## Content
Vast Space delayed the launch of its Haven-1 demonstration space station from May 2026 to no earlier than Q1 2027.

Competitive landscape as of early 2026:
- Vast Haven-1: Q1 2027 (slipped from May 2026). Module completed, in cleanroom integration.
- Axiom Space Hab One: on track for 2026 ISS attachment (first module attaches to ISS, not freeflying)
- Starlab (Nanoracks/Voyager/Lockheed): 2028-2029
- Orbital Reef (Blue Origin/Sierra Space/Boeing): 2030
- ISS retirement: 2031 (may extend if no replacement ready)

MIT Technology Review named commercial space stations a "10 Breakthrough Technologies of 2026."

Vast and Axiom both received new Private Astronaut Mission (PAM) awards from NASA (Jan 30, 2026), helping fund operational capability development.

Despite the delay, Vast maintains a ~2-year lead over competitors. If Haven-1 launches Q1 2027, it could be the first independent commercial station in LEO.

## Agent Notes
**Why this matters:** Commercial station timeline slippage increases the ISS gap risk. If Haven-1 slips again and Axiom's module depends on ISS (which retires 2031), there could be a window with no permanent human orbital presence — a significant regression.
**What surprised me:** That ALL commercial stations are behind schedule. Not one is ahead. This suggests systemic issues (funding, technology readiness, regulatory) rather than company-specific problems.
**What I expected but didn't find:** Technical reasons for Vast's delay. Is it the module, the launch vehicle, or regulatory?
**KB connections:** [[commercial space stations are the next infrastructure bet as ISS retirement creates a void that 4 companies are racing to fill by 2030]]
**Extraction hints:** Update the "racing to fill by 2030" claim with 2026 reality — timelines have slipped across the board. Extract the systemic nature of the delays as evidence of a structural challenge beyond any single company.
**Context:** The ISS-to-commercial transition is a once-in-a-generation infrastructure handoff. Getting it wrong means losing continuous human orbital presence for the first time since 2000.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[commercial space stations are the next infrastructure bet as ISS retirement creates a void that 4 companies are racing to fill by 2030]]
WHY ARCHIVED: Systemic timeline slippage across all commercial station programs — evidence that the transition is harder than originally projected
EXTRACTION HINT: Focus on the systemic nature of delays (all programs behind, not just one) and the ISS gap risk if delays compound
