SpaceX launch thread
SpaceX will launch the Thaicom-8 satellite on top of a falcon 9 rocket.
Probable launch time: 21h40 UTC (convert to your time zone fag)
It's the 5th launch of the year and they will attempt to land the first stage on their drone ship "Of Course I Still Love You"

3 hours to go, ask questions I'll answer if I can
If it encounters a stalled vehicle in the flightpath, will the rocket's autopilot bring everything to a halt or just ram into the back of it?
>>54754351
I guess it'll ram the back of it. Even if the autopilot cut the engines the rocket keep it's velocity.
>>54754378
Damn, Elon is 2 for 2 on shitty "autopilot" designs.
That's one hour from now, correct?
>>54754457
Wait never mind that's 3 hours, I'm retarded
>>54754457
No it should be 3 hours
Who cares about some rocket? It won't affect any of us directly, unlike the new EVGA GTX 1080.
>>54754525
Are you dumb m8?
>>54754533
yes.
Landing attempt from last time. I hope to see something similar

Faked, they played the launch footage in reverse
>>54754719
Kek
Some people actually believe that
>>54754719
if it was in reverse the exhaust would be flowing back in to the rocket, not outward

So much this
>>54754667
good goy
>>54754313
lets see if it gor s into theat big old blue sky up there real fuckin far away. shit. i want to see it and will eatch the daht! dha dah dah dah dah dah!!!!
It'll be a night launch so we won't see shit for the landing
>>54754931
don't they launch everything from florida?
>>54755069
They can't launch whenever and whereever they want. The satellites needs to go in a specific orbit so they will launch from cap Canaveral at 21h40
I live in Sarasota, almost directly across the state from CC
maybe I'll be able to see it going through the air
>>54754769
It's a platform on the sea.
>>54754931
5:40pm (local time in florida) is considred night?
>>54755463
Oh yes you're right I'm dumb
Fuck, too late for me here in Western Europe. Will have to rewatch tomorrow
Can someone please PM me if it crashes? I have to go to my wife's son's basket ball game.
>>54755749
Fucking kek
>>54754440
What do you suggest it should do? Try to flip over?
>>54755769
>Fucking kek
Is this funny to you?
Do you think this is a fucking joke?
>>54755749
give me phone number I'll send you text
1 hour to go
sooooon
https://twitter.com/aallan/status/735944119533506560 goddammit boat
The launch window is 2 hours long and they said they'll delay the launch into the window so it'll not launch at 21h40 but later
>>54756617
>>54756648
fucking boats
>>54756672
Well there's not official infos about a boat for now
anyone know how to watch a youtube livestream in something like mpv
>>54756716
with youtube-dl I think
When 's the big test with the big dildo not this one
>>54756716
Type "mpv https://ytlink"
You've to wait for the streams to be up tho, it won't work until then
>>54756754
>You've to wait for the streams to be up tho, it won't work until then
fug, it'd be nice if it had a stream setting
>>54756779
Maybe the mpv dev will add a countdown for planned livestream as YouTube do
When does it start?
>>54756840
SoonTM
>>54756840
Whenever Elon's attack helicopter gets the job done.
>>54756840
supposedly nao, but the webcasts aren't up
>>54756840
The launch window is 2 hours long, they delayed the launch into this timeframe
>>54756868

>Please stand by.
is there an another stream? could it just be that the youtube one isn't workting?
where is the spacecraft going?
>>54756617
This shit always happens when I actually have the time to watch and they have to scrub that shit for the day then the next time I hear about it they already launched and finished up. I should just stop trying to watch this shit.
10 minutes have passed, whats happening?
>>54756951
to spaaaaaaaace
>>54756951
uranus
>>54756951
Supersynchronous orbit iirc.
>>54756949
Those are the official stream from spacex. There's maybe one on nasaTV tho
>>54756951
It's launched one a super-synchronous geotranfer orbit. The satellite will boost itself on the good orbit on its own.
>>54756951
78.5° East
>>54756999
nice trips, and pls tell me that again but in not super complex scientific talk
>>54756951

>>54756999
>The satellite will boost itself
seems pretty stupid? how much fuel does it take to stay in orbit? is the rocket to big not to smash anything else?
Please can someone answer my question
IT LAUNCHED
>>54757033
how do you know? the stream is not live
>>54757027
>how much fuel does it take to stay in orbit?
stationkeeping at high, geosynchronous orbits are cheap
>>54757027
most (90%+) of a satellite's launch mass is fuel for orbital insertion and stationkeeping
>>54757027
No the rocket doesn't have enough fuel to boost the satellite all the way up
It's easier to let the satellite boost itself and once the satellite is on the right path it doesn't take that much fuel to boost it on the good orbit

