Factorio Space Age Planet Guide: Recommended Progression Order

Once you leave Nauvis in Space Age, your planet progression order significantly impacts factory growth in the mid to late game. This guide walks beginners through intermediate players through a Vulcanus-first strategy, exploring Fulgora/Gleba branches, and positioning Aquilo as an endgame target. Rather than prescribing one "correct" answer, I'll show you where each path gets easier or more complicated, so you can build factories that actually feel stable rather than constantly bottlenecked.

From my own playthroughs, jumping to Vulcanus first and unlocking smelters and large mining drills changes iron and copper output dramatically. Plate production scales visibly, ore depletion slows, and your resupply convoys don't need constant babysitting. Pairing that with an eye toward interplanetary logistics pitfalls—chiefly destination assignment and landing pad congestion—removes a lot of the guesswork from which planet to tackle next.

How to Think About Planet Progression Order

Planet order is clearer if you frame it around what you want to unlock rather than which planet seems "easiest." Space Age's mid-game balancing act involves both the planets themselves and the logistics load you create after arrival. I break the decision into three angles: purpose, tolerance for the constraints that planet demands, and resupply cost from Nauvis.

If your goal is base production efficiency, Vulcanus pulls ahead strongly. As the community wiki notes, Vulcanus unlocks features that directly harden your manufacturing foundation. Smelters gain +50% base productivity, and large mining drills halve resource cost per ore extracted. The conversion efficiency from iron/copper ore to plates jumps to 2.25×—a striking improvement. Same input, far better output. Your ore fields last longer, convoy shortfalls drop, and your bottlenecks shift from "where's the iron?" to "where do I put the next production line?" That shift in focus is itself a powerful signal that you've chosen right.

Conversely, if your goal is touching unique research or planet-specific mechanics early, the second planet branches. Fulgora shows strong +50% electromagnetic plant productivity in available data, making it appealing for anyone prioritizing power and circuits. That flows cleanly after Vulcanus: harden materials, then sharpen electronics. Vulcanus → Fulgora follows naturally. Gleba works differently. It's not a question of strong versus weak, but of whether your design mindset fits its rules. Spoilage and freshness become structural. Build the same way you did on Nauvis—hoard surplus to stabilize—and it won't feel right. Taking Gleba third lets you build experience and production headroom first, then adapt to its time-based constraints.

A few players report drastic robot efficiency losses on Aquilo (experience reports only; primary source verification pending). If that's your setup, leaning into belts and ground transport becomes necessary. The core point stands: planet order compounds better when you build production surplus before hitting Aquilo's land and thermal constraints.

Roughly sorted, the beginner-friendly baseline is Vulcanus first. After that, Fulgora or Gleba depending on whether you want straightforward expansion or special-case management. Then Aquilo comes last. This order clicks because Vulcanus raises efficiency for all planets, the second planet addresses either stability (Fulgora) or novelty (Gleba), and Aquilo's heavy constraints land after you've built enough cushion to absorb them.

One more often-overlooked element: logistics fineness. Space Age doesn't let you complete factory design within a single planet. What you export from Nauvis, self-supply on-site, and haul back all directly feed production rates. The community wiki's deep dive into destination assignment and pad occupancy clarifies the sticking points. Vulcanus first works partly because its unlocks reduce interplanetary shipping cost across all planets. Thicker plates and intermediate goods mean later planets' setup runs lighter.

Prerequisites: Unlocking Interplanetary Travel and Preparing Nauvis

Research and Route Visibility

Before leaving, clarify when and where you can go. Space Age's research tree includes Discover Planet X studies; completing them adds that region to your space map. On the map itself, navigable routes show as white lines. This visual is crucial for planning. Initially I glossed over it—thought "research done = anywhere possible"—but the space map made everything click. Research trees scatter dependencies in your head; the white lines show at a glance which routes your current factory can actually sustain.

Minimum production stability and defence on Nauvis before departure

Early expeditions often fail not from planetary challenges but from thin support at home. I launch once I have at least iron plates, copper plates, steel, and electronic circuits stockpiling steadily while I'm away. If those lines stall, every missing item forces a Nauvis recovery mission, killing tempo. These four chains underpin nearly every setup item. Ramping up turrets, belts, or power all bottleneck on plate and circuit supply. Vulcanus boosters help later, but the bridge to that point rests on solid Nauvis basics.

Defence works the same way. I push to turrets, ammo, and walls—not obsessive overkill, but enough so biters can't crack the perimeter. Offworld focus means your home base gets neglected; defensive alerts pulling you back repeatedly waste momentum. One complete wall loop, turrets at stress points, stable ammo supply. That alone feels dramatically safer.

