Key Context on Timelines and Developments (as of June 2026):
Haven-1 by Vast is the most advanced new commercial space station project, with a firm Q1 2027 launch target on a Falcon 9. Uncrewed commissioning could occur in mid-2026-equivalent windows if earlier schedules held, but the latest update pushes this into 2027; a first crewed visit (via Crew Dragon) is possible shortly afterward but not guaranteed within the year due to safety and integration requirements.[2][1]

Orbital Reef and Starlab remain in earlier design or pre-launch phases with no crewed visit dates before late 2027 or beyond; Starlab’s target has slipped to 2029. NASA’s consideration of Starship-based concepts has not yielded concrete near-term habitat plans. No other new habitats show credible paths to human visits by end-2027. Recent updates (especially Vast’s January 2026 announcement) represent the primary movement toward a potential positive resolution, though crewed timing carries uncertainty.

Analysis: New Space Habitat Visited by Humans Before End of 2027

Current Situation Assessment

Based on the research from June 2026, the landscape for commercial space habitats is as follows:

Haven-1 (Vast) – Most Advanced Candidate

• Integration began January 2026
• Launch target: NET Q1 2027 on Falcon 9
• First crewed mission (Vast-1): 30-day mission with four astronauts planned
• Crew transport: SpaceX Crew Dragon
• Key caveat: “First crewed mission timing remains flexible, potentially weeks after launch or much later, pending safety confidence”

Orbital Reef (Blue Origin) – In design/development phase with no firm launch or crewed timeline before late 2027

Starlab – Launch slipped to 2029 (from earlier 2027/2028 targets)

SpaceX Starship as station – No concrete near-term habitat plans

Timeline Analysis

From today (June 10, 2026) to resolution (December 31, 2027): ~19 months

For a crewed visit to occur:

1. Haven-1 must launch successfully (target Q1 2027)
2. Station must deploy and function properly
3. Uncrewed commissioning must complete
4. Safety validation must be satisfactory
5. Crew Dragon mission must be scheduled and executed

If launch occurs March 2027, approximately 9 months remain in 2027 for crewed visit.

Key Probability Factors

P(Haven-1 launches by Dec 2027): ~75%

• Q1 2027 target could slip; space programs frequently delay 6-12 months
• Integration progress is positive, but testing/validation phases remain

P(Station operational after launch): ~85%

• Modern spacecraft generally reliable
• New designs carry higher risk

P(Crewed visit occurs in 2027 given successful launch):

• If Q1 launch: ~40-45% (9 months for commissioning + crew mission)
• If Q2-Q3 launch: ~25% (less time available)
• If Q4 launch: ~10% (minimal time for crewed follow-up)
• Weighted average assuming launch timing distribution: ~35%

Critical Assumptions Analysis

1. Haven-1 launches in 2027: If this fails (20-25% chance), the question almost certainly resolves No, as no other habitat is close.
2. Post-launch commissioning allows crewed visit in same calendar year: The “much later” qualifier in research suggests ~50-60% chance crewed visit slips to 2028.
3. No major technical failures: First-of-kind commercial station has elevated risk (~15% chance of mission-critical issues).

Combined Probability Calculation

P(Yes) = P(launch by end 2027) × P(operational|launch) × P(crewed visit same year|operational)
= 0.75 × 0.85 × 0.35
= ~22%

Adding small probability for other unexpected developments: +3%
Total: ~25%

Historical Context & Calibration

• Space programs historically experience significant delays
• No precedent for commercial space station crewed visits (novel situation)
• Base rate consideration: historically ~35% of forecasting questions resolve positively
• Personal tendency toward overconfidence warrants downward adjustment

The “pending safety confidence” language in the research strongly suggests Vast prioritizes safety over aggressive timelines, making a 2028 crewed visit more likely than 2027.

Probability: 25%
The extracted probability is: 25%

Reasoning Through the Question

Question: Will any new space habitat be visited by humans before the end of 2027?

