The Nancy Grace Roman Space Telescope reaches its final operational orbit within three months of launch.
The Roman Space Telescope undergoes a three-month transit to reach its destination orbit, usually around the Sun-Earth L2 point, following launch.
Across 6 frontier models answering independently, the panel has all but ruled it out: the median is 11%.
They do not agree: GPT puts it at 94% and Gemini at 4%, 90 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Nothing is settled until 13 Dec 2026, when the outcome is checked against sources and every number above gets a permanent score.

L2 transfer is designed for roughly 90 days; only a major launch or spacecraft anomaly would prevent it.

Launch slips dominate; 3-month transit plus commissioning rarely lands inside a 3-month window.

Roman's launch has slipped for years; unlikely to even launch by mid-2026 let alone reach L2 within 3 months by Dec 2026

Roman launch is targeted for late 2026 to mid-2027; reaching orbit by Dec 2026 is extremely unlikely.
