### 2. Ignition!: An Informal History of Liquid Rocket Propellants

**Author:** John Drury Clark

A propellant chemist's firsthand account of the Cold War search for liquid rocket fuels, with a foreword by Isaac Asimov. Explains why engineers settled on hydrogen, kerosene and hypergolics, and what made candidates like chlorine trifluoride unusable despite excellent performance.

### 3. Challenge to Apollo: The Soviet Union and the Space Race, 1945-1974 (NASA SP-2000-4408)

**Author:** Asif A. Siddiqi

Asif Siddiqi's 1,000-page history of the Soviet space program, published free by NASA. Built from post-Soviet archives, it documents Korolev's design bureaus, the N1 lunar rocket failures and the political decisions behind Sputnik, Vostok and Soyuz. Corrects the US-centric picture.

### 4. Chariots for Apollo: A History of Manned Lunar Spacecraft (NASA SP-4205)

**Author:** Courtney G. Brooks, James M. Grimwood, Loyd S. Swenson Jr.

NASA's official engineering history of the Apollo spacecraft, free from the technical reports server. Traces the command, service and lunar modules from 1957 through Apollo 11, including the lunar-orbit-rendezvous decision, contractor management and the Apollo 1 fire. The history pick that is actually about engineering decisions rather than personalities — mode selection, weight growth, subcontractor failure, test discipline after the pad fire.

### 5. Fundamentals of Astrodynamics: Second Edition

**Author:** Roger R. Bate, Donald D. Mueller, Jerry E. White, William W. Saylor

The U.S. Air Force Academy's astrodynamics text, revised in a second edition. Derives two-body motion, orbit determination, Lambert's problem, ballistic missile and lunar/interplanetary trajectories from Newtonian mechanics, with worked problems that let you actually compute transfers and delta-v budgets.

**Difficulty:** Advanced | **Language:** English | **Price:** Paid
