I went thru all the populated planets, none has TS, which is essential for the production of HE3. HE3 is also essential for the production of FTL fuel. If this is correct, FTL fuel production is currently impossible before the colonized of a planet that has TS. Am I missing something?
HE3 is a natural resource too;
KI-448b and EY-430d are the currently the only accessible sources, until PP3s start getting built.
Just noticed we can also buy from NPCs. Guess it’s not really worthwhile dealing with those remote HE3 systems 
Ha! You should tell Rexhen that who’s set up base on KI-448b!
FF we can buy. HE3 we dont
