In-space Servicing, Assembly, and Manufacturing (ISAM) State of Play 2025 Edition
COMPILED NOTES
Official NASA ISAM roadmap — catalogs active programs, technology gaps, and near-term demo missions
NASA ISAM State of Play 2025 Edition
Key Contributions
- Official NASA catalog of all active ISAM programs and their status
- Identifies technology gaps and investment priorities
- Maps near-term demonstration missions (2025-2028)
- Frames ISAM as critical enabler for sustained lunar presence, Mars missions, and space economy
Key Programs Tracked
- OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing) — robotic servicing demo
- MRV (Mission Robotic Vehicle) — DARPA RSGS program, GEO servicing, launch 2026
- Eta Space LOXSAT-1 — cryogenic fluid management demo, 2026
- Orbit Fab Kamino depot — commercial refueling services, 2026
- Starship — propellant transfer as ISAM enabler
Technology Gaps Identified
- Autonomous rendezvous and proximity operations (RPO) at scale
- Cryogenic fluid management in long-duration missions
- Standardized interfaces for servicing (multiple competing standards)
- In-space quality assurance and inspection
- Regulatory framework for commercial servicing operations
Market Context
- ISAM market growing driven by mega-constellation maintenance needs
- GEO satellite life extension is near-term commercial case
- LEO debris removal emerging as government-funded market
- In-space manufacturing still pre-commercial (TRL 2-5 for most approaches)
