Sixty tests, checked against the news every Sunday

No peer-reviewed report of a mammal conceived, born and weaned at one-sixth to one-half gravity appeared. The nearest items are old JAXA centrifuge mouse work (2017 paper, 2019 lunar-gravity flight with no reproduction result) and a China microgravity mouse birth after return to Earth in December 2025.

No crewed spin-gravity mission has flown or been scheduled; Vast has only discussed spin tests of Haven-1 (one uncrewed at end of life) and Vast-1 is a stay of up to 30 days with a launch date of 2027 or later.

The verify claim is settled: CAS reported in December 2022 that rice completed a seed-to-seed cycle on Tiangong (2022-07-29 to 2022-11-25, about 120 days), with six seeds yielding 59. Shenzhou-23's rice harvest was reported in August 2026 and tomatoes in March 2026, but no source gives a harvest mass near one kilogram, so the criterion is not met.

AlphaEvolve question: its mathematics results are still an arXiv preprint (2511.02864, Georgiev, Gomez-Serrano, Tao, Wagner, 2025-11-03) and the search found no journal acceptance, so no peer-reviewed record yet says the construction was the system's. AlphaTensor facts are confirmed (Nature, October 2022, 47 multiplications for 4x4 over GF(2)) and, under the strict reading ruled 2026-10-06, it does not resolve the step. New candidate: an OpenAI internal model's disproof of Erdős's unit-distance conjecture (announced 2026-05-20 or 21, checked by external mathematicians including Alon and Gowers), with no journal publication found.

No spacecraft is generating a megawatt in orbit; Gateway was paused in March 2026, its 60 kW power element is being repurposed for SR-1 Freedom (about 20 kW reactor, launch targeted December 2028), and Russia's megawatt-class Zeus tug is not before about 2030.

No flight test of a megawatt-scale radiator exists or is scheduled; the nearest hardware is SR-1 Freedom's kilowatt-class radiators, with no published performance figures, and earlier deployable radiators rejected only hundreds of watts to about two kilowatts.

Starship has flown 14 times in total, with Flight 14 on 2026-09-28 the first to reach orbit; forecasters expect only a handful of flights in 2026, and Musk's weekly cadence target is for 2027, far from 100 qualifying flights in a year.

No ship has been caught or landed; Flight 14 (2026-09-28) ended in an ocean splashdown after about three hours and Flight 15, with the first planned tower catch of a ship, is provisionally no earlier than 2026-10-19 with no confirmed FAA approval found.

No ship-to-ship transfer has happened; the demonstration is listed as late 2026 or 2026 Q4 and is not confirmed scheduled, and the criterion needs 100 tonnes received.

Artemis III is now a 2027 Earth-orbit docking test and the first crewed landing is expected on Artemis IV in 2028; no new lander milestone surfaced in the window, and Blue Origin is repairing its pad after the May 2026 New Glenn explosion.

No ten-tonne, six-month storage has occurred; LOXSAT (a small liquid-oxygen demonstration on Rocket Lab Electron) has slipped repeatedly and its launch status could not be confirmed, and it is far below ten tonnes in any case.

No company reports ten million dollars of revenue from non-government customers for in-orbit computing or manufacturing; the orbital data-centre firms are private and show funding and valuations, not revenue, and Redwire's 2026 filings give no in-orbit manufacturing revenue split.

No orbit-to-ground power beaming has been reported; Aetherflux's kilowatt-class Mission 1 is still listed as a 2026 launch with no report of it flying, and Caltech's 2023 MAPLE test was far below a kilowatt received.

No insurer has announced cover with a premium of a million dollars or more on a private lunar asset; underwriters quoted in April 2026 said they want multiple successful missions first, and the only lunar precedent found is ispace's 2022 launch-to-landing policy.

No TRIAD lifespan analysis has been published; the trial is still enrolling toward 580 dogs under an NIH grant running to November 2029. Loyal's separate dog drug LOY-002 is not rapamycin and has two of three technical sections accepted by the FDA, with no approval.

No final guidance, pathway decision or approval naming aging as an indication appeared; the FDA chief scientist said at the ARDD meeting that its Focus Areas of Regulatory Science report, due early in fiscal year 2027, will list aging, which is a research-priority document, not guidance.

