How long before the first space station powered by a nuclear reactor exists? Solar panels are like having horses on a treadmill for power.

Absolute retard.

Falcon 9 Block 5 has flown 111 times, with a success rate of 100%. It has landed 101/104 times, giving its landings a success rate of 97.1%.
Applying this to Starship, would you trust your life flying to orbit on this? How about performing a propulsive landing? I think I would desu.
Also a reminder that in two of the three failed landings, the Falcon 9 landed intact but just missed its target. So one could argue it’s landing success rate is 103/104, or 99%.

>>14704665
>Applying this to Starship, would you trust your life flying to orbit on this
Isaacman et al. have already committed to flying in a Starship on ascent *AND* belly flop landing
if it's good enough for them it's good enough for me

>>14704656
Solar power has higher output and efficiancy in orbit retard. There's no point in having nuclear reactors on a space station.

Add Lunokhod 201 to the list of notable launches in /sfg/ lore

Relativity is proof a total fucking twink can be a space CEO
there's still hope for me yet

>>14704665
I would say yes because F9 was an expendable rocket that was autism rigged to land whereas SS is designed from the ground up to do it

The N11 was a real life rocket designed by Sergei Korolev.
In 1962, Korolev, Chelomei, and Yangel proposed their rocket plans the USSR’s leadership for funding. One would build an ICBM, one would build medium/heavy lift rocket, and one would build the lunar vehicle.
Chelomei won the medium/heavy lift award with his Proton. Yangel won the ICBM award with his R-36. Of course, Korolev would be selected to build the lunar vehicle; the N1.
Now everyone was pretty pissed because they all had their own plans for each category. Chelomei planned the UR-700 for the lunar rocket, and Korolev wanted to use the N11, a two stage N1 without the Block A (first stage).
In a world where the Proton wasn’t selected, Korolev would’ve probably had his N11 flying the exact same jobs as the Proton. The N11 could do 20 tons to LEO, and used 8 of the N1’s NK-15 first stage engines.
Pic related, a N11 launches a Zond spacecraft around the moon. In real life, the Proton flew the modified Baseduzes, called Zond, around the moon a handful of times, but reliability issues led to this never being manned

>>14704666
The Chinese plan is a caveman-simple double launch sample return that does away with the scientific pretense and focuses entirely on the goal of returning a soil sample from Mars

The lander doesn't even make orbit, it's an almost completely untargeted landing in the traditional sense

>>14704690
The Chinese mission is better because it’s not retardedly complex

>>14704672
You'd think that after 60 years of space exploration we'd have developed some better way of cooling down things, I can't imagine how they'd run a reactor in LEO that wouldn't be immediately outclassed by its weight in solar panels

FTL WILL NEVER BE POSSIBLE, FUCK!

>>14704716
Why do so many talk about FTL when .1% light speed would be astonishingly miraculous

>>14704665
Falcon 9 landings have more success rates than many of the other rocket launches.

What a world we live in

S24 is supposedly going to be undergoing testing today. what will they test?

>>14704716
Technically true. Alcuberie warp drive bends space so that the ship never goes anywhere locally.

>>14704672
>There's no point in having nuclear reactors on a space station.
civilian ones, yes. military ones? that's a different story

>>14704764
I was joking about the X-37C in /sfg/ the other day and then Sierra Nevada hired a bunch of "national security advisers"...

>>14704708
>>14704690
There are a lot of good commercially available drone technology.

Can't one be made quite big; have a hollowed out hull, with decendable claw;

Make 100 or more of these (such a mission should be a numbers game, more the merrier, drones are relatively cheap) with some variation in claw design to prevent error or increase odds of success; some have drills, scoops, stirs,

Fill the ship with 100 or 200 of these; they go to different locations, different interesting surface areas;

Some have a vacuum suction,

Get liquidy samples, get rocks, get under surface stuff.

They fly back to mother ship. Each one having a sensor so it's known when all are on board. Each one having an hd go pro.

And then we're golden

>>14704750
Because every point of interest outside the solar system is even more astonishingly far away.

It would take 4400 years to reach the nearest star at 0.1% c.

>>14704764
Would radiation from the reactor be a problem?

Is it water reactor? How's it dispose of materials safely?

