Reusable Rocket


Reusable methane rocket silos for Factorio 2.1 Space Age. Pipe rocket-grade methane into the silo, launch, and recover the rocket by cargo pod. Includes a 9x9 single-rocket silo, a 15x15 heavy silo with Muluna, three methane routes (coal / wood / nutrients), per-planet fuel scaling, and scrapping/refurbishment. Recommended with Muluna. 为《异星工厂》2.1 太空时代加入可回收甲烷火箭发射井:管道灌注火箭级甲烷,发射后由空投舱回收火箭。包含 9x9 单发井、Muluna 15x15 重型井、煤气化/木材气化/营养剂三条甲烷产线、逐星球燃料缩放,以及翻新与报废拆解。推荐搭配 Muluna。

Changelog

Version: 1.0.0
Date: 2026-11-09
  Release:
    - Removed the experimental AdvancedRocketSilos compatibility entirely.
    - Muluna is now listed as a recommended companion mod.
    - Rocket-methane icon: the rocket layer is smaller and moved to the
      bottom-right, leaving the liquid icon itself unobstructed.
    - Scrapped refurbishment no longer shows a "refurbishment failed" text.
    - Added a generated cover image and a bilingual (English / Chinese)
      mod description.
Version: 0.3.0
Date: 2026-11-09
  Features:
    - AdvancedRocketSilos compatibility: a reusable Advanced Rocket Silo using
      the ARS 40 advanced-rocket-part chain. One reusable advanced rocket, 3x
      lift, one craft producing 40 advanced-rocket-construction, returns one
      used advanced rocket.
    - Cerys cryogenic compression is now a 10x batch: 1670 Cerys methane ->
      10 rocket-grade methane in the same 5 seconds (still 167:1 heat-equal).
  Notes:
    - Interplanetary Rocket Silo compatibility is not included yet.
Version: 0.2.1
Date: 2026-11-09
  Changes:
    - Rocket-grade methane is now 835 kJ/unit; 6,000 units = 5,010 MJ.
    - Nutrient methane recipe now outputs 110 methane (same heat input as
      40 wood), matching the wood/coal routes.
    - Refurbishment recipe now lists 90% reusable rocket + 10% scrapped rocket;
      a script corrects the independent rolls (both -> keep rocket, neither ->
      insert scrapped) and never spills scrap on the ground.
    - Renamed display names: reusable rocket, used reusable rocket, scrapped
      reusable rocket. Internal IDs unchanged for save compatibility.
    - New rocket-methane icon combining the petroleum-gas icon and rocket-part.
    - Planet refuel recipes are hidden from the character crafting menu.
Version: 0.2.0
Date: 2026-11-09
  Features:
    - Rocket-grade methane: 833 kJ/unit, 6,000 units = 5,000 MJ on Nauvis.
    - Three methane routes, each gated by its own technology:
      coal gasification (coal-liquefaction), wood gasification (K2 advanced
      chemistry, or oil-processing without K2), nutrient route (bioflux).
    - All methane routes require oxygen only when K2 or Muluna is loaded.
    - Cerys methane stays at 5 kJ; a 167:1 cryogenic-plant conversion produces
      rocket-grade methane at equal heat value.
    - Rebalanced methane production to be slightly heat-positive (+10~11%).
    - Silo fluid buffers are 1.2x the highest recipe (3x + 20% for the heavy silo).
    - Heavy silo returns all three boosters in one cargo pod.

  Fixes:
    - Added locale keys for both silo items/entities.
    - Replaced the custom surface property with gravity + pressure conditions.
    - Refurbishment tooltip shows only the ready booster; scrap is scripted.
    - Replaced the removed flying-text entity with rendering.draw_text.
    - Split the silo into 1T (9x9) and 5T (15x15 Muluna) variants.
    - Fuel ports are now on the south side, third tile in from each edge.
    - Heavy silo completes with one craft consuming 3 boosters.
Version: 0.1.1
Date: 2026-11-09
  Fixes:
    - Added locale keys for both silo items/entities (fixes item-name unknown key).
    - Replaced the custom surface property with gravity + pressure conditions,
      fixing the surface-property unknown-key text in recipe tooltips.
    - Refurbishment tooltip now shows only the ready booster; the scrap roll is
      done in script, so it is exactly the configured chance.
    - Fixed the launch crash caused by the removed flying-text entity; now uses
      rendering.draw_text.
    - Split the silo into 1T (9x9, base art) and 5T (15x15, Muluna art) variants.
    - Moved both fuel ports to the south side, third tile in from each edge.
    - Fluid box volume is now 2x the highest single-booster recipe for the 1T
      silo, and 3x + 20% for the 5T silo, instead of a flat 250k.
    - The 5T silo now completes with one craft consuming 3 boosters and producing
      3 rocket parts, instead of requiring three crafts.
Version: 0.1.0
Date: 2026-11-09
  Features:
    - Reusable methane rocket silo with a direct methane pipe connection.
    - Per-planet refuel recipes using a custom surface property (exact planet matching).
    - Ready / used / scrapped booster items, refurbishment with configurable scrap chance.
    - Scrapped boosters can be dismantled back into low density structures and processing units.
    - Methane from wood (vanilla), K2 oxygen variant, and Gleba bioflux recipe.
    - Booster return by cargo pod to the planet's cargo landing pad.
    - Optional Muluna big silo prototype for the whole reusable silo.
    - Startup settings for fuel exponent, scrap chance and return delay.
  Notes:
    - The rocket silo prototype exposes only one fluid box at runtime, so v0.1
      injects methane only. K2 oxygen canisters are planned for 0.2.
