ADRAS-J2

In Development

Debris removal servicer built for Phase II of JAXA's Commercial Removal of Debris Demonstration program. It returns to the same spent H-IIA upper stage that ADRAS-J surveyed, captures it with a robotic arm, and deorbits it.

Current status

Contracted by JAXA after ADRAS-J proved the approach was possible; Astroscale Japan's board finalized the contract terms in an August 19, 2024 regulatory filing at ¥12B (~$82.1M) excluding tax. The company mission page now quotes approximately ¥13.2B including tax. On September 1, 2026 Astroscale selected Isar Aerospace to launch ADRAS-J2 on Spectrum from Andoya in Japan FY2027 (April 2027-March 2028). Spectrum reached orbit on its second flight on September 5, 2026. Q1 materials said capture-mechanism vibration tests at Tsukuba were complete and satellite AIT had started.

Announced next steps from Astroscale that mention ADRAS-J2.

  1. 2027-2028

    Build and launch ADRAS-J2 to actually remove the rocket body

    Complete the Phase II servicer for JAXA's debris removal program and return to the spent H-IIA upper stage that ADRAS-J surveyed, this time capturing it with a robotic arm and deorbiting it. On September 1, 2026 Astroscale selected Isar Aerospace to launch ADRAS-J2 on a Spectrum rocket from Andoya Spaceport, Norway. Spectrum reached orbit on September 5, 2026. Q1 materials said capture-mechanism vibration tests at Tsukuba were complete and satellite AIT had started. It would be the first commercial removal of a large piece of debris from orbit.

  1. Astroscale picks Isar Aerospace to launch ADRAS-J2

    Astroscale Japan said on September 1, 2026 it selected Isar Aerospace to launch its ADRAS-J2 debris-removal spacecraft on a Spectrum rocket from Andoya Spaceport in Norway, targeting a 2027-2028 window. ADRAS-J2, contracted under JAXA's Commercial Removal of Debris Demonstration program, will attempt to capture and deorbit the same derelict rocket upper stage that Astroscale's ADRAS-J spacecraft inspected up close before completing its mission earlier this year. It is Isar's second Astroscale launch contract, after being picked in March 2026 to fly the ELSA-M demonstration mission.

  2. Astroscale finalizes ¥12 billion JAXA debris-removal contract

    Astroscale Japan's board finalized the contract for Phase II of JAXA's Commercial Removal of Debris Demonstration program, disclosed in an August 19 regulatory filing at roughly ¥12 billion ($82.1 million). The ADRAS-J2 spacecraft will grapple the same H-2A rocket upper stage currently being inspected by Astroscale's ADRAS-J and deorbit it, targeting launch in the company's fiscal year 2028.
