>>8449663
they already have the engines and oxy tank prototypes ready.

>there will be dildo replicas

>>8449675
nope and nope

SpaceX is trying to get people excited for space. Something that I have no problem with. I highly doubt that Musk actually thinks he can pull it off in that time, it's just a very generous estimate to keep people interested.

>>8449663
Musk has a history of promising impossible deadlines, but the thing is even if he misses the deadline, he gets shit done way ahead of any reasonable schedule, and then people give him shit for missing the deadline anyway, it's retarded.

So no prob not in 6 years, but he will build it faster then it should be possible.

NASA doesn't even have a plan ffs and they are supposed to go to mars in the 30's, he's way ahead of were they are.

i just want to see Falcon Heavy launch and land successfully sometime in the next two years.

I don't necessarily see why its impossible for them

They only need one craft and booster and tanker built for 2022

>>8449796
and they have to rebuilt the launch pad at Canaveral. because the booster needs unique pad design.

>>8449803
thats not anything that would delay launches
since it can be done in parallel with building the ITS

Question.

Just how much money Elon Musk has and how much is he gaining compared to his investment on these advances?

>>8449897
spacex alone has about 10 billion, whihc is about the aproximate cost of the ITS development

of courese they arent gonna just dump all their money in this but with some funding they can surely get it done

>>8449897

when this is a priority

>>8450116
>>8450111
The Falcon Heavy was definitely delayed in development, but it's also completely ready to go right now. The reason it isn't is because they're booked solid with Falcon 9 flights.

And I suppose "we have more payloads to launch than we do pad time" is the best kind of problem a space agency can have.

>>8450070
It's merely a schematic, to illustrate the concept

>>8450121
they have 3 used boosters that aren't booked.

>>8450183
and which can't be used for the falcon heavy, because the falcon heavy needs different boosters

>>8450221
they are literally turning two of the landed boosters into fh boosters right now, you tard

>>8450116

The high commonality between Falcon 9 and Falcon Heavy has meant both that Falcon Heavy has been largely a matter of making the choice to launch, and that it makes no sense to launch it until the bugs are worked out from Falcon 9 or they run out of waiting Falcon 9 customers.

Falcon Heavy is not a separate vehicle, but a configuration of Falcon 9, and one which costs triple the factory time but commands a price only 45% higher. It will not help them clear most of their commercial backlog, and is not the priority for their most important customers: NASA (which needs them launching Dragons on time, and wants the Crew Dragon) and the Department of Defense (which wants vertical payload integration and other preparations).

They could have foregone 2-4 Falcon 9 launches and done a Falcon Heavy launch at the end of almost any timespan in which they did 2-4 launches, but their flight rate has not been adequate to focus their efforts on it, rather than on improving their Falcon 9 flight rate. Furthermore, each time they find a reason to upgrade the Falcon 9 hardware through flight or test experience, any Falcon Heavy hardware they've built is made obsolete, and they don't want to launch it anymore.

For a recent example, recovering boosters has enabled them to discover things they should change for them to be reusable. At the same time, they've learned a way to get a little more thrust out of the engines, which will allows them more margin for reuse. The benefits for Falcon Heavy reusability are larger than for Falcon 9, so they absolutely don't want to proceed with a Falcon Heavy launch without making those upgrades.

>>8451218
>150 tonnes heavier
>still less load to LEO than Delta Heavy

>>8451218
why would they use boosters if they are designing a rocket from the ground up?

>>8450731
>reading comprehension is the ability to comprehend text
which "he" lacks and therefor "proved" no point that was made

>>8449663
Saturn V took only 5 years from finalized concept to first flight, with 1960s technology and only a few years of prior orbital spaceflight experience.

Falcon 9 and Dragon flew just four years after finalized concept, and then served as testbeds for development of the foundational technologies for ITS. Only four years after first equipping a Falcon 9 body with a throttleable engine, flyback recovery is in the early stages of practical usefulness. SpaceX moves as fast as the early space program did, because the people are working in the same spirit.

ITS isn't really more complicated than Falcon 9 with a Dragon on top. It's just bigger. In many ways, a larger rocket is easier. You can afford more elaborate surface treatments, such as anti-corrosion and insulating layers. The tank walls and fuselage are thicker and therefore simpler to fabricate and more tolerant of small flaws.

>>8451354
Parallel staging at lift-off is a very reasonable design choice. You need lots of thrust to get off the ground, then much less after you get to supersonic speed in the stratosphere, then much less again to get from low km/s speed in a vacuum to orbit.

Three-stages, with the first two operating in parallel at lift off is generally regarded as optimal for an expendable vehicle.

>>8451406
I dno't think its too reasonable from a cost point of view if you are building the rocket from the ground up.

Plus then you end up with a rocket that has no growth potential.

>>8451320
And a lot of the problems you've addressed will be resolved in two years when SpaceX has their own exclusive launch facility in Texas instead of leasing old NASA real estate, right?

>>8449663
Those are some cool dildos

>>8451578
Boosters are totally reasonable for cost. They're very common, and make the system less dry mass sensitive, which means simpler fabrication techniques can be used.

Anyway, LM5 was supposed to have a variable number of boosters, but LM7 is taking that role, so only the maxed-out version of LM5 will be used. It's like China's answer to Delta IV Heavy.

>>8451582
Not really. It's mostly about getting Falcon 9 operationally mature.

>>8451587
25 tons to LEO is quite an impressive heavy-lift rocket, it's just not in the super-heavy class.

