    Nope, that’s why I updated my post.

    Most abort systems detach the capsule and quickly remove it from the danger zone of exploding engines, fuel tanks or SRBs (unless it’s a Space Shuttle, no such luxury there). With Starship there’s no way to get out if something catastrophic happens to second stage engines or tanks. (I’m not paranoid, it’s probably not important if Starship indeed reaches the airliner-level reliability)

    Even if Raptors can be used as LES, it won’t help if Starship itself blows up.

    For some reason I thought that RD-107 and 108 were made in Samara.

    “We will create another rocket, the Soyuz-6 medium-class rocket, which will fly on the basis of the RD-180 engine,” he said. “This is a way out of the situation when the Americans stop buying this engine for their needs, so that we will not lose a unique vehicle, a unique motor" He wants to drown Energomash in engine orders. RD-171MV for Soyuz-5, RD-180 for Soyuz-6 and RD-191 for Angara.

    The only reason your rocket flipped out is because Vostok-style soviet capsules are incredibly draggy. It has to be this way in order for them to slow down quickly enough in the atmosphere. Solution: put the capsule inside a fairing.

    Starship Dorian?
  10. sh1pman
    Yeah, and every time there’s a debate about how dangerous electric cars are, and whether the autopilot is to blame.

    So, the best guess right now would be that they: 1) somehow dropped a Burevestnik missile into the sea, likely during the tests; 2) tried to recover it; 3) at some point its nuclear ramjet exploded, killing and wounding several engineers and releasing some amount of radioactive isotopes into the environment.

    Am I the only one here who can simultaneously set up colonies with life support and supply chains throughout the Kerbol system, spend DAYS optimizing SSTO drag and ascent profile for maximum fuel efficiency, and at the same time thoroughly enjoy lolsplosions and rapid unplanned disassembly?..

    A lot less than with kerosene, that’s for sure. Still, it’s an incomplete oxidation with great excess of methane at ~500 bar pressure, so even my chemistry degree can’t help me predict how many intermediate products would be there. It’s probably mostly CO and a small amount of other stuff.
  14. sh1pman
    Side note: CO2 and H2O will only form in the LOX preburner. I’m fairly certain that in the fuel preburner there’s a slew of partially oxidized products like CO, decomposing and/or ionized methanol, formaledhyde, formic acid, hydrogen, acetylene, various free radicals and polymerization products, even carbon and higher hydrocarbons.

    Raptor engine has 3 igniters, one for each preburner and one for the main combustion chamber. Every igniter is also double-redundant. I’m not sure about the order, but it makes sense to first ignite the preburners, and then the combustion chamber.

    Or anyone else. Europe, China, etc. Thing is, if the military makes a working NTR, they won’t be too keen on sharing the design with the rest of the world. Everything about the project will stay classified for the next 50 years, and the only way for anyone else to get the design is through foreign spies. If someone wants to use an NTR engine on their orbital rocket, they’ll have to develop it themselves.

    Parachute issues?

    But it applies to every sci-fi setting ever created. We don’t know if these things work or not, because we don’t have them yet. If we had, it it wouldn’t be sci-fi. Devs can’t see the future, so if there’s going to be any kind of future tech in KSP2, there will be a lot of guessing and assumptions involved. And I’d like it to have some future tech, that’s why I’m fine with metallic H2 engine. It’s clearly more realistic than, say, Mystery Goo, and I’ve never seen anyone having problems with that substance being in KSP.

    I thought the explosion happened “during the test of liquid fueled propulsion system”.

    I don’t think it’s going to be an issue for SpaceX. A large part of launch market is governed by politics, not competition, e.g. organizations getting government contracts because they’re located in the right district, not because they offer the best product. Won’t be a problem for such organizations if SpaceX gets too big and powerful.

    NTRaptor!
  23. sh1pman
    18 meters!? That’s almost as wide as a Sea Dragon... ~150 Raptors on the first stage.
  24. sh1pman
    I hope they got enough science from these four Mystery Goo canisters to unlock all of Starship parts. Otherwise they’re going to need another hop.
