"Kilroy was here" is an American popular culture expression that is believed to have originated during WWII, when a US shipyard worker began scrawling the phrase on ships he had inspected. US servicemen then took up the saying and began scrawling it all over the world, wherever they were stationed or encamped. The phrase is usually paired with a doodle of a man peeking over a wall, a cartoon that was likely adopted from UK wartime graffiti that was often accompanied by what slogans?

Following the launch of the Soviet satellite Sputnik I in October 1957, there was a frenzied effort by the US to launch a satellite of its own, beginning the so-called Space Race. Launched in January 1958 as part of the US program for the International Geophysical Year project, Explorer-I was the first Earth satellite of the US. It contributed to the discovery of the Van Allen Belts but stopped transmission of data when its batteries died in 1958. It remained in orbit, however, for how long?
