I have high hopes for Kliper. It seems to become more and more of a real project. With the R-7 having already been all but perfected (not including the recent Molniya upper-stage malfunctiohn), Kliper just needs a hydrogen upper stage to fit atop R-7.

Kliper could be launched as is atop a Zenit--but that is a Ukrainian LV and the Russians won't have it--or so it seems.
