Another successful Starship prototype hop
Capitalism in space: SpaceX today successfully completed a 150-meter high hop of its sixth Starship prototype, the second such hop but the first for this prototype. They have now flown two different prototypes, plus Starhopper, all successfully. No flight failures, so far.
Next they will be doing a pressure tank test, to failure, of the seventh prototype. That prototype is using what they think will be a better steel alloy, and they want to find out its limits. I have also heard that they will either fly this prototype again or fly the fifth again, sometime in the next two weeks.
I have embedded a few more images below the fold.
To the right a close-up, shortly after take-off. The single Raptor engine at the base is tilted slightly to compensate for the vehicle’s overall tilt as it slides leftward to its landing site. Note the stubby legs at the base.
The first image below is a long shot showing the prototype shortly after the smoke cleared, sitting safely on the ground. Like the fifth prototype, the sixth is also leaning slightly, though as much.
The last picture is a close-up shortly after landing. You can see a fire at the prototype’s base. Fire suppression equipment quickly put this out.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

It looks amazing and silly at the same time. Amazing, because of what they are doing and where they are going with the technology. Silly, because it looks like they have built a flying silo. Of course the first Wright Brothers flight probably had that same feel.
That looks more like a fire under the rocket, rather than a ground fire, but it’s definitely a fire. I was remembering earlier static fires and launches, setting fire to grass in surrounding land. At least one of those burned overnight and was out of control, burning close to housing. (Not to mention SN4’s detonation.) So they’re getting better at containing fires and clearing the launch and landing areas.
This has been a concern of mine for a while; methane would seem to be much more of a fire hazard in these circumstances than either RP-1 or hydrogen. I do hope that ULA and Blue Origin are learning from this.
Not a ground fire, the vehicle is on the concrete pad. It’s still venting what is probably methane two hours later from the area where the fire was. Need to plug that leak for next time. What is so great about this is that they have the opportunity to fix it and test it again, unlike the NASA days of discarding the hardware after every test.
Tjohoo! The ugliest thing that ever flew with rocket power.

In 1983 crewed Soyuz T-10-1 leaked kerosene on the launch pad and caught fire. It burned for 22 seconds (if I remember correctly) until the capsule made a launch abort. It was ordered immediately, but the first thing that happened was that the communication cables connecting the launcher with the ground burned up. And it took the Soviets that long to send the command by radio, because of their cumbersome routine for that plan B. A couple of seconds after the crew lift off, the boiling oxygen tank burst and everything exploded.

I think you’re right that methane burning in the atmosphere doesn’t have that kind of natural safety margin. City gas is methane mixed with something else. As a student a course mate invited me and others for dinner in the old apartment where she rented a room. When she thought the stuff in the gas oven was ready, she discovered that it hadn’t even been lighted. So she lit it then, filled with gas that had been streaming for a while. BOOOM! Pictures fell from the walls, glasses fell over. But no injuries, other than a ringing sound in the ears for a while. (A neighbor died from heart attack, but that was a couple of days later and probably unrelated, probably.) It was immediate, not like lighting a pool of kerosene of even gasoline that just starts burning.
I once took a course in chemistry, very laboratory intensive which made me realize that I’m more of a theories kind of guy. And that chemists are crazy. We were always boiling things in acids to clean them. So I turned up the Bunsen burner with butane gas in the fume cupboard and tried to light it with the spark lighter. Nothing happened. Tired and late with my lab report and my thoughts elsewhere, I guessed that there must be something wrong with the spark lighter (how could it be, it sparked, stupid!) So I walked around looking for another one. I hadn’t turned on the fan because I thought why do that until there’s any smoke and fumes to get rid of? This time I put my head inside the fume cupboard to check that the lighter really sparked. Of course, there was a second Bunsen burner in the same fume cupboard, with their hoses intertwined. I had opened the other one that by now had filled the cupboard with butane gas. Scratch BOOOM! I got away with my eye brows burned off. The next day a small child watched me terrified and hugged his mother’s leg in the grocery store. One does look very very strange without eye brows, and it isn’t immediately obvious to people what is missing. And butane is less explosive than methane. It explodes nicely in thin air without the help of liquid oxygen, I know.
I must add that when I put my head inside the fume cupboard, I felt the smell of gas. I thought, at least that works! Scratch…
LocalFluff, good stories!
Our chemistry lab in high school was a good place to hang out. The teacher made thermite one day, and set it off in class. One student thought he could have some fun with white phosphorus, and put a piece of it in his pocket.
Our school had no hallways, only covered sidewalks that surrounded the classrooms. Another student took a mouthful of natural gas, walked outside to the windows of the classroom next door, exhaled the natural gas, and lit it, in full view of the class.
Amazingly, we all survived.
Google South Hill Virginia Crowder UFO … Describes this sixth prototype almost to a “T”.
Not centered, no problem. We’ll just point it this-a-way. I love seeing that thing flying sideways with the exhaust pointing to the side. I love it!
What I take away most from these flights so far is that the Raptor rocket engine is real, getting realer fast. Very impressive given the technology involved, as it is a SIGNIFICANT advance over everything to date.
I can not wait for the version with the real landing legs attached.
As for Kaboom-a-nite as we call it.
We used to fill 75 gallon leaf bags with Oxy/acetylene mix. Then shoot at them with bottle rockets until they exploded.
Or we would make tennis ball cannons and shoot flaming tennis balls at each other. Catching them with old baseball gloves.
The best thing was our parents would sit outside and watch us do this.
How soon until we can launch the S.S. Botony Bay with all those Antifa and BLM in suspended Animation?

Done that. The things we laugh about, now. Life in the Nanny State isn’t nearly as much fun, is it?
The things our children and grandchildren will miss.
