Provenance Record

Clean, well-structured News piece (674 words, within the 400-1200 News range). The Overview/What We Know/The Science Ahead/What We Don't Know structure leads with what is genuinely new (the firm Aug. 30 date) and explicitly frames the article as a follow-up to the April unveiling, which reported only a broad fall 2026 target. Appropriate caveats in the closing section about a launch date being a target, not a guarantee.

All 4 source snapshots read from disk and verified (manifest.json, all status 200). source-0 (science.nasa.gov Roman blog): confirms 'officially slated to launch Aug. 30, eight months ahead of schedule', engineers 'packing Roman up for a voyage from NASA's Goddard Space Flight Center in Greenbelt, Maryland, down to the agency's Kennedy Space Center in Florida later this month', and the dark-energy/dark-matter/'almost anything from our own solar system to galaxies at the edge of the observable universe' survey wording (verbatim). source-1 (spacepolicyonline): confirms 'Today, it's official — Roman is scheduled to launch on August 30', '8,000 kilogram (18,000 pound) telescope', 'SpaceX Falcon Heavy from Kennedy', 'Roman will join JWST at the Sun-Earth L2 Lagrange point 1.5 million kilometers (1 million miles) from Earth in the direction away from the Sun', coronagraph 'that can block starlight to better see planets orbiting other suns', Isaacman 'has been hinting ever since that it might be in August', and Nicky Fox, 'head of the Science Mission Directorate', credited with 'Roman is ahead of schedule and under cost' (all verbatim/correctly attributed). source-2 (nasa.gov media advisory): confirms 'as soon as early September on a SpaceX Falcon Heavy rocket from Launch Complex 39A', 'witness the arrival and unloading of the space telescope in its transport container at NASA Kennedy's turn basin' (verbatim), and the Pegasus barge from Goddard, Greenbelt, Maryland detail. source-3 (ScienceDaily/NASA Goddard): confirms 'about 100,000 previously unknown worlds', 'nearly 6,300 exoplanets', microlensing 'expected to reveal more than 1,000 worlds', Elisa Quintana title and her 'other galactic habitats' quote, and Robby Wilson 'a postdoctoral fellow at NASA Goddard' with his 'hundreds of millions of distant stars' quote (verbatim). Two quoted spans were paraphrased rather than reproduced exactly (see findings) — substance accurate, fidelity off.

Every number, name, date, and central claim traces to a cited source. Headline, summary, and Overview lead (firm Aug. 30 date, eight months ahead of schedule, barge to Kennedy) are each directly sourced to NASA's own Roman blog and SpacePolicyOnline. No fabricated specifics. The two issues are quote-fidelity, not factual error.

Accurate, neutral, well-sourced follow-up that correctly centers on the new firm Aug. 30 date and resolves its cross-reference to real prior coverage. The only defects are two minor paraphrases presented inside quotation marks, both of which a single corrections record can honestly summarize without affecting the headline, summary, or lead.
