Starship is a next-generation rocket with a total length of 121 meters. In the 5th flight test conducted on October 13, the spacecraft successfully caught and recovered a large booster (propulsion device) that returned to the launch site after separating from the spaceship using two rod-like facilities. In the upcoming "Flight 6", aside from catching the booster again, experiments on re-igniting the engines and testing the heat shield will also be conducted. It is expected that by improving the structural strength of the booster,Expectations are high for opening the path to reuse.
