Instellar Extended left some blank tech trees

[ddalcanto]

So, I just got Interstellar Extended and it added some tech tress that are left blank because i don't have the mod they come from. Two of the tech trees seem really cool based off of the title, so I'm hoping somebody can let me know what they're from.

Edit: It seems people are misunderstanding my question. I know that those empty nodes are there because the spaces are reserved by Interstellar, but don't have anything in them because I don't have the mods that use them. That much i could find on google. What I'm asking, it what mods includes the nodes that i took pictures of. They seem cool, so I'm interested to actually add the into the game.

Edit 2: Thanks, i got my answer. It is community tech tree that ads those in

I've had this issue too! I don't know what is in these things and because they seemed empty I didn't spend my (valuable) science points. I hope you can find what's wrong.

The tech tree is most likely changed by Community Tech Tree, which adds nodes for a variety of mods like KSPI and USI. 

If you don't like having the empty nodes, you can either get the USI mod, or get the hide empty tech node mod.

In addition to the good answer you got, those specific tech tree nodes are primarily for USI life support and MKS.
