Why YSK: It’s a fascinating and lesser-known Cold War story that shows just how bold and creative real-world espionage operations could be—and how they can influence global events like the Space Race. It’s also a reminder that what seems impossible might not be, with the right planning and nerve.

This operation, known as Operation Lunik, involved CIA agents (with help from Mexican intelligence) disassembling a Luna 2 moon probe on display at a Soviet exhibition in Mexico City—photographing it in detail, and putting it back together overnight. The Soviets never noticed a thing. This gave the U.S. valuable insights into Soviet space tech at a critical time.

If you’re into history, tech, or spy stories, this one is worth knowing.
