Then why hasn't he done anything of any use yet?

>>9221826
He's been busy building giant dildos

>>9221831
Just give up already Bezos.

15 minutes.

Insprucker is a national treasurer

It will blow up.

As much as I love SpaceX, calling the drone landing ship "just read the instructions" makes me hope it crashes cause someone forgot 1 step.

T MINUS THREE MINUTES MOTHERFUCKERS

T minus two Minutes

Lift off.

seems a bit sluggish today. Then again it's already going 12000 km/h

it's sorta sad that these are now routine. we're landing rockets, and only 7 people are in this thread!

inb4 drone ship cameras freeze up and miss the actual landing

>>9221953
Just wait until 2020 when everyone is watching that first rocket to Mars

>>9221958
FH thread should be quite popular.

>>9221956
Lol fuck you

WE DID IT

spooky landing!

>>9221953
It's actually really good that they have become routine

Even the SpaceX staff sound less enthusiastic lol

Onto the next challenge

>>9221956
Requires faith

>>9221956
called it

>>9221967
still have 2nd stage experimental reentry, fairing capture, west coast RTLS, to look forward too. Then FH and then BFR after that

INTERMISSION

Is FH happening this year? I want to see 3-booster landing.

>>9221987

>>9221987
>>9221988
FH demo still pencilled in for Nov/Dec 2017

Although given the tone of Elon's speech last week at IAC it's likely to be delayed again

He kept pointing out the unexpected difficulty of just strapping three first stages together

Well at least NASA is competing strongly

People still believe this scam?

>>9221994

>>9221956
They really do need a second small drone ship nearby with some cameras. Otherwise, we have to wait for the helicopter cams later on.

the Spaceflight Inc 50-sat mission should be fun to see the deployments

What was that one deployment some time ago that had tons and tons of sats being shat out like it was laying a track for Pacman?

>>9222037
well the Indians did a bunch of multisat missions. Dunno about SpX

>>9222106
Ta da, now you know why the Apollo missions were hardly important to most people after 11. There were the same exact feelings towards landing on the fucking moon. Seems crazy, but it’s true... it’s hard to imagine feeling meh towards a mars landing, but we’ll not care after the tenth one or so

>>9222167
>we’ll not care

Humans are broken

>>9222167
Needs more disasters

>>9221790
Did Elon really say people on mars before 2024? What the fuck is wrong with him. Years ago I admired him and thought he was highly intelligent. But then he couldn't stop talking about muuuh climate change fearmongering, PV, mars, hyperloop, dangerous AI and other stupid shit. At first I thought he just spouted this nonsense for PR but over time I felt that it was just too much and he really is just a dumb retard who got rich through luck and very hard work.

>>9222245
Weeelll if you're so smart, how come you ain't got no rocket imperium?

Years ago you admired him, when he was talking "stupid shit" about reusable rockets that are just impossible?

>>9222097
You have my keks.

>>9222309
>when he was talking "stupid shit" about reusable rockets that are just impossible?
Except that wasn't stupid shit. Nor was it revolutionary or a novel idea. Rocketry is such a tightly regulated field that of course there is near zero competition and innovation in launch vehicles. It's all government programs.

Even if you ignore the strict regulations, almost everything is government related. There is almost no commercial / free market. Satellites are already saturated and market is declining. It does not pay off anymore to launch a satellite and the only entities who do it are government related where lucrativity doesn't matter because the money is stolen from tax payers or good will from companies with too much money, such as facebook wanting facebook access for free everywhere on the world via satellites.

The people who made money via satellites used them for broadcasting stuff like TV channels or selling earth images and both are outdated now.

There is no market for it. SpaceX depends 100% on government for its existence. Space from the very beginning has just been one huge waste of money.

>>9222335
Only SpaceX is going to be putting up its own satellites for satellite internet next year (Starklink?) It is intended to be world wide and super cheap. Basically, taking the rug out from under everyone else, except for the lag.

Get ready for India, central Africa, Eastern Russia, Mongolia, and other places to start shitposting on 4chan soon after that.

>>9222350
>SpaceX is going to be putting up its own satellites for satellite internet next year
How is this supposed to be lucrative? Shit data transfer for ridiculous cost. How much per satellite including launch costs, how long will they last and what is their data transfer rate?

>>9222356
They will last five years or so. Data transfer will be super fast. Lower lag than some physical lines; C in space is faster than C in a cable. The home unit will be pizza box sized.

StarLink will make spacex billions upon billions of dollars. Can’t wait for them to go public...

>>9222366
>>9222356
I had Hughesnet for a year. It was terrible for lag, for gaming purposes, fine for everything else. The worst part was their data plans. Basically fucks you every way possible then throttles you to dial-up speeds as penalty. SpaceX should be able to totally wreck that in short order.

>>9222366
All you provide are words. Where are the numbers? What altitude are the satellites? How does the data transfer work and what are the power losses?

