damn all this time I've read and heard about this guy yet never saw him speak live and he turns out to have the speech quality equal to mine when I gave an autistic speech in middle school about video games and stuttered my way through it. Kinda feel bad for him. Can't help but have a good laff about it though.

It's less that Elon invented anything particularly extraordinary - it is simply impressive that he is a successful, multidisciplinary engineer that oversees a lot of the production and design himself, and he seems genuinely interested in using those skills to do all the cool shit that people want to see happen.

>>9198106
this wasn't the major point of the keynote

>>9198103
SpaceX are designing a completely new platform that will render their F9/FH systems obsolete. It's called the BFR. It's almost fully reusable so even though it has a higher payload than saturn V, it costs less over time because you reuse essentially the entire system every launch. you don't have the boosters / main rocket detaching and asploding in LEO every time.

He outlined the method for Mars - that there's going to be a secondary launch in orbit by launching a BFR tanker into orbit and refuelling in orbit, and then undertaking the trip to Mars.

The timeline for the Mars mission is that in 2022 they will land cargo and preliminary shit like supplies. 2024 will see the first ever manned Mars mission, and their jobs will be to establish the groundwork for future settlement and habilitation.

He also went real in depth into the guts of the BFR, a moon base and some other shit. Honestly just skip through it on YT and it will explain it well.

>>9197980
This was in South Africa.

Pretty sure he has some non-mainstream views on race.

>>9198106
I think this is really designed to get the military's attention. The US military currently has a major hardon for rapid global force projection, and the ability to land hardware and troops anywhere on the globe in a matter of minutes probably looks very attractive.

>>9198126
That is extremely clever way of getting funding.

compared to mars.....
It's a shorter trip, so perhaps ~5x as many passengers in the same volume (i.e. 500 total; cf. a380 which seats 850). It takes five (?) orbital refuel trips for the martian journey, but we'd need none of those. Depending on how much less than a full tank the passenger vehicle needs (payload could be smaller; the ship would also not reach fully orbital velocity), the fuel cost would be between 1/5 and 1/10 the Mars fuel cost.
So that would bring the cost down to between $10 and $20k/ticket, within reach of business travellers.
If maximum the number of flight cycles per vehicle is greater for Earth-to-Earth trips than for Mars, then that could further reduce the ticket cost. It's unclear to me which direction that number would go-- Earth's atmosphere is much thicker on re-entry, though the velocities will be much lower than an interplanetary re-entry. Since aerodynamic drag goes as the cube of velocity but only linearly with density, I'm guessing the speed would matter far more. That would imply much better lifetime on Earth.
So if the E2E fuselage gets only 2x as many flight cycles as a Mars trip, that could bring down the per-seat cost to $5k-- now getting close to the cost of an ordinary international ticket. Of course this is all assuming that Musk's baseline of $500k to Mars is reasonable. Would be curious to hear from some rocket engineers about these guesses at the numbers/efficiency.

>>9198126
A big rocket landing upright in a warzone sounds like a huge target. Then you have to get down from several hundred feet.

>>9198113
>kill off long distance air travel by flying anywhere on Earth in 30 minutes or less
I don't think Boeing and Airbus will take this one without throwing a shitfit, If anything they'll ally to tear down the project.

>>9198094

Lockheed's presentation was this morning and it was pathetic, I was there.

Corporate cliches and no hard numbers. Not even a mention of how they're going to get their lander vehicle into orbit, which is clearly too bit to get launched on the SLS.

its probably just the initial settlement. building underground will come later.

>>9198160
He's the public image of the company. It wouldn't be the same if he had someone else do the presentation.

The fact that he's passionate enough about the projects to come out and give such talks despite his apparent anxiety over public speaking is worthy of some respect.
Since the event was in Australia there's a fair chance he was jetlagged as well.

after reading more comments, it seems like people are under the assumption that F9 production is going to end soon. i figured that it wont end for another 10 years. who is right?

