But at that time, the fog weather and the failure of the camera led to the explosion of sn11 is complicated. On Monday morning, SpaceX founder and CEO Elon_ blank" href=" https://news.163.com/news/search?keyword=%E9%A9%AC%E6%96%AF%E5%85%8B "> musk < / a > (Elon Musk) revealed some details of the sn11 explosion by tweeting, which attributed the sn11 explosion to fuel leakage. < / P > < p > musk wrote on Twitter: "a very small methane leak caused the No. 2 Raptor engine to catch fire and burned down some avionics equipment, which led to the explosion at < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E7%9D%80%E9%99%86 "> hard start of CH4 turbopump ignited during landing < / a > (internal pressure higher than preset value)" < / P > < p > musk also added that the attitude control of the sn11 prototype during its ascent, flight attitude turning to horizontal position and free fall of the spacecraft prototype is very good. < / P > < p > the prototype sn11 was launched from SpaceX's spaceship R & D center in Texas on March 30 local time, when the ground visibility was almost zero. At first, everything went well. Sn11 rose to an altitude of about 10 kilometers above the earth, and then returned to earth. The prototype of the spacecraft then carried out a landmark flip maneuver in the air. After preparing for landing and ignition, the onboard camera suddenly failed during the live broadcast. < / P > < p > other remotely operated real-time cameras aimed at the landing site from nearby, caught orange light in the fog, and then debris fell around the landing site like a rainstorm. < / P > < p > two earlier starship prototypes, SN8 and sn9, both hit the ground and exploded due to hard landing. Sn10 made a successful landing, but collapsed and exploded on the landing platform a few minutes later. Sn11 seems to be the first starship prototype to explode before hitting the ground. It is reported that SpaceX will start testing sn15 directly. It is reported that sn15 has carried out a series of upgrades to the original spacecraft prototype, and musk is very excited about this. He chose to give up sn12, sn13 and sn14. < / P > < p > sn15 has been assembled and is ready to continue a series of tests before its debut. Sn15 is expected to successfully complete the high-altitude flight test and successfully land safely. It may also enable the company to start the first orbit flight of the starship in June. < / P > < p > musk said that the methane leak that led to the explosion of the spacecraft prototype last week will be repeated. < / P > < p > he tweeted: "as of Sunday, we have six solutions to this problem."
