On August 20, 1968, the Soviet Union led a massive Warsaw Pact invasion of Czechoslovakia, deploying 200,000 troops and 5,000 tanks to crush the liberalizing reforms known as the Prague Spring. This episode of Deep Dive explores the tragic end of Alexander Dubcek’s vision for socialism with a human face and the brave, non-violent resistance of the Czechoslovakian people. We also commemorate the birthdays of three diverse icons: 23rd U.S. President Benjamin Harrison, cosmic horror legend H.P. Lovecraft, and pioneering journalist Connie Chung. The narrative concludes with a look toward the stars, recounting the 1975 launch of NASA's Viking 1, which eventually became the first mission to successfully land and operate on the Martian surface. Through these stories, we examine the tension between control and discovery that defines the human experience.
