SpaceX (general discussion)

Musk is Sergey Korolev, and he knows it
Korolev died on January 14, 1966, and Musk was born on June 28, 1971

And exactly what significance do you attribute to those two random dates? But I understand that you are probably just mindlessly following Putin's inane propaganda. Or do you really believe in reincarnation, and if so, why are you even in this science and technology based forum???

Rationally, logically and methodically explain your relevant knowledge then, please. Mind you, this is an *apolitical* science, engineering, and technology focused forum, without any ideological bent other than getting to the core objective matter at hand. Remember, sine īrā et studiō.

Thank you for your valiant effort, but I'm really more of a white wine kind of guy - reds are just way too punchy in the palate for me. And from a pure engineering point of view, fermenting grapes with utterly superfluous skins and seeds for red wines, as opposed to removing any extraneous matter, as is customarily done for white wines, to me is just lazy and utterly barbaric pseudo wine-making and trying to pass off a process bug as a feature, instead of extracting this vile detritus in the first place and reducing local entropy. But also, for a general discussion of SpaceX, we seem to have drifted *well* off topic - perhaps we should focus on various Cannabis strains instead?

i'm 3 day away and find this thread like this...
...we are not Wine discussion form !

now new pic from flame trench
what wonders me ist the middle section how is that cooled during launch ?

There would probably be a collector in the middle.
All pipes are also not finished as shown here. They need connections from on to another.
I would say that it´s a biphasic cooling system, the water is heated under pressure to generate steam. This increases the cooling capacity.
What they do with the steam would be interesting to know (reinject within the rocket plume?)

Of course, if Radian is lucky enough to get to LEO, it won’t get as hot as a Starship returning from Mars.

I think they also have more lift/mass, and so can fly a more shallow re-entry. The sandwich of materials they are using is not notable for how much heat it can withstand, but (supposedly) for how cheap and durable it is. The problem facing a re-entering Starship, even from LEO, is probably significantly harder.
 
I saw something of interest from a YouTube channel called Xandros (Nuclear Pogo Stick).

Now the subject of the video was pulse Orion, but at the 3:19 minute mark a claim was made that Falcon 9 had a much tougher ride that R-7 Soyuz.

Now, maybe this video was tainted by some anti-Elon sentiment, but if it is true--might that means FH really is no less harsh than SLS?

Could R-7's use of cones (triangles again:)
might there be something to the allegations?

Lastly--has any LV been designed around the idea of a smooth ride?
 
Marcus is always so pleasant and positive.

SuperHeavy seems to have less problems during static tests than Starship…might a higher number of engines have less problems with vibrations than a fewer number more widely spaced?
 
SpaceX made since June 4, 2010 to May 4, 2025
470 launches of the Falcon 9 rocket.
now with 13 to 14 launches per month and turn around time of 48 hours for Launch pads.

If this serve as template for Starship
with 14 launches per month, that's 2100 metric tons in low earth orbit !
will mostly Starlinks and propellant for interplanetary Starships
