SpaceX sure knows how to make GSE slick. All of that grey superstructure is ugly

abort at T-85s!!!

HOLD

>>9430491
pfffff

ULA, give up already.

What happened? Someone hotboxing that mofo?

fuck they are using Fahrenheits
may lead to catastrophe

>>9430497
something wasn't right so they held and are going back through the pre-launch procedures, may still launch soon

radio silence for a while now

how hard is it to replace a launch pin?

>>9430593
It is telling them that the pin wasn't pulled when it was or something.

>>9430596
Fucken faulty relays

Haha wtf is this music

"the team is discussing an option forward"

>>9430605
damn that chess set looks disgusting

its gonna get scrubbed lads

>>9430616
>its gonna get scrubbed lads

this wait

so spacex launched NROL-76 on monday and it did something weird. coincidence? I think not. Also check out the patch for this one, that knight looks ready to deus vult some shit.

which Delta IV variant is this? small, medium, heavy?

I don't want to miss a launch, but I'd really hate to miss an anomaly.

please launch

Aw Come On Already!!!

>Update in the near future

Holy shit, I've been waiting a full hour for this shit.

>>9430640
its the Delta IV M+(5,2) variant. last flight of this variant, actually

>recommendation to lower yellow limit on temperature

>>9430659
the 5 means it has 5 meter payload area and the 2 means it uses 2 graphite-epoxy motor booster addons, pictured here.

>>9430666
you can see the two boosters on either side here

Is the rocket OK lads? Why is it paused at T Minus 4?

>>9430666
>a golf cart

the first stage of the delta IV uses the RS-68 engine, designed and manufactured by Aerojet Rocketdyne, a california based firm.

Now they are changing the temps settings for the alarms.

what's this 12-F business?

Space launches would be far more exciting if they just launched them without the safety checks.

>>9430695
lower limit acceptable launch temperature, sounded like

the second stage uses a RL10 engine, also built by Aerojet Rocketdyne

Well shit, my time is up.

sounds like they dont want to reveal the possible launch windows

>>9430714
According to spaceflightnow.com:

"The exact duration of today's launch window is not public, but the launch period could extend as late as 5:15 p.m. PST (8:15 p.m. EST; 0115 GMT)."

sunset is at about 5. Will make for a really nice show

>>9430707
Ah, I'm back. I see I missed nothing.

LAUNCH TEAM HAS WORKED THROUGH THE ISSUES

>event 30 and 31

what does it mean?????

>>9430759

>>9430764
swing arm pegs, those are the things that caused the abort earlier

this intro is pretty groovy

That video was so out of place. kek

Almost a 2 hour wait now.

>new time "4:05 pacific time"

so like 15-20ish mins or something?

What happens if they launch when the swing arms won't move?

>>9430790
If part of the rocket clips the swing arm, it will fuck up majorly and land on someone.

>>9430790
the whole earth gets launched into space.

>>9430794

So, this is what "edging" is like...

>>9430825
at this rate, even India will sneak in their next launch first!

(A PSLV is scheduled to go up at about 8PM PST)

will it be more pretty at night? sunset soon

>>9430917
That person is killed by it.

new T-0 at 4:59 PM PST, just during sunet

Odd, with all the delays, they've gained 10k more viewers.

>>9430929
>tfw the only reason they delayed was jealousy over Elon's giant space jellyfish

when is it going to launch?

>>9430935
Because since the stream started more people have become aware of the launch

>>9430942
Just before the turn of this hour.

>>9432751
was delayed this morning due to... another valve problem! This time in the helium pressurization ground system.

WTF am I watching?

>>9432776
Delta IV is launching a super secret payload into space. Dont ask too many questions.

>>9432780
It's not really that secret, it's just an imaging satellite for the military.

>>9432780

I'm assuming its some kind of weapons guidance system?

weather balloons. now look right here for me ...

31 minutes until launch apparently

Did something about the start of launch seem off?

I'm kind of nervous right now.

That looked bad.

WE DID IT BROS

>>9432921
>>9432922
SRB's are super funky.

>>9432921
The flames jumping up the bottom at ignition seemed scary, but it looks to be normal

>>9432921
yeah I thought it was about to explode on the launch pad

>>9432929
That always happens with the Delta IV.

All that hydrogen catching fire around the base of the rocket at ignition was pretty spoopy

we KSP graphics now

CIA spooks shutting down the live coverage

IT WAS A GUY TALKING

Do spy satellites really look like that or was that just a shitty placeholder?

*record scratch*

>completely normal launch

>>9432939
is it in orbit? did it fall into the ocean? That's classified, we can't tell you; blame the launch company!

Oh well. Congrats ULA. Looked funky, but sounds like it was nominal. But then, so was Zuma until maybe it wasn't.

>>9432943
>>9432944
could be worse. China drops exploding poisonous rocket stages onto their populated cities as normal procedure!

>>9432943
>>9432944

That's normal for the RS-68, it dumps hydrogen overboard before ignition to chill down the engine components, and that hydrogen catches fire once the engine ignites. The heat then scorches the insulating foam. This is one reason why the Ares 5 rocket was cancelled, it was going to require the RS-68 to be man-rated.

