This puzzle is an excellent way to introduce science fiction to students. It is an "anacrostic," a puzzle that highlights a long quotation and as well as terms and concepts germane to the puzzle's theme. Students will quickly learn how they work and, if my experience of distributing them to students for twenty years is an indication, will become big fans of them. They can be worked on in class, in pairs or groups or alone and they make an excellent homework assignment. They're easy to grade with a quick scan for completion. They are very effective at getting students to engage with great quotes and they make a wonderful followup to related literature.
