when hop bros?
>>13075116excuse me sir this is a starlink launch thread, please leave your hop at the door
Shouldn't Musk be forced to pay for more telescopes? Why did the US just hand him our skies for free? Why is he even allowed to pollute non US skies with his scam? You will never see a sky like pic related again.
>>13075116No hop today. Only Starlink.
Fuck off, (you)
>>13075178(You) should kill yourself
>>13075232>>13075243If China or Russia had decided to just launch a constellation like that the US would have intervened and you know it.
We said fuck off and die anon
>>13075178Fuck off lenslet.
>>13075048Not science. Go to /g/./g/ is for technology
>>13075418how nu r yu
>>13075178>>13075311THIS. muricans are a bunch of hypocrites.
>>13075048>Launch vehicle: SpaceX Falcon 9 with first stage B1049.9So this will be the second booster to make a 9th flight and hopefully 9th landing?Can't wait for that #10.
>>13075178SpaceX has modified their sats to be drastically less reflective, and almost undetectable when fully in orbit.Your poor attempt at trolling may have held some merit almost a year ago when Starlink first started getting launched, but even astronomers are happy with the darker revisions. Hence why you don't hear many people crying about it anymore.
>>1307558210 is just around the corner hopefully
/sfg/ is abysmal today
>>13075048>Starlink 25 today>9th launch (and landing?) of this booster.Imagine working on building boosters at SpaceX, and suddenly, there's nothing to do.
>>13075178Bullshit.Even astronomers know it.They just don't like Elon Musk.If they were smart, they would ask Musk to send a billion dumb ass telescopes into space.
>>13075116ScrubX at it again.wait for super-heavy and how many months it wil spend on the pad before blowing up.Remember, Musk said 2024 on Mars.
>>13075656for real. comfy starlink launch thread is our only refuge
one hour to go!>>13075680meanwhile the 2nd stage production line is feeling that gif from Airplane! with the sweat
>>13075734>2nd stage production lineGuess there's still that to do.Now I hope a stage doesn't land from time to time.You don't want to fire people that can build them.
>>13075743>Guess there's still that to do.Don't forget the fairing cleaners, now that they're not catching them in big nets anymore.
>>13075750Yeah, I gues by this point, SpaceX R&D is all in on Starship, even for LEO launches.
>>13075778musk mentioned that in the SN1 days about 5% of spacex was working on SS. He said that once crew dragon engineering was done, a lot of staff would be shifted over to SS. Wonder what the % is now
>>13075849that render is sorta funny right now
lunch auto-benis start
After this 10/13 SpaceX launches this year will be Starlink. 11/13 will have had Starlinks onboard (transporter-1)lol
>>13075907Elon can't keep getting away with it
music has started
M U S I C>>13075656Boardfag just have just ended his latest 3-day ban.
SpaceX has the best tunes
daylight launch for once jeez
Here we go, stream is up!
>Be Arianespace.>But look, we Ariane6!>It's of cost barely less than Ariane5.Why do they try, when all they're gonna get is gobernment contracts?
I would love if Elon was the narrator for one of these starlink launches. Don't even announce it, just one day the stream starts and it's Elon and Insprucker in the mic
>Star Wars Day
>Starlink dish visible on the shipneat
>>13076041I think he may have been on the 'net for F1 launches
>>13076043Considering how cringe that announcement could have been, Siva handled it well. Just mentioned it once and moved on
Does only one fairing half have a metal tip? It bothers me.
'contracted recovery vessel' just doesn't roll off the tongue as well
Okay Falcon is flying all the damn time now. What is the average cadence for Falcon these days? 2 a month??
>>13076054Average is 4/month this year.
>>13076050I think both sides
>>13075116at least we have the starlinksgood old F9 rocket
>>13076051What happened to ms tree and ms chief?
>>13076066They let the leases lapse and got a new boat.
>>13076037cool, never seen the standalone toilet witch pepe, saved
>>13076055That is actually insane
>>13076066They gave up on catching fairings.