No qualification, guidance or agreed pivotal design using an aging clock as primary endpoint appeared; as of August 2026 epigenetic clocks are not among the eight qualified FDA biomarkers.

No peer-reviewed report of a mammal conceived, born and weaned in partial gravity appeared. Results only describe the existing JAXA MARS centrifuge work and planned reproduction studies.

No person has completed twelve months at partial gravity and no such health report appeared. Lunar surface stays remain planned at days to weeks, with Artemis crewed landing not before 2028.

No child has been born off Earth. A SpaceBorn United reproduction consortium met 2026-09-26 to 2026-09-28 in Amsterdam, which is a roadmap meeting, not the event.

No crewed spinning spacecraft has produced artificial gravity for thirty days. Vast says its rotating habitat is not before the 2030s, unchanged from the prior scan.

No rotating habitat with Earth-normal gravity exists or is under construction in orbit; results are only concepts such as Voyager Station and Von Braun, with repeated delays.

Neither route node has resolved; no milestone for either appeared in the window.

No peer-reviewed flight measurement of a shield halving deep-space dose appeared. Artemis I and II radiation work, including the AstroRad vest, is about solar events and orientation, not a matched 50 percent GCR comparison.

No off-Earth crew has done twelve months with over half of calories grown on site. Ground analogues like Lunar Palace and Tiangong recycling claims (about 95 percent water, 100 percent oxygen regeneration) do not meet the criterion.

No regulator approval or agency standard adoption of a treatment halving chronic space radiation risk appeared. Only research and countermeasure development was found.

The Tiangong two-generation rice harvest was on 2026-08-05, before the leaf window, and was a science sample collection with no reported one-kilogram edible harvest. A second wheat generation is nearing the end of its cycle but no harvest weight was reported.

No operation under anaesthesia has been performed off Earth. Only simulated robotic surgery on the ISS (SpaceMIRA) and parabolic flight anaesthesia studies appeared.

Anthropic reported Claude produced a full Lean formalization of Fermat's Last Theorem, checked by Kevin Buzzard, but it formalizes a known human proof so it is not a result beyond human work; OpenAI's Navier-Stokes claim (2026-09-08) still has no independent peer review and Clay has not accepted it, and Axiom Math has AI proofs accepted by journals, though not shown acknowledged as beyond human results. Probability is already 0.95 so nothing moves.

No new evidence of an AI-originated concept reaching the two-textbook or majority-of-papers bar in a named field; results were general AlphaFold and AlphaEvolve background.

No confirmed technosignature or complex-life detection; K2-18b microbial biosignature claims are increasingly disputed and Mars findings concern possible microbial proxies, neither meeting the criterion.

No verified non-human signal exists to decode; the only decoding story is the 2023 SETI Institute Sign in Space art project simulation.

No independently replicated inside measurement for any AI system and no resolved C2 precursor; only symposium papers and an upcoming book on machine consciousness appeared.

No reactor-powered spacecraft has flown or accumulated delta-v in the window; DARPA DRACO was cancelled in 2025 and SR-1 Freedom remains a plan for a December 2028 launch.

No new nuclear-propulsion mission flew or was funded in the window; DRACO stays cancelled and SR-1 Freedom is still a 2028 plan.

Starship Flight 14 reached orbit on 2026-09-28 and was cut short, but no mission reached the asteroid belt within twelve months of leaving Earth; Psyche arrives in 2029 after a multi-year cruise.

No megawatt-class solar-electric mission flew in the window; the PPE is about 60 kilowatts and NASA's lithium MPD thruster work (120 kilowatts, February 2026) is ground testing.

Nothing new in the window; Artemis II flew around the Moon in April 2026, well short of five million kilometres, and crewed Mars plans remain undated, with uncrewed Starships targeting the November to December 2026 window.

No in-space test reached 100 km/s exhaust speed with over one kilonewton; Pulsar Fusion's Sunbird first plasma (April 2026) is a ground test, and thrust measurement is only a stated next step.

No site beyond the Earth-Moon system is crewed; a 2026-07-25 multi-agency roadmap only plans a lunar base and crewed Mars around 2035.

