new crew members

hi,
am wondering what peoples experience has been being able to acquire new additional crew members.
I was exited about that potential, but so far I have almost finished the first start system and have not seen any opportunities.
is it more of mid/late game thing? or totally random?

let us know how/when you got someone new.
thanks!

I'm not sure if it was in the first star system or the second, but I found a fifth crew member in a stasis pod in my first (serious) play through. I haven't yet found a sixth, and I'm... not sure what system I'm in, fifth or sixth, I think? I think it's RNG, and it's a low probability.
