I have plenty of space fairing aliens with wings that are capable of flight. I can’t help myself it’s just a cool feature for an alien and a have. But I want to adress A potential issue in getting a species literally born to fly past the atmosphere.
See, in the same way that standing on a thrust-grav ship hitting 1 G it feels exactly the same as standing on earth, free falling feels the same as zero gravity. Now since humans were designed to walk on the ground, when a human experiences Zero G, it’s fun, it’s something you talk about with everyone back home. However a winged creature is hard wired to maintain control while airborne, so they will not react well to free falling. Their instincts tell them, “you are falling to your death, correct yourself before you splatter into the ground.” Following that same instinct, they will attempt to correct themselves which works in a gravity well, but not in zero g. They will flail, they will have less control of themselves which would gradually lead to even greater panicking, and a panicking astronaut is not a good thing to have locked inside your spaceship.
Now there was an example of this in an MLP fanfic where the winged member of the party experienced such a panic.
(You can watch it here, https://m.youtube.com/watch?v=4XXm1PZfcBo&list=PLY8fTIAEbE4IB8V8NoK9DQ0Q2HJCkQJ-9&index=10 I know that the video was long the relevant part starts at 30:19-35:27)
Now this was only a single member with wings that was a talented flyer. But what if that was a winged species version of an Apollo mission and there wasn’t a ground pounder to try and calm things down?
But once you find a way past that their are endless opportunities for a flying creature amount the stars. Just ask the birds of Ceres.
So, now for the big million credit question. How would you keep a member of a flying sentient species from panicking when they experience Zero G?