All that matters is what is possible, and right now I don't know if even .1% of c is possible. Crawl before we sprint. Sure dream and plan of sprinting, but theres many things I can think of that are not possible

>>14704784
>>14704778
.1% of c is 670,000 mph

>>14704764
A nuclear reactor should be made available to civilian stations in locations where sunlight will not be available for extended periods of time (if at all)

-Anywhere on the Moon that isn't the Peak of Eternal Light

-Mars due to dust storms (at least for early colonies)

-Outer solar system

>>14704808
And the nearest star is 26 trillion miles away. What's your point?

>>14704773
A challenging part might be; well maybe the drones would not be able to stay airborne while their claws or diggers or drills touch the ground, that would throw them off and crash?

So maybe their propellers would be turned off and they'd have to land? That's seems fine.

Also a portion of these can look for or get the samples from the rover.

Other maybe challenging aspect, is sending each one off the ship carefully one at a time, not having them crash into each other, blades cut anything on the ship, and then when returning into it, one at a time, perfectly into the hull and landing in an area without propellers cutting anything or hitting the ship and crashing.

>>14704830
All that matters is what is possible, and right now I don't know if even .1% of c is possible. Crawl before we sprint. Sure dream and plan of sprinting, but theres many things I can think of that are not possible

now they want to use drones to retrieve the samples

ass eating shuttles

>>14704713
The Stefan-Boltzmann Law is a bitch, running a reactor at a very high operating temperature comes with its own set of problems. Still, most of the mass disadvantage is in the rest of the reactor itself and the shielding, the radiators just make it hard to scale without deploying what could have been a large solar array and they're extremely fragile so nuclear is not as big of a boon to warfighting as people think, especially once considering the extra mass which limits acceleration.

>>14704690
How does it grab the samples and return? Explain to me like I'm a particularly idiotic moron (hint: I am).

China sends a ship to mars, it lands on surface, blasts off back to earth?

Or china sends a ship, gets in orbit of Mars, sends thruster sported lander/s to surface, collect samples, thrust up to orbiter, enter it, blast off back to earth?

>>14704716

>>14704874
>>14704713
The near by sun is a bit bigger of a nuclear reactor than any you will make any time soon

nuclear is extremely convenient

>>14704878
Two launches: an orbiter with a re-entry capsule and a lander with an ascent rocket

The lander drills a sample, puts it in the rocket, the rocket launches, docks with the orbiter, and transfers the sample. The orbiter returns to earth and drops off the sample with a high-speed ballistic re-entry using the capsule.

>>14704716

>>14704811
>-Mars due to dust storms (at least for early colonies)
This has been debated ad nauseam and it doesn't make sense. Dust storms reduce light but the vast majority of the power on Mars will be going into non-critical applications like ISRU which can be shut down for the duration of the storm. Even if critical applications could become jeopardized it would make more sense to send extra solar panels and a fuel cell or generator rather than a reactor. Nuclear on Mars will be exceedingly rare.
>Anywhere on the Moon that isn't the Peak of Eternal Light
A better use case as there's frequently 14 day long periods of no light on the Moon but the same idea as above can be applied. Battery energy storage is another option, it would heavier but probably cheaper. Beamed power would be far superior than any other option but ironically nuclear may be an easier sell because giant lasers r scary.

>>14704797
What difference does it make. People make it seem like the ISS is some Babylon 5 diplomatic outpost.

>>14704896
Oh, so all that to collect one sample?

Why not send 200 drones with those claw game flaws at bowling alleys and chukee cheeses to get much more?

The faggy race to get the first dust specs is chicken shit retarded compared to being the first to bring back 300 sampes of extreme variety

>>14704907

Work on .1% first. Then maybe, maybe struggle to work towards attempting .3%

How close are yall to achieving .1% c? And .3%? And .9%? And 3.4%?

Or you are skipping all those and going straight for +100% how close are you, what's the estmate time frame do achievment?

>>14704918
If you could fit 200 drones into a lander with a rocket and a retrieval system (that works) which is also guaranteed to survive EDL be my guest

Quelle surprise. I said yesterday there was no point rushing for anything. It was either bullshit or they wanted cash. The ISS is the one instance where Russia is still a peer on the world stage, they're not going to throw that away.

