How do I create tier 3 science packs in Factorio?
There was a research item to allow you to craft Tier 2 Science Packs, but there doesn't seem to be any research to enable the tier 3 science packs and some of the research items now require them.
Best Answer
Science Pack 3's require a good chunk of research before you hit them. They come from the Battery tech, which itself requires you to research a new resource type: Oil. From there, it just takes Sulfur, and then you can research Battery. You WILL need Plastics, as well, as Plastic Bars are in the resource chain (as part of Advanced Circuits).
Be aware, though, that the amount of resources required for Science Pack 3's are rather heavy, so having the infrastructure in place to make these things is a non-trivial effort.

How do you get science packs in Factorio?
The Space science pack is an end-game science pack. Unlike the other science packs, the space science pack is not directly craftable. Instead, it is obtained by launching a rocket from a rocket silo equipped with a satellite. 1000 space science packs are obtained each time a rocket with a satellite is launched.How many science packs do you need in Factorio?
