Isar Aerospace to Launch Astroscale’s ELSA-M Space Debris Removal Mission

On March 16, 2026, Munich-based launch startups Isar Aerospace announced a landmark launch service agreement with Astroscale Ltd., the UK subsidiary of Japan-headquartered Astroscale Holdings Inc. According to the official press release, Isar Aerospace will launch Astroscale’s End-of-Life Services by Astroscale, Multiple (ELSA-M) In-Orbit Demonstration mission.

This agreement marks Isar Aerospace’s first contract dedicated to an active space debris removal mission. The ELSA-M spacecraft is designed to safely capture and deorbit multiple defunct client satellites from Low Earth Orbit (LEO) during a single mission. For this specific demonstration, the target is a retired Eutelsat OneWeb satellite, highlighting the active participation of major telecom operators in end-of-life orbital cleanup.

While the ELSA-M launch is projected for no earlier than 2028, the announcement arrives at a critical juncture for Isar Aerospace. The company is currently preparing for the second orbital test flight of its Spectrum rocket, scheduled for later this week from the Andøya Spaceport in Norway, a vital step in proving the vehicle’s reliability.

The ELSA-M Mission and Space Sustainability

Targeting Defunct Satellites

The ELSA-M mission represents a significant step in transitioning space debris removal from a theoretical concept to a viable commercial service. As detailed in the press release, the mission is primarily privately funded by Astroscale, with substantial backing from the UK Space Agency and the European Space Agency’s (ESA) Connectivity and Secure Communications programme under the “Sunrise Partnership.”

“ELSA‑M is a major step forward for commercial end‑of‑life services, building on Astroscale’s flight‑proven rendezvous and proximity operations capability,” stated Nick Shave, Managing Director of Astroscale UK.

Isar Aerospace also emphasized the importance of this partnerships in their official company statement, noting the broader environmental impact of the mission:

“This is our first involvement of active debris removal mission and we are proud to contribute to space sustainability by supporting Astroscale’s pioneering activities.”

Isar Aerospace’s Path to Orbit

Upcoming Spectrum Test Flight

Before the ELSA-M mission can take flight in 2028, Isar Aerospace plans to conduct several “multiplier launches” to establish the reliability of its proprietary two-stage Spectrum rocket. The immediate focus is the company’s second test-flights, dubbed Mission ‘Onward and Upward’.

Following a launch failure shortly after liftoff in early 2025, Isar Aerospace has been working diligently to return to the pad. According to company statements, a recent pressurization valve issue has been resolved, opening a launch window no earlier than March 19, 2026.

“We were able to quickly address the valve issue, clearing the way for our launch preparations… Our goal with this mission is to demonstrate real progress, and to achieve that, we will once again push our systems to their limits,” said Daniel Metzler, CEO and Co-founder of Isar Aerospace.

Scaling Production

To meet growing global demand for launch services, Isar Aerospace is actively ramping up its industrial capacity. In February 2026, the company announced an expansion of its testing facilities at the Esrange Space Center in Sweden. Industry research notes that this expansion will enable the testing of up to 30 Aquila rocket engines per month. Furthermore, manufacturing is already underway for rockets designated for flights three through seven, indicating a strong push toward regular commercial operations.

Broader Industry Context

AirPro News analysis

At AirPro News, we view the Isar Aerospace and Astroscale partnership as a critical indicator of the maturing European commercial space sector. Low Earth Orbit is becoming increasingly congested, with industry data tracking over 20,000 cataloged debris objects currently in orbit. Defunct satellites pose a severe conjunction risk to active constellations, such as Starlink and OneWeb, as well as crewed spaceflight missions.

The ELSA-M mission is highly relevant because it helps establish a circular space economy, proving that “de-orbit as a service” can function as a commercial business model rather than relying solely on government-funded research. Astroscale’s financial trajectory supports this maturation; in mid-March 2026, the company reported record revenue for the nine months ending January 31, 2026, alongside a reduced operating loss driven by cost-control programs and foreign-exchange gains.

By pairing a European launch startup with a UK-based payload operator to target a major telecom operator’s retired asset, this mission grounds the theoretical need for space cleanup in immediate, commercial reality. However, the success of this long-term vision relies heavily on Isar Aerospace achieving orbital success in its upcoming near-term test flights.
