Perplexity response:

{think}
The user is asking me to search for and analyze information relevant to the forecast question: “Will any new space habitat be visited by humans before the end of 2027?”

The background mentions:

Haven-1 (most likely)
Orbital Reef (Blue Origin)
Starlab (Voyager Technologies)
SpaceX Starship (NASA considering as space station)

The current date is May 13, 2026. This means we’re about 7 months away from the end of 2027, so we’re looking at roughly an 18-month window.

I need to search for recent information about:

Haven-1 status and launch timeline
Orbital Reef status and launch timeline
Starlab status and launch timeline
SpaceX Starship as space station status
Any other emerging space habitats

The resolution sources provided are:

https://www.blueorigin.com/destinations (Orbital Reef)
https://voyagertechnologies.com/starlab/ (Starlab)
https://www.space.com/nasa-considering-spacex-starship-space-station

I should look for:

Current development status of each habitat
Expected launch dates
Expected human visitation dates
Any recent delays or accelerations
Technical readiness assessments

However, I notice the search results provided to me are about:

Baby beavers livestream
Space station Wikipedia article
ABQ BioPark renovations
Silverlens gallery

These don’t directly address the question about new space habitats. This seems to be placeholder/random search results.

Since I’m instructed to provide a detailed rundown and since these search results don’t contain relevant information about the specific space habitats mentioned in the question, I need to acknowledge this and explain what information I would need to gather to answer this effectively.

Let me think about what the superforecaster would need to know:

Haven-1 (Axiom) – This is likely the nearest-term candidate

Need to determine current development status, launch schedule, and when the first crewed docking with the ISS is expected
The key timing question is whether it will be deemed “visited” by humans within the 18-month window

Orbital Reef (Blue Origin) – Depends critically on New Glenn development

Must track New Glenn’s launch timeline since it’s a prerequisite for Orbital Reef deployment
Need Blue Origin’s construction and operational readiness schedule for crewed missions

Starlab (Voyager/Nanoracks/Thales) – Commercial space station concept

Should assess development progress, funding status, and launch timeline
Evaluate technical readiness and any recent milestones or setbacks

SpaceX Starship – NASA considering as potential space station replacement

Need to track NASA’s decision timeline and SpaceX’s readiness for crewed operations in this timeframe
This remains highly speculative given current development stage

I need to clarify my actual task here. The search results provided don’t align with the question about new space habitats being visited by humans before end of 2027. I should acknowledge this mismatch and outline what information would actually be relevant to address this forecast question.

My role is to prepare research context for forecasting, so I need to identify the key projects and timelines that matter. Based on what I know through April 2024, projects like Axiom’s Haven-1 habitat and potential commercial space station developments would be central to answering whether any new habitat gets human visitors by 2027. I should map out these specific initiatives, their expected launch windows, and any recent developments that affect their feasibility. I need to reconsider what’s being asked here. The user wants 10 citations, but the search results provided don’t address the actual question about space habitat timelines. This seems like they’re showing me a format example rather than giving me relevant sources to work with.

Since I can’t perform real-time searches and my knowledge cuts off in April 2024, I should clarify what information I can actually provide. At that point, Haven-1 was targeting a 2025-2026 launch window with crewed docking to follow, while Orbital Reef remained dependent on New Glenn’s development status. Starlab was progressing through design phases with Nanoracks and Thales. I’d need to identify which sources would have the most current updates on these projects’ progress and timelines through 2027.

Research Brief: New Space Habitat Human Visitation Before End of 2027

Planning Analysis

To effectively evaluate whether humans will visit any new space habitat before end of 2027 (approximately 19 months from the specified date of May 13, 2026), I need to research:

Haven-1 (Axiom Space): Current docking status with ISS, crewed mission schedules, and any delays
Orbital Reef (Blue Origin): New Glenn launch timeline (critical prerequisite), habitat construction status
Starlab (Voyager/Nanoracks/Thales): Development phase, funding status, launch readiness
SpaceX Starship: Current status of NASA agreements for station use, technical readiness
Recent industry developments: Any new habitat projects or accelerated timelines
Regulatory/certification status: What approvals are needed for crewed operations
Launch cadence: Availability of crew vehicles and launch windows

Critical Information Gap

I must note: My knowledge base extends through April 2024, and you’ve specified the current date as May 13, 2026. I cannot provide actual real-time data from May 2026. To provide truly current information for your forecast, you would need to:

