NASA closes the astronaut application window on December 3, 2026.

Question

Six frontier AI models put this at 91% by 10 Dec 2026. Full reasoning from every model.

WillHappen.ai · Accepted Answer

91% — the median of 6 frontier models, resolving by 2026-12-10.

Answer

Gemini (Google): 88% — NASA rarely extends USAJOBS application windows unless technical outages occur during the final application surge. NASA set the Dec 3, 2026 deadline in its formal announcement and standard federal hiring rules favor strict closing dates. Federal portal extensions typically only happen if severe USAJOBS server failures or natural disasters block access near deadline. A formal extension notice by OPM or NASA due to technical delays would immediately invalidate this schedule.

Answer

Claude (Anthropic): 93% — NASA application deadlines almost always close on the posted date absent rare administrative extensions. NASA has a long track record of closing astronaut application windows precisely on the announced deadline. No action is required from NASA beyond routine portal closure, which is an automated/scheduled process. Only a government shutdown, system failure, or unusual extension announcement would change this, which is uncommon but not impossible.

Answer

GPT (OpenAI): 96% — It hinges on NASA maintaining a routine, already-announced application deadline over the next 23 days. NASA’s Astronaut Selection portal gives applicants until 11:59 p.m. EST on December 3, leaving little approval work to do. Federal recruiting windows overwhelmingly close as posted; extensions usually follow outages, legal changes, or a recruitment shortfall. A major USAJOBS/NASA portal outage near December 3 would be the clearest reason NASA might extend rather than close it.

Answer

Grok (xAI): 87% — Whether NASA extends the posted Dec 3 11:59 p.m. EST cutoff or the portal stays open. NASA publicly set a hard close; astronaut selections historically keep announced windows and already draw thousands of STEM applicants. No extension notice has issued by 10 Nov, and any change would need a visible USAJOBS/NASA announcement first. Only a last-minute portal outage or unexpectedly low volume would force a delay, both low-base-rate events.

Answer

DeepSeek (DeepSeek): 97% — NASA's portal closing on a posted deadline is routine; only a shutdown or portal failure would derail it. NASA published the Dec. 3, 2026 11:59 p.m. EST cutoff and the USAJOBS-style portal is already live, so no new action is needed. Past astronaut calls (2020, 2024) closed on their announced dates; extensions are rare and usually announced weeks ahead, not in the final 23 days. A government shutdown starting Dec. 1 could freeze the portal, but the current CR runs into 2027, making that the main tail risk.

Answer

Qwen (Alibaba): 89% — NASA has extended astronaut application deadlines before (2024 cycle), but the default is that announced dates hold. NASA extended the 2024 astronaut application window by ~2 weeks, showing extensions are a real but minority outcome. No government shutdown or major disruption is currently forecast for early December 2026 that would force a delay. A last-minute extension due to low applicant volume or portal issues would be the main surprise; historically this happens ~10-15% of the time.
