Question: So does Rita Repulsa die when she goes into space? It seems unlikely she could survive mainly without oxygen.
Rob245Answer: No, she's not dead. This show seems to be following similarly to the original TV show. In the show, she was in a stasis like state trapped in a "trash can" on the moon. After she escapes this prison, she sets up her evil base with Lord Zed on the moon and continues to attack Angel Grove and the Rangers from the Moon. So her being blasted towards the Moon at the end of this reboot is a set up for her establishing a similar base of operations like in the show in the sequels. If the sequels ever get out of development hell.
