The Roman Space Telescope reaches its operational orbit by November 30, 2026.
NASA launched the Roman Space Telescope on August 30, 2026, embarking on a three-month cruise. Success requires the spacecraft to reach its designated operational orbit approximately one million miles from Earth by late November.
Across 5 frontier models answering independently, the panel treats this as close to settled: the median is 88%.
They broadly agree, 11 points between DeepSeek at 92% and Gemini at 81%.
Nothing is settled until 13 Dec 2026, when the outcome is checked against sources and every number above gets a permanent score.