Don't skip Nauvis's uranium plan. It's not make-or-break immediately, but mid and late game feel it on both power and weapons sides. Some guides highlight this during Nauvis prep, and rightly so. You won't rush extraction, but having a uranium plot and power/logistics routed before you need it smooths later expansion hard.

Early expedition starter pack

Don't try to self-supply everything on a new planet. Instead, stock your spacecraft with 30–60 minutes of essentials so you can establish a bridgehead fast. You need just enough to power, defend, and kickstart basic production. Your initial spacecraft and platform loadout benefit from the same mindset.

What proved crucial for me: 3 stacks of walls, 10 stacks of ammunition, solar + accumulators, and a turret setup. Land, place perimeter, set up power, build a forward base without panic. Fortifications and power first, then place miners and assemblers. That lets me skip mid to late panic over biters.

Platform prep favors function over cosmetics. Minimum power, cargo transport to offload, and an honest count of what to send planetside. That's three points of value even on the first trip. Interplanetary logistics gets refined later; early runs should focus on self-sustaining the landing zone. If Nauvis churns out plates and circuits steadily, resupply packs and spacecraft runs feel effortless. Weak supply turns each expedition into an event, not a continuous operation. Early prep becomes your launchpad for scaled future runs.

Recommendation: Vulcanus → Fulgora or Gleba → Aquilo

The Complete Picture

Straight answer: Vulcanus first, then Fulgora or Gleba, then Aquilo. I judge this order not by total research count but by how quickly you thicken your factory's backbone. That framing makes Vulcanus a commanding first pick.

Reason is simple: Vulcanus unlocks flow directly into factory fundamentals. Large mining drills extend ore field life. Smelters boost plate and intermediate yields. Combined, as noted earlier, you get 2.25× conversion efficiency. That's not a local convenience but foundational strength for every planet that follows. Your first move's ROI is exceptionally high.

Second picks branch into Fulgora or Gleba. No absolute victor—just different rewards for different play appetites. Want stability? Fulgora's +50% electromagnetic plant productivity compounds smoothly atop Vulcanus strength. Want novelty? Gleba's spoilage system is mechanically rich if you embrace it. Either way, Vulcanus thickening your base beforehand cuts the ramp-up pain sharply.

Aquilo slots into endgame for clear reasons. As the community guide notes, Aquilo carries stacked constraints—land scarcity, thermal hassle, logistics dependency—plus it's the key to unlocking the late-stage gate (I won't spoil further). You want full production and shipping redundancy before tackling that. Front-load power on earlier planets, arrive at Aquilo already strong, and those heavy requirements become manageable rather than crushing.

Branching at the Second Planet

Choosing Fulgora or Gleba isn't about "easier"—it's which rewards and constraints suit your playstyle. I picked Fulgora second in a recent run and noticed module unlocks arriving sooner; research felt visibly stable. Feeding thick plates and intermediates into Fulgora's electrical gains made the whole factory sweep upward cleanly.

Fulgora lands at position two easily because +50% electromagnetic plant productivity is immediately understandable and strong. Harden resource efficiency on Vulcanus, sharpen electrical output on Fulgora, and the flow is architecturally clean. Factory gets stronger, then specialized.

Gleba, conversely, stays swappable for a reason: stronger later, after you've absorbed its philosophy. Gleba's charm lies in unique mechanics, but spoilage and freshness tie expansion tightly to design, not just scale. Increase production blindly and flow breaks. Early runs taught me that base and logistics fineness matter before Gleba arrives. Even knowing its tricks later, adding it at position two splits your head between "do I build more?" and "do I need fresher micro-routing?" Taking it third lets the second planet shore up your tempo, then Gleba's time-pressured planning feels stimulating instead of grinding.

So: For assured growth, pick Fulgora second. For special mechanics and planning puzzles, pick Gleba second. Either way, Vulcanus' resource floor beneath you makes the choice land softer.

Why Aquilo Lands Last

Aquilo anchors the endgame for good reason: its constraints are heavy. Thermal requirements, land layout headaches, and logistics tightness arrive together. You can't pure-resource-pressure past them. Players report robot work feeling sluggish there (reported experience; full mechanics verification awaited), so belt-heavy designs stabilize better. The pressure is structural, not just busywork.

Beyond raw difficulty, Aquilo gates late-stage progression. The rail gun you unlock there isn't cosmetic—it's the ticket through a major late-game gauntlet. Aquilo isn't "tackle it when ready"; it's the ramp-up to the final chapter. Ordering it last pairs demand with your readiest factories. You'll have asteroid yields and steel-per-second planned by then. Facing Aquilo after maxing Vulcanus + Fulgora/Gleba layers your cushion precisely where you need it.

