It will be interesting to see the old N-1 NK-33 engines in action.

I'm rather more curious about the PWR35M engine to be flown on
an upgraded version. Apparently a modified RL10 running on
methane; PW has run tests with methane before but this would be
the first actual flight application. Why methane instead of
hydrogen? Lower Isp, still cryogenic, possible sooting issues?
Not even sure if its a turbopump or pressure fed design; no
real details available on PWR's site.

It will be cool to see the NK-33/AJ-26 finally flying again.
Accounts vary as to what versions of this engine actually
flew on the N-1; apparently the original design was almost
completely redone in the course of the N-1's travails.
This time I hope it vindicates the original designers, but
given its past history with N-1 and the never-flown Kistler
K-1 it's not hard to imagine a curse having been laid on the
thing, eh?

(Rocket geekery: there's a duct going down the side of the NK-33's
exhaust nozzle that looks all the world like a turbopump
exhaust, but this is a closed-cycle staged combustion design.
It doesn't appear to manifold into the nozzle, and some pictures
seem to indicate the duct has no opening.)