>>13076066salty water is less of an issue than a fucking hueg net.This launch is using a twice-flown fairing half btw
>>13076070Remember when NASA thought they could get that kind of cadence out of Shittle?
>>13076066>>13076072they moved the fairing vents to the "side" of the fairing and make water landings and fish them out.
>>13076078>Fairings become autonomous drone ships that sail back to KSC
we are GO
>100k people watching nth Starlink missionDamn
>>13076093>SpaceX's only reason for putting Starlinks in orbit is to increase viewer count on their YouTube Channel for easy monetization
Lol that was anticlimactic, it just sort of lit and started moving
real good audio for a few seconds there
cool view of the space coast!
>>13076056what's up with the little flappy pockets? seems like they'd tear off.
>>13076105Not so fast.
>>13076102Yeah, that's kinda what happens
Wow awesome shot
>>13076102That is what rockets do.
>>13076110those are actually just straight holes to the inside. Prevents pressure difference problems
EVERYTHING IS NORMAL
>>13076093they've racked up quite a bit of subscribers ever since the starship test program began, I believe it's 5x'd. >>13076102that's what rockets do
>onboard camera for most of the flight so far, despite it not being necessaryneat, love seeing them do different camera views when they have so many flights
ASTRONOMERS SEETHING AGAIN
Really nice view of Florida today
Jeez I thought something was going wrong with the liftoff. Seemed kinda slow.
How manyeth starlink mission is this?and how manyeth mission is this for the booster?
>>13076112>>13076116>>13076119It was just weird because there wasn't much rocket audio being pumped through the live feed. It seemed quiet. I hate the NASA launch america streams but they DO have way more audio. You can hear the rocket hissing and screaming and once launch starts you can hear all the engines fire up
>>13076133Like 2510th launch for this booster
>>13076132starlink launches are actually some of the heaviest recoverable F9 launches out there. 15.6 tons. For comparison a Crew dragon with trunk is ~13 tons. (metric)
>>13076151Note that on DM-2 the total payload was around 18 tons due to food rations
Do you know when SN15 starts?
>>13076164It was scrubbed today. Next chance is Thursday afaik.
that last second divert is scary
LANDING LAGS LINED UP WITH SPACE "X" LOGO WTF
Dead center, nice
Ooof, that looked like a hot landing, but nailed it.
That landing looked really close to missing the pad
the landing never gets old, spacex progress really keeps me going
That landing black out!
The lads did it once again!
dead fucking center
>Keep launching Starlinks>Internet live feed gets worse
At this rate, those booster will be flying a decade.
>>13076180it aims for a point next to the barge initially, then scoots over right at the end, so if something goes wrong it hits the water not the barge
>>13076189literally flawless. What the fuck spacex
space ice rat time
>>13076194>BargeThis triggers the Elon
>>13076179>>13076180don’t quote me on this, but I think they aim away from the ship initially, then hover back over once falcon 9 is sure it can land safely
APP UPDATE AVAILABLE
>>13076180Yeah I thought it was going to land right beside the ship at first, but then it got a bullseye so I guess not.
>app update available
>>13076180?????The booster is off-course intentionally and only corrects at the last moment. If something goes wrong with the booster, it wont hit the droneship.
>>13076110>what's up with the little flappy pockets? seems like they'd tear off.They're meant to tear off.
>>13076192>I have no idea how a satellite uplink in the middle of the sea works even though I have it explained to me a million times in every launch thread ever.>>13076200It doesn't do hover. It comes sliding in.
Looked as if there was smoke coming from the engines before landing burn, but I guess it was nothing
>App Update AvailableWhy doesn't SpaceX update their app?
not gonna lie, my heart skipped a beat right here
>>13076214Because you don't update 5 minutes before you go on air if it werks.
>>13076194>>13076200They do, but only before the engine lights, after that they aim it at the barge
man I can't FUCKING wait till the Bezos mom boat will get smashed up by the first few NG attempts
>>13076212Sorry that’s what I meant, falcon 9 can’t hover due to the t/w ratio
>>13076177>>13076189I was thinking they had repainted the X but that was just the legs. Yeah, they stopped repainting it because they kept nailing it.
