The "NASA UAS Detection Act" grants the National Aeronautics and Space Administration (NASA) and its authorized personnel the authority to detect, identify, monitor, and track unmanned aircraft systems (UAS) that pose a credible threat to its facilities and assets. This authority specifically allows for actions such as intercepting communications used to control these UAS, overriding certain existing federal laws to enable these operations. The bill defines "covered facilities or assets" as NASA centers or properties and outlines strict criteria for contractors authorized to use this power, ensuring they are directly contracted, assigned to law enforcement duties, and properly trained. Implementation of this authority requires significant coordination with the Federal Aviation Administration (FAA) , particularly concerning aviation safety, training of personnel, and assessing potential impacts on the national airspace system. NASA must conduct a risk-based assessment of its facilities to evaluate UAS threats, considering factors like potential effects on manned aircraft, airport operations, and wireless communications. The technologies employed for detection and tracking must be drawn from a list jointly maintained by several federal agencies, including the Departments of Justice, Homeland Security, Defense, and Transportation. To safeguard civil liberties, the bill mandates privacy protections, ensuring that the interception and use of UAS communications comply with the First and Fourth Amendments. Such communications can only be intercepted to the extent necessary for detection and tracking, and records are generally retained for no more than 180 days, with limited exceptions for law enforcement. Furthermore, NASA is required to provide semiannual briefings to Congress, detailing its activities, privacy policies, and any identified gaps in laws or regulations concerning UAS threats. This authority is temporary, set to expire on September 30, 2031 , and explicitly does not expand NASA's powers beyond these specified detection and tracking functions.