Key Timeline: Today is June 10, 2026 → Resolution: December 31, 2027 (~19 months)

Candidate Habitats Assessment

1. Haven-1 (Vast) – Most Likely Candidate

• Currently in integration phase (as of Jan 2026)
• Launch target: Q1 2027 on Falcon 9
• Already slipped from mid-2026 to Q1 2027
• First crewed mission (Vast-1): “weeks after launch or much later”
• Uses proven SpaceX Crew Dragon for crew transport
• NASA has been supporting development with successful testing milestones

1. Orbital Reef (Blue Origin) – Not a 2027 candidate

• Still in design/development phase with no firm crewed timeline

1. Starlab (Voyager) – Not a 2027 candidate

• Launch slipped to NET 2029

1. SpaceX Starship station – Not a 2027 candidate

• No concrete plans; focus remains on Artemis/satellite deployment

Probability Analysis for Haven-1

Launch Timing Scenarios:

• Launch by Q1 2027 (on schedule): ~50% (space projects frequently slip; already delayed once)
• Launch by Q2 2027: ~65%
• Launch by end of 2027: ~75%

Crewed Mission Timing (given launch):
The “weeks after launch” statement is encouraging, but “much later” caveat adds uncertainty.

• If launched Q1 2027: ~50% chance of crewed visit by year-end (9-12 months for commissioning)
• If launched Q2 2027: ~35% chance (6-9 months)
• If launched Q3 2027: ~15% chance (3-6 months)
• If launched Q4 2027: ~5% chance (very tight)

Combined Calculation:

• P(launch Q1) × P(crew|Q1) = 0.50 × 0.50 = 25%
• P(launch Q2 only) × P(crew|Q2) = 0.15 × 0.35 = 5.25%
• P(launch Q3 only) × P(crew|Q3) = 0.05 × 0.15 = 0.75%
• P(launch Q4 only) × P(crew|Q4) = 0.05 × 0.05 = 0.25%
• P(other habitat surprise): ~2%

Subtotal: ~33%

Critical Assumptions to Question

1. Launch schedule holds within 2027 (~75% confident)

• If wrong (no 2027 launch): Resolution becomes nearly impossible
• Failure probability: ~25%

1. Rapid post-launch commissioning is feasible (~50% confident for quick turnaround)

• Commercial stations are unprecedented; commissioning could take longer
• If extended commissioning needed: Probability drops significantly
• Failure probability: ~40%

1. No major technical/safety issues delaying crew (~70% confident)

• New platform with first-time systems
• Failure probability: ~30%

Historical Context & Base Rates

• Space development projects historically experience significant delays
• Commercial space has accelerated timelines (SpaceX achievements)
• ISS took years before routine crew visits, though modern technology is more mature
• Historical positive resolution rate for forecasting questions: ~35%

Adjustments

• Compensating for typical overconfidence bias
• The relatively short timeline (19 months) limits how much could be achieved
• Proven Crew Dragon reduces crew transport risk
• Strong NASA partnership is a positive signal

Probability: 32%
The extracted probability is: 32%

Analysis: New Space Habitat Human Visit by End of 2027

Key Projects Assessment

Haven-1 (Vast) – Most Viable Candidate

• Current Status: In integration phase as of January 2026
• Launch Target: Q1 2027 (already slipped from mid-2026)
• Crewed Mission: Vast-1 planned for 30-day mission with 4 astronauts via Crew Dragon
• Critical Note: Research indicates crewed timing is “flexible” – could be “weeks after launch” OR “much later pending safety confidence”

Other Projects

• Orbital Reef (Blue Origin): Still in design/development phase, no crewed timeline before late 2027
• Starlab: Slipped to NET 2029, not relevant
• SpaceX Starship as station: No concrete near-term plans

Timeline Analysis

Current date: June 10, 2026
Resolution date: December 31, 2027
Time remaining: ~19 months

For resolution YES, Haven-1 must:

1. Launch successfully (targeted Q1 2027)
2. Complete uncrewed commissioning/validation
3. Receive crewed visit via Crew Dragon

Critical Assumptions & Failure Probabilities

1. Haven-1 launches by mid-2027: ~35% chance of NOT happening

• Space projects frequently slip; already delayed once
• However, integration has begun and progress is documented

1. Successful commissioning within reasonable timeframe: ~30% chance of significant delays

• First-of-kind commercial station with inherent risks
• NASA support helps but doesn’t guarantee timeline

1. Crewed mission occurs in 2027 after successful commissioning: ~40% chance of NOT happening

• “Flexible” timing language suggests no firm commitment
• Safety requirements are stringent for new habitats
• If launch slips to mid-2027, timeline becomes very tight

Probability Calculation

Using conditional probabilities:

• P(launch by mid-2027) ≈ 55%
• P(successful commissioning in ~5 months | launch) ≈ 60%
• P(crew visit in remaining time | commissioning) ≈ 60%

