Its mission is to send the Starship into a quarter of the earth orbit, which will undoubtedly be the largest rocket booster ever built. The super heavy rocket booster is equipped with up to 28 Raptor engines, which can generate more than 7300 tons of thrust when taking off. The super heavy rocket will also be the most powerful rocket in history. Its thrust is twice that of Saturn 5 rocket and more than three times that of SpaceX's own Falcon heavy rocket. < / P > < p > although SpaceX may take some time to get ready to venture into installing more than 20 Raptor engines on the booster, the super heavy rocket booster will be able to take advantage of the company's extensive experience in manufacturing and testing starship prototypes over the course of a year. < / P > < p > as discussed earlier, although SpaceX has clearly focused on the production of starship prototypes and the high altitude testing of SN8, in the past few months, the company has been gradually pushing forward the first super heavy rocket booster. Recently, the first 8-raptor engine structure, a custom universal tank dome, and an ultra wide transfer tube for delivering liquid methane to a super heavy rocket tank were discovered at SpaceX's bocacchica, Texas plant. The aerial photo on December 22 also shows that SpaceX seems to be working in an 80 meter high bay, stacking two components belonging to the prototype bn1 of the super heavy rocket booster. Although it is impossible to know exactly how SpaceX is assembling bn1, at least 12 barrels are in the stacking stage, and more barrels are waiting to be added to the main booster's "stack". < / P > < p > it is speculated that SpaceX may have all 38 steel barrels needed to complete the assembly of the super heavy rocket booster prototype bn1. As the front dome of bn1 has entered the stacking process of Gaowan, the only major components missing are the engine part and landing bracket of the first prototype of super heavy rocket booster. It's not clear whether bn1 will install the fin bracket previously released by the company, so making engine components is all that's left. < / P > < p > in order to complete Musk's short-range "jump" test powered by only two Raptor engines, the first prototype is likely to be more like an incomplete rocket for "jump" test than something that can put a 2000 ton starship into orbit. SpaceX may even build another test tank to independently pressure test the new engine components of the super heavy rocket and the "thrust disc" structure composed of eight Raptor engines, and then risk assembling about 36 steel cylinders. < / P > < p > in any case, if SpaceX is really ready for the first "jump" test of the super heavy rocket "in a few months", the next bn1 assembly will accelerate significantly.
