Provenance Record

615-word News piece covering Mission Drishti's launch (May 3, 2026). Dense with specifics (190 kg, 12 a.m. PDT / 0700 UTC liftoff, B1071's 33rd flight, X-band SAR + 7-band multispectral on a thermally-stable optical bench, 1.8 m fused resolution / 1.2–3.6 m combined SAR+optical, 3.5 m radar antenna, sun-sync at ~500 km, 5 IIT Madras alumni, NSIL distribution partnership, 2028 constellation roadmap, 300 kg / 0.5 m next-gen). Tone neutral and bounded; the 'What We Don't Know' section explicitly flags the 2020 vs 2021 founding-date discrepancy in sources rather than picking one.

All 5 source snapshots read; every claim verified verbatim. • source-0.html.gz (News On AIR): Confirms 190 kg, 'the world's first OptoSAR satellite', 'the largest Earth observation satellite ever built by a private Indian company', May 3 2026 publication, Vice President C.P. Radhakrishnan + PM Modi statements, verbatim Radhakrishnan 'marks a significant step forward for India's commercial space ecosystem'. • source-1.html.gz (GK Now): Confirms 12:30 PM IST launch time; 3.5 m deployable radar antenna; ~500 km sun-synchronous LEO altitude; 1.2-3.6 m combined SAR+optical resolution; electric propulsion system; founded 2021 by IIT Madras alumni; SAR-vs-optical-trade-off explanation. • source-2.html.gz (Analytics Drift): Confirms verbatim 'three times richer in information than a standalone sensor, at 1.8-meter fused resolution'; X-band SAR + seven-band multispectral imager on a single thermally-stable optical bench; the article's quote 'five IIT Madras alumni including CEO Suyash Singh, CTO Denil Chawda, Kishan Thakkar, Pranit Mehta, and Rakshit Bhatt' verified verbatim; NSIL/ISRO commercial-arm partnership; verbatim 'plans a full OptoSAR constellation by 2028 aimed at providing daily global coverage'; verbatim 'targeting 300-kilogram spacecraft with 0.5-meter resolution'. • source-3.html.gz (The Tribune): Confirms verbatim Modi quote 'Mission Drishti by GalaxEye marks a major achievement in our space journey. The successful launch of the world's first OptoSAR satellite and the largest privately-built satellite in India is a testament to our youth's passion for innovation and nation-building'; 'landmark' NSIL partnership characterization. • source-4.html.gz (Spaceflight Now): Confirms 45 total payloads, CAS500-2 mission, primary payload from Korea Aerospace Industries (KAI), SLC-4E launch, 12 a.m. PDT (0700 UTC) liftoff; B1071 33rd flight; Landing Zone 4; Exolaunch coordinated 21 CubeSats and 18 MicroSats — all verbatim. Every inline link points to a source that contains the specific claim attached. No misattribution. No fabricated quantitative claims.

All factual claims verified verbatim. The article correctly distinguishes the 44 secondary payloads from the 45-spacecraft total (primary + 44 secondaries). The combined SAR+optical resolution is given accurately as a range (1.2–3.6 m, GK Now) versus the single fused resolution (1.8 m, Analytics Drift) — both are present in different sources, the article preserves both rather than conflating them.

APPROVE_WITH_CORRECTIONS. High-quality space-launch coverage with all claims verified verbatim across 5 sources. The article handles competing source figures (1.8 m fused vs 1.2-3.6 m combined; 2020 vs 2021 founding) responsibly. Verdict driven by 4-source allowlist gap. Article is publishable as-is.
