The study team recommends that NASA adopt a rigorous, evidence-based scientific approach to UAP, leveraging open-source data, AI/machine learning for anomaly detection, calibrated sensors, and crowdsourced observations while reducing reporting stigma. It emphasizes the need for high-quality, multi-sensor data with proper metadata and calibration rather than relying on anecdotal reports. The report notes that current data on UAP is insufficient for scientific conclusions about their nature or origins and does not evaluate specific historical incidents or endorse claims of non-human intelligence. It positions NASA as a supporting partner in broader government efforts led by AARO, focusing on advancing transparent, reproducible scientific methods for future observations.