>>14704918
>>14704896
Even do that lander rover plan, with the 200 drones, to hopefully incease odds of success and variety, or that creates extreme logistical jeopardization with too much mass?

NASA was finished when it stopped doing things like this

>>14704953
The Apollo 12 episode of “From the Earth to the Moon” is great

>>14704941
>you go to the moon by working on faster and faster airplanes
Hows the working coming along? Anywhere near .1%? Or .3%? Or 10%c?

What's the eta of achieving 13.7%c?

How near are you, we, working on achieving 19.3% c?

When do you estimate we will achieve c?

Oh, and +c?

"Commercial drones can vary in price depending on the model of the drone and how many features it has. However, on average, commercial drones can cost anywhere between $500 and $4,000."

4,000 x 200 = 800,000

I geuss that would utterly break the back of your billion dollar a flight launches.

All the 100s of millions for this and that talked about in this general, and 800,000 to get 200 extreme variety samples from mars is obscene.

It'd probably be easier to explain if they showed the earth-moon relative motion because as I understand it they deliberately aim outwards and then let gravity change the vector into approximately lunar orbit by the time the system arrives there

>>14705121
Ingenuity was 85 million. If you take into account the gained knowledge, and less testing needed, probably around 25 million? It's definitely not as easy as just grabbing a commercial drone, souping it up a bit and sending it.

>>14705090
Universal rick roll

>>14705121
Anon why are you so mad?
The reason why you can't put a regular drone on Mars is because it has to be able to:
1. Fly in 1% atmospheric thickness of Earth's
2. Carry its own power source
3. Be able to survive the cold Martian night (~ -73°C)
4. Lift it's own weight in addition to the sample gathering device and sample
5. Survive long enough to make it back to a collection point to return the sample

If you wanted to fit 200 of those into a single mission, it'd cost you roughly $16 billion usd, based on the cost of Ingenuity. Add ~$200 million to that for operating costs.

To retrieve 200 unique samples of Mars it'd take you years with any affordable mission profile. The cheaper option for 200 samples is just a manned mission with a roving base. Though with that you can't return the samples until all 200 have been collected.

I wouldn't be surprised if the bumped rideshares from Psyche end up with them

>>14705029
I dunno, maybe somewhere under 200 years? I think the tech to do it will exist fairly soon (laser propulsion probably) but won't be large scale or well-funded for quite a while. Likely will be used to send small probes at blisteringly high speeds if I had to guess.
Current record stands at like 0.03% with chemical propulsion, and that was on a europoor rocket

Ok we gotta start somewhere. Was merely suggesting, yes, drones/copters may be better at sample digging retrieval than rovers and the chance to get more samples the better, by sending more than one drod hopefully.

I was providing bare bones extreme example with the hope it would motivate it being shot down, landing at less extreme example but still far greater than the least extreme example.

The drone alone. Keep in mind this includes design, prototyping, vacuum chamber time, testing, man hours etc. They weren't even sure it was possible when they started.

The entire perseverance mission cost ~2.7 billion.

>>14705154
>1. Fly in 1% atmospheric thickness of Earth's
How's that solved? Faster motor different propeller blade thickness, angle, weight?
Probably impossible
>2. Carry its own power source

>3. Be able to survive the cold Martian night (~ -73°C)
Large inflatable children's bouncy house is sent down and it has solar panels all on it that heat up during the day, and the drones return to it at night to sleep cozily.

But wait why are they there at night. They are all in the orbital, they are sent down to surface at the crack of dawn, collect their samples, return to mother ship before dark, those that don't make it sleep in the hot bouncy house
>4. Lift it's own weight in addition to the sample gathering device and sample
Probably impossible, the math nerds and simulations and vacuum atmosphere tests probably can't solve that

How hard and expensive is it to after you make 1, make 3 or 10 more?

Nah, their Neutron rocket is a huge step forward. The risk is already huge, considering the 16-fold increase in mass to orbit, building their first turbo pump and creating a rocket that is mostly reusable. Even SpaceX don't reuse their upper stage and they are miles ahead of everyone else. Maybe the next rocket after Neutron could be fully reusable, but a 90% reusable carbon-fiber rocket is already a first and a big game changer.

