no 1st stage landing this time, since the drone ship is out of duty currency as it gets ready for FH.

extra sooty this time.

HAHAHAHAH

Americans are so broke you can't even afford to paint fucking rockets lmao

Here's the current weather forecast.

it is painted you dunce, they just don't bother to wash it off after each flight. I think it looks neat. An "aliens" type future of rugged and dirty spaceships is cooler than a sterile one don't you think?

will it blend?

>can't really contribute man power to alliance
>can pay for mil comm satellite

not a bad way to fulfill your nato obligations

Scrubbed for the day. Replacing 2nd stage sensor

no you don't paint rockets idiot, why would they add 1000 lbs of unnecessary paint

But you do paint them you mong

no you don't retard

Not him but actualy some rockets are "painted" with special "paint" for white colour to reduce boiloff. Check out first STS launches.

and then they stopped painting the tank because its pointless.

Because STS launches were more expansive than expected and they were doing everything they could to reduce mass.

>The first two, used for STS-1 and STS-2, were painted white to protect the tanks from ultraviolet light during the extended time that the shuttle spends on the launch pad prior to launch.

According to wikipedia it was not painted white to insulate it

pretty

Because hydrolox rockets with outside isolation are not painted you have the isolation in place but rockets without deep cryo are painted because simple layer of paint decreases the thermal transfer and protects the metal from outside weather.
Rockets from R7 to Falcon 9 and Angara are painted

How's the weather today?

looks like 10-20% chance of weather violation

You know, if this blows up, they'll ground Falcon Heavy.

If this blows up, they'll ground a lot more than Falcon Heavy.

2 hr to go

GO for prop load

>fly, you little fuck

livestream funky Elon beats has started

Stream starting

Stream proper starting, no Insprucker tho

6 minutes to launch

odds = blows up
evens = successful launch

So this is the power of the illusive hacker, Veeky Forums... Whoa...

It's in the OP, dumbass.

30 seconds

why does the booster have the legs if they're not recovering it?

Are you sure those aren't just the shadows where the soot didn't go? Or maybe they're empty fairings.

might as well get testing data. Rumor is they are testing extra aerobraking by deploying them earlier

SES got more dishes than the NSA

theyre hovering it over the sea in a simulated landing
they're basically trashing all the Block 3/4 boosters since Block 5 makes them obselete.

no, it does have legs and gridfins. It'll "land", but sink.

Millennium Falcon

Is this an used booster?

yes, as the OP said it previously flew NROL 76. 6th reuse to date

>theyre hovering it over the sea in a simulated landing
so they are just littering the ocean full of garbage? cunts!

stage 1 has splashed down

I wonder how much rocket trash there's under the sea.

S1 rip in pieces

a lot. There is a "rocket graveyard" as well where most of it ends up

F

legs deployed really early. So they definitely tested a new landing burn profile

also, just 10 seconds of landing burn. probably full-on 3 engine all the way.

maybe not, if the early leg deployment helped slow it down.

Ah shit, i've missed it.
No booster recovery?

>Livestream is also now the thread theme
YGYL boys

Yes, from the mission with the best footage of launch and landing so far, NROL-76: youtube.com/watch?v=EzQpkQ1etdA
It's ground footage almost all the way through.

Quite a bit. Bezos even had a team recover two F-1 engines a couple years back.

No, they're trashing the block 3 and 4 stages to make way for block 5 which they expect to be more robust.

OH SHI

the 4th F1 flight was the first to have a clover on the patch. If it hadn't made it to orbit, SpaceX would not be here today. Thus why its been on every single patch afterwards.

>trashing the block 3 and 4 stages

Well, could you ever sell it rag and bone?
Bring out your junk and we'll give it a home
A broken trumpet or a telephone
Ah, come on, ah, come on, ah, come on
Come on and give it to me

good orbit

second burn complete, GTO attained

>it's not 30° off of the correct inclination
Ariane btfo

lel

WHY

>Ari-ain't

and spacecraft sep. Mission complete.

There's one on the ASDS, too. They like their luck symbol.

I'm still amazed they didn't activate FTS on that one. There might be some nasty consequences yet.

Nifty fact

where will YOU be for the falcon heavy launch?

>eating lunch at uni cafeteria

>reusability is the future
>rocket is to expensive to recover twice
lmao what a fucking joke this whole thing is

they're phasing out the older boosters for block five, which comes on-line this year. No reason to keep outdated stages lying around.

lotta ridiculous liberals on NSF lol

apparently the booster survived

holy shit

hopefully the mounting brackets for the crane adapter are intact. wonder how they'll lift it out of the ocean

Musk is winning too much

Will they go and blow it to pieces now?
Poor thing

>falling for the obvious shoop

Tow it back, rip out the itar stuff, and give it to Luxembourg as a gift. That’s what I would do

shoo shoo bezooz

>I lived, bitch

They failed to fail at landing.

They FAILED to FAIL at LANDING.

HOW DO YOU EVEN.

>You've gotten so good at landing rockets you can't even expend them when you try anymore

...

Final launch of the month, a Soyuz military flight, is going off in 3 minutes!

youtube.com/watch?v=559FQu0WWaw

if the Russians can do one thing right, it's launch Soyuz

Soyuz is one hell of a workhorse, almost a thousand successful launches over half a century!

Anyone know why the soyuz has a roll program just after launch?

Probably to simplify the pitch maneuver.
As you probably know, to reach the desired orbit inclination, the rocket needs to travel to a specific direction.

If you roll the rocket to orient it correctly (it has an internal reference plane, probably), then you only need a simple pitch program to begin the tilt maneuver, instead of both pitch and yaw programs to orient it correctly.

PS: another possible reason is that it could provide some stability

No, it doesn't keep rolling. It rolls a few degrees to a certain orientation then starts pitching over.

Well, then it fits the first explanation I gave.
It makes the tilt maneuver simpler.

Old Soyuz was unable to roll and it had the platform rotate to match the launch azimuth now they do it after liftoff

I was under the impression that having the platform rotate was a design choice to eliminate the need for a roll program, not a solution to the Soyuz' lack of an ability to roll. Interesting that they would have reverted to a fixed structure launch with an added roll maneuver

'no'