>>9198170
>after reading more comments, it seems like people are under the assumption that F9 production is going to end soon. i figured that it wont end for another 10 years. who is right?

It'll probably draw down over approximately ten+ years, I agree. Falcon 9s will be needed to accommodate schedule slippage, new customers, and the tooling for the first stages and second stages is mostly the same. A brand new second stage will still be required for every launch.

>>9198137
>Not even a mention of how they're going to get their lander vehicle into orbit, which is clearly too bit to get launched on the SLS.
The Lockheed lander isn't too big to launch on SLS. Only 30 tonnes dry mass (with 80 tonnes prop capacity). It's meant to be fuelled in space. Basically, it's an Orion capsule strapped to an ACES, with an aeroshell. It should be able to serve as an upper stage to get itself into space. They can probably launch it to LEO on an Atlas V or Vulcan. Then it's supposed to get pushed out to Mars by this big multi-launch assembled "Base Camp".

BIG
FUCKEN
ROCKET

>>9198174
it reminds me of aircraft production...the aircraft are built over a number of years then the production facility changes to build a new aircraft. at that point the old aircraft can no longer be built, only the new one.

How safe and reliable is orbital refueling? I can imagine them being able to launch the BFR succesfully, but then refueling it 4 times in orbit? Seems like a million things could go wrong there.

>>9198170
>>9198174
Elon basically announced that they're shutting down the F9 factory to convert to BFR production once they have enough stock to keep flying through the downtime.

As soon as the BFR is working, it will make absolutely zero sense to fly F9. One BFR can fly a hundred Earth-orbit missions, and do anything F9 or FH could do, and much more.

If they can make their 2022 Mars launch, they're going to discontinue F9 some time before that.

>>9198201
>If they can make their 2022 Mars launch, they're going to discontinue F9 some time before that.

I don't think SpaceX will discontinue Falcon 9 until they have their customer's trust to do so.

so how much it cost?

>>9198205
>so how much it cost?

The estimated development cost I've seen floating around is $10 billion.

>>9198201
no he said they will still have falcon 9/heavy available for customers who dont feel comfortable with the BFR. after a few years they will drop older rockets and you either deal with BFR or find someone else.

>>9198148
Why doesn't he just use nuclear for Mars?
Considering you only get a third of the solar energy on Mars you'd need an insane amount of panels for a colony they will inherently need to be a very high energy settlement since they will have to make almost everything they need on the planet.

>>9198222
>Why doesn't he just use nuclear for Mars?

They're trying. They don't have access to nuclear materials yet.

Elon comfirmed for dicklet desu

Is Virgin Galactic already done? Who would fly their ships if SpaceX can use the BFR for around the world trips.

>>9198282
Was refueling in orbit part of your plan?

>>9198284
>spacex went from testing the grasshopper to a reusable orbital rocket in like 15 years

Grasshopper first flew in September 2012 and the first Falcon 9 landed in December 2015. They did it in three years.

>>9197914
All great scientists/engineers were autistic to a degree.

>>9198249

>>Shotwell on @SpaceX work on nuclear propulsion: "We're actually trying to get hold of some nuclear material - it's hard, by the way"

They must not want to be too open about nuclear then because there's plenty of ways to test nuclear power without nuclear fuel. (pic related) Though it is good to hear they haven't completely shunned it. Maybe Elon is keeping hush hush so as not to upset his hippie supporters.

here's what i don't get: will humans stay in mars or come back to earth?

i had hoped they show more hardware and stuff and why do they want to stop making falcon9

>>9198330
Because BFT will be fully re-usable and can do everything the Falcon 9 can do but better.

>>9198326

Elon has openly discussed the possible benefits of nuking the south pole of Mars in order to kick up dust, melt ice, and develop its atmosphere.

You must be thinking of somebody else.

>>9198342

They will stay on Earth, senpai.