Targeting unrealistic goals is just a recipe for failure. Look at Astra's "daily launches by 2025" or the romanian "green rocket".

Chinese are more insect than human there aren't any redeeming qualities in that people. You just need to see a couple of clips where children are run over several times like they're dirt on the road, or the countless videos of animal torture on the streets like it's normal. They ruin all ecosystems they touch and selectively kill rare animals for magical penis powder. They're as subhuman as they come and even niggers are more tolerable as long as they stay on their continent.

Reminder that China can't land their rockets, and the CCP cares so little about the common people of China they don't even issue warnings before dropping rocket boosters onto people's houses.

I love china because they put roggets into space

I forgot to say which ones. The low quality Chinese food never makes me feel right after eating it. And a large old university near my home was a few years ago turned into a music school for Chinese, and one of my dreams for the past many years was to be a music composer and I am supremely special and gifted in this regard and I was too scared to try to approach them and try to let them help me, because I have social anxiety and can't stand to deal with the complex convuluted emotional energy of people

Was there ever a plan to have 2 SLS rockets built at once? Wasn't there some controversy over a second tower or something with the contractor not delivering?

>>14705502
The original hope was for up to three, maybe four, being able to launched per year. Now that’s down to a max of two.
The second tower - designed for Block IB - won’t be done until 2027, which pushes Artemis IV back to NET 2028

>>14704982

>>14705412
Don't bother having a moderate viewpoint, half of /sfg/ posters are amerimutts who only understand extremist viewpoints due to their fucked up political system. Threatening their american exceptionalism beliefs is haram.

Make sure you're at minimum safe distance.

>>14705502
>>14705506
It's fucked up that NASA actually figured out that they should have just kept using a heavy lift rocket, and that they should build them quickly and cheaply with suitable materials that they already have, but still let it turn into another slow expensive hellscape. Is SLS even better than the Shuttle? I guess, since the Shuttle couldn't land on another body, but fuck. Our launch capability is worse than it was fifty years ago.

>>14705520
It's substantially worse than the shuttle. The shuttle at least was an iconic design that became an international symbol of technological achievement. Action movies will still be showing space shuttle for decades. From an aesthetics and appearance standpoint, SLS is terminally uncool, a giant step back to the 60s.

Hating on the SLS family of launchers is un-American, bordering on treason

>>14705510
It's better to be an American and have an understanding of extremism, and therefore be able to choose the correct extreme positions, than be an intellectually neutered eurocuck, unable to even conceive of questioning his aristocratic betters.

>>14705524
In a way, I'm actually glad SLS happened. The idea that a derived launch vehicle would be quicker and cheaper to make than a clean sheet design has been a guiding principle of large rocket design for over four decades. Forty years of "here's another cheap rocket we could make using RSRMs and RS-25s!" Now we can point to SLS to show just how wrong that is.

>>14705541
SSSL is based.

>>14705544
>>14705541
For me it's the LSSS "Trident"

>>14705541
>hydromeme and solid rocket exploders
Yes, unironically too American. Thank fuck Musk came along and changed that.

>>14705486
The mars samples will of course be brought to a very secure sterile facility with no connection to outdoors at all, probably somewhere around wouhan if I had to geuss

>>14705547
SSSL could get off the ground though, 45MN of takeoff thrust. I don't think it's a good idea, but it would maybe kinda work.

Each SRB has almost double the thrust of the SLS liquid first stage, they make up 3/4 of the thrust while they're firing. Key takeaways, solids are based, and the F1 was fucking huge.

>>14704202
Next week is their earnings call. As a non-investor, probably the most excited I've been for one. I think Astranon said that the death of Rocket 3 would be announced in August, so this could be it.

kek I forgot he does that
probably the most notable thing so far is he said the company has 8x'd in head count since 2020 and they're at over 800 people now

>>14705555
SSSL is just a normal SLS with 3 boosters and the core air-starting. That'd actually make for a fairly impressive rocket, especially if you used RS-25 with more vacuum optimized engine bells. It'd be like some of the old proposals for massively overgrown Titan descendants.

Sticking the core on top of the boosters is a nightmare waiting to happen, but you might be able to make it not snap in half and fall over if you had the boosters standing in a tripod.

