Space is crowded with debris: dead satellites, rocket parts, and collision fragments. They can collide into active satellites, creating more junk and leaving orbital regions non-usable. This is the Kessler Syndrome, a chain reaction of collisions that could ruin the future of space activities. 

To stop this disaster, the space environment needs two fronts of action: Mitigation and Remediation. 

Today, mitigating the creation new debris through new rules, monitoring, and collision-avoidance services is helping to turn around the problem. Unfortunately, this won’t be enough as avoiding collisions is getting exponentially harder with every additional debris and satellite in orbit.  

To achieve sustainability, the space environment needs remediation by removing old debris from orbit.
