COSMOS 1408 DEB, 50621
Orbit data source: Space-Track
COSMOS 1408 DEB, 50621 is space debris in LEO originally from a launch on Thu, 16 Sep 1982 UTC launched from the Plesetsk Missile And Space Complex (PKMTR). Cosmos 1408 debris is a result of deliberate destruction of the defunct Soviet-era reconnaissance satellite Cosmos 1408 by a Russian anti-satellite missile in 2021. This event added many debris pieces to Earth's orbit, complicating space navigation and increasing collision risks for operational satellites and the International Space Station. The Cosmos 1408 debris has heightened concerns about space safety and militarization, emphasizing the urgent need for comprehensive space debris management strategies.
