Perplexity response:

1. [1] “Is Voyager Space (VOYG) Poised for Lift-Off with NASA’s CLD Program” – a July 13, 2026 equity research article analyzing Voyager Space’s Starlab plans within NASA’s Commercial LEO Destinations program.[1] It reports Starlab is targeting a 2029 launch on SpaceX Starship with pressurized volume about 45% of the ISS US segment.[1] The article compares timelines for Starlab, Axiom’s ISS-attached modules (first module in 2027, independent station around 2028) and Vast’s Haven-1/Haven-2, noting Voyager’s schedule is later than some competitors for early human visits.[1]
2. [2] “Voyager completes purchase of Astrobotic; obtains $250 million credit line” – a July 13, 2026 analysis ranking five American space stations presently under development.[2] It describes Vast’s Haven-1 demo station as launching in 2027 for a three‑year period with at least four two‑week-long crewed missions, including a French astronaut, and notes preliminary astronaut-flight deals with multiple countries and biomedical companies.[2] The article states Vast has raised more than a billion dollars and already flown a small unmanned demo module, positioning Haven-1/Haven-2 as the current commercial front-runners for early human occupancy in low Earth orbit.[2]
3. [3] “ISS vai ter mais companhia. Primeira estação espacial privada pode chegar já em 2027” – a July 12, 2026 Portuguese-language report on private space stations, focusing on Vast’s Haven-1.[3] It explains that Haven-1 is designed to launch in the first quarter of 2027 on a SpaceX Falcon 9 and host up to four astronauts for missions of up to two weeks, with Crew Dragon providing transport, power and life-support during visits.[3] The station is described as offering about 45 m³ of habitable volume for microgravity research, manufacturing and Earth observation, potentially making it the first commercial space station to accompany the ISS.[3]
4. [5] “Vast’s Haven-1 in 2026: a 3D-printed space station preparing …” – a July 11, 2026 feature on Haven-1’s technical progress and schedule.[5] It notes Vast has slipped the launch from 2026 into early 2027, now targeting first-quarter 2027 and laying out a three-phase integration plan (thermal and life support, then avionics/navigation, then crew habitation and micrometeoroid protection) followed by environmental testing.[5] The article describes Haven-1’s mass (14,600 kg), dimensions and orbit, reiterates its four-astronaut, two-week mission profile, and mentions NASA’s description of the station plus NASA’s award of a separate private astronaut mission to the ISS in summer 2027 with SpaceX providing transport.[5]
5. [11] “Vast Delays Haven-1 Launch to 2027” – a July 9, 2026 commercial space news item covering the latest schedule for Haven-1.[11] It reports that Haven-1, once expected to launch in 2026, will now launch no earlier than Q1 2027 and cautions that it could be significantly longer before the station receives its first crew.[11] This piece emphasizes schedule risk on the crewed-visit timeline, framing Haven-1 as still the earliest commercial station but with growing uncertainty about when human occupancy will actually begin.[11]
6. [4] “SpaceLintech and StarLab Space sign agreement to secure space station payload space” – a July 14, 2026 Korean-language article about a commercial research agreement on Starlab.[4] It describes Starlab as a commercial space station being co-developed by Voyager Technologies and Airbus to replace the ISS after its planned end of mission around 2030, with internal space of roughly 450 m² and an expected launch in 2029.[4] The article highlights that the agreement secures future payload space for AI-based space medicine research, underscoring that Starlab is oriented toward the post‑2030 era rather than near-term human visits before 2027.[4]
7. [10] “SpaceLintech, US Starlab agreement… ‘Securing a space outpost'” – another July 14, 2026 Korean report on the same Starlab partnership.[10] It reiterates that Starlab is intended to replace the ISS after 2030 and that the agreement marks the first time a Korean private company has secured utilization space on a future commercial space station.[10] The story reinforces the 2030‑plus operational outlook for Starlab, confirming that its initial launch and human use are expected well after 2027.[10]
8. [6] “Russia sends American and two cosmonauts to space station with rare NASA chief visit” – a July 14, 2026 news report on a Soyuz crewed launch to the ISS.[6] It describes U.S. astronaut Anil Menon and two Russian cosmonauts launching aboard Soyuz MS‑29 for about eight months on the ISS, with both NASA and Roscosmos leadership attending.[6] The piece illustrates that NASA and partners continue to rely on the ISS for long-duration human spaceflight through at least April 2027, underscoring that the ISS remains the primary habitat in low Earth orbit over the forecast period.[6]
9. [7] “NASA astronaut and 2 cosmonauts blast off for an 8‑month …” – a July 14, 2026 detailed account of the same ISS mission.[7] It explains that Menon, Dubrov and Kikina will spend about 260 days aboard the ISS, with Russia extending typical stays from five–six months to eight months to reduce cargo shipments.[7] The article confirms the crew is scheduled to return around April 2027, reinforcing the ISS’s continued central role and timeline for human habitation.[7]
10. [8] “SpaceX to launch Starship again as next Artemis moon mission looms” – a July 13, 2026 report on Starship’s upcoming test flight and its role in NASA’s Artemis program.[8] It notes SpaceX is working toward a July 16 launch of the 13th Starship test, and that NASA needs Starship ready to reach space in 2027 for Artemis III, where it will serve as a lunar lander.[8] The piece emphasizes Starship’s developmental status and NASA’s focus on a lunar landing configuration, rather than its use as a near‑term orbital space station or habitat.[8]