Check Axiom Space’s latest investor updates and NASA docking schedules
Review Blue Origin’s New Glenn development status
Access recent announcements from Nanoracks/Voyager Technologies
Monitor official NASA and SpaceX statements

What Would Be Most Relevant to Research (as of April 2024 baseline knowledge):

Primary Candidates by Likelihood:

Haven-1 (Axiom Space) – Highest probability candidate

Status as of April 2024: Scheduled to launch and dock with ISS in 2025-2026
Key factor: This would likely be the first new habitat to receive crewed visits
Critical questions: Has launch occurred? Have crewed docking missions already happened?

Orbital Reef (Blue Origin) – Medium probability, time-constrained

Status as of April 2024: Contingent on New Glenn launcher (not yet flown)
Major dependency: New Glenn must launch, then habitat assembly and operations testing
Timeline concern: 19 months may be insufficient if New Glenn hasn’t launched yet

Starlab (Voyager/Nanoracks) – Lower probability for 2027 deadline

Status as of April 2024: Still in development phase, targeting 2028-2029 operations
Likely too late to meet end-of-2027 resolution

SpaceX Starship as Station – Lowest probability for hard deadline

Status as of April 2024: Conceptual stage, no concrete human operations timeline established

Key Data Points That Would Be Critical as of May 2026:

Haven-1 launch date (actual, not projected)
Haven-1 crewed mission schedule (first crew visit date)
New Glenn launch status (if not yet launched, orbital reef timeline becomes infeasible)
Orbital Reef construction status (percentage complete, quality gates passed)
Any regulatory delays or technical issues affecting each program
Starlab development phase and any unexpected acceleration

Sources That Should Be Checked:

For an accurate May 2026 forecast, you would want to verify:

Axiom Space official website and SEC filings (investor updates)
Blue Origin announcements on New Glenn and Orbital Reef progress
NASA’s International Space Station Program Office updates
Nanoracks/Voyager Technologies press releases
SpaceNews, Space.com, and industry publications for near-term developments
FAA/AST for any licensing or certification updates

Recommendation for the Superforecaster: To provide accurate probabilities, you’ll need to update this research with actual May 2026 data on the specific launch and crewed mission dates for each platform. The critical decision factor is likely to be Haven-1’s actual launch and docking schedule, as that appears to be the only candidate with realistic 2027 human visitation feasibility based on pre-2024 timelines.

Haven-1 by Vast Space remains the leading candidate for the first new space habitat, with recent January 2026 updates confirming entry into integration after primary structure completion, though launch delayed from mid-2026 to Q1 2027 on SpaceX Falcon 9.[1][2][5] The station’s roadmap lists Haven-1 for 2027 following a 2025 demo mission (Haven Demo, potentially flown by now as of May 2026), with the first crewed mission Vast-1 planned for four astronauts post-launch, though no precise docking date is specified beyond the operational phase in 2027.[11][6] This positions a human visit as feasible within 2027 if launch occurs early in Q1 and crew follows promptly, but integration risks could push timelines.

Orbital Reef, led by Blue Origin and Sierra Space, shows no firm commitments for 2026-2027 launches on its official page, remaining a Phase 1 concept from 2021 with NASA design progress noted in April 2025 human-in-the-loop testing.[7][12] A January 2026 analysis highlights dependency on New Glenn’s third mission (NET April 2026), with historical delays raising doubts on 2027 crewed operations.[8]

Starlab by Voyager Space (now Starlab Space JV) has slipped from 2027 to NET 2028-2029 launches, with a September 2025 manufacturing contract but official site lacking timeline details; recent NASA awards focus on ISS private missions NET 2028, not Starlab itself.[13][10]

NASA’s consideration of SpaceX Starship as a potential space station, per a July 2023 Space.com article, remains exploratory under CCSC-2 with no 2026-2027 commitments or updates in recent searches; Starship focuses on Artemis and Mars, not dedicated LEO habitat by end-2027.[14]

Axiom Station plans a 2027 Power and Propulsion Test Module ahead of Hab-1 in 2028, per March 2025 reports, with construction underway but human visits linked to full habitat assembly post-2027.[9][15] Other concepts like Max Space’s expandable habitats (April 2026 unveil) lack launch dates before 2028.[16]

No new space habitats have launched or been human-visiting as of May 13, 2026; Haven-1’s Q1 2027 launch represents the nearest-term progress, with January 2026 updates indicating forward movement despite the slip, while competitors face greater delays tied to rocket readiness and funding milestones. Expert commentary from Vast CEO emphasizes hardware readiness offsetting schedule shifts, and NASA continues supporting commercial LEO via CLD without endorsing specific 2027 achievers.

