SpaceX announced the cause of the Falcon 9 rocket exploding

On June 28, SpaceX launched the Falcon 9 missile in its third attempt to land landing. Unfortunately, the test failed more than twice before, when the Falcon 9 rocket exploded shortly after it launched a few minutes.

The cause of the Falcon 9 rocket explosion has been announced

Exactly after 2 minutes 19 seconds, the Falcon 9 rocket exploded. SpaceX made 18 launches of this missile, and this is the only time the missile exploded.

Falcon 9 caught fire for technical reasons when taking off.

At first, Elon Musk said: " There has been a sudden increase in pressure in the liquid oxygen tank of the top stage of the missile. The data have suggested an unusual sign . what is it? We can confidently confirm at this time. There will be more details after we analyze the failure chart. "

Yesterday, the owner of SpaceX said that after conducting the investigation, he and his colleagues agreed on the cause of this explosion is the steel bar that is responsible for fixing valves of helium gas cylinders. in the second engine floor it broke, so helium gas spilled into the liquid oxygen tank. This changes the pressure of the fuel tank and only one ignition will cause it to explode.

Elon Musk said these steel bars were provided by third parties that he did not mention, unfortunately they did not meet the quality requirements when the technical requirements of these steel bars had to withstand a force of 45000 Newton. while it was broken with only a force of 9000 Newton. Elon Musk also said SpaceX will find another partner on this issue.

The Falcon 9 rocket is an upgraded version with a more efficient, extended fuel tank system, lighter engine and a new flight control computer system. It brought the Dragon transport ship with 1,800 kg of equipment and supplies to the ISS space station , which included an important adapter system (International Docking Adapter - IDA) to support the mounting of spacecraft. Future of America with stations.

The second IDA system was scheduled to be launched by Dragon transport in September this year but after the incident, the schedule will be delayed. In addition, SpaceX's plans to take people to space are also suspended, waiting for the company to complete the technologies needed to be able to reuse the rocket engine.
