🌕 On July 20, 1969, Apollo 11 landed on the moon. The mission marked a giant leap for space travel and measurement science. From calculating escape velocity to machining parts with thousandths-of-an-inch tolerances, metrology made the mission possible.

Even navigation relied on precise inertial guidance systems, calibrated to stay accurate in zero gravity. Every bolt, burn, and broadcast depended on trusted measurements. And 55 years later, metrology is still pushing boundaries on Earth and beyond.
