In early March 2026, a roughly 600-kilogram NASA spacecraft came down through the atmosphere with nobody steering it. Its entire career had been spent studying the radiation belts that shield the planet it was now falling back toward.
Van Allen Probe A launched in 2012 to map the fierce belts of charged particles that ring the Earth. When the mission ended, it was left in an orbit designed to decay on its own, and roughly fourteen years later it did exactly that, reentering uncontrolled. NASA expected most of it to burn up, while noting that a few hardened components could survive to the surface.
- Object: Van Allen Probe A (NASA)
- Mass: about 600 kg
- Launched: 2012, radiation-belt science
- Reentry: early March 2026
- Type: uncontrolled
Even the good missions end this way
This was a successful, well-run science mission. It still ended as uncontrolled falling space debris, because there was never a way to bring it down on command.
That is the rule, not the exception. The overwhelming majority of what is in orbit cannot deorbit itself, so "leave it in a decaying orbit and hope" remains the default endgame. Building an option besides hope, for the objects that cannot help themselves, is the whole point of Space Waste.
It spent its life watching the belts that protect us. Fitting, in a way, that its last act was a reminder of the mess we still have to clean up.
