Elon Musk recently revealed some details about the future testing of SpaceX, the SN8 prototype will have a nose cone and attempt a 60000 foot return flight. The company is currently developing SpaceX launch vehicles at its plant in Boca Chica, Texas. Recently, SpaceX has completed short-range, 150 meter (slightly less than 500 feet) test flights of two early starship prototypes SN5 and SN6. The SpaceX prototype, which has undergone so-called “short jump” tests over the past few weeks, has taken off and landed, but it has installed a dummy weight on top of the actual dome nose cone that should have been installed on top of the final starship to protect all cargo on board. < p > < p > as we all know, SN5 and SN6 are usually compared to granaries, but they also lack large control flaps on both sides of the nose, and the function of the control flaps is to help control their flight. < / P > < p > This version of the prototype will also undergo the same early and precursor tests, including static fire and other ground tests, and then conduct a static fire test, eventually trying to fly to 60000 feet (about 20km), flying to the stratosphere, and then returning to the ground for controlled landing. Previously, SN5 and SN6 were both made of 301 stainless steel, while sn7.1 was made of 304L (or at least a variant of this alloy). The SN8, also made of 304L alloy, will help test SpaceX’s starship launch system (SLS), most notably with three Raptor engines. < p > < p > as SN8 continues to be the first complete starship, sn9 has also begun to appear. In a large tent at the SpaceX production site, there is a dome part, which may be one of the most difficult parts for the spacecraft to build. According to the sun, musk plans to send humans to Mars in 2024 and build a self-sufficient city on Mars by 2050. According to the report, SpaceX recently completed the second “jump” test of its starship rocket prototype, with the goal of taking astronauts to the moon, Mars and other places using starships. < / P > < p > we have to build a city and be self-sufficient. I want to stress that this is a very dangerous and difficult thing. This is not a coward, because it is likely to die. It’s hard, but if it works, it will be very glorious. In order to achieve the goal of Mars City, musk has outlined a rough timetable for himself. < / P > < p > first SpaceX announced that it was developing an ultra heavy rocket booster that could be tested before the next spaceship event in October. However, musk said in an interview with the station: “the original idea may not work. This is an unknown area. No one has ever built a fully reusable full orbit rocket. It’s very important to have it all. ” After that, musk hopes to send Japanese billionaire Yusaku maesawa and six to eight artists around the moon in 2022. The CEO also revealed that SpaceX plans to build 1000 starships in a factory in southern Texas within 10 years. If what he said is true, it is that at least 100 Rockets need to be built every year. < / P > < p > in the end, our goal is to launch 1000 spaceships to Mars every year – an average of three times a day. Each trip will have 100 passengers to the red planet and become citizens of the Martian mega city. According to a report by techrush, an American science and technology media, SpaceX’s pace in the development of starship is actually somewhat backward compared with Musk’s earliest and most optimistic prediction. However, the CEO’s estimation of the time frame is too optimistic, which is a fact that he has to admit despite his unwillingness to admit. < p > < p > the development of rockets is notoriously difficult, so there is still a high probability that the first attempt to fly at high altitude will fail. In particular, SpaceX’s development program focuses on rapid iterations, learning from early mistakes, and building concurrent development prototypes that include different lessons learned from different generations of products. Although it may not have a timetable to drive musk crazy, it’s moving very fast, especially now that the latest prototypes have withstood stress tests and launched. Global Tech
