THE ILL-FATED MORNING of September 1 saw the explosion of a SpaceX Falcon 9 rocket just before a routine pre-flight ignition test. The world saw the 277 foot-tall space vehicle and its $200 million satellite burst into flames and disappear forever, just like that. After that, there have been obvious repercussions for SpaceX, as well as several theories floating around on the cause of the explosion. Elon Musk, CEO of SpaceX, called it the toughest problem as yet and even went to the extent of pinning the accident on sabotage by the rivals and some “keen” observers speculated the fail to be related to a UFO attack.
But it seems as though SpaceX has finally narrowed down its search, as this Friday, the Wall Street Journal reported that the cause of the explosion might just be operational, and not any “alien attack” or a manufacturing/design flaw of the rocket. The investigation behind the explosion involves collaboration between SpaceX, the FAA, NASA, the US Air Force, and industry experts. They have been looking at over 3,000 channels of engineering data, footage, along with video and audio evidence.

Lately, the investigation has bene more focused on the cryogenic helium system inside the liquid oxygen tank, which is required to move the rocket and its cargo manoeuvre from Low Earth Orbit into Geostationary Transfer Orbit. But even this discovery still leaves many other questions unanswered.
Scott Pace, director of the Space Policy Institute at George Washington University, remarked on the issue. He was of the view that it is yet to be determined whether this was a design flaw or due to negligence or anomaly in the pre-flight process. He said,
“It could be good if it turns out to be an operational problem, because that is easily remedied, rather than a design or manufacturing problem. But you have to ask why did that operation failure happen. Was their lack of training or understanding of what was going on? have proof that the fueling failure was what occurred, or did they eliminate other faults and the fueling operation what was remained? Was it that people felt rushed? Was there schedule pressure, were they doing something innovative. Was it something else?”
Officially, SpaceX has been uncharacteristically silent on the issue. The following statement is the most elaborated one coming out of SpaceX till date,
“a preliminary review of the data and debris suggests that a large breach in the cryogenic helium system of the second stage liquid oxygen tank took place. At this time, the cause of the potential breach remains unknown.”

NASA and FAA, the other members in the investigation, have also been rather coy and have been ducking under the firing questions, raising the speculation. The investigation would not be very easy, given the incredibly complex nature of the systems involved as well as the extremely short timeline of the explosion, which is recorded to be only 93 milliseconds or less than 1/10th of a second.
If this explosion would have happened when the rocket was launching, or in flight then more data would be available courtesy the thousands of streaming cameras and additional sensors feeding into flight control computers.
SpaceX has only lost two of its 29 launches, and even after the setback, the seem unfazed and continue to sign up new customers. But whether these customers should be worried, there is no conclusive answer for now.
