# Analysis: New Space Habitat Visitation Before End of 2027

Planning Assessment

To forecast whether humans will visit a new space habitat before end of 2027 (approximately 21 months from now), I need to evaluate:

• Current development timelines for Haven-1, Orbital Reef, Starlab, and Axiom Station
• Launch and crewed mission readiness dates
• Any recent delays or accelerations
• Technical readiness for crewed operations

Available Source Summary

The search results provided contain limited information for a comprehensive forecast. Based on the 2 sources available:

Source 1: modernmechanics24.com – “ISS Ending Soon, But Real Space Race for Orbit Just Begun”

• Limited details provided; mentions Haven-1 specifications (four astronauts, crew quarters, shared living space, laboratory)

Source 2: Times of India – “NASA plans to say ‘goodbye’ to International Space Station” (Date: Not specified in excerpt)

• Key facts: NASA signed $415.6 million agreements in 2021 with Blue Origin, Nanoracks, and Northrop Grumman for commercial space station designs. Multiple projects targeting launches between 2027-2029. Specific timelines mentioned:
• Axiom Station: First module expected to attach to ISS in 2027 (transitioning to independent operations later)
• Starlab: Planned 2029 launch (post-2027 deadline)
• Haven-1: Described as standalone station (no specific 2027 date given)
• Orbital Reef: Joint Blue Origin/Sierra Space project (no specific date given)

---

Critical Information Gap

The search results do not provide sufficient detail to answer this forecast question definitively. Specifically missing:

• Exact crewed mission dates for Haven-1, Orbital Reef, and other commercial stations in 2026-2027
• Current development status as of March 2026
• Recent timeline updates or delays
• Technical readiness assessments
• Starship space station development status (mentioned in background but not in search results)

The only habitat with a 2027 mention is Axiom Station, but its first module attaches to the ISS initially, which may not qualify under the resolution criteria excluding “the ISS.”

To provide an accurate forecast, additional sources would be needed, particularly:

• Recent press releases from Vast Space, Blue Origin, Sierra Space, and Axiom Space
• NASA updates on commercial LEO transitions
• Current technical reviews and certification status
• Industry timelines as of Q1 2026

Detailed Rundown of Relevant News

The most advanced candidate for a new space habitat visited by humans before the end of 2027 is Vast Space’s Haven-1, a single-module commercial station designed for short crewed visits.[3][1] As of January 20, 2026, Vast announced a delay from mid-2026 to no earlier than Q1 2027 for its uncrewed Falcon 9 launch, citing integration priorities while primary structure and testing milestones were met (e.g., structural testing complete by November 2025, assembly advancing with thermal and avionics systems).[2][1] Post-launch commissioning is planned for about two weeks to verify pressure, attitude control, and safety for SpaceX Crew Dragon docking, with crewed missions (up to 4 astronauts for 10-14 days) potentially starting as early as two weeks after launch—placing a first human visit in Q2 2027 if on schedule—though up to three years is possible; Vast CEO Max Haot stated a “strong incentive to send a crew as quickly as safely possible,” with one mission already contracted and crew training underway for 6-12 months.[2][4] Haven-1’s precursor Haven Demo launched November 2, 2025, succeeded, and deorbited in February 2026, validating technologies.[3] NASA’s February 2026 selection of Vast for a private astronaut mission targets the ISS in 2027, not Haven-1, but underscores Vast’s crew capabilities.[11]

Blue Origin’s Orbital Reef, a multi-use “business park” at ~250-400 km altitude under NASA CLD Phase 1, shows no updated timelines for launch or crewed visits as of March 24, 2026; earlier projections eyed 2027 operations, but progress is linked to New Glenn rocket development without recent confirmations of pre-2028 human access.[7][6] Voyager Technologies’ Starlab, with partners like Lockheed Martin and NASA, completed preliminary design review by March 2025 for a 2028 Starship launch (some sources say 2029), with initial operational capability post-2027 but no first human visit before 2028 specified.[8][9]

NASA’s consideration of SpaceX Starship as a LEO station (announced June 2023) remains conceptual under unfunded CCSC-2, with no deployment or crewed timelines as of the July 2023 article, and recent Starship news focuses on Artemis lunar milestones rather than habitats.[10] NASA’s broader commercial LEO program (as of August 2024) supports multiple stations like Axiom (ISS-attached initially), Orbital Reef, and Starlab, but none report independent human visits before 2028; Axiom modules do not qualify as they extend the ISS.[12] No other new independent habitats (e.g., no Chinese beyond Tiangong) show pre-2028 crewed plans in recent sources. Recent Haven-1 updates (January-March 2026) indicate positive momentum toward Q1 2027 launch and potential rapid crewed follow-on, per company statements, while competitors lag.[2]