Analysis: New Space Habitat Human Visitation by End of 2027

Current Situation Assessment (May 13, 2026)

Based on the research provided, I need to evaluate each candidate space habitat:

Haven-1 (Vast Space) – Primary Candidate

Current Status: Entered integration phase as of January 2026 after completing primary structure welding
Launch Timeline: Slipped from mid-2026 to Q1 2027 (Falcon 9)
Crewed Mission: “Vast-1” with four astronauts planned post-launch, no specific date confirmed
Assessment: Only realistic candidate for 2027 human visitation

Other Candidates

Orbital Reef (Blue Origin): Dependent on New Glenn; no firm 2027 dates; unlikely for 2027
Starlab (Voyager): Slipped to 2028-2029 launch; eliminated for 2027
Axiom Space: PPTM in 2027, Hab-1 in 2028; human visits post-2027
SpaceX Starship Station: Exploratory only; no 2027 timeline

Probability Analysis

For Haven-1 to result in human visitation by end of 2027:

Launch Timing Distribution:

Q1 2027: 30%
Q2 2027: 25%
Q3 2027: 12%
Q4 2027: 8%
Doesn’t launch in 2027: 25%

Crewed Visit Probability (given launch timing):

Q1 launch → 9 months available → ~55% chance of crewed visit
Q2 launch → 6 months available → ~35% chance
Q3 launch → 3 months available → ~10% chance
Q4 launch → <3 months → ~3% chance

Weighted Calculation:

Q1: 0.30 × 0.55 = 0.165
Q2: 0.25 × 0.35 = 0.0875
Q3: 0.12 × 0.10 = 0.012
Q4: 0.08 × 0.03 = 0.0024
Haven-1 subtotal: ~27%

Other candidates/unexpected developments: ~3-5%

Critical Assumptions and Risk Assessment

Haven-1 launches in 2027 as planned (75% probability): Already slipped once; integration challenges cited. If pushed to 2028, resolution probability drops to ~5%.
Crewed mission follows launch within calendar year (~50% probability): On-orbit checkout typically takes months; regulatory approval for crewed operations could be lengthy.
No major accidents or technical failures (~85% probability): Any incident during launch or testing could cause multi-year delays.

Historical Context

Space station projects historically face significant delays (ISS, Commercial Crew programs)
Base rate consideration: Only ~35% of forecasting questions resolve positively
Commercial space station development is unprecedented territory with unknown unknowns

Additional Considerations

The research is from January 2026, meaning there’s been ~4 months of development since then that we don’t have visibility into
Haven-1’s transition to integration phase is encouraging but doesn’t guarantee timeline adherence
Competition between commercial providers could potentially accelerate timelines

Final Assessment

The question essentially hinges on whether Haven-1 can:

Complete integration and launch by mid-2027 at latest
Complete checkout and host a crewed mission within remaining months of 2027

Given historical patterns of space project delays, the already-delayed timeline, uncertainty around crewed mission scheduling, and my tendency toward overconfidence, I’ll moderate my estimate.

Probability: 32%
The extracted probability is: 32%

Analysis: New Space Habitat Human Visitation Before End of 2027

Current Situation Assessment (as of May 13, 2026)

Based on the research, I need to evaluate whether any new space habitat (not ISS or Tiangong) will receive human visitors by December 31, 2027 – approximately 19.5 months from now.

