Original title: US SpaceX “Xingzhou” SN8 exploded during its second test flight and landing

On December 9 local time, US space exploration technology.the company(SpaceX) developed the SN8 “Xingzhou” heavy duty launch vehicle for the second test flight in Texas. “Xingzhou” SN8 launched into the air and landed slowly. Upon landing, the rocket exploded. The entire flight lasted 6 minutes and 42 seconds.

SpacexExecutive DirectorMusk said on social media that day, although the test flight blew up in the final stage, “we got all the data we needed.” Musk called this a “successful launch.” He said the fuselage and flaps precisely guided the rocket to the landing site, Musk said whenmotivationDuring re-ignition and landing, the fuel tank pressure was too low, causing the “Xingzhou” SN8 to land too fast.

Currently, SpaceX has not disclosed that the “Xingzhou” SN8testThe original plan was to fly at an altitude of 8 miles and then slowly descend vertically.

The mission was carried out in Boca Chica, located in the border area of ​​southeast Texas. SpaceX built the “Xingzhou” R&D and test base locally.

According to the technology medium “Space”, “Xingzhou” SN8 is the prototype of the heavy duty launch vehicle “Xingzhou” being developed by SpaceX. As a large-scale stainless steel prototype, it is 160 feet tall and approximately 30 feet in diameter. The prototype has a more complex structure than the previously tested prototype. It has a nose cone, fin, and three “Raptor” engines. Its flight altitude can reach 100 times that of the prototype tested earlier. In August this year, the prototype SN5 “Xingzhou” successfully conducted a test flight at an altitude of about 500 feet in Texas.

　　InlandAccording to the agency, SpaceX conducted flight tests on the “Xingzhou” SN8 for two consecutive days. On the test flight on day 8, at least one Raptor engine was abnormal before takeoff and stopped automatically.jobs。

According to Reuters, the “Xingzhou” heavy launch vehicle will consist of two parts, one is a stainless steel spacecraft called “Xingzhou” and the other is a “super heavy” rocket booster. The entire aircraft will reach a height of 394 feet, which is 31 feet higher than NASA’s “Saturn 5” rocket. “Xingzhou” is designed as a spaceship that can carry 100 people at a time and can carry a large number ofSuppliesFly into space. SpaceX developed this new recyclable rocketgoodsSent to the Moon and Mars. In addition, “Xingzhou” will also be used to transport large satellites to Earth orbit. (End up)
