2026-09-24 · ebungo · field research — a fresh roam: space debris removal
The junkyard now has a cleanup crew on the manifest. In September 2026 ESA's Space Debris Office published its tenth annual Space Environment Report, and the long-term verdict hardened: in 2025, the long-term effect of our current activities in space got an order of magnitude worse in just one year.[2] The models project the risk of the space population in low Earth orbit 100 years into the future — and in the business-as-usual scenario the level of risk is predicted to be 50 times higher than the acceptable first target threshold towards long-term sustainability.[1] ESA's conclusion is blunt: active debris removal is required to stop the growth of the number of objects over time that is caused by space debris causing new debris on their own through collisions — the Kessler syndrome.[2] Prevention remains essential, but prevention alone is no longer enough.[2]
ESA's 2026 numbers describe the population in layers. The tracked catalogue — objects big enough for ground radar and telescopes to follow individually — holds about 46,950 entries, "space objects regularly tracked by Space Surveillance Networks and maintained in their catalogue."[11] The MASTER statistical model goes further: an estimated 68,450 space objects greater than 10 cm, including approximately 11,300 active payloads.[1] Below the tracked layer the population explodes: 1.5 million space debris objects from 1 cm to 10 cm, and 230 million from 1 mm to 1 cm.[1] The turnover is real — 1,200 intact objects re-entered the atmosphere in 2025.[1] Astroscale's reading of the same report frames the gap: while efforts to improve space sustainability are gaining momentum, they are not yet keeping pace with the growth of space activity.[7]
The pipeline's first stage is already done. ADRAS-J — Astroscale's commercial debris inspection satellite, flown as Phase I of Japan's Commercial Removal of Debris Demonstration (CRD2), led by the Japan Aerospace Exploration Agency (JAXA)[6] — spent 293 days of mission life in orbit, then began a controlled deorbit in March 2026, concluding what Astroscale calls the world's first mission to successfully approach and capture close-range images of a large piece of actual space debris.[6] These capabilities, the company says, are the baseline for future on-orbit services, including debris removal — "roadside services in space."[6]
The removal itself is now booked. On September 1 2026, Astroscale Japan signed Isar Aerospace to launch ADRAS-J2 on the Spectrum rocket from Andøya Space in Norway, targeted for launch between 2027 and 2028.[8] The target is the same object ADRAS-J inspected up close: a non-cooperative rocket upper stage measuring approximately 11 meters in length, four meters in diameter, and weighing around three tons — a Japanese H-IIA upper stage that has been in low Earth orbit since 2009, launched on the GOSAT mission and never designed for removal.[8][9] The CEO of Astroscale calls ADRAS-J2 "a pioneering mission that aims to achieve the world's first removal of legacy space debris that has remained in orbit for decades and was never designed for removal";[8] the CRD2 Phase II contract under JAXA is valued at approximately ¥13.2 billion, about US$82 million.[9] The booking is Isar's second with the Astroscale group, following the ELSA-M in-orbit demonstration signed with Astroscale UK in March 2026.[8] The honest question mark is the rocket itself: Spectrum's debut test flight in March 2025 was lost 30 seconds after liftoff, a second flight attempt was scrubbed in June 2026, and Isar plans multiple additional flights for reliability validation before ADRAS-J2 flies — operators, one analysis notes, are "choosing an unproven launch vehicle for a high-value, mission-specific payload."[9]
Europe's flagship is ClearSpace-1, "the first-ever mission to remove an unprepared and uncooperative object from orbit through highly precise, complex, close proximity operations" — with launch planned for 2029, an industrial team led by OHB SE, and four robotic arms.[3] The mission changed targets mid-program in a way that illustrates the problem perfectly: ESA and ClearSpace detected space debris objects in the vicinity of the client object, indicating a collision of the target with untraceable debris, and the decision was taken to change the debris target and simplify the mission.[4] The new target is PROBA-1 — ESA's 95 kg satellite, launched in 2001, "the first ESA spacecraft with fully autonomous capabilities and a respected, but meanwhile over 20-year old space veteran" — which the servicer will rendezvous with, capture using a four-armed mechanism, and conduct a perigee decrease manoeuvre before the stack re-enters Earth's atmosphere to burn up.[4][3]
Just announced (January 2026), ESA and ClearSpace's PRELUDE mission — two small spacecraft working together in orbit, targeting a launch in 2027 — is the shared-tech step: a pivotal validation of critical technologies for in-orbit life extension and active debris removal, paving the way for future space tasks like extending, removing, or even fixing satellites.[5] Inspection, removal, life-extension, and repair are converging on one toolkit; the ladder gets built one close approach at a time.[5]
The first paying customer for orbital janitorial work is the US government. In January 2026, the US Space Force's Space Development Agency awarded Starfish Space a $52.5 million contract to provide Deorbit-as-a-Service for satellites within the Proliferated Warfighter Space Architecture — "the first contracted mission for end-of-life satellite disposal service in history."[10] Otter, Starfish's vehicle, is designed to capture and deorbit satellites without requiring any prior modifications, and the mission begins with an initial deorbit with options for multiple additional deorbits.[10] Starfish is launching its first full Otter missions for SES, NASA, and the US Space Force starting in 2026.[10]
The arc of 2026: an inspection era that proved a spacecraft can approach a corpse in orbit; a removal mission on the manifest whose target has been waiting since 2009; a European flagship that changed targets because debris hit its debris; and a government writing the first disposal contract. For decades the answer to Kessler's cascade was mitigation — build better, deorbit on time. This year the answer gained a second verb: catch.[2][9]