Candidate Assessment

Haven-1 (Vast Space) – Primary Candidate

Entered integration phase in January 2026 after completing primary structure welding
Launch delayed from mid-2026 to Q1 2027 (Falcon 9)
First crewed mission (Vast-1) with four astronauts planned “post-launch”
Currently the most advanced commercial station candidate
Integration has been ongoing for ~4.5 months with ~8-11 months until targeted launch

Orbital Reef (Blue Origin)

Dependent on New Glenn rocket (still facing delays)
No firm 2026-2027 launch commitments
Very unlikely to achieve human visit by end-2027

Starlab (Voyager Space)

Slipped from 2027 to NET 2028-2029
Effectively ruled out for this timeline

Axiom Station

Power and Propulsion Test Module targeted for 2027
Hab-1 module not until 2028
Human visits tied to full habitat assembly post-2027

SpaceX Starship as Station

Remains exploratory/conceptual
No concrete timeline for LEO habitat operations

Timeline Probability Analysis

For Haven-1 to resolve this question “Yes”:

Launch must occur in 2027 (currently targeting Q1)
Orbital checkout must complete
Crewed mission must dock before December 31, 2027

Launch Probability by Quarter:

P(Q1 2027 launch) = 35% (target, but slips common)
P(Q2 2027 launch) = 30% (reasonable slip scenario)
P(Q3-Q4 2027 launch) = 15%
P(2028+ launch) = 20%

Crewed Visit Probability Given Launch Timing:

If Q1 2027 launch: 65% chance crewed visit by EOY
If Q2 2027 launch: 45% chance crewed visit by EOY
If Q3-Q4 2027 launch: 15% chance crewed visit by EOY

Combined Calculation:

Q1 scenario: 35% × 65% = 22.75%
Q2 scenario: 30% × 45% = 13.5%
Q3-Q4 scenario: 15% × 15% = 2.25%
Total Haven-1: ~38.5%

Other candidates combined: ~3% (accounting for unlikely accelerations)

Critical Assumptions That Could Alter Forecast

Haven-1 integration proceeds without major technical issues (30% failure risk)

First-of-kind commercial station carries elevated risk
Could push launch to 2028 if significant problems emerge

Vast-1 crewed mission occurs within months of station launch (35% failure risk)

Extended checkout periods are common for new stations
Could push crewed visit into 2028 even with 2027 launch

No regulatory delays from NASA/FAA (20% failure risk)

Commercial space certification can be unpredictable

Historical Context

Space programs historically run late more often than on schedule
Commercial space has accelerated timelines but still faces typical engineering challenges
No commercial free-flying space station has ever hosted crew (novel event)

Final Assessment

Given that Haven-1 is in active integration, targeting Q1 2027 launch, with a crewed mission planned post-launch, there is a meaningful probability of success. However, the cascading requirements (on-time launch → successful checkout → crewed docking → all before EOY 2027) introduce substantial uncertainty.

The question essentially asks whether the space industry can execute an aggressive but not impossible timeline for a first-of-kind mission.

Accounting for:

Solid progress reported on Haven-1
Historical delays in space programs (~50% on-time rate)
Need for both launch AND crewed visit within 2027
Small contribution from other candidates
My historical overconfidence bias

Probability: 40%
The extracted probability is: 40%

Anthropic Binary response:

Analysis: New Space Habitat Human Visit Before End of 2027

Key Information Assessment

Based on the research from May 2026, I need to evaluate the likelihood of humans visiting any new space habitat (excluding ISS and Tiangong) by December 31, 2027.

Primary Candidate: Haven-1 (Vast Space)

Current Status (Jan 2026): Primary structure completed, entered integration phase
Launch Target: Q1 2027 on Falcon 9 (slipped from mid-2026)
Crewed Mission: Vast-1 planned post-launch with 4 astronauts
Critical Conflict: Wikipedia states “one year uncrewed then crewed” but Ars Technica reports “crewed mission shortly after launch”

Secondary Candidates (Very Low Probability)

Orbital Reef: Dependent on New Glenn, no firm 2027 dates, crewed operations likely post-2027
Starlab: Slipped to 2028-2029, manufacturing just contracted
SpaceX Starship as Station: Exploratory only, no concrete timeline
Axiom Station: Hab-1 planned for 2028, human visits after assembly

Probability Analysis

Critical Assumptions and Failure Probabilities:

Assumption 1: Haven-1 launches by mid-2027

Already delayed once (mid-2026 → Q1 2027)
Integration phase just started
Historical pattern: first-of-kind commercial space stations face additional delays
Probability of failure: ~35-40%

Assumption 2: Crewed mission follows within calendar year of launch

Contradictory information (“one year uncrewed” vs “shortly after”)
First commercial station would require extensive uncrewed checkout
NASA/regulatory scrutiny for human safety
Probability this assumption fails: ~50-55%