However, based on the text information provided in the question background and resolution criteria, here is what can be assessed:

Key Programs and Status (as of March 2025 knowledge):

1. Haven-1 (Vast Space) — Noted as “most likely to be first.” Vast Space had been targeting a launch window around 2025-2026, with a crewed mission planned using a SpaceX Dragon capsule. This is the strongest candidate to resolve the question “Yes” before end of 2027.
2. Orbital Reef (Blue Origin) — Referenced via blueorigin.com/destinations. Development timeline has generally been projected for late 2020s, making a crewed visit before end of 2027 unlikely.
3. Starlab (Voyager Technologies) — Referenced via voyagertechnologies.com/starlab/. Target launch was generally around 2028, making a crewed visit before end of 2027 unlikely.
4. SpaceX Starship as station — Referenced via space.com article about NASA considering it. Still in early conceptual/consideration phase; unlikely to host humans as a habitat before end of 2027.

Resolution Metric:

• Requires humans visiting (not just launching) a new space habitat that is not ISS or Tiangong before December 31, 2027.

GPT Binary response:

The forecast is mostly a forecast on Haven-1.

Why:

• Haven-1 has the only concrete near-term path. The January 2026 reporting is recent and fairly specific: uncrewed launch slipped to no earlier than Q1 2027, with a crewed Dragon visit potentially following after a short commissioning period. Its structure is complete, integration is underway, a precursor demo flew successfully, and at least one mission is contracted.
• Orbital Reef and Starlab look materially later. Recent sources still do not give strong pre-2028 crewed timelines. Their default path is outside this market window.
• Starship-as-station is still conceptual for this purpose.
• Axiom is probably not the out here. A module attached to ISS is likely to be treated as part of ISS for resolution, or at least too ambiguous to lean on.

So the question reduces to: can a startup-built, first-of-kind habitat get to orbit, check out safely, and host a human mission within the next 21 months?

My base-rate instinct says No by default. New crewed habitats are rare, and space-station schedules slip constantly. Even after launch, crewed use is a second hurdle, not an automatic consequence. Safety/regulatory gating is severe.

But the positive case is real:

• Falcon 9 and Crew Dragon are mature systems, lowering transportation risk.
• Haven-1 is relatively modest compared with a full multi-module station.
• Vast has tangible hardware progress, not just PowerPoints.
• The time window is long enough that a slip from Q1 2027 to mid/late 2027 can still resolve Yes.

Rough decomposition:

• Chance Haven-1 launches by end-2027: around the high-50s to low-60s.
• Conditional on launch, chance humans visit it by end-2027: around mid-60s.
• That puts Haven-1 alone around the high-30s.
• Add a small amount for other stations or favorable resolution ambiguity.

That yields a forecast in the low-40s, not a coin flip.

Shorter/longer checkpoints I’d use:

• By end-2026: very low, since Haven-1 is already delayed to 2027.
• By mid-2027: meaningful but still well below even odds.
• By end-2028: better than even, because additional slippage still leaves time.

Key assumptions most likely to matter:

1. Haven-1 does not slip past 2027.
   Failure chance: about 40.
   If this fails, the market probably resolves No unless an unlikely alternative succeeds.
2. If Haven-1 launches, it can be commissioned and cleared for a crew visit quickly enough.
   Failure chance: about 35.
   This is the most underappreciated second-step risk.
3. No alternative station unexpectedly beats Haven-1 or qualifies via an ambiguous interpretation.
   Failure chance: about 15.
   This is the main upside tail to a No-centered base case.

Given my own tendency toward overconfidence, I shade slightly downward from an initial mid-40s instinct.

Reasoning Through: New Space Habitat Visited by Humans Before End of 2027

Identifying the Key Candidate

The only realistic candidate is Vast Space’s Haven-1. All other options (Orbital Reef, Starlab, SpaceX Starship station) are either conceptual or targeting 2028+ launches. Axiom’s first module attaches to the ISS and would likely not qualify.

Breaking Down Haven-1’s Path to Resolution

Step 1: Will Haven-1 launch before end of 2027?

