Nothing memorable. A YA novel where everything goes fine for the protagonists -to the point that even during some crisis, it's always dealt with nochalance, no real sense of danger, no true stakes.
Basically, there is no conflict, and it is comprehensible: Back in 1952, the future was a bright horizon filled with promises, science fiction an unchartered territory of wonders and you didn't want to impress young readers with dark or overdramatic stuff.
As a result, this novel is a constant telegraphing of the next solution in favor of our heroes, it doesn't even care to create a true sense of suspence, of scare, of tension in the group -for example, despite the fact that Chuck, protagonist and stoaway, has automatically reduced, with his presence, the survival means of the marooned crew...well, nothing comes out of it, nothing!
