ISS power output increases to at least 215 kilowatts following final roll-out solar array checks.

Question

Six frontier AI models put this at 86% by 8 Feb 2027. Full reasoning from every model.

WillHappen.ai · Accepted Answer

86% — the median of 6 frontier models, resolving by 2027-02-08.

Answer

Gemini (Google): 88% — NASA engineering verification of the fully deployed iROSA suite hinges strictly on routine telemetry and sun-tracking alignment. All hardware is physically installed, leaving only post-deployment checkout and power telemetry integration by early 2027. Prior iROSA pairs reliably delivered targeted 28 kW boosts without array degradation or major electrical bus anomalies. A failure to verify would require multiple array drive failures or severe micro-meteoroid damage within the next three months.

Answer

Claude (Anthropic): 78% — Hinges on whether final iROSA array performs to spec during post-install verification by Feb 2027. NASA has successfully completed and verified 5 of 6 iROSA installs already, establishing a strong track record for this hardware. Final array installation and testing just needs to complete within the ~3 month window, which is plausible given ISS schedule cadence. Main risk is schedule slip from EVA delays, visiting vehicle conflicts, or minor degradation shortfall below exact 215 kW threshold.

Answer

GPT (OpenAI): 89% — It mainly depends on routine on-orbit commissioning confirming the already installed arrays’ expected output. NASA and its ISS partners must complete telemetry review and formally report post-installation performance before 8 February 2027. All six iROSAs were installed by 2023, so this is verification of operating hardware rather than a new launch or installation. Comparable ISS array commissioning usually succeeds; a major degradation, power-channel fault, or delayed public confirmation would change this.

Answer

Grok (xAI): 84% — Post-install iROSA checkout data must confirm the 215 kW total before Feb 2027. NASA finished the sixth iROSA in 2025; remaining work is only array checkout and telemetry review by ISS ops. Prior iROSA pairs met or exceeded predicted output, so the 55 kW increment from 160 kW is the expected baseline. A public under-performance report or delayed data release would drop the odds; none has appeared by Nov 2026.

Answer

DeepSeek (DeepSeek): 88% — The hardware is already installed; this hinges on NASA publishing post-installation power data confirming 215 kW. NASA completed the final iROSA array installation in 2025, so the physical capability to reach 215 kW already exists on orbit. The remaining step is post-installation testing and data release, which NASA typically completes within months of hardware checkout. The 215 kW figure is a design specification already met by the deployed arrays; only formal verification reporting remains, and no technical failure has been reported.

Answer

Qwen (Alibaba): 79% — All six iROSA panels were installed by mid-2023; the question is whether verified output meets the 215 kW design target. All six iROSA panels were installed by June 2023, giving over three years for post-installation testing and verification before the Feb 2027 deadline. The 215 kW figure was NASA's stated design goal for the augmented array; actual output could fall slightly short due to degradation or thermal derating, but margins were… A development that would lower this: if ISS power management issues or array degradation led NASA to report a lower sustained figure, or if formal confirmation remains…