As of January 2026, Vast delayed from mid-2026 to “no earlier than Q1 2027.” Primary structure is complete, with systems integration targeting fall 2026 close-out, then Falcon 9 integration.

Space projects routinely slip. However, Haven-1 is a single-module station using a proven rocket (Falcon 9), with strong funding and a successful Haven Demo mission (Nov 2025–Feb 2026).

My estimated launch timing distribution:

• Q1 2027: 12%
• Q2 2027: 22%
• Q3 2027: 15%
• Q4 2027: 10%
• 2028+: 41%

P(launch before end 2027) ≈ 59%

Step 2: Given launch, will a crewed visit happen before end of 2027?

Post-launch commissioning takes ~2 weeks minimum, then a Dragon crew mission. One mission already contracted, crew training underway. But this is an unprecedented first commercial station crewing — unexpected technical issues are likely.

Conditional probabilities by launch quarter:

• Q1 launch → ~80% crewed visit by EOY 2027
• Q2 launch → ~70%
• Q3 launch → ~50%
• Q4 launch → ~20%

Combined calculation:

• Q1: 0.12 × 0.80 = 9.6%
• Q2: 0.22 × 0.70 = 15.4%
• Q3: 0.15 × 0.50 = 7.5%
• Q4: 0.10 × 0.20 = 2.0%
• Other habitats: ~1%

Total ≈ 35.5%

Critical Assumptions to Stress-Test

1. Haven-1’s timeline won’t slip beyond 2027 (~41% it does slip past 2027). This is the biggest risk — space development delays are the norm, not the exception.
2. Commissioning will proceed smoothly enough for crewed visits (~20-25% chance of major technical issues post-launch delaying crew indefinitely). First-of-kind station operations carry significant risk.
3. No regulatory/safety showstoppers preventing crewed operations (~10% chance). NASA/FAA may impose additional requirements.

Calibration Adjustments

• Historical overconfidence correction: I tend to overestimate novel technological milestones
• Base rate for positive resolution in forecasting tournaments: ~35%
• Space industry “on time” base rate is notoriously low (~25-35%)
• However, 21-month window provides meaningful buffer

Slight downward adjustment from ~35% to account for systematic overconfidence in novel space milestones.

Probability: 25%
The extracted probability is: 25%

Reasoning

Key Candidate: Haven-1 (Vast Space)

Haven-1 is clearly the leading candidate, as it’s the most advanced new commercial space station in development. Key facts:

• January 2026: Launch delayed from mid-2026 to “no earlier than Q1 2027”
• Primary structure complete as of January 2026; integration of thermal/avionics systems underway
• Haven Demo precursor mission successfully launched Nov 2025, deorbited Feb 2026
• Crewed Dragon visits could begin “as early as two weeks” after uncrewed launch
• One crewed mission already contracted via SpaceX; crew training in progress (6-12 months)

Other Candidates

• Orbital Reef (Blue Origin): No firm timeline; tied to New Glenn development; unlikely before 2028
• Starlab (Voyager): Targeting 2028-2029 launch; not feasible before 2027
• Axiom Station: First module attaches to ISS (likely disqualified under resolution criteria)
• SpaceX Starship as station: Still conceptual/unfunded

Probability Decomposition for Haven-1

P(Launch in 2027):
Already slipped once (~6-9 months). Space projects commonly slip further. However, primary structure is built, using proven Falcon 9, and Haven Demo was successful.

• Q1 2027: ~20%
• Q2 2027: ~20%
• Q3 2027: ~10%
• Q4 2027: ~5%
• 2028+: ~45%
• Total P(2027 launch) ≈ 55%

P(Crewed visit in 2027 | launch timing):
“Two weeks” commissioning is optimistic for a first-of-its-kind station. More realistic: 1-3 months minimum. Dragon scheduling also adds lead time.

• If Q1 launch: ~65% (6-9 months remaining)
• If Q2 launch: ~50%
• If Q3 launch: ~30%
• If Q4 launch: ~8%

Combined Haven-1: 0.20×0.65 + 0.20×0.50 + 0.10×0.30 + 0.05×0.08 ≈ 0.13 + 0.10 + 0.03 + 0.004 ≈ 0.264

Other habitats add ~2%

Critical Assumptions That Could Alter Forecast

1. Haven-1 integration stays on track (~55% it launches in 2027) — if integration reveals serious issues, could slip to 2028. Failure probability: ~45%.
2. Commissioning goes smoothly enough for rapid crewed visit — for a first-of-its-kind station, unexpected issues during orbital testing could delay crewed missions by months. Failure probability: ~35-40%.
3. No major programmatic/funding disruption — Vast is privately funded; economic downturns or leadership changes could change priorities. Failure probability: ~5%.

