…is an indictment of our times.
A large part of NASA’s problem is that dishonesty is often rewarded, particularly when testifying to Congress.

SpaceX Launch Costs
Ozan runs some numbers.
After the Starship $300/kg price floor nonsense made the rounds, the ones who shared the studies started saying there isn't a better model out there to look at. I'd be willing to bet whatever @mach33 has put out is way better, but I've always run my own numbers on this stuff…

I don’t understand, though, how you get two flights per pad per day into SSO, at least not if you want the SSO on the terminator, which is where everyone claims to want to be, for continuous sunlight.

The PhD Experts
Well, this certainly kicked off a lively discussion (full of nonsense in replies):
Your occasional reminder that physics PhDs are not engineers. The physics PhDs told us that we couldn't do missile defense. https://t.co/ra7Ybd82G0

The Business Of American AI
Is it sustainable?
“…the US AI companies remind me a lot of 1970s era Detroit with the Chinese companies today playing the role of Toyota, Honda and so on. At least Detroit had mostly depreciated the majority of its factories and the like and wasn’t in the middle of building massive new ones.”
Not clear to me what this implies for the viability of space data centers.
Starlink Out Of The Cape
Why is SpaceX really ending those flights?
I agree that Elon wants to see more competition in the industry, and it’s time for the other companies to step up. A prevailing theme of Smallsat this week was the seeming dearth of launch opportunities. If I get my new venture off the ground, it will be a personal concern to me as well.
Brightline
The slow-motion trainwreck that anyone paying attention saw coming.
We rode it last year from Miami to Orlando. It was fine, but hardly high speed. Driving through Vegas yesterday on our way back home from Park City, we saw no signs of construction of the planned HSR from there to Victorville, let alone Rancho Cucamunga. They clearly don’t have the money.
And yes, this:
High-speed rail is catnip to politicians. Except it doesn’t work in America. Not only do we drive, but we take airplanes. As I said in March, much better to build more lanes on an expressway.
I’ve been saying for years that widening I-5 between the Grapevine and i-680 (as Pat Brown always intended) would be a vastly better investment for ground transportation between LA and SF than rail. The two new lanes could be charging lanes for fast electric FSD cars.
