Highly recommend for space enthusiasts. It's well balanced, in terms of the scientific jargon without making it too nerdy. It talks about the processes in place for current space missions contrasting with how it's different for longer missions. Interesting experiments and procedures astronauts go through before getting selected. It talks about various space agencies like NASA, ROSCOSMOS, JAXA, etc, their routines. The food, sleep, poop, and mental health of astronauts in space and some interesting gossip from previous missions.
