>Fourth flight

B-B-BUT REUSABILITY IS A MEME

According to the Starlink website, its users will live in comfy houses by a lake

>>11135328
Damn that is comfy

>>11135322
Playing devils advocate here, it could turn out he is spending more on refurbishing them than a new one would cost like the shuttle.
I doubt that is the case but unless numbers are made public we wouldn't know.

>>11135360
Shuttle was torn apart to some extent - while they don’t even have to ship cores back to CA for Falcon. As far as I know hardly anything is taken off.

>>11135314
So when can I get space internet and how much will it cost

if you can't fps game on it I don't want it,and I know you cant because sat internet sucks and isn't new.

Just put people on mars already faggot

>>11135368
>I know you cant because sat internet sucks and isn't new

So you don't even know what you are talking about.

>>11135368
>next year if you're in the northern latitudes
>you will be able to; this is a MEO/LEO constellation. Light travels at .7c in fiber, 1c in a vacuum. the 550km hops up and down are negligible

>>11135372
They've had dish internet for years it's slow and you can't game on it. How is his going to be better?

>>11135368
You will get lower ping

>>11135376
Because the satellites are at a few hundred ks orbit and not 28 fucking thousand ks you retard.

>>11135368
>yet another retard thinking it's trying to compete with cable / fiber
It's going to be low bandwidth / low ping with 2 primary target markets:
Places with limited / no internet infrastructure (rural / 3rd world)
People that need extremely low ping between continents (stock traders)

>>11135397
Good thing that the vast majority of the world has neither cable nor fiber. And it will be vastly superior to the shit shoot that is ADSL.

>>11135397
200 different HST's paid 2.8 billion fucking dollars for a 13ms cut between Chicago and New Jersey a few years back

>>11135315

>>11135368
>So when can I get space internet and how much will it cost
Mid next year, and Shotwell is targeting $80+-$20 for possibly 100-500Mbps

With latencies in sub 10-20ms, no fps issues with any game

>>11135397
I'm guessing that it'll use some kind of patch antenna, maybe in the 30cm range. It probably won't do mobile reception very well, but it'll probably work great for a parked RV, at least when it's not parked under trees.
So a third market, whether they target it or not, could be the snowbird boomer road yacht crowd.

Reminder that the train is neato https://www.youtube.com/watch?v=cycLZQtM8HU

>>11135419
Would the phased array antenna work if it's slowly rocking, like on a sailboat? Or does it need to be still? That's a huge fucking market right there.

>>11135422
they stuck it on a C12-J
https://spacenews.com/air-force-enthusiastic-about-commercial-leo-broadband-after-successful-tests/
AC-130 comes next

>>11135436
Nice, every single ship and aeroplane will be on this as soon as it's available to them since they have huge satellite internet bills.

>>11135420
Nice.

Mercury transit is tomorrow, don't forget
>>11135042

>https://caseyhandmer.wordpress.com/2019/11/02/starlink-is-a-very-big-deal/

Just read the detailed analysis. Jesus Christ. If its anywhere close to accurate with the numbers, that'll ruin most of ISP monopolies in rural/town areas.

>>11135422
Good question. Tilting is probably a different problem from translation (sideways motion). Instinctively I think tilting would be more troublesome. Maybe you could mount it on a steadicam handle?
Back around 10 years ago, for a short time I worked on a project for satellite radio in a car with a rotating 16-patch phased antenna (about 8cm), but the project died before it could get very far. (home office was spending too much on bullshit like office ping-pong tables, and something had to go)
It did have to rotate to keep adjusted, but it didn't do live play (it transmitted a bunch of songs that would get downloaded to local flash), because of bridges and shit.
I remember they did the patch antenna thing because proper chipsets were only sold for military-tier stuff and were too expensive. I think it used an FPGA to decode because I wrote a driver so it could be loaded when Linux booted.

>>11135447
it's important to keep in mind that SpaceX wants to partner with ISP's; it won't work unless they do. Partly due to the $$$ from backloadbone routing, and also without laser interlinks a shitton of ground stations is needed. ISP's aren't the enemy of SpaceX. It's a mutually benefiting relationship (for now)

>>11135451
SpaceX has no enemies. They have competitors. Starlink will not just be sold to ISPs, but also to private individuals.

>>11135447
ISPs are going to move heaven and earth in every single country to try and stop this in their country. This is legit suicide by handgun to the back of the head tier industry disruption.

I'm still optimistic but these pieces of shit make way too much money to just hand it over.

>>11135451
Interlinks are coming pretty soon, I don't see why they would add another layer of parasites rather than sell directly.

>>11135457
you still need groundstations for interlinks

>>11135451
>>11135457
ISPs partnership maybe required in some countries with monopoly protection/censorship regime.