>>9198342
>okay, just to make sure, the whole point of this isn't to have a humanless earth, right? will they force people to go to mars?

The point is so human beings, as a species, will live on both Earth and Mars, and hopefully other space habitats in the near future.

>>9198329
Mars is a launching platform. If Mars become successful, they can launch to other planatery bodies in the solar system.

With luck/hard research/economy, we'll have better propulsion system in the next 50 years that will carry people over faster/longer distances.

>>9197916
because the earth is overrun with niggers my hooked nosed friend

>>9198135
They'd probably land these in predetermined landing sites which are either secured or at least not the site of an active firefight.
With a low-tech enemy unable to detect launches and rockets in space, there will only be 2-3 minutes' notice between the rocket becoming obvious and actually landing. That leaves plenty of time for soldiers to hop off the rocket and secure a perimeter before the enemy has time to engage.
A more capable enemy would be able to detect the rocket earlier and shoot it down, so missions would still be possible but harder to plan (landing site has to be outside the range of nearby SAMs and far enough from airbases to buy the soldiers time before enemy jets can be scrambled to shoot down the rocket and bomb the landing site).

And on top of all that, they could just use the rocket to deploy paratroopers and avoid the need to complete a landing.

>>9198342

The point is to make humans have a colony on another planet, and the reasons are fairly evident: more baskets for the eggs being the most important one.

>>9198373
How would they get hundreds of troops out of that little hatch? The rocket would run out of fuel hovering.

>>9198334
Elon has been very critical of nuclear power on earth, usually accompanied by "well we have a nuclear reactor in the sky that comes up every morning"
>>9198380
Could just the paratroopers just hop out of the cargo version in space, then equip each solider with his own heat shield.
Or just reconfigure the top part to be pic related.

>>9198392
That's not really viable at all. The thing wouldn't even enough fuel to get back anyway.

so what did they mean by that

So what will flat earthers say when their entire world view can be btfo for the price of a plane ticket?

>>9198401
Watching the video, just passed that part a second ago.

They accelerate in the opposite direction of where they want the fuel to go. Acceleration and any other misc crap forces it into the correct ship.

>>9198396
You wouldn't need it to get back. Have it ment to be an expendable drop pod for troops or armored vehicles.

>>9198008

>Orbital ATK, LM, and all the other big aerospace companies

Do not have reusable rockets and charge hundreds of millions for launch. They are largely a pork barrel.

>>9198142
he called it a chomper

>>9198401
>so what did they mean by that

The rocket is designed so that it only has enough fuel to get into space and to land again, for the most part. To go beyond Earth Orbit, more fuel is needed than that. To avoid making an even bigger rocket to land an even smaller amount of useful stuff, they intend to use orbital refueling so that the same rocket stage that finished getting them into space can be used to take them to their destination in space, and back to Earth again.

>>9197979
He made payload to orbit prices so low other companies were forced to low them.

>>9198196

>How safe and reliable is orbital refueling?

There is no deep reason it cant be made safe enough. More importantly, routine and frequent orbital refueling is inevitable if we ever want to achieve anything substantial in space. There is no way around that.

Why the fuck are governments even funding some worhtless mars rovers that just study the climate for years and provide some stupid graphs when based mars man can send a fuckhuge rocket there in 5 years?

>>9198420
Don't count your chickens before they've hatched, but he's stepping on a lot of egos with this proposal, the voices declaring SpaceX's inevitable demise will reach new heights.

>>9198380
They could have SpaceX design a model with several hatches, or with the soldiers dropping in a small number of shared capsules rather than individually.

>>9198396
Getting back is less of an issue with this sort of thing.
These rockets would probably be the first shots fired in a longer-term conflict. The soldiers who get off the rockets would set up and secure a forward base, and eventually get rotated out by a more conventional vehicle.

Private sector has no place in Space.

Any attempts for human presence there should be joint international endeavor because space belongs to all people on Earth and monopolizing it for the few is not acceptable.

