Its mission is to put the Starship into orbit, which will be the most powerful rocket booster ever built. Equipped with up to 28 Raptor engines, it can generate more than 7300 tons of thrust at launch, more than twice and three times higher than the Saturn V and SpaceX Falcon heavy rockets, respectively. < / P > < p > previously, SpaceX's plan was to recover the super heavy rocket booster in a way similar to Falcon 9 and Falcon heavy rocket booster, and let it land on an unmanned recovery ship at sea, or return to the < a target = "launch pad near the launch pad_ blank" href=" https://news.163.com/news/search?keyword=%E7%9D%80%E9%99%86 "> land on the < / a > mat. But after a lot of design improvements, SpaceX now hopes to land the super heavy rocket booster directly on the launch pad. According to musk, SpaceX will try to use the launch tower arm used to stabilize the launch vehicle in preparation for takeoff in midair, and "capture" the super heavy rocket booster currently under development in midair. Musk said that when the current Falcon 9 rocket booster returns to earth, it completely relies on the built-in landing leg to push the landing, but the super heavy rocket booster has no similar design. < / P > < p > the super heavy rocket booster will still use the engine to control its landing speed, but it will involve using the grid wings on the main body to help control the flight direction and hook the booster with the launch tower arm before it completely touches the ground. < / P > < p > of course, this recycling method requires higher accuracy, and may bring new risk factors, or require very strong recycling hardware facilities. However, the benefits are also significant. SpaceX does not need expensive asset recovery, time-consuming transportation, or even the need to lift the super heavy rocket booster from the landing area near the launch pad back to the launch pad. < / P > < p > another potential benefit of Musk's proposal is that this design allows SpaceX to basically immediately recover the super heavy rocket booster and return it to the launch pad. SpaceX only needs to be ready to use the new payload and can be launched again in less than an hour. < p > < p > SpaceX's goal for starships and super heavy rockets is to create a carrier rocket that is easier to reuse than the current Falcon 9 rocket system. In the end, musk wants the spacecraft to perform regular and frequent missions, point-to-point flights on earth, missions in orbits closer to home, and long-distance interstellar missions to the moon and even Mars. < / P > < p > Musk's goal is to enable human beings to settle on Mars, which also requires the rapid recovery and reuse of super heavy rockets as his new recovery method proposed today. The prototype of the starship is currently being built and tested in boccachka, Texas, USA. SpaceX is also studying the components of the super heavy rocket booster. Musk recently said that he plans to start flying super heavy rocket boosters in a few months.