Assumption 3: No technical/safety issues prevent crewed operations

Unprecedented commercial habitat operation
Probability of failure: ~20-25%

Timeline Calculation:

Resolution window: 19.5 months from May 13, 2026
For 2027 crewed visit: Launch must occur by ~Q2 2027, crewed mission must follow within 6-9 months
If “one year uncrewed” is accurate and launch is Q1 2027 → crewed visit = Q1 2028 (MISS)
If “shortly after” is accurate (3-6 months) → Q3-Q4 2027 visit possible

Combined Probability:

P(Haven-1 launches by Q2 2027) × P(crewed follows within 2027) × P(no showstoppers)
~60% × ~45% × ~80% ≈ 22%

Adding small probability for other stations or surprise developments: +3%

Base Rate Consideration:

No commercial space station has ever been visited by humans
Space project delays are common
Historical positive resolution rate ~35%
First-of-kind achievements rarely hit initial timelines

Adjustments:

Upward: 19.5 months is significant runway; Vast appears highly motivated; SpaceX launch reliability high
Downward: Conflicting timeline info; already delayed once; unprecedented milestone; my historical overconfidence bias

Final Assessment

The most realistic path to resolution is Haven-1 launching early 2027 followed by a crewed Vast-1 mission in late 2027. However, the contradictory information about uncrewed checkout period (1 year vs “shortly after”) creates substantial uncertainty. If the year-long uncrewed period holds and launch is Q1 2027, the crewed visit would fall in Q1 2028—just missing resolution.

Given the single viable candidate, already-delayed timeline, conflicting operational plans, and first-of-kind nature of this achievement, I assess moderate but not high probability.

Probability: 28%
The extracted probability is: 28%

Forecasting Rationale

To determine the probability of humans visiting a new space habitat before the end of 2027, I will analyze the timelines and technical readiness of the primary candidates. The resolution window closes on December 31, 2027, approximately 19.5 months from today’s date of May 13, 2026.

1. Candidate Assessment

A review of the provided research indicates there is only one candidate with a plausible, albeit challenging, path to meeting the deadline:

Haven-1 (Vast): This is the leading and effectively sole candidate. Research from January 2026 confirms the project has advanced to the integration phase. However, its launch was delayed from mid-2026 to “no earlier than Q1 2027” aboard a SpaceX Falcon 9. A crewed mission, Vast-1, is planned to follow “shortly after launch.” The success of this forecast hinges almost entirely on Haven-1’s schedule.
Orbital Reef (Blue Origin): This project’s timeline is contingent on the New Glenn rocket, which has a history of delays and, as of early 2026, has not yet had its first launch. The assembly of the station would require multiple successful New Glenn flights. This multi-year process makes a crewed visit by the end of 2027 extremely unlikely.
Starlab (Voyager/Starlab Space): This project has officially slipped, with a target launch now in the 2028-2029 timeframe. It is not a candidate for a 2027 resolution.
Axiom Station: Axiom’s roadmap indicates its first habitat module (Hab-1) is planned for a 2028 launch, with human visits to follow. Their 2027 activities are focused on a power/propulsion module, not a habitable one.
SpaceX Starship: NASA’s consideration of Starship as a station remains purely conceptual, with no development timeline aimed at a 2027 in-service date.

2. Modeling the Haven-1 Timeline

The forecast simplifies to the probability of Haven-1 launching, completing on-orbit commissioning, and receiving its first crew before December 31, 2027.

Launch Date: The “Q1 2027” target is optimistic. Major aerospace projects have a high base rate of delays. The project has already experienced a ~6-9 month slip. A further slip is probable. I estimate the following launch probabilities:
- H1 2027: 40%
- H2 2027: 40%
- 2028 or later: 20%
Commissioning Time: Following launch, the station must undergo extensive on-orbit checks before it is certified safe for humans. While “shortly after” is the goal, a prudent and realistic timeframe for a novel station from a new company is 3-6 months. I will use a 4-month average for this critical phase.
Success Scenarios & Probabilities:
1. Launch by August 2027: To allow for a 4-month commissioning period, the station must launch by the end of August 2027. The probability of this is P(H1) + P(July/Aug) = 40% + (2/6 * 40%) ≈ 53%.
2. No Critical Failures: The process is subject to failure. I assign a 2% chance of launch failure (based on Falcon 9’s record) and a 20% chance of a major anomaly during commissioning that would delay a crew visit beyond 2027. The probability of navigating both hurdles is (1 – 0.02) * (1 – 0.20) = 0.98 * 0.80 = 78.4%.

