A Russian satellite, Kosmos-2612, approached ICEYE-X36, a radar-imaging spacecraft whose data supports Ukraine, on October 18. An astronomer estimated the closest separation at between 26 and 470 meters, though measurement limits prevent a precise figure. Russia has described inspector satellites as a deterrent, while the purpose of this maneuver has not been independently confirmed.
Russian satellite Kosmos-2612 approached ICEYE-X36, a radar-imaging spacecraft whose data is used by Ukraine’s military, to an estimated 26 to 470 meters on October 18, according to observations cited by Meduza. The encounter, which followed several days of orbital maneuvers, was described by an independent researcher as unusually close for low Earth orbit; the exact distance remains uncertain because of measurement limits.
Observational astronomer Marco Langbroek estimated that the spacecraft came closest at about 1:35 a.m. GMT. The possible distance range is wide, and the available measurements do not support a more precise figure. Independent researcher Bart Hendrickx told Meduza he knew of no previous encounter at such close range in low Earth orbit; he said earlier encounters he was aware of involved separations of at least several dozen kilometers.
The approach followed maneuvers that began four days earlier. Meduza reported that Russian satellites had approached the same ICEYE spacecraft before: four Kosmos satellites moved near it in the spring. The report also describes earlier February maneuvers by Russian Luch satellites near telecommunications spacecraft operated by Intelsat and Eutelsat. It says Kosmos-2612 and other satellites in the group were launched together from Plesetsk on April 16.
ICEYE is a Finnish-American company that provides Ukraine’s armed forces with access to satellite images of Russian military sites, including airfields, naval ports and oil refineries, according to the report. The source does not establish that Kosmos-2612 physically interfered with ICEYE-X36, damaged it or forced it to maneuver during this specific encounter.
Risks to Commercial Spacecraft
A close approach can carry operational risks even without a collision. A spacecraft operator may have to monitor the other object, assess whether it will move again and decide whether an evasive maneuver is warranted. Such actions can consume fuel and complicate a satellite’s planned work. In this case, however, the source material does not confirm that ICEYE-X36 took evasive action or lost fuel.
The episode matters because commercial satellites support military activity as well as civilian services. ICEYE imagery can help Ukraine observe locations on the ground, while Starlink communications are important to Ukrainian military command and communications, the report says. Treating commercial spacecraft as part of a conflict could increase pressure on companies whose services have military value, while raising the possibility of miscalculation in orbit.

A Pattern of Orbital Approaches
Russia has previously acknowledged launching inspector satellites, but its military said their purpose was to monitor Russian spacecraft. The maneuvers described in the report have drawn attention because the satellites approached spacecraft operated by companies that provide services relevant to Ukraine and other Western users.
Russian military expert and retired colonel Yuri Knutov, writing in the government newspaper Rossiyskaya Gazeta, characterized inspector satellites as a deterrent and argued that commercial companies supporting intelligence collection against Russia should expect scrutiny in orbit. He also described ICEYE and Starlink as part of NATO’s intelligence apparatus. Those are claims made by a Russian commentator, not independently established findings in the report.
Inspector satellites are not unique to Russia. The source says the United States and China also develop spacecraft capable of approaching other satellites. Such operations may be intended to inspect a spacecraft, diagnose a problem or intercept transmissions; depending on their capabilities and intent, close approaches can also raise concern about interference or damage. The report does not provide details about the programs of other countries beyond this broad context.
“I knew of no previous encounter at such close range in low Earth orbit.”

Distance and Intent Remain Unclear
The closest distance is an estimate, not a precise measurement: Langbroek’s range runs from 26 to 470 meters. The report does not establish whether the maneuver was intended to inspect ICEYE-X36, gather information, signal a warning or cause the satellite to change course. Russia’s account of the purpose of this specific approach is not included.
It is also unclear whether ICEYE-X36 maneuvered in response, how much fuel any action may have used, or whether the spacecraft’s operations were affected. The report cites Knutov’s theory that close approaches could compel a target to evade and consume fuel, but does not present evidence that this occurred in this encounter. No collision, damage or direct interference is reported.
Operators Track Further Maneuvers
The immediate next step is continued observation of the satellites’ orbits and any further approaches. The source material does not identify a planned investigation, official diplomatic response or public statement from ICEYE about this episode. It is also unclear whether Russia will repeat similar maneuvers near ICEYE spacecraft or other commercial satellites.
Further tracking could help clarify whether Kosmos-2612 changes course again and whether ICEYE-X36 alters its orbit. Any later claims about a forced inspection, fuel depletion or operational impact would need confirmation from the operators or independent orbital measurements; for now, the reported close approach and its uncertain distance are the clearest established details.
Key Questions
How close did Kosmos-2612 get to ICEYE-X36?
Observational astronomer Marco Langbroek estimated a closest separation of 26 to 470 meters at about 1:35 a.m. GMT on October 18. Measurement limits prevent a more precise estimate.
What does ICEYE-X36 do?
It is a radar-imaging satellite operated by Finnish-American company ICEYE. According to the report, Ukraine’s armed forces use access to ICEYE imagery of Russian military sites.
Did Russia damage or disable the ICEYE satellite?
The report does not say that ICEYE-X36 was damaged or disabled. It also does not confirm that the satellite maneuvered to avoid Kosmos-2612 or lost fuel.
Has Russia explained why Kosmos-2612 approached it?
The source does not give an official Russian explanation for this specific maneuver. Russian military expert Yuri Knutov described inspector satellites as a deterrent and the approach as a warning, but that is his stated interpretation.
Do other countries operate inspector satellites?
Yes. The report says the United States and China also have programs to develop inspector satellites, which can approach other spacecraft for purposes such as inspection or diagnosing problems.
