Autonomous Space Debris Removal Satellite Constellation CleanerBot Completes Initial Deployment: 12 Satellites Begin Capturing Low Earth Orbit Debris

The CleanerBot satellite swarm uses robotic arms and deployable net capture mechanisms to autonomously track and remove space debris larger than 10 centimeters in low Earth orbit.

Autonomous Space Debris Removal Satellite Constellation CleanerBot Completes Initial Deployment

On October 31, 2030, Swiss space cleanup company ClearSpace announced that all 12 satellites of its CleanerBot space debris removal constellation had completed on-orbit deployment and begun executing debris capture missions. This is the world's first commercially operational space debris removal system.

Low Earth orbit (LEO) contains approximately 36,000 debris objects larger than 10 centimeters and roughly 1 million objects larger than 1 centimeter. These debris travel at speeds of approximately 7 to 8 kilometers per second, and any collision can generate additional debris, triggering the "Kessler Effect" — cascading collisions that render entire orbital regions unusable.

ClearSpace CEO Luc Piguet stated: "Space debris is not a future threat; it is a present crisis. In 2029, the International Space Station performed 12 emergency maneuvers to avoid debris, a threefold increase from 2020. CleanerBot is humanity's first line of defense for protecting the space environment."

Each CleanerBot satellite is equipped with a pair of flexible robotic arms and a deployable net capture mechanism. As a satellite approaches a target debris piece, the robotic arms deploy the net to envelop and tighten around the debris, then drag it into the atmosphere to burn up. A single CleanerBot can remove approximately 30 debris pieces in the 10 to 50 centimeter size range.

CleanerBot's initial targets are fragments from ESA's retired satellite Envisat, which was decommissioned over 20 years ago. ClearSpace plans to expand the CleanerBot constellation to 36 satellites by 2031, covering the major debris-dense regions of LEO.

ESA has signed a service contract worth 120 million euros with ClearSpace, aiming to remove approximately 500 debris pieces annually. Japan's JAXA has also indicated it will procure CleanerBot services in 2031.
