And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

A Soyuz rocket takes off in 2023, carrying three of the Expedition 70 crew to the International Space Station. Now superseded by SpaceX.
LOX and Kerosine. RD40 engines, super reliable, great performance, the American's used them on Atlas and Centaur, couple other boosters, till the idiotic Russian sanctions. They only got a couple sets left. Russian rocket tech is top shelf and when the legacy aerospace corps began using them, not much out there but LOX H2 engines performed better. Elon tried to buy whole boosters from the Russians, they laughed and strung him around for a week. But Elon turned around and developed the Merlin's, as good even better than some of the RD 40 family.
What do you suppose they use for fuel?
