The Day Two Satellites Hit Each Other at 26,000 MPH

On February 10, 2009, an active Iridium communications satellite and a derelict Soviet military spacecraft slammed into each other 789 kilometers above Siberia. The collision produced more than 2,300 pieces of trackable debris that are still up there. Seventeen years later, the Iridium-Cosmos collision remains the event that made space debris a policy problem the world could no longer ignore.
