The technology for removing large, non-tumbling space debris is maturing. The technology for dealing with the far more numerous small and tumbling fragments is not. This gap defines the real shape of the orbital debris problem in 2026. The GAO’s April 2026 S&T report maps the current state of remediation technology with notable specificity. The most mature approach is robotic capture and tow — a spacecraft that physically grapples a piece of debris and either deorbits it into the atmosphere or relocates it to a graveyard orbit above geostationary altitude.