>https://spacenews.com/spacex-plans-to-start-offering-starlink-broadband-services-in-2020/

SpaceX will have to hire a whole new workforce to deal with sales, tech support and product engineering. User terminals are a major concern. “The more engineering we do on the user terminal, the less service people we will have to hire,” said Shotwell, Terminals are one aspect of the Starlink business that the company has to “get right,” she said.

When consumers sign up, “they are going to receive a box from SpaceX” with a user terminal and a cord, said Shotwell. How that gets connected and where the terminals should be placed in someone’s home are still issues to be ironed out. “We still have a lot to do to get that right,” said Shotwell. “Knowing Elon, he wants everything to be beautiful. So the user terminal will be beautiful.”

The price point is also being studied. Shotwell said millions of people in the U.S. pay $80 per month to get “crappy service.” She didn’t say whether Starlink will cost more or less than $80 per month but suggested that would be a segment of the public the company would target as well as rural areas that currently have no connectivity.

Outside the United States, SpaceX is working nation by nation to get authorization to offer the service. “Every country has its own process,” said Shotwell.

SpaceX is racing to get Starlink in operation as several other companies continue to build competing broadband constellations. Shotwell said there is probably room in the market for at least two competitors. “If we do well and make money, there will be competitors.”

As more Starlink launches are planned, SpaceX wants to use previously flown Falcon boosters as much as possible, said Shotwell. “I think we’ll manage the fleet how best we manage the fleet,” she said. “Our intent is to use Starlink to push the capability of those boosters and see how many missions they can do.”

>>11135467
What for? If you have interlinks you are going directly point to point.

>>11135472
It'll be a sexy pizza box with a PoE cable and another Ethernet cable that runs to a router.

>>11135478
To connect the Starlink network with the rest of the internet

>>11135482

>>11135491

So did a bit of math. There are roughly 60 million rural population in the US. If Starlink offers 100 Mbps @ $50 per month and 20%(12Million) of those rural population switch, that's $7 billion per of steady revenue. Starlink/Starship's entire project will be funded for few years with just the first year.

Starship can take 400 starlink satellites. That's a long train.

>>11135504
also >>11135403
not to mention >>11135439
and >https://spacenews.com/spacex-sees-u-s-army-as-possible-customer-for-starlink-and-starship/

They'll reach initial operational capacity in just five or six more launches. They'll have the largest satellite fleet by Q1 next year. They'll own the majority of satellites in existence, period, in less than five years. Starlink doesn't even technically need SS/SH to be a workable business model- with the money it stands to make, F9 could very well be the workhorse launcher of the constellation and it would still be perfectly economically viable.

There are children being born right now who will not remember a time before there were twinkling grids of Starlink sats along the horizon at dawn and dusk.

>>11135523
Who has more satellite constellation than SpaceX right now? I can think of Iridium at 72 or something, who else?

>>11135526
Yeah pretty sure it's iridium. Tomorrow SpaceX will be the largest satellite operator.

reminder that some people are morons, and to not let them get under your skin. Expect more and more of this shit as Starlink becomes known to the average pleb

>>11135526
I think it's Planet Labs with 200-300. They're cubesat-tier vehicles, but sophisticated enough to provide the earth imaging that the company sells.

In the same rough tier of size and complexity, I think Iridium is the closest direct comparison, and they'll surpass it with tomorrow's launch.

>>11135538
None of those are as stupid as the "Starlink can hurt the culture of the Sentinelese" comment I've read a while ago.

>>11135540
Nah they have like 150

>>11135538
At this point I just think they're funny and a little sad.

>>11135540
>Planet Labs
Wiki says they have 150(out of 300) active satellites in orbit. So SpaceX needs tomorrow and another 60 launch to surpass them.

>>11135549
Ol Musky might have them beat by Christmas then

>>11135504
Aside from that, with proper negotiations, they'll probably get >$100B from all of their 30K Starlink
Shits' gonna be insane.

Imagine $100 billion Elon has that allows him to build 1000 Starship to make a Mars colony all by himself and retire there.

s-sorry...

Looking forward to seeing this train. I missed the last one

>>11135420
Is there some way for me to track if/when it will fly over my location?

>>11135739
download previsat or satorbit or something and plug in the TLE's which people will post in the satobs mailing list

>>11135739
this is my best pass at 542pm tomorrow. don't thunk they'll be spread out that far by then, but I could be wrong. This of course assumes an on time launch.

>>11135470
This might be a stupid question, but is it feasible for SpaceX to add cameras with similar hardware to Planet Labs' to their Starlink satellites and offer their own imagine service?

>>11135793
SpaceX/Elon have stated that ground (and sky) imagining hardware is a future feature. That and allowing organizations to slap some scientific hardware etc on a few of the sats.
13000 LEO/MEO cameras trained downwards would be a great asset for a variety of industries and services

Easy way to find the train https://james.darpinian.com/satellites/?special=starlink-2019-11

Does anyone know how I can find out if something @ 500km altitude will be in sunlight at a given time and lat / long?

