Starting with the basics, from the center of SASSY, the hub is 30m long, 9m wide (longest outside diameter), 7.794 (shortest outside diameter), with 15cm panels.
Anyone who wants to extrapolate or work on this is welcome. Expecially if you're an AutoCAD guy
Oh man.

I feel like nobody listens to me and then takes years to get around to realizing the reality of things. Or maybe they do and just wait to make it look original.
MOONPODS.
This was the best question of the press event, and beyond the advice to follow your passion because it may very well lead you to the Moon, I think Dayna Ise gave a great answer on a specific discipline with robotics. We want astronauts living at the Moon Base, but also want to keep the EVAs to a minimum!

As a space station guy, it was pretty interesting watching @rookisaacman pull the plug on the fantasy that if you just build a space station, people will pay $50m to go there. Maybe a few will. That's not a business. Transportation cost is higher than the station rent. By a lot.
Marginal viability at around $1m per passenger. Real viability when it gets to be more like $100k. If 1000 people are allowed to stay a week on C-SASS for $m each week, that's $50b in a year. That's nearly enough to pay for Gen 1. In one year. But.....

Just think about the fact that a senior engineer for an ostentibly gravity oriented space station company had to ask about coriolis on the internet. That's the disturbing part, not the lack of appreciation for being the only one to explain it to her.
My beef with three space station companies:
Gravitics CEO, calls me under completely dishonest pretenses for what purpose?
Axiom CFO, gets snarky with me about asking engineering questions they couldn't answer
Vast engineer, asks how coriolis works, I explain. Zero thanks.

I wonder how many Falcon 9 and Starship parts have been stolen/gone missing. Oh, like basically zero due to competence.

Battle? It's not even a kerfluffle.
The space station battle takes an intriguing turn.

One of the things to keep in mind here with prices going slightly up and not down, is that all of this "profit" is going to reinvestment and taking everything to the next level. This isn't Apple, sitting on $60B in cash. The more profit, the faster we go. Meanwhile, "iPhone 18"
SpaceX Falcon 9 pricing vs. Inflation (2021–2026) 🚀📈
Interesting article by @SciGuySpace :
•Rideshare: $5,000/kg => $7,000/kg (~40% increase)
•Dedicated Launch: ~$62M => $74M (~19% increase)
The Economics Breakdown:
Cumulative U.S. CPI inflation over this period was roughly 23%. This means Falcon 9's dedicated list prices are actually flat-to-lower in real, inflation-adjusted terms. Meanwhile, the real increase for rideshare slots is only around 17%.
Because SpaceX's internal cost for a reused Falcon 9 is estimated in the mid-teens of millions, these list prices reflect strategic demand and capacity allocation, not cost recovery. Rocket Lab bumping its upcoming Neutron price from $55M to $70M mirrors the exact same constraint.
A classic simultaneous shift in supply and demand. I tried to visualize this shift here:
