The black tanks on the outside. think they are 80 bar but might be higher. That is the pressurization system who currently keeps tanks at 6 bar and feed the cold gas trusters and will feed the gas-gas engines. The gas-gas engines will be a bit like the raptors starters who also is gas-gas. Probably use multiple spark plugs to ensure smooth starts. Guess they use an gas generator and perhaps electrical pumps to create pressurized gas in case they run low on it say during docking and then they need to pressurize the large tanks, that one however don't need high pressure.

That's what I was afraid of. If you say everything should be ok on your side, then it must be a side-effect from Realism Overhaul. I don't know yet how the differents mods interact, but it seems the RO mod prevent some of your parts to be scalable. I'm going to search. Thanks

Camera tools not working why?

If you’re referring to this: Then it isn’t explicitly marked as compatible with KSP 1.10(.x) so that might be the problem. Are you getting any errors in the logs, and have you downloaded all the dependencies?

What is something you have always wanted to do in KSP but have as of yet to do?

Ever since I first installed the game in 2014, I've wanted to do a Duna mission in science or career mode. I always restarted before doing it, but this install seems to be keeping my attention a lot longer. I've already done a landing on Asclepius (a modded planet between Kerbin and Duna's orbits), and flybys of Eve and Duna. All I have left to do is refuel the interplanetary vessel and attach a lander, but that will still be a week or two of work.

Getting NullReferenceException at CometVFXController.LateUpdate

Having a problem with my career game. For some reason, apparently when a comet spawns, something is wrong because I get the following errors repeated endlessly: NullReferenceException: Object reference not set to an instance of an object at CometVFXController.LateUpdate () [0x00156] in <c1858a3f77504bd1aaa946fdccf84670>:0 UnityEngine.DebugLogHandler:Internal_LogException(Exception, Object) UnityEngine.DebugLogHandler:LogException(Exception, Object) ModuleManager.UnityLogHandle.InterceptLogHandler:LogException(Exception, Object) UnityEngine.Logger:LogException(Exception, Object) UnityEngine.Debug:CallOverridenDebugHandler(Exception, Object) I can fix it temporarily by going into the save file and deleting the comet: VESSEL { pid = 54f8d0d629f941c88626240aa5329f4d persistentId = 3893921262 name = UnknownComet type = SpaceObject sit = ORBITING landed = False skipGroundPositioning = False vesselSpawning = True launchedFrom = landedAt = displaylandedAt = splashed = False met = 6225711.4006192945 lct = 6225711.4006192945 lastUT = -1 distanceTraveled = 0 root = 0 lat = 9.6270188652078712 lon = -86.927851974552311 alt = 28145353356.800259 hgt = -1 nrm = 0,1,0 rot = 0.0685398951,-0.800244808,-0.243902251,0.543527603 CoM = 0,0,0 stg = 0 prst = False ref = 0 ctrl = False PQSMin = 0 PQSMax = 0 GroupOverride = 0 OverrideDefault = False,False,False,False OverrideActionControl = 0,0,0,0 OverrideAxisControl = 0,0,0,0 OverrideGroupNames = ,,, altDispState = DEFAULT ORBIT { SMA = 630842177619.66125 ECC = 0.97469954410955661 INC = -9.688934326171875 LPE = 0 LAN = 144.62237548828125 MNA = -0.0064265099161463779 EPH = 6225711.4006192945 REF = 0 } PART { name = PotatoComet cid = 0 uid = 1738383386 mid = 1738383386 persistentId = 2014826312 launchID = 0 parent = 0 position = 0,0,0 rotation = 0,0,0,1 mirror = 1,1,1 symMethod = Radial istg = 0 resPri = 0 dstg = 0 sqor = 0 sepI = 0 sidx = 0 attm = 0 sameVesselCollision = False srfN = None, -1 mass = 150 shielded = False temp = -1 tempExt = 0 tempExtUnexp = 0 staticPressureAtm = 0 expt = 1 state = 0 attached = True autostrutMode = Off rigidAttachment = False flag = rTrf = modCost = 0 } ACTIONGROUPS { } DISCOVERY { state = 1 lastObservedTime = 6225711.4006192945 lifetime = 1147356.4636230469 refTime = 1728000 size = 6 } FLIGHTPLAN { } CTRLSTATE { } VESSELMODULES { ModularFlightIntegrator { } AxisGroupsModule { } PWBVesselModule { resource1 = resource2 = resource3 = } SnackConsumption { LastUpdateTime = 0 supplierMinerCraftId = lastMinerToDepositCraftId = } CrewRequirementVesselModule { } PksUpgradeVesselModule { lastTimeCheck = 0 } ParkingBrake { lat = 0 lon = 0 alt = 0 positionSet = False } VesselModuleSave { } KSPWheelVesselDebug { } KSPWheelDustCamera { } WorkshopManager { Workshops { } } BetterBurnTimeData { } ModuleStabilization { } CometVessel { typeName = long cometPartId = 2014826312 vfxStartDistance = 2.2105851501226423 comaWidthRatio = 1145895.1771259308 tailMaxWidthRatio = 1 tailMaxLengthRatio = 104.03748750686646 ionTailMaxWidthRatio = 0.29999999999999999 comaWidth = 2229044.1421592887 tailWidth = 2229044.1421592887 tailLength = 231904152.09215087 ionTailWidth = 668713.24264778662 hasName = False radius = 74.5837173 seed = 1738383386 numGeysers = 50 numNearDustEmitters = 125 optimizedCollider = False fragmentDynamicPressureModifier = 0 } KSPWheelVesselControl { } AlertMonitors_Module { initted = True } } } Here is the log file and the persistent.sfs file.

the airbus concepts use cryofuel, storing it in the fuselage. the coldness of the fuel can also be use in a precooler if you wanted a hypersonic aircraft or as the cold side of any thermodynamic components, its effectively another form of energy storage.
