and extracts the following text as a script body — the dev server then fails its dependency scan with `Expected ";" but found "non"` from the words "non-allowlisted hosts", which breaks e2e. So, what this buys, so nobody reads more or less into it: blocks external `script src=` from non-allowlisted hosts blocks injected inline scripts — each one is pinned by hash blocks fetch/XHR/WebSocket exfiltration (connect-src allowlist) blocks form-action, base-uri, object-src vectors does not stop image-based exfiltration — img-src must allow https: because event media comes from arbitrary publishers' og:image The cost of hashing is that an inline script edited after the hashes are computed is silently refused by the browser. That is why the violation reporter below exists: report-uri/report-to are ignored in a meta element and Pages serves no CSP header, so violations are caught in-page and sent to PostHog instead (src/lib/csp-report.ts, #241). frame-ancestors is deliberately NOT in this string: it is ignored in a meta element and browsers log a warning about it on every page load. It lives in public/_headers instead, ready for a CDN in front of Pages. X-Frame-Options (set there too) is the clickjacking control that actually applies today. */ }

Final RS-25 Engine Delivered to KSC — All Four Artemis III Core Stage Engines Now on Site

| Artemis II

The fourth and final RS-25 engine for the Artemis III SLS core stage arrived at Kennedy Space Center's Vehicle Assembly Building on Tuesday, July 21, 2026, shipped from NASA's Stennis Space Center near Bay St. Louis, Mississippi. All four RS-25 engines — built by L3Harris Technologies and derived from Space Shuttle-era hardware — are now on site; technicians will integrate them with the core stage over the summer. NASA Administrator Jared Isaacman marked the milestone while continuing to publicly push the compressed 'Artemis Acceleration' timeline.
