# The commercial space station transition from ISS creates a gap risk that could end 25 years of continuous human presence in low Earth orbit

The ISS is scheduled for controlled deorbiting in January 2031 after a final crew retrieval in 2030, with SpaceX building the US Deorbit Vehicle under an $843 million contract. Four commercial station programs are racing to fill the gap: Vast (Haven-1 launching May 2026, Haven-2 by 2032), Axiom Space (PPTM docking to ISS in 2027, independent station by early 2028), Starlab by Voyager Space and Airbus (no earlier than 2028 via Starship), and Orbital Reef by Blue Origin and Sierra Space (targeting 2030). MIT Technology Review named commercial space stations one of its 10 Breakthrough Technologies of 2026.

The central anxiety is a potential capability gap. Axiom's timeline has already been reshuffled due to ISS deorbit timing and the need to support the deorbit vehicle. If commercial stations slip further, the US could face its first period without permanent crewed presence in LEO since November 2000.

This transition from government-owned to commercially operated orbital infrastructure represents a structural shift in how humanity maintains its presence in space -- from a single multinational government project to a competitive commercial market. NASA plans to begin purchasing orbital research services from commercial stations starting in 2028, becoming a customer rather than an operator. The success or failure of this transition will set precedent for how governments relate to commercial infrastructure in frontier environments.

## Evidence
- ISS deorbit scheduled January 2031, SpaceX Deorbit Vehicle contract ($843M)
- Vast Haven-1 (May 2026), Axiom PPTM (2027), Starlab (2028), Orbital Reef (2030)
- Continuous human orbital presence since November 2000
- MIT Technology Review — commercial stations named 2026 Breakthrough Technology

## Challenges
All four commercial station timelines face slippage risk. Axiom's financial difficulties and Axiom's PPTM-first approach is the most realistic gap hedge but depends on their survival as a company.

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 competitive landscape this gap risk plays out across
- [[Axiom Space has the strongest operational position for commercial orbital habitation but the weakest financial position among funded competitors]] — Axiom's financial instability is the single largest risk factor
