Lost Galaxy was an adaptation of Seijuu Sentai Gingaman, whose name meant Starbeast Squadron Galaxyman, but the season was not space-based. The Gingaman team themselves were members of an ancient tribe from a mystical forest, empowered by Starbeasts from space to protect the Earth from destruction by a band of evil space pirates. The makers of Power Rangers had gone ahead and developed a space-based premise based on their expectations from the title, so they were surprised when they saw that the actual show was Earthbound -- similarly to what had happened the previous year with the adaptation of Power Rangers in Space from Megaranger, in which the organization the team worked for operated from a spaceship but the show was about a group of high school students in Tokyo. So PRLG ended up with a radically different storyline from Gingaman (aside from the Magna Defender arc, which was almost verbatim).
So whatever PRLG did with its depiction of galaxies in space was its own fault, not a matter of translation.
Could a translation concern have played a role here?
