Share with friends and circles of friends with wechat scanning QR code < / P > < p > on August 26, 12 days after SpaceX's super heavy booster B4 booster returned to the high cabin of the factory from the orbital launch pad, engineers began to install 29 Raptor engines again, paving the way for possible orbital flight tests in the future. It is reported that this is also the second time this month that SpaceX installed Raptor engine for B4 booster. At this time, it is just 11 days since engineers removed the engine < p > < / P > < p > on August 1, SpaceX began to install multiple Raptor engines at a very high speed just after installing a grid wing the size of a car on the B4 booster. Less than 24 hours later, 29 Raptor engines were connected to the propulsion structure of the super heavy rocket < p > just one day later, the B4 booster was transported and installed on the newly built orbital launch pad. Four days after the B4 booster completed the Raptor engine installation, engineers assembled the S20 starship and B4 booster to form a complete starship launch system, which is also the highest and largest rocket in history. But this state lasted only an hour. SpaceX will remove the S20 and B4 boosters from the launch pad and return to the factory for further operation < p > since the B4 booster returned to the high cabin on August 11, engineers first removed 29 Raptor engines on the booster, and then have been trying to lay kilometers of pipes and cables for the 69 meter high giant rocket booster < p > now, just 11 days after the engineers quickly removed the Raptor engine, SpaceX has begun to reinstall Raptor on the B4 booster, and there are several engines that were not installed last time. It is reported that when SpaceX first installed the Raptor engine on the B4 booster, at least five had never been tested, which made it almost inevitable for engineers to install and disassemble the Raptor engine. In fact, as expected, SpaceX will install several new Raptor engines on the B4 booster this time < p > considering that a series of matching checks have been completed on the B4 booster, this means that SpaceX will conduct the first static ignition test on the booster after installing 29 Raptor engines. Of course, the static ignition test may cause problems and even damage some Raptor engines < p > after the engine is installed, SpaceX will send the B4 booster from the high cabin to the launch pad for the second time, which may be completed in the next week or two. Engineers may install the B4 booster on the second suborbital test-bed next to the S20 starship, but it may also return directly to the orbital launch pad（ Chen Chen) < / P > < p >
