Not my favorite Lem book, but still a good read, if for no other reason than as a kind of backstory for Fiasco, which I consider along with Solaris, as Lem's masterpiece, and which I read first. Fiasco begins on a ice-bound station on Saturn's moon Titan. There is an accident. And Prix along with his would-be rescuer are frozen in stasis. Decades later, the bodies are found, but there are only enough parts to rebuild on man. Moreover, there is memory loss, so we don't know for sure if it is Prix who is resurrected or his would-be rescuer.
I enjoyed this book, but it has more in common with the American space operas of the 1960s, which Lem proclaimed to despise. I'd still recommend it as light read, but you need to be something of a Lem fan to enjoy it today, IMHO. Read Fiasco first, which is truly "speculative fiction" in its highest form.
Also, there's a fascinating Wikipedia page on Stanislaw Lem, with links to in-depth synopses on many of his novels.
