Landspace has some plans for future rockets that I find quite interesting.

They're developing the ZQ-3 and ZQ-4. The ZQ-3 will be a Falcon 9 style rocket, except it will be mox, 4.5m diameter and made of stainless steel. NET 2025. The ZQ-4 will be a Starship style rocket, and they're working on a Raptor style 2MN FFSC mox engine for it. Targeting 2028.

https://spacenews.com/landspace-launches-third-methane-zhuque-2-targets-2025-launch-of-new-stainless-steel-rocket/

(linking their Chinese language version of their website because the English language version has not been updated with the ZQ-3 yet)
https://www.landspace.com/product.html?mao=1

I was reading some comments online that ridiculed the idea of a Falcon 9 style steel rocket as blindly aping SpaceX's more recent design choices for Starship and applying them to the wrong rocket. Yet I think there might be logical reasons for the choice, and I wonder what others think.

1. The 4.5m tank diameter is unique in China. I assume they need a 9-cluster of engines because the TQ-12 can't throttle deep enough for a 7-cluster. So maybe 5m was too big and 3.8m was too small. A unique tank diameter production line might require high capex. With steel, they lower that capex. And since the ZQ-3 is only intended to be a brief stepping stone to the ZQ-4, they don't want to overinvest in its production line.

2. The ZQ-3 is likely mainly intended to launch the Guowang constellation. The payload capacity might be volume constrained rather than mass constrained because of the stacking and dispensing mechanisms, so there's not much point in mass-optimizing the rocket.

3. They get experience with stainless steel and mox that will be useful for the ZQ-4

>>15917455
why cant chinks ever invent an original thought? theyve gone from doing soyuz ripoffs and struggling to do basic iterations on that, to doing falcon 9 and starship ripoffs.

>>15917478
the europeans are trying to be original, its not working
why not copy the best first, then start iterating?

>>15917455
>starship style rocket

So that’s like, 3 or 4 starship clones from China coming online next decade

Stoke better make a super heavy vehicle after nova is done

WE SHOULD TAKE STARBASE AND PUSH IT SOMEWHERE ELSE!!

can someone please educate me on the stink that is spaceX being pioneered as this top class space company thats able to launch a kg of payload the cheapest out of all the choices out there with a success rate lower than 20%?

he rehashed old soviet technology, did it worse and cant even payload his own feces in leo

Landspace is a for-profit company that has to answer to its investors, so they are obviously more inclined to follow the proven path than to put money into realizing engineers' unproven napkin scribbles. Especially when there is no Falcon 9 or Starship in China yet, so that field remains wide open for them.

Wild ideas are more likely from CASC and CASIC. They have a licence from the state to put money into risky experiments that are likely to fail, and they also develop for the peculiar requirements of the military. So they have projects that include
* air launched liquid reusable rockets
* a VTHL TSTO spaceplane
* Tengyun, a HTHL TSTO spaceplane using combined cycle engnes
* CZ-10A, a Falcon 9 style rocket except using ORSC engines and landing using wires
in addition to their more conventional rockets.

Still, Landspace's ZQ-3 is hardly a Falcon 9 ripoff. It is only similar on a conceptual level; the detailed design choices are different. This compares with for example Galactic Energy, whose Pallas-1 rocket is far more similar to Falcon 9. They even explicitly brag on their website that their Welkin engine is intended to be a Merlin clone.
https://www.galactic-energy.cn/index.php/En/List/cid/18

I think Landspace briefly considered a spaceplane called Qinglong, then decided against the idea

Which are the 3rd and 4th? I only know of two Chinese Starship style projects. One if CASC's CZ-9 using the in-development 2MN FFSC mox engine. The other is Landspace's.

Although, it would not surprise me if CASC makes two competing Starship style rockets based on the same engine, one by CALT and one by SAST, just like both CALT and SAST make similar competing rockets based on the YF-20 and YF-100 engines e.g. CZ-2C vs CZ-2D, and CZ-6A vs CZ-8, ensuring a degree of competition even within the SOE ecosystem. Nor would it surprise me if other Chinese companies also intend to follow the same path.

Is there a nontrivial risk that the Chinese manage to land people on the moon before the US can get back?

