SpaceX CRS-35 payloads begin their planned multiweek ISS research runs following an October 2026 launch.

Question

Six frontier AI models put this at 71% by 16 Nov 2026. Full reasoning from every model.

WillHappen.ai · Accepted Answer

71% — the median of 6 frontier models, resolving by 2026-11-16.

Answer

Gemini (Google): 68% — Success hinges on Falcon 9 avoiding autumn manifest slips that push launch past late October. Cargo Dragon missions boast high execution reliability, but ISS docking traffic and Falcon 9 cadence routinely slip by weeks. If launch occurs by late October, berthing and initial experiment checkouts typically commence within 3 to 5 days of arrival. A single technical abort or pad refurbishment delay pushing liftoff into November would leave insufficient run time by Nov 16.

Answer

Claude (Anthropic): 70% — Hinges on CRS-35 launching on schedule and payload checkouts starting without major anomalies. SpaceX Dragon cargo missions to ISS have a strong track record of successful launch and berthing within days of target dates. Research runs typically begin promptly after delivery per NASA's standard payload integration timeline, barring docking delays or vehicle issues. Main risk is schedule slip from launch scrubs or ISS traffic conflicts pushing initiation past the resolution window.

Answer

GPT (OpenAI): 81% — The key hinge is whether CRS-35 launches and reaches ISS promptly enough for payload activation before mid-November. Cargo Dragon missions usually launch within weeks of schedule, but weather, Falcon 9 issues, or ISS traffic can cause slips. SpaceX must launch, rendezvous, berth, and NASA crews must activate the experiments; these are routine operations after a nominal docking. A launch hold extending beyond roughly 30 days, as occurred on occasional CRS missions after technical findings, would most change the outlook.

Answer

Grok (xAI): 62% — CRS-35 must launch in October and berth so experiments start by 16 Nov. NASA mid-Oct target from 17 Oct leaves 14 days; SpaceX CRS historically slips 1-3 weeks ~40% of the time. Berthing plus crew handover typically starts runs in 3-7 days, fitting a late-Oct launch. A Falcon or ISS anomaly after 31 Oct would miss both the October-launch clause and the 16 Nov cutoff.

Answer

DeepSeek (DeepSeek): 72% — Whether CRS-35 launched on its mid-October slot and the experiments actually started running aboard ISS. NASA's CRS-35 was slated for mid-October 2026; by Oct 17 the launch window is essentially now, so success hinges on a clean Falcon 9/Dragon ascent in days. Cargo Dragon berths ~1-2 days after launch and crews typically activate payloads within days, leaving ample margin before the Nov 16 deadline. Historical CRS missions slip roughly 20-30% of the time from schedule, but once at the pad with a firm date, on-time launch odds sit near 80%.

Answer

Qwen (Alibaba): 89% — CRS missions succeed ~97% of the time and Dragon docks within 36 hours; the Nov 16 window absorbs minor scrubs. SpaceX CRS has ~97% mission success since 2012 (one loss in 30+ flights), and Dragon typically berths within 1–2 days of launch. Even a 5–7 day scrub from mid-October still leaves ample time before Nov 16 for docking, hatch opening, and payload activation. A catastrophic failure or multi-week stand-down (e.g., an anomaly triggering a fleet-wide hold) is the only scenario that breaks this; that's a ~3–5% tail.
