1. Power Rangers In Space introduced us to New Red Ranger Andros, played by Christopher Hayman Lee.  Melody Perkins jioned the cast to replace  Hillary Shepard Turner's Divatox character. She played the villianess Astronoma. All past pr villans would make cameos in Space for the most part, as well as their Master Dark Spector. Bob Manhahan would make cameos as Zordon as well.  Later on Justin Nimeo, would play Zhane, the Silver Ranger . PRIS would gets its footage from Megaranger.

2.  PRIS is home to the first  and only cross over between the Teenage Mutant Ninja Turtles and Power Rangers.

3.  Johnny Young Boshe would return for a guest apearance during space. This could have been in part to show apreciation for agreeing to stay for the rest of turbo before he was dropped.

4.  Power Rangers In  Space seemed to shift Power Rangers to a more serious tone. This could be attributed to new story editors Judd Lynn and Jackie Merciand. Judd later claimed that the first thing he did after taking over the story editor job mid turbo was  fine tune some of the writing. This invloved him writing many episodes of the series  himself for the remainder of his run on the show. This is unparallelled in the tv business. Jackie Merciand also carried  a big load The producer, Johnathon Tazchar had obtained sole showrunner power over the show. That heavily attributed to the new direction as well.. Trazchar wasn't a writer but always was there to run  the show .

5.   Countdown to Destruction aparantly was originally supposed to be a three parter. Aparently the original version would have had Andros and Ashley kiss on screen. There also would have been a battle between Zhane and Elgar. Some think the idenity of the Phantom Ranger would have been revealed, but no such scene was ever filmed.  It wouldn't have been anyone we know just a stunt actor. Some say the Phantom Ranger was the essense of every Power Ranger. Their is no clear cut answer to what the Phantom really was other than he is not a past Ranger.  He was just  some random do gooder from Eltar.

6.  Countdown to Destruction can be seen as a major turning piont for Power Rangers. It cleaned up past storylines and set the stage for a complete start over. It was probably the most epic thing ever tried in the show's history up to that piont. It set up the traditional end of season fanile PR would have ever year after. It  also made Space the first Power Rangers season to have biginning, middle, and end. All this set the tone for the sentai like  method of changing casts every year.
