  • Once again, Soviet boosters did not have segments and O-rings because they were not solid fuel rockets, the O-ring fault that caused the Challenger explosion could not have happened on the Energia. Period.

    I’m not saying the O-ring fault could have happened on the actual Energia, I’m saying a failure due to mixture of OX/liquid propellant on the actual Energia outside of the ignition chamber could have occurred. I don’t even know if the Energia in the alt history show is liquid fueled. Apparently the STS expys are nuclear powered.

    Once again, not having seen the specific episode in question, I don’t know if they blamed it on o-rings on a liquid fueled rocket erroneously, and even if they had, I can’t fault someone without an engineering, or at least scientific background for making that mistake in the process of making their hackish television show.

    I’ve got no arguments about the superiority of Soviet space tech; when my parents were telling me about For All Mankind where it’s an alt-history where the soviets won the space race, I straight up said to them the Soviets did actually win the space race. I guess I’m just pushing back on this implication that I read into your comment that the transfers of American disasters to the Soviets is some ideologically motivated dig at the Soviet space program. Which is why I brought up their willingness to transfer Soviet disasters to the Americans. It just seems like went the easy route of flipping things on their head for narrative convenience. Hence the Soviet moon landing.


  • We’re talking about Buran not Soyuz. I’m not an engineer and I haven’t poured through the technical documents, but if you’re going to say Buran was in fact immune to the failure pathway that challenger experienced you’ve got to go beyond saying “liquid propellant engines can be shut off” and actually show that the mechanisms for an automated shutoff were in place and would have been triggered before catastrophic failure was inevitable. Some of Challengers main engines shut off automatically, but that wouldn’t have solved the problem and would likely have been too late even if it did address the issue. Would Burans systems save it if there were an external fuel/ox reaction outside of where it was supposed to be? I have no idea. Maybe.

    That’s the sort of inside baseball that I’m not going to fault writers for engaging in, for all the other faults I’ve got with that show.


  • Looking at the challenger flight timeline there was less than a second between verbal indication that something seemed wrong and the catastrophic failure of the orbiter and loss of downlink. Not a lot of time to realize what’s wrong and shut the engines down.

    I agree the Buran would be better positioned to respond to a similar type challenger fuel leakage problem, but I think saying loss of the crew and orbiter from a OX/fuel leakage is impossible is overstating the case.