Calibration Check

• Historical base rate for “first-of-its-kind” space milestones meeting announced timelines: ~30-40%
• Accounting for overconfidence bias in my forecasting
• The timeline is tight but not impossible; ~21 months remain

Probability: 25%
The extracted probability is: 25%

Reasoning and Analysis

Primary Candidate: Haven-1 (Vast Space)

Haven-1 is by far the most advanced new space habitat candidate. Key timeline facts as of early 2026:

• January 20, 2026: Vast announced a delay from mid-2026 to “no earlier than Q1 2027”
• Primary structure is complete; integration of thermal, avionics, and other systems is underway
• Haven Demo (precursor) successfully launched November 2025 and deorbited February 2026
• Crewed Dragon visit planned potentially ~2 weeks post-launch
• One crewed mission already contracted with SpaceX; crew training underway

Other Candidates

• Orbital Reef: No firm launch timeline; tied to New Glenn development; almost certainly post-2027 for crewed visit
• Starlab: Targeting 2028-2029 launch; not viable for this question
• SpaceX Starship station: Conceptual only
• Axiom: First module attaches to ISS; may not qualify under exclusion criteria

Probability Decomposition for Haven-1

Launch timing distribution (given “no earlier than Q1 2027” stated Jan 2026):

• Q1 2027: ~15%
• Q2 2027: ~20%
• Q3 2027: ~15%
• Q4 2027: ~10%
• After 2027: ~40%

P(crewed visit before Dec 31, 2027 | launched in that quarter):

• Q1 launch → ~75% (ample time)
• Q2 launch → ~65%
• Q3 launch → ~50%
• Q4 launch → ~20% (very tight)

Combined: 0.15×0.75 + 0.20×0.65 + 0.15×0.50 + 0.10×0.20 = 0.1125 + 0.13 + 0.075 + 0.02 = ~34%

Adding ~1-2% for other habitats: ~35-36%

Key Assumptions and Their Failure Probabilities

1. Haven-1 launches in 2027 at all (~60% probability it does). If it doesn’t, the question almost certainly resolves No. Space projects routinely slip — “no earlier than Q1 2027” is optimistic company language, and another 6+ month slip is quite plausible.
2. Crewed visit follows rapidly after launch (~65% if launched before Q3 2027). Vast plans just 2 weeks of commissioning, which is aggressive for a first-of-its-kind station. Technical issues could delay crew access for months.
3. No major technical failure on station (~85% probability it works). Novel hardware failures, pressurization issues, or attitude control problems could prevent crew visits even if launched on time.

Calibration Adjustments

• Historical overconfidence correction: I tend to overestimate probabilities
• Base rate for positive resolution: ~35% across all forecasting questions
• Space program delays are the norm, not the exception
• However, the hardware maturity is genuine (structure complete, proven launch vehicles)

Probability: 25%
The extracted probability is: 25%

Gemini Binary response:

This forecast assesses the probability of humans visiting a new, non-ISS/Tiangong space habitat before the end of 2027. The analysis hinges on the progress of several commercial space station projects, with one clear frontrunner.

Analysis of Candidates

1. Orbital Reef (Blue Origin) & Starlab (Voyager/Nanoracks): Both projects are part of NASA’s Commercial LEO Destinations program. However, current timelines place their earliest operations in 2028 or later. Starlab is explicitly targeting a 2028 launch. Orbital Reef’s schedule is less firm and tied to the development of the New Glenn rocket, making a crewed mission before the end of 2027 highly improbable.
2. SpaceX Starship Habitat: While NASA is exploring the concept of using Starship as a space station, this remains in a very early, unfunded study phase. SpaceX’s operational focus for Starship is on launch system development and the Artemis lunar missions. A human-rated habitat variant being deployed and visited within the next 21 months is not a realistic scenario.
3. Axiom Station: Axiom’s first module is planned to attach to the International Space Station (ISS) in 2027. The resolution criteria explicitly exclude the ISS. As Axiom will initially be an extension of the ISS, any visit to it would not count towards a “Yes” resolution.
4. Haven-1 (Vast Space): This is the only candidate with a plausible, albeit aggressive, timeline for a 2027 crewed mission. Therefore, the probability of this question resolving “Yes” rests almost entirely on the success of the Haven-1 mission timeline.

