They are done, Starship will have eaten up all its possible customers by then. Its impossible to undercut Starship LEO costs once fully operational.

>virgin orbit is dead
Thanks to the fine print on one the big loans Branson gave to VO, he gets first dibs on all of its assets in a bankruptcy. He could just buy everything up for pennies on the dollar and restart Virgin Orbit 2.0 while all of the current investors get screwed over.

>astra is dead
Yeah, probably. They run out of runway somewhere around Q3.

>terran is dead, starship isnt getting faa approval
Now you're just making things up for the sake of being depressed.

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.

source?

how likely is the 17th?

>>15346018
who knows, musk said that its trending towards the end of the third week of april a few days ago
so I guess its more likely to be thursday or friday than monday
idk

Its sooo funny that NO ONE , not a single company has been able to replicate what Falcon 9 already achieved 6 years ago. Starship will launch next week. They are unironically 10 years behind

Why is NASA endorsing that whackjob Sagan?
>The following excerpt is from the Sagan biography A Life in the Cosmos, by William Poundstone: One Sunday morning toward the end of summer, Abrahamson, his fiancée, and Sagan were washing the car the couple had been given as an engagement present. Sagan propounded a new theory: that Moses, Jesus, and all the great religious figures of ages past were really extraterrestrial beings. The miracles of the Bible had all happened as described. Moses parted the Red Sea, Jesus turned water into wine, and so forth. They used advanced technology that was perfectly normal on their planet—but which we earthlings could take only as proof of divinity.
>That afternoon, Abrahamson took his fiancée and Sagan out to dinner at what was, for Bloomington in the 1950s, a very posh establishment. It was “the kind of restaurant where people went after church.” In the middle of dinner, without any warning, Sagan slammed his fist on the table, sending the dishes rattling. He looked Abrahamson in the eye and bellowed, “I tell you, Jesus Christ is extraterrestrial!”
>The restaurant fell silent. It took a subjective eternity for conversations to resume with something of their former spontaneity. Abrahamson and his fiancée wanted to crawl under the table

Nothing wrong with this

>>15345889
So are they really not going to attempt a soft landing in the ocean with starship? Seems retarded

>>15346070
I'm not sure anybody expects Starship to survive reentry.

So basically Hard R went from some cool mini starship to… a Falcon 9 clone?

>>15346070
From what i heard , SN24 is so outdated (internal plumbing for landing) that the water landing is not safe to test (or something like that)

/pol/ tourists should go back desu

>>15346073
Yes. Proonters on suicide watch
>>15346070
It's literally bellyflopping they dont want it to survive.

fun fact: beside the military launch center, the only other location on that island is a nude beach, and it's a custom for the launch staff, soldiers and scientist to go enjoy the nude beach naked for each launch.

these were posted I guess but whatever

>>15346089
SN28 is the new updated version . Imagine testing the landing having high chances of RUD'ing + the data you gather is absolutely not worth it (as you your ship is like 1 year outdated)

Press release

Its funny that Terran R is a Falcon 9 but slightly bigger. Also they wont have the rocket ready until at least 2026. What they are gonna do until that moment ? They just launched once and failed

They though "SpaceX tried Falcon 1 and went directly to Falcon 9, so we will do the same " . But SpX at least achieved orbit and won a big NASA contract to develop Falcon 9

>>15346105
isnt this much better than falcon 9?
in 2026 falcon 9 will be obsoleted by Starship, but still

https://twitter.com/thesheetztweetz/status/1646151373765976072

>>15346118

https://www.cnbc.com/2023/04/12/relativity-all-in-on-terran-r-rocket-shifting-3d-printing-approach.html

> The company is currently talking to NASA about an upcoming mission that it no longer expects to fly on Terran 1. It’s already moved other customers over to Terran R.

>Although Relativity expects it will be another three years until Terran R debuts, with a target goal of 2026, the company has so far won launch deals from seven customers worth over $1.6 billion for future flights on the rocket.

>“We have won 100% of the commercial contracts we’ve gone after to date against other competitors,” Ellis emphasized.