>>13076180Additionally to what others said, the 1st stage still has some horizontal velocity when starting the landing burn, so it's normal the booster is not aligned with the droneship
>>13076230...New Glenn actualy exists?
>>13076226>>13076194also on land they programmed in various buildings. so even if it goes off course with limited control somehow, it will do its darnedest to not blow up the VAB
>>13076234This drone ship has a freshly painted X on it, saw it on the drone camera before the landing
>>13076234They repainted them recently
>>13076232Look at the fucking trajectory some time, brainlet. Of course it comes sliding in.
>>13076240a single test article
It's gonna fly over my house, lol.A shame it's still daylight over here.
>>13076254Good chance you can spot it in one of the next few passes around sunset
Wow so B1049 is their oldest currently active Falcon 9. She first flew in September of 2018.
I was skeptical about the super heavy catching plan Elon proposed but after seeing almost every F9 hit dead center on the drone ship it doesn't seem as crazy anymore
>>13076282I was thinking the same thing.
>>13076282From what I understand, all falcons are connected to a main computer which learns from each and every landing. The first landing attempts were shit but as they tried it more and more the computer was able to compensate for new parameters. That's why it gets dead center these days. Again I'm not completely certain but I'm pretty sure this is how they do it, so I suspect SH will be the same once they try and start landing it
What are you going to drink/eat/whatever when an F9 makes its tenth landing and stubbert0e is btfo?
>>13076151another day older deeper in debt
>>13076252Seriously? I find that hard to believe.
>>13076151The limit for reuse on a Falcon 9 is 16 tons. Starlinks push the boundary
imagine if musk borrows the whole catching a rocket with a helicopter idea from RL, but for SH? Imagine a dozen full sized chinooks with a special apparatus plucking a gigantic rocket out of the sky
>>13076301The tears of SpaceX/Elon Musk haters and old space.
some fuonky music rn
>>13076298Not likely to be live just because of the comm link problem, but still possible if they upload the accumulated neural net before launch.>>13076252>a single test articleSo BN1-tier? Do they even have enough BE-4s that won't go engine-rich yet?
>>13076304>>13076326It’s not even a manufacturing pathfinder it’s just a mock-up. BN1 was closer to flight hardware. Also apparently on NSF it was leaked that less than 10 BE4 engines have been built
>>13076330~10 engines produced, and still having issues. ULA made a big mistake going with the BE-4 for Vulcan imo
>>13076340Yep. Blue Kees getting JUSTed
>>13076330bob even admitted they only aspirationally plan to build 40 in 2022 lol
>>13076305You made my day, anon. Thanks.
>>13076282why don't they just land on a giant magnet?
the virgin leaves thread after landing vs the chad waits till deploy
Guys. My memory is failing.When was the last brand new f9 booster?
>>13076345>>13076340Hahaha that’s so bad holy shit.
>>13076359Who wants to leave anyway? Free music to enhance comfy browsing.>>130763309 years in development and they still have yet to produce a MOCKUP!? Whew.
>>13076367oh shit b10something, good question. hardly any are spotted leaving hawthorn nowadays; all of the refurb is done local at KSC
>>13076378Blue literally chose the most expensive way of building stages (isogrid). They brought this upon themselves. >”Bunch of new info here. The BE-3U is an open expander. both stages use aluminum isogrid tanks, so that big CFRP winder must be for interstages and fairings.”
>>13076474tomorrow, today's attempt was scrubbed
>>13076486I assume most of those 1 or 2 flight cores are reserved for government payloads?
Cool, another great deployment. Also, RIP stream.
>>13075680I'd imagine that the people building Merlins would have shifted to the Raptor line.
>>13076512Yeah the crew 2 booster also flew crew 1 iirc
>>13076199>Big Ass Reusable Grin Enhancer
>>13076541Demo-2, not crew 1
