Planets & Space — The Astral Realm

The space-progression chapter, built on Ad Astra (+ Giselle addon) and tied tightly to tech mods. It’s a long-term parallel goal: build steel and machines, craft rockets tier by tier, and travel from the Moon out to other solar systems. Expect heavy overlap with Tech & Automation Mods — Ad Astra machines run on power from any tech mod. See also Dimensions & Space Travel Mods.

Walkthrough (roughly in order)

  • Materials base — Craft Steel Plates/Rods (used in nearly every recipe), Iron Plates/Rods, and Gas Tanks. Obtain Steel by smelting Iron in a Blast Furnace; compress iron/steel via the Tech Reborn Compressor (overclockable).
  • Power — Start with a Coal Generator. Ad Astra machines accept power from any mod; the chapter recommends Tech Reborn Glass Fiber Cables.
  • Life support — Build an Oxygen Loader to fill Oxygen Tanks/Cans (craft 5 and fill them), and craft a Space Suit (later upgradeable with Jet Propulsion). Make a couple of Fans.
  • Fuel — Find an Oil Well, build a Fuel Refinery, and add a Fuel Loader to load rockets automatically. Later, the Cryo Freezer makes Cryo Fuel (far more efficient — one bucket launches a rocket).
  • Rockets (Nasa Workbench) — All rockets share the same recipe layout; only the material tier changes. Each needs 4 Fins and a Steel Engine (built from Engine Frames).
    • Tier 1 → the Moon / low orbit (Space Stations).
    • Tier 2 → Mars (needs Desh, found only on the Moon).
    • Tier 3 → Mercury and Venus (needs Ostrum).
    • Tier 4 → other solar systems / Glacio (needs Calorite).
  • The Moon — Visit it; kill Star Crawlers and Corrupted Lunarians (pick them off from range), find Cheese, Lunar Towers, Lunarian Villages, and Moon Dungeons. Mine Desh.
  • Mars — Ice Caps (“water on Mars?”), Canyon Creek, Martian Raptors, and the Mars Temple. Mine Ostrum.
  • Mercury & Venus — Venus holds riches; Mercury is mostly uneventful (kill Magma Cubes). Mine Calorite.
  • Glacio (Tier 4 system) — Kill Pygros, Moglers, and Glacian Rams (milk them), collect Ice Shards; visit Pygro Towers/Villages. Unique sun.
  • Space Stations — Buildable in any orbit; bring enough Steel / Ostrum / Desh (amount varies by planet). Water freezes there. A Zip Gun (fill with oxygen) propels you in low-gravity orbit.
  • Infinite oxygen setup — Oxygen Distributor kept running by a Water Pump over an infinite water source, both supplied with power.
  • Shortcut quest — You can also just craft a Waystone (“No rockets needed!”) for return travel, and craft a Flag to plant on the Moon.

Tips

  • This chapter is really a tech chapter — get Steel, power, and the Tech Reborn compressor going before chasing rockets.
  • Each rocket tier is gated by a planet-specific metal: Desh (Moon) → Ostrum (Mars) → Calorite (Venus/Mercury). Plan mining trips accordingly.
  • Cryo Fuel dramatically cuts fuel needs — build the Cryo Freezer once you can.
  • Bring a Waystone to any planet/station so you can hop home without a return launch.

Anticipated questions

  • Do Ad Astra machines need Ad Astra power? No — they run on power from any tech mod; Tech Reborn Glass Fiber Cables are recommended.
  • What gates each rocket tier? Planet-specific metals: Desh (Moon) for Tier 2, Ostrum (Mars) for Tier 3, Calorite for Tier 4.
  • How do I breathe off-world? Space Suit + filled Oxygen Cans/Tanks (via an Oxygen Loader), or an Oxygen Distributor + Water Pump for a permanent base supply.
  • Easiest way home? Craft a Waystone and bring it with you — no return rocket needed.
