Provenance Record

Well-structured News piece (600 words, within the 400-1200 News range). Clear sections (Overview, What We Know, What the Images Show, Why It Matters, What We Don't Know) and appropriate technical depth for a mission-update story. Correctly frames this as the delivery of results promised by the June 24 setup piece, with a link back to that prior coverage.

All 5 source snapshots were decompressed from sources/2026-07/<slug>/ and read from disk (no re-fetch). source-0.html.gz (JAXA press release, July 6, global.jaxa.jp) CONFIRMED: the flyby quote 'On 5 July 2026 at 18:30 JST (error margin: +/-1 second), Hayabusa2 successfully performed a flyby of Torifune' verbatim; the '18:35 JST ... confirmed from ground communications to be operating normally' claim; the ~10 km TIR imaging distance; release of both the ONC-T optical and TIR thermal images; and the 'only part of the data ... has been transmitted to Earth. The remaining data will be transmitted to the ground during future operations' quote verbatim. source-1.html.gz (Space.com) CONFIRMED: 1,475-foot (450-meter) size, 62 million miles (100 million km) from Earth, the 'much cooler in what appear to be shadowed regions ... much warmer where the surface faces the sun' TIR quote verbatim, and the 'two-headed' characterization. source-2.html.gz (EarthSky) CONFIRMED: 6 miles (10 km) distance; the 'two rubble piles joined together, or what astronomers call a contact binary' quote verbatim; the 'gray body with two roundish lobes and a narrow waist covered in small bumps' description (drawn from EarthSky's image alt text 'Gray rock object with 2 roundish gray lobes and a narrow waist, totally covered with small bumps'); and 'JAXA is still acquiring this data, so expect more revelations.' EarthSky did NOT support the 'enter orbit and attempt to land on the surface' detail attributed to it (see findings) — it says only that Hayabusa2 'should arrive at the asteroid in 2031.' source-3.html.gz (The Debrief) CONFIRMED: 'traveling at speeds approaching 5 kilometers per second' verbatim, the 1998 KY26 visit 'expected to occur in 2031,' and the planetary-defense/deflection framing; it contains no orbit/landing language for KY26. source-4.html.gz (JAXA press release, June 9) CONFIRMED: the 'acquire fundamental data for the technology required to accurately guide a probe to impact with small celestial bodies' quote verbatim and the ~5 km/s planned flyby velocity.

Central thesis is fully sourced: the completed July 5 flyby, ~10 km closest imaging distance, ~5 km/s velocity, 450 m size, two-lobed contact-binary finding, ONC-T/TIR instruments, thermal contrast, and 2031/1998 KY26 rendezvous all trace to cited sources. Critically, the 'contact binary' characterization is attributed to EarthSky and Space.com, not overstated as a JAXA conclusion — JAXA's own release does not use that term. The article correctly distinguishes the planned ~1 km flyby (June 9 release) from the ~10 km actual imaging distance (July 6 release) without conflating them. One subordinate claim ('enter orbit and attempt to land on the surface' at the 2031 KY26 rendezvous) is misattributed to EarthSky, which does not support it; filed as a correction.

High-quality, well-sourced update that delivers the genuinely new results of the Torifune flyby. All headline, summary, and lead claims are sourced and correctly attributed to JAXA and secondary outlets without overstatement. A single misattributed subordinate detail warrants APPROVE_WITH_CORRECTIONS so readers see a public corrections trail; it does not touch the central thesis and is not severe enough to reject.
