The recent loss of the Falcon 9 and its payload during group preparations for launch was highlighted by Elon Musk of SpaceX by this tweet on September 1, 2016:
Loss of Falcon vehicle today during propellant fill operation. Originated around upper stage oxygen tank. Cause still unknown. More soon.
Difficult, complex failure
A burst of new tweets on the mishap from Musk are:
- Still working on the Falcon fireball investigation. Turning out to be the most difficult and complex failure we have ever had in 14 years.
- Important to note that this happened during a routine filling operation. Engines were not on and there was no apparent heat source.
- Support & advice from @NASA, @FAA, @AFPAA & others much appreciated. Please email any recordings of the event to report@spacex.com.
- Particularly trying to understand the quieter bang sound a few seconds before the fireball goes off. May come from rocket or something else.
