Findings of the 6th European Conference on Space Debris

Findings of the 6th European Conference on Space Debris

For the better part of a week, space debris experts gathered in Darmstadt, Germany to discuss the current and future state of Earth’s orbital space. The conclusions were bleak: even cessation of all launches and 100% compliance with the 25 year deorbit rule would be insufficient to keep low Earth orbit debris from spiraling out of control.  Conference participants declared [...]