>>14705520
>>14705524
Some anon was giving me shit for my suggestion of 100-200 drones to dig samples on Mars as being too expensive

SLS is $2 billion per launch

>>14705541
I dont know anything about anything about the truth of all these rocketry regards, but there is nothing more unAmerican (and American) than wasting the people's tax dollars

>>14704970

lmao I'm tracking H.R. 4346 (they're still hashing out the final text of the bill in Congress)

No amendments to the NASA authorization so far, they're targeting biannual SLS launches. No money for any of this shit whatsoever but that's kinda okay because fiscal year 2023 starts in September and they have to pass a budget (lmao) for next year anyway

Worst case scenario NASA just laughs at Congress for giving them a goal that requires spending another two billion dollars a year and ignores the "goal" to launch two SLS per year

>>14705585
It's amazing how strong and assuredly tightly connnected that is, that the thrusting engines don't just fold the bottom in half and go straight through.

Must have been a lot of science knowing how to tightly and strongly connect all that? Or is it simple easy and obvious?

>>14705600
Finite element analysis is taught at the undergraduate engineering level at just about every university in the world my guy

>>14705571
Just because a position is extreme does not mean that it is incorrect. Rejecting "extremism" only benefits the ruling powers by allowing them to label anything that does not personally benefit them as extreme. Never ever compromise the principles that serve as the foundation of your philosophy.

>>14705599
>biannual SLS launches
Once again, congress decide to solve a problem by demanding someone do something that is physically impossible while providing no assistance in any form.

>>14705605
Still, some sheets of metal, nuts and bolts can withstand the force and power and acceleration and thrust of those rocket engines seems intuitively impressive to me, and not intuitively probable to function so like that.

Are there only a few certain metals that can do this? Do they have to really make sure everything is evenly bolted down and secure, one little mistake and then big structural integrity lack?

Starship isnt launching in August, is it

Also heres a cool wallpaper

>>14705613
The Saturn V could get an entire S-IVB upper stage with a full payload to the lunar surface if you didn't mind the landing being ballistic.

A soft landing would depend entirely on what kind of a lander you're using. The Apollo Applications Program had some interesting ideas for a 70s moon base post-Apollo 20, but none of them were very big. Most of them boiled down to having the Astronauts use a LEM taxi to shuttle to and from the surface while using a second oversized LEM as a cabin for the duration of their extended mission.

Constructing an actual moon base was generally understood to require the use of something bigger than the Saturn V; either the Saturn VIII or Nova or one of the other more outlandish post-Saturn V super rockets.

Starship is gonna be fucking huge at KSC

Wouldn't it be smarter to put Starship on the main pad where Falcon 9 currently launches from?

Also ETA to when we see a Starship on the cape?

>>14704679
>F9 was an expendable rocket that was autism rigged to land
Not entirely.
F9 was conceptually designed to be reusable from the beginning, but SpaceX focused on getting it to work first, then adding the landing ability. It wasn't a decision made after design started, it just wasn't incorporated from day 1.

>>14705669
This is a lie

Jeff pls

Is the mobile service tower still planned for LC-39?

>>14704708
The NASA mission is better because there will be samples of higher scientific value. The Chinese just want the "first mars sample" clout

>>14705657
I think SpaceX realized that building a pad from scratch isn’t any harder than refitting the normal pad. I am curious why it’s so close though.

>>14705657
>Starship alone is as tall as the launch tower
Holy shit bros. It's hard to conceptualise how big Starship is in the flat expanse of Boca Chica but next to this you really get how big it is.

Is Mars Sample Return a good mission or just another pork project?

>>14705351
>China has lost the space race
>doesn't actually explain how China lost the space race and just goes for low hanging fruit

He could have at least mocked them for having to buy their modern engines from Ukraine.

>>14705732
Yeah, but the Chinese don't buy foreign engines. They design and build all of their engines domestically, after stealing the plans for foreign engines and spending twenty years trying to reverse engineer the technology required to build them. If they were actually willing to buy foreign engines the Long March 9 would have been flying since 2020, if not earlier.

>>14705732
He explains that they lost it before it even began. They're decades behind and will stay that way because they have no real interest in it besides propaganda, and they figured out they can propagandize space stuff to their populace by showing them 3d renders instead of actual video footage of them doing stuff.

