Last week, the White House released a “National Preparedness Strategy and Action Plan for Near-Earth Object (NEO) Hazards and Planetary Defense.” The document addresses the hazard of NEO impacts by leveraging and enhancing existing national and international assets and adding important capabilities across government.
Sixty-six million years ago, a 10-kilometer rock impacted Earth and caused mass extinction of 75% of all plant and animal species on Earth, including all non-avian dinosaurs. In 2005, the US Congress tasked NASA to find 90% of all NEOs bigger than 140 meters that could hit the Earth. With its 3.2 billion-pixel camera, the Vera C. Rubin Observatory aims to identify two-thirds of these objects within a decade, complementing the work of the Pan-STARRS telescope in Hawaii, which discovered the first interstellar object, `Oumuamua, after flagging it as an NEO. This discovery, ushering the research frontier of interstellar objects, was highlighted in the White House document.