> Since Ellis unveiled plans for Terran R two years ago, the rocket’s design has continued to evolve. But Relativity’s update on Wednesday features its most dramatic change yet, with the 3D-printing specialist incorporating an aluminum alloy into the rocket’s initial models through manufacturing “tank straight-section barrels” – a practice that is more traditionally common in aerospace.

>Relativity made a name for itself with its 3D-printing approach to manufacturing rockets, building massive additive manufacturing machines. The company 3D-printed about 85% of the mass of its Terran 1 rocket, and previously planned to get that number above 90%. Ellis declined to specify what percent of Terran R will now be 3D-printed in the company’s new “hybrid manufacturing approach,” emphasizing instead that the shift is to prioritize its timeline to first launch.

> Relativity plans to add on to its existing facility in Cape Canaveral in preparation for Terran R launches. The rockets will be built at its 1-million-square-foot factory in Long Beach, called “The Wormhole.” Ellis estimated Relativity will be capable of producing upwards of 45 rockets a year from that facility.

>>15346118
> Here is the latest design and target capabilities for the company’s reusable Terran R rocket, aiming for a 2026 debut:

2026 if we don't count in future delays that is

>>15346130
>Relativity plans to expand LC-16 in Florida to accommodate Terran R, with a larger launchpad next to the Terran 1 pad:

How long it took for SpaceX to develop F9 ?

>>15346111
well they have 1.6 billion of future flights for the rocket already and I guess enough funding and runway to do so
Falcon 1s 4th flight succeeding meant that SpaceX got the funding they needed, Relativity doesn't really seem to need the funding, so it might actually make more sense to pivot to Terran R immediately
and I mean, what if they had a working system with Terran 1? How much revenue and customers would that even have? minisat launches seem almost completely pointless at this point with rideshare, they would also use a lot of the companys time and effort to do those launches, probably engineering resources etc

Why are printers hated on /sfg/? Seems a useful manufacture methos idgi

>>15346138
You're probably right

>>15346136
That’s a hard question because Merlin dev began in 2002, so you could argue it took 8 years. Also, Falcon 9 test tanks were being built in 2007ish - before Falcon 1 reached orbit, even.

imagine getting in this shit to fly to mars

>>15346152
forgot pic

>>15346157
this just reminded me of the fact that Teslas are unreliable

>>15346136
Falcon 1 first success and 4th flight was in 2008, fifth flight 2009
https://en.wikipedia.org/wiki/Falcon_1

The announcement of falcon 9 was in 2005, the first test flight was supposed to be 2007 but slipped into 2010 and the first commercial launch was in 2012

https://en.wikipedia.org/wiki/Falcon_9
> SpaceX originally intended to follow its Falcon 1 launch vehicle with an intermediate capacity vehicle, Falcon 5.[42] In 2005, SpaceX announced that it was instead proceeding with Falcon 9, a "fully reusable heavy-lift launch vehicle", and had already secured a government customer.

pic from
https://en.wikipedia.org/wiki/List_of_Falcon_9_and_Falcon_Heavy_launches_(2010%E2%80%932019)

So not really sure, maybe you could say 5 years from announcement to first test flight, 7 years from announcement to first commercial flight, but it was developed alongside falcon 1, which had its first failed test flight in 2006
is 2026 possible for Terran R? does the abandonment of Terran 1 completely speed up development of Terran 1?

>>15346152
Imagine landing on the moon on this

>>15346142
nothing wrong with printing some parts that are difficult to manufacture otherwise, printing something that is easy to do with cheaper and more traditional manufacturing methods is kind of retarded though

>>15346160
you have options other than tesla. you dont have options besides starship.

>>15346079
And you should leave with them, as well. Either talk about spaceflight, or shut the fuck up, you insufferable child.

>>15346160
your mom is unreliable

Speaking of upcoming medium lift launchers: How’s Neutron doing?

>>15346163
Needs moar knobs.

>>15346189
Neutron will not be doomed from the start only if its very cheap to produce and the full reusability really works .Otherwise its over

>>15346189
Still early days. Archimedes is in some stage of component testing and they're working on the first pathfinder tanks. That's about where you'd expect them to be at this point in their timeline.

