What is ClearSpace?
ClearSpace is a Swiss commercial active debris removal startup. The ClearSpace-1 mission, developed under ESA contract, is designed to capture and de-orbit a Vega rocket adapter (VESPA) currently in orbit. ClearSpace-1 is pre-flight as of mid-2026; the mission outcome is pending.
What ClearSpace is
ClearSpace is a Swiss commercial space company founded in 2018 as a spin-off from EPFL (École Polytechnique Fédérale de Lausanne). The company is developing active debris removal capabilities under contract to the European Space Agency (ESA). ClearSpace's flagship mission, ClearSpace-1, is designed to capture and de-orbit a Vega rocket adapter (VESPA) that has been in orbit since 2013.
Mission status
ClearSpace-1 is pre-flight as of mid-2026. The mission has had schedule revisions; the launch date has shifted multiple times during the development cycle. The framework records ClearSpace at the pre-flight tier with verification posture pending the in-flight demonstration.
The VESPA target is unique among debris removal demonstration scenarios because it is a cooperative-design debris object: the rocket adapter was designed for VESPA's primary mission and has a defined geometry the capture mechanism can plan against. This is structurally distinct from active debris removal targets that involve uncooperative debris with unknown attitude dynamics.
Verification posture
Pre-mission-result. Capability claims at maker-disclosed claim status, partially corroborated by ESA program documentation as the customer of record. In-flight capture and de-orbit capability is the verification threshold for active debris removal claims; ClearSpace has not yet crossed that threshold.
Per the verified-vs-claimed framework, the cohort context is the broader active debris removal sub-cohort. Astroscale ADRAS-J completed close-proximity inspection of a discarded H-IIA rocket upper stage but did not attempt capture; ELSA-d aborted the capture demonstration. Active debris capture remains at claim status across the cohort pending the first verified in-orbit capture and de-orbit.
Cohort context
ClearSpace operates alongside Astroscale and Starfish Space at the commercial orbital servicing tier. The active debris removal use case is structurally adjacent to satellite life extension: both require rendezvous, both require some form of attachment, but debris removal targets non-cooperative or partially-cooperative objects rather than operational satellites. Northrop Grumman SpaceLogistics MEV is the canonical commercial-success worked example in the broader sub-cohort.

Frequently asked questions
- Has ClearSpace-1 launched?
No. ClearSpace-1 is pre-flight as of mid-2026. The mission has had schedule revisions during the development cycle. The framework records ClearSpace at the pre-flight tier with verification posture pending the in-flight demonstration.
- What is the VESPA target?
VESPA is a Vega rocket adapter that has been in orbit since 2013. It is a cooperative-design debris object because the adapter was originally designed for VESPA's primary mission and has a defined geometry the capture mechanism can plan against. This is structurally distinct from active debris removal targets that involve uncooperative debris.
- Who is the customer of record for ClearSpace-1?
The European Space Agency (ESA). The mission is developed under ESA contract. ESA program documentation partially corroborates ClearSpace's capability claims at the development phase; in-flight verification is the threshold for ClearSpace's capture and de-orbit capability claims.
- How does ClearSpace compare to Astroscale ADRAS-J?
Both target debris removal use cases. ADRAS-J completed close-proximity inspection of a discarded H-IIA rocket upper stage but did not attempt capture; the mission was scoped as inspection-only. ClearSpace-1 is designed to attempt actual capture and de-orbit of the VESPA target. Both makers are structurally pre-capture-verification.
- Is ClearSpace autonomous?
The framework records autonomy capability at maker-disclosed claim status pending the in-flight demonstration. ClearSpace has not yet flown autonomy in operational mission scope; subsequent mission outcomes will refresh the autonomy verification posture.
- What is ClearSpace's longer-term mission roadmap?
ClearSpace has announced additional debris removal missions in the development pipeline, plus broader on-orbit servicing concepts. Specific mission outcomes and timelines are documented in ClearSpace's published communications and ESA program documentation.
ClearSpace verification posture pre-mission-result. ClearSpace-1 pre-flight as of mid-2026 with schedule revisions during development. Capability claims at maker-disclosed status partially corroborated by ESA program documentation. In-flight capture and de-orbit capability is the verification threshold. How DEPLOY verifies →
