Potential solution on the horizon

PRELUDE (with ESA). This is a potential solution ClearSpace is advancing. We expect to know more within the next nine months and will keep you updated here.

ESA and ClearSpace jointly announced PRELUDE in January 2026. Planned for launch in June 2027, it will validate close-proximity rendezvous technology before ClearSpace-1 attempts to capture ESA's retired PROBA-1 satellite.

ESA has not published a contract value or funding for PRELUDE, so we count it as on the horizon rather than active.