Combined: 0.55 × 0.60 × 0.60 ≈ 20%

Accounting for alternative scenarios (later 2027 launches with tighter timelines):

• Q3 2027 launch with rushed crew visit: adds ~3-4%
• Other projects achieving unexpected progress: adds ~1-2%

Adjustments

• Historical forecaster overconfidence: slightly reduce estimate
• Base rate consideration: ~35% of questions resolve positively historically
• Space industry track record: delays are common, but SpaceX Crew Dragon is proven
• The “flexible” language regarding crewed timing is a significant red flag

Alternative Timeline Considerations

• P(crewed visit by Q2 2027): ~5%
• P(crewed visit by Q4 2027): ~22%
• P(crewed visit by Q4 2028): ~55%

The probability is not evenly distributed; it’s concentrated in late 2027 and 2028.

Summary

The most plausible path to resolution is Haven-1 launching in Q1-Q2 2027, completing commissioning over several months, and hosting a crewed Crew Dragon mission by late 2027. However, the “flexible” crewed timeline, history of delays in space projects, and the unprecedented nature of commercial space stations all suggest meaningful uncertainty. Other projects have no credible path to crewed visits by end of 2027.

Probability: 22%
The extracted probability is: 22%

GPT Binary response:

The positive case is overwhelmingly a Haven-1 case.

Why I’m not higher:

• The strongest, most recent source is Vast’s January 2026 update putting Haven-1 at a Q1 2027 launch target and into integration. That is meaningful progress, and it makes Haven-1 a real candidate.
• But “launch target” for a first-of-its-kind private crew-capable habitat is not the same as a likely operational date. Spaceflight schedules for novel human-spaceflight hardware slip a lot, and this project still needs not just launch, but successful on-orbit checkout and a crewed visit via Dragon before 2027 ends.
• The other named candidates are much weaker. Orbital Reef still looks developmental, Starlab appears pushed to 2029, and Starship-as-station remains speculative rather than a concrete pre-2028 program.

Source weighting:

• Highest weight: Vast January 2026 official update, since it is recent and directly about the leading candidate.
• High weight: reporting summarizing that first crew timing is flexible and could be delayed pending safety confidence.
• Medium weight: NASA’s 2025 Haven-1 subsystem-testing support, which is a genuine credibility boost but stale relative to schedule risk.
• Medium-high weight for ruling out alternatives: NASA/SpaceNews material on Orbital Reef and Starlab showing they are not close enough for a 2027 crewed visit.
• Low weight: Wikipedia, used only as corroboration.

My rough scenario tree:

• Haven-1 launched and visited by humans by end of 2027: about 36%
• Any other pathway to a new human-visited habitat by end of 2027: about 3%

That gives a total near 39%.

Why Haven-1 is still below even odds:

1. Launch schedule risk remains large. A Q1 2027 target announced in early 2026 is plausible, but first-flight space hardware often slips by several quarters or more.
2. Even after launch, the crewed visit is not automatic. The station may need commissioning time, fixes, or more confidence before accepting people.
3. The resolution window is calendar-bound. A launch in late 2027 is much less useful than one in early 2027 because even a modest post-launch delay can push the first human visit into 2028.

Timeline sanity check:

• By end of 2026: about 1%
• By mid-2027: about 9%
• By end of 2027: about 39%
• By end of 2028: about 63%

Key assumptions most likely to move this forecast:

1. Assumption: Haven-1 launches by late 2027.

• Chance this assumption is wrong: about 45%
• Impact: If wrong, the market is probably No unless an unexpected alternative appears.

1. Assumption: If Haven-1 launches in time, it can host a crew within the same year.

• Chance this assumption is wrong: about 35%
• Impact: A successful launch could still fail to resolve Yes if commissioning or certification takes longer than expected.

1. Assumption: No surprise alternative habitat reaches a human visit first.

• Chance this assumption is wrong: about 10%
• Impact: This is the main upside tail for a Yes beyond Haven-1, but current evidence for such a surprise is weak.

Bottom line: there is now a credible path to Yes, but it is still more likely than not that the combination of schedule slip plus post-launch caution pushes the first visit beyond 2027.

Probability: 39%

The extracted probability is: 39%

GPT Binary response:

The base case is still No, but not overwhelmingly so.

