Secretive Russian military satellites release mystery object into orbit
April 3, 2025
A trio of secretive Russian satellites launched earlier this year has released a mysterious object into orbit, sparking interest among space trackers and analysts.
The three satellites, designated Kosmos 2581, 2582 and 2583, launched on a Soyuz-2.1V rocket from Plesetsk cosmodrome early on Feb. 2 (GMT). Since then, the satellites, whose purpose is unknown, have displayed interesting behavior, while in a near-polar orbit roughly 364 miles (585 kilometers) above Earth.
In March, the satellites appeared to be conducting potential proximity operations, or maneuvering close to other objects in space, according to Jonathan McDowell, an astrophysicist and spaceflight activity tracker.
Following this, the U.S. Space Force cataloged a new object in orbit, which was possibly released by Kosmos 2581 on March 18.
