Does this mean they've abandoned Falcon Heavy? Or is this scale even bigger than that?

Hold hold hold on primary announcement net

Oh boy it's happening!

Falcon Heavy core diameter is 3.66m, same as Falcon 9 . This is 12.7m so yeah...slightly bigger

Bet they got a 30 min presentation and scheduled an hour for it because that's just how DelayX rolls

Now we know who inherited Jobs' reality distortion field.

Yeah, the whole thing looks too sci-fi to be realistic: those solar panels, the massive windows, landing on the launch pad and relaunching immediately, a single tanker to refuel... and the terraforming. There's too much artistic license in there to take it seriously.

Those 42 engines seem very close together. Definitely no room to all gimbal. So either they only gimbal the center ones (which seem to have a bit more room) or they control trajectory by throttling, which seems tricky.

I agree but it is a very pretty video which I think is the point.

I imagine the center ones would have to gimbal especially given what they show in their animation. For launch though the system is wide enough that they probably could just throttle steer which is tricky but not undoable or they might just have a couple of the engines on single direction gimbals that would angle them out to the side a bit to generate the needed torques.

I like that they used a moon gravity assist to get to mars.

That is just an image for the sake of being pretty and to make it clear that you're far away from Earth and going further. There is nearly zero reason to gravity assist off the moon since you and the moon are both in the same gravity well (earth) trying to go to something outside the gravity well (mars).

LMAO...

He seemed a bit a nervous at the beginning...

come on Elon u are wasting time...every single person watching knows the why....tell us the how and when!!!!

ok...heres the gravy

ITS launches dry

Well.... that's ambitious.

That spacecraft is pretty.  Though I think Orion shaped solar arrays would look better than those sail like things.

[RedKraken]

whats the dry mass of that booster ...400t? No 275t

[StarStreak2109]

Made from the SpaceX engineering CAD models?!!! Okay.... WOW!

Edit: 3-5 trips to refuel in orbit!

3-5 refuel missions.

[RedKraken]

3-5 tanker trips

Doesn't really mean much. Anyone with a computer can make a CAD model.

[RedKraken]

ITS needs to last 15 missions

He also said the other way. That they want it to be that shape. Anyone can made a cad model

[tater]

Yeah, that He for pressurization has been a problem  .

[RedKraken]

rcs is methalox too

[StarStreak2109]

How will they make that huge window go through max-q???

[RedKraken]

A 1000 ship fleet .... colonize mars within 100yrs.....ok (slowly backs away)

[tater]

ROMBUS, lol.

(ROMBUS was designed for 450 mt to LEO, then land booster).
