We Mars nao

nighttime launches are always nice

>>9882602
Very kino.

meanwhile, the iridium static fire just happened: https://twitter.com/SpaceX/status/1020520790108672000

I suppose this thread can do double-duty, since there is only a 3-day gap between the two launches? depends how many posts there are. Regular F9 launch threads haven't been too busy here. But, we're back into block 5 / landing land so maybe not

>>9882653
We can always fill it with shitposting and BTFO-memes?

>>9882700
This, space shitposting is fun.

>tfw landing EVERY TIME from now on

>>9882722
Yep. what would be future F9-expendable payloads will probably be bumped to FH.

It's after 1:50 EDT. Are they going to keep us up all night?

>>9882759
just wait, it'll launch at the end of the 4-hour window ;^)
I hope you have some snacks in order

>>9882759
>It's after 1:50 EDT. Are they going to keep us up all night?

It's not launching for another ~24 hours, Anon.

Damn it.

>>9882802
>>9882807
Im always impressed by the size of these things.

>>9882841
makes the fairing recovery that much more impressive. Here's an iridium encapsulation pic that shows the scale pretty well

My first rocket!

>>9882853
How many left over screws did you end up with?

>>9882856
funnily enough, on one of the early recovered core teardowns they discovered some parts that "didn't exist" on the BOM for that specific stage. Someone probably got in trouble for that, heh.

>>9882853
what's the news on that pedestrian walkway and zoning issue with the housing next to SpaceX's sprawl buildings? Last I looked it was buried in some nasty politics

>>9882863
*SpaceX's sprawl of buildings

>>9882863
You asked about the walkway thing last time I posted. I totally remember that

What will the next Falcon Heavy in November consist of? Is it all Block 5s as well? That should be quite the performance bump. Hope the next one doesn't come apart because of this.

>>9882870
small microcosms of infrastructure related politics fascinate me. I wrote a paper on my town of 5000's whole yearlong drama surrounding whether we would remove our streetlights or not

>>9882874
that one should be fun; it's a shitton of smol AF payloads and university cubesat stuff. Will also demonstrate long-coast & specific-orbit capabilities so the AF can cert it for defense payloads or something like that.

>>9882802
They sure like their spikes.

>>9882879
FH is already certified

>>9882896
is that why they won that recent AF contract without having to do the demo mission beforehand? I thought STP-2 was necessary for full certs

>>9883378
dooooood >>9882787

we think alike

Telstar 19 will be the heaviest commercial satellite ever launched. 7,075 kg

>>9883626

>>9882875
If you want a real fun one, look up how they put the F9 first stage up. The FAA had a huge problem with that.

>>9883626
>heaviest commercial satellite
>to GTO
>with attempted landing
Sheeeeeit, I bet this is physics-defying according to ULA's top mechanical engineers.

>>9883672
it's really not that bad - MECO is at 2:30, which is pretty early. Stage 2 does a lot of the heavy lifting. Will still be an energetic landing for sure

>>9883672
hol up
>they're doing it with the F9
>not the heavy
oh boy this will be interesting

>>9883679
How does this one compares with Koreasat 5A (7700 lb) launch to GTO? Because F9's landing was quite toasty back then.

>>9883690
>Koreasat 5A
MECO was 3 seconds later for that than for this upcoming launch. The block 5's upgrades having to do with the thermals is probably the biggest improvement for this sort of thing. Can bleed off more energy with the atmosphere without worrying about stuff overheating etc

>>9883694
Fuck, I just checked - Koreasat 5A's MECO was at 2:40 so almost the same but this time the payload is TWICE that much, holy fuck. I hope baby can handle it.

in the meantime, enjoy this paper by Jon McDowell on why 80km should be the definition of space rather than 100km: https://www.sciencedirect.com/science/article/pii/S0094576518308221?via%3Dihub

Bric Eerger has written a piece about the Starliner incident https://arstechnica.com/science/2018/07/boeing-may-have-suffered-a-setback-with-starliners-pad-abort-test/

my (Doubt) levels are decreasing, but I'd still wait on official news of what happened

>>9883859
"Ars has heard several different accounts of the accident, but absent concrete information from Boeing it seems improper to speculate whether there was damage only to ground equipment in support of the test or to the Starliner test article itself. Boeing officials have apparently told NASA they believe there is an operational fix to the problem rather than a need to significantly rework the Starliner spacecraft itself." key part of the article

we'll just have to wait and see

BFR WHEN

>>9883870
Right now they are still working on the machines then need to build the actuall thing.
And the building that they want to put those machines in cant even be build yet because thay are bringing down other buildings on the site first.
First "first stage" BFR test somewhere late 2022
Unlike anons here who claime 2020

>>9883927
Shotwell says 2020 for suborbital hop tests.

>>9883859
>>9883862
article has been updated with Boeing's response:
"The company said it conducted a hot-fire test of the launch-abort engines on an integrated service module at the White Sands Test Facility in New Mexico in June. The engines successfully ignited and ran for the full duration, but during engine shutdown an anomaly occurred that resulted in a propellant leak. "We have been conducting a thorough investigation with assistance from our NASA and industry partners," the statement said. "We are confident we found the cause and are moving forward with corrective action. Flight safety and risk mitigation are why we conduct such rigorous testing, and anomalies are a natural part of any test program.""

>>9882700
You know it!

Telstar 19 cost $250,000,000 according to the Telesat CEO. One of the more expensive Falcon 9 payloads?

