Full analysis：Will the Roman telescope enter its L2 orbit before 2027?
Event Details
NASA launched Roman on August 30 and plans orbital insertion roughly 100 days afterward. Opening 85%: a roughly 100-day journey from August 30 points to early December, with the first course correction complete and about three weeks of margin; deep-space maneuver and schedule risks remain. Yes only if NASA's mission log confirms Nancy Grace Roman Space Telescope completed insertion into its Sun–Earth L2 halo orbit by 11:59 p.m. UTC December 31, 2026. Otherwise No. Approaching L2, a planned maneuver, or engineering tests do not count; leave pending while official evidence is unavailable.
