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"

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?

I guess it'll ram the back of it. Even if the autopilot cut the engines the rocket keep it's velocity.

Damn, Elon is 2 for 2 on shitty "autopilot" designs.

That's one hour from now, correct?

Wait never mind that's 3 hours, I'm retarded

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.

Are you dumb m8?

yes.

Landing attempt from last time. I hope to see something similar

Faked, they played the launch footage in reverse

Kek
Some people actually believe that

if it was in reverse the exhaust would be flowing back in to the rocket, not outward

when will musk stop selling us bullshit?

>what is adobe after effect

plz

So much this
good goy

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

don't they launch everything from florida?

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

It's a platform on the sea.

5:40pm (local time in florida) is considred night?

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.

Fucking kek

What do you suggest it should do? Try to flip over?

>Fucking kek
Is this funny to you?
Do you think this is a fucking joke?

give me phone number I'll send you text

1 hour to go

sooooon

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

fucking boats

Well there's not official infos about a boat for now

anyone know how to watch a youtube livestream in something like mpv

with youtube-dl I think

When 's the big test with the big dildo not this one

Type "mpv ytlink"
You've to wait for the streams to be up tho, it won't work until then

>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

Maybe the mpv dev will add a countdown for planned livestream as YouTube do

When does it start?

SoonTM

Whenever Elon's attack helicopter gets the job done.

supposedly nao, but the webcasts aren't up

The launch window is 2 hours long, they delayed the launch into this timeframe

>he doesn't know alt codes

0153 is one of my most used to be honest.

youtube.com/watch?v=zBYC4f79iXc
>Please stand by.

is there an another stream? could it just be that the youtube one isn't workting?

where is the spacecraft going?

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?

to spaaaaaaaace

uranus

Supersynchronous orbit iirc.

Those are the official stream from spacex. There's maybe one on nasaTV tho
It's launched one a super-synchronous geotranfer orbit. The satellite will boost itself on the good orbit on its own.

78.5° East

nice trips, and pls tell me that again but in not super complex scientific talk

to infinity and beyond

Geostationary transfert orbit*
fml

>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

how do you know? the stream is not live

>how much fuel does it take to stay in orbit?
stationkeeping at high, geosynchronous orbits are cheap

most (90%+) of a satellite's launch mass is fuel for orbital insertion and stationkeeping

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

Couple streams from the ground

periscope.tv/DestinationAdventure/
periscope.tv/murphypak/

Sauce or you're a faggot

it was just a prank bro

Same™

The Technical webcast says it's delayed.

It doesn't

>murphypak
>supergeo...symphmphs. seven fourty.
Lass sure knows her stuff.

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

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

the same amount of fuel in the final payload will give more delta-v than in the booster stage, though there's a limit

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.

It also depends on the type of fuel tho.

yeah, hypergolic fuels tend to be less efficient

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

fml

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).

>how much fuel does it take to stay in orbit?
none

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

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.

>>how much fuel does it take to stay in orbit?
>none
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.

Only 10-20? How many sats are we launching per year?

ULA shill detected. Too bad you currently depend on SpaceX to lift your colander condoms into orbit.
space.com/32998-bigelow-module-on-space-station-fails-to-deploy-on-first-try-video.html

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.

not as much as the sailboat blasting through LEO that is the ISS

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.

~30 to LEO/year
~4 to GEO/year
