Advancing Interstellar Science: A Global Framework for Comprehensive Study of Interstellar Objects

The operation of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) marks a transformative moment in humanity's capacity to detect and characterize interstellar objects (ISOs). With projections indicating an increase from a few detections per decade to potentially one every few months, humanity stands at the threshold of unprecedented scientific opportunity offering revolutionary insights into the nature of rocky materials, building blocks of life and technological products from other star systems. This white paper proposes the establishment of the United Nations Committee on Interstellar Objects (UNCIO), a specialized body designed to coordinate global scientific research, maximize observational coverage, and ensure optimal scientific return from these extraordinary objects from outside the solar system through systematic investigation in cosmochemistry, astrobiology, planetary sciences, fundamental physics, advanced technologies and materials science. The proposed framework addresses critical gaps in our current international infrastructure: the absence of coordinated detection, classification and intercept capabilities, insufficient protocols for rapid scientific response and international policy decisions to time-sensitive observations, and the need for effective science communication to maintain government and public support for these ambitious investigations and global threats to Earth. Drawing from successful international collaborations in areas such as the International Space Station (ISS) and the European Organization for Nuclear Research (CERN), UNCIO would operate through a dual structure: an executive board for time-critical scientific decisions and an expanded committee for comprehensive stakeholder representation. This initiative is not merely aspirational but urgently practical.