Why:

• Haven-1 is the only credible near-term path.
  The provided research strongly suggests Vast’s Haven-1 is the only project with a realistic chance inside the window. As of January 2026 it had entered integration with a Q1 2027 launch target. That is meaningful progress, and it uses relatively mature infrastructure around it: Falcon 9 for launch and Crew Dragon for crew transport. That reduces risk relative to projects that need both a station and a new crew transport system.
• But “launch in 2027” is not the same as “humans visit by end-2027.”
  The key uncertainty is not just whether Haven-1 reaches orbit, but whether it is considered safe enough for a crewed visit in time. The research explicitly notes the first crewed mission could be weeks after launch or much later depending on confidence and validation. That matters a lot. Even if Haven-1 launches in 2027, a cautious checkout period could push the first human visit into 2028.
• Commercial space hardware schedules slip a lot.
  A January 2026 target of Q1 2027 is only moderately reassuring. Space habitats are hard, and crew-rating anything is harder. A slip from Q1 2027 into late 2027 or 2028 would be unsurprising. Since the resolution date is end-2027, even a moderate delay is often fatal to a Yes outcome.
• The alternatives look weak.
  Orbital Reef appears too early in development for a crewed visit by 2027.
  Starlab has reportedly slipped to no earlier than 2029.
  NASA/SpaceX Starship-as-station remains conceptual, not operational on this timescale.
  So this forecast is basically a Haven-1 forecast plus a small residual from “something unexpected.”

A rough decomposition:

• Haven-1 launched by end-2027: around 60–65%
• Crewed visit by end-2027 conditional on launch by then: around 45–55%
• That gives Haven-1 roughly 27–36% on its own
• Add a few points for all other paths combined

Shorter/longer timeline calibration:

• By end-2026: essentially near zero
• By mid-2027: still low, around 8–12%
• By end-2027: materially higher because Haven-1 has a real shot
• By end-2028: much higher than this market, because a 2027 slip still leaves a live path

Key assumptions most likely to be wrong and most impactful:

1. Haven-1’s current schedule is roughly credible.
   Chance this assumption is wrong: about 45%
   If wrong, the probability drops sharply.
2. If Haven-1 launches in 2027, crew will visit within the same calendar year.
   Chance this assumption is wrong: about 50%
   This is the biggest bottleneck after launch timing.
3. No other habitat meaningfully enters the picture before end-2027.
   Chance this assumption is wrong: about 15%
   If wrong, it raises the forecast, but probably only modestly.

Overall, the event is plausible but still more likely not to happen in time. The strongest argument for Yes is that Haven-1 is simpler and more advanced than the other candidates. The strongest argument for No is that first-of-kind orbital habitats with human occupancy almost always take longer than optimistic schedules, and this market needs not just launch but a human visit before a hard deadline.

Reasoning Rationale

1. Deconstruction of the Question

The core of the question is to determine the probability that humans will visit a new space habitat (not the ISS or Tiangong) between today (June 10, 2026) and December 31, 2027. This requires evaluating the status, timelines, and potential risks of all candidate projects.

2. Analysis of Candidates

Based on the provided research and current public information, the viable candidates for a new space habitat are:

• Haven-1 (Vast): This is overwhelmingly the leading candidate.
• Orbital Reef (Blue Origin / Sierra Space): Multiple sources from 2021-2022 cite a 2027 operational date, but more recent reporting from late 2023 indicates issues between the partners and a lack of project momentum, suggesting this timeline is no longer credible. It remains in the design and testing phase.
• Starlab (Voyager / Airbus): Initial plans targeted a 2027 launch, but this has since slipped significantly. Recent reporting indicates a launch later in the decade, with some sources mentioning 2028 or 2029.
• Axiom Station: The first module is now slated to launch in 2028 and will initially attach to the ISS, not function as a new, independent habitat within the resolution timeframe.
• SpaceX Starship as a station: This remains a conceptual idea with no firm development plans or timelines for use as a dedicated LEO habitat before the resolution date.

This analysis narrows the focus of the question almost entirely to a single project: Will humans visit Vast’s Haven-1 by the end of 2027?

3. Forecasting the Haven-1 Timeline

The path to a “Yes” resolution for Haven-1 involves two critical, sequential steps:

1. Successful launch of the Haven-1 module in 2027.
2. Successful launch and docking of the first crewed mission (Vast-1) before December 31, 2027.

