Astroscale is a Japanese on-orbit-servicing leader (TSE:186A) whose ADRAS-J completed the world-first commercial mission to approach and image large debris at close range, with ELSA-M and ADRAS-J2 (capture and removal) following, on FY26 project income of JPY 11.5B ($71.1M, +89%) and a narrowing operating loss. It is converting to defense demand: a second Japanese MoD gripping-mechanism contract (JPY 999M, January 2026), a JAXA GEO-refueling selection, a UK military tracking-cubesat milestone, and a US Space Force refueling demo in the pipeline. Analysts see profitability around 2029.

Quantum Space is developing Ranger and Scout spacecraft for multi-orbit operations, on-orbit refueling, and propellant transfer to satellites in GEO.
Darker bar: ahead of the other company on that measure.
Quantum Space — co-founded by former acting NASA administrator Steve Jurczyk with Kam Ghaffarian IBX orbit — builds Ranger, a large maneuverable spacecraft platform for orbital mobility and space-defense missions, with a first flight targeted mid-2026 and explicit positioning toward cislunar operations and the Golden Dome-era defense market. It acquired electric-propulsion maker Phase Four (September 2025), bringing thrusters in-house, and announced in June 2026 it is going public via SPAC at a ~$1.2B valuation — capital and visibility well ahead of flight heritage. It is the most firepower-heavy pre-flight company in this batch.
