The FAA recently updated this page as part of the new Environmental Assessment at Boca Chica which is required before SpaceX can be approved for orbital flights.

Their current approval is good for testing (vertical) flights of Starship and Superheavy, but does not currently permit orbital flight from Boca Chica as I understand it.

They are currently in a public comment period thru Jan 22.

Why the desalination plant?

Is there not piped water? Is it just another eco friendly sounding thing to put in the plan? Is it to hedge against newspaper headlines saying how much water spacex is wasting?

Desalination has to be more expensive than piped water (both financially and environmentally).

Boca Chica is a relatively isolated location wedged between the Gulf of Mexico and Mexico itself. Texas is a big place, and if you want fresh water you might just have to make it yourself.

Take a gander at Google earth, Boca Chica is far enough away from Brownsville that I doubt it has municipal water or would ever be serviced. Salt water and steel don’t mix well so I’d assume they want to stop trucking it in.

They have plans for building launch sites offshore. They're presumably exercising their muscles on as many of the end-game problems as they can.

The bubble wall tech will probably be a big enough problem to sort out once they try to build them.

It may be that they need too much for the local water company.

During launches, they need to spray water- a lot of it. Using salt water would probably be problematic. Lots of residue left over.

> The fully integrated Starship/Super Heavy launch vehicle will be approximately 400 feet tall and 30 feet in diameter.

For reference, the Saturn V rocket from the Apollo program was 363 feet tall. It was 33 ft wide at the first stage, while Starship is 30 ft wide all the way to the top.

It's just massive. And it's fully reusable. What a game changer.

SpaceX's assembly and testing cadence is quite amazing. They're already putting together pieces of SN17!

Serious cadence.
