Rick Tumlinson thinks it needs more vision. I agree.

It wasn’t an accident; Google’s corporate culture is badly broken.
Search-Engine Mystery
I’ve been doing searches for a couple months on “mann steyn simberg trial,” but very little new shows up over time, and it mostly links to articles supportive of Mann. As a result, I had no idea that Just The News had been (like almost no other media outlet) doing good reporting on it since the trial began. Does anyone else want to try?
BS From The FAA
They are grounding Starship until they are satisfied with the mishap investigation.
They have no legal basis for doing this. There was nothing about that flight that endangered the public, which is the only thing they should be concerned about. They do not do mission assurance, and SpaceX shouldn’t have to wait for them to reissue the license to try again.

How thirteen different news outlets covered the SpaceX flight.
Doubling Computer Speed
…at half the power, using existing hardware. This seems like a big deal, but I suspect it means rewriting a lot of code. I’m wondering if AI could help with the code rewrite?

Launch time has slipped, now in a little over half an hour.

[Post-flight update]
My immediate thoughts: Booster didn’t survive, but it did seem to make it to the ocean intact, so that’s a step forward. They’ll probably figure out why they didn’t get a proper relight of the center Raptors, but that’s not important to a customer, any more than whether a Falcon booster comes home does.
As for Starship, they can clearly get into orbit, and open the payload bay doors, which is necessary to deploy a payload. But they didn’t demonstrate on-orbit engine relight, and until they do that, the ship can’t be considered operational, because it has to be able to deorbit, even if it can’t survive entry, so it doesn’t become a navigation hazard. They also seem to have an issue with attitude control, unless they planned that continual roll during coast (and that may have contributed to the failed entry as well), and absent that, they can’t deploy satellites. Until they solve those two issues, they can’t consider it operational. But I think that this was a huge step forward, and after another test in which they do relight the engines on orbit, and can demonstrate attitude control, they can start deploying satellites (likely Starlink initially).

Here‘s Marina Koren’s take.
[Update a while later]
OK, technically, they didn’t make orbit, but they certainly achieved orbital speed (as planned). They didn’t circularize because they didn’t intend to.
[Friday-morning update]
Here‘s Eric Berger’s take. He says that the roll was not planned, and it was why they didn’t attempt the relight.

I never met him, but regularly interacted with him on Twitter. I just learned that he passed last year. He was a very interesting guy.

Here‘s the obit. Hadn’t known he was an MIT grad.
A Fusion Breakthrough?
Maybe. It kind of reminds me of how modern fighters can be unstable (to give them better performance) through the use of smart avionics.
