The FOI disclosure contains internal Australian Government communications regarding the discovery of 3I/ATLAS, an interstellar comet detected on July 1, 2025, by the ATLAS survey telescope in Chile. The first document is an email from the Australian Space Agency's People and Culture team to staff highlighting the scientific significance of this third-ever-observed interstellar object—a 11-kilometre-wide comet estimated to be 3 billion years older than Earth, discovered by the newly operational Vera Rubin Telescope capable of generating 20 terabytes of nightly data. The second document is a National Situation Room incident report noting that 3I/ATLAS poses no threat to Earth, will reach closest approach to the Sun around October 30, 2025, and is currently travelling at approximately 60 kilometres per second from the direction of Sagittarius. The documents reflect routine government tracking of significant astronomical events through
