A Russian-made satellite called Kosmos 2612 got very close to ICEYE-X36 last week, a commercial Earth-observation satellite that may support countries like Ukraine. CNN reports it may have come within less than a mile. Orbital monitoring company LeoLabs says the behavior is consistent with rendezvous and proximity operations, meaning maneuvers designed to bring two spacecraft together.
“A rare move by a Russian-made satellite may have brought it within less than a mile of a commercial Earth-observation satellite that may be used to provide national security services to countries such as Ukraine.” states CNN.
“It’s not clear what, exactly, the Russian satellite, called Kosmos 2612 or Cosmos 2612, intended to accomplish with its close approach. But the behavior was consistent with rendezvous and proximity operations, or maneuvers carried out in orbit that are designed to bring two spacecraft together, said orbital monitoring services company LeoLabs, which tracks space junk and activity in Earth orbit, in a statement.”
It is unclear what Russia wanted to achieve. LeoLabs said “While the intent remains uncertain, the behavior warrants continued monitoring.” Astrophysicist Jonathan McDowell noted that this could be the first known case of one spacecraft approaching another without permission. This is different from docking, when two spacecraft intentionally connect, a common practice in space.
The events unfolded over several months. In May, four Russian-controlled satellites changed their orbits to align with ICEYE-X36, according to a June report by the Royal United Services Institute. On October 15, Kosmos 2612 began moving closer to ICEYE-X36, reducing the distance from 350 kilometers to less than 5 kilometers by early October 16. It stayed nearby, making small adjustments through the weekend, before starting to move away on Monday. The War Zone (TWZ) reports that Kosmos 2612 was one of six satellites launched together on April 17.
The closest point is disputed. LeoLabs says it came within roughly 500 meters during part of the event, but warns that the repeated maneuvers and awkward tracking geometry make separation estimates uncertain. Space.com reports the satellites may have been a few meters apart at one point, and TWZ’s reading of public tracking data points to about 26 meters.
The target matters. ICEYE operates about 80 radar satellites that image the Earth through clouds, day and night, and ICEYE-X36 belongs to its US subsidiary. At least some ICEYE satellites provide imagery to Ukraine, and in January the company signed a contract firming up that relationship, saying it gives Ukraine’s Ministry of Defence persistent situational awareness on tactical timelines. A Ukrainian official told Axios that Ukraine’s military works with ICEYE but couldn’t say whether this specific satellite is involved.
Russia appears to be paying close attention to ICEYE-X36. Changing a satellite’s orbit to match another spacecraft’s path uses a lot of fuel, so it is not a decision taken lightly. Four Russian satellites made similar changes in May. However, it remains unclear whether ICEYE-X36 is specifically used to collect images of Ukraine.
Close approaches between satellites are not new, but this case is different. Russia, the United States, and China have all moved satellites close to those operated by other countries, mainly in geostationary orbit. Kosmos 2612 operates in low Earth orbit. As far as is publicly known, Russia has carried out similar approaches there, but the United States and China have not.
Victoria Samson of the Secure World Foundation pointed to two earlier Russian cases. In 2020, Kosmos 2543 came within about 30 kilometers of USA 245. In 2022, Kosmos 2558 approached USA 326 to within about 70 kilometers.
Both targets were classified US spy satellites operated by the National Reconnaissance Office. ICEYE-X36, by contrast, is a privately owned satellite, and Kosmos 2612 came much closer than in those earlier cases. Space law professor Aaron Brynildson told Axios that there is no strict legal limit on how close satellites can approach each other. However, countries generally avoid getting within six miles of another satellite.
Why do it? Samson lists a few options. Russia may want to learn the satellites’ capabilities and what they’re studying, or it may have interfered with sensors or communications. She leans toward a different reading: she thinks Russians are getting frustrated, in a stalemate for about six months, and this is a way to show military prowess in a way Ukraine can’t answer, since Ukraine matches Russia in drones but not in space.
RUSI’s June report is blunter about the options. It lists intimidation or interference through jamming, which uses radio noise to stop satellites from communicating. It adds that the range of options for protecting an ICEYE satellite is limited, and that defending satellites is a famous dilemma. LeoLabs says the event doesn’t establish hostile intent, but shows capabilities that could support intelligence collection, inspection, coercive signaling, interference or preparation for future counterspace operations.
ICEYE’s response was short: the company is aware, tracking closely, and says its constellation architecture is designed for continuity and resilience. CNN says it asked Russia’s defense ministry and Roscosmos for comment. The US Space Force had already described Russian satellites positioned near a Western commercial radar satellite used by Ukraine for imagery intelligence, according to Axios.
Private companies and independent observers, rather than the US Space Force, revealed the satellite encounter, highlighting the need for greater government transparency as space becomes more contested.
