Tom Murphy, a physicist at UC San Diego, is among the scientists who have aimed laser beams at suitcase-sized reflectors placed on the moon by Apollo astronauts and unmanned Soviet rovers. By precisely timing the light's return to Earth, Murphy can measure the distance from here to the moon with millimeter precision.

Still, the most compelling evidence arrived during another event that once evoked irrational fears-on a night when Earth's shadow eclipsed the full moon.
