Dare I say... BASED.

>>11282358
Are you gonna do launch threads for all 24 Starlink launches this year and the dozen or more non-Starlink ones?

>>11282710
of course.

>>11282767
Looking forward to the bi-weekly or less launch threads then.

>>11282785
with this same image, since SpaceX apparently doesn't want to even put a different number on the Starlink patch for each launch

Are you guys ready for Starlink to be the largest commsat fleet by the end of the night?

>>11282811
2nd will be Planet Labs? WP says they have 150 active but that's a couple years old

What's the word on the fairings from the last launch, and the plan for this set?

>>11282837
I'd heard they tried catching them but didn't hear if they did or not last time.

>>11282837
fairings from the last launch missed. This launch, catching one with Ms. Tree and fishing the other one out of the water with one of the SpaceX support vessels GO-something

>>11282811
Yes, but I'm also dreading the astronomers complaining that one modified sat is not dim enough. And the usual "Elon musk is destroying our skies" articles.

Isn't the launch like in an hour or so?

>>11282861

No, they're going to draw in more diversity hires that will delay the progression of SpaceX''s goals with their incompetence.

>>11283063
What about the very large telescopes based on the mountains? SpaceX satellites have ruined some astronomic observations already. This will only get worse over time.

NIGGER WHAT HAVE YOU DONE

>>11283081
there has already been the first tweet. and they played CSGO over the Tintin test satellites.

>>11283071
starlink only effects hobbyist astronomers who observe a the sky from and for a very specific thing. literally just ignore their whining. besides, starship will be able to put lots of astronomy related craft in orbit for cheap so let them fund it with starlink

>>11283091
Ironic given his background.

>>11283071
You realize that astronomers constantly have to deal with satellites and it's a very trivial event to remove them from their data and images, right?

The only people upset about Starlink are idiots who once used a telescope pretending to be astronomers.

is it just me or is the countdown irregular?

You would be hard pressed to find anyone who could do a worse job than the current hosts. Not only are they bland as hell, they misspeak all the time. SpaceX is the company for autists, they need one of their own as a host.

>>11283218
I wonder about this too, judging by the initial images people were posting the satellites ended up with some inconsistent spacing, maybe they've evened out since then but I haven't checked. I'd presume if the spacing stayed inconsistent, they'd attempt to space them out better on the second run. I'd like more info in any case, if anyone has any, I'm just shooting in the dark here.

So are they
Hukhukhuk
I’d like to know more about the system too since the one on the Rocketlab’s Electron kinda destroyed my friends cubesat, it was too violent (after surviving launch and rumble tests prior) and they likely broke due to the shotgun release.

>>11283267
LOL OH

>>11283266
Everything is nominal. Calm down.

>>11283233
it will be a gross deployment, dunno what that anon is talking about.
The spacing is due to how they orbit raise, not the deploy. the variance in the 'orbits' of each satellite after deploy isn't significant

>>11283270

>>11283256

>>11283286
>Elon is Q

Is there going to be a "Starlink flare tracker" soon?

Cūcksheds, cubesats, tiny houses...what’s their plan?

>>11283290
I'm sure someone is working on it. I think Elon said he would design all future sats to be less reflective

>>11283284
it was something like that.
its a bit lame not having any footage of the deployment exactly for these reasons, i hope Rocketlab up their camera game much as spacex has done from the start. Mate worked tirelessly on that sat for about 18 months solid. Already working on the next one though. Positive thoughts. Space isnt easy.

>>11283291
Every ainternet user will be allocated 1 shitpost per month. Use it wisely.

>>11283292
>I think Elon said he would design all future sats to be less reflective
Aww. I wanted to see them.

just got here, when do they deploy the satellites?

>>11283290
Starlink sats don't flare like Iridium did

>>11283290
there are multiple.

If it broke on an Electron, the gentlest ride to orbit available, then it wasn't built sturdy enough

>>11283297
Nig-

about time

>passes over Yemen

I wonder if as the starlink satellite density increases we'll get to keep live communication with launch vehicles for longer. And I was about to write how it would be neat to see some kind of visualization of where the other sats are relative to the launch stages, but I realized one of the hosts mentioned that the position data should be available to astronomers, assuming orbiting trajectories and depending on how much info they release it shouldn't be too hard to make one myself.

