It’s worth remembering that while it’s really cool to have a lot of fire at the flamey end, the less thrust starship generates while doing the same job, the better!

Are we seeing SN8 having asymmetric raceways? It would make sense if the aerodynamic surfaces needed to be very different on windward and leeward sides, but it’ll make for some interesting issues with keeping the pointy end upwards during launch. I guess the space shuttle had to solve issues like that too, so it can’t be an unsolvable problem.
They've laid in some serious electrical service / wiring to the gas well area. A lot. Like, substation scale service. Thoughts: - Substation- Large scale generator (like, larger than what's at the solar field)- Control Center- Charging station for all of Nomadd and Mary's livestreaming gadgets

I guess the space shuttle had to solve issues like that too, so it can’t be an unsolvable problem.That's actually not much of a problem at all. Any rocket guidance system has to deal with asymmetric forces all the time; first the wind, then gravity as soon as you turn downrange.It's called a closed-loop control system. In simple terms, he computer knows where the rocket should be pointing and (from sensor inputs) where it actually is pointing...

Hello everyone. I would like to say thank you to Mary and NSF for the amazing coverage of Starship. I got to show my mom and pop I am working on these vehicles. I told them to look at a certain minute in a recent video. I was wearing something my mom knows is mine. She said she was very proud of me, for the first time in many years. I will also get to show my daughter who is not old enough to understand yet that her pop works on these vehicles from the early days, vehicles that will take people to the Moon and Mars. When they are, and they will, I can show that minute of that video and point myself out. It has made me so emotional I wanted to say thank you here. Mary, you are our documentary maker. Thank you.

I hope somebody knows where all this stuff goes. It looks like there are two 5 ring high stringered sections. Maybe for unpressurized nosecones.
