John Foster writes that this work and Law's Through Space to the Planets 'are of historical interest, even if they might not pass Egoff's test for true science fiction stories. The protagonists are a twenty-one-year-old spaceship pilot and his two young brothers, one of whom accidentally wrenches at the controls and send the ship into outer space. Law totally ignores every aspect of scientific possibility, for her characters, flying randomly through space, soon land safely on an unknown planet, which has breathable air and is inhabited by "queer humans" (Through Space to the Planets 23) [...] Rangers of the Universe merely lists their many exploits before their return home' ('Australian Science Fiction for Children and Adolescents: 1940-1990' 85-86).
