Earlier quoted context omitted.

Much of Texas has brackish water when pumped from wells. It’s the reason a lot of desal tech originated there, FL and CA.

Additionally, Texas also has very few natural lakes and reservoirs.

Specifacally, only one lake is natural. The rest of them are manmade.

> 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.

This factoid [1] may soon need an update. [1]: https://www.guinnessworldrecords.com/world-records/largest-r... "Largest rocket"

Nice use of "factoid". Most people use this world incorrectly.

I'm really interested in seeing how it will perform its "belly flop" landing. Seems like a high risk maneuver https://www.youtube.com/watch?v=DdTYMry7fq0#t=1m17s

My guess would be it will still have a launch escape system for the passenger variant. So if the belly flop doesn't look right or if it doesn't stick the landing it just ejects the crew.

I find it a little weird that FAA handles space stuff. I think they should coordinate, but basically they are for aircraft. There should be a FSA that handles space traffic.

I'm sure SpaceX would be interested in your plan to get to space without passing through FAA regulated airspace.

An interesting thing here is SpaceX are building TWO launchpads. Which will definitely help prevent delays if an when there is an AMOS-6 [1] or Orb-3 [2] type explosion that destroys the launchpad. It may also help for rapidly testing orbital refueling in 2022, though the plan is to do orbital refueling with 1 launch pad, 1 Super Heavy and 2 Starships (1 standard, 1 refueler) with 1 hour turnaround times between laun…

They could also do two launches within a single launch window.

They also want to be able to refuel super heavy in orbit off another super heavy.

There's really just not enough commercial space traffic yet to warrant its own agency. I think that's becoming less true with LEO megaconstellations of satellites, but it's still probably too low volume for now to warrant an entirely separate federal agency.

Given the nature of space, what we probably need is an international space agency to handle regulation.

Might be hard getting USA, China, Russia and the EU on the same page though.

considering this is over 50 years after Saturn V, I don't feel this is such a huge feat.

A launch escape system is not necessarily safer than without one.

They could launch from outside America.

They've already said they plan to launch from floating platforms in the ocean...

2001 predicted we'd be permanently living in the moon with orbital space hotels two decades ago, and no one ever thought they were being unreasonable if we kept the same momentum as the 60s, so yes it's sad. But we have to take things for what they are and what spacex is doing is definitely progress.