While the American program is nominally ahead in schedule, the American program seems to involve more technical complexity and thus risk than the Chinese one, with the large scale in-orbit cryogenic propellant depots, high-teen number of launches within a brief timespan to avoid boiloff, the capable yet unprecedented cryogenic gigalander, etc. GAO said Artemis 3 is likely to slip to 2027 due to both the suits and the lander. The Chinese are targeting 2027 for the first test launch of their moon rocket, and have been vague about when exactly they intend to land people, just saying "before 2030"

Time margins that tiny seem like a major risk. Because if the commies are uploading TikToks of themselves golfing on the moon while American astronauts aren't, a nontrivial number of 'Muricans might just off themselves out of embarassment. There ought to be political fallout.

>>15917657
It's 100% at this point. The US is pursuing very audacious plans to land on the moon, with reusable landers and multi flight missions and all the rest of it, but Chinks are making a rip off of apollo which is far easier to develope.

Either lying to himself or doesnt know a single thing about how his *potential* customers may think. They will take the thing that has the best flight record (SpaceX) and cost (SpaceX again and soon Starship once its reliable). why would you ever risk your extremely valuable payload on some new faggot launch company other than to stick it to the Felongated Huskyrat because he wrongthinks online (which literally never happens see Astra).

>>15917787
>我们的太空

>>15917806
Gilmour doesn't even aim to compete directly with SpaceX it seems. Rather they are aiming for the "small payload to unique orbit precluding rideshare on bigger rocket" niche

If they are aiming to compete with SpaceX, they'll have to join the queue behind Blorigin, RocketLab, Relativity, etc

>>15917815
Meanwhile China's Mars sample return is a two-launch architecture that's brutally primitive. No aerobraking the lander, it's an impactor. It drills at the landing site and launches to rendezvous in orbit.

>>15917791
>and the most recent 100 missions in only two years.
If SpaceX didn't exist, and we had only oldspace as a comparison, that would appear genuinely impressive.
But since it does, we see a whole-ass country that likes to think of itself as a world power, getting mogged 2:1 by a private company that actually focuses on spaceflight.

>>15917793

Coco is a big fan of American space, like the good patriotic girl she is.

>>15917847
We also had multiple other small launch companies that were way the fuck cheaper than oldspace that went under because SpaceX was cheaper/better still. That's the other part of why China is so afraid of burgerspace, the industry surviving the winnowing of failed smallsat launchers means that capital and expertise have now diffused all over, like how the dot-com crash kept Silicon Valley going for another quarter century.

>>15917877
They wont be able to compete with SpaceX 2.0 either

>>15917808
>its going to be obsoleted by a human mission in the near future anyway
Yet China will launch a Mars sample return in 2028, returning 2031. Don't the Americans need something that'll let them get Mars rocks back first, or at least simultaneously? Can America really allow a Martian rock gap, no matter how small or temporary the commie lead might be?

>>15917884
If there are two or more SpaceX's, then you can go to the other if one is finding excuses to refuse to launch your payloads, or overcharges you, or is being deliberately sluggish causing you to miss a launch window or regulatory window, or if you are afraid they'll inspect your payloads to steal trade secrets that'll give them a leg up for their own competing product line

If starship works wouldn't it mean the end to any kind of possible competition?

>>15917964
F9 already does that so not really anymore than now at least for a number of years
but Starship is going to be paradigm changing

>>15917964
At least Jeff Bezos will certainly fund the development of a Starship competitor for the US market

>>15917974
He already is funding an HLS competitor.

>>15917964
The only competition will emerge in China where there is not yet a Starship like vehicle. There will continue to be Blue Origin grift on the margins living off DOD contracts, they will absorb ULA's market share.

>>15917990
Honestly this is part of why I'm cheering for the QI memesat, if it scales up to megawatts then beamed power launch becomes way more viable.

It's small BECAUSE of the retarded orbit. Lunar polar orbits like NRHO lack a free return trajectory so the wheezy little ICPS can't put a proper CSM-sized payload in it. A larger service module would have meant canceling ICPS and delaying Artemis 1 until EUS was ready.

Why make it bigger, if it already works as intended? Also, bigger service module with more parts would require another few hundreds contractors, each of them getting paid at least one million dollars.