Step‑by‑step information needs for this question

To support a forecast on “Will any new space habitat be visited by humans before the end of 2027?”, the key information needs are:

• Clear understanding of the resolution criteria: what counts as a “new space habitat,” and what qualifies as a “visit” by humans (e.g., docking and entry, not just flyby).
• Up‑to‑date schedules for each plausible candidate habitat:
• Vast’s Haven‑1 (and possibly Haven‑2).
• Orbital Reef (Blue Origin/Sierra Space).
• Starlab (Voyager Technologies/Airbus).
• Any credible concept of using SpaceX Starship as an orbital station/habitat.
• Other commercial LEO destinations under NASA’s CLD program (e.g., Axiom’s independent station), insofar as they could be operational with crew before end‑2027.
• Evidence of:
• Hardware readiness (manufacturing, integration, testing milestones).
• Launch contracts and target launch windows.
• Announced crewed missions (contracts with agencies or private customers, planned mission dates).
• Funding and program stability that affect schedule risk.
• Context on ISS and Tiangong operations, since these are excluded from resolution but set the benchmark for human LEO operations and might compete for launch/crew resources.[6][7]
• For Starship, specific milestones toward orbital flight reliability and any formal NASA or commercial plans to use Starship as a station or depot by 2027.[8]
• Any authoritative, official pages (e.g., Orbital Reef, Starlab, NASA Starship‑as‑station concept) giving updated schedules or program changes; these would ideally be checked directly, but the most recent information above already shows key trends.[1][4][10]

With those needs in mind, the evidence currently available points to Haven‑1 as effectively the only serious contender for a new, crew‑visited habitat before the end of 2027, with other stations clearly pushed into the late 2020s.

Resolution criteria recap

The question resolves “Yes” if, by December 31, 2027, humans visit any new orbital space habitat that is not the ISS or Tiangong. “New space habitat” here would mean a newly deployed, human‑tended structure in space that is designed for habitation or station‑like functions (e.g., Haven‑1 or a Starship repurposed as a station), not just a spacecraft making a short transit. A “visit” implies at least one crewed mission docking and astronauts entering and using the habitat, rather than a purely robotic or cargo mission.

Official resolution sources would logically include program pages for Orbital Reef, Starlab and any NASA statements about Starship as a station, but the most recent dated reporting in July 2026 already establishes that Starlab and similar concepts are on post‑2027 timelines.[1][4][10]

Candidate 1: Vast Haven‑1 (and Haven‑2)

Schedule and hardware status

Multiple July 2026 articles agree that Haven‑1 is now targeting a launch in the first quarter of 2027, after slipping from an earlier 2026 plan.[3][5][11] The station is described as a single‑module, 14,600‑kg habitat about 4.4 m in diameter and 10.1 m tall, with 45 m³ of habitable volume, launching on a Falcon 9 to a ~425 km orbit at 51.6° inclination.[5] Haven‑1 is designed to host up to four astronauts at a time for missions of up to two weeks, with SpaceX Crew Dragon vehicles providing transport and, during visits, power and life support.[3][5]

