Stole a lot of codes from Only-nauvis : https://mods.factorio.com/mod/only-nauvis/discussion

Mod summary

This mod removes all planets and even space platform(thus space science), and make their resources be craftable from nauvis resources. You could call it space age at home, the Factorio 2.0 not space age.

Key changes

• Any research that required space science before, now requires double the science (besides infinite researches), to compensate for much easier logistics and lack of space science.
• All of the quest based unlocks are now purely science unlocks (except for nauvis ones)
• Gleba are available at Green Science level (after oil processing / sulfur processing)
• Most of, if not all, previously planet specific materials can now be made on Chemical plant. it starts a little expensive, but it gets cheaper with certain research.
• Gleba plants require ammoniacal solution to process, which can be directly converted from crude oil after you research biochamber.
• Bio(....)s need their respective research. For example, plastic research is needed to create bioplastic.
• Foundry, Electromagnetic plant and big mining drills are available at Blue Science level (due to their ingredient, lubricant, electric engine and blue circuit).
• Promethium science now requires x1 biter egg, x1 quantum processor, and x4 of rocket fuel/Low density strucuture/Processing units. This is to mimic the rocket launching behavior, and to significantly increase quantum processor cost (by x10).

Note

I expect a lot of mod conflicts, especially if the mod changes recipe/research by any means. This mod is currently expected to be played only as a standalone mod. If this mod, by any chance, gains any popularity I'll start addressing issues.