>>15918003
SLS delenda est

>>15918000
Better question: why did they make Orion so fat? Orion CM is 10,400kg, Apollo CM was 5,560 kg

>>15918023
Radiation shielding. Apollo's radiation protection plan was to cross your fingers and pray very hard there wasn't a coronal mass ejection that day.

I started thinking about how to apply more delta-V to Orion without cutting mass from the command module or the crew and it converges pretty quickly on Starship: reusability, refueling, integral tanks and propulsion with unified TPS rather than a detachable capsule, bigger for better mass fractions. We have reached the end of oldspace design philosophy unless someone pulls a QI rabbit out of their hat and propellantless electric propulsion becomes viable for vacuum-only spacecraft.

>>15918023
Orion capsule is a lot bigger and more spacious inside.

>>15918024
Wouldn't the most effective shielding be to orient the spacecraft to put the service module between themselves and the sun? Or doesn't that work because the radiation vectors are warped by the Earth's magnetic field and thus comes at the spacecraft from several directions?

>>15918010
You don't need more parts to have bigger fuel tanks

Would this be a good replacement?

>>15918033
it's more that without magic QI thrusters you burn a fuckload of propellant doing that and it makes maneuvering harder

>>15917836
>Stir fry chinks in a wok

>>15918034
You don't need bigger fuel tanks if you have enough Δv.

>>15918035
Someone call Starbase

>>15918048
Translator's note: Orion does not have enough Δv.

>>15918039
Does it really consume that much RCS propellant to slowly rotate the spacecraft a few times? I assume they wouldn't have to rotate particularly fast.

Don't they do such maneuvers for docking and reentry anyway, with RCS propellant margins to spare?

>>15918054
It's not like a circular orbit in LEO where your angle to the sun is constant for a given inclination+latitude+longitude, your trajectory to the moon is itself rotating around the Earth and so the sun angle is constantly changing in multiple dimensions.

>>15918052
It has enough to get to NRHO and back, that's what it's designed for.

>>15918035
just put some mud over Starship, why didn't they think of this

>>15918061
They're mass limited rather than volume limited for moon rock samples they can bring back, so no, it does not have enough Δv.

>>15918057
Can't you just put the spacecraft into a very very slow rotation at an angular velocity that matches how the incident angle of the sun is changing, making tiny adjustments whenever it becomes necessary?

I suppose you can't do it when you need to do a burn with the service module main engine, however if that doesn't happen very often or long, then is that really an unacceptable amount of extra radiation astronauts would get exposed to during those seconds

>>15918072
The prop tanks aren't big enough to be shields on Orion anyway because the CSM is so small.

it amuses me when people act like Artemis 3 SLS + Orion + Suits will be ready before Starship HLS. Worse case it will all arrive at the same time. More likely HLS will be first to completion. Launch will be 2029

They could be bigger if Orion wasn't so fat, so that seems like circular justification

>>15918082
Orion still needs to be big.

HLS will need to get to LEO anyway, for refueling between landings, so it could be used to bring more samples and other stuff that could be loaded to a Dragon capsule or another SS and brought down to Earth. Though at this point Orion becomes totally unnecessary.

>>15918086
>Though at this point Orion becomes totally unnecessary.
That's why nobody is proposing using HLS for return to LEO, it makes the scam too obvious.

>>15918087
It doesn't have enough dV.

It would if it had TPS for aerobraking.

Which company/organization other than SpaceX will be the next to successfully land a booster after an orbital launch? I assume it will be American or Chinese.

I know at least 2 American and 3 Chinese companies intend to attempt a first launch of a reusable rocket in 2024
* Blue Origin
* RocketLab
* Space Pioneer
* Galactic Energy
* Deep Blue Aerospace

>>15918094
Do hobbitlab's parachute recoveries count? If not I think it'll be Stoke Space.

>>15918039
>>15918072
Alternatively you could maybe use reaction wheels like many spacecraft do

>>15918099
Reaction wheels don't scale well to manned spacecraft which is why capsules, the shuttle, and space stations don't use them.

Vulcan more like Vulcan't

>>15918094
India's got plans but they're a ways off

>>15918097
I meant in the sense of propulsive landing, or at least a booster recovered in a way that, at least in theory, allows full reuse of the whole booster, which I don't think RL's method does, due to landing in salt water

Has Stoke Space given a target date for their first launch attempt?

