Part of a new Space Innovationso series, this volume joins others on satellites, robot explorers, and a discussion of space exploration. Here Miller describes the history of rocket science, beginning in ancient China, where saltpeter, sulfur, and charcoal were first combined to create gunpowder. Although the Chinese tried to use gunpowder and rockets in warfare, inability to aim kept them from being truly useful as weapons, relegating them to being used largely for entertainment. Europeans were using gunpowder as early as 1249 but had similar problems adapting it to warfare. As time and technology progressed, though, rockets and gunpowder played a crucial role in war.