No operator reported a spacecraft generating and using a megawatt in orbit since 2026-09-27. Results show only plans (Orbital Composites 2027 kilowatt demo, K2 Space buses of about 20 kilowatts).

Idaho National Laboratory's request for information on Fission Surface Power closed 2026-09-08, with a request for proposals to follow, and the target remains about 2030. Plans and procurement steps only, no reactor operating.

No lunar site with 100 kilowatts through the night was reported. Northrop Grumman's Lunar Infrastructure Demo plans (announced 2026-08-04, before the window) and Astrobotic LunaGrid (operational 2028 target) are plans.

No polar solar-plus-storage system has operated on the Moon; Astrobotic's LunaGrid and VOLT remain in ground testing with an operational target of 2028.

No orbit-to-Moon power delivery was reported; Volta's LightGrid is a plan with an Earth-orbit test and surface benefit not before 2028.

No price list or procurement record at 15 dollars per kiloamp-metre or less appeared; results only restate industry targets of 10 to 20 dollars per kiloamp-metre.

No fusion plant exported net electricity. Helion's Orion is under construction with a grid connection required by end of 2028 and SPARC is not designed to produce electricity.

No 100 megawatt system at or under 100 tonnes was tested. Only an unsubstantiated Kepler Fusion 2026 target appeared, with no mass or test record.

No 100 megawatt space fission test was reported; the nearest flight plan is SR-1 Freedom at about 20 kilowatts electric, scheduled for end of 2028.

No megawatt, thirty-day vacuum heat rejection flight test was reported. A shape-memory-alloy radiator flight test is scheduled for spring 2027 at far smaller scale, and MARVL is design work.

Starship Flight 14 launched 2026-09-28 and reached orbit (about 275 km) for the first time, deploying 26 Starlink V3 satellites, but one Raptor shut down early and the ship was deorbited after about 2 orbits, splashing down in the Pacific roughly 3 hours after liftoff. This is the first Starship orbital flight, one of the 100 needed in a calendar year, and neither stage is a reuse flight, so no probability moves; the criterion needs 100 orbital flights by a fully reusable vehicle with both stages recovered on half of them.

On Flight 14 (2026-09-28) the booster splashed down in the Gulf of Mexico and the ship made a controlled splashdown in the Pacific, with no tower catch attempted for either stage; neither was retrieved or declared reflight-ready. The flight reached orbit but no recovery occurred, so the criterion is not met and no probability moves; catch attempts are deferred to Flight 15, with provisional planning pointing to 2026-10-19 at the earliest.

No propellant transfer has been attempted as of 2026-09-26 per NASA OIG reporting; the demonstration remains targeted no earlier than late 2026 with no firm date, and the first Starship orbital flight on 2026-09-28 did not include one.

Plans are unchanged: Artemis III is a late-2027 Earth-orbit docking test with no landing, and the first crewed landing is Artemis IV, targeted for early 2028. No new schedule change surfaced in the window.

The only public Starship contract price found is the 90 million dollar figure from a Voyager Technologies filing, about 600 dollars per kg at 150 tonnes; Musk's 2026-07-29 sub-100-dollar claim is a target, not a sold price, and both predate the window.

No assembly of a structure over 100 metres from five or more launches was reported; results were concept studies and commercial station schedules (Haven-1 and Axiom modules slipping to 2027 or later).

No lunar material has been delivered to orbit in any quantity; activity is ground prototypes (NASA solar carbothermal demo in May 2026, Interlune's excavator prototype) and contracts for later this decade.

Neither route node has resolved; no lunar or asteroid material delivered to orbit was reported in the window.

No asteroid material delivery was reported; AstroForge's Odin lost contact after its February 2025 launch, its Vestri lander is still ahead, and Karman+ aims for a first launch in 2027.

No ten-tonne cryogenic storage in orbit was reported; the nearest effort, NASA and Eta Space's LOXSAT, is a roughly 135 kg satellite technology demonstration with a nine-month plan, far below ten tonnes, and a full-scale depot is not expected before 2030.

No propellant has been produced off Earth and fired; ISRU demonstrations remain ground work or planned flights, such as OffWorld's Prospector 1 scheduled for late 2027.

