In February 2022, just weeks before Russia launched its full invasion of Ukraine, a satellite called Cosmos 2553 was sent into space. U.S. officials and analysts believe this satellite is linked to Russia’s efforts to develop nuclear anti-satellite (ASAT) weapons. While Cosmos 2553 is not thought to be a weapon itself, it likely plays an important role in gathering radar intelligence and testing how radiation affects spacecraft. This research could help Russia create a nuclear weapon capable of knocking out entire groups of satellites, like SpaceX’s Starlink network.

Over the past year, Cosmos 2553 has shown signs that it may be malfunctioning. In November 2024, the company LeoLabs noticed the satellite was spinning out of control, based on radar data. By December, more observations confirmed that the satellite was tumbling and likely no longer working properly. Another company, Slingshot Aerospace, saw similar irregular behavior in May 2024, including changes in the satellite’s brightness that suggested it was unstable. However, more recent observations hint that the satellite might have stabilized, though it’s unclear if it has fully recovered or remains damaged.

If Cosmos 2553 is indeed non-operational, it would be a major setback for Russia’s military space program. The satellite was placed in a high-radiation area about 2,000 kilometers above Earth—an orbit most satellites avoid—so it could test how systems perform under intense radiation and possibly simulate the effects of a nuclear event in space.

The U.S. intelligence community sees Cosmos 2553 as central to its concerns about Russia’s intentions to develop nuclear weapons for use in space. A weapon like that could wipe out large numbers of satellites, disrupting global communications, navigation, and military operations. Russia, however, insists that Cosmos 2553 is purely for scientific research. U.S. and NATO officials remain skeptical, especially because the satellite’s behavior and mission don’t fully match that explanation. NATO Secretary General Mark Rutte has warned that putting nuclear weapons in orbit would violate the 1967 Outer Space Treaty, which bans weapons of mass destruction in space.

This situation highlights the growing risks that come with the militarization of space. With more military and dual-use satellites being launched, the chances for misunderstandings or even conflict are rising. The U.S. Department of Defense and its allies are now investing heavily in better ways to track and understand space activities to avoid mistakes that could escalate into major problems.

 

Trump Skeptical of Putin’s Intentions in Ukraine

President Donald Trump has recently taken a sharper turn against Russian President Vladimir Putin, following a face-to-face meeting with Ukrainian President Volodymyr Zelenskyy at the Vatican. This marks a clear shift from Trump’s earlier, more cautious handling of Moscow during his second term. After speaking with Zelenskyy, Trump made it plain that he’s increasingly skeptical of Putin’s intentions, particularly in light of Russia’s continued missile strikes on Ukrainian civilian targets.