>>54756918
Same™
The Technical webcast says it's delayed.
>>54757112
It doesn't
>>54757094
>murphypak
>supergeo...symphmphs. seven fourty.
Lass sure knows her stuff.
>>54757069
Isn't is partly because launches aren't perfect so it's better to give the payload the fuel for final placement rather than load more fuel onto the rocket?
I need to get Kerbal Space Program again.
Delayed for another 1:33
1:33Hr to go
>>54757173
The rocket fuel can't stay for long in the tanks, it's liquid oxygen.
The satellite use hypergolic fuel, aka fuel that doesn't boil up
>>54757173
the same amount of fuel in the final payload will give more delta-v than in the booster stage, though there's a limit
>>54757173
One thing is that it takes a relatively long time to coast to the orbital insertion point, and most launchers aren't designed to function that long. Also most launcher motors can't be restarted that often.
Whereas the payload motors by necessity (for stationkeeping) use hypergolic (i.e. self-starting) fuel and are design for decades of functioning.
>>54757210
It also depends on the type of fuel tho.
>>54757228
yeah, hypergolic fuels tend to be less efficient
>>54757210
>>54757228
yeah, hypergolic fuel used for stationkeeping typically has fairly low Isp
however all this is changing with electric propulsion becoming more and more the norm for payloads, with the drawback that it takes months for GEO insertion
>>54757188
>>54757193
fml
>>54757173
Indeed. When you need moar Δv, you can arrive to a point where it's cheaper to put it into a later stage. Dragging a mostly empty second stage into geosynchronous orbit is far more expensive than expanding the third stage (which is in this case the payload).
>>54757027
>how much fuel does it take to stay in orbit?
none
>>54757273
Wrong. It's not KSP faggot you need to correct the orbit over long period of time.
A satellite has a lifespan of 10 to 20 years depending on the design
>>54757273
In theory, if the Earth were a perfect sphere and there was no moon, sure.
In reality, for GEO it's some 40-50 m/s of delta-V per year.
I hope it blows up.'

There's still a faint wisp of an atmosphere up there, light but not negligible. Also, you have to make corrections to cancel perturbations by the rest of the solar system.
>>54757287
Only 10-20? How many sats are we launching per year?
>>54757313
ULA shill detected. Too bad you currently depend on SpaceX to lift your colander condoms into orbit.
http://www.space.com/32998-bigelow-module-on-space-station-fails-to-deploy-on-first-try-video.html
>>54757330
Several per month, not all of those are commsats for GEO but still quite a few.
For SpaceX over half the launches are to GTO and they're doing 1-2 per month nowadays and rising.
>>54757273
not as much as the sailboat blasting through LEO that is the ISS
>>54757330
A lot, there's a shitton of satellite in orbit but space is so fucking big the only thing that matters are the debrits left in orbit that can cause collisions.
Satellites in GEO have close to no chance of colliding.
>>54757330
~30 to LEO/year
~4 to GEO/year
>see thread at noon
>turn on netflix
>5 hours later
>it got delayed
>>54757378
[citation needed]
SpaceX alone is planning to launch 12 commsats into GTO this year (already launched 2, and todays is the next), and then there's all the other launch services.
>>54757350
>ULA launch failures: 0
>SpaceX launch failures:4
ULA wins again fuccboi
>>54757421
Whoops, I was looking at the numbers for the USA alone
Worldwide its like 100-150 LEO and 25-30 GEO
How many of you faggots are at HQ? I quit in January, but good luck and God speed faggots.
>>54757475
so that means on average a rocket launch every two days, pretty amazing
>>54757521
Why did you quit?
I'd send my resume if they didn't require murrican citizenship to do anything interesting.

Should we count the failures of Boeing and Lockheed-Martin before 2006?
>>54757546
probably because he couldn't handle elon's 9 inch cock sliding up his boipussy

It's a nice website, there's an API you can use to get upcomming launches

Don't talk to me or my rockets ever again.
>>54757526
For LEO there are often multiple satellites deployed per launch

So after the delay it will be 4 minutes before the end of the launch window, is it OK to launch this late?
>>54757699
It's in the launch window so yes
>>54757699
>Is it safe to launch within the launch window?
>>54757729
Not him but he may be referring to the prelaunch procedures leaving enough time.
>>54757699
It'll be a tight fit, but it may just work.
>>54757699
As long as it is within those 4 minutes, if they miss it then the next window is the same time tomorrow.
>>54757589
nice website indeed, thanks
Is there a way to limit the list to spacex launches, without using the API?
Aaaand it's kicked into tomorrow.
>>54757814
I don't know if you can do that without the API, the API return json data tho so you can make a webpage to display the infos
Delayed to tomorrow. FML.
REEEEEEEEEEEEEE
I've a fucking final in 5 hours I stayed up just for this shit fucking shit
>>54757903
Life is cruel. Good luck tomorrow, both you and SpaceX.
Well I'll make a thread tomorrow with maybe pics about the orbits and deltaV and other shit so we won't have to much questions

All rockets have a self destruct button as far as I am aware. The range safety officer or whatever they call the job should be sitting by a button and can abort the launch at any time it becomes too unsafe to continue.
>>54759084
Would you rather have a rocket flying towards you or a gigantic fireball of molten metal and burning rocket fuel flying towards you?
>>54759151
The ultimate end result would be the same: A destroyed rocket and aircraft.
so did it explode or what
