Brofessional Posted November 20, 2018 Share Posted November 20, 2018 (edited) Starship seems like kind of a dull name at first, but if you give each vehicle a unique name like the shuttles had it's pretty cool.

No idea what the last comment was about, probably just wild future speculation... I don't think this is the case here... "Super Heavy" simply means it is... well, super heavy. Quite a bit heavier than, say the (Falcon) Heavy. This tweet seems to back up the single-stick design: Yes super heavy is simply the BFS first stage or BFR Quote Link to comment Share on other sites More sharing options...

I can't wait for the usual suspect to latch onto the promise that someday a version will go to another star system. I've also seen good arguments that they might dump the pointy nose.

tater Posted November 20, 2018 Share Posted November 20, 2018 I think this is not a troll. He tends to do the stream of consciousness thing. I think they came to a realization regarding the vehicle, and they're going with it to move it left on the schedule. We know the diameter is unlikely to change for this iteration, tooling is expensive, and they have tooling (and parts). Engines have years of work, also not changing. That leaves everything else on the table. They already own a functional rocket factory, and with F9 stage 1 reuse, the booster part of that factory will be semi-idled. How to move left on the schedule, and what is counter-intuitive? Counter-intuitive? Blunt nose. I still think they might fix the fins, and put the "up" side opposite one fin, like this: Y Move left? Stage 1 is built of F9s. Not like FH, but bolted together, and landed as a unit. They can build that really soon, and they might be able to start with previously flown cores, reducing costs. Blunt nose also reduces cost, they build tanks, they build tank ends. Done. Quote Link to comment Share on other sites More sharing options...

BFBooster is a lot taller than the F9 one. This might be as non-trivial structurally as Falcon Heavy was. Quote Link to comment Share on other sites More sharing options...

So... like the first stage of the Saturn I and Saturn IB? Spoiler https://en.wikipedia.org/wiki/Saturn_I#S-I_stage Quote The propellant tanks consisted of a central Jupiter rocket tank containing LOX, surrounded by a cluster of eight Redstone rocket tanks: four painted white, containing LOX; and four painted black, containing the RP-1 fuel.

Looks like it might be able to cut it, but I suspect they had a big booster in the renderings for a good reason. The FSH version would also have a lower fuel/dry mass ratio. And it has to do a RTLS after separating from the ship. Edited November 20, 2018 by cubinator Quote Link to comment Share on other sites More sharing options...

BTW, this is what I was thinking in terms of FSH/BFS: Reminds me of an passenger shuttle I use in KSP, it uses 7 large SRB as first stage then the shuttle with rear heat shield, fuel, engines an MK3 passenger compartment. But no they will not use something like that. Quote Link to comment Share on other sites More sharing options...
Elthy Posted November 20, 2018 Share Posted November 20, 2018 I doubt Elon will want to go with clustering again after the huge mess with the Falcon Heavy. Redesigning the core again for this task is propably as hard as building a new rocket, especially if you allready have tooling/engines for the large version. Maybe the will make the BFS land sideways somehow, that way they dont need the risky turn during reentry and have an easier way to disembark.

You're saying that you aren't sure about the changes because they haven't been built yet and, more importantly, change rapidly, right?

Until they freeze the design, I'm not even bothering to pay attention to the latest idea Elon has had. Hopefully, they opt to make something that's actually possible, instead of blindly chasing Elon's latest notion. Quote Link to comment Share on other sites More sharing options...
