How Spacecraft Fly

How Spacecraft Fly by Graham Swinerd is defiantly a really good book that introduces you to space and the history and theory behind it. Also you don't have to have a technical background to understand it. I'm currently reading it and even though I do have a technical background and understanding I do find this book appealing and helpful.

I really like the way he explains theoretical concepts and adds casual jokes to lighten the mood. Defiantly a good read to get you into the Space state of mind.
