Russian military satellite conducted close approach to Ukrainian-linked imaging satellite
Orbital tracking data shows a Russian spacecraft performed deliberate maneuvers in extreme proximity to a commercial Earth-imaging satellite, marking what analysts say is the first unsanctioned rendezvous operation in low-Earth orbit.

A Russian military satellite executed a series of controlled maneuvers bringing it into "extreme proximity" with ICEYE-X36, a commercial imaging satellite operated by a US company, according to orbital intelligence specialist LeoLabs. The incident represents what researchers characterize as an unprecedented unsanctioned close-approach operation between spacecraft in low-Earth orbit.
The encounter and its details#
The Russian spacecraft, Kosmos 2612, methodically closed the distance from several hundred kilometers to extremely close range over recent days. Once there, it repositioned itself multiple times around the ICEYE satellite, lingered in the vicinity for an extended stretch, and then gradually withdrew from the area.
By Friday of last week, Kosmos 2612 had settled into a station-keeping position 2 to 3 kilometers from ICEYE-X36. Over the weekend, the two satellites came within 500 meters of each other—possibly even closer—before shifting to positions ahead and behind the ICEYE craft. The proximity was so tight that LeoLabs' tracking radars occasionally struggled to identify the two objects as separate entities. "The behavior is consistent with sophisticated rendezvous and proximity operations (RPO)," LeoLabs noted in its assessment.
Background: months of tracking#
Military officials and independent observers have monitored Kosmos 2612 since its April launch aboard a Soyuz rocket from a Russian spaceport in the north. Shortly after reaching orbit, at least four of the six satellites deployed from that mission adjusted their orbits to align with ICEYE-X36's trajectory, establishing what appeared to be a coordinated shadow operation.
Why the tracking matters#
LeoLabs operates a global radar network capable of detecting objects as small as 2 centimeters in low-Earth orbit, providing the technical capability to distinguish even subtle changes in spacecraft position and behavior. The company emphasized that this encounter was fundamentally different from a routine orbital crossing, involving deliberate station-keeping, careful repositioning, sustained close proximity, and what amounted to a choreographed departure sequence—hallmarks of the kind of rendezvous maneuvers typically performed only during coordinated, pre-planned missions.
