SpaceX Falcon 9 explosion took the world by storm with alien enthusiasts predicting that a UFO triggered the explosion of the spacecraft. Now, a preliminary investigation carried out by the company has revealed that a huge breach in the helium system caused the accident.

SpaceX made the revelation in an update published on Sept. 23, Friday. The company also revealed that the recent Falcon 9 explosion has nothing to do with a similar explosion that took place in 2015, when a Falcon 9 spacecraft exploded two minutes after lift-off.

The company believed that "a large breach in the cryogenic helium system of the second stage liquid oxygen tank" led to the explosion. Thorough investigation and preliminary review of all the data and debris discarded any connection with the CRS-7 mishap, which occurred due to a problem with the steel strut used to keep high-pressure helium tank down.

The officials further stated that the company is carefully analyzing the fault tree. A team of experts from four different organizations - NASA, SpaceX, the Federal Aviation Administration (FAA) and US air force - is still trying to solve the mystery behind the explosion and the reason that led to the breach.

SpaceX further showed its concern over the possible delay in the rest of its mission. The recent mishap has damaged a large area of its launch site in Cape Canaveral, Florida, which could impact the schedule of other scheduled launches this year.

A group of alien hunters and UFO enthusiasts previously claimed that two passing UFOs led to the SpaceX Falcon 9 explosion. According to a report published by The Express, alien conspiracy theorists claimed that two weird objects flew past the Falcon 9 rocket in the background just before the explosion took place.

Later, a video surfaced that showed strange activity going on around the SpaceX launch pad. The conspiracy theorists claimed that the aliens are particularly interested in SpaceX launch.
