The explosion of the Falcon 9 occurred because of the solid oxygen.
SpaceX engineers have established the exact cause of the recent explosion of the Falcon 9 rocket and preparing to resume flights by mid-December.
The founder and head of SpaceX Elon Musk called the crash “the most difficult puzzle” of those with whom they happened to encounter. Now, when it became clear that the cause of the explosion – cold liquid oxygen, the company expects to resume launches of Falcon 9.
According to the Mask, the explosion that destroyed the rocket and its contents, were called “really awesome problem that never occurred before in the history of rocketry”.
As it turned out, the explosion occurred around tanks of carbon composite materials with liquid helium in the tank with the liquid oxygen in the upper stage of the rocket. As noted by Musk, as a result of chemical reactions formed solid oxygen which reacts with carbon composite materials tanks. In other words, perhaps the coating that protects from oxygen was very thin and it has damaged the crystals formed in liquid oxygen.
