RPOD-50: Curated Dataset of 50 Rendezvous and Proximity Operations Missions (1965-2025)

An open, version-controlled dataset of 50 rendezvous, docking, and berthing missions spanning 60 years (1965-2025) and 8 space agencies (NASA, USSR/Roscosmos, ESA, JAXA, CNSA/CMSA, ISRO, plus commercial servicing providers Northrop Grumman, SpaceX, Boeing, Astroscale). Each mission entry includes timeline, masses where public, GNC system, capture mechanism, granularity classification, and primary-source references with DOIs validated via the Crossref API. Companion to the IAC 2026 paper IAC-26-C2-3-6-x112752, "Computational Simulation of Rendezvous and Robotic Berthing for On-Orbit Servicing: Validation Against Operational Mission Data".
