SpaceX's SN9 lining up for a 10km altitude lift off and return - I assume they are hoping for some time today...

Lift off was at 2:24CST if you want to watch it.

Wonder if the FAA are happy?

Not happy, but maybe feeling a bit vindicated.

And from further down that thread here’s a side by side with the last attempt. This latest one was worse.

Why do they call it a starship when it only goes to low Earth orbit*?

This probably bugs me more than it should.


*when it doesn't go boom.

My understanding is that It's designed to go op top of a Falcon SuperHeavy rocket so that it will go beyond Low Earth Orbit and ultimately to Mars and beyond.
The use of Methane burning engines is (in principle) so that it can land in one piece on Mars - create replacement methane using Solar Panels and then return from Mars to Earth without having to take stupid amounts of fuel with it.

Still not a starship unless it goes to Alpha Centauri or further [/pedantry]

I don't think going into low Earth orbit should be called "space exploration" either.

I'll accept the Sun, and maybe Jupiter. Although that's more of a "failed-starship", which is more in keeping with Musk's capabilities.

When was the last time you saw a Ford Fiesta host a party, or a Ford Focus concentrate on anything?

They're model names not vehicle types. The motoring equivalent of calling musk's rockets "starships" would be calling a mini minor a luxury coach.

Starship is also a model name.

People seem to be annoyed at the star bit being wrong, rather than the ship bit.

Spacecraft get called ships by simple analogy. Although since they are more like submarines than surface vessels in their self-dependency requirements for housing crew, maybe they should be called starboats.

I once watched a conspiracy theory "documentary" that had space submarines in it. And that wasn't the most bonkers bit.

Didn't involve the "Dean Drive" by any chance, did it?

I'm afraid I can't remember. Think there was some sort of anti gravity thing given to the Nazis by the reptilians.

But spcecraft don't (necessarily) go under water, so shouldn't they be supermarines?

Plus, spacecraft and submarines are fundamentally different; spacecraft keep a livable atmosphere inside when it's a vacuum outside, whilst submarines keep a livable atmosphere inside when there's several atmospheres of pressure outside.
