Summary from my watch: - Launch roughly on time, after a scrub yesterday. (Sounds like the scrub was due to ground equipment, most notably the water system.) - Initial ascent was good, but then one engine on the booster went out. - Relight of the booster's engines after stage separation for the boost back burn failed. Engines did light again for a landing burn, but seems to have hit the water harder than expected and…

The videos were incredible. My favorite part was watching the booster flip in such clarity. Normally we don't get full view of it, let alone 4k.

It's worth remembering that, according to SpaceX's own filings, they've spent >$15 billion on the Starship program thus far with more to come. And SpaceX is burning cash still, particularly because Elon Musk bailed out his own bad decisions with Twitter and xAI with SpaceX stock, basically. Flight 12 was a relative success. Some engines failed to light but that's an unintended good test. Rockets are typically designe…

> Say F9 is $20M and Starship once it starts launching Starlink is $10M that's 150-300+ launches just to break even.

Assuming they deliver the same payload, sure, but that’s very much not the plan.

Earlier quoted context omitted.

The takeoff looked almost normal but I noticed a slight drift from vertical, likely because one of the engines was dead or dying. Overall the V3 is supposed to be an upgrade but actual progress is more or less stalling compared V2.

It is supposed to tilt away from the launch tower immediately, you can see this on previous flights. This keeps the engine plume away from the chopsticks and top of the launch tower.

Also an additional goal is to get the booster as far away from the pad as immediately possible in the event it falls back down.

Another flight with many explosions and a trivial payload. Trial and error, trial and error. At least these million monkeys have upgraded from typewriters to something more fun.

You don't see the progress between flights, do you?

Some of his employees have died in the meantime, but that's a price Elon is more than willing to pay

I'm concerned about the cracking clearly visible on the heat shield tiles. It doesn't bode well for rapid reusability.

I thought the tiles were designed for easy replacement, so not a big concern with replacing cracked ones.
