A new feature is the super-heavy booster gained and how powerful is the new reusable booster. Elon Musk is not the first person to attempt to build a Rocket, however, he is the first person to try to build a space-grade rocket that can be completely reused many times his vision is to reduce. The explorers and the tons of supplies they need from the earth to the planet will be done by which is nearly double the size of the whole rocket it can store at least six or seven times the amount repellent falcon can take and between two to three times as much as the Falcon Heavy SpaceX is now testing a new prototype of the super heavy the booster 7 or b7 after confirming the b4 would be giving away for the b7 in fact musk did confirm on Twitter that the booster 4 and chip 20 would no longer be used for the first orbital flight following months of assumptions that the pair would be used the process of stacking the new prototype took about 11 weeks b7. The prototype to carry 33 of the new version 2 of the Raptor rocket engine the b4 before it had 29 version 1 rocket engines the raptor v2 is a significant simplification of the original raptor's design making it easier to build install and operate it also substantially boosts maximum thrust from around 185 tons or about 410 000 pound-foot to at least 230 tons or 510 000 pound-foot so with a super heavy b7 outfitted with a full 33 raptor v2 engines it's capable of operating at that claimed thrust level booster 7 could theoretically produce at least 40 per cent more thrust than booster 4. The course, the b4 never got to attempt a single static fire with the move to b7 SpaceX decided to qualify the new raptor v2 with a new prototype which will not be strange to people that have been watching the development of the f booster 7 comes with lots of design changes starting from sleeker raceways these are external conduits that protect wiring and smaller plumbing the prototype also uses a different layout of the pressure vessels hydraulic power units and umbilical panel installed on its aft.
That may indicate it is ready to start installing the rocket engines the process started with at least one pneumatic proof test the likely saw booster 7 pressurized with a nitrogen gas SpaceX filled the booster to about a third of the way with roughly 1000 tons or 2.2 mega pounds of liquid nitrogen or a combination of liquid oxygen and liquid nitrogen once the rocket was fully chilled there were clear signs of some kind of added stress as large sheets of ice that had formed on the side of b7 skin broke apart and fell off going by the physical and visible evidence it appears the stress was caused by pressurizing super heavy.
The amount of pressurization gas required makes it much easier to ensure that super heavy's raptor engines are fed with an uninterrupted propellant flow during space and the atmosphere.
