## Content

Commercial space station developer Vast unveiled two significant hardware items in April 2026:
1. **Astronaut Flight Suit** — designed for Haven-1 crew operations, blending "fashion with functionality"
2. **Large Docking Adapter (LDA)** — described as "revolutionary," enabling larger vehicles to dock with Haven-1

No technical specifications were available in the NASASpaceFlight headline summary. The LDA appears designed to accommodate future Starship docking (given its "large" designation) beyond the standard IDSS/APAS interfaces.

Previous tracking: Haven-1 has been delayed from May 2026 target to Q1 2027 (confirmed in prior research sessions). In-Q-Tel (CIA venture arm) invested in Vast in November 2025. Space Force has kept "the door open to future human presence in orbit" — Vast is positioned as a potential government anchor customer.

## Agent Notes
**Why this matters:** The Large Docking Adapter announcement is strategically significant if it enables Starship to dock with Haven-1 — this would create a commercial station accessible to Starship crew (commercial and NASA) and position Haven-1 as a true commercial replacement for ISS rather than a smaller-scale facility. It also suggests Vast is planning for a station scale that goes beyond the initial 4-person Haven-1 design.

**What surprised me:** Haven-1 is a compact commercial station (~3,000 cubic feet pressurized volume, similar to a large house). A "Large Docking Adapter" implies Vast is planning for connection with much larger vehicles — likely Starship HLS or commercial Starship — for expansion modules or crew transfer. This is thinking beyond Haven-1 to a larger commercial station architecture.

**What I expected but didn't find:** Technical specs on the LDA diameter, docking force, or target vehicle compatibility. Without knowing what "large" means in interface terms, it's impossible to assess whether this is a Starship-class interface or just a wider IDSS.

**KB connections:**
- Relevant to: commercial space stations as Gate 1-cleared, Gate 2-blocked sector (from two-gate model)
- Relevant to: ISS extension / commercial station overlap mandate (Senate Commerce Committee provision)
- Relevant to: In-Q-Tel national security demand floor interest in commercial stations

**Extraction hints:** Low-priority claim: "Vast's Large Docking Adapter for Haven-1 suggests the company is planning for Starship-class vehicle docking, indicating ambitions beyond the initial small commercial station to a Starship-accessible facility architecture."

**Context:** Haven-1 targeting Q1 2027 launch. ISS extension to 2032 with 1-year overlap mandate means Haven-1 needs to operate concurrently with ISS for at least a year. The LDA may be Vast's way of differentiating Haven-1 from ISS by offering Starship compatibility that ISS cannot provide.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: Commercial stations sector (Gate 1-cleared, Gate 2-blocked) and Starship commercial ecosystem
WHY ARCHIVED: LDA announcement suggests Vast is designing for Starship docking — a meaningful architectural decision that differentiates commercial stations from ISS
EXTRACTION HINT: Very low specificity — wait for technical specs before extracting a claim. Archive as context/signal, not hard evidence.