>>9222388
I think this is as much as known right now,

http://www.floridatoday.com/story/tech/science/space/2017/09/19/spacex-files-trademark-starlink-satellite-broadband-internet-constellation-elon-musk/680714001/

>>9222396
So basically absolutely nothing yet people suck Elon's dick so hard the lack of air kills what little remains of their brain.

>>9222379
>Hughesnet
Looked it up real quick. As expected it requires you to install a satellite dish so zero mobile usability. 10 GB per month costs 50$. For that amount of money you can get 1gig/sec connections in some places and I pay less than that for 250 meg. So basically what you get for 50$ is what others get in less than a minute of internet for maybe 1/50000th the cost. Exactly this is the problem with satellites. Ridiculously more expensive. Only specialized utility for shitholes in the middle of nowhere.

So posters like >>9222366 are dipshitting out of their ass and have no idea how it will work and how it will make money.

>>9222406
Just saw this.
>Currently I have the $90 plan which gives me 20 GB per month and ends up to be $116 per month (with taxes, etc)
So apparently there are hidden costs and it is actually even more expensive. Bravo. Even if spacex manages to lower the costs tenfold which should be realistic it will still be shit.

>>9222406
You’re retarded and I feel dumb having to spoonfeed you

http://licensing.fcc.gov/myibfs/download.do?attachment_key=1190019

>>9221991
It should be scrapped. Fuck Falcon Heavy

>>9222467
>It should be scrapped. Fuck Falcon Heavy
Elon agrees

F9 and FH will become redundant as he focuses on BFR

Sad but necessary considering the only marginal gains offered by FH. My guess is they'll do the maiden voyage as a demo and then move straight onto BFR

>>9222488
What if it explodes? This fucking project already drained years and years of their time. I fear the DEMO event.

>>9222406

The point is that SpaceX constellation will be hundreds of satellites in LEO instead of handful of GEO birds

This will allow SpaceX to offer latency comparable to fiber internet, huge amounts of bandwidth and no need for large dishes

Large LEO constellations are a very different beast than todays satellite internet

>>9222459
Zero practical information such as costs, just a rough theoretical framework.

Did you even look at the document yourself? What do you think how expensive it will be to build and launch several thousand satellites? This isn't an issue of surface coverage or bandwidth or athmospheric disposal. It is an issue of cost and feasibility.

>>9222406
>So basically absolutely nothing yet

What part of "launching next year" did you interpret as "already completed, here's the specs"?

>zero mobile usability.

You just realign the dish from where ever you happen to be. Satphones don't need to do that though. Also, you were told Hughesnet is terrible.

>>9222413
You probably shouldn't compare Hughesnet to SpaceX when we know next to nothing about the latter.

>>9222526
Seems you lack critical thinking and are simply sperging out, kid.

>>9222513
>The point is that SpaceX constellation will be hundreds of satellites in LEO instead of handful of GEO birds

I think the latest number was 12,000 satellites in orbit for the Starlink internet thing.

>>9222335
>money is stolen from tax payers
>huge waste of money.
Oh no, it's one of those freemarketeers.
Making money is a huge waste of human work and resources.

>>9222491
If it explodes I imagine they will cancel it totally

>>9223013
Most likely not.

>>9222406
>Exactly this is the problem with satellites.
If you think it's bad just because it's "a satellite", then you're a moron. Hughes sucks simply because it's a GEO satellite. It's all about the distance. We only have sucky GEO right now because it's the only orbit where you don't have to have to launch a hundred or more.

See how far away GEO is? That is where the lag comes from. The sucky bandwidth comes from there being only one satellite that everybody has to talk to. See where Iridium is? That's like 5% of the altitude, which means 5% of the lag.

>>9224065
Love that image.

Hughesnet uses 2 main sats now; which has increased their bandwidth and speed a great deal, but they still cap data and bandwidth like hungry Jews. The last one launched last year, "EchoStar XIX" operates in geostationary orbit, at a longitude of 97.1 degrees west.

EchoStar XIX
>35,783.80km altitude

http://www.n2yo.com/?s=38551

Their old one,

Spaceway-3
>35786.80km altitude
http://www.n2yo.com/?s=32018

Since SpaceX's Starlink will have 12,000 satellites (fug) as its network they must be very very close to the Earth. Officially between, "1,110km and 1,325km." Compare that to the ISS at 422km and Iridium-104 at 780km. The air travel (bird fly) shortest distance from United States to Europe is 7,895.1 km. Total round trip distance for Starlink communications would be 2,220km to 2,650km.

Geo orbit lag time is 240ms - 279ms for the round trip.
Starlink lag time would be less than 10ms round trip.

In regard to his earth to earth meme rockets why not just try to design an aeroplane thaat can go into the upper atmosphere? Can't you just propel it up high and fast enough with just a small amount of fuel and coast? Sure it might not be a 40 minute journey but shit it might shave a couple hours off

>>9224383
That's what they are doing already. Only wings are not needed anymore.

