I can't even find it in the catalog, I have it open in a sidetab. Only way to trace it down is ctrl+f
Anyways, 1400 replies now, page 8? I think. People definitely care

>>15360517
epic.
10 hours to go. sheeit. i'll be on my way to work by then

>>15360517
having /sfg/ on the first few pages attracts /sci/ shitposters and lowers thread quality instantly
its far more comfy hidden away down there

>>15360548
just filter it to the top

9 hours

should i call in sick for work tomorrow so i can stay home and watch the launch ?

>>15360774
Yes

>>15360780
scientifically speaking, i feel its the only correct choice in this instance.

>>15360522
Such a stupid image and I'm no fanboy. Define fail? Eventually everything fails but right now and the foreseeable future they're the opposite of failing.

>>15360784
This is an historic event, is justified.
Is the first flight of a cheap, reusable rocket that will open colonization to the moon first and then mars.

>>15360517
Before I get excited, explain to me what the fully tested version of this has to do once it gets to orbit in order to get to the Moon or Mars. I already know the answer, but I just want to see if you and the other SpaceX fans are fully contemplating what this thing is and why NASA or "Old Space" never built one in the past.

That being said, the military could always use a 100 ton launch vehicle, so okay.

nigga don have nothin to eat and whypipo are spending their money on dem space programs.

/sfg/ is /sci/'s best citizen, they make the best, most well informed and most OC filled thread on /sci/ on a daily basis. people who post /sfg/ content outside of /sfg/ are all human garbage with nothing to offer, too ignorant to even get a single (you) if they were to post in /sfg/

When the spinning ball-Earth is finally exposed worldwide for the 432 year deception it was, Earth's entire population will suddenly be faced with the reality that every government, every space agency, university, secret society, religious organization, mainstream and alternative media outlet have ALL been duplicitous in propping up a monstrous manipulation to fleece and control the masses. The resulting mass mental exodus away from the control system is exactly what humanity needs. Once the flat Earth truth gets out, these lying politicians, spokesmen, reporters and teachers suddenly change from being heralded voices of authority to being ridiculed, shunned and denounced as they deserve. Once the flat Earth truth gets out, these governments, universities, media outlets and other entangled organizations which have long been hard at work weaving this multi-generational ball-Earth myth, suddenly and completely lose all credibility. Once the truth of our flat Earth gets out, so does the truth of these few elite families/societies who have kept this most important and fundamental reality from us for these hundreds of years! Essentially, once the flat Earth truth gets out, so does every other important truth by proxy, because this "mother-of-all-conspiracies" holds under its umbrella literally ALL of the other conspiracies, and exposes them.

It will crash.

It'll be cancelled last second and will launch in another 2 weeks.

>>15360737
Ah good idea, let me setup a whitelist
One word is enough

>>15360808
Refuel.
>inb4 "Hah, got ya!"
NASA wanted to do orbital depots to enable cheaper flights, but that would have cucked a certain Senator from Alabama so he literally banned the word from being said anymore. NASA has always known you can do in-orbit refueling, it just hasn't been done because of a lack of need.

>>15360808
Refueling won't be easy and certainly complicates the whole process, but is probably required if we actually want to get real mass to moon or mars. Theoretically if really required starship could have an extra stage or eject some further tiny stage to transport to the moon, like something similar in size to what Nasa would use. Refueling still probably going to be the cheapest way to get actual bases built and operational though

>>15361880
I genuinely do not believe it is going to be hard. Just because it hasn't been done before (not really), doesn't mean that people haven't done the math and run simulations. They wouldn't have entertained this as an idea at all if NASA didn't want to do it almost half a decade ago, and there wasn't evidence supporting its feasibility.

>more shit in space
Oh wow it’s nothing

>>15361910
In ten years from now when there's a functioning BP system and no one can challenge US hegemony ever again, you are going to be going, "Damn how did that happen?"

>>15361889
It will add a certain layer of complexity to things, how difficult it turns out to be is quite hard to tell. I have no idea how they are actually going to do it but I haven't really looked into it very much. The main issue in my imagination is just actually getting the thing connected to the tanker. I used to like their idea of swapping fuel via the engines but I think they ditched that one for a more conventional solution

>>15361924
It seems like they are still doing the dolphin sex maneuver.

Will it?

https://strawpoll.com/polls/BJnX8dlROnv

>>15361848
This is the most likely scenario.

