What is Astroscale?
Astroscale is a Japanese orbital servicing and debris removal company. The ELSA-d demonstration mission (2021) successfully demonstrated rendezvous but the magnetic capture demonstration was aborted after attitude anomalies. The ADRAS-J mission (2024-2025) completed close-proximity inspection of a discarded H-IIA rocket upper stage but did not attempt capture. Astroscale is publicly traded (TSE: 186A).
What Astroscale is
Astroscale is a Tokyo-based commercial space company focused on orbital servicing and debris removal. The company was founded in 2013 and is publicly traded (TSE: 186A). Astroscale operates across multiple satellite platforms targeting end-of-life servicing, debris removal, and refueling.
ELSA-d mission outcome
ELSA-d (End-of-Life Services by Astroscale - demonstration) launched in March 2021 on a Soyuz from Baikonur. The mission consisted of a servicer satellite and a client satellite. The servicer demonstrated rendezvous and approach with the client successfully. The magnetic capture demonstration was scheduled but aborted after the servicer experienced attitude anomalies during one of the attempted captures; the team determined that further capture attempts carried unacceptable risk and ended the active demonstration sequence.
ELSA-d operated through 2022 with reduced demonstration scope. The mission verified rendezvous capability at deployed-capability depth; the magnetic capture capability was not verified in the ELSA-d operational record.
ADRAS-J mission outcome
ADRAS-J (Active Debris Removal by Astroscale Japan) launched in February 2024 under JAXA's Commercial Removal of Debris Demonstration program. The satellite rendezvoused with a discarded H-IIA rocket upper stage (an existing piece of orbital debris) and performed close-proximity inspection and characterization over multiple operational phases through 2024-2025. ADRAS-J did not attempt capture; the mission was scoped as inspection-only.
Per the verified-vs-claimed framework, ADRAS-J verified rendezvous and inspection capability at deployed-capability depth. Capture capability was not in scope for ADRAS-J; subsequent missions (ADRAS-J2 or commercial extensions) are expected to attempt capture.
Verification posture
Astroscale has verified rendezvous and inspection capability across two missions (ELSA-d + ADRAS-J). Magnetic capture capability remains at claim status: the ELSA-d aborted capture attempt does not verify capture at deployed-capability depth, and ADRAS-J did not attempt capture. The framework records rendezvous and inspection as verified; capture as pending verification.
Cohort context
Astroscale operates alongside Northrop Grumman SpaceLogistics (MEV-1 and MEV-2 successful Intelsat servicing missions) in the orbital servicing sub-cohort. MEV-1 and MEV-2 are the canonical commercial successes; Astroscale's verification posture is partial at the demonstration tier. Starfish Space and ClearSpace are pre-flight as of mid-2026.

Frequently asked questions
- What did ELSA-d achieve?
ELSA-d demonstrated rendezvous and approach with the client satellite successfully. The magnetic capture demonstration was scheduled but aborted after attitude anomalies during an attempted capture; the team ended the active demonstration sequence after the anomaly. Rendezvous capability is verified; capture is not.
- Did Astroscale capture any debris with ADRAS-J?
No. ADRAS-J was scoped as inspection-only. The mission rendezvoused with a discarded H-IIA rocket upper stage and performed close-proximity inspection and characterization. Capture was not attempted; subsequent missions are expected to test capture capability.
- Is Astroscale still operating?
Yes. Astroscale is publicly traded (TSE: 186A) and operates across multiple commercial and government contracts including JAXA's CRD2 program. The framework records corporate-state continuation; subsequent missions will refresh the verification posture on specific capabilities.
- How does Astroscale compare to Northrop Grumman MEV?
MEV-1 and MEV-2 are the canonical commercial successes in orbital servicing: both docked with Intelsat satellites and extended their operational lives by years. Astroscale's verification posture is at the demonstration tier: rendezvous and inspection verified, capture pending. The two makers operate at structurally different verification states in the same sub-cohort.
- What is the JAXA CRD2 program?
Commercial Removal of Debris Demonstration. JAXA's program to demonstrate commercial active debris removal capabilities. ADRAS-J is the first CRD2 mission, scoped as inspection-only; subsequent phases are expected to attempt capture and de-orbit.
- What is the ELSA-d follow-up mission?
Astroscale has announced ELSA-M as the commercial follow-up to ELSA-d, targeting end-of-life servicing for OneWeb satellites. ELSA-M's mission outcome is pending; the verification posture on capture capability will refresh when ELSA-M flies.
Astroscale mission outcomes verified at company primary-source mission records plus JAXA program documentation plus tier-1 news coverage. ELSA-d rendezvous verified; capture aborted. ADRAS-J inspection verified; capture not attempted. Capture capability remains at claim status pending ELSA-M or subsequent capture-attempting missions. How DEPLOY verifies →