>>15346167

open the pod bay doors, HAL.

>>15346269
HAL was just doing what was needed to finish the mission
HAL did nothing wrong

Can anyone name ALL of the Falcon 9 ripoffs in development?

JUICE launch tomorrow

>>15346270
Why didn't he put Discovery on a slow roll about its long axis? Bowman would be fucked, the ship has to be stationary for his maneuver to work. HAL was dumb.

>>15346280
There are quite a few, but suffice to say, they're all chasing ~17 year old design.

F9 was designed ~2007, and most of the clones that do get finished will hit the ~20 years mark

>>15346269
No

>>15346280
China has like 100 private companies with retarded names, and the companies have sometimes multiple names, but also names that companies in other countries have
for example, ispace

https://en.wikipedia.org/wiki/Ispace_(Japanese_company)
https://en.wikipedia.org/wiki/I-Space_(Chinese_company)

> i-Space[1] (Chinese: 星际荣耀; pinyin: xīngjì róngyào; lit. 'Interstellar Glory')—also known as Space Honor,[2] Beijing Interstellar Glory Space Technology Ltd.,[3] Interstellar Glory[4] or StarCraft Glory[5]—

not really sure why they have so many different names for the same entity

anyway, galactic energy is apparently developing Pallas 1 and 2 which are going to be falcon 9 competitors
> The Pallas-1 is a medium-lift orbital launch vehicle under development by the company.[11] The first stage will have legs and grid fins to allow recovery by vertical landing (much like the SpaceX Falcon 9).[11] The first launch is scheduled to take place in 2024.[12]

> Pallas-1 is planned to be capable of placing a 5-tonne payload into low Earth orbit (LEO), or a 3-tonne payload into a 700-kilometer sun-synchronous orbit (SSO).[11][13][14] An upgraded variant of the rocket, Pallas-2 (Chinese: 智神星二号), is currently under development. Using three Pallas-1 booster cores as its first stage, Pallas-2 will be capable of putting a 14-tonne payload into low Earth orbit.[15]

https://en.wikipedia.org/wiki/Galactic_Energy

LandSpace is developing a falcon 9 clone Zhuque-2, 4 tonnes to LEO
it was the worlds first orbital attempt with a methane fueled rocket

https://en.wikipedia.org/wiki/LandSpace

ispace mentioned before is developing Hyperbola-2, which will be a methalox fueled, booster reused 1.9t to LEO

Then there is rocketlabs Neutron, Relativity with Terran R, Ariane with Ariane Next, Blue Origins new glenn that is a heavy-lift rocket so idk if that would be a competitor to falcon 9, but it was supposed to be partially reusable at first

>>15345961

>>15346321
There's only so many hairs on the body you can relocate no matter how much money you have.

>>15346306
They should have just gone for a Rocket 3.5 design; keep the first stage as-is and ditch the pressure fed-second stage for something based around a vacuum optimized delphin engine. They would have ended up with something that looked a lot like a stainless steel version of Electron that ship it's GSE around in a cargo container, which isn't a bad place for a launch vehicle to be.

Erig Berger News : SpaceX continues to work toward a Starship launch attempt on April 17, pending an FAA license. (Could come as early as Thursday or Friday). Assuming it does, lots of other factors in play. But launch site weather looks good Monday—70s, sunny, modest winds gusting to 20 mph.

>>15346776
Most of those people aren't going to make it. Relativity probably won't make it either since they're going to be zero revenue for at least 3 years. You can't follow the SpaceX roadmap a decade late after SpaceX already built their moat.

>>15346843
There will always be certain costs to satellites that cheap upmass won't negate. Anything electronic for example, you still need pretty expensive rad hardened gear for it, same goes for comms gear. Maneuvering systems are also expensive although ther has been some great work dropping the price on them, it won't be truly cheap for quite some time. the real benefit will be is power for satellites, suddenly you can slap dozens of kw of solar panels on your shit easy. I think if I had some megabucks I would be looking at making a space based spiral welder that you can feed with aluminum or stainless steel rolls you send up on starship, to me this seems to be the most logical way of making affordable pressurized space of whatever size and that can be potentially spun up for gravity. After all this has been solved on earth for a long time, what's the best pressure vessel mass produced right now? The soda can. Using robits and shit with flat panels seems waaaaay too needlessly complex.