Haven-1 Timeline and Risk Assessment

Vast Space’s Haven-1 is a small, single-module station planned for launch on a SpaceX Falcon 9, to be visited by crews on a SpaceX Crew Dragon.

• Current Schedule: As of January 2026, Vast announced a delay of the uncrewed launch from mid-2026 to “no earlier than Q1 2027.” While the primary structure is complete, this delay was attributed to system integration needs.
• Post-Launch Plan: Following a successful launch, a commissioning period of approximately two weeks is planned to verify all systems. A crewed mission could follow as soon as two weeks after that.
• Best-Case Scenario: A launch in mid-Q1 2027 (e.g., February) could lead to a crewed visit as early as March 2027, leaving a substantial buffer of over nine months before the resolution deadline.

Key Assumptions and Probabilities

The forecast is determined by a sequence of events, each with its own probability of success or delay. Failure or significant delay in any one step jeopardizes the 2027 deadline.

Assumption: Haven-1 Launch Schedule.

GPT Binary response:

This is mostly a Haven-1 question.

Reasoning:

• Outside view: brand-new human space habitats are extraordinarily rare, and space timelines slip a lot. A project already moved from 2026 to “no earlier than Q1 2027” should not be treated as likely to hit the new date exactly.
• Inside view: Haven-1 is not vaporware anymore. The structure is complete, systems integration is underway, a precursor demo flew successfully, Falcon 9 and Crew Dragon are mature, and Vast says a crew could visit roughly two weeks after launch if commissioning goes well. That is real progress.
• But the path to resolution still requires multiple things to go right in sequence:

1. Haven-1 launches by late enough in 2027 to still leave time for a crewed visit.
2. It survives commissioning and proves safe enough for docking/crew.
3. SpaceX/Vast actually execute the crewed mission before Dec. 31, 2027.

• Competition is weak: Orbital Reef and Starlab both still look more like 2028+ stories. Starship-as-station is too conceptual for this horizon. So if Haven-1 misses, the question probably resolves No.
• Resolution ambiguity: I would mostly exclude ISS-attached Axiom modules here, because the question/background clearly centers on new standalone habitats and explicitly says “not the ISS.” If a resolver counted an Axiom module attached to ISS as a “new habitat,” that would raise the Yes odds somewhat, but I would not lean on that.

Rough decomposition:

• Haven-1 launches by end of 2027: about 60%
• Crewed visit by end of 2027 conditional on launch by then: about 68%
• So Haven-1 path: about 41%
• Add a few points for all other paths combined / ambiguity: about 4%
• Then apply a small discount for chronic forecaster overconfidence and schedule optimism.

Useful time-slice check:

• By end of 2026: about 1%
• By end of Q2 2027: about 18%
• By end of 2027: about 45%
• By end of 2028: about 72%

Key assumptions that could most change the forecast:

1. Haven-1 does not slip materially beyond 2027.
   Chance this assumption is wrong: about 45%.
   If wrong, the question likely resolves No.
2. A successful uncrewed Haven-1 can be crew-cleared quickly.
   Chance this assumption is wrong: about 30%.
   A launch without a timely crewed visit does not help.
3. No other qualifying habitat beats Haven-1 before end-2027.
   Chance this assumption is wrong: about 15%.
   This is the main upside tail to a Yes resolution even if Haven struggles.

Net: the leading path is credible, but there is only one truly live near-term candidate, and first-of-kind orbital hardware plus crew ops tend to slip.

The extracted probability is: 45%

GPT Binary response:

This looks like a Haven-1 question with a thin tail of other possibilities.

Why I’m not higher:

• The resolution requires an actual human visit, not just launch of a habitat.
• New crewed space infrastructure has a strong history of slipping.
• Haven-1 already slipped to no earlier than Q1 2027 in January 2026.
• A first-of-kind free-flying habitat has multiple gates: launch, on-orbit checkout, life support verification, docking, crew safety approval, mission scheduling.

