The dramatic inside story of the first four historic flights that launched SpaceX - and Elon Musk - from a shaky startup into the world's leading-edge rocket company.

When Elon Musk was a kid in South Africa, he was regularly beaten by bullies. One day a group pushed him down some concrete steps and kicked him until his face was a swollen ball of flesh. He was in the hospital for a week. But the physical scars were minor compared to the emotional ones inflicted by his father, an engineer, rogue, and charismatic fantasist.

Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. 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. 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 that eventually took men to the moon.

The inside look at how the battle of the space billionaires began and why it matters, Escaping Gravity is former NASA Deputy Administrator Lori Garver’s firsthand account of how a handful of revolutionaries outmaneuvered the system of political patronage and bureaucracy that threatened the space agency. The success of Elon Musk’s SpaceX, Jeff Bezos’s Blue Origin, Richard Branson’s Virgin Galactic, and countless other commercial space efforts were preceded by decades of work by a group of people Garver calls “space pirates.”

War with China is much more likely than anyone thinks. When Athens went to war with Sparta some 2,500 years ago, the Greek historian Thucydides identified one simple cause: A rising power threatened to displace a ruling one. As the eminent Harvard scholar Graham Allison explains, in the past 500 years, great powers have found themselves in "Thucydides's Trap" 16 times. In 12 of the 16, the results have been catastrophic.
