## Question
Will South Korea announce a specific date for the 5th Nuri rocket launch before September 1, 2026?
## Description / Resolution Criteria
## Description
Korea JoongAng Daily (August 2, 2026): [Fifth Nuri rocket launch delayed to October over satellite thruster tests](https://www.koreajoongangdaily.com/korea/fifth-nuri-rocket-launch-delayed-to-october-over-satellite-thruster-tests/12803873)
> The fifth launch of Korea's homegrown Nuri rocket has been postponed until October due to problems with thrusters on nanosatellites to be carried aboard the vehicle, officials said Sunday.
> According to the Korea AeroSpace Administration (KASA) and the KAIST Satellite Technology Research Center, the launch was delayed from its original schedule to allow time to replace and test underperforming thrusters on some nanosatellite payloads.
> Thrusters provide the propulsion needed for satellites to adjust or maintain their orbits and are key components for nanosatellites that fly in formation while maintaining fixed intervals.
> The final launch date will be determined at a launch management committee meeting scheduled for late August, he added.

## Resolution Criteria
This question resolves as **Yes** if, according to [credible sources](https://www.metaculus.com/faq/#definitions), before September 1, 2026 a body with the authority to do so, such as the launch management committee of the [Korea AeroSpace Administration](https://www.kasa.go.kr/), announces a single specific date for the fifth [launch](https://en.wikipedia.org/wiki/Nuri_\(rocket\)#Launches) of the Nuri rocket. 
## Fine Print
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/45088) which opened on 2026-08-07 09:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.
## Sub-question decomposition
- (w=0.40) Will the Korea AeroSpace Administration launch management committee (발사관리위원회) actually convene as scheduled in late August 2026 (i.e., before September 1, 2026)? — The announced pathway to a specific date is the late-August committee meeting; if it slips to September, the question al
- (w=0.35) Conditional on the committee meeting, will it announce a single specific calendar date (not a window/month) for the 5th Nuri launch, publicly reported before September 1, 2026? — Past KASA committee meetings have historically set a specific target date plus backup window; but sometimes they announc
- (w=0.15) Will the nanosatellite thruster replacement/testing issue (or any new technical/weather/administrative issue) be resolved sufficiently by late August 2026 to permit date-setting? — The stated cause of delay must be cleared before a firm date can be fixed; unresolved payload issues would push the deci
- (w=0.10) Will a specific date be publicly announced via any other authoritative route (e.g., KASA press release, ministry briefing, official launch notice/NOTAM-equivalent) before September 1, 2026, independent of the committee meeting timing? — Captures alternate resolution pathways such as pre-meeting announcements or official statements naming an exact date.

- No confirmation of the exact late-August 2026 committee meeting date
- No Korean-language news after ~Aug 15, 2026 covering committee outcome
- No data on whether thruster verification testing completed on schedule
Key uncertainties:
- Whether committee announces a single date or only 'October' / a window
- Possible further slippage pushing the meeting into September
- Whether announcement is publicly reported before Sept 1 vs. internal only
- Chuseok scheduling effects on committee timing
## Required pre-forecast walkthrough
Before giving probabilities, walk through these explicitly:
(a) The time left until the question resolves.
(b) The status quo outcome — what happens if nothing changes from today.
(c) A brief scenario that results in NO.
(d) A brief scenario that results in YES.
## Calibration guidance
- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.

Avoid \u003e0.97 or \u003c0.03 unless the outcome is already settled or near-tautological \u2014 overconfident misses are punished heavily by the log score.\n- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question \u2014 move further only with specific evidence the market lacks.\n- **Treat research as fallible, not ground truth.** A single-source or \"very recent\" claim \u2014 especially one the evidence flags as unverified, possibly AI-generated, or low-credibility \u2014 must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.\n- **Also provide a holistic estimate** \u2014 your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.\n\n## Output\n\nReturn ONLY valid JSON, no markdown fences:\n\n{\n \"rationale\": \"\u003caddress (a) (b) (c) (d) above \u2014 5-8 sentences total\u003e\",\n \"sub_question_estimates\": {\n \"sq1\": \u003cfloat in [0.01, 0.99]\u003e,\n \"sq2\": \u003cfloat in [0.01, 0.99]\u003e,\n \"sq3\": \u003cfloat in [0.01, 0.99]\u003e,\n \"sq4\": \u003cfloat in [0.01, 0.99]\u003e\n },\n \"holistic_p_yes\": \u003cfloat in [0.01, 0.99] \u2014 your overall estimate ignoring the decomposition\u003e,\n \"what_would_change_my_mind\": \"\u003c1-2 sentences: what new info would push you above 70% or below 30%\u003e\"\n}\n",

"rationale": "(a) Only about three weeks remain between the question\u0027s opening (Aug 7, 2026) and the Sept 1, 2026 resolution date, and the stated decision point \u2014 a \u0027late August\u0027 launch management committee \u2014 falls right at the edge of that window. (b) Status quo: the launch is broadly slated for October (KASA administrator publicly committed to \u0027late October\u0027), thruster fixes are reportedly complete but verification testing was still ongoing in early August, and the committee is scheduled but not confirmed for a specific late-August date; if nothing changes, the committee likely meets and may announce either a firm date or just a window. (c) NO scenario: the committee slips into early September (Chuseok/verification test delays), or it convenes but only confirms \u0027October\u0027 / a launch window (\ubc1c\uc0ac \uc2dc\uae30) as Korean reporting suggests, deferring the exact date to a later meeting closer to flight \u2014 historically the exact date has often been fixed only weeks before launch, not two months out. (d) YES scenario: verification testing completes, the committee meets ~late August as announced and, following prior practice of fixing an exact launch date and time window, publicly names e.g. a specific late-October date, widely reported by Yonhap/JoongAng. Given three prior slips (June\u2192August\u2192September\u2192October) and explicit reporting that the meeting will settle the \u0027timing\u0027 rather than necessarily an exact calendar date, I lean slightly below even odds.",

This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question\u0027s resolution could have been known before this question opened, then this question will be annulled.",