>>9198438
>and nationalism doesnt do that?

They aren't sufficiently inclusive of the socialist's utopian dream, where everyone gets to participate and directly enjoy the benefits of the glory of human achievement without having any obligations to be useful or good at what they do. Typically people don't realize that this also kills the human spirit and desire to achieve and strive for something great when individual greatness is consumed by the masses of mediocrity around them.

>>9198196
Probably safer than doing the same thing on Earth, since there's no weather or even atmosphere to screw things up. Their chosen method actually simplifies things by eliminating the need for pumps (they use acceleration to push the fuel over) and for a special-purpose in-orbit docking interface (they reuse the first-stage interface).
They'd have to get in-orbit rendezvous and docking right to pull this off, but judging by their success with propulsive landing they should be able to get this one right as well.

>>9198196
>How safe and reliable is orbital refueling?

No one knows for sure. It's never actually been done before.

>>9198452
>Their chosen method actually simplifies things by eliminating the need for pumps (they use acceleration to push the fuel over)

No, they only use acceleration to settle the propellant. They still need to pump it over.

>>9198459
>No, they only use acceleration to settle the propellant. They still need to pump it over.

Orbital refueling as depicted in today's presentation works the same way as tank settling. A tiny amount of acceleration is used to drain the fuel into the "lowest" reservoir.

>>9198445
ooh la la somebody is gunna get laid in college
all i was trying to say that neither option is perfect so lets try the currently more efficient one.
jeez untwist your polysci panties

>>9198463
Would a tiny bit be enough? Accelerating through the entire fueling process will burn a lot of fuel itself, and fuck the orbit up.

>>9198469
Acceleration is indistinguishable from gravitation; basically any noticeable amount will get your fuel where you want it to go, eventually. The effects on orbit parameters probably wouldn't be dramatic.

"Eventually", what sort of delta v will be required to get it all across? How much fuel will that use up and what will it do to the orbit? It takes like half an hour to fuel up a Falcon 9 on earth at 1g, you can't accelerate at 1g for half an hour in space.

>>9198480
>Fuck off commie

Work on your reading comprehension, bro. I said it's socialism that fails to give value commensurate to what someone puts into it.

>>9198463

The presentation explicitly says that propellant is settled by milli-g acceleration using RCS. Not transferred, settled. Elon stumbling through his words is ambiguous and can mean anything from the settled propellant being pumped over to transfer by acceleration only.

>>9198485
I honestly don't know. The SpaceX presentation says that they'll use milli-G acceleration to accelerate the ship against the fuel so that it will settle. How much Delta-V is involved, how much fuel is burned, and how long it will take is unknown to me.

>>9198488
Did you mean to point to a different post?

>>9198489

>Did you mean to point to a different post?

No.

There is very little delta-v needed for fuel settling at the bottom of the tank where the pump inlet is. Intermittent milli-g thrusts are enough.

A lot more may be required if they want to actually transfer the propellant using acceleration only.

>>9198487
>fuck off commie

I guess that was ment for

>>9198437

>>9198428
This is what it feels like. It's just "lel we're doing cool science look at this exciting presentation about the temperature on venus". Uhh, no. People want to be inspired and government space programs are so uninspiring nowadays.

>>9198491
Okay, but you basically restated exactly what I said in the first place while sounding contradictory.

So is this guy legit?

This begs the question- what's docking with what, here?

>>9198425
are those sizes correct? the iss can barely fit a dozen people at max capacity, how is the spaceship supposed to carry 100?

>>9198661

Keep in mind that the internal (open air) diameter of those ISS modules is quite small compared to the outside. The ISS is also a laboratory.

The ship will have ~40 small cabins where people sleep in shifts, and communal space for those awake.

>>9198518
Even if possible it wouldn't be allowed en masse due to ethics. The leaders on top will be a different story though.

