As of Thursday afternoon local time, the company had obtained the approval from the Federal Aviation Administration of the United States (< a target = "_ blank" href=" https://news.163.com/news/search?keyword=FAA "> FAA < / a >) will be authorized in boccachica, Texas at < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E5%8F%91%E5%B0%84%E5%9C%BA "> launch site < / a > conducted three flight tests on the Starship prototype. Previous flight tests conducted by SpaceX were submitted to FAA for approval. But the FAA said in a statement that the three tests were packaged and approved because "SpaceX did not make significant changes to the launch equipment and relied on FAA approved methods to assess the risks faced by the public." SpaceX will test the spaceship sn15 as early as this week on the premise that FAA inspectors are present to supervise the launch. FAA said one of its inspectors is expected to arrive at the launch site today, which could pave the way for possible flight tests in the next few days < p > SpaceX's last flight test in boccachka was to launch sn11 at the end of March this year, but the test results were very poor. Sn11 rose to the predetermined altitude of 10km above the ground and completed the maneuver reversal, but < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E7%9D%80%E9%99%86 "> during the landing < / a >, the Raptor engine had a problem, which caused the spacecraft to explode violently < p > in a statement approving space to conduct three tests, FAA said it was still investigating the failure of sn11 test. But the agency added that the FAA was able to confirm that SpaceX had addressed public safety issues related to the accident < p > the three launch permits include flight tests of sn15, sn16 and sn17. However, FAA pointed out that after the first flight test, the next two launches may need to take additional "corrective measures" before the actual take-off of the spacecraft to prevent any "accident" after the sn15 launch SpaceX pursues fast iteration and test speed in the process of starship development. Elon Musk, the company's chief executive, has criticized the FAA for not being flexible or responsive to SpaceX. On the other hand, some U.S. congressmen said that the FAA may not be thorough enough in its independent investigation of the early accidents of starship prototypes. However, according to FAA, SpaceX's testing did not affect public safety in the end, indicating that its plan has worked so far（ Chen Chen) < / P > < p > <-- EndFragment-->