No filing showing ten million dollars of in-orbit service revenue appeared. Starcloud raised 250 million dollars on 2026-08-21 (before the window), is pre-commercial, and plans Starcloud-2 in October 2026.

No orbital power-beaming demonstration was reported as launched or completed in the window. OHISAMA and Aetherflux remain planned for 2026 with no new launch news.

Crew counts off Earth remain around 10 to 14 with a record of 19 (2024-09-11). Nothing near one hundred paid workers appeared.

No company reported profitable sales of an off-Earth product. Interlune's helium-3 supply agreements are future deliveries (2029 onward) and AstroForge is pre-revenue.

No new lunar-asset insurance policy with a million-dollar premium was reported. Results are general market commentary and older 2022 ispace coverage.

No change of head of government occurred; Congress passed a continuing resolution through 2026-12-11 keeping Artemis funded, which is not a backer change.

No NBER recession dating or end date appeared; the US is not officially in recession, with forecasters citing risk around 30 percent.

No legally binding ASAT test ban with US, China and Russia as parties appeared; the existing moratorium efforts are non-binding and Russia and China opposed them.

No treaty or mutually recognising laws on extracted-resource ownership appeared; China has no space-resources statute and still criticises the Artemis Accords.

No off-Earth site has published a permanent resident status; results were only academic discussion and ISS crew news.

No US-China instrument recognising each other's keep-out zones appeared; September 2026 commentary (NASA chief Isaacman) concerned racing to the lunar surface, not an agreement.

No multi-power body with enforcement authority over manoeuvres or launch windows exists; coordination remains informal and bilateral, with US civil traffic work moving to Commerce.

No primary lifespan analysis of TRIAD or an equivalent trial has been published; the trial remains in progress with about 170 dogs enrolled and a 580-dog goal, and the latest peer-reviewed TRIAD paper found is the 2025 design paper.

No final guidance, pathway decision or approval naming aging as an indication appeared; the Reagan-Udall Foundation meeting on gerotherapeutic regulatory constructs was held 2026-05-27 and its summary is dated 2026-07-31, both before the window, and is discussion only.

No qualifying trial reported results; TAME is still not fully funded or reported, with no efficacy results as of 2026.

No FDA or EMA approval with an aging or healthspan indication appeared; the only aging-labelled item is a veterinary (dog) drug that cleared an FDA step in April 2026, which does not meet the human-regulator criterion as read here.

No placebo-controlled trial in unselected older adults reporting a 25 percent or greater all-cause mortality cut appeared; search returned only older observational and nursing-intervention studies.

The oldest validated living person is Ethel Caterham of the UK, born 1909-08-21, about 117 years old, well short of the 122 years 164 days needed; Jeanne Calment's record is unchanged.

No FDA or EMA qualification, guidance or agreed pivotal design using an aging clock as primary endpoint appeared; as of August 2026 epigenetic clocks are not among the eight biomarkers qualified, and the 2026-09-07 Insilico framework paper is a proposal, already noted last scan.

The TRIAD trial remains in its treatment and observation phases, with early enrollees such as Zoe and Jack having completed the three-year study period but no primary lifespan analysis published in the window; nothing changed since the 2026-09-20 scan.

No FDA or EMA guidance, pathway decision, or approval establishing aging or a composite of age-related diseases as an approvable indication appeared in the window; the FDA's Plausible Mechanism Pathway, launched earlier in 2026 for individualized therapies, predates the window and does not itself name aging as an indication.

No new FDA or EMA qualification of a biological aging clock as a primary trial endpoint appeared in the window; the Nature Biotechnology paper on six proteomic aging clocks in the rentosertib trial, published 2026-09-07, predates the window and explicitly treats the clocks as exploratory, not FDA-qualified.

The FAA granted final launch approval on 2026-09-26 and SpaceX completed the pre-launch rehearsal, setting Starship's first orbital flight attempt (Flight 14) for 2026-09-28, after slipping from 2026-09-22. The vehicle has still not reached orbit even once, so the hundred-flights-in-a-year criterion is unaffected; this is a schedule update, not an event the criterion counts.

Flight 14's plan is unchanged from the 2026-09-20 scan: both the booster and the ship will attempt controlled splashdowns rather than tower catches, with the first ship-catch attempt still pushed to the undated Flight 15.

