I'm going to be the realistic replier here...
First off, this forum is for the FTB/Curse launcher, and many of us, like myself, have no experience with the Technic Launcher.
Secondly, this thread is for the Flux Galaxy mod pack, and I'm quite certain neither the Flux Galaxy mod pack creator, nor almost anyone that would read this thread, has any insights into the Nova Galaxy mod pack.
Your best bet would be to contact the creator of Nova Galaxy and ask him to submit it to the Curse/FTB launcher, if you want it to be available on Curse.
Actually considering @ChatFawkes Flux site links to Nova and vice versa+the sites are identical layouts and copyright to him, I would say it is one of his packs that is currently in the works and that it is also listing him as the creator on the technic site it IS one of his packs.
@bugmenot Only ChatFawkes can answer IF or when its coming out on FTB/Curse