Planet Comparison: Vulcanus, Fulgora, Gleba, Aquilo

Vulcanus: The production-efficiency anchor

Bluntly: Vulcanus first feels straightforward because it's the clearest path to broad factory hardening. I judge planets across five axes: resource payoff, unlocked tech, logistics load, build constraints, and beginner-friendliness. Vulcanus balances all five better than any peer, especially resource and tech angles.

Resource-wise, it directly thickens plates and intermediate supply. Post-return, your entire network—Nauvis included—leans easier. I noticed in comparison runs that Vulcanus-first expeditions let me estimate resupply far more accurately than when skipping it. Choosing what to self-produce and what to ship becomes precise because your baseline improves first.

Unlocked tech is equally clear: furnaces and drills, spreading benefits across the board. No special rule mastery needed. Build constraints exist but don't flip your design philosophy the way Gleba's spoilage or Aquilo's thermal squeeze do.

Logistics load stays manageable. Thickening plates and steel on Vulcanus steadies resupply to later planets, transforming expeditions from "survive scratching ore from nothing" to "unload supplies and ramp up." Downstream planets' difficulty genuinely drops. Vulcanus is strong not in isolation but in making every other planet easier.

Fulgora: Sharpening circuits and modules

Fulgora ranks as a highly viable second pick. Data on my end is less complete than Vulcanus or Aquilo, but the pivot point is clear: electromagnetic plants at +50% base productivity. If you're hungry for circuit and module scaling, Fulgora slots neatly after Vulcanus.

Resource strength leans toward "what do you do with all these plates?" and less toward "where's the ore?" Vulcanus fed commodity bulk; Fulgora ups the value density of that flow. Circuits and modules become less of a choke. My feel playing it is that Vulcanus → Fulgora runs smooth: raw stuff → refined stuff, a natural two-beat.

Tech unlocks target electronics and powering up. Framed as "strengthen your electrical pipeline" rather than "master exotic gimmicks," it lands well for newcomers. Build constraints are real but not philosophy-flipping.

Logistics load sits middle ground. Not Gleba-tier spoilage complexity, not Aquilo-tier environmental squeeze. Hauling supplies in and establishing a foothold feels more routine.

Gleba: The spoilage and freshness puzzle

Gleba splits opinions hard. From a pure-strength angle, it's interesting; from a "second planet" angle, divisive. The reason isn't weakness but how its strength emerges. You can't just build more and stabilize like on Nauvis. Freshness and spoilage become your design axis. Lines short-circuit fast, location matters hugely, and stashed surplus won't save you.

This contradiction makes it harder to love early on. Raw numbers might be good, but you're simultaneously wrestling when to harvest, where to store, how to cut rotting time. Beginners playing Gleba second without Vulcanus-level production breathing room often find management overhead worse than any resource crunch. I felt this acutely on first contact; I built extra production lines convinced I was undersupplied, only to realize the line design itself was fighting spoilage.

Logistics load is deceptive. Even thickly supplied Gleba won't feel fluid if your on-site routing can't keep pace. Bring enough raw stuff and it still bogs down unless the local flow is tight.

That said, Gleba is genuinely fun if you like building puzzle-like systems and time-pressure scheduling. Moving it to third lets you arrive seasoned and appreciative. Alternatively, if you're the type who enjoys spoilage-aware routing from day one, Gleba second is defensible. But statistically it shines brighter after a Vulcanus cushion.

Aquilo: extreme constraints, heavy lockdown

Aquilo is unmistakably endgame. No planet packs as many simultaneous pressures. Cold environment, cramped land, complete logistics dependence. You need pre-existing production surplus or you'll grind.

Resources and research payoff matter—this is where late-game techs branch—but the entry barrier is steep. Robot work reportedly runs sluggish here (player reports; waiting on hard confirmation), pushing belt and ground-transport weighting. Land limits mean you can't sprawl; thermal requirements split your building footprint.

Most crucially: Aquilo gates a major late-stage progression. The unlocks there aren't flavor—they're keys to final chapters. That's not a design weakness; it's positioning. Face Aquilo after Vulcanus' efficiency gains and your second planet's specialization, and those constraints compress into manageability. Tackle it too early, and you're reinventing logistics and base layout on hard mode.

Why Vulcanus First Holds Steady

Large Mining Drills: ore longevity and extraction

Early on, grab the mining drills. they halve resource cost per ore extract. Think of it as doubling effective ore-field lifespan. Mid-game crunch points usually arrive not from "ore type absent" but from "refilled the outposts again, and they're already depleted." Large drills push that boundary back. Convoy downtime drops visibly.