The dedicated ship-to-ship propellant transfer demonstration remains targeted for no earlier than late 2026 with no firm date; nothing new appeared in the window.

Artemis III remains redefined as a 2027 test of the two landers and Orion in Earth orbit with no crewed landing, with the first crewed lunar landing still assigned to Artemis IV, targeted for early 2028; unchanged since the 2026-09-20 scan.

No operator reported ten tonnes of cryogenic propellant held in orbit for six months and then burned; boil-off mitigation work (mechanical cryocoolers, multi-layer insulation) remains at the design and short-duration-test stage, unchanged since the 2026-09-20 scan.

No operator reported a spacecraft generating and using a megawatt of power in orbit in the window; NASA's lithium-fed magnetoplasmadynamic thruster testing, aimed at 500 kilowatts to 1 megawatt per thruster in coming years, remains ground-based development.

Sierra Space completed thermal-vacuum-chamber testing of a deployable radiator prototype at NASA Johnson in the window, but this is a ground-based, short-duration test, not a megawatt-scale, thirty-day vacuum heat-rejection flight test; nothing meets the criterion.

The NASA-JAXA Joint Partial-gravity Rodent Research centrifuge study, the closest ongoing effort, exposes adult mice to thirty days of partial gravity rather than a full gestation-to-weaning cycle; SpaceBorn's proposed embryo-in-orbit missions remain planned for later this decade. No published result meets the criterion.

Haven-1 itself does not spin; Vast's spinning artificial-gravity ambition sits with Haven-2 and beyond, with no firm date, and its crewed artificial-gravity demonstration (Vast-2) remains at no earlier than 2027. Unchanged since the 2026-09-20 scan.

No harvest of a staple crop off Earth was reported in the window; lunar-potato research remains ground-based work at Oregon State, and the ISS Veggie system grows salad greens, not a calorie crop to harvest weight.

Varda announced new Chief Revenue Officer and Chief Financial Officer hires in the window but disclosed no revenue figure; its largest customer relationship, the United Therapeutics partnership, was signed in May 2026, before the window, and no ten-million-dollar annual revenue figure has been disclosed.

OHISAMA has still not launched in the window; it remains slated for fiscal year 2026 on Space One's KAIROS rocket, and mission specifications show its total output is about 720 watts, below the kilowatt threshold even if the demonstration succeeds.

No insurer or insured reported a lunar-asset policy in the window; coverage discussion remains general to the space insurance market (estimated at 4.43 billion dollars in 2026), with no named lunar-surface or lunar-orbit policy.

OpenAI's disputed Navier-Stokes construction, announced 2026-09-08, remains under review: as of 2026-09-26 the Clay Mathematics Institute still lists the problem as active and OpenAI has not claimed the prize, while the priority dispute with Buckmaster and Alpoge continues unsettled. Unchanged since the 2026-09-20 scan.

No report of a full gestation-to-weaning cycle at partial gravity appeared in the window; the NASA-JAXA Joint Partial-gravity Rodent Research centrifuge study on the space station remains the closest ongoing effort but has not published results.

No crewed spin-gravity flight occurred in the window; Vast's crewed artificial-gravity demonstration (Vast-2) remains planned for no earlier than 2027, unchanged since the 2026-09-19 scan.

The only harvest news found, University of Texas chickpeas grown in simulated lunar regolith, is ground-based work from March 2026 that predates the window and does not meet the off-Earth-site requirement; nothing grown off Earth was reported.

OpenAI's disputed Navier-Stokes manuscript, announced 2026-09-08, remains unresolved in the window: the Clay Mathematics Institute still lists the problem as unsolved and has not certified the claimed counterexample, and the priority dispute with mathematicians Tristan Buckmaster and Levent Alpoge continues unsettled. Nothing changed since the 2026-09-19 scan first noted this.

No operator reported a spacecraft generating and using a megawatt of power in orbit in the window; the nearest project, NASA's Space Reactor-1 Freedom at just over 20 kilowatts, remains years from that scale and targets a December 2028 launch.

Nothing in the window reports a megawatt-scale radiator tested in vacuum for thirty days; NASA's modular assembled radiator work (MARVL) remains a design study addressing deployable area, not a flight test.

