SpaceX Discussion Thread

Do we know yet what arrangement of engines that SpaceX plans to use on the Super Heavy, and what the bottom of the Super Heavy will look like? t won't have the four landing legs any more, but is it going to be a straight 9-meter diameter cylinder all the way down, or does the body flare outward at the bottom (as I have seen in some renders)?

no, as per last blueprint, is just a 9 meter wide tube

So starship style landing legs? 
Should work as with all the engines it will have an low center of mass. 

No catching it by the fins is well down the line, they are just now crowd sourcing how to do it :)

Funny you should mention that... 

 

...and this is why the future of Space needs to be commercial, and not governmental.  Government programs paved the way - but no government has ever been as flexible as a commercial operation can be.

"Needs to be a few hours at most." is "aspirational" I assume.

It's always 'aspirational', but regardless of whether that goal is technically achievable or not, the ambition of it is a big part of what keeps SpaceX moving so fast.

What's the mass of a Raptor engine? I'm sure they're planning to be able to carry spare engines for astronauts to replace on Mars if needed.

I doubt they'll bring entire spare engines along, many of the first Starships to land on Mars will probably stay there so they can just cannibalise components from them.

Ooh, yes, that's a good idea too. I dunno, though, Starship is pretty big. They might be able to fit just one, like a spare tire in a car. I'm sure they'll at least have a small stack of extra heat tiles, in case they find some broken en route to Mars.

Good thing about the stainless steel construction is that they'll be able to cannibalise literally everything. Old ships could be cut up and the material used to construct and repair buildings and vehicles. Raptors could be removed and used as spares, as I already said. There would be plenty of intact heat tiles, and they might even be able to use the tank sections as propellant storage.

They're also more than ready to embrace the failures, and in fact expects failures. Harder to swallow for governments when the opposition can throw "but the money !".

All I'm waiting for are just the free fireworks show, then after the show ends we'll have a new technology ready for use...