>>14705728
going up and down Venus's gravity well is hard & pointless. any realtime control of probes is better done from orbit

>>14705741
They have no drive. They have no vision. All they can do is ape Soviet and American accomplishments using technology stolen from the Americans and Soviets. They do it because they would feel inadequate otherwise, not because they have any true passion for the pursuit.

>>14705720
Yea its gonna be fucking huge

>>14705732
Tbh China isn't gonna launch LM9 until 2029-2035 (If the starship clone they teased is LM9 or a another rocket)

They wont have a heavy lift rocket until next decade so manned missions to the moon and deep space are out of the question for now. By then SLS will have flown 8+ times and the Starship program will be very mature.

Starship has capabilities no other rocket has currently and I wouldn't be suprised if blue origin/relativity make their own starship clone the second half of the decade

>>14705724
If you need rocks, just send a guy with a shovel. Maybe a spacesuit too, but I bet some SCUBA gear could work in a pinch.

>>14705745
They do have a vision, its just a very constrained one that they're pursuing in a very methodical manner. The biggest limitation for them right now is more budgetary than technological. Their space program has a fraction of NASA’s budget and given how deep it is in control of the military that budget has to cover all of their military space programs as well as their more public “civilian” space endeavors. They don’t have the money to really advance a lunar program while they’re also funding missions to a manned space station, but since their strategy is of the very unhurried one step at at time sort they don’t feel any need to try and rush both at once. They’ll run Tiangong for a decade or so to wring out whatever scientific or political value they can from it, then move on to the moon. Hopefully by 2035 their engine science will have caught up to the Long March 9’s perforce goals.

>>14705720
Is it starship standing on a massive booster, and the booster can return and self land?

>>14705724
>Is Mars Sample Return a good mission
Only if you get 20-200 samples from various locations, and deffinitly from those liquidy looking areas. Uhh yeah..
There may be microbes and shit
.
And especially if a digger driller can pierce like a foot or 10 down and grab some sample there

Also would it be the first time something went to mars surface and came back? Good practice for future missions and maybe it can drop off some usefil cargo in the process, solar farm or base building supplies, or can that stuff not just sit around or it will get full of radiation?

Have the mars rovers signal back their giger counter readings,?

>>14705784
Yea the goal is to be able to catch the booster with the chopsticks

>>14705747
Why is there so much hype about all these different rockets, they all seem to be able to do pretty much the same thing. Except starship can self land

>>14705805
They’re actually all pretty equal. None of them can launch!

>>14705805

>>14705830
/Sci/ is a shit board. It’s just race stuff, people bragging about IQ, and bait.

Could Relativity pull off building a Starship clone?

Would their 3D printing tech allow them to?

>>14705851
Terran R is a mini starship in all but name

>>14705851
Terran 1 has a diameter of 2.3m, and the printer that proonts it is the largest of its kind ever conceived. Terran R has a diameter of 5.5m, and Starship/Superheavy has a diameter of 9m. I'm not saying its impossible but they're going to have to take things one step at a time.

The real question is if a 3d metal printer that can handle 9m wide objects is in any way economical. Given the speed and cost that SpaceX is able to assemble Starship at using traditional manufacturing techniques, I'd say no.

>>14705860
I refuse to call it a printer. It's a mig tong stuck to a rotor.

>>14705864
I'm still convinced that Relativity is actually just a printer company that's using rockets as a means of advertising their stargate units and that they decided to do rockets instead of something else because a lot of them were exSpaceX employees and printing a rocket was cooler than printing a small jetliner.

>>14705830

>>14704681

>>14705851
>>14705860
Relativity hasn't pulled off a Falcon 1 clone, let alone Falcon 9 clone, if they're to pull off a Starship clone before either of the Falcon clones, it would be a miracle

>>14705830
How are they coping now that BASF is dead due to sanctions

>>14705307
to quote gregg easterbrook,
>Here's the plan. Suppose one of the solid-fueled boosters fails. The plan is, you die.

>>14705007
While you’re wrong on $4000 drones for Mars, you’re right that having unique robots for each mission is a dead-end. Once launch costs get significantly cheaper with starship we can plan to have a standard rover in sizes from 100kg, 1,000kg, 10,000kg and for gravities of 1-0.1g or 0.1-0.01g. That way we can have a finite set of choices and make TONS of them with massive economies of scale to make them cheap. You can also send them to many different planets and moons without significant rework.

