The report emphasizes that NASA can play a prominent role in the whole-of-government UAP effort by leveraging its expertise in Earth observation, data analysis, AI/machine learning, and sensor calibration to build a robust, evidence-based dataset. It recommends reducing stigma around UAP reporting, developing a crowdsourced civilian data pipeline (e.g., via smartphone apps), improving calibration and metadata standards for observations, and collaborating with agencies like the FAA. The team found no evidence in available data suggesting UAP represent extraterrestrial technology or pose national security threats beyond aviation safety. The study explicitly avoids analyzing individual historical cases or claims of non-human intelligence, focusing instead on scientific methodology for future understanding. NASA subsequently appointed a UAP research director.
