This was an entertaining read but not as enjoyable as other sci-fi novels I’ve read. I have to admit I’ve never been a big fan of the “trip to the moon and surrounding planets” sub genre of sci-fi. Still, I wanted to give this book a try as it a classic of its genre and because I recently read (and loved) “Stranger in a strange land”, also by Heinlein. “Have space suit” did feel a bit outdated at times. It’s more of a general feeling than particular details in the book but I could still feel that the book at been written quite some time ago. An interesting read nonetheless!
