A strange little side quest
A quick detour while Space Challenge waits for your next move: Humans did not see the Moon's far side until a Soviet spacecraft flew past it in 1959. The timeline takes another interesting turn: Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. So a round of Space Challenge is not just a quick distraction; it is a tiny stop on a much longer space timeline.
