"Falcon 1 Failure Traced to a Busted Nut". Following the explosion, SpaceX has switched to performing static fire tests only without attached payloads. SpaceX released an official statement in January 2017 indicating that the cause of the failure was a buckled liner in several of the Composite overwrapped pressure vessel (COPV) (used to store helium which pressurize the stage's propellant tanks), causing perforations that allowed liquid and/or solid oxygen to accumulate underneath the lining, which was ignited by friction. The pad was clear of personnel, and there were no injuries. The rocket and the AMOS-6 payload were lost in a launch pad explosion on 1 September 2016 during propellant filling procedures prior to a static fire test. ( more details below) The drone ship Of Course I Still Love You was towed out to sea to prepare for a landing test so this mission was its first operational assignment.

Dragon capsule survived the explosion but was lost upon splashdown as its software did not contain provisions for parachute deployment on launch vehicle failure. Launch performance was nominal until an overpressure incident in the second-stage LOX tank, leading to vehicle breakup at T+150 seconds. NASA stated that this was because SpaceX could not guarantee a high enough likelihood of the second stage completing the second burn successfully which was required to avoid any risk of secondary payload's collision with the ISS.
This was due to one of the nine Merlin engines shutting down during the launch, and NASA declining a second reignition, as per ISS visiting vehicle safety rules, the primary payload owner is contractually allowed to decline a second reignition. ĬRS-1 was successful, but the secondary payload was inserted into an abnormally low orbit and subsequently lost. Residual stage-1 thrust led to collision between stage 1 and stage 2. Premature engine shutdown at T+7 min 30 s. Successful first-stage burn and transition to second stage, maximal altitude 289 km. FalconSAT-2 landed in a storage shed near the launch site. Orbital launch attempts Falcon 1 Flight No.Įngine failure at T+33 seconds.
