ClearSpaceRenens · 50-100 employees · Space & Satellites
No listed rolesBuilds robotic spacecraft that capture and deorbit defunct satellites and space debris for ESA and national space agencies.
ClearSpace-1
ESA-contracted mission to capture and deorbit the defunct PROBA-1 satellite using four robotic arms, targeting launch in the second half of 2026. It will be the first removal of an unprepared, non-cooperative space object from orbit, demonstrating the core technologies needed for recurring debris removal services.
PRELUDE
A two-spacecraft demonstration mission being developed with ESA's Space Safety Programme, targeting launch in 2027. The two craft will carry out complex autonomous rendezvous and proximity manoeuvres in real orbit, validating the navigation and sensor systems that underpin future inspection and debris removal operations at scale.
CLEAR
The UK's first Active Debris Removal mission, funded by the UK Space Agency, targeting the removal of two derelict UK-registered satellites from low Earth orbit above 700 km altitude. ClearSpace completed Phase 2 in May 2025, demonstrating key capture technologies and de-risking the mission ahead of the operational phase.