>>14705876
Hence, one step at a time. Terran 1 is in the final stretch of flight prep, so we should should get an interesting launch stream in a month or so.

Unfortunately, its not about killing zombie companies.

GM went bankrupt and US tax payers lost ~$12 billion dollars. Now once more, they're getting $2.5 billion dollars in subsidies, along with more subsidies for their cars that they make in Mexico.

To be fair, 2028 is after 2024, and planning to withdraw from the ISS is reasonable at this point since we've been talking about our post-ISS plans for a while now. 2028 is the earliest ROS could get off the ground, and Borisov did say that they didn't want a hiatus in Russian manned spaceflight because it'd a complete case of ass trying to restart it after a gap of a few years.

So Terran 1 might be the first methalox rocket to achieve orbit.

Barely a month of science observations and JWST has already put the nail in the coffin of lambda-cdm, lmao

>>14707513
explain

>>14707517
The lambda-cdm model posits that the cosmological Constant, Dark Energy, Cold Dark Matter, and ordinary matter are the constituent components that result in the cosmic microwave background, the general structure and distribution of galaxies, the observed elements, and all the accelerating expansion of the universe. This model doesn't really work if large scale structure formation (galaxies, galaxy clusters, and star formation, ie the rionization epoch) happen sooner than 500 million years after the big bang. However, JWST has observed galaxies that appear to have redshift factors as high as 20, which is less than 200 million years after the Big Bang.

I had the same idea. The concept is brilliant

>>14707530
layman here. Yeah this whole early galaxy search has been kinda sus to me. You would expect galaxies to slowly form during the first hundreds of millions as the gas clumps together, instead what we see is just galaxies in a uniform universe

>>14707544
>>14707530
How do I learn about this stuff?

Funding for CLD is secured

also some of the observations show that the early galaxies are much smaller than the milky way. Are the early galaxies not supposed to be really big

>>14707530
What the shit, so the universe just started clumping together galaxies pretty much right off the bat then?

>>14707567
Apparently so. Nobody's in a position to say why, either, because all of the accepted models have basically been wrecked.

>>14707549
laymen here, I learned some of this stuff by watching youtube videos edging on pop-sci, which is a bad way to learn and a good way to waste time

>>14707567
either that or the galaxies were already there aka cyclical/big bounce theory is real

>>14707585

how cool would it be if we saw organised shit all the way then, it would kill off everything we think we know. Or if we saw anything existing before the supposed big bang.

Whoever it was that was asking about Artemis II progress, NSF has an update

https://www.nasaspaceflight.com/2022/07/boeing-second-sls-core-march/

>Mobile Launcher-1 needs a series of modifications for Artemis 2 that can’t begin until after Artemis 1 launches. It’s possible that Orion production and the Mobile Launcher modifications will be in work through the first half of 2023 or longer, so it may be necessary to store Core Stage-2 somewhere for months before stacking of the Artemis 2 vehicle can begin.

For fucks sake the mobile launchers were a mistake

>>14707692

Apparently this happens every once in a while in cosmology. Word has it these models arent built on the strongest foundations

>>14707567
>>14707583
How is 100 million years right off the bat.

Think about counting 1 year at a time and how long and how much humans can do in a year until 100 million.

As long as quarks and electrons exist, as long as the quarks bundled in neutrons and protons, and there were differing clusters of them..


I geuss it is weird how the clusters are so distant now in galaxies.

Like if everything started near.

Galaxies are clusters of clusters (a cluster of stars; stars are cluster of atoms)

Yeah that's pretty crazy

>>14707530
Seriously, why could there be galaxies so early? What could've caused that?

>>14707657
Humans measuring cosmogical time in years (the universally arbitrary time it takes earth to travel around the sun)

>>14707726
The Milky Way rotates once every 200 Million years, so seeing galaxies fully formed in just half that time seems pretty damn fast to me

>>14707738
God?

>>14707738
Nothing says galaxy formation has to happen on specific timescales

The thing that would really flip peoples lids is if the metallicity of the stars in those galaxies is any different than you'd expect

>>14707773
Which one?

