Yup and watching Gumby's youTube, in flight looked like things flying off before the circular transition was supposed to happen..

SpaceX confirms it triggered flight termination system. https://abcnews.go.com/Technology/l...light-termination-system-98734245?id=98720716
Some rumors of lots of damage around the concrete launch pad. A few cars left behind near the launch facility with remote cameras got hit by flying debris.
Have to say I’m glad we missed the rain of sand. Looks like Port Isabel got a good dose of it too.
Look forward to more in depth reporting, hopefully.

That was truly entertaining. Thanks.

OK, thanks, I watched the Everyday Astronaut footage and finally figured out they were in Port Isabel where the rain of sand occurred. They had a rather nasty looking cloud heading their way. Fortunately South Padre did not get that.

Let’s not forget the Juice mission which is on its way to Jupiter and vicinity. You gotta love those gravity assist flight paths. [emoji846]
“ESA’s Juice mission is on its way to Jupiter’s icy moons. The spacecraft took off from French Guiana on April 14, beginning an eight-year journey to Jupiter, where it will study the moons Europa, Callisto, and Ganymede. En route, the spacecraft will perform the first-ever Earth-Moon dual gravity assist flybys in August 2024, followed by a Venus flyby and then two more Earth flybys before reaching Jupiter in 2031.”

I wonder if the number of folks questioning Musk's over-personal involvement with Twitter etc is beginning to increase?
Taken in context, this entire event has a bit too much marketing context - especially given the dollar value.

What? This is business as usual for SpaceX.

Well, sure it is.
My point relates to Musk's lack of involvement - except as occasional head marketer. And, the raw amount of dollars - the loss of which could relate back to Musk's lack of involvement?

Musk has a very good person running SpaceX as has been true for many many years. These are expensive test flight projects - again business as usual as you can’t go commercial without getting through the test and redesign phases.

They also have someone on the payroll who is top notch at marketing speak.

Perhaps biz as usual - a few hundred million here and there? Tax dollars or his personal fortune or combo?
One would need to really believe SX's equipment will make a difference in raw cost at some point - or, that it is necessary to have so many large delivery platform companies - or, that there is a technical path to get people to Mars (and back).
This has always been a good discussion - but, it is not based on personality or magic.

The main reason we have to use gravity assist flight paths is to conserve fuel - better to allocate the mass toward instruments than fuel.
Now, when Starship become operational and has proven itself, you can imagine that we’ll be able to not only increase the size of the science payload of these probes, but also have much more fuel too. So it should be able to reach the outer planets much more expeditiously.

Wasn’t really unexpected as SpaceX confirmed they triggered the explosions of both craft after the separation failed. The broadcast anchors didn’t know that at the time, of course. I hear that term more as tongue-in-cheek engineering speak that has been used many times before.

I’m trying, but really don’t understand what point you’re making. Did someone claim rocket launching was based on magic?

The magic part is imagining going to Mars and coming back ... or, perhaps the sleight of hand involved with using massive amounts of government money while marketing capitalistic space flight.
Musk is very good at marketing and twisting things ... and his vision is so enticing.

Here is a great analysis of the flight, and it explains a whole lot. Well worth the watch.
What I noticed as it went through the flight a second time, was the velocity and altitude at the last part of the flight.
I reached a maximum altitude of 39 km, and then while it was oscillating and failing to separate it got all the way back down to 29 km.

Yep, "rapid unschedules disassembly" has been around for a while, and SpaceX has used it in the past:

From a blog site called Tesmanian:
https://www.tesmanian.com/blogs/tesmanian-blog/spaces-2
“Musk revealed that SpaceX did not ignite all 33 Raptor V2 engines on the booster during Starship’s 4/20 launch attempt –“There were 3 engines that we chose not to start,” he said, adding that 30 engines, “is the minimum number of engines” needed for lift off. These engines “didn't explode,” but were just not “healthy enough to bring them to full thrust so they were shut down,” he said during the Twitter Spaces chat. He said that at around 27 seconds into the flight SpaceX lost communications due to “some kind of energy event” and “some kind of explosion happened to knock out the heat shields of [Raptor] engines 17, 18, 19, or 20.” Musk said that the Super Heavy rocket kept going through T+62 seconds with the engines continuing to run then lost thrust vector control at T+85 seconds.”
““...From a pad standpoint, we are probably ready to launch in 6 to 8 weeks,” he said. “The longest item on that is probably requalification of the Flight Termination System [...] it took way too long to rupture the tanks,” he shared it took around 40 seconds and that it should have exploded quicker to terminate the flight. “

I'll wait for independent confirmation on anything coming from Musk.

I mean, it's not like he started a rocket company or anything, so I can see why you exercise caution...

There used to be a dead horse being beaten emoji somewhere on this site. Just assume I found and used it.
Musk can be cagey sometimes...
I get that he's under no obligation to tell us all the details. I get that most people would tune out a long, boring explanation anyway. That doesn't stop me from wanting to know. A cottage industry has developed, watching, listening to, spying on SpaceX and Musk and interpreting the results for space geeks on YouTube. So different from the early NASA days when everyone was interested by every detail. Oh well.
So which was it? Did they choose not to start them, or did they shut the engines down because they didn't develop full thrust?
