Starship still has a MASSIVE prop issue that is holding it back at the moment, it in terms of launch cadence. Nice tool though!

  Pipeline is getting built.

  ASU under construction to supply LOX and Nitrogen. CH4 pipeline being laid. Have no fear, these folks have a vague idea of what they're doing.

I’m getting a security warning and blockage when trying to visit that page. But my iPhone is managed by my corp 🤷‍♂️

I've been playing around this for a bit, it's really nifty. , by end of next year it should be capable of surpassing F9 in flight frequency and dwarfing it in payload capability.

  There are also limitations on airspace closures. You really need to be somewhere where you can shut down the airspace on launch and recovery corridors pretty much permanently. Florida is not good on that, Boca Chica a bit better, but still too many flights. Louisiana might be OK for SSO, but frankly they need sea platforms with their own methane and LOX production.

  Come on man. You don’t actually think 13 flights a month by next year is “conservative,” do you?

Seems a bit useless atm, other than for making up random aspirational numbers and wowing at the result. We have no idea what ANY of these values are currently or will be in the near future.

  Yeah, I think it’s useful for just informing discussions about how the ramp up might go. There’s been a lot of chat since flight 13 about the heat shield, and how useful starship will be if they have to replace the tiles after every flight. This tool lets us play around with numbers. Like if every ship takes 2 months to refurbish, how many ships do they need to still hit 100 flights per year, etc.