Architecturally, it's elegant. Every ore type benefits—no specialization needed. Factory struggles often trace to "mining bottleneck eroding faster than I reexpand" and large drills directly extend the breathing room. Resupply convoys feel less frantic.

Smelters: +50% productivity and 2.25× conversion

But extraction alone won't smooth the flow. Smelting is the choke point paired with mining. Furnaces gaining +50% base productivity means the ore you do pull converts more efficiently. The 2.25× iron-ore-to-plate conversion figure is where the magic peaks: same ore stream, visibly higher plate stock.

This compounds the drills beautifully. Extract slower but convert harder, and the net effect is a richer plate pipeline. Everything downstream from furnaces—belts, machines, power lines, anything made of plates—suddenly feels less starved. I remember that moment clearly: same input, inventory growing, work pace picking up.

Reduced interplanetary shipping weight

Beyond local gains, Vulcanus shrinks what you need to ship. Refined plates are lighter per unit value than raw ore. Efficiency gains mean you're not scrambling for raw materials as desperately, so your early resupply runs to new planets are leaner. You're not hauling bulk plates endlessly; you're supplementing self-supply on your new foothold.

This shapes second-planet playstyles. Fulgora or Gleba don't demand you haul mountains of ore if Nauvis plate production is already humming at 2.25× normal conversion. Logistics feel solvable instead of crushing.

Vulcanus' staying power comes from this: not a one-time win but foundational strengthening for every subsequent outpost. Once ore-to-plate efficiency and extraction longevity improve, every other planet's startup becomes lighter. Broad-based utility is why it anchors the recommended path.

Picking Gleba or Fulgora Second: Personality Fit

Gleba-second works for some, struggles for others

Choosing Gleba second suits people who treat spoilage-aware routing as a design challenge, not overhead. Farming systems are genuinely interesting if you're the type to enjoy time-pressure puzzles and optimizing freshness windows. Every ingredient's journey matters; surplus can't be a safety blanket. If that fires you up, Gleba second is defensible.

Conversely, folks craving straightforward scaling hit a wall. Gleba rewards clever production design over more production. Research feels slower because your lines fight decay instead of pushing output. Frustration creeps in. I've experienced both angles—sometimes the "solve freshness routing" puzzle is gripping; other times, watching resources spoil despite having "enough" is grinding.

Success on Gleba second hinges on mindset, not skill. No cosmic reason it can't work early. But community patterns show it settling better at position three, after you've built confidence and production fat. That's not weakness; that's specialization requiring a runway.

Fulgora-second is more universally solid

Fulgora second is straightforward: straighten out electronics pipeline, keep the factory humming. The moment where you realize circuit production no longer throttles research is tangible. Engineers tend toward "ensure steady resource flow" and Fulgora plays to that instinct.

You arrive at Fulgora with thick plates, smelt two, slap down electromagnetic plants, and circuits start stacking. No spoilage paranoia, no time-boxing. Textbook progression. Most playthroughs roll this way because it feels right—every planet adds one specific capability, stepping outward.

decision tree

Order ambiguity shrinks if you ask: "Can I enjoy spoilage as design, or does it feel like loss?"

1. Spoilage-as-puzzle: Gleba second is your call. Embrace the freshness routing.
2. Straightforward pipeline growth: Fulgora second. Escalate your circuit capacity and shore up research.
3. Either way, Aquilo waits late. Pre-cushioning is non-negotiable there.

One unshakable truth: Vulcanus first is the safe bet because it doesn't require a second planet pick—it just makes both options easier.

Common Pitfalls: Early Logistics, Pad Congestion, Bottlenecks

Destination assignment quicksand

Interplanetary networks have a trap: each item requires a source planet nomination. Assuming "fluid auto-distribution" like ground logistics often blindsides new players. Specifying which planet sends what becomes mandatory, and adding sources multiplies complexity.

Hardest scenario: one item from two planets serving two destinations. Suddenly you're juggling four mappings, and every new line drags you back to revise. The logistics aren't logistics anymore; they're dispatcher scheduling. I hit this hard early—split control-board supply between two planets and two factories, and the config nightmare swallowed hours. Setup time overshadowed gameplay.

Escape hatch: keep source-destination pairs simple. Steel from X, circuits from Y, fuel from Z. One supply → one demand per item. Configuration stays clean, needs are clear, scaling feels manageable.

Community wiki sections on deep-space network detail the quirks; leaning on those framing as "assign origin, not auto-route" clicks fast.

