A Russian military satellite, Cosmos 2612, has closed to roughly 3 miles, from a previous distance of more than 200 miles, of the U.S.-owned radar satellite that operates in a fleet that supports Ukraine, Axios reports<\/a>. The unapproved rendezvous in low Earth orbit, which astronomer Jonathan McDowell says may be the first of its kind, raises alarm in the West. The position change, which was likely not an accident as fuel is scarce, is probably a provocation and an attempt to spy on the satellite.<\/p>\n

New TLEs show that K2612 made a manuever on Oct 16 and is now stationkeeping within 5 km or less of ICEYE X36. To my knowledge this is the first LEO rendezvous of two active satellites where the owner of one of the sats did not give approval.October 17, 2026<\/a><\/p>\n<\/blockquote>\n

LeoLabs said in a statement Friday that the movement \u201cappears to be a deliberate approach\u201d toward ICEYE-X36, with uncertain intent and behavior that \u201cwarrants continued monitoring.\u201d Roughly 3 miles is too close for comfort in satellite terms<\/a>: there is no strict legal limit on how close satellites can get, but countries generally keep at least 6 miles (9.7 km) apart, University of Mississippi space law professor Aaron Brynildson told Axios. The approach was made without the owner\u2019s consent, and Russia hasn\u2019t said what the military satellite carries.<\/p>\n

Some clues may come from the target\u2019s operational purpose. ICEYE-X36 is a synthetic aperture radar (SAR) satellite which can image through cloud cover and at night. It was launched in March 2024 on a SpaceX Falcon 9. It\u2019s registered to ICEYE US, the U.S. arm of the Finland-founded company. The satellite, which is in a roughly 545 km (339 mi) sun-synchronous orbit, is part of a fleet that has supplied Ukraine with information since 2022. This includes a deal earlier this year with a customer in Ukraine\u2019s defense ministry, but a Ukrainian official told Axios it\u2019s unclear whether ICEYE-X36 itself supports the country; ICEYE and the Defense Department declined to comment.<\/p>\n

In May, the majority of the six military satellites Russia launched in April via a Soyuz-2.1b, Cosmos 2609\u20132614, shifted their orbits<\/a> about 0.8 degrees to match X36\u2019s orbital plane. Cosmos 2609 passed within 2.5 km (1.6 mi) on May 26. Cosmos 2612, on the other hand, drifted off X36\u2019s plane by about 0.24 degrees by Sept. 30, up to about 28 km side to side, according to Greg Gillinger, a space analyst with Integrity ISR.<\/p>\n

Then, Cosmos 2612 made separate burns from Sept. 30 through Oct. 16 to match altitude, eccentricity, and orbital period, Dutch satellite tracker Marco Langbroek wrote. By Saturday night, he estimated from public orbital data, it was within \u201ca few hundred meters or possibly (much) closer.\u201d<\/p>\n

These movements appear deliberate and cost a lot of fuel, which the Center for Strategic and International Studies calls \u201ca limited resource on a satellite.\u201d Close-proximity work can be benign, it says, but policymakers should assume the Russian satellite \u201ccould take an action that threatens the commercial satellite,\u201d and the U.S. and Europe should decide how to respond to any hostile act in space and make a statement on the decision. Back in July 2020, Russia\u2019s Cosmos 2543 released an object at up to 186 m\/s (416 mph) relative to itself, an action which was condemned by the U.S. and U.K.<\/p>\n

Intent was less clear earlier this year, when McDowell told Meduza the orbital data showed no sign of the stable, close distance that tracking ICEYE-X36 would require. Now, he says it is an unapproved meeting and is not alone. Gillinger says the setup \u201cremoves any remaining doubt for me that Cosmos 2612 is interested in ICEYE X36.\u201d Langbroek adds that \u201cI was skeptical\u201d at first but now calls it \u201ccompletely non-consensual,\u201d though he cautions it would be difficult to pin any X36 failures on 2612\u2019s actions.<\/p>\n

In a Reuters report less than two weeks ago, ICEYE CEO Rafal Modrzewski said the company moved its satellite after May, only to draw more Russian maneuvers, which Germany\u2019s Space Command head<\/a>, Maj. Gen. Michael Traut, described as \u201cchasing.\u201d Belinda Marchand, chief scientist at U.S. space intelligence firm Slingshot Aerospace, added that the moves may have been meant for surveillance, to prepare for future interference, or to signal capability. Western officials reportedly describe such trailing as a way to gather intelligence and test the West\u2019s tolerance.<\/p>\n

No statement from Russia is on record. Gillinger also told readers to \u201cwatch Cosmos 2611 and 2613, whose planes are converging on ICEYE X37\u2019s,\u201d with crossings expected around Nov. 6 and Nov. 15.<\/p>\n