>>9224384

Except you need the lift to keep in the air otherwise you're just making a rocket and the fuel is way too expensive. It's also good to have wings in case things go wrong.

>>9224387
They leave the atmosphere so there's no air at all. They should go ballistic for a while too.

>in case things go wrong.

At best, an abort would probably have a cabin separation which would land using a parachute. Wings are pretty much useless and require inordinate amounts of support systems. That was one of the major flaws in NASA's space shuttle design. Basically, those were engineering gone wrong.

>>9221956
how the fuck has this happened twice

>>9221936
>He's never read any Iain M. Banks

>>9224470
It has happened several times.

>>9224507
Culture series is haphazard, some of them are good and some are just shit. Too bad Banks is such a sick fuck in the head.

When will spacex just die off like it was supposed to 5 years ago?

>>9222053
>designated shitting orbit

>>9224512
I'm really enjoying them so far. What makes Banks sick in the head?

BFR will never have abort capabilities. Ignoring the weight penalty, a short system of that magnitude would introduce more failure modes than it prevents. Designing the craft to be safe to begin with is easier long term

>>9224518
Never.
SpaceX is taking us to Mars and there's nothing you can do to stop it.
Musk will become emperor of Mars and establish the 4th Reich

ECHOSTAR 105/SES-11 MISSION

SpaceX is targeting launch of EchoStar 105/SES-11 from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center, Florida. The two-hour launch window opens on Wednesday, October 11 at 6:53 p.m. EDT, or 22:53 UTC. A two-hour backup launch window opens on Thursday, October 12 at 6:53 p.m. EDT, or 22:53 UTC. The satellite will be deployed approximately 36 minutes after liftoff.

https://www.youtube.com/watch?v=iv1zeGSvhIw

>>9224387

>and the fuel is way too expensive

fuel is very very cheap

>>9226301
Compared to the cost of a rocket, yes. Which is why they are trying to make landings a thing. Fuel is also very cheap compared to a new airplane every time.

Given the distance involved and that it sounds like he wants to carry a super-jumbo worth of passengers, it might still not be that bad compared to a jet plane struggling through the air for most of a day. And since this won't be going to orbit, it should take a lot less fuel than an orbital launch.

>>9224530
Shit eaters
Chairmaker
Wasp Factory (wtf?)
Gender bending degeneracy

Just to name a few things that are not even remotely needed for the books to be really good in their own right. There's a lot more, enough that I finally stopped reading them.

>>9226356
Seems it will carry 100 passenger in 40 cabins and have big communal areas according to the pic in >>9224460 A "737 MAX 200" jetline carries 200 people. But, that's like 5-12 hours of flight time depending on where you are going in it.

>>9226478
Aye, the shit eating cultists were vomit inducing, but an excellent representation of just how mental people could get in a universe of limitless possibilities.
The chairmaker from UoW was sick, but again we're talking about someone not from the Culture who themselves have an incredibly permissible society, so getting to the bottom of exactly why he was so anti-Culture while at the same time fighting for them (for his redemption) was what was interesting.
Not read the Wasp Factory yet, really looking forward to that.
As for the gender bending, it makes sense in a society where you can flit back and forth with no negative connotations or permanent consequences. The problem that we (and by we, I'm assuming you're a bit of a /pol/ack here) have with it at the moment is that a bunch of retarded autists who listened too to much identity politics nonsense got it in their head they can be anything they ever wanted and everyone just has to accept it; the technology available today doesn't support their high expectations and as a result everyone loses. But in Banks' world, you can change gender at the chromosomal level. What's the problem with that? Degeneracy = uselessness/non-productiveness essentially. If you could genuinely for all intents and purposes change your gender and back for a time, wouldn't it be an illuminating experience, especially in a society where everyone lives 300+ years, resources are practically free and immortality is attainable? It's a completely reversible process. The problem with the process today is that it's an irreversible clusterfuck and ruins people's lives.

>>9226686

>>9224533
ya but how do you do that. it needs to be safe like an airliner

>>9226504
>Seems it will carry 100 passenger in 40 cabins
I think that's for the Mars version. Why do you need "cabins" for a 30-minute ballistic flight?

hi can someone explain why the old space programs had so nice picture quality? just click through the pictures today stuff looks bland and boring in comparison

>>9226742
Jet planes don't have an "abort" after they reach V1. If you can't fly it back, it's game over.

>>9226802
For the orgy.

>>9226686
Wasp Factory was his first book. It is basically like the average life of a /b/tard from /b/ circa 2004-2006.

>gender bending...

People wanting to do that need help on a mental level, not a hugbox or entertainment media role models. The only time where that sort of technology would be okay to use would be if suddenly group or colony of people lost all of one sex of their society and had to resort to some of them changing genders to continue to have children. That in itself would make for an okay book I suppose.

>>9226867
>when the mile high club isn't high enough anymore

>>9226891
Wouldn't you want to brag, "yeah, I've had sex in space". That'd be the first thing I'd do with my own private cabin.
