As someone who read up on the US space program as a kid, especially reading over and over the National Geographic issues at my great aunt's house. As an adult, I can go deeper into the US stories to learn the ups and downs, the characters that became national heros flying out into the black.
More recently is an interest in the Soviet space program at the same time. It can be hard to separate the men and the myths. Especially from the Soviet era. But there are authors who have pierced the veil to give the Soviet efforts their due.
Here is a biography of Korolev, the mastermind behind Soviet rocketry & space efforts. The author has taken great strides in getting at Soviet archives and interviewing people directly involved in the space program, including his daughter. Those interviews are just gold, as they help paint a portrait of a man on who's shoulders rode many mankind firsts. Be forewarned, though. This book can be dry in places. The writing more academic at times. You will probably get lost in all of the names. But at the end, I feel you'll know have a greater appreciation for what he had to overcome.
From the book, I have a greater appreciation of just how crazy their space program was at the time. With rudimentary computer hardware and heavy electronics, they were able to automate quite a bit. These days we'd run software on processors, but in those days there wasn't a Space OS. The Soviets were big on automating as much as possible and testing it that way before putting men in the loop. But at the same time, they cut corners in order to be first. My take is that the firsts were more one-offs in order to claim the achievement than the stair step method of incremental expansion of the envelope. Korolev tried to deal with this knowledge debt, but with a severely limited budget, overworked people and a NASA Apollo effort that tapped into country wide talent, he could never have one the race to the Moon. (The Soviet effort was super secret, so less sharing of data & hiding of failures from the public)
The outcome of the Soviet program was a family of launchers that still operate today. They are super reliable, though not as technically elegant as former NASA designs.
With this book done, I have two more on the Soviet programs, especially around the N-1/L-1.
