Good morning, investigators. Today the smallest proposed clue sits inside the largest available evidence locker: lunar soil. A SETI team calculates that durable engineered grains could cross interstellar distances and accumulate in the Moon's unusually stable surface, then gives future sample-return missions a concrete test instead of announcing a discovery that did not happen. Two orbital studies sharpen the identification toolkit from opposite directions. One shows that moonlight and light bounced from Earth can keep the ISS and other large satellites optically visible long after the usual sunlit window; another publishes maneuver labels checked against several tracking sources. A fireball calibration paper reaches the same methodological conclusion at higher speed: a catalog can nominate an interstellar candidate, but only an independent three-dimensional trajectory with uncertainties can secure the classification. Beyond Earth, incoming dust may help create silicate clouds, while freezing and melting at an ocean world's ice edge may concentrate prebiotic ingredients. The board is full of plausible mechanisms and empty of confirmed extraterrestrial artifacts—which is exactly how a useful research morning should look.
