That should be a title for a film. I hadn’t really noticed before until rewatching Soldier the other day, but Kurt Russell being a space dad is a trope in itself.
Obviously it reached its apotheosis in Guardians of the Galaxy Volume 2 in which Russell is Ego the Living Planet and dad to Starlord.
But he also gets to be a surrogate dad at the end of Soldier, after Sean Pertwee gets his leg blown off by Jason Issacs’s supersoldiers on a training mission.
He’s also a superhero dad in Sky High:
And involuntarily adopts a set of urchins in Stargate:
So that’s at least four examples and I think three is enough for something to be a thing*.
*[He’s not a space dad in The Thing though]
