Key points

  • Cosmos 2612 approached ICEYE-X36 from over 200 miles to 3 miles.
  • ICEYE-X36 is a US-owned radar satellite supporting Ukraine.
  • The movement is considered deliberate and a potential provocation.
  • Close approaches without consent are unusual and raise alarm.
  • Kosmos 2612 was launched in April on a Soyuz rocket.
  • Four of six satellites from the launch stalked ICEYE-X36.
  • Kosmos 2612 held station 2 to 3 kilometers away from ICEYE-X36.

Russian Satellite Nears US Craft

A Russian military satellite, Cosmos 2612, has significantly reduced its distance to the U.S.-owned radar satellite ICEYE-X36. The Russian satellite moved from over 200 miles away to within approximately 3 miles of the US craft. This maneuver occurred in low Earth orbit and was not approved by the owner of ICEYE-X36.

Potential Provocation and Espionage

Astronomer Jonathan McDowell noted this might be the first such unapproved rendezvous, causing alarm in Western nations. The deliberate change in position, which consumes scarce fuel, is likely a provocation and an attempt to spy on the US satellite. LeoLabs stated the movement "appears to be a deliberate approach" with uncertain intent, warranting continued monitoring.

Unusually Close Proximity

While there is no strict legal limit on satellite proximity, countries typically maintain a distance of at least 6 miles. The 3-mile distance is considered too close in satellite terms. Russia has not disclosed the payload of its military satellite, and the approach was made without the consent of ICEYE-X36's owner.

Target Satellite's Role

ICEYE-X36 is a synthetic aperture radar (SAR) satellite, capable of imaging through clouds and at night. Launched in March 2024, it is registered to ICEYE US, the American arm of a Finnish company. This satellite is part of a fleet that has provided information to Ukraine since 2022, including a recent deal with Ukraine's defense ministry, though it is unclear if ICEYE-X36 specifically supports Ukraine.

Orbital Adjustments

In May, several Russian military satellites, including Cosmos 2609–2614, adjusted their orbits to match ICEYE-X36's orbital plane. Cosmos 2609 passed within 1.6 miles on May 26. Cosmos 2612 subsequently made separate burns from September 30 through October 16 to match the altitude, eccentricity, and orbital period of ICEYE-X36, leading to its close approach.

How outlets covered it

A Russian military satellite, Kosmos 2612, performed a series of deliberate maneuvers to approach and loiter near ICEYE-X36, a US-operated commercial Earth-imaging satellite used by Ukraine. This marks the first known instance of an unsanctioned rendezvous in low-Earth orbit, raising concerns about space security and potential interference with commercial assets.

A Russian military satellite, Cosmos 2612, has moved from over 200 miles to approximately 3 miles of the US-owned ICEYE-X36 radar satellite, which is part of a fleet supporting Ukraine. This unapproved close approach in low Earth orbit is considered a potential provocation and an attempt to spy, raising concerns in the West.
