SpaceX investigation into test explosion ongoing
A NASA update yesterday into SpaceX’s investigation into the test explosion that destroyed a manned Dragon capsule revealed that while the company is still working to launch humans by the end of the year, this schedule remains tentative until the investigation is completed.
The update included two important details. First, SpaceX is going to use for its launch abort test the Dragon capsule it had previously planned to fly on its first manned demo mission, and for that mission will use the capsule intended for the first operational manned flight. That first operational flight will then use a new capsule from their assembly line.
Second, the update confirmed that the anomaly that caused the explosion occurred as they were activating the SuperDraco thruster system, but prior to the firing of the thrusters. While this suggests once again that the failure might have not have involved the capsule but the test procedures, we will not know for sure until they release their investigation conclusions.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

That says…. almost nothing. Of course they’re going ahead with production. That leaves an unstated assumption that if a hardware issue is found, that the parts involved can be accessed and replaced on a capsule that has completed assembly.
The chain of events between activation of the SuperDracos, and firing of the SuperDracos, has to be pretty small. Yes, that leaves test procedures open to question, but also tanks, pressurization, pumps, valves, and all the rest of the plumbing. Also sea water contamination, refurbishment, and reassembly, as well as any testing that was or was not done after refurbishment but before the full systems test.
So, pretty much a nothingburger. They probably know more, but nothing conclusive, and/or nothing they will say in public.
I suspect nothing will be said in public until the investigation is complete. But I’ve heard that they knew the cause of the explosion pretty much instantly, and have been working root cause analysis. The last word I heard is that they believe they have the root cause, but are working to prove it and check some alternate theories, and are close to done on that. I haven’t heard anything at all as to what they believe the proximate or root causes to be though.