Because in the span of like 2 years SX proved you could make insane pressure vessels with nothing but off-the-shelf sheets of metal. The whole point of printing was to be fast and cheap and they got dunked on before even attempting to fly Terran 1

>>15346869

Lead.

>>15346869
how much of that overall price is actual value, and how much is "aerospace grade" embezzlement
for the equipment, how much of it is min-maxed effectiveness/mass to save every last gram
spacex itself was compelled regularly to use the "traditional" 100x cost equipment because it had some bugman's stamp of approval on it, and chose not to because the equipment was no better than doubling down on a technically lesser alternative

>>15346884
Why? Because they have sauce and imagination?

The least surprising design pivot. At least they didn't fall for the isomeme

>>15346857
The CZ-6A is a mod of the CZ-6 that adds back in the second first stage engine from its CZ-5 booster heritage. The CZ-8 is just a CZ-7 with one pair of liquid boosters removed. The 6A only started flying last year and the 8 only started flying three years ago. Bringing both from design to launch took a minimal amount of work and was fairly low risk given the flight records of their parents. It's not clear yet if there's a need in the Chinese market for either variant, but right now China is trying every proposed design at the lighter end of medium lift and letting natural selection sort out which ones are the most viable.

>>15346927
They had $1.3B total raised at the end of 2021 and maybe $600M cash on hand at the end of 2022. There's no way they'll make it to 2026 with zero revenue and ~1000 employees. Layoffs are coming.

>>15346106
>NET 2026 for a worse new glenn

Yes. As grim as it is, Hard R is still the only [other] rocket under development that survives in the post-Starship world. Investors want a chunk of that world and the SpaceX price tag is too high ($137B at latest valuation)

>>15346942
Layoffs will make it much harder to actually get Terran R flying by 2026. They have billions of dollars worth of launches already lined up and might be able to grift out another round of investment, and pretty good standing with the government which can hand them some generous contracts. Terran 1 was never going to be a huge money maker for them, and Terran R is a vision which offers a realistic chance of being semi-competitive with SpaceX. The only reason to continue trying to launch 1 would be to test hardware and reassure investors.

I do think that this is a risk, but a calculated one and perhaps the best chance Relativity has of surviving the coming nuspace filter.

I would actually prefer if they made their own way to the moon. It would be nice to have a meet-up on the surface, and to not have one country be the sole controller of access to the moon.

That said, China is a cancer and I don't really want them to succeed.

I would be happy to see Russia stop being shit and provide some real competition to the US, but that isn't the most realistic.

Ariane will survive for government contracts, same with ULA. I see no future for any others except perhaps stoke and rocketlab but even then I have my doubts about them surviving even if starship is 5-10x the promised prices. Will depend a lot on if starship can fill their payload bays reliably and if they decide to build a cheap kick stage you can stick on any sat so even the ones with weird orbits can rideshare.

HM-7B (french-led) was more than fine for the whole Ariane 1-4 period
Then Ariane 5 was first supposed to be the Hermes launcher so early development of the ECA variant, let alone a larger variant was delayed to well into the 90s
Vinci engine (Reignitable Expander cycle) finally starts development in 1998 or so, early dev years are spent constantly changing the specs, finally a very large, and harder to make , expander cycle was chosen
Then Early Ariane 5 shat the bed, Ariane 5 ECA had delays and had a big failure on maiden launch, dot com crash so space market prediction collapsed, and Arianespace and CNES had internal problem, this put Ariane 5 12t/ME with Vinci at a low priority and in development hell for the 2000s, also dual launches turn out to be harder
Early 2010s and Ariane 5 ME And Vinci engine get more support, the german (Astrium-EADS) build some factory for it in Munich, and lobby for it, that’s why all Ariane 6 proposals had a Vinci too. Also Vinci R&D move more from France toward Germany
2014 Arianespace, somewhat surprisingly, gets bought out by Airbus safran and Ariane 5 ME gets cancelled, this completely changes the timeline for the development of a Vinci upper stage

Upper stage development has been rocky since, it was one of the main reason for the delay of Ariane 6 over the past 2 years. Also there were a lot of bickering Between France and Germany over where the Vinci would be tested

>>15347174

It turns out that this was mostly an ego project by one German angel investor, and they pulled out a few months ago. There really hasn't been any news since but it's not looking good. I'd put them at something like tier 3.5.

