Possibly the best book I've had to read while studying a Masters in International Relations. So good, that I've actually read it twice (though skimmed a few bits the second time - it's long and tad bit flowery in parts).McDougall has done a fantastic job in digging into the story behind the space race, starting back in 1800s. He shows how Russia, pre-Soviet era, had a significant number of people dreaming of missions into space, which the USSR inherited.He also shows how the US realized one of the key, if not the key, benefit of satellites would be spying on others - and this required a regime that allowed satellite overflight of foreign countries. Which explains why the US chose only it's 3rd best group of rocketeers to compete to launch a satellite.Unfortunately, again as McDougall explains, the US kept this decision very, very secret and did nothing to explain this to the US public, so it badly lost the PR game when the USSR launched Sputnik.I could go on - so many interesting facts, useful to any student of great power politics and invaluable to students of space.
