kept station with it. ICEYE CEO Rafal Modrzewski did say “the company later moved its satellite, prompting further Russian manoeuvres [sic],” according to a story Reuters published last week.
To take a step even further back, before Kosmos 2542 was caught shadowing USA 245 in 2020, there were reports that the U.S. spy satellite had shifted its orbit. This was possibly prompted by the movements of another Russian ‘inspector,’ Kosmos 2543. This does not appear to have ever been confirmed.
While in space, Kosmos 2542 had deployed Kosmos 2543 in November 2019. Then, on July 23, 2020, the U.S. military said that it had detected Kosmos 2543 itself launching a smaller object in what it described as a test of a space-based anti-satellite weapon. In a subsequent interview with Time, then-Chief of Space Operations Gen. John “Jay” Raymond, U.S. Space Force’s top uniformed officer, disclosed that American forces had first observed Russian “nesting doll” satellites – a reference to traditional Russian matryoshka dolls – similarly demonstrating the “characteristics of a weapon system” in 2017.
U.S. officials have been warning for years that Russia’s growing array of inspector-type satellites, ostensibly designed to examine other assets the country has in orbit if they break down or otherwise malfunction, are inherently dual-purpose in nature. Beyond launching projectiles, a host of other modes of attack, kinetic and non-kinetic, are enabled by the underlying ability of a spacecraft to maneuver very close to other objects in orbit and hold that position. This includes the use of grappling arms to cause damage or just tow a satellite out of orbit, spraying aerosols to harm or impair optics and solar panels, and electronic warfare jamming. A satellite could turn out to be the weapon itself, becoming a kinetic interceptor that smashes into its target on command.
One satellite shadowing another closely in orbit allows various kinds of intelligence gathering, as well. Collection of imagery and signal emissions can offer valuable details about a target’s capabilities and vulnerabilities, as s well as how it is being used in a particular context.
“As observed by LeoLabs Global Radar Network and analyzed by our team, COSMOS 2612 demonstrated a sequence of capabilities that could be used to inspect, characterize, shadow, or potentially interfere with another spacecraft,” according to LeoLabs’ report. “These actions require planning, maneuverability, precise navigation, and significant fuel. They may also indicate the use of onboard sensors capable of measuring the relative position of another spacecraft.”
What has just transpired between Kosmos 2612 and ICEYE X36 highlights how just a viable threat of attack can be disruptive in its own right. Simply forcing an imagery-gathering satellite out of position could prevent it from collecting over an intended area, or at least doing so in the most effective manner.
Furthermore, satellites only have a limited amount of fuel with which to maneuver in any way after reaching orbit. Harassment in space that forces them to burn off that finite resource at a higher-than-expected rate could reduce their total operational life expectancy, as well as further limit their effectiveness and make them more vulnerable to attacks or accidents. Debris in space is a steadily growing hazard that satellites increasingly need to dodge.

The United States, among others, has been actively pursuing on-orbit refueling capabilities to help address these issues. Last month, American officials also made the bombshell admission that there are unspecified U.S. weapon systems in orbit now, ostensibly for defensive purposes amid growing threats from Russia, as well as China. Both of those countries, among others, have been actively developing and fielding various anti-satellite capabilities inside and out of the Earth’s atmosphere.
“We can only speculate about the operation’s goal, but it could have been anything from simply intimidation to outright destruction or sabotage of a U.S.-registered satellite,” CSIS’ Clayton Swope told TWZ directly today in light of the new developments regarding Kosmos 2612 and ICEYE X36. “Perhaps the operation is on hold. There are, however, several other satellites that shadowed ICEYE X36 back in May that could be brought in[to] action too.”
Attribution and broader ramifications
It is important to point out that space, as a domain, inherently creates complications when it comes to attributing any form of attack, should one occur. Satellites do suffer mishaps, sometimes with catastrophic results, the causes of which are not always clear.
Just in January, a Russian inspector satellite launched in 2014 appeared to break up unexpectedly. Sometime around the end of July, the Chinese reconnaissance satellite Yaogan 50-02, which had only been launched some four months earlier, also broke up in orbit. On Sept. 13, a similar fate befell the U.S. Cold War-era Farrah III spy satellite, also known as USA 32. At the time of writing, no firm evidence has emerged to indicate any of these incidents were the result of hostile action rather than accidents of some kind.
“While the intention behind COSMOS 2612’s behavior remains uncertain, the deliberate nature of the activity, the fuel required to conduct this activity, and the proximity to a Western commercial imaging satellite make the event strategically important,” LeoLab’s report notes. “This event, and the capabilities demonstrated, do not establish hostile intent. It does, however, demonstrate capabilities that could support intelligence collection, on-orbit inspection, coercive signaling, interference, or preparation for future counterspace operations.”
It is very possible, if not highly probable, that Kosmos 2612’s recent activities will be indicative of a trend going forward. Aggressive and potentially dangerous maneuvering by armed forces in close proximity to each other is not uncommon within the atmosphere, especially in the air and at sea. Extending a variation on those tactics into the space domain would make sense, especially given the central role that capabilities in orbit increasingly play in modern military operations globally. Those roles extend to early warning, general intelligence gathering, weapons guidance, near-real-time communications, and beyond.
American officials have already said in the past that American assets in space are routinely the target of “reversible attacks,” meaning ones that do not cause permanent damage. That also speaks to the difficulty of attribution if there is no lasting effect or impact to draw attention to.
The U.S. government’s long-time monopoly on the space domain has also been steadily eroding in recent years, especially in light of China’s massive expansion of its intelligence-gathering and other satellite constellations. The scale and scope of what commercial satellite imagery and other space services providers, like ICEYE, offer today have led to a further democratization of space-based capabilities to countries like Ukraine that do not possess significant, if any, constellations of their own.
All of this, in turn, has increasingly driven the U.S. military, specifically, to plan for more proactive operations and potential direct conflict in orbit to ensure it retains its edge going forward. The aforementioned disclosure of U.S. on-orbit weapons is indicative of those developments and an accompanying shift in U.S. policy to be more open about counter-space capabilities.
More details may yet emerge about Kosmos 2612 and its recent rendezvous in orbit with ICEYE X36, but it already points to how space has become an increasingly likely potential zone for direct conflict going forward.