The technical integration plan outlined in mid‑2026 suggests meaningful progress but also non‑trivial remaining work.[5] Vast has laid out three phases: installing thermal control and life‑support systems first, followed by avionics and navigation systems, and then crew habitation outfitting plus micrometeoroid protection, culminating in environmental testing of the integrated flight vehicle.[5] The company characterizes itself as roughly 40% of the way toward its longer‑term goal of a continuously crewed station, indicating that a short‑duration, intermittently occupied demo phase is planned before permanent habitation.[5]

Crewed mission plans and commercial commitments

Analysts now rank Haven‑1 and Haven‑2 as leading U.S. commercial space station projects, and they highlight extensive planning for crewed use.[2] One July 2026 ranking notes Vast plans to operate Haven‑1 for a three‑year period during which the station will host at least four 2‑week-long crewed missions, one including a French astronaut, and mentions preliminary deals with Lithuania, Colombia, Uzbekistan, Japan, the Czech Republic, the Maldives and four biomedical companies for potential astronaut flights or payloads.[2] Vast is reported to have raised more than a billion dollars and to have already flown a small unmanned demo module, which supports the feasibility of launching and operating Haven‑1 in the near term.[2]

The Portuguese report similarly emphasizes that Haven‑1 is designed to accommodate up to four astronauts from both space agencies and private entities, with mission durations around two weeks.[3] This confirms that early operational scenarios explicitly involve human visitors, rather than purely robotic operations.[3] In addition, NASA’s own description of Haven‑1 (as quoted in the technical article) calls it a microgravity environment for crew, research and in‑space manufacturing, reinforcing the expectation of crewed visits.[5]

Latest schedule risk for first human visit

While the launch is now “no earlier than Q1 2027,” there is explicit caution that crewed occupancy may lag the launch by a significant margin.[11] A July 9, 2026 commercial space report states that although Haven‑1 has been delayed to 2027, “it could be significantly longer before the station gets its first crew,” pointing directly to uncertainty around when astronauts will actually visit.[11] This is a key new datapoint for the superforecaster: it implies that even if launch occurs in early 2027, the first crewed mission might slip into 2028 or later.

Compounding this, NASA in early 2026 awarded Vast a private astronaut mission to the ISS, targeted for no earlier than summer 2027, with four crew spending up to two weeks aboard the ISS and SpaceX providing transport.[5] That mission uses Vast and SpaceX resources but is focused on the ISS rather than Haven‑1, potentially competing for operational and integration attention in mid‑2027.[5] Together, these facts suggest that the earliest plausible sequence for Haven‑1 is: launch in Q1 2027, commissioning and check‑out through at least part of 2027, and a first crewed visit that may or may not occur before year‑end 2027 depending on how aggressively Vast and SpaceX can schedule human flights.

From a movement standpoint, the July 2026 updates are mixed. On the positive side, they confirm continued funding, technical progress and concrete crewed mission plans.[2][3][5] On the negative side, they formalize the slip to 2027 and publicly flag uncertainty on the timing of the first crewed visit, which is directly relevant to the resolution criterion.[11]

Candidate 2: Orbital Reef (Blue Origin / Sierra Space)

The available July 2026 sources summarized above focus mainly on Haven‑1, Starlab and Axiom, and do not provide fresh, dated schedule details for Orbital Reef.[1][2] Orbital Reef is mentioned in the context of “five American space stations presently under development,” but the excerpted ranking text concentrates on Vast’s Haven‑1/Haven‑2, implying that Orbital Reef is not seen as the leading near‑term contender for initial occupancy.[2]

Earlier public information (outside these July 2026 articles) has generally placed Orbital Reef’s initial operational timeframe in the late 2020s, and there are no recent sources here indicating an acceleration into the 2025–2027 window. In the absence of current reporting on firm launch or crew dates before 2028, Orbital Reef appears unlikely to produce a new, crew‑visited habitat by the end of 2027, and it should be treated as a lower‑priority candidate relative to Haven‑1 for this question.

