Cryptex

Cryptex can be found in crashed satellite. You have 3 chances to decrypt. To decrypt, you need a computer desk. Decrypting these will give you science points, so even if you know some or all of the blueprints they are potentially worth decrypting again. You must activate the decrupted Cryptex - in your inventory or a container - in order to learn the blueprint; simply decrypting it is not enough.