No orbital Starship flight has occurred; Flight 14, its first attempted orbital flight, remains targeted for 2026-09-28 after slipping from 2026-09-22. This is the same delay already reported in the 2026-09-19 scan; nothing new in the window.

Confirmed again in the window: Flight 14 on 2026-09-28 will not attempt a tower catch of either stage, splashing both down in the Gulf of Mexico instead, with the first ship-catch attempt pushed to the undated Flight 15. This matches the 2026-09-19 scan's finding; nothing changed.

The dedicated Starship-to-Starship propellant transfer demonstration remains scheduled for the fourth quarter of 2026 with no firm date; nothing new appeared in the window.

No new lunar-landing news appeared in the window; Artemis III remains a redefined 2027 test mission, with the first crewed landing still planned for Artemis IV around 2028.

No operator reported ten tonnes of cryogenic propellant held in orbit for six months and then burned; boil-off mitigation research and depot concepts remain at the design and short-duration-test stage.

No new disclosure of 10 million dollars or more in a single year of orbital-work revenue appeared in the window; Varda's United Therapeutics partnership, its largest customer relationship, was signed in May 2026, before the window, and no revenue figure has been disclosed.

No kilowatt-scale orbit-to-ground power beam occurred in the window. One low-quality aggregator site claimed JAXA's OHISAMA had already demonstrated a transmission, but mid-September 2026 reporting confirms OHISAMA has not launched: it is slated to fly on Space One's KAIROS 5 rocket, whose first three flights all failed, most recently in March 2026. The uncorroborated claim is disregarded.

No insurer or insured reported a lunar-asset policy in the window; industry coverage describes lunar programmes as a segment of the space insurance market where commercial cover still cannot be structured.

The TRIAD trial remains in progress, with over 180 of a target 580 dogs enrolled and the first few having completed the three-year study period; no primary lifespan analysis has published, and the trial is slated to conclude in November 2029.

No FDA or EMA guidance, pathway decision, or approval accepting aging or a composite of age-related diseases as an indication appeared in the window; only unrelated age-related-disease approvals, such as a wet macular degeneration drug in July 2026, were found.

No FDA or EMA guidance or qualification accepting a biological aging clock as a primary trial endpoint appeared in the window. A 2026-09-07 Nature Biotechnology paper on six proteomic aging clocks in a rentosertib trial, which predates the window, treats them as exploratory measures and explicitly states none holds FDA Context-of-Use qualification.

The TRIAD trial is still enrolling and in its medication phase; no primary lifespan analysis has been published, so nothing bears on the criterion.

No FDA or EMA guidance accepting slowing aging, healthy lifespan, or a composite of age-related diseases as an approvable indication was published in the window; the FDA still does not recognize aging as an indication.

AFAR, the TAME trial's own sponsor, is still fundraising to launch the trial as of 2026-08-29 and has not completed enrollment or published results. Several low-quality websites circulated an unverified claim of a positive interim result and an unrelated Eli Lilly endpoint claim; neither is corroborated by AFAR, ClinicalTrials.gov, or a primary source, so it is disregarded.

Loyal's LOY-002 has FDA acceptance of its effectiveness and safety technical sections from before this window, but full approval has not occurred; no FDA or EMA approval for a slowing-aging indication happened in the window.

No randomized trial in adults 65 and over with five or more years of follow-up reporting a 25 percent or greater cut in all-cause mortality was found; current rapamycin and senolytic trials measure healthspan biomarkers over shorter periods, not mortality.

Ethel Caterham, the GRG-validated oldest living person, turned 117 on 2026-08-21, well short of the 122-year, 164-day record; this does not change the probability.

No orbital Starship flight has occurred yet; Flight 14, planned as Starship's first orbital flight, slipped within the window from 2026-09-22 to 2026-09-28. Falcon 9 is on pace for over 110 launches in 2026 but its second stage is expended, so it does not count. The near-zero current cadence of a fully reusable heavy launcher is unchanged.

Flight 13 on 2026-07-24 lost the booster on an ocean-splashdown attempt and landed the ship in the ocean rather than catching it. Reporting from 2026-09-15 to 2026-09-18 confirms the now-delayed Flight 14 (2026-09-28) will attempt ocean splashdowns for both stages, not tower catches; the first ship-catch attempt has slipped to the undated Flight 15.

