Astroscale Japan Signs ADRAS-J2 Launch Deal With Isar Aerospace

Astroscale Japan Inc. and German launch provider Isar Aerospace have finalized an agreement to launch the ADRAS-J2 active debris removal mission on a Spectrum rocket from Norway during Japan’s 2027 fiscal year.

Announced in a joint press release on September 1, 2026, the contracts secures the launch vehicle for Phase II of the Japan Aerospace Exploration Agency (JAXA) Commercial Removal of Debris Demonstration (CRD2) project. The mission aims to become the first to capture and safely deorbit a large, non-cooperative piece of legacy space debris.

Targeting legacy orbital debris

The ADRAS-J2 (Active Debris Removal by Astroscale-Japan) spacecraft will target a derelict rocket upper stage that has remained in orbit for decades. The target debris weighs approximately three tons and measures roughly 11 meters in length and four meters in diameter. Because the upper stage was not designed with docking interfaces or navigational aids, it is classified by the industry as non-cooperative debris.

The upcoming mission builds upon the successful Phase I ADRAS-J mission, which concluded operations earlier in 2026. During Phase I, the Astroscale spacecraft demonstrated autonomous rendezvous and proximity operations. The vehicle conducted fly-around observations at a distance of 50 meters and achieved an ultra-close approach of 15 meters to the same rocket body.

“ADRAS-J2 is a pioneering mission that aims to achieve the world’s first removal of a large piece of legacy space debris that has remained in orbit for decades and was never designed for removal,” said Nobu Okada, Founder and CEO of Astroscale. “After more than half a century of human activity in space, the number of debris objects in orbit continues to increase, posing a growing threat to the long-term sustainability of the space environment.”

Expanding the Isar Aerospace partnership

The ADRAS-J2 mission will launch from Isar Aerospace’s dedicated pad at Andøya Space in Norway. The target launch window spans from April 2027 to March 2028, aligning with Japan’s 2027 fiscal year. The mission will utilize the Spectrum launch vehicle, which is designed to deliver payloads of up to one tonne to low Earth orbit (LEO).

This agreement represents the second launch contract signed between the Astroscale group and Isar Aerospace in 2026. On March 16, 2026, Astroscale’s United Kingdom subsidiary selected Isar Aerospace to launch the ELSA-M in-orbit demonstration mission. That separate mission is tasked with capturing an end-of-life Eutelsat OneWeb satellite.

“ADRAS-J2 is the kind of mission that defines the future of space operations. It requires precision, flexibility, and the ability to reach the right orbit at the right time,” said Stella Guillen, Chief Commercial Officer at Isar Aerospace. “This second launch agreement reflects the confidence our customers place in our team and technology and deepens a partnerships that is advancing the next generation of space missions.”

We view the consecutive contracts between Astroscale and Isar Aerospace as a strong indicator of maturing supply chains within the commercial space sector. By securing a second dedicated launch for a complex rendezvous mission, Astroscale is standardizing its deployment strategy across different international subsidiaries. For Isar Aerospace, capturing high-profile payloads from a Japanese government-backed initiative demonstrates growing confidence in the European micro-launcher market. Dedicated small launch vehicles like Spectrum are proving highly competitive for active debris removal missions, which require precise orbital insertion parameters that traditional rideshare missions cannot easily accommodate.
