Over the nearly 70 years of spaceflight, about 10 000 intact satellites and rocket bodies have reentered the atmosphere with many more to follow. Yet for such a ubiquitous event, we still lack a clear view on what actually happens to a satellite during its fiery last moments.

ESA is preparing the Destructive Reentry Assessment Container Object (Draco) mission that will collect unique measurements during an actual reentry and breakup of a satellite from the inside. A capsule especially designed to survive the destruction will transmit the valuable telemetry shortly after.