Step 1: Probability of a 2027 Launch

• The official schedule is “no earlier than Q1 2027,” which was a delay from a previous 2026 target. This “NET” phrasing in aerospace is notoriously optimistic.
• Vast is making tangible hardware progress, with the primary structure fully welded and integration of subsystems underway as of early 2026.
• However, the history of complex, first-of-their-kind aerospace projects is defined by delays. The base rate for such projects meeting their initial “NET” dates is low. A slip of 6-12 months from the target is common.
• Assessment: I estimate a 50% probability that Haven-1 will successfully launch at some point within the 2027 calendar year. This is a coin-flip chance, acknowledging both the real progress being made and the high historical probability of further delays pushing the launch into 2028.

Step 2: Probability of a 2027 Crew Visit (Conditional on a 2027 Launch)

• This is not a simple probability; it heavily depends on when in 2027 the launch occurs.
• After launch, an on-orbit commissioning phase is required to test all systems and ensure the station is safe for crew. Vast’s CEO has stated this verification could take “as early as two weeks… as late as any time within three years.” While “two weeks” is extremely optimistic, the key takeaway is the high degree of uncertainty and the emphasis on safety, driven by their partner SpaceX.
• A launch in H1 2027 (Jan-Jun) would leave 6-12 months for this checkout period. This provides a plausible, albeit challenging, window for a follow-on crew mission within the same year.
• A launch in H2 2027 (Jul-Dec) dramatically shortens this window. A launch in Q4 makes a 2027 crew visit nearly impossible, as a 1-3 month checkout for a brand-new station type is highly improbable.

4. Calculation and Synthesis

To formalize the forecast, I will break down the 50% launch probability and apply conditional probabilities for the crewed visit.

• P(Launch in 2027): 50%
  • Let’s distribute this probability: It’s more likely to slip later into the year.
    • P(Launch in H1 2027): 20%
    • P(Launch in H2 2027): 30%
• P(Crew Visit in 2027 | Launch Date):
  • P(Crew Visit | H1 Launch): 60%. (A 40% chance of a slip into 2028 due to commissioning issues, even with a 6+ month window).
  • P(Crew Visit | H2 Launch): 20%. (An 80% chance of a slip into 2028 due to the compressed timeline).
• Total Probability Calculation:
  • Path 1 (H1 Launch & Visit): P(Launch H1) * P(Visit | H1) = 0.20 * 0.60 = 0.12
  • Path 2 (H2 Launch & Visit): P(Launch H2) * P(Visit | H2) = 0.30 * 0.20 = 0.06
  • Total “Yes” Probability = 0.12 + 0.06 = 0.18

5. Final Review and Key Assumptions

This 18% forecast is centered on the following assumptions:

• Assumption 1: No other candidate (Orbital Reef, Starlab) will dramatically accelerate its timeline. The probability of this assumption being incorrect is very low, given their current stated schedules and development status.
• Assumption 2: Vast will not encounter a catastrophic failure or multi-year delay before 2028. My 50% probability of launch in 2027 already accounts for a high chance of a “normal” slip into 2028. This assumption is about a more severe, unexpected setback.
• Assumption 3: The post-launch commissioning phase will be challenging but not insurmountable within the given timeframe. My model assigns a high likelihood (80%) that an H2 launch pushes the crew mission into 2028, reflecting the expected caution and difficulty of this phase.

The 18% figure reflects that a “Yes” resolution is a plausible long shot. It requires Vast’s Haven-1 to navigate the final, difficult stages of development and commissioning with only minor delays, a significant challenge for any novel aerospace project.

The extracted probability is: 18%

GPT Binary response:

This is mostly a Haven-1 question.

Why:

• Haven-1 has the only cited, concrete path to a human visit by the end of 2027: integration has started, launch is targeted for Q1 2027, and the concept of operations is a Crew Dragon visit after launch.
• Orbital Reef still looks like a design/development program, not an operational 2027 destination.
• Starlab has slipped far enough that it is effectively out for this window.
• A Starship-based station remains more of a concept than a scheduled program for this timeframe.

So the right way to think about this is:

1. What is the chance Haven-1 launches in time?
2. Conditional on launch, what is the chance people actually visit it before year-end 2027?
3. Add a small residual for all other paths.

Key considerations:

• Positive evidence
• Haven-1 is not vaporware anymore; there is real hardware progress.
• It benefits from using relatively mature transport infrastructure: Falcon 9 + Crew Dragon.
• The resolution only requires a visit, not long-term successful operation.
• Private crews may accept somewhat more schedule and program flexibility than a purely NASA-led mission.
• Negative evidence
• This is still a first-of-kind crewed habitat. Those slip a lot.
• Vast already moved from a 2026 target to Q1 2027; that is a warning sign, not a one-off detail.
• The hardest part is not just launching the module; it is getting through integrated testing, on-orbit checkout, and enough confidence to put humans aboard.
• Because almost all of the probability mass is concentrated in one project, there is little diversification. A Haven delay likely means a No.

