back and landing burns now to initially kick off the raptor engine startup you need some spin-up gas which i believe is still helium or at least for now now this gas is fed through during this startup process to get the turbo pumps running the fuel and oxidizer through the engine because the inner engines will be restarting several times those restart capabilities need to be on board that is why we see the copv tanks on the vehicle which hold the helium throughout the flight and the landing there aren't very many of them though certainly not enough to feed the pressure to all of the outer NUMBER_TOKEN engines as well so here is the thing there is no need to ever restart the rboost engines during flight so including all of this complexity and extra mass just to restart the NUMBER_TOKEN engines would be significant and unnecessary instead we see that there are actually external qd ports on each out engine facing outward as shown beautifully by ryan hansen space we've also seen the renders by the amazing blender NUMBER_TOKENd and space enthusiast which show the detailed mechanisms for the launch table essentially here there are two flip out parts for each of the NUMBER_TOKEN engines the lower part we see here is what the entire booster sits on it sits inside the table with the weight being distributed right around all of these lower holding arms that is fairly straightforward but the upper flap part here flips out and provides the gas feed to connect to each booster engine these spin up gases flow through to the qd ports here on the outside of the engines so given this i think it is safe to therefore assume that this is the only method of spinning them up once the booster launches and the feed lines are disconnected i doubt that the outer circle of raptor boost engines have the capability to restart again in flight so while we are on that topic this past week this qd hood was spotted by starship geyser this piece we believe will go onto the launch mount to cover protect and support the qd mount within which attaches to the booster once again another terrific render of how this system could look with the hood installed interestingly we have just recently seen the first test of that mount with it translating forward and back as it will when it connects and disconnects from the booster heading up the tower crews lifted the starship quick disconnect propellant loading attachment up onto the qd arm for installation quite some alien vibes going on here this was rapidly installed and prepared for testing and it's going to connect to the ship's qd panel after it is stacked onto the booster to provide propellant and power along with stabilization a big thanks today to ryan hansen space for creating such wonderful visuals to show you all and for providing a few exclusive renders here most awesome of you ryan if you are not familiar ryan has produced some of the most realistic and incredible starship renders out there this terrific work is still hugely underrated so please do follow there on twitter it is awesome work likewise as well for oh that continues the epic engineering challenge of putting all of this together the entire team here meticulously looks at all the parts being delivered and finds ways in their NUMBER_TOKENd models to make them fit it is just amazing what they all do so thanks for supporting them and of course for supporting what we do here as well as subscribing liking and sharing it means the world to all of us the launch of the james webb space telescope has been delayed again due to an incident i'll jump into
