I know it was said Mars was far away from Earth, but I think they reached it the same day the left because they used a Klaxosaur spaceship rather than one made by humans, as 001 said the Klaxo sapiens were more technically advanced than humans. Also Hiro02’s souls took longer to each earth because they likely didn’t go through the warp gate; by using the gate, it took them only two years to reach the VIRM planet, which is said to be at the end of the universe.

I think all the adults are aware of sex and reproduction; Nana knew what it was because she warned Kokoro in episode 17 that no one can speak of it let alone do it. Only the kids are kept in the dark because their priorities should be focusing on combat rather than emotions and anything that would distract them.

That being said, I think she was 4-5 weeks and the numbers must have been a miscalculation on part of the writers of episode 22 but maybe the manga will clarify this better.