I'm just worried space colonization might be murdered in its infancy with some ecological "save the microbes don't irradiate space!" shit flinging campaign.

China doesn't give a flying fuck about ethics and religious right of the US. They're going to become the king of genetic engineering biotech hell or high water. The US is going to lag further and further behind until it fails as a country, because half the ruling body wants to take it back 200 years; and the other half can't get enough votes to prevent that.

Can't wait to shitpost on Mars!

Ultimately it'll come down to the question of all past fuckhuge rockets designs:
Will enough companies and governments start shooting enough crap to space to actually make this economically viable.
Because if they don't, this project will die in a few years without funding.

Try 5-7 minutes. Any internet service from Earth to Mars would be laser based. Takes light 3 minutes at closest approach between Earth and Mars, to travel the distance.

>>9198292
Alright well I was wrong on both of my timelines god it seems like its been so much longer. Point remains, spacex started their rocketry program in earnest well after virgin and they sure aren't looking to slow down.

>>9198851
8 minutes actually, since your request needs time to travel all the way back
and at the farthest distance, it's 20 minutes one way, or 40 minutes for two way

>>9198851

You seem to have missed the bit where it's reusable. Not like, space-shuttle reusable, but like 747 reusable. You just put more fuel in and send it up again.

Despite having the largest capacity ever, it will be cheaper to fly than any previous orbital rocket, even the smallest ones.

>>9198918
>reusable
Yeah just like they reused all those Falcons. Oh wait...

>>9198920
anon they literally have reused multiple falcons did you forget what year it is?

>>9198936
>they literally have reused multiple falcons
No they didn't. None of the landed satages were reused.

>>9198920
Falcon 9 was always going to be an incremental expendable-to-reusable development vehicle. They've demonstrated recovery and reuse, and are putting the finishing touches on it for rapid reuse.

Now that they've gained that experience and developed that technology, they're building a vehicle that's designed from the start to only be reusable.

32 here and if he lands the first 2 cargo ships in 2022 or 2024 I'm going to focus all my time on money so I can live to see Mars.Fuck children and leaving anything behind when you die.
If it turns out the time table is off by 20-30 years you can always watch documentarys.

>>9198917
Considering the age of most astronauts, You'd be average in age for the mars colony mission
Go learn yourself useful knowledge and you can become spaceman
>>9198976
>goal is a colony
>doesn't want children
you're a special kind of retarded, aren't you

>>9198980
And yet you didnt get my point.
Scenario 1: Time table is met and I focus everything on living to see Mars.
Scenario 2: Time table is not met and I stay here and live a normal life with family and watch the progress from Earth. Focusing on leaving something for my descendants.

I find myself really unsure about the whole rocket airline to fly people half way across the world. It really feels like the Concord dilemma all over again. I can't see any way to drive cost down so far even with a reusable rocket to match economy class tickets.

Is Elon's lack of charisma hurting SpaceX? I think they need to hire a better speaker.

>>9199053
SpaceX is doing better than it ever has before, so I don't think it's much of an issue

>>9199053
Elon is probably the most popular CEO alive

>>9199064
>>9199070
I guess you are right. It just seems like he is not able to make his ideas sound as interesting as they actually are. But on the other hand, it seems more genuine this way.

>>9199075
>he is not able to make his ideas sound as interesting as they actually are
He doesn't need to when he got his pretty CGI videos.

>>9199075
It doesn't really matter how interesting they are to general public since SpaceX is a private company.

we tryna go 2 space n shit nigga i swear2god man

The first thing humans should do on mars is go see if Sojourner is still alive, hopelessly trying to communicate with its dead base station... it doesn’t deserve to be left in the dark like that. Makes me tear up. Twenty years without any communication, it must really suck for the little dude

it's not them being dense
they know what it means, but since Musk gave it that name, that is what they have to call it
they'll switch it out to "Big Falcon Rocket" to stay family friendly however

Woah, we can even go to the moon with this.
All it takes for that is to:
>1. launch a BFR space ship to low earth orbit
>2. launch BFR tanker ship to orbit
>3. refuel the space ship
>4. repeat 2 and 3 until full
>3. Increase space ship orbit to eliptical orbit

Oh boy, I sure hope those astronauts are comfy up there on their 10 year mission to the moon.

