    "body_text": "A Southwest Research Institute-led study links the breakup of the Eulalia asteroid family's parent body near a Jupiter-controlled orbital gateway to a surge of impacts recorded on the Moon. Because Earth's active geology erases very old craters, the lunar record and asteroid dynamics provide indirect evidence for debris reaching Earth and Mars. Possible climate or biological consequences remain hypotheses; the paper chiefly supplies a plausible source and delivery route for the bombardment.",
