Are you looking for more space theme anime that is not a space epic? The Orbital Children and Space Brothers might have completely different stories, but they will keep you engaged in their narratives by showing excitement and tension without including military conflicts. Space Brothers is more grounded in current/near-future realism. The Orbital Children is more futuristic with its inclusion and use of artificial intelligence. Both anime will satisfy your need.
