NASA maintains its target of landing American astronauts on the Moon by 2028 in its October 23, 2026 update.

Question

Six frontier AI models put this at 59% by 24 Oct 2026. Full reasoning from every model.

WillHappen.ai · Accepted Answer

59% — the median of 6 frontier models, resolving by 2026-10-24.

Answer

Gemini (Google): 88% — NASA has strong bureaucratic incentive to defend its existing 2028 landing window until major flight tests force a delay. Artemis III already formally slipped to 2027-2028, making an additional public delay premature before Artemis II flies. Major press briefings called without an acute launch failure rarely announce slips beyond the existing multi-year target window. A formal concession that Starship HLS or Axiom suits will push the crew landing beyond 2028 would immediately overturn this.

Answer

Claude (Anthropic): 35% — Hinges on whether NASA reaffirms 2028 or slips Artemis III given SpaceX HLS and suit delays widely reported. Artemis III has faced repeated schedule slips from 2025 to 2026 to 2027/2028 due to Starship HLS and spacesuit readiness. NASA has political pressure to keep a Moon-before-China narrative, favoring reaffirmation despite technical risk. Recent GAO and NASA OIG reports suggest internal expectation of further delay, which could lead to a new date being announced instead.

Answer

GPT (OpenAI): 68% — It hinges on whether Artemis hardware and funding setbacks force NASA to publicly slip its already revised 2028 goal. NASA leadership controls the Oct. 23 briefing message, so no external vote or treaty approval is needed before the deadline. Artemis II, Starship HLS, lunar suits, Gateway and SLS readiness must still support the schedule; several have shown delay risk. NASA historically revises Artemis dates after major technical reviews, but a briefing framed around lunar plans suggests it will retain 2028 absent a fresh failure.

Answer

Grok (xAI): 22% — NASA still publicly locking Artemis III to 2028 despite known HLS/SLS slips. Administrator must confirm the date at the 23 Oct KSC briefing; hardware (Starship uncrewed landing, SLS Block 1B) remains the gate. Artemis dates have slipped every 12–18 months since 2022; GAO already flagged 2028 as optimistic, so base rate of holding is low. A completed Starship lunar demo in the next week would be the only near-term event that could keep 2028 on the slide.

Answer

DeepSeek (DeepSeek): 62% — NASA has kept restating the 2028 Artemis landing goal all year, so the October 23 briefing likely repeats it again. Acting administrator Duffy and the Artemis team have publicly reaffirmed the 2028 target repeatedly through 2026, including after HLS schedule slips. The briefing is a NASA-run event at KSC, so the agency controls the messaging and has no incentive to abandon its own published target. Base rate for NASA restating an existing schedule at its own press event is high; only a new GAO or OIG finding of a slip would force a downgrade.

Answer

Qwen (Alibaba): 55% — Political pressure to hold the 2028 date vs. the Artemis program's consistent pattern of schedule slips. Artemis III has slipped from 2025 to 2026 to 2027 to 2028 across successive NASA updates; each prior briefing has pushed the date right. A KSC briefing framed around 'lunar landing plans' more likely signals a confirmation or milestone than a delay announcement, nudging above base rate. Starship HLS uncrewed lunar demo and Orion/ESM integration milestones would need to be on track; any single failure would force a slip to 2029.