The engine they tested had 1/3 the thrust of the full size version, and the specs they posted were "design goals" not "we have this engine ready to go"

The tank is not the full size (it is shorter) and they haven't tested shit with it, it hasn't even been loaded with subcooled oxygen yet

A lot of the changes they're making are for the sake of simplicity.

No separate upper stage and capsule. Two-fluid propulsion system (methane, oxygen) rather than 7-fluid system (RP-1, oxygen, helium, nitrogen, TEA/TEB, MMO, NTO). One engine type rather than both SuperDraco and the Merlin.

The production version of Raptor will likely be mechanically simpler than Merlin 1D. They're using fluid bearings instead of ball bearings, the full-flow staged combustion will mean no seals between lox and RP-1 being pumped on the same shaft, no separate vent for gas generator exhaust, spark ignition rather than shots of hypergolic starter fluid.

The engine count is about the only thing that would make it more complex, and that's better described as "big" than "complicated".

Reentry using a building-sized ship at 35,000mph using a tps never tested outside of LEO, laid out in an asymmetrical aerodynamically unstable shape rather than a round blunt body is "not more complicated" than falcon 9 and dragon? (this of course being only one of the multitude of problems making it substantially more difficult)

You are honestly delusional.

>>8451658
>>8451660
>>8451684
(I'm not the guy you're replying to)

"Ready" was overstating it, but what they have is a convincing proof of concept, consistent with their goal of launching the complete system in 6 years.

Nobody really disputes that they can scale Raptor up 3 times. The claims about the problems they'd have with Raptor were all about things like the high pressure and oxygen-rich turbine. And if they can build tanks of that diameter, they can build them longer.

Raptor and the tanks should both be good enough to start atmospheric/suborbital "spaceship" test flights in 2 or 3 years.

>>8451693
>aerodynamically unstable shape
It's another simple blunt body shape, just cylindrical rather than spherical (which has also been done). I doubt very much it's going to be aerodynamically unstable when they're done with it (Musk has stated they're going to add some aerodynamic features such as actuated control surfaces). If you haven't noticed, they've got some people who are pretty good at fluid mechanics at SpaceX.

>>8451740
right, but how does that make any of it simpler than falcon 9?

>>8451743
Not overall simpler than Falcon 9, just "isn't really more complicated than Falcon 9 with a Dragon on top".

As for the parts of it that are simpler than Falcon 9, I already gave some examples.

>>8449663
>gradual infiltration

https://en.wikipedia.org/wiki/Interplanetary_Transport_System#Fabrication_cost_projections

>Tanker $130 million

So: around eight times as much as comparable Falcon 9/Dragon stuff.

>>8451984
>https://en.wikipedia.org/wiki/Interplanetary_Transport_System#Fabrication_cost_projections
I would be reticent to believe the number of relaunches they expect. Seems like the stresses on the materials would illuminate even the smallest imprecision in manufacturing over time. I can't imagine they would be giving it detailed and thorough QA after each use, if they expect rapid turn around.

>>8452004
I think that's their end goal, not their initial expectation.

For their first unmanned ITS Mars landing, they'll probably be ecstatic if the booster and tanker last long enough launch and fuel the first spaceship, and that ship lands on Mars once.

>>8452004
Bear in mind that airliners which routinely fly in rough weather and through turbulence and go to a low-pressure environment can have lives of over 100,000 cycles.

1,000 cycles might seem very long for a rocket, but it's very short for an aircraft.

>>8452082
they get 25 tons to LEO by taking off the second stage
2nd stage is for sending shit to GTO

>>8452084
they can put up 25 with the version with the second stage, but it's just a waste of a stage

>>8451390
>Saturn V took only 5 years from finalized concept to first flight, with 1960s technology and only a few years of prior orbital spaceflight experience

>>8452190
Saturn V cost about $40 billion total ($6 billion at the time), including 13 launches. A modest part of the $180 billion (25 at the time) Apollo program.

SpaceX is estimating about a $10 billion development cost.

That's a fairly small factor of improvement when you consider that there's been half a century of technological progress, and the difference between public and private efficiency.

thats like comparing a bike to.. well, the saturn rocket

a ginormous craft, with mroe than two digits of meters of width. that has to reach orbital heights, exploding the fuels, corrode trough the van allen belt, and all that without recylcing the engine pumps??? maybe possible one time

Not in rocketry. Most tech progress in the last 50 years has been in computers, there's no Moore's Law for chemical rockets.

>>8453794

*IF* they deliver the ITS for approximately the same price or slightly lower than the Saturn V it's still a feat because the ITS is a much more capable rocket than the Saturn V. It's like if you managed to build a 747 for the same price as a Cessna.

>>8451406
If they're operating in parallel, they really don't count as separate stages.

>>8454071
Kill yourself.

>>8454079
In what way are they separate stages? Would you consider the Space Shuttle SRBs to count as two stages because they're physically separate boosters?

>>8454067
There won't be $30 billion for ITS development. $10 billion is what they've said.

Reason it would be comparable is that they need similar-scale facilities. Reasons it would be cheaper are that now they can do things with much less labor, and this isn't a government project.

>>8454071
Parallel staging is still staging because the boosters drop off first, while the core keeps going.

>>8454084
The SRBs are a stage (boost stage), and the orbiter is a stage (sustainer).

>>8454088
>There won't be $30 billion for ITS development. $10 billion is what they've said.
I'm not casting aspersions on SpaceX by saying I don't believe them.

>>8454098
I'm just saying they won't get the money to cost as much as Saturn V. They'll make it work with less, or fail.
