I'm talking about the distance from the sun and the plants, especially the further away you go.
Photosynthesis happens because the plants adapted to the relative distance between them and the sun. But the further away you go, the less ability to convert energy to food for the plants it becomes.
I'm not talking about atmosphere in that sense. I'm talking about the distance aspect.

»if you have more people, the ship needs to be even more massive to support their food purely from the plants on board and it doesn't become practical
these are married and expert astronauts with years of training on isolation and healthy mental health away from earth etc, humans can easily overcome that kind of thing. there would be space suits to do repairs externally as needed so they would go for space walks regularly.
In theory. But in practice, unless you spend
decades in isolation or analyzing a couple in isolation, you will never know what the long-term effects would be towards them. Even then, sending a group is not practical for the
exact same reason. You may think that people can adapt, but if that's the case, then why do we have insanity?
