This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.   During its maiden voyage in May 1962, a Centaur upper stage rocket, mated to an At l a sb o o s t e r, exploded 54 seconds after launch, engulfing the rocket in a huge fireball. In ve s t i g a t i o nre vealed that Centaur\'s light, stainless-steel tank had split open, spilling its liquid-hyd rogen fueld own its sides, where the flame of the rocket exhaust immediately ignited it. Coming less thana year after President Kennedy had made landing human beings on the Moon a national p r i o r i t y, the loss of Centaur was regarded as a serious setback for the National Aeronautics and Space Administration (NASA). During the failure investigation, Homer Newell, Di rector of Space Sciences, ruefully declared: Taming liquid hydrogen to the point where expensive oper-ational space missions can be committed to it has turned out to be more difficult than anyone supposed at the outset.