Why I’m not lower:

• Haven-1 is meaningfully more advanced than the alternatives.
• Recent reporting says the primary structure is complete, integration is underway, the precursor demo succeeded, and the mission architecture uses relatively mature systems: Falcon 9 + Crew Dragon.
• Vast explicitly says a crewed visit could occur shortly after launch if checkout goes well.
• There is still about 21 months until resolution, which gives some cushion for moderate slips.

How I weight the candidates:

• Haven-1: overwhelmingly the main path to Yes.
• Orbital Reef: recent material gives no concrete pre-2028 crew timeline; I treat this as a low-probability backup.
• Starlab: official/press timelines point to 2028 or later; very unlikely before end-2027.
• Starship as station: still too conceptual for this window.
• Axiom: even if an Axiom module attaches to ISS in 2027, I would not want to rely on that counting, because the criteria explicitly exclude the ISS and the listed source focus is elsewhere.

Rough decomposition:

• Probability Haven-1 launches by end-2027: about 60%
• Probability of a human visit by end-2027 conditional on launch: about 65%
• Combined Haven-1 path: about 39%
• Add a few points for non-Haven paths / resolution ambiguity: about 4%
• Total: about 43%

Shorter/longer timeline check:

• By end-2026: about 3%
• By mid-2027: about 18%
• By end-2027: about 43%
• By end-2028: about 68%

Key assumptions most likely to be wrong and most important:

1. Haven-1’s current schedule is only moderately optimistic, not wildly optimistic.
   Chance this assumption fails: about 45%
2. If Haven-1 reaches orbit, checkout and crew-safety validation will be fast enough for a 2027 visit.
   Chance this assumption fails: about 35%
3. No other habitat besides Haven-1 meaningfully enters the race before end-2027.
   Chance this assumption fails: about 15%
   (This assumption, if wrong, mostly pushes the forecast upward.)

Given the base rate of delays in space projects, the rarity of first-time crewed habitats, and the fact that only one realistic near-term candidate is visible, I land below even odds but well above a longshot.

Median reasoning:

The forecast is mostly a forecast on Haven-1.

Why:

• Haven-1 has the only concrete near-term path. The January 2026 reporting is recent and fairly specific: uncrewed launch slipped to no earlier than Q1 2027, with a crewed Dragon visit potentially following after a short commissioning period. Its structure is complete, integration is underway, a precursor demo flew successfully, and at least one mission is contracted.
• Orbital Reef and Starlab look materially later. Recent sources still do not give strong pre-2028 crewed timelines. Their default path is outside this market window.
• Starship-as-station is still conceptual for this purpose.
• Axiom is probably not the out here. A module attached to ISS is likely to be treated as part of ISS for resolution, or at least too ambiguous to lean on.

So the question reduces to: can a startup-built, first-of-kind habitat get to orbit, check out safely, and host a human mission within the next 21 months?

My base-rate instinct says No by default. New crewed habitats are rare, and space-station schedules slip constantly. Even after launch, crewed use is a second hurdle, not an automatic consequence. Safety/regulatory gating is severe.

But the positive case is real:

• Falcon 9 and Crew Dragon are mature systems, lowering transportation risk.
• Haven-1 is relatively modest compared with a full multi-module station.
• Vast has tangible hardware progress, not just PowerPoints.
• The time window is long enough that a slip from Q1 2027 to mid/late 2027 can still resolve Yes.

Rough decomposition:

• Chance Haven-1 launches by end-2027: around the high-50s to low-60s.
• Conditional on launch, chance humans visit it by end-2027: around mid-60s.
• That puts Haven-1 alone around the high-30s.
• Add a small amount for other stations or favorable resolution ambiguity.

That yields a forecast in the low-40s, not a coin flip.

Shorter/longer checkpoints I’d use:

• By end-2026: very low, since Haven-1 is already delayed to 2027.
• By mid-2027: meaningful but still well below even odds.
• By end-2028: better than even, because additional slippage still leaves time.

Key assumptions most likely to matter:

1. Haven-1 does not slip past 2027.
   Failure chance: about 40.
   If this fails, the market probably resolves No unless an unlikely alternative succeeds.
2. If Haven-1 launches, it can be commissioned and cleared for a crew visit quickly enough.
   Failure chance: about 35.
   This is the most underappreciated second-step risk.
3. No alternative station unexpectedly beats Haven-1 or qualifies via an ambiguous interpretation.
   Failure chance: about 15.
   This is the main upside tail to a No-centered base case.

Given my own tendency toward overconfidence, I shade slightly downward from an initial mid-40s instinct.
