Pretty cool. I'm assuming that the "most" is by design and it wasn't just that a few of them got stuck on.

Yes, the 3 were supposed to stay on through hot staging so it wouldn't lose any momentum.

Not to get a tangent here but I watched a very interesting show the other day on the history channel that dealt with how all the big industrialists in the 30s all moved their abilities and facilities into war production.

DuPont took GM into ammunition. Chrysler into making tanks and how they were given the ford V8 to power it.

Ford was tasked with making the B-24. They initially failed because the Army Air Corps kept changing the design and every change forced the assembly line to stop and retool. So they hit on the idea of offsite engineering facilities. They built the plane in one model and got it off the assembly line. From there it flew to a facility to upgrade it to new specs. That made it work. They said that often the test flight of each new plane was its flight to the upgrade facility.

They've got a bunch of interesting series like that...the Food, the Toys, etc. Really interesting stuff. That Titans one was really cool

Absolutely.

I thought I saw at least one out after the flip that should've been on but I don't really know. Starting them up again during that flip is tough.

Yep. They are all very interesting. The real cool tidbit here was the part where Chrysler was building tanks. The original was a mess and they ended with the Sherman as a design. But Chrysler didn't have an engine to power it. They cobbled some weird Frankenstein of 5 inline 6s together but it was so big it took up the entire inside of the tank. So the War Dept convinced Ford to give Chrysler their design of the big 500 HP V8 they had and that powered the Sherman.

The booster and ship have a separate set of smaller header tanks for each propellant that remain full during flight to make engine relight less complicated but perhaps it isn't impervious to propellant sloshing issues. After all, it's possible that the header tank pressurant is autogenous gas like the main tanks which means you have to have some gas in the tanks for it to work.

I think this is the first rocket to reignite first stage engines after hot stage separation. It seems like the booster gets a serious deceleration jolt from the hot staging.

The solution might be to decrease the amount of deceleration by keeping the inner three raptors on the booster at higher throttle or keeping more engines on during hot staging to prevent or lessen the jolt.

Or perhaps we will see a change to the header tank designs to use a separate pressurant or have a number of smaller partitions. I assume SpaceX would rather go the route of changing the process and not further complicating hardware design.

Can't wait to see how this progresses.

I think "V2" Starships will be exciting to see produced. There have been hints/talk of significant revisions, of to the 'canards' (they are a bit overbuilt for what is needed), heat shield, cargo bay structure/openings (plan for something like the pez dispenser), and plausible shifts in how the plumbing etc. work/are built.

Excited to see what’s new with the next generation! Would be awesome to see 9 engine ships soon.

Guessing tanker variants might make an appearance soon as well?

I am guessing only two of those 4 will actually fly.

Also, some surprising images/data on very early galaxies has come out from Webb (and I think Euclid?) telescopes.

A philosophical discussion of Musk's interplanetary goals for human life.

Quote:

---

Colonization for Consciousness's Sake
Musk has given a compelling philosophical defense of multiplanetary colonization. In an interview with Google co-founder Larry Page, Musk said that "human consciousness is a precious flicker of light in the universe, and we should not let it be extinguished."

If current models of our solar system hold, then humans only have a few billion years left to prepare for the sun's death. After those short years pass, the sun will no longer sustain life on Earth. Musk wants humans to get ahead of this calamity. He's waking us all up to the idiom: "Don't put all your humans on one planet." By spreading out, we'll become extinction-proof.

Unlike many agnostic scientists, Musk regards human consciousness as something like a miracle. That has led some to describe his views as compatible with Christianity. And there's certainly good reason to defend Musk's stance, especially when prominent atheists want humans to understand their consciousness as a subjective illusion and its development as a random occurrence. Once we dive into the details, however, there's reason for skepticism.

The goal of his companies from SpaceX to Neuralink is to "expand the scope and scale of consciousness" and to help humans "become more enlightened" so they can better "understand what questions to ask." This will require both mental and spatial expansion, hence the dual concern with biotechnology and space exploration. Abstract philosophical and theological speculation cannot answer fundamental questions. We need applied science to make philosophical progress.

Consciousness, though worth preserving for its own sake, is not self-sufficient. Without technological aid, consciousness will both fail to ask the right questions and to provide for its own preservation.

Why in the hell is the FAA involved in any of this mishap investigation crap? That's like my 1 year old grandson helping me replace the engine on my car.

The FAA is convinced they own ALL airspace.

If you jump up, they think you're in their jurisdiction.

Everything is not as it seems 🪄

See that string at the bottom of this image? It’s made up of 2 baby stars spewing out almost parallel jets of gas. Astronomers used to think there was just one star, but Webb’s high-resolution view shows more to the story: https://t.co/CiWw93Sjeu pic.twitter.com/CcT0wP38CG

In the top half of the image, those bright objects are actually thought to contain two further baby stars! Webb’s infrared vision is particularly suited for studying young stars and their outflows, as infrared light can pierce through obscuring gas and dust.

Pretty cool stuff. NASA's APOTD is also of course worth following for the geeks among us.

https://apod.nasa.gov/apod/

Congress's bill that was in place during Obama's regime that defined the FAA's jurisdiction explicitly said the FAA had no authority over civilian hobbyist aircraft (aka RC planes and quadcopters). The FAA ignored that and took control over all hobbyist aircraft from a millimeter above your grass on up.

They're another one of those agencies who gets to do whatever they want.

These high energy astronomical events are mind blowing. If you haven't looked into GRBs (Gamma Ray Bursts) you should. The numbers involved will make your head spin.

I am not a huge fan of the FAA (I work with them often, specifically on UAS), but could you point out this "Congress bill" that said the FAA explicitly had no authority over "civilian hobbyist aircraft".

Send it via PM so we don't clog up this thread.

I remember an interview when asked about all the work that went into trying to land a booster, which at the time was thought to be impossible, Elon said, "If someone was dropping $10 million out of the sky wouldn't you try to catch it?"

Say it costs $2,000,000 to catch and refurbish for flight (I bet it's 1 million or less) so 250 catches at 8 million saved vs new and that's conservatively $2 BILLION saved by SpaceX.
