On Friday SpaceX CEO Elon Musk said that it has been more than a week to a launch pad explosion that shattered a Falcon 9 booster and an Israeli communications satellite, but the company-led investigation hasn’t found the cause of the mishap so far.
Musk posted a series of tweets, saying that SpaceXhas been working on the Falcon fireball investigation. The founder called the inquiry as the most difficult and complex failure they have ever come across in 14 years.
On September 1, during fueling for a preflight ‘static fire’ test, the 23-story Falcon 9 rocket’s upper stage blew apart all of a sudden at Cape Canaveral. It happened roughly eight minutes prior to the projected ignition of the first stage’s nine Merlin 1D engines for some seconds while the booster stayed tightly restrained to the ground.
On the basisstandard practice on past SpaceX missions, at that point in the countdown, the propellant tanks’ Falcon 9 rocket were typically not yet pressurized for ignition.
On September 2, SpaceXreleased updates indicating that the problem first appeared near the liquid oxygen tank on second stage of the Falcon 9 rocket. The Falcon 9’s both stages burn the blend of RP-1 kerosene and liquid oxygen propellants.
USLaunchReport.com captured footage of explosion from some miles away from Cape Canaveral’s Complex 40 launch pad. It showed that the light from the fireball initially appeared around the upper stage, just under the nose cone of the rocket containing the Amos 6 communications satellite that belonged to Israel’s Spacecom Ltd.
While referring to the video on Twitter, Musk wrote, “Investigators are particularly trying to understand the quieter bang sound a few seconds before the fireball goes off. May come from rocket or something else”.