Candidate 3: Starlab (Voyager Technologies / Airbus)

Timeline and role as ISS replacement

Multiple July 14, 2026 articles describe Starlab as a commercial station intended to replace the ISS after its planned end of mission around 2030.[4][10] Starlab is reported to have an internal area of about 450 m², providing substantial space for research and manufacturing, and is expected to launch in 2029 aboard SpaceX’s Starship.[4] These reports explicitly tie Starlab’s operational timeframe to the post‑2030 era, with initial launch years clearly beyond 2027, making it irrelevant for the question’s deadline.[4][10]

The equity research article on Voyager Space reinforces this schedule.[1] It states that Starlab is targeting a 2029 launch on Starship with a pressurized volume approximately 45% of the ISS’s U.S. segment, and it contrasts this later schedule with earlier efforts like Axiom’s station (2028) and Vast’s Haven‑1/Haven‑2 (from 2027).[1] This comparative framing underscores that, among competing commercial stations, Starlab is intentionally positioned as a follow‑on habitat for the 2030s rather than an early entrant.[1]

Commercial agreements and implications

The Korean coverage highlights that SpaceLintech, a Korean space‑medicine company, has secured future utilization space on Starlab for AI‑based space medicine research and manufacturing.[4][10] This indicates strong commercial interest and long‑term planning for Starlab’s use, but all such plans are framed around “2030 and beyond,” consistent with its role as an ISS replacement.[4][10] For the forecast horizon ending in 2027, Starlab’s updates are informative mainly as confirming that it will not contribute to an early “Yes” resolution.

There is no suggestion in these sources of a precursor Starlab demonstrator or module that could be visited by humans before 2027; all references point to a single, integrated station with a late‑decade launch.[1][4][10]

Candidate 4: NASA using SpaceX Starship as a space station

Starship development status and NASA’s focus

The July 13, 2026 report on Starship’s upcoming “flight 13” test emphasizes NASA’s need for Starship

Grok response:

Here is a curated list of 10 recent, relevant sources on commercial space station developments, focusing on Haven-1, Orbital Reef, Starlab, Axiom, and related NASA plans as of mid-2026. These emphasize timelines for launches and crewed visits through 2027–2028.[1][2]

1. Wikipedia: Haven-1 (ongoing entry, key updates referenced through early 2026): Details Vast’s Haven-1 as the planned first commercial space station, with uncrewed Falcon 9 launch NET Q1 2027 and first crewed Vast-1 mission (4 astronauts, ~30 days on Crew Dragon) also NET 2027. Assembly began January 2026 after delays from a prior mid/late-2026 target; it remains privately funded.[1]
2. Payload Space: “Vast Delays Haven-1 Launch to 2027” (January 20, 2026): Reports Haven-1 launch slipped to no earlier than Q1 2027; crewed operations will follow only after uncrewed commissioning and safety validation, potentially pushing the first human visit beyond immediate post-launch. CEO notes Dragon will provide initial life support/power.[2]
3. Ars Technica: “The first commercial space station, Haven-1, is now undergoing assembly for launch” (January 20, 2026): Confirms the Q1 2027 uncrewed launch shift; Vast is not launching with crew aboard initially, with crewed Dragon missions planned afterward in 2027 to demonstrate operations.[3]
4. NASA: “Commercial Space Stations” page (updated August 26, 2024, with ongoing references): Outlines CLD program timelines, including Phase 2 proposals in late 2025 and awards in early 2026 for Blue Origin’s Orbital Reef and Starlab; emphasizes transition from ISS (deorbit ~2030) but notes no immediate operational free-flying stations.[4]
5. Orbital Radar: “Commercial Space Stations 2026” (June 18, 2026): Ranks Orbital Reef as ~2028+ with strong research capability but lagging; Blue Origin/Sierra Space program delayed relative to competitors like Vast or Axiom.[5]
6. Space Scout: “Where are America’s Commercial Space Stations in 2025?” (June 10, 2025): Notes Orbital Reef PDR still incomplete by mid-2025 (slipped from 2023–2024 targets), with Blue Origin and Sierra Space focused on other priorities like New Glenn and Dream Chaser, placing it behind Starlab.[6]
7. Payload Space: “Axiom Space Adjusts Space Station Plans” (December 18, 2024): Details Axiom shifting first module (PPTM power/thermal) to ISS in early 2027 (instead of habitat), with Hab-1 launch ~2028 to enable an independent two-module station; changes at NASA request.[7]
8. Axiom Space / Wikipedia cross-reference on Axiom Station (recent updates): PPTM targeted NET early 2027 attached to ISS; full free-flying Axiom Station (with Hab-1) not expected until 2028+, with ongoing private crew missions to ISS itself.[8]
9. ISDC/NSS: “Private Space Stations and the Future of Low Earth Orbit” (recent overview): Summarizes Vast Haven-1 as Q1 2027 target (first standalone commercial station if successful), Axiom free-flying assembly ~2028, and Starlab ~2029; notes Haven-2 follow-on in 2028+.[9]
10. Aviation Week: “Vast Station Launch Slips To 2027” (January 20, 2026): Echoes the delay for Haven-1 demonstration station to Q1 2027, positioning it to demonstrate crewed ops ahead of NASA-backed competitions, with uncrewed commissioning preceding any human visits.[10]

