There is actually a fair bit of leeway on this - some players might want to have characters remember things things about their own future, due to their on-ship memories (like say, take Marco as an example. Send him back far enough, and he won't be able to morph anymore. But he's morphed on the ship, and thus might remember doing that, and know that he gets that ability in his future).
However, for rule of drama, sometimes you might not want your character to remember that sort of thing. In that case, you can play it as if they only remember Stacy stuff when prompted explicitly, or they remember fully but don't believe it (and think that those memories are false), or, if you really don't want them to access the memories at all, you can say that the disconnect between their canon and on-ship memories is just too far apart for them to process, and so while the memories are there they're just kind of blocked. But generally, that just related to conflicts between canon and in-game memories. For the average on-ship stuff - waking up, the fact that their worlds are gone, their general every doings, etc - they'll remember.
Course, near the end this is probably going to play havoc on their psyche. Because they'll be younger and feel like they're that age, but have all these confusing memories of being older (unless you decide that they'll block those memories).
...okay, in short after all that rambling: the memories are there, but it's up to players to decide whether they want their characters to continue remembering those memories, or block the ones that conflict with their canon memories.