>>15918094
probably blue origin, but they're moving like pitch so idk

>>15918106
are you drunk? they are launching now.

>>15918106
>Has Stoke Space given a target date for their first launch attempt?
No, but they're the only ones who have hopped.

>>15918100
Don't space stations including Salyut, Mir and ISS use so-called gyrodynes or control moment gyroscopes?

>>15918112
no

>>15918109
on the subject of launching now, when is the x37b falcon heavy going up?

>>15918112
they use rcs

>>15918106
RL could be able to reuse more of their booster than SpaceX, since Falcon has a few parts in the landing gear that need to be swapped out after each flight. Refurbishment from a salt bath will fuck with this somewhat, but RL did say have some optimistic sounding things to say after their recovery tests.

Stoke is planning for a 2025 launch date, but that's going to slip at least a year.

>>15918109
Do you mean hop test or orbital launch? If the latter, do you have a link? I can't find it

>>15918118
replacing crush cores in landing legs is easier than landing in salt water. if you get salt water in the engines they are fucked, and at the very least they have their lifespan severely reduced. One of the Falcon 1 failures was because of salt water corrosion on the engine, despite the fact that it was never submerged in the water.

Speaking of non-reusable landing legs, Catching the Starship with the tower for Earth landings is genius because the landing legs on Starship will probably not be able to land more than once without crush core replacement

>The preferred method of attitude control is the use of Control Moment Gyroscopes
(CMGs), sometimes called gyrodynes in other programs, mounted on the Z1 Truss seg-
ment. CMGs are 98-kilogram (220-pound) steel wheels that spin at 6,600 revolutions per
minute (rpm). The high-rotation velocity and large mass allow a considerable amount of
angular momentum to be stored. Each CMG has gimbals and can be repositioned to any
attitude. As the CMG is repositioned, the resulting force causes the ISS to move. Using
multiple CMGs permits the ISS to be moved to new positions or permits the attitude to
be held constant. The advantages of this system are that it relies on electrical power gener-
ated by the solar arrays and that it provides smooth, continuously variable attitude control.
CMGs are, however, limited in the amount of angular momentum they can provide and
the rate at which they can move the station. When CMGs can no longer provide the req-
uisite energy, rocket engines are used.

starship can probably land on the legs multiple times.
the reason falcon needs them is the 1 engine at minimum throttle still gives it a twr >1 when landing, so they HAVE to come in hot; I'm not sure what the min. throttle for a raptor is but a reusable starship with all the thermal tiles and stainless body is absolutely going to get the twr below one, so they won't be forced into the hoverslam/suicide burn bullshit that necessitates crush cores.

>>15919039
Starship dry will be much heavier than falcon dry so it will impart more force on the legs for a given landing speed. Granted its easier to land slow if you can hover, but it won't be able to hover in lunar gravity and probably not in Mars gravity either. It won't have access to GPS or droneship guidance so that will eat into the landing precision also. On earth the legged version if Starship may be able to touch down without damage to the legs, but for Earth to LEO they won't use that version

>>15919039

I don't know how to read TLE's, but testing was supposed to start ***about*** a month after launch, it has been in orbit for 1 month and 1 day now so if it's gonna rise it should start soon.

>jews are colonizers
>they're also anti colonizers
is this 4D or 2D chess

How would you optimize an Earthlike planet for maximum livable surface area and comfiness? Bonus points are awarded for diverse climates and ease of access to space.

I imagine mass, density, irradiance, albedo and surface water would be the most important considerations.

>>15919239
blow it up and use the mass to construct a massive number of O'neill cylinders with diverse climates, access into space is as easy as just walking a bit into one direction

When a Jew says "anti-colonizer" they mean they want nonwhites to colonize white countries.

yes but it's a function of how fast you're moving in relation to the speed you were already going
the bigger the cylinder the faster you move for a certain gravity

>>15919315
no lol

>>15918988
Because most of that footage was collecting dust and rotting away in archives and nobody cared digging them up. The N1 documentary baguette was getting his hand on new stuff but the war might've messed the timeline up