>Skyrora, Isar
One of these has a good chance to carve out a space in the European captive market, especially with the state Vega is in lately. I'd say that Isar has a better chance than Skyrora since Spectrum has three times the payload of the Skyrora XL and it's launching from Kourou instead of SaxaVord. British bureaucracy getting in the way of quick launches was one of the big contributors to Virgin Orbit falling apart.

>>15347174
>It was, therefore, decided at the end of 2005 to transfer the management and existing assets of the former Vinci development to the FLPP in order to form the basis of a Demonstrator (esa bulletin 2008)

There; Vinci was downscaled from an actual program to just a demonstrator for the FLPP (early Ariane 6 studies, a lot of them were ditched and became useless) and stayed that way until around 2013 lol. And the program restart was by quite different, more German teams.

Also if you want to go a lot earlier for why Europe never developped an alternative to HM7B, basically it goes back to the Europa days, after Britain left the program they had to completely redesign Europa, France Germany and Belgium agreed on Europa III with a Hydrolox upper stage; but there was a disagreement, The french side (Engine company was SEP/SEPR based in Villaroche) wanted an open cycle hydrolox engine based on their earlier studies, the German side (MBB, based in Ottobrunn) a closed cycle based on their collaboration with Rocketdyne (fun fact this collaboration was the basis for the SSME); the German side won for Europa III, but the whole Europa program collapsed, then the project was reborn, with streamlined management, under LIIIS/Ariane, now with French supermajority of funding, the Ariane 1 would have the open cycle, easier to develop HM7B. From there the CNES kept control of the launcher design and made sure to keep this engine for the upper stage. 70s economic crisis + Ariane itself being expensive to make and honestly a miracle it even worked made sure that there wasn’t much room for a second upper stage engine development in Germany .
Which is a shame because HM7B was by far the least reliable part of Ariane 1-4

>It turns out that this was mostly an ego project by one German angel investor, and they pulled out a few months ago.

He just listed them alphabetically you nonce

Do you guys think a Sea Dragon size launch vehicle could be made on Mars to send massive payloads to the outer solar system? If not Phobos or Deimos to take advantage of the lower gravity (and to give Mars it’s rings sooner).
To be clear, Sea Dragon is a retarded idea for where and when it was conceived but a better terrestrial rocket with that ~25m diameter would be so cool in a better setting for it.

>>15347246
Ariane 6 uses Vinci which is reignitable (like 5 times, more is possible), but the structure is quite heavy and inneficient, they got rid of the common bulkhead that Ariane 5 ME was supposed to have. The manufacturing methods are also kinda steamlined but this comes at the cost of heavier structure.

Ariane 62 suffered quite a bit from the mass creep of the upper stage and probably will need the 2025 P160 booster upgrade to reach its target payload

Also another problem is that ULPM (Ariane 6 upper stage) needs an addition called Astris to launch satellite constellations, this is why Kuiper constellation launches on Ariane 6 are NET late 2025

>>15347280
Well, Starship will be operational before NASA can gather the funds post Artemis. Maybe the scientists at rich unis like Harvard can make their own probes and have SpaceX handle deployment and such at a super low cost? It could keep it in the budget for them.

>>15347285
the costs involved with making substantial probes are still really high, cheaper launches aren't going to suddenly let harvard throw their own voyagers
maybe if a bunch of them worked together they could do it.

>>15346869
sure there are some costs that can't go away, but not everything needs to be machined aluminum and $100 mcmaster-car bolts. I suspect much wont change over night, but eventually someones going to get the idea of building a $2,000 satellite and just sending another up if it breaks.

>Krystal zero-g indicator when?