>>9884127
...that means it's only slightly more expensive to build the entire thing out of solid gold, by weight. Jeez

>>9884130
glory to high technology
where materials are the cheap part, no matter what material you choose to use

So if BFR performs as stated and kickstarts the space age by dropping launch costs, will we begin to see legit Musk cults forming?

>>9884234

>>9884127
Zuma apparently cost $2B+ and burned in the atmosphere because of shitty separators from the contractor

>>9884248
>shitty separators from the contractor
Inadequate integration testing, including an apparent lack of shake testing to see if they could handle the stresses of launch. The contractor was Northrop Grumman.

>>9884234
>Implying Musk cults don't already exist

>>9884256
Yeah but they are pretty casual, I'm meaning more serious and organised cults. I guess if the madman does pull it off then he probably deserves it.

>>9884255
>>9884248
I hope I'm around in 2092 when the Zuma files are declassified. Although it's probably some boring spy sat

>>9884260
Idk about Musk cults, but I can definitely see a Bezos blood cult forming after he turns us into an interstellar species by the sheer power of money

>>9884273
well yeah.

There is a reason the future leaders of Mars will be called the "Elon".

>>9884310
That does seem like a staggering coincidence

>>9884310

If you're a rocket nerd can you tell me who Jack Parsons was?

>>9884341
why should anyone bother replying to someone who posts bottom-of-the-barrel /x/ images?

>>9884330
block 5 is a cute

>>9884350
>why should anyone bother replying to someone who posts bottom-of-the-barrel /x/ images?
I wish to be educated - who was Jack Parsons?

>>9884272
I like the paint job on the fairing. Too bad Mr. Steven is on the west coast.

>>9884390
unless they improve the fairing accuracy we're going to need four separate Mr Stevens. Or, I suppose they could just delay the landing of one half, and take down the recovered other half to make room for the half still floating down on the net.

>>9884398
Why don't they just have the fairings hinged together? That way it can open for payload release and then close and come down as one piece.

>>9884404
the current fairings work like so:
>The two halves of the fairing are fastened by mechanical latches along the fairing vertical seam. To deploy the fairing, a high-pressure helium circuit releases the latches, and four pneumatic pushers facilitate positive-force deployment of the two halves. The use of all-pneumatic separation systems provides a benign shock environment, allows acceptance and preflight testing of the actual separation system hardware, and minimizes debris created during the separation event.

it would be tough to justify a whole new design when the present systems works pretty well.

5 bongs to go

It's not going to launch until right at the end of the window is it?

>>9884633
I hope not.

Time to go to safeway for some launch food. What should I get?

>>9884703
Hot Dogs. They are rocket shaped.

GOOD LUCK FALCON CHAN!

>>9884814
Are there other rocket girls like this?

>mfw I just found out that Elon Musks brother is working on high-density efficient indoor hydroponics

We gon make it lads, everything is almost ready for Mars.

>>9884818
Sorry bro, only one I know of. We need some drawfags on it.

>>9884814
>>9884818
I'd love to see a Soyuz-Chan, or a morbidly obese SLS-Chan.

>>9884844
Pity.

D-IV H would be thicc though. We've already got the shuttle sisters (the survivors at least if anyone can find that one image). The New Zealander's tiny rocket and Japan's souped up sounding rocket would both be lolis.

>>9884847

>>9884837
yeah he's a pretty big health foodie too

Speaking of the Shuttle Sisters image (There's 3 of them, all are bawling their eyes out, pretty sure it was post Columbia burning up), anyone have it? I'm trying to find the fucker but I dunno where it is.

after bangabandhu-1, all of the customer-supplied promo videos have been lame in comparison. I want more 20 minute 4:3, 480p propaganda with shitty production value

>>9884856
I would figure that'd be more along the lines of what Soyuz would look like, what with it having 1700+ launches under its belt.

Or would Soyuz be a Russian hooker?

>>9884924
>Or would Soyuz be a Russian hooker?

yes

Conestoga would be a batshit insane aunt I suppose?

>>9884924
the joke was "Saturn V is a big strong German lady"
Soyuz is a Babushka who's been around the block so many times that it counts as a marathon

>>9884930
>All solids
>Third image on the wikipedia page is of it exploding and 4 of its boosters spinning wildly off into the sky
Sounds about right. Minotaur would be it's much saner sister. Minuteman and Peacekeeper would be the father and mother (or whatever suitable generation group), respectively.

>>9884933
>the joke was "Saturn V is a big strong German lady"
Yep, only just got the joke now that I remembered S-V was built with a shitton of German help.

Actually, revision to Delta 4 Heavy: She'd be an Oujou, with Delta II and Atlas V being the typical hanger-on girls. Delta II would have 9 boosters and be a mite bit twitchy (due to the rather spectacular launch failure when a booster casing ruptured 13s into the flight).
All 3 quite fiercely dislike F9.

Every successful launch from now on is another nail in ULA's/Boeing's coffin until they can somehow match cost effectiveness.

Drone ship not pad I think, but yes they are recovering.

>>9884999
No

>>9885001
Can't have ULA lose to a "start up"

>>9885002
I didn't mean see its return TO the mainland, I was wondering if we can see it FROM the mainland. It being nice and dark and all.

>>9884999
nighttime launch; might have some good 1st stage footage (from 1st stage cameras) if the ASDS has lights on. We've had uninterrupted 1st stage views before
