ESA's Space Debris Office monitors space junk and defunct satellites orbiting Earth

The vast majority of reentering hardware burns up in our atmosphere
Some parts of a reentering object can survive to reach the surface
Most fragments land in oceans and are never seen again; some are found on land
In the history of spaceflight, no casualties from space debris have ever been confirmed
ESA experts provide reentry forecasts to our member countries and civil agencies around the globe
