If you are not interested in playing through the levels, you can access Ship Design, Module Design, and all of the science behind the game immediately and test out your creations in the Sandbox. To do so, go into Infolinks->Concepts->Unlocking Content. There will be a button which allows you to unlock the science of the game immediately, rather than unlocking it by playing through the levels.
The blog goes into depth about the science of the game. [Blog]
There is no official translation, however, if fans are willing to translate the game content, this content can be officially included in the game. A fan has currently translated one of the trailers into Chinese, so a Chinese language patch may be released after the game ships. [Chinese trailer]
