A Russian military satellite came within roughly one kilometre of a Finnish commercial spacecraft that supplies radar imagery to Western governments, the military and Ukraine. No attack has been reported, but the manoeuvre has exposed how quickly private space infrastructure can become entangled in a military confrontation.
The satellite, Kosmos 2612, approached ICEYE’s X36 on 17 October before moving away again. A space analyst cited by Reuters said the unusually close rendezvous could have been a rehearsal for a kinetic attack. That remains an assessment of the spacecraft’s behaviour, not proof of an attack plan or an order to destroy X36.
An approach that required precision
At the beginning of October, Kosmos 2612 was several hundred kilometres behind X36. On 17 October it began closing the gap, eventually reaching approximately one kilometre from the ICEYE satellite — about half a mile — before retreating to around 400 kilometres, or 250 miles.
Greg Hillingar, a senior space analyst at Integrity ISR, said such a close approach was more consistent with testing the possibility of a physical strike than with ordinary intelligence collection or electronic interference. His conclusion is based on the orbital manoeuvre and does not establish what Russia intended to do.
A satellite publicly described as being designed for servicing and inspection may have legitimate reasons to approach another spacecraft. But a rendezvous at such a distance requires detailed knowledge of the target’s position, accurate trajectory planning and the ability to manoeuvre in orbit. Those same capabilities could be used for inspection, surveillance, interference or a collision.
That ambiguity is at the heart of the danger. An impact would make an attack unmistakable. A controlled approach, however, can leave operators trying to determine whether they are watching a technical operation, a demonstration of capability, an intimidation tactic or preparation for something more destructive.
The activity around ICEYE has continued. Two Russian satellites are now drifting towards the orbit of another ICEYE spacecraft, X37. Their movement does not by itself show that an attack is imminent, but it keeps the company’s constellation under scrutiny and gives European governments another test of their ability to interpret and respond to unusual activity in space.
Why X36 matters
X36 is operated by ICEYE, a Finnish company whose satellites use synthetic-aperture radar to observe the Earth. Unlike optical systems, radar can produce useful imagery at night and through cloud cover. The resulting data can be used to monitor changes on the ground, assess damage and track military movements.
ICEYE supplies radar imagery to Western governments and military organisations, as well as to Ukraine. The same type of information can support border surveillance, crisis monitoring and civilian or humanitarian work. That broad user base means that the loss of one privately operated satellite could affect several governments and missions at once.
Russia launched Kosmos 2612 in April alongside five other military satellites. In May, four of those spacecraft were positioned near X36, according to space analysts. ICEYE later moved its satellite. The company’s decision to alter the spacecraft’s position underlines the practical difficulty of protecting a commercial asset once another state begins manoeuvring nearby.
Moscow has repeatedly warned that Western commercial satellites assisting Ukraine could be treated as legitimate targets for retaliation. Those warnings add political weight to the encounter, but they do not turn the approach into evidence that an attack was ordered. Nor does the available information establish that Kosmos 2612 was equipped or instructed to destroy X36.
The civilian system with military consequences
European governments and armed forces have become increasingly dependent on commercial providers for earth observation, communications, navigation, weather data and other space-based services. Private operators can often deploy systems more quickly than national programmes and make them available to several countries at the same time.
That flexibility is also a vulnerability. If a radar satellite were disabled, users could lose an important source of information at a critical moment. A replacement would not necessarily be available immediately. Other spacecraft might have to absorb the demand, while military users faced gaps in surveillance and more difficulty assessing opposing forces.
The consequences would not be limited to battlefield intelligence. Radar imagery can help authorities monitor borders, document damage and follow fast-moving crises. A physical attack on a commercial satellite could therefore disrupt a network serving military and civilian users without directly striking a government-owned spacecraft.
There is a wider environmental risk in orbit, too. A collision or destructive strike could produce fragments capable of damaging other satellites. An action against one vehicle could then threaten communications, observation and other services operated by companies and governments that were not involved in the original dispute.
This is why the old division between civilian and military space infrastructure is becoming harder to maintain. Ownership may be private, but a satellite’s strategic importance is shaped by what it enables. A company need not operate weapons to become relevant to a military confrontation; providing data to governments, armed forces or Ukraine may be enough.
A test for European defence planning
For the European Union and NATO, the episode increases the pressure to improve space-domain awareness: the ability to identify, track and interpret objects in orbit. More precise tracking could give operators earlier warning of unusual approaches. Resilient constellations, reserve capacity and alternative sources of information could reduce the effects of losing a single spacecraft.
Governments may also need to decide how they would respond if a commercial satellite used by several allies were attacked. The incident could affect multiple national security systems without hitting a military satellite belonging to any one country. That creates uncertainty over whether the event would be treated as damage to a private company, a disruption of allied capabilities or a broader act of aggression.
For operators, stronger protection is likely to mean higher costs, more redundancy and tighter procedures. Companies may need greater capacity to monitor nearby spacecraft and plan evasive manoeuvres, while governments may have to decide how much of that protection they are prepared to fund.
The known facts remain narrow but consequential: Kosmos 2612 approached X36 to about one kilometre and then withdrew; no attack has been reported. The Russian satellites now moving towards X37 will show whether Europe can recognise a genuine threat, protect privately owned infrastructure and coordinate a response before an ambiguous manoeuvre becomes irreversible damage.
