Report: Russian Nuclear-Linked Satellite ‘Spinning Uncontrollably’

A Russian satellite potentially linked to the country’s nuclear weapons program is “spinning uncontrollably” and appears to no longer be functioning, according to space-tracking data.

The erratic spinning has been going on intermittently for the past year, according to radar data from LeoLabs and optical data from Slingshot Aerospace shared with Reuters. The US previously alleged that the Russian satellite, known as Cosmos 2553, may be part of a weapons program that would enable Russia to bring down enemy satellite networks.

In a Pentagon press briefing last year, Major General Patrick Ryder said the Russian satellite is likely to be “a counter-space weapon presumably capable of attacking other satellites in low Earth orbit,” explaining that it resembled “previously deployed counter-space payloads from 2019 and 2022.”

Though US analysts don’t believe the spinning satellite itself is a weapon, it is believed to be a radar acting as a component of the wider anti-satellite military program. The Russian government has so far denied it is developing such a program.

According to Belinda March, Slingshot’s chief science officer, Cosmos 2553 now appears to have stopped spinning at the time of writing.

Russia has been accused of demonstrating anti-satellite capabilities before. In 2021, the US State Department claimed that the Russian government conducted a “dangerous and irresponsible” anti-satellite weapons test against one of its own satellites, creating debris that could endanger astronauts and the International Space Station.

Russian officials, at least covertly, have threatened US space infrastructure before. In 2022, Konstantin Vorontsov, reportedly a former acting Deputy Director of Russia’s Foreign Ministry Department, called the use of civilian and commercial space infrastructure an “extremely dangerous trend.” He added that this “quasi-civilian infrastructure may become a legitimate target for retaliation.” SpaceX’s Starlink has so far been instrumental in the Ukrainian war effort.

Earlier this year, General Michael Guetlein, the vice chief for the US Space Force, told Breaking Defense that Chinese satellites appeared to be practicing “dog fighting” in space.spac This means they were allegedly rehearsing movements that could allow them to take enemy satellites “hostage” while they were in orbit.
