# the ISS-to-commercial transition creates a structural gap risk where compounding delays could produce the first break in continuous human orbital presence since November 2000

Continuous human presence in low Earth orbit has been unbroken since November 2000 — over 25 years. The ISS-to-commercial transition threatens this record under a plausible delay scenario:

**The gap scenario:**
- ISS deorbits on schedule: January 2031
- Vast Haven-1 launches Q1 2027 but is a single-module demonstration station with limited crew capacity
- Axiom's first module is ISS-attached and cannot operate independently post-2031 without additional modules
- Starlab and Orbital Reef target 2028–2030, both dependent on Starship cadence
- Any additional slip of 12–18 months for the leading programs produces a window with no permanent crewed LEO infrastructure

**Why this matters beyond symbolism:**
Continuous crewed presence is not just a record — it represents accumulated institutional knowledge in life support operations, medical protocols, emergency response, and supply chain logistics. A multi-year gap would require rebuilding operational competency from scratch when the next station comes online.

**NASA's buffer:**
ISS operations have been extended before (from 2024 to 2031 already). NASA retains authority to extend further if no commercial replacement is ready, which is the most likely backstop. The $843 million SpaceX Deorbit Vehicle contract assumes 2031 but does not lock it.

**The asymmetry:**
The downside of a gap (loss of 25+ years of uninterrupted orbital operations, strategic regression, loss of research continuity) is much larger than the upside of retiring ISS on schedule to save operating costs (~$3–4B/year). This asymmetry argues for NASA using its extension authority if the commercial transition slips.

The gap risk is real but likely manageable through policy — the structural question is whether it will be managed proactively or reactively.

Relevant Notes:
- [[commercial space stations are the next infrastructure bet as ISS retirement creates a void that 4 companies are racing to fill by 2030]] — the "racing to fill" framing assumes competitive success; this claim captures the failure mode
- [[universal schedule slippage across all commercial space station programs in 2025-2026 indicates structural industry-wide constraints not company-specific failures]] — systemic slippage is the mechanism that activates this gap risk
- [[the 30-year space economy attractor state is a cislunar industrial system with propellant networks lunar ISRU orbital manufacturing and partial life support closure]] — a gap in crewed LEO presence would delay the cislunar attractor state by losing operational continuity
