I know I said in this post that Andy wouldn't go to space, but like the idea of her in space is so much fun.
Her first time on a spaceship everytime it groans Andy is convinced it'll fall apart and she's terrified. She won't show it naturally, she'll complain about this rickety 'height of human engineering' and how it's worse than the first planes and generally the wors thing humanity ever came up with.
She'll sleep close to the escape pods, cause dying over and over in the frozen void of space is not on her todo list. Also, she will complain about escape pods cause "oh great then I can starve over and over on a god forsaken planet!" but she'll still stick close to them anyway.
Will probably complain about spacesuits being uncomfortable, bulky or something else (or all of them together).
If the artificial gravity fails she will complain until there's no tomorrow but also will greatly enjoy it and just mess around like the little gremlin she is (while complaining).
The first time she doesn't complain is when she gets to see the beauties of space, earth from orbit, nebulas and all that really pretty shit. She gets quiet and there's this awe in her eyes and she realises space is so big she might never get to explore all of it even with her immortal lifetime and so there's suddenly this vastness, this new thing, this hope to her. Something she can't run out of.
She complains less after that happens... until she realises fake space coffee tastes like shit and then she's right back to complaining.
And another thing Andy realises after a long while in space is that she gets homesick for earth. After being there for millenia, knowing every corner, she misses knowing every corner. It gives her a whole new appreciation for everything.
