NASA, ESA, and international warning networks are simulating a 19% probability that hypothetical asteroid 2026 PDC27 will strike Earth on 10 July 2038. The exercise tests observation gaps, impact-probability updates, and coordination procedures that would be required to protect civilisation and preserve lunar infrastructure during a genuine threat.