>>11283316
FCK THAT’S OMAN

>>11283318
http://stuffin.space

>>11283310
I can see what you are trying to say, but did you miss the bit where i told you it passed the rumble tests, and launch, but their ejector of the cubesats smashed them into each other? It was built to the standard (very strict) requirements. Ok. Carry on.

>>11283183
Someone's getting fired for that.

>Elon, we can adjust the final orbit with RCS
>Fuck it, do a 1 second burn to show off our Merlin capability

I'm late but here to dance

>>11283318
I wonder whether we'll end up with telescopes built of constellations of adapted Starlinks. I mean think about it - if you keep the platform the same size, weight etc but swap in sensors for telecoms hardware you have a constellation that can be delivered on standard Starlink launch. Stack the imagery to get good resolution.

>>11283353
it was 140 m/s or so, and Falcon 9 uses cold gas RCS on both stages

>>11283304
Shit, it will be flying right over the mideast-east of the US. Too bad about all this fucking cloud shit all over the sky.

Any fairing news?

>>11283366
Won't see anything in the middle of the night. It'll still in a close pack for a few days so better luck during sunset or sunrise.

incoming

>>11283369
It's been a fair while since we got an update

>>11283356
How fast are the sats moving? I wonder how much exposure times the individual sensors would have before being occluded by the Earth during their orbits. It would be neat to see some kind of progressive render of nearby celestial bodies over time though!

>>11283379
Around 17,000 MPH

>>11283379
Right now it is at, 28,805km/s (17,898.597mph)

TAZMANIA HACKED THE STARLINK

>>11283374

>tfw when everything goes completely and utterly nominal

>>11283422
Actually sweety, the fairings didn't get caught. Yikes.

>>11283426
They don't have a nominal for that though.

>>11283301
I saw one once before I really knew about it. Glad I saw it when I could though.
It was at a park with astronomers. They were all keen on seeing it. Funny.

>>11283404
they just use the equitorial bulge (owo) to do precession
they gain a degree a day or something dumb like that

>>11283379
Hmm good point. I was thinking sensor would be pointing outward though toward space. You could fly them in a grid and use photogrammetry to rectify the sensor offset then stack for resolution, and with big enough spacing you could use parallax to derive 3d. And with so many sensors each one can be cheap COTS not stupid expensive custom

>>11283415
Nah, catching fairings dry is just a bonus at this point. If they catch it, faster reuse. If not, just fish it out of the sea and do some refurbishment before reuse.

>>11283407
Why do that look so different from the other star link satellites?

>>11283415
>>11283410
They've been at this a while and have no real improvement, I suspect its simply too hard. But yes I expect the solution is RCS on the fairings but idk if they will bother with that when bfr is right around the corner.

>>11283274
Does the spacing sort of even out? My autism demands it.

>>11283473
they've all looked like that
>>11283491
once they're in the deployment orbits in a few months it'll even out

>>11283502

>>11284781
no

>>11284782
watch in this area
sure looks like lightning to me, of course I could be wrong.

>>11284794
looks like something in the foreground is being illuminated by the second stage (that's where the light is coming from, right?)

>>11284799
>that's where the light is coming from, right?
I don't think so, watch that area in the webm, it looks like a lightning storm in the clouds to me.
it happens throughout the entire clip, even after the 2nd stage has stopped lighting the 1st stage.

>>11283265
Surprisingly, asat kinetic weapons can send fragments to higher orbits, even if the target was in LEO and the interceptor was suborbital. For example for the Indian ASAT test: https://twitter.com/marco_langbroek/status/1124218799815831552?lang=en
Of course the periapsis can't be higher than the original orbit, but some of the debris for this test are still there

>>11284868
the perigee will still be low in the atmosphere
any new orbit MUST pass through the location where the orbit was changed

Woohoo!

>>11284781
Yes, that's lightning.

>>11286938
was there lightning in central florida at 9:30 pm two days ago?

>>11287152
That webm >>11284519 was one and a half years ago, Anon.

I'm pretty sure that webm is from a different launch.
