In 2017 NASA and the U.S. Energy Department's National Nuclear Security Administration (NNSA) signed an agreement to cooperate on planetary defence — protecting Earth from asteroids and comets — with NASA as the lead agency.[1]

The agreement

Under the arrangement, NASA contributes planetary science and mission design, while the NNSA contributes computer modelling of energetic events and laboratory experiments. NASA scientists work with counterparts at the NNSA's Lawrence Livermore, Los Alamos and Sandia National Laboratories, studying ways to deflect or disrupt asteroids, including nuclear devices as a last resort. According to Physics Today, some officials had feared the labs might use the program as a pretext to resume nuclear testing, and the agreement was meant to address that concern.[1][2]

NASA had opened its Planetary Defense Coordination Office in January 2016 and also ran joint impact-response exercises with the Federal Emergency Management Agency. In September 2022 its DART mission changed the orbit of a small asteroid by crashing a spacecraft into it, the first test of the technique.[3][4]

The testimony notes that nothing in the public record suggests the planetary defence work is UAP-related, but suggests that the NNSA office that funds research might house some UAP-related research. There is no evidence for that.