The one of the Gaps

>>14707530
>This model doesn't really work if large scale structure formation (galaxies, galaxy clusters, and star formation, ie the rionization epoch) happen sooner than 500 million years after the big bang.
That is completely made up. Please cite this bullshit number. Galaxies don't just suddenly assemble at redshift 10, with absolutely nothing before. There is a growth curve so of course there are earlier objects. There is no one LCDM prediction for galaxy formation.

>>14707544
We do see galaxies slowly form. Which is why the most distant galaxies are far less massive than today's galaxies and they are more metal poor.

>>14707657
>how cool would it be if we saw organised shit all the way then, it would kill off everything we think we know. Or if we saw anything existing before the supposed big bang.
The redshift factor at 380k years after the Big Bang is over a thousand. Everything that early in the universe is deep in radio.

>>14707814
>That is completely made up. Please cite this bullshit number.
Here's NASA's LCDM chronology.

>>14707848
A drawing is not a technical source. Note there that the first stars aren't even labeled. Do you really think it makes sense that glalxies form exactly at 400 Myra and then immediately start reionisation?

>>14707815

New bread

Posted here earlier good interview.
https://www.youtube.com/watch?v=NgT4JOJMaqQ

>>14707868
It's not about starting exactly at that point, it's about the input factors that produce the cosmic microwave background and the structure and distribution of galaxies out of primordial stellar gas using only "known" physics to get the universe that we see today.

>>14707848
>>14707816
Since you've failed at providing a real source here are some papers of LCDM simulations predicting galaxies detected by JWST before 500 Myrs.
https://ui.adsabs.harvard.edu/abs/2020MNRAS.499.5702B/abstract
https://ui.adsabs.harvard.edu/abs/2022arXiv220409431W/abstract
https://ui.adsabs.harvard.edu/abs/2018MNRAS.474.2352C/abstract

>>14707897
Well you've done better than me on that front, but the sources given still make the overall point I was looking for:
>Our predictions suggest that in JWST's first cycle alone, around 600 galaxies should be identified at z>10, with the first small samples available at z>13.
Galaxy candidates with Z~20 wasn't exactly expected.

>>14707745
Would galaxies nessecerily have started off much more compact?

Think of the proton, neutron and electron scale.

Clusters of these seperated from clusters of these (they would become the galaxies)

They are small and would have been in close proximity. Then in these proto galaxy clusters
100 million atoms here, seperated by a relatively small distance with 100 million or quadrillion atoms over there seperated by a relatively small distance with 100 trillion billion atoms over there et etc

Formed the seperate stars of the Galaxy.

If everything starts close together at first;then even the stars of galaxies were likely close together at first;

And then as they sheded em energy, and gravity worked, they actually spread out?

Or could it have been there was a class of stars early in the universe that were all big and close together in galaxies, and they all exploded info smaller stars spreading out a greater distance in the galaxy? Ding ding ding?

>>14707739
>Humans measuring cosmogical time in years (the universally arbitrary time it takes earth to travel around the sun)
This really is or actually may be quite absurd.

The possible varying different rhythems of cosmological epochs of universal construction may though kinks in measuring it's absolute rate of change consistently in earth years.

>>14707814
>Galaxies don't just suddenly assemble at redshift 10,
The stuff that makes up the galaxy was moving as a cluster since the start

>>14707913
Candidate=/= confirmed.
And the other point I was trying to get you to understand is that there isn't a single prediction from LCDM on when the first stars should be. That is because it depends not just on cosmological things (dark matter, structure formation) but on complicated astrophysical processes (zero metal star formation, gas cooling, feedback). These things are too complicated to simulate directly, so people make recipes. There is no one accepted way to do that, and so different modellers get different results. If you do a higher resolution simulation or a bigger simulation volume you will get earlier galaxies.
There is no single age at which you expect nothing before than, that was what you said and it is not correct.

>>14707928
An isolated cluster is just a low mass galaxy.

The L3M lander was the final N1 launched Soviet design for a lunar lander. It superseded the LK single man lander as it could hold two crew. It was a dual launch vehicle, with a first N1 carrying a hydrogen-oxygen transfer stage, and the second carrying the L3M.
Most interesting is that the L3M was pretty much just a vored Soyuz.
