This Is Rocket Science: True Stories of the Risk-taking Scientists who Figure Out Ways to Explore Beyond
Gloria Skurzynski
National Kids Geographic
..three, two, one… we have liftoff! From the award-winning author of Are We Alone? comes a title to propel young imaginations far into space. This Is Rocket Science explores the past, present, and future of space travel.The compelling text—vetted by NASA scientists—is a combination of history, science, human drama, and future challenges. Readers learn how fireworks in ancient China developed into the fire arrows used by Genghis Khan; we meet Sir Isaac Newton, Jules Verne, H.G. Wells, and learn how their imaginations shaped rocketry. We revisit the era of Sputnik, the satellite that launched a superpower space race, ending with moonwalks and a rendezvous in space. Finally we look forward to the future challenges of Mars and beyond. We also get a sneak peek at new technologies like space elevators, solar sails, ion propulsion, and more.

INDEX
IN THE 13TH CENTURY THE CHINESE DESIGNED FIRE ARROWS TO USE AS WEAPONS AGAINST INVADING MONGOL ARMIES.

FIRE ARROWS
Some inventions happen by accident. Two thousand years ago, Chinese scientists searched for a way to make people immortal. They mixed chemicals with liquids and drank them, hoping this would keep them alive forever. Instead, they often died quickly because their experiments contained poisons.
One of the main ingredients in those potions was saltpeter, a potassium nitrate compound found in dry caves in southern China. Alchemists (the scientists searching for eternal life) used saltpeter to dissolve ores and minerals. They learned how to make pure sulfur by heating iron pyrite, also known as fool’s gold. And they could easily obtain carbon from coal or charcoal. During centuries of experimentation, the alchemists discovered that if saltpeter, sulfur, and carbon were combined, the mixture would burn.
By A.D. 1040 a Chinese official described three combinations of these ingredients to make three different kinds of weapons: a poison-smoke ball, a bomb that burned, and a bomb that exploded—but not violently. Later experiments showed that when extra saltpeter was added to the three main ingredients, the combination exploded with greater force. This became the earliest form of gunpowder, named huo yao, meaning “flaming medicine.”
Hollow bamboo tubes filled with this early kind of gunpowder exploded spectacularly when thrown into a fire.
