Data indicates the Cosmos 2553 – which US officials claim is aiding Moscow’s development of nuclear anti-satellite weapon – may no longer be functional
A secretive Russian satellite in space that US officials believe is connected to a nuclear anti-satellite weapons program has appeared to be spinning uncontrollably, suggesting it may no longer be functioning in what could be a setback for Moscow’s space weapons efforts, according to US analysts.
The Cosmos 2553 satellite, launched by Russia weeks before invading Ukraine in 2022, has had various bouts of what appears to be errant spinning over the past year, according to Doppler radar data from space-tracking firm LeoLabs and optical data from Slingshot Aerospace, shared with Reuters.