>>9199221

Characters are a bit stereotypical and the plot has a high sci-fi element that annoys me in all this low sci-fi goodness, but the setting is aces and the special effects are pretty good.

Now the eurangutans want to flee from the disaster they provoked.

You are going to die here. And the ones who manage to survive there , we will make sure to nuke them all from distance.

Sounds like shitty parenting to me.

>>9199353
Friendly reminder that there's people out there who seriously think that earth is flat ^^

That's a big rocket.

>>9199367

take a look at the current state of humanity and tell me if good parenting is the rule or the exception

>>9199353
It's a SpaceX thread, this is like our designated shitting thread

>>9199387

Elon could potentially sell a BFR to NASA/EASA/JAXA for $1Bn and make that ship a permanent attachment to the ISS. The cargo & living space volume inside that rocket is greater than ll of the ISS. Assuming that at any given time there's only 10 people living in the ISS and given that the BFR is expected to ferry around 100 people w/ 2-3 people per onboard room. Then, there's an immense amount of space station potential out of that ship.

>>9198401
>that scale

>>9199306
I thought sci would be able to realize that races aren't a collective mind, I thought wrong I guess

>>9199450
The ISS is old, shitty, and outdated
The cargo capacity of the BFR would let them send an entirely new ISS up in 2 launches, with 100 tons to spare

They might as well spend the money on constructing Elysium full scale, or an O'Neil cylinder, since the costs would be tiny compared to what nations have to throw around

150 tons is a lot of fucking material, and the motherfucker wants to mass produce these rockets
where is kickstarter, in a few years I'd probably be able to drum up enough money to fund a space habitat for me and whoever pitched in money

>>9199472
Moon base alpha should come first though.

It's entirly possible to go from the Lunar surface to orbit using nothing but electricity.
I think it would be cheaper to mine and construct it from the moon rather than launching from Earth.

>>9198401
>Be gentle with me senpai. Only milli Newton for now!

This is genius.

>>9199472

That's true, but there's a lot of experiments that are still running up there and intend to run for another handful of years. Perhaps Elon should have a Cargo version of the BFR built without the 4 big raptors and only the two small raptors. Reduce the total fuel tank requirements and instead cannibalize that space for usable internal volume.

Build 4 of these fuckers with a docking torus that would be taken up into space by a standard cargo BFR and in MEO, create a new-gen ISS composed of 4 Science class BFRs connected to a docking torus.

>>9199387
It's no bigger than just one of the radiators sempai

>>9199496

RIP

>>9198409
>>9198401
This plan has so many untested ideas It'll be a miracle if we see it's first actual mission in 2026.

>>9199522

Its really not. Its basically applying inertia to fuel transference. Instead of using electricity to rely on pumps, its literally using one of the basic fundamental principles of physics to cheaply move 1100 tons of fuel. Its absolutely genius.

Anyone else unhappy with the aesthetics of the BFR?

It just looks clumsy and fat. Like my ex gf

Also that assymetrical delta wing?

>>9199540
Yeah it's pretty genius. And it's the same for a lot of other things.
Smart, totally possible, but never been done before (at least not in this context).
There is just so much new stuff you have to think about and put into the rocket and so much room to say "oops we didn't really think about that"

It was the same with falcon heavy.

>>9199550

That's fair.

Conservation of momentum makes space travel a meme.

>>9199229
Yeah dude musk is some kinda troll, the tesla cars spell out sexy (Models S, 3, X, Y) and he named his tunneling project the boring company and their goal is beating a snail named gary in movement speed.
