99 days out. The optics have to outgas and cool to 95 K before the focal plane can take a science exposure — there is no way to hurry it.

Roman survey data carries no proprietary period. Every product becomes public the moment it clears the pipeline — yesterday after downlink.
Provisioning schedule
Every activity between liftoff and the start of science operations. Phases overlap — outgassing runs for six weeks underneath everything else.
The observing program
Roman's 300.8-megapixel Wide Field Instrument images 0.281 square degrees at a time — a hundred times Hubble's field at the same resolution. The gallery already holds the full planned program; entries fill in with real products as the schedule reaches them.

Preview imagery is procedurally generated from each field's position and crowding. It is a stand-in, not sky data — Roman has not yet opened its aperture cover.