Looks like starship is not long for this world

why are there so many insufferable faggots at NSF? Can't listen to most of their videos

>>15347520
me again, here let me help you out since we all know what your response is going to be

GO BACK AND ROPE NOW TRANNY R*DDIT LOL

just grow up and shut your stupid mouth kid

>>15347445
the starship AI will be named Krystal

There are many factors that can affect the volume, velocity, and force of ejaculation, such as age, health, diet, sexual activity, and genetics.

Ejaculate will leave the penis at roughly the same rate of travel as a city bus, about 28 miles per hour (12.5 m/s). But it can reach speeds of 43 miles per hour (19.2 m/s) depending on how long since the last time he came. The average volume of ejaculate is up to one teaspoon (5 ml), and the average weight of ejaculate is about 6 grams. Assuming a person massing 75 kg "dry", we can use the Tsiolkovsky rocket equation again to get a delta-v figure of:

dV = Isp * g0 * ln (m0 / mf)

where Isp is the specific impulse in seconds, g0 is the gravitational acceleration constant (9.8 m/s^2), m0 is the initial mass (75.006 kg), and mf is the final mass (75 kg). Substituting the values for ejaculate velocity and mass, we get:

dV = 12.5 * 9.8 * ln (75.006 / 75) = 0.016 m/s

or

dV = 19.2 * 9.8 * ln (75.006 / 75) = 0.025 m/s

So, the ISP of ejaculation in relation to rocketry would be even lower and more inefficient than a fart. However, this is a very rough and unrealistic estimate that does not account for many factors that influence ejaculation, such as air resistance, gravity, angle, pressure, and temperature. Therefore, I do not recommend using this calculation for any serious purpose.

>The obvious, but politically difficult, solution is to roll the NRO into Space Force. It is simply intolerable for the Intelligence apparat to put its own priorities and bureaucratic processes above the needs of combatant commands.
ban the nro

doesn't the NOAA actually violate the 1st amendment when they stop earth sat images?
freedom of the press and all that

Are any of these smallest launchers publicly traded? Or is it VC shit only? Man I want to short these fucks onto the dirt.

When will FAA give SpaceX license to fly?

>>15347675
Kek pure disinfo article, as if the US doesn't have a shitload of military imaging satellites.

>>15347742
In approximately two weeks time

>>15347675
I think the problem is that the NRO is primarily an intelligence gathering force, while the Space Force isn't. It's like trying to roll the CIA into SOCOM. They actually had to rely on the CIA early on and just said, "Fuck this." and created parallel organizations or expanded the powers of of preexisting ones where applicable. I expect that the same thing will happen here. The Space Force will get tired of butting heads with the NRO, and just go "I'll just make my own NRO, with blackjack and hookers!"

>>15347748
It's a point who controls what sats. The NRO probably has the most, and the most advanced ones at that. It would make sense that the Space Force would want to just roll the NRO into its command structure as this would expand its capabilities and make other branches more reliant on them while simultaneously justifying their existence and why they need more money. Simultaneously I can understand why the NRO wants none of that.

>>15347741
well astra is, but its about to be delisted so you are way too late

anyway, the pic is from bing chat, I copypasted this >>15347122
and asked if these companies have publically traded stock on the stockmarket but STOK is not Stoke aerospace, its the stock for a completely unrelated (probably, too lazy to check) biotech company called Stoke Therapeutics

not really sure what Vector refers to here
VACQ or Vector Acquisition Corporation was a vehicle to SPAC rocketlab, an investment company nothing to do with aerospace by itself
https://www.businesswire.com/news/home/20210825005365/en/Rocket-Lab-Completes-Merger-with-Vector-Acquisition-Corporation-to-Become-Publicly-Traded-End-to-End-Space-Company

so ASTR, but shorting a company that is already dead and the stock is dead seems kind bad from a risk-benefit perspective
you could short rocketlab I guess, but I doubt they will go bankrupt, they are probably going to be number 2 after SpaceX (or Relativity, but that is not public)

Does the US have real time image like real time internet? I'm not talking about sat image taken 1 hour ago or 6 hours ago or daily image, but REAL TIME, <1 second, like the internet. AFAIK, there isnt.