According to >>11135824 it'll be over me 1.5 hours before sunrise and I want to know if it'll be lit or not.

>>11135866
I like previsat; it can be configured for different levels of illumination and other characteristics. Nonetheless the web utility you used is set up to only show times when it is illuminated, so you should be good.

>>11135876
>>11135866
That is, previsat will also show the specific area/time where the object will be illuminated as shown here >>11135792

>>11135876
>>11135881
Thanks, I'll try to figure out PreviSat, looks like a powerful tool.

>>11135890
To put in an object just create a .txt and paste in the TLE, then load the file into the program. When proper TLE’s are posted on satobs keep in mind if it’s for the front or back of the train or whatever.

Took this pic with my phone during the last train

I hope the feed of Falcon barfing Starlinks out is smooth this time around.

>>11135328
Does this come with the subscription?

Where will the satellite's be visible from?

>>11135929
it was smooth last time, but they deliberately cut the feed to hide the satellite deployment mechanism

>>11136025
I would 100% believe that

>>11136194
What is there to hide?

Great, SpaceX went poo in loo as well

Yo where is the feed without pleb brainlet commentary.

The fuck is going on with the countdown clock?

>>11136623
They did away with that a while ago. Closest they have is mission control audio feed.

>>11136623
See >>11136600

Part of me wants to watch the estronaut feed one of these days out of curiosity, but I fear it'd RUD on the one time I did

One minute.

lets go bois

I love the look of reused boosters, seem way more industrial than the clean ones.

Pls no challenger-mode

USA

It's beautiful

How many times can they reuse a booster....?

I miss Houston voice for countdown.

>>11136649
The goal is 10, I think with starlink they might go until failure as Musk has said they can lose a stack without it being a big deal.

>>11136649
Maybe 10...

What flew by the camera

>>11136657

>>11136737
~15 mins until circularization burn, no idea when deployment is.

I know Rocket Lab did. Maybe you're thinking of that.

>>11136762
Probably, my bad.

current song is a banger

2nd stage chill, get ready boys.

Wait, why do they do such a short second burn instead of just extending the original one?

Good orbit, only 1 more thing that could go wrong...

>>11136783
Orbital mechanics, you need to burn on opposite sides of the globe to get a circular orbit.

You can't expect to get approval to but up ~40 times the total number of active satellites in a single constellation without jumping though some hoops.
I'm still surprised they got approval at all.

see >>11135411

>>11135360
>I doubt that is the case but unless numbers are made public we wouldn't know.
Their launch prices are public and are significantly cheaper for a reused booster. And with Tesla's cashflow issues I doubt he can afford to float tens of millions of dollars per flight.

>>11136889
>Their launch prices are public and are significantly cheaper for a reused booster

Not really:

New: $62M
Reused: $50M

>>11136706
Doesn't matter because white.

>>11136914
~20% cheaper mate

>>11136914
But their prices for new boosters have also dropped, because they can recover the booster and reuse it.

>>11136889
>>11136914
They also be getting a better profit margin for the reused core flights. Once your prices are cheaper enough than your competitors, there's no point in lowering them more.

>>11138512
having a device fail during testing isn't a GOOD thing, but it's a better thing than having it fail after testing. SpaceX figured out what happened and have got a solution in place. This isn't a "back to formula" moment for the design. I think this thing will ultimately be a great little vehicle, that is swiftly rendered utterly irrelevant as Starship proceeds to ignite the full Space Renaissance.

>>11138902
I think it will be a good ride to LEO but I don't think it'll be made irrelevant because the government isn't going to use starship. If they did it would kill so many jobs in so many states the senate would never allow it.

>>11137775

>>11138957
>the government isn't going to use starship
If you had been paying attention, you would know that they don't have to use it. They already have plenty of things to do with it that don't involve the government, and cutting launch prices by two orders of magnitude means it doesn't need government-sized budgets to use it.

>>11138957
Economic forces are going to kill those government old space jobs. When it comes down to it, socialized space exploration isn't going to be viable in a future where entrepreneurial space colonization is building Industries in orbit. It will eventually be so much cheaper to use commercial infrastructure that people will be elected on platforms of reducing waste cost of government space programs by using private launch vehicles.

Bump. Did everyone shoot their whole week's space bolt yesterday or is something superb awesome going on somewhere else? Just tumbleweed and no UK anons to get my Michael Choo Choo Portillo reference

My point is manned Dragon will get ISS contracts, Starship won't.
Starship should however get plenty of payload contracts both government and private.

>>11140275
I hope NASA is able to make the switch from payloads and rockets to just payloads. They make great probes that do research with no foreseeable return on investment that private industry has no interest in.
