Explosion during test of 4th Starship prototype
Capitalism in space: SpaceX engineers experienced another explosion during testing of their fourth Starship prototype today, completely destroying the protoype.
They already have their fifth prototype almost complete, so I expect they will clean up the debris, analyze again what went wrong, and start testing again.
At a certain point however these explosions have got to end, or else the project will begin to be in trouble.
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.

Despite its being an obvious happy compromise between Isp and density, liquid methane/LOX had never seen much development before SpaceX. They are basically pioneering the large-scale implementation of this prop combination. So they are going to come up with some new failure modes, as they already have with COPVs and the chemistry of titanium.
I’m amazed at just how volatile this prop combo looks to be. It’s scary! But they are going to conquer it.
If each explosion occurs further along in the test sequence, then the project is not in trouble.
It sure packed a punch.
Patrick: Your comment reminds me of Manly Wade Wellman’s short story in the June 1938 Astounding Science Fiction, “Men Against the Stars.” Manned rockets, using an unstable atomic hydrogen fuel, blow up traveling to Mars from the Moon.

How many Falcon 9’s crash landed in the early attempts of the impossible?
SpaceX solved those problems and have LANDED 44 of 52 attempts.
The SpaceX Starship (or something very similar) will be earth’s first true Spaceship.
Thank you Mr. Musk.
I had often noted the extremely robust appearance of the test stand, apparently constructed of steel I-beams of 10/12-inchs width or more. Post-explosion I saw no trace of it. Ho Li Kow!

Good stuff.

Mark McSherry, as a long-time sf reader, your comment made my day. I’ll definitely dig into that web site.

It looks like an O2 venting from either a busted line, hose or even the tank.
It didn’t ignite until several seconds after the venting started.
And it looks like the flame front came from the burn off stack and not the rocket itself.
they are going to have to move the burn off stack farther away and maybe add a water mist system to help keep any accidentally vented O2 or methane from staying too concentrated.
High speed cams would help a bit.
I have to agree with Mr. Zimmerman that unless they stop these ongoing issues with testing , the starship program will be in trouble. I honestly have been having doubts about their approach to the starship development efforts. I hope they can prove me wrong in the long run.
Thanks Wayne!
Funny that SpaceX is attempting to launch Bob-n-Doug this morning, a day after blowing up a rocket!
Go Bob-n-Doug!
I disagree with your last statement, Mr. Zimmerman. I think the explosions (failures) allow SpaceX to quickly learn what improvements are needed. The way I see it, the more explosions, the better.

Jason Hillyer: I actually agree more with you than myself. I just thought it important to note that at some point, they need to get past the fueling, pressurization, and static fire tests and actually start the first hops.