The dedicated Starship-to-Starship propellant transfer demonstration remains scheduled no earlier than the fourth quarter of 2026 with no firm date; nothing new appeared in the past week.

No new lunar-landing news appeared in the past week; Artemis III remains redefined as a 2027 test mission with the first crewed landing pushed to Artemis IV around 2028, per reporting that predates this window.

No published price list or signed public contract at 200 dollars per kilogram or less appeared in the five-week window; market trackers still put actual launch costs around 2,700 to 3,000 dollars per kilogram for most providers.

Nothing in the five-week window shows a structure over 100 metres assembled in orbit from five or more separate launches; precursor projects (a 1.4 metre DARPA truss demo, a planned 40 metre Orbital Assembly proof of concept) remain far smaller or unflown.

No evidence of lunar-origin material delivered to orbit at scale in the five-week window; lunar resource extraction remains at small-contract, technology-development stage.

No operator or independent report of a single spacecraft generating and consuming a megawatt continuously in orbit; megawatt-class solar and nuclear-electric concepts remain in the 2028 to 2032 planning stage.

NASA's SPARC or Lunar Reactor-1 solicitation for a 20 kilowatt lunar flight system remains a draft as of 2026-09-01, with no contractor selected; the January 2026 NASA-DOE agreement targeting a reactor by 2030 remains the operative plan. This is procurement-process news, not hardware progress toward operation.

No published price list or procurement record shows a tenfold drop in high-temperature superconducting tape price in the window; volume prices remain around 150 to 300 dollars per kiloamp-metre against a 50 dollar target.

On 2026-09-08 Helion's public affairs director publicly walked back the company's 2028 target for full operation of its 50 megawatt Microsoft power purchase agreement. Commonwealth Fusion's grid-interconnection application, filed before this window, remains in an early multi-year review. No fusion plant has exported net electricity to any grid.

DRACO remains cancelled after its FY2026 budget was zeroed in 2025, with no formal successor. NASA ran a ground cold-flow test campaign from July to September 2026 on a nuclear-electric propulsion engineering unit, and the Space Reactor-1 Freedom demonstrator still targets a 2028 launch. No in-space orbit change has occurred.

No nuclear-propelled mission beyond low Earth orbit has flown yet; the earliest demonstrators still target 2028 or later, so nothing bears on a three-missions-a-year cadence.

No new developments appeared in the window; SpaceX's announcement pushing a crewed Mars mission to roughly 2031 to 2033 dates to February 2026, before this window, and NASA and SpaceX focus remains on lunar Artemis missions.

Pulsar Fusion's Sunbird first-plasma milestone, a ground test with thrust and exhaust-speed measurement still pending, occurred on 2026-03-25, before this window; nothing new appeared in the current window.

No site beyond the Earth-Moon system is crewed at all; the lunar Gateway, itself only cislunar, still plans stays of 30 to 60 days rather than continuous year-long occupation.

No peer-reviewed report of a full gestation-to-weaning cycle in partial gravity appeared in the window; a March 2026 mouse-muscle study and a China Tiangong mouse-embryo experiment both predate the window and neither covers birth or weaning.

China's Shenzhou-23 crew, launched 2026-05-24, includes a planned year-long stay, and NASA published cardiovascular and joint health findings in August and September 2026, but all of this is in microgravity aboard Tiangong or the space station, not the partial gravity the criterion requires.

No pregnancy or birth off Earth was reported in the window; only speculative commentary pieces exist, confirming no such birth has occurred as of September 2026.

No crewed spin-gravity flight occurred in the window. Blue Origin's uncrewed NS-29 capsule spun cargo only for about two minutes of lunar gravity, before this window, and Vast's crewed artificial-gravity demonstration remains a plan targeted for the first quarter of 2027.

No rotating Earth-gravity habitat exists or is occupied; Orbital Assembly's Voyager Station remains an unbuilt design study, with nothing new in the window.

This node resolves only if B-human-year-in-partial-gravity-without-disqualifying-harm or B-earth-gravity-habitat-occupied-for-a-year resolves; both were checked above and remain open, so nothing to search independently.