>>9432944
normal for a Delta IV

>>9432969
those burn marks looked more serious

Why fly with a flawless record platform when you can nickle and dime with spacex and have a 50% loss rate?

>>9432970
also normal for a Delta IV

>>9432945
>Being this buttmad over the latest SpaceX launch failure.

SpaceX fails.

ULA succeeds.

As is natural.

>>9432975
Neat, didn't know that
thanks anon

>>9432980
>t. Northrop Grummond

>>9432980
>>9432987
Based Matt

The explosion and charring of the bottom half spooked me, I thought the whole thing was going to explode.

>>9432994
they took the term "orbital burn" too literally

>>9432989
>>9432992
The payload is at the bottom on the Indian Ocean. The launch was a total failure no matter who's fault it was. Go back to /r/SpaceX you mongoloids.

>>9432992
Had spacex followed proper procedures, by having experience in doing any procedures, this wouldn't have happened.

They destroyed valuable payload and will pay the price one way or another.

It's only SpaceX's fault if the problem occurred before spacecraft separation. After that it's out of SpaceX's hands.

>tfw edged all night yesterday only to miss the climax today

God damn it.

>>9432997
>>9433003
Well, that assumes that the payload actually failed, which I'm pretty sure we don't have a proper confirmation of.
Pic only semi-related.

>>9433003
>>9432997
You miss understand. That part is the client's responsibility and most importantly, the mission was a success. This is a fake campaign in order to get people thinking the super secret spy sat failed, but it didn't.

we dont even know if the spacex launch was a failure or not, its all speculation and rumors. it could even be that the alphabet agency behind the spacex launch spread the rumors to throw off adversaries.

>>9433028
Assuming that the payload failed, which it probably did, the launch is still a total and complete failure. No payload in orbit means no success. It doesn't matter who or what was responsible. Total failure. No amount of analogies or arguments will change this fact.

>>9433035
>>9433038
Even during the height of the Cold War the US didn't fake a satellite failure to protect its secrecy. I see no reason why they would do it now.

>>9432980
launch went perfectly, N-G payload adapter and decoupler failed lol

>>9433046
>US didn't fake a satellite failure to protect its secrecy

lol I bet you think SDI ended in 1993 too.

>>9433047
This is not the first time a 3rd party part on a rocket has failed thus ruining the launch. Every time it has happened the launch was declared a complete failure, this is no different.

Does it really matter to you retards so much that your precious meme rocket has another blemish on its not spotless record?

>>9433009
this

>>9433054
Let me put it this way.

The launch vehicle did not fail. Everything that was in SpaceX's control went perfectly. Northrop-Grumman requested that not only they build their own payload adapter and decoupler, they also insisted that they themselves integrate the payload and close the faring, not SpaceX, because muh secret satellite. The Falcon 9 launched, staged, burned to orbit without a hitch. The payload then failed to decoupled because N-G didn't trust SpaceX's hardware and wanted to do it themselves. The satellite was therefore dead in the water and the order was given to deorbit the second stage with the payload still attached.

SpaceX literally did nothing wrong, except maybe by letting N-G do what they wanted.

>>9433071
We don't know what exactly went wrong. All we have is SpaceX saying that their rocket performed fine. To clear them of any wrongdoing at present is stupid. Wait for an official report to come out.

>>9433046
>Even during the height of the Cold War the US didn't fake a satellite failure to protect its secrecy. I see no reason why they would do it now.
You're wrong.
http://www.nbcnews.com/id/3077830/ns/technology_and_science-space/t/spy-satellites-rise-faked-fall/#.WljwbKinE-U

>>9433054
>Does it really matter to you retards so much that your precious meme rocket has another blemish on its not spotless record?
What I care about is knowing whether the launch actually was a failure or not. Sure, I'd prefer if it actually was a success, but that's not why I doubt the assertions of failure, it's because of the secrecy of the mission and the statements that don't quite add up.

>>9433076
I agree that we don't know enough. However, if SpaceX is saying the rocket performed perfectly, do we have any reason not to trust them? Especially when it would be a disaster for them to outright lie about their launch vehicle's performance this way.

>>9433077
That was during the Cold War. Times are different now. If it is in orbit, it will be seen by ground observers in about a week.

>>9433076
It's all super sekrit, so I doubt we'll ever get a detailed report on the problem.
If SpaceX says everything performed right on their end I believe them.

>>9433081
Because it was said very soon after launch when the investigation hadn't been completed. All the launch data needs to be combed through so they could've easily jumped jumped the gun on declaring that the rocket performed fine. They wouldn't be the first ones to do so.

>>9433097
I mean, if the second stage engine shut down on time and tracking showed it was in the correct parking orbit, then the rocket has performed perfectly.
Usually the job of SpaceX also includes payload deployment, but in this case someone else had built the payload adapter and fitted the payload themselves, so it was pretty much their show at that point.
If SpaceX put something into space using their regular hardware, built in house, and the payload failed to separate, then yeah that's definitely SapceX's fault.