It almost certainly won't launch but if it does it would be nice, double points if the whole thing blows up. Keep me posted.

>>15361956
It'll launch unless there's an automatic hold at T-2 when all of the systems poll for go/no go and an anomaly is detected. This system isn't be reused, and it won't be recovered. All information they will gather is going to come from telemetry onboard, and visually via ground/ocean cameras. If you've looked into the history of this booster, it's kind of insane they are using it at all. Same goes for the ship too, I suppose.

Personally I am betting on a launch, and if it doesn't break up at Max Q due to the jerry rigged fix they put into place after realize the ship would collapse without it, then the ship will break up as it comes back into the atmosphere due to tiles falling off.

>>15361846
It is supposed to

Are they going to pay good money n mars?
Asking as a surveyor or geodetic engineer

>>15362011
Yeah, probably once someone figures out how to start the colony beyond more than just serving as an amusement. In all likelihood, LAVA TOOBS will be the way to go, and of course, locating water will be important.

>>15360522
biggest ipo so far

>>15362029
SpaceX never had an IPO. It's privately held, and like the fourth largest privately held company.

>>15362011
i imagine most of the early colonists are gonna be contract employees that end up bringing their families over

is there any way at all to verify this is real and not just another CGI like the other launch and the moon landing etc?
All we see is just video streams and photos which can be easily faked.

>>15362548
None of us are real bro, it's just you talking to a bunch of bots

So 150 tons is 150.000 1 liter bottles of water? Thanks SpaceX lady. But how many football fields is that?

It's canceled.

CANCELED

>>15360517
>launched scrubbed
no it ain't

>>15361879
>"Hah, got ya!"

Here's the checklist that should be clicking away in your skull right now:
>successfully launch SS (scrubbed for now)
>successfully launch and orbit SS
>successfully launch and orbit SS at full capacity
>successfully test an SS moon lander to Artemis specifications*
>successfully launch and orbit SS moon lander and SS tanker at full capacity, complete successful orbital refueling
OR:
>successfully launch and orbit heretofore unmentioned (SpaceX CGI always shows SS's "mating" in space to refuel) fuel depot
>successfully launch and orbit SS tanker at full capacity, complete successful orbital refueling

Lot of flights, but at least you're at the point where there's some kind of lunar ship being fueled for translunar injection. How many years? Best of luck and kudos, but I don't see this syncing up with Artemis III, even at NASA's snail pace.

*The present SS lander design in picrel is fucking ridiculous, btw. It's a reusable vehicle essentially carrying a giant empty fuel tank that will never need to hold the TLI capacity again so it's tall as shit and everything in the cargo hold has to be winched down around it. Break the fucking thing into two parts and discard the TLI stage at lunar arrival. My eyes get cancer every time I look at that "Destination Moon" cosplay shit.

Yusaku Maezawa ( DearMoon) has given clear and concise information about the valve issue

>"With a test such as this, success is measured by how much we can learn, which will inform and improve the probability of success in the future as SpaceX rapidly advances development of Starship," SpaceX said in a tweet during Monday's launch countdown.
>Cryo liquid for fuel+oxidzer stored at -207 *C
>Muh frozen valves

I'm confused as to how/why they would have frozen valves after so much testing.
Is this an anomaly? Or an oversight?

>>15365296
>>15365457
>Or an oversight?
It depends what happens next. If they keep having issues then it will become more clear how incompetent SpaceX is. If they make it to orbit and have a successful launch + splashdown, then it will have been an anomaly.

>>15360517
Where can I see the countdown/updates?
Google only gives me news about the cancelled Monday launch.

>>15366968
SpaceX is hardly incompetent as a whole. Falcon 9 is still running great.

>>15368429
besides /stg/ as another anon has noted, nasaspaceflight.com is likely to stream it

Is that 11 hours in regular time or Elon time?

I cared last time and they canceled, im going through that again.

>>15362548
literally go and watch it yourself live

T-3 hours 30 minutes

They have literal mexicans with hammers working on Starship.

Weather seems to be shit, possibly scrub because of it.

Felon Husk doesn't care about Black people!

Fellas, please, do we have a continuous video of the thing actually tearing itself off the platform and ascending? The flat earthers will be screeching thanks to the retarded feed that cut off every time the launch itself was viewed

everybody moderating the feed to youtube should be fired and shot in the back of the head. Bunch of hypomasculine twits with voices like a lesbo with a sore throat.