The relevant publications found, a February 2026 shielding-experiment design paper and a modeling study claiming a 50 percent dose reduction, both predate the window and are design or ground studies, not a beyond-low-Earth-orbit flight measurement.

No off-Earth crew reported a twelve-month period meeting the calorie and recycling thresholds in the window; China's Yuegong-1 closed-loop results are ground-based simulations from 2017 and 2018, not off Earth.

No regulator approval or agency crew-health-standard adoption of a chronic-radiation-resistance treatment was found; radioprotectors for chronic low-dose cosmic-ray exposure remain in early research.

No new disclosure of 10 million dollars or more in a single year of orbital computing, manufacturing, or processing revenue appeared in the past week; the one in-window item, a 1.9 million dollar Space Force research award to Orbital Composites, is a development grant for ground-based work, not orbital customer revenue.

No kilowatt-scale orbit-to-ground power beam was confirmed in the past week; Japan's OHISAMA demonstration and Aetherflux's laser demo both remain pre-launch.

As of 2026-09-18, only 10 people are in space, all government astronauts split between the space station and Tiangong, far below the 100-person threshold. Vast's Haven-1 commercial station, the nearest-term new paid-crew site, has slipped from 2026 to the first quarter of 2027.

Industry coverage continues to describe off-Earth extraction as pre-revenue through at least 2028; no company reported profitable off-Earth-sourced product sales in the window.

Artemis hardware progress continued in the window (the Artemis IV SLS boattail arrived at Kennedy Space Center on 2026-08-31, and Artemis III stacking and an Orion trajectory fix were reported in September), and the proposed FY2027 budget raises Artemis funding from about 7.8 to 8.5 billion dollars, with a 2025 reconciliation bill already locking in roughly 4.1 billion dollars a year for SLS and Orion through fiscal year 2029. China's Long March 10 and Mengzhou hardware also continues testing toward a 2029-2030 crewed landing with no funding disruption reported. None of this yet tests a transition across a change of government, so it does not move the number.

The National Bureau of Economic Research has not declared a recession in 2026; the US remains in the expansion dated from April 2020, so there is no recession to test the node against.

No new debris-creating anti-satellite test by the United States, China, or Russia was reported in the window, and no treaty progress surfaced. A 2026-09-16 piece on India's growing anti-satellite capability is tangential, since India is not one of the three powers the criterion names.

A 2026-09-19 legal analysis and other 2026 commentary confirm the United States (the Artemis Accords, 67 signatories) and China (the International Lunar Research Station coalition with Russia) remain on separate legal tracks for off-Earth resource rights, with commentators calling for a treaty that does not yet exist. This confirms continued divergence rather than any movement toward alignment.

No off-Earth site has any resident yet; the coverage found, NASA's 2030s moon base plan, SpaceX's stated ten-year lunar-city ambition, and Mars sustained-presence projections for the 2030s, is forward-looking intent, not an actual residency event.

OpenAI published a manuscript on 2026-08-01 with ten pure-math and theoretical-computer-science results, each carrying a Lean 4 machine-checkable certificate not fully checkable by a human reader, and on 2026-09-08 announced a large-scale agent run producing a Lean-verified result bearing on the Navier-Stokes Millennium Problem. The Navier-Stokes claim is disputed on priority grounds by other researchers and neither result has yet been acknowledged in the peer-reviewed record as beyond human capability, so the criterion is not yet met, though the direction is consistent with the already-high estimate.

No event in the window shows a specific AI-originated concept, one humans had not reached, crossing into textbook or majority-of-papers status; AlphaFold's roughly 40 percent share of new protein structures and broad tool adoption are pre-existing gradual trends, not a new event, and AlphaFold is a tool humans could in principle have built rather than a concept AI originated beyond human reach.

No new technosignature or biosignature claim appeared in the window; a K2-18b technosignature null result and null radio searches of interstellar object 3I/ATLAS both predate the window, and a 2026-09-18 commentary piece speculated about false alarms without reporting a new finding.

No claim of received and understood knowledge of non-human, non-human-built origin appeared in the window; only administrative news, an overhaul of the International Academy of Astronautics' post-detection protocol between June and August 2026, and continued absence of evidence per NASA and the All-domain Anomaly Resolution Office.