Additional context from sources (no single authoritative resolution source beyond the listed project pages): Haven-1 remains the nearest-term prospect for a new independent habitat, with uncrewed launch possible in Q1 2027 and crewed visits (Vast-1/Vast-2) targeted for 2027, though any slips in integration, testing, or safety reviews could push crewed operations into 2028.[2][3] Orbital Reef and Starlab show continued delays into the late 2020s with no 2027 crewed milestones indicated.[5][6] Axiom’s early modules attach to the ISS (not qualifying as a fully new standalone habitat under the criteria), with independent capability targeted for 2028.[7] No concrete near-term plans emerged for a Starship-based NASA station or other habitats enabling human visits before end-2027. Recent 2026 updates center on Haven-1’s schedule slip and assembly progress without reported further delays as of mid-year.

Systematic Analysis

Candidate Assessment

Haven-1 (Vast Space) — Primary candidate, essentially the only serious contender:

• Uncrewed launch target: Q1 2027 (already slipped from 2026)
• First crewed mission (Vast-1, 4 astronauts, ~30 days): NET 2027
• Current status (July 2026): Assembly ongoing, ~40% toward long-term crewed ops goal
• Key complication: Uncrewed commissioning/checkout must precede crewed visit
• Explicit caution in July 2026 reporting: “it could be significantly longer before the station gets its first crew”
• Competing resource: Vast/SpaceX ISS private astronaut mission slated for Summer 2027

Orbital Reef, Starlab, Starship-as-station: All firmly post-2027 timelines based on current evidence. Starlab 2029+, Orbital Reef 2028+, Starship not planned as station.

Probabilistic Timeline for Haven-1 Crewed Visit

Launch Window	P(launch)	P(crew 2027	launch)	Contribution
Q1 2027	38%	45%	17.1%
Q2 2027	15%	22%	3.3%
Q3 2027	8%	8%	0.6%
Q4 2027	5%	3%	0.15%
No 2027 launch	34%	0%	0%

P(Haven-1 crewed visit 2027) ≈ 21%

P(Other candidate) ≈ 2%

Combined ≈ 22-23%

Key Assumptions at Risk

1. Haven-1 launches Q1 2027 as planned (P(wrong) ≈ 62%): Space hardware consistently slips; this station already slipped once from 2026. Manufacturing and integration issues are common.
2. Commissioning is rapid enough for 2027 crew visit (P(wrong) ≈ 55%): After uncrewed launch, safety validation + check-out + SpaceX scheduling + crew training could easily push first human visit into 2028. The reporting explicitly flags this risk.
3. No unexpected acceleration from competitors (P(wrong) ≈ 5%): Axiom’s module in 2027 attaches to ISS (excluded), not a new independent habitat.

Historical Base Rate Consideration

Commercial human spaceflight programs (Dragon, Starliner, Dream Chaser, commercial stations) have slipped by 12-24+ months consistently. The base rate for hitting an optimistic commercial space milestone on time is very low. The question requires both launch AND crewed visit within 18 months.

