Elon, CEO of SpaceX_ blank" href=" https://news.163.com/news/search?keyword=%E9%A9%AC%E6%96%AF%E5%85%8B "> Elon Musk commented shortly after the test that the short static ignition test was intentional. < / P > < p > it is worth noting that this is the first time that SpaceX has completed three static ignition tests of starship prototypes in one day, not to mention that two of them were only less than two hours apart. The fact itself has proved that sn9's first transient static ignition test is actually successful. Because SpaceX is unlikely to redouble its efforts on failed tests and risk prototype damage unless it can immediately determine the cause of the failure. < / P > < p > musk recently said that SpaceX is now evacuating the fuel in sn9 to ensure that the prototype and related facilities are safe for inspection. If sn9 and its three Raptor engines are in good condition after the above tests, SpaceX may launch at an altitude of 12.5km on January 14 or 15, local time in the United States at the earliest.
