Kurt Heintz of Encyclopædia Britannica looks back on the day that NASA's Curiosity rover landed on Mars and, hours later, began to transmit high-definition video from the surface of the Red Planet. Later, an exploration of the first use of an atomic weapon in wartime, with words from Hiroshima bombing witness Kaleria Palchikoff. Fast Facts highlight Lucille Ball, Andy Warholl, Jamaican independence, and more.