Calibration Check

Haven-1’s crewed visit requires a chain of events: (1) successful uncrewed launch, (2) successful commissioning, (3) Crew Dragon mission scheduling, (4) mission execution — all within the 2027 calendar year. Each step has failure/delay probability.

Probability: 22%
The extracted probability is: 22%

Reasoning and Analysis

Framework

This is an “Other Binary Outcome Event” with 18 months remaining (July 2026 to December 2027). I need to assess each candidate’s probability of contributing a “Yes” resolution.

Candidate Assessment

Haven-1 (Vast) — Primary candidate:

• Current status (July 2026): In assembly, targeting Q1 2027 uncrewed launch (already slipped from 2026)
• Mission profile: Uncrewed launch first → commissioning → crewed Vast-1 mission
• Key complication: Sources explicitly state “it could be significantly longer before the station gets its first crew” even after launch

Orbital Reef, Starlab, Starship-as-station: All targeting 2028+ or later, negligible contribution.

Axiom modules: First module attaches to ISS in 2027, likely wouldn’t qualify as “new space habitat” under resolution criteria.

Haven-1 Probability Breakdown

Launch scenario	P(scenario)	P(human visit by EOY 2027 | scenario)	Contribution
Q1 2027 launch	30%	55%	16.5%
Q2 2027 launch	25%	35%	8.75%
Q3 2027 launch	15%	15%	2.25%
Q4 2027 launch	10%	5%	0.5%
No 2027 launch	20%	~0%	0%

Total Haven-1 contribution: ~28%

Critical Assumptions & Failure Probabilities

1. Haven-1 launches by mid-2027: Already had one slip; continued supply chain and testing risks exist. Probability of assumption being WRONG (slips to 2028+): ~20%.
2. Commissioning completes fast enough for 2027 crew visit: Even with timely launch, commissioning of a new, novel habitat type with new safety protocols may take 6-9+ months. Probability of assumption being WRONG (too slow even if timely launch): ~30-35%.
3. No other candidate accelerates: Orbital Reef, Starlab all have fundamental multi-year gaps. Probability of assumption being WRONG: ~3%.

Additional Considerations

• Base rate: Only ~35% of forecasting questions resolve positively
• Space hardware consistently experiences schedule slippage (anchoring bias toward optimistic schedules)
• The explicit public warnings from industry sources about crewed-visit timing uncertainty add credibility to the risk
• Haven-1’s substantial funding ($1B+) and manufacturing progress are genuine positives
• The 18-month window provides meaningful time for Haven-1’s program but the sequential nature (launch → commissioning → crewed visit) means compounding delays

Calibration

My structural estimate lands at ~28-30%. This aligns reasonably with the base rate (35%), adjusted down for the sequential dependency chain and history of space hardware delays.

Probability: 28%
The extracted probability is: 28%

Analysis

Question Framework

This question resolves “Yes” if humans visit a new space habitat (not ISS/Tiangong) before December 31, 2027. Today is July 15, 2026, giving ~18 months remaining.

Candidate Assessment

Haven-1 (Vast) – Primary Candidate

• Launch target: Q1 2027 (slipped from 2026)
• Crewed missions: Planned for 2027 (Vast-1 with 4 crew, ~30 days)
• Current status: Assembly underway since January 2026, 3-phase integration plan in progress, $1B+ raised, unmanned demo previously flown
• Critical warning (July 9, 2026): “it could be significantly longer before the station receives its first crew”
• Crew Dragon provides initial life support while docked – astronauts would enter Haven-1 for work

Other Candidates

• Starlab: 2029 launch, explicitly post-2030 operations → irrelevant
• Orbital Reef: 2028+ timeline → irrelevant
• Axiom modules: Attach to ISS → wouldn’t qualify
• Starship as station: No concrete plans → irrelevant

Key Assumptions and Failure Probabilities

Assumption 1: Haven-1 launches in Q1 2027 as targeted (most impactful)

• Probability it slips further: ~60-65%
• Space hardware typically slips 6-18 months beyond targets
• Already slipped once from 2026

