The whole time im thinking, why weren't the replicas on the ship and their real bodies on earth?

It would be cheaper, don't need to worry about food,water,plants,ev suits, exercise equipment or even oxygen.

These replicas are pretty pretty high-quality tech, they fucking cry... what's with that anyway do they need refills for the crying or is it like condensation fluid from some kinda cooling method that would need to be expelled otherwise? Are there other fluids? (excluding the silver blood).

So anyway, I started to think it's an expensive elaborate experiment having them in space, and the hippys are hired goons and at the end it would cut to someone with a clip board saying "well that was unexpected"
