Power Rangers: In Space has 43 episodes.
The season originally aired in the United States from February 6 through November 21, 1998. It follows Andros and the Space Rangers as they battle Dark Specter, Astronema, and the United Alliance of Evil across Earth and the wider galaxy. The 43-episode count includes the two-part finale, “Countdown to Destruction.”
In Space is especially important in Power Rangers history because it concludes the long-running Zordon-era storyline that began with Mighty Morphin Power Rangers. It also brings together plot threads and returning characters from Turbo, Zeo, and earlier seasons before the franchise moves into Power Rangers Lost Galaxy.
The number can be confused with the episode totals of neighboring seasons or with production and broadcast groupings. In Space is one complete season, not a 50-episode run, and its finale is counted as two episodes rather than one extended installment. The season adapted footage and concepts from the Japanese series Denji Sentai Megaranger.