Assumption 2: Post-launch commissioning is short enough (~4-6 months) to allow 2027 crewed visit

• Probability this is optimistic: ~50%
• New stations require extensive checkout; even ISS-experienced operators face novel challenges

Assumption 3: No additional delay from technical/regulatory/funding issues

• Probability of unforeseen complications: ~25%

Probability Calculation

Launch Window	Probability	P(Crewed Visit in 2027)	Contribution
Q1 2027	0.32	0.50	0.160
Q2 2027	0.18	0.30	0.054
Q3 2027	0.10	0.12	0.012
Q4 2027	0.05	0.04	0.002
No 2027 launch	0.35	0.00	0.000

Haven-1 contribution: ~23%
Other candidates (wild card): ~2%

Adjustments

• Historical base rate of new space habitats receiving human visits: essentially zero in recent decades
• This is a genuinely novel commercial era with resources and demonstrated technology
• Space projects routinely slip relative to ambitious schedules
• Overconfidence correction (consistent pattern in forecasting competitions)

Final combined estimate: ~25%

Probability: 25%

This forecast assesses the probability of humans visiting a new space habitat, excluding the ISS and Tiangong, between July 15, 2026, and December 31, 2027. The analysis of potential candidates and their timelines indicates that the resolution of this question hinges almost entirely on the progress of a single project: Vast’s Haven-1.

Analysis of Potential Candidates

• Starlab (Voyager/Airbus): Recent reports from July 2026 consistently place Starlab’s launch target in 2029, with operations intended to begin around 2030 as a replacement for the ISS. Therefore, Starlab will not contribute to a “Yes” resolution.
• Orbital Reef (Blue Origin/Sierra Space): This project is generally understood to be on a later timeline. While mentioned as one of five US stations in development, analysis ranks it as lagging competitors, with an operational timeframe of 2028 at the earliest. It is not a contender for a

Analysis

Question Framework

This question resolves “Yes” if humans visit a new space habitat (not ISS/Tiangong) before December 31, 2027. Today is July 15, 2026, giving ~18 months remaining.

Candidate Assessment

Haven-1 (Vast) – Primary Candidate

• Launch target: Q1 2027 (slipped from 2026)
• Crewed missions: Planned for 2027 (Vast-1 with 4 crew, ~30 days)
• Current status: Assembly underway since January 2026, 3-phase integration plan in progress, $1B+ raised, unmanned demo previously flown
• Critical warning (July 9, 2026): “it could be significantly longer before the station receives its first crew”
• Crew Dragon provides initial life support while docked – astronauts would enter Haven-1 for work

Other Candidates

• Starlab: 2029 launch, explicitly post-2030 operations → irrelevant
• Orbital Reef: 2028+ timeline → irrelevant
• Axiom modules: Attach to ISS → wouldn’t qualify
• Starship as station: No concrete plans → irrelevant

Key Assumptions and Failure Probabilities

Assumption 1: Haven-1 launches in Q1 2027 as targeted (most impactful)

• Probability it slips further: ~60-65%
• Space hardware typically slips 6-18 months beyond targets
• Already slipped once from 2026

Assumption 2: Post-launch commissioning is short enough (~4-6 months) to allow 2027 crewed visit

• Probability this is optimistic: ~50%
• New stations require extensive checkout; even ISS-experienced operators face novel challenges

Assumption 3: No additional delay from technical/regulatory/funding issues

• Probability of unforeseen complications: ~25%

Probability Calculation

Launch Window	Probability	P(Crewed Visit in 2027)	Contribution
Q1 2027	0.32	0.50	0.160
Q2 2027	0.18	0.30	0.054
Q3 2027	0.10	0.12	0.012
Q4 2027	0.05	0.04	0.002
No 2027 launch	0.35	0.00	0.000

Haven-1 contribution: ~23%
Other candidates (wild card): ~2%

Adjustments

• Historical base rate of new space habitats receiving human visits: essentially zero in recent decades
• This is a genuinely novel commercial era with resources and demonstrated technology
• Space projects routinely slip relative to ambitious schedules
• Overconfidence correction (consistent pattern in forecasting competitions)

Final combined estimate: ~25%

Probability: 25%
