  1. Loading propellants? Wow. Even if it’s just liquid nitrogen…I’m surprised the quick disconnect plumbing is still in working order, considering the way it was belching flame like crazy as the booster was landing (and for several minutes afterward). I guess maybe it’s supposed to flame like an angry dragon despite that looking like an undesirable anomaly.
  2. In replays I can see where the part of the chine is breaking apart during booster landing burn…so that damage wasn't from hitting the tower.
  3. How long are the Raptors supposed to keep smoking?
  4. The diagram posted earlier in this discussion shows the LOX tank in blue and the Methane tank in red. The volume of the V1 LOX tank appears to be about 7 rings (counting the space of the bottom dome and the space around the upper common dome as one ring), while the Methane tank is less than 5 rings (three full rings and two dome rings). The V2 diagram shows the larger LOX tank increased by one ring, and the smaller Methane tank increased by two rings? Are these accurate diagrams? I don't know. I also Googled "Starship tank volumes" and found a diagram where somebody calculated Starship tank volumes and got LOX tank volume of 793.48 m^3 and Methane tank volume of 604.93 m^3 (with header tank volumes of 14.65 m^3 for LOX and 13.14 m^3 for Methane...not counting amounts in downcomers). Are these accurate? I don't know, but the ratios look to be about correct from the diagrams.
  5. Is that correct? The LOX tank of V1 Starship is larger in volume than the Methane tank.
  6. Why increase LOX tank by one ring and Methane tank by two rings?
  7. @Ultimate Steve My mission report site is just something I made with basic HTML and posted on whatever server I had access to at the time, posting mission reports in parallel with posting them on the KSP Forums. The content has been moved to a couple different servers over the years and is currently on my brotoro.com/ksp website. I'll be sad if the KSP Forums disappear, since not everything I posted is on my site (only the mission reports). I haven't been playing KSP for several years now, but I still hang out in the Science & Spaceflight forum here. In case the Forums do vanish, I would just like to say that it has been a pleasure posting with all you fine people. Per aspera ad astra!
  8. I don't think you can count on having hot gas in the cryogenic propellant tanks to maintain pressurization for long, since the gas will cool in contact with the liquid. You need to generate enough gas that there will still be sufficient pressure in the tanks after the gas cools and the tank approaches equilibrium… otherwise you won't have sufficient tank pressure when you need to restart your engines.
  9. I know. That's why you run the hot turbopump exhaust into this smaller tank of LOX and let the condensation and freezing of the water and carbon dioxide happen in this secondary tank (not in the main tank) Then let the gaseous oxygen out to the main tank pressurization line.
  10. Because you can't replenish Helium on Mars. And a Helium tank has to be under high pressure, so would be heavy. You trap the the ice in this tank using filters (in this case you are filtering gas from the solids and LOX, which I think would be easier).
