The State of ISAM 2026
Industry-wide snapshot of ISAM maturity as of 2026 — who is operating, what is funded, and what milestones remain
The State of ISAM 2026
Abstract
Payload Space's 2026 ISAM survey splits the field into its three tiers and ranks their commercial maturity: manufacturing is closest to commercial viability, servicing is logging early wins (but needs routine RPO first), and assembly is furthest from commercial reality. The piece anchors the year's scheduled milestones and names the operators across each tier.
Key Contributions
In-Space Servicing — companies: Astroscale, Orbit Fab, Northrop Grumman, Starfish Space, Katalyst Space Technologies.
- Spacecraft are regularly launching for imaging and inspection; RPO (rendezvous & proximity operations) must become routine before commercial expansion.
- Market constraint, per Astroscale COO Chris Blackerby: "No one is putting in for a five-mission servicing [contract] to GEO."
- Scheduled: Astroscale + Orbit Fab — first GEO refueling mission for US Space Force in 2026; Astroscale ELSA-M de-orbit — NET May 2027 on Isar Aerospace; Northrop Grumman MRV — launching this year with robotic arms for repair.
Assembly — positioned as furthest from commercial reality; all current orbital objects must fit within rocket fairings. NASA's Ignition announcement supports lunar base infrastructure; D-Orbit's CEO envisions recycling defunct satellites as manufacturing feedstock.
Manufacturing — closest to commercial viability. Varda CRO Eric Lasker: the industry is "either at that tipping point, or we will look back a year or two from now as having already crossed it in early 2026." Reentry-vehicle startups are emerging rapidly. Voyager Technologies reported all commercial rack space on Starlab sold out in 2026.
Results
- Launch cost is the watershed variable; SpaceX Starship's emergence before decade's end is anticipated to unlock previously non-viable terrestrial product manufacturing in orbit.
