If the relaxing and replayable rhythm of 星际工业国:崛起 stuck with you, this helps. You will find a few strong contenders among these games.
A space idler that flattens the factory genre into simple conveyor belts: click minerals, smelters and power plants into place, then grow from one production line to an interstellar empire. Recruit commanders, research 158 technologies, assemble warships and conquer planets for land and resources. Easy to start, deep enough to lose weeks to.
Relaxing, Replayable
Build an industrial base among the stars. Gather resources, manufacture ships, research technologies, and explore unknown regions of space. The core gameplay can be played offline, while alliance features add online missions and cooperative construction.

Dyson Sphere Program is a sci-fi factory sandbox where you turn one small workshop into a galaxy-wide industrial empire. Methodical, huge in scale, and easy to lose a night to.

Astro Colony is a relaxed automation game in an endless procedurally generated universe. Build conveyor networks, move and dock your stations, recruit astronauts and research new tech, alone or with friends. No timers, no punishing failure: just you, a growing colony and a galaxy of voxel planets to strip for parts.

Outworld Station is a space factory game without the spaghetti. Link station modules with tubes that carry anything, set up supply chains across planets, and build a fleet of starships in a calm, low-pressure system that fights back just enough. A friendly way into automation, and a fresh twist for factory veterans.
Relaxing, Replayable
Mine asteroids, build production lines, keep your crew fed and trade with passing ships to buy back your freedom. A cartoony colony and automation sim where every run plays out differently.

Star Birds is a relaxed factory game on asteroids. Scan rocks, mine ice and stranger things, and link it all with hand-drawn pipes while your cheerful crew of birds asks for increasingly odd deliveries. Cozy on the surface, a genuine spatial puzzle underneath, with a colorful galaxy of mysteries to uncover.
Relaxing, Replayable
Mindustry mixes factory building with tower defense and real-time strategy. You mine, move and refine resources, feed ammo to turrets, hold your core against waves, then build armies and take enemy bases. It is worth playing for that loop of tinkering, defending and expanding.
