On November 26, the construction of SpaceX's first starship launch tower has entered the final stage, and the company is expected to start testing the Starship launch system next month < p > < / P > < p > giant manipulator < / P > < p > in the past two weeks, SpaceX has installed a pulley system that can move up and down for the giant manipulator of the launch tower, and laid the steel cable for hoisting the manipulator in the launch tower. By November 9, technicians had fixed the steel cable on the giant manipulator, which could bear the huge weight of the giant manipulator < p > however, SpaceX has not completely installed the mechanical arm, and the steel cable used to move the mechanical arm up and down is still loose. After all, technicians will debug the manipulator itself to ensure that its hydraulic, electrical and mechanical systems can operate normally < p > in the future, these giant mechanical arms will be used to grab, lift and install super heavy boosters, stack and assemble starships. SpaceX also plans to use the mechanical arm to recover boosters and starships in mid air < p > quick connect arm < / P > < p > in addition to the giant mechanical arm, SpaceX has basically installed the quick disconnect arm in the middle of the launch tower recently. The quick disconnect arm is designed to fuel the Starship and stabilize the super heavy booster from the top. It can open and close left and right, move up and down, open quickly during rocket launch, and make room for the movement of giant robotic arms when the launch tower captures boosters or stacks starship systems. Last week, SpaceX technicians connected more than 1000 meters of insulated steel pipe from the quick disconnect arm to the propellant storage tank of the launch pad. On November 23, SpaceX completed the installation of a quick disconnect mechanism that can be connected to the Starship < p > at present, the quick disconnect arm also needs to install some small drivers and be fully connected to the launch pad through various pipelines < p > orbital launchers < / P > < p > in addition, SpaceX has conducted many tests on circular orbital launchers. This huge steel structure is located at the bottom of the launch tower. The Starship system will be located on the orbital launch pad before test and launch. The launch pad will also provide thousands of tons of propellant for the Starship system. On November 21, SpaceX completed its first test of the launch pad and seemed to release an unknown gas. This is likely to be the first simultaneous test of the base frame for gas supply of all 20 outer ring Raptor engines of the booster. The Raptor engine of super heavy booster will rely on the gas supply of the launch pad for ignition during launch. Each Raptor engine has a small connection and quick disconnection mechanism, which may be the most complex rocket launch pad in history < p > on November 22, technicians also started the quick disconnect device installed on the orbital launch pad for the first time. To prevent the components of the quick disconnect device that delivers fuel to the Raptor engine from being burned during each rocket launch, the device needs to be quickly away from the super heavy booster before the rocket takes off < p > when the Raptor engine propels at full speed, it will produce plumes with temperatures up to several thousand degrees. There is a protective cover in the launch pad mechanism connected to 20 Raptor engines to ensure timely shutdown at the moment of rocket launch < p > in the past week, SpaceX also began to install corresponding pipes on the launch pad, and spray systems may be assembled around it to help cool down and reduce noise during rocket ignition and launch < p > after the construction of the first starship launch pad, as long as the liquid methane is transported, the Starship system can officially start testing.