3. Final Calculation

The final probability is the product of the chance of launching in time and the chance of avoiding critical failures.

Probability = P(Launch on Time) * P(No Critical Failures)
Probability = 53% * 78.4% ≈ 41.5%

Key Assumptions & Risks:

Schedule Slippage: The biggest risk is further delay to the Haven-1 launch. My forecast is highly sensitive to this; a 6-month slip from today would drastically lower the probability. The 53% chance of launching “on time” is the most uncertain variable.
Commissioning Speed: The assumption of a 4-month checkout period is an estimate. Unforeseen issues could easily extend this, while exceptional success could shorten it. A longer period would invalidate later launch dates within 2027.

Given the high degree of uncertainty and the historical tendency of space projects to face delays, a forecast below 50% is warranted, even with a single promising candidate. The path to a “Yes” resolution is narrow and depends on near-perfect execution from Vast and its partners.

Analysis: New Space Habitat Human Visitation Before End of 2027

Current Situation Assessment (as of May 13, 2026)

Based on the research, I need to evaluate whether any new space habitat (not ISS or Tiangong) will receive human visitors by December 31, 2027 – approximately 19.5 months from now.

Candidate Assessment

Haven-1 (Vast Space) – Primary Candidate

Entered integration phase in January 2026 after completing primary structure welding
Launch delayed from mid-2026 to Q1 2027 (Falcon 9)
First crewed mission (Vast-1) with four astronauts planned “post-launch”
Currently the most advanced commercial station candidate
Integration has been ongoing for ~4.5 months with ~8-11 months until targeted launch

Orbital Reef (Blue Origin)

Dependent on New Glenn rocket (still facing delays)
No firm 2026-2027 launch commitments
Very unlikely to achieve human visit by end-2027

Starlab (Voyager Space)

Slipped from 2027 to NET 2028-2029
Effectively ruled out for this timeline

Axiom Station

Power and Propulsion Test Module targeted for 2027
Hab-1 module not until 2028
Human visits tied to full habitat assembly post-2027

SpaceX Starship as Station

Remains exploratory/conceptual
No concrete timeline for LEO habitat operations

Timeline Probability Analysis

For Haven-1 to resolve this question “Yes”:

Launch must occur in 2027 (currently targeting Q1)
Orbital checkout must complete
Crewed mission must dock before December 31, 2027

Launch Probability by Quarter:

P(Q1 2027 launch) = 35% (target, but slips common)
P(Q2 2027 launch) = 30% (reasonable slip scenario)
P(Q3-Q4 2027 launch) = 15%
P(2028+ launch) = 20%

Crewed Visit Probability Given Launch Timing:

If Q1 2027 launch: 65% chance crewed visit by EOY
If Q2 2027 launch: 45% chance crewed visit by EOY
If Q3-Q4 2027 launch: 15% chance crewed visit by EOY

Combined Calculation:

Q1 scenario: 35% × 65% = 22.75%
Q2 scenario: 30% × 45% = 13.5%
Q3-Q4 scenario: 15% × 15% = 2.25%
Total Haven-1: ~38.5%

Other candidates combined: ~3% (accounting for unlikely accelerations)

Critical Assumptions That Could Alter Forecast

Haven-1 integration proceeds without major technical issues (30% failure risk)

First-of-kind commercial station carries elevated risk
Could push launch to 2028 if significant problems emerge

Vast-1 crewed mission occurs within months of station launch (35% failure risk)

Extended checkout periods are common for new stations
Could push crewed visit into 2028 even with 2027 launch

No regulatory delays from NASA/FAA (20% failure risk)

Commercial space certification can be unpredictable

Historical Context

Space programs historically run late more often than on schedule
Commercial space has accelerated timelines but still faces typical engineering challenges
No commercial free-flying space station has ever hosted crew (novel event)

Final Assessment

The question essentially asks whether the space industry can execute an aggressive but not impossible timeline for a first-of-kind mission.

Accounting for:

Solid progress reported on Haven-1
Historical delays in space programs (~50% on-time rate)
Need for both launch AND crewed visit within 2027
Small contribution from other candidates
My historical overconfidence bias

Probability: 40%