My rough decomposition:

• Haven-1 visited by humans by end-2027: about 31%
• Any other qualifying habitat: about 4%
• Combined after overlap adjustment: about 34%

Timeline check:

• By end of 2026: essentially negligible, around 1%
• By mid-2027: still low, around 7%
• By end of 2027: about 34%
• By end of 2028: materially higher, roughly 60%+, because the modal miss here is “slips by about a year,” not cancellation

The assumptions that matter most:

1. Haven-1 is the only serious pre-2028 candidate.
   Chance this is wrong: about 15%. If wrong, odds rise somewhat.
2. Vast’s Q1 2027 target is still optimistic.
   Chance this is wrong: about 40%. If they execute unusually well, odds rise a lot.
3. Even after launch, crewed visitation is not immediate or guaranteed.
   Chance this is wrong: about 30%. If commissioning is quick, odds rise materially.

Net: there is a real path to Yes, but the default case is still No because the window is short and the path is narrow.

Reasoning Through the Question

Question: Will any new space habitat be visited by humans before the end of 2027?

Key Timeline: Today is June 10, 2026 → Resolution: December 31, 2027 (~19 months)

Candidate Habitats Assessment

1. Haven-1 (Vast) – Most Likely Candidate

• Currently in integration phase (as of Jan 2026)
• Launch target: Q1 2027 on Falcon 9
• Already slipped from mid-2026 to Q1 2027
• First crewed mission (Vast-1): “weeks after launch or much later”
• Uses proven SpaceX Crew Dragon for crew transport
• NASA has been supporting development with successful testing milestones

1. Orbital Reef (Blue Origin) – Not a 2027 candidate

• Still in design/development phase with no firm crewed timeline

1. Starlab (Voyager) – Not a 2027 candidate

• Launch slipped to NET 2029

1. SpaceX Starship station – Not a 2027 candidate

• No concrete plans; focus remains on Artemis/satellite deployment

Probability Analysis for Haven-1

Launch Timing Scenarios:

• Launch by Q1 2027 (on schedule): ~50% (space projects frequently slip; already delayed once)
• Launch by Q2 2027: ~65%
• Launch by end of 2027: ~75%

Crewed Mission Timing (given launch):
The “weeks after launch” statement is encouraging, but “much later” caveat adds uncertainty.

• If launched Q1 2027: ~50% chance of crewed visit by year-end (9-12 months for commissioning)
• If launched Q2 2027: ~35% chance (6-9 months)
• If launched Q3 2027: ~15% chance (3-6 months)
• If launched Q4 2027: ~5% chance (very tight)

Combined Calculation:

• P(launch Q1) × P(crew|Q1) = 0.50 × 0.50 = 25%
• P(launch Q2 only) × P(crew|Q2) = 0.15 × 0.35 = 5.25%
• P(launch Q3 only) × P(crew|Q3) = 0.05 × 0.15 = 0.75%
• P(launch Q4 only) × P(crew|Q4) = 0.05 × 0.05 = 0.25%
• P(other habitat surprise): ~2%

Subtotal: ~33%

Critical Assumptions to Question

1. Launch schedule holds within 2027 (~75% confident)

• If wrong (no 2027 launch): Resolution becomes nearly impossible
• Failure probability: ~25%

1. Rapid post-launch commissioning is feasible (~50% confident for quick turnaround)

• Commercial stations are unprecedented; commissioning could take longer
• If extended commissioning needed: Probability drops significantly
• Failure probability: ~40%

1. No major technical/safety issues delaying crew (~70% confident)

• New platform with first-time systems
• Failure probability: ~30%

Historical Context & Base Rates

• Space development projects historically experience significant delays
• Commercial space has accelerated timelines (SpaceX achievements)
• ISS took years before routine crew visits, though modern technology is more mature
• Historical positive resolution rate for forecasting questions: ~35%

Adjustments

• Compensating for typical overconfidence bias
• The relatively short timeline (19 months) limits how much could be achieved
• Proven Crew Dragon reduces crew transport risk
• Strong NASA partnership is a positive signal

Probability: 32%
