Is there some site where i could find the mass estimates for all system components, as well as injection trajectory/delta-V budgets?

All GLXP entrants i heard of seem to have planned to make do with exceptionally low LEO insertion mass. Which sometimes made me think of them as vaporware.

Other than that it's GTO, we didn't publish orbital parameters or spacecraft/payload specs AFAIK.
