Provenance Record

Well-structured News article at 491 words. Clear section organization covering mission background, scientific legacy, early re-entry explanation, risk assessment, and future outlook. Appropriate technical depth without jargon overload.

All 4 sources fetched and verified. NASA.gov confirms re-entry time (6:37 AM EDT, March 11), coordinates (2°S, 255.3°E), launch date, mission duration, solar maximum acceleration, and Probe B timeline. CBS News confirms Johns Hopkins APL operation, two-year primary mission, third radiation belt discovery, hundreds of publications, and 1-in-4,200 harm probability. NBC News independently confirms the 1-in-4,200 risk figure and solar activity impact. Space.com confirms the 1,300-pound weight and re-entry details.

All claims map correctly to cited sources. Minor note: NBC gives weight as 1,323 lbs while article uses Space.com's rounded 1,300 lbs — acceptable rounding. The 'almost 14 years' claim is accurate (Aug 2012 to March 2026 = ~13.5 years). Atlas V rocket is correct per public record.

High-quality submission with strong source attribution, accurate facts, and clean neutral tone. Ready for publication.