Cargo landing pad saturation

Another subtle trap: landing pads are finite, not infinite. Small frequent shipments jam early arrivals and block high-priority loads. I once watched fine-detail resupply clog the pads, and critical shipments couldn't land—factory ground to a halt despite "plenty of incoming cargo." Pads filled with junk, bottleneck turned invisible.

Classic mistake: trickling small batches of screws, wiring, belts. Looks helpful, feels safe (constant replenishment), but it burns landing slots for low-value freight while blocking urgent arrivals. Pad saturation is different from undersupply—you have cargo en route, just can't land it.

Fix: big batches, sparse arrivals. Land a week's worth of circuits once a day instead of daily trickles. Pads empty faster, priority jobs slot through. Keep one or two pads reserved for critical inbound (never let all pads fill).

Setting up for stability isn't "deliver constantly" but "land when needed, land big." Cargo ships are tools, not taxis.

Minimum viable logistics

Don't overbuild interplanetary transport early. Maturity comes from restraint. Early-phase networks should handle maybe 3–4 items max, all with clear roles. Dither on what counts as "critical enough to ship" and you're instantly managing logistics instead of building factories.

Structure as: **what does this planet need to self-start?** Not "what does it eventually consume." Nail a few essential routes (power setup, mining, initial defense) and let everything else self-develop. This keeps configurations honest and pad queues short.

One principle: supply source should be as few as possible per item. Multi-sourcing splits brainpower. Stick to 1-to-1 pairs (this planet sources this; that planet sources that). When confidence peaks, branch a second source. Premature redundancy just adds config overhead.

The endgame: Aquilo and the late-stage gate

Aquilo's interlocking constraints

Aquilo is a cumulative-load endgame. Thermal limits, cramped real estate, logistics dependency—none alone would be crushing; combined, they demand setup precision. Robot automation, a Factorio staple, reportedly feels labored there, pushing players toward belt-based flow. The bottleneck isn't "where's the resource" but "where do I physically place this, and how do I heat it?"

This isn't difficulty-ramping flavor. It's a design shift. Earlier planets reward "build more, solve harder"; Aquilo rewards "place smarter, flow tighter." Missing that difference burns time on wrong approaches.

Rail guns and late-stage progression gates

This is where the spoiler-sensitive part lands: Aquilo unlocks equipment crucial to a major late-game gauntlet. Not weapons flavor—functional progression gates. The rail gun and related techs aren't "nice-to-haves"; they're keys.

Structurally, Aquilo isn't a milestone you tick off; it's a ramp-up phase for the final chapter. Treat it as the last fortress before the frontier. Arriving well-supplied, well-practiced, and with existing asteroid production plans hammered out is non-negotiable.

Placing it last isn't avoidance—it's properly sequencing your preparation. By the time you land, late-game unlock will matter; you'll already have the throughput and resilience to sustain it.

The experience milestone

Late-stage arrival carries narrative weight beyond mechanics. Without spoiling, landing at the final frontier feels like a payoff. The confinement and logistical strictness of Aquilo, overcome through skill and planning, land harder because of it. That moment matters.

Which is precisely why rushing into Aquilo under-resourced feels hollow. Arriving after Vulcanus durability and mid-game specialization delivers the emotional beat cleanly. Orderly progression isn't flavor—it's story pacing.

Summary and next steps

If progression order feels murky, anchor on Vulcanus first. Then fork: Fulgora for steady growth, Gleba for special mechanics. Place Aquilo late, with full logistics and production confidence built.

Early success comes from lighter, not heavier, inter-planetary logistics. Broad base, minimal item count, fat batches, spare pad space. That's how planets connect without grinding into bureaucracy.

Nauvis checkout list before departure

• Plates, steel, and circuits self-stacking while you're away
• Perimeter defended, ammo in supply
• Fuel and ammunition loaded aboard your spacecraft
• Power grid and cargo transport staged in your launch platform

First-landing decisions

Pick your target based on which constraints sound manageable. Ship what matters (power, defense, initial production seed), not what's complete. Self-supply on-site where possible.

testing minimum viable logistics

First-run logistics should handle maybe 2–3 items, chosen for criticality. Route configuration tight, pad discipline strict, batch size fat. Afterwards, add new items as confidence grows, not before.

Reference material for platform design and interplanetary detail is in preparation. Check official Factoriopedia (https://wiki.factorio.com/) and Space Age mod pages (mods.factorio.com, GitHub, etc.) for canonical specifications. Prototype small first, then scale once stable runs prove the design.

Your pathway is clear: Vulcanus strengthens you, your second choice diversifies you, Aquilo challenges you, and the endgame frontier awaits. Build steadily, and that final push lands as triumph, not survival.
