Why do you only ever really see one spin hab on ships, doesn't it make more sense to have two? If you have one to counterrotate against you can spin up with a motor without affecting the positioning of the central shaft. And you don't need propellants and it can act as a big flywheel for energy storage. Are there physical gyroscopic effects I missing?

That's not what the paper is about. They present an argument from abundance patterns that elements above uranium are partially products of fission of even more massive nuclei. Indirect evidence that the R process in supernovae creating neutron rich super-heavy nuclei beyond atomic masses of 260, which quickly decay. It's actually a nice test of the standard picture of nucleosynthesis in supernovea.

Oh look more irrelevent bullshit. Reminder that Herouni never measured no CMB. The CMB is definitely real and not local. The fact that galaxy clusters leave shadows on the CMB proves it is more distant, and this is definitely the case as hundreds of new galaxy clusters have been found this way.

an argument for a single centrifugal habitat would be that counterbalancing it with a regular (uninhabited) gyroscope gives you more options for manuevering than counterbalancing it with another habitat.
say you want to stabilize or change your craft's attitude quickly, and you want to use gyroscopes only, because electricity is free and fuel is not. If all of your flywheels are also habitats, you can't rapidly accelerate or reverse their rotation, with a gyroscope you can. I reckon that even gently utilizing a rotating habitat for attitude control would be nauseating for the inhabitants, so ideally you want a gyro anyways.
one gyro and one rotating habitat would be more minimal than two habitats and an additional flywheel for attitude control.

not even fast changes, even slight changes in attitude on a ship like >>15928130 would surely require a lot of force, since the engine and fuel tanks are far from the center and look heavy.
if a gyro wheel somewhere else on the craft rapidly changes its velocity, thus slightly affecting overall attitude, the people in the ring would only notice a slight attitude change.
if the habitat spins to achieve the change in attitude, there would be a potentially rapid acceleration directly on the habitat itself, as well as the same change in attitude.

I just realized something about New Shepard that's wasted design. Since the legs of the first stage have to support the landing mass of the entire stage + residual fuel, the total mass of that is probably equal to or greater than the weight of the capsule (fully loaded). Which means that they could have reversed the meca-shift legs they deploy during the landing sequence and used them to hold the capsule up and then when the capsule disconnects near the karman line, those struts would recede back into the core stage. Instead, they have extra struts that holds the capsule like a crown, and is an added sub assembly to the process--which increases complexity all around.

it's important to keep the extremely low power usage in mind when comparing it to an existing ion engine.
the current best state of the art thrust per watt for an ion engine would be producing roughly 0.001mN of thrust per watt or about 1000x less mN/kW; and, it would also have a limited fuel supply.
That is of course assuming the schizodrive actually works to begin with.
I think the efficiency numbers are the hardest pill to swallow for me, moreso than the entirely-new-domain-of-physics relying on virtual particle bullshit. 1 millinewton per watt is retardedly good already, but McCulloch claims it could even do 50x more than that at 52mN per watt. If that's real then forget about any other kind of propulsion for anything beyond surface-to-orbit for deep gravity wells like earth. don't even bother with nuclear thermal, solar electric schizodrive would rape it all the way to the kuiper belt

52 millinewtons is equal to .052 newtons, multiply that by 3000 (a few thousands) and you get 156 newtons. That's equivalent to 156 apples falling from a tree onto Newton's head.

>“Our good friend Frank Rubio, who headed home [on September 27], has been blamed for quite a while for eating the tomato. But we can exonerate him. We found the tomato.”

What are the advantages and drawbacks of air launch? I get that there are structural difficulties with hanging a fueled rocket horizontally, and having a plane as launch platform restricts the rocket in size and adds cost and complexity to the system as a whole.
LauncherOne doesn't seem to be going anywhere anymore. However, China's CASC is supposedly working on a reusable air launched liquid propellant rocket. What would be the reason? I assume it is for military requirements.

I think
(1) You can launch in almost any weather
(2) You can turn any airport that has a cryogenic air separator nearby into an orbital launch site, even airports not located in places suitable for your target orbit. It becomes even more convenient if the rocket engine can run on regular jet fuel. So you immediately create up to hundreds of launch sites in the country without having to build any ground infrastructure

USSF say they think China's CZ-5B marginal cost of launch is $3,000 per kg payload.
Isn't Falcon 9 $2.7k/kg? SpaceX's internal pricetag might be lower, and the marginal cost is certainly lower, however the Chinese price tag estimate seems to be in the same ballpark.
China wants to mainly rely on the CZ-5B and CZ-8 to launch their Guowang constellation. They intend to ramp up CZ-5B launches, and launch 50 CZ-8 and 10 CZ-7A per year. CZ-5/7/8 are all CALT rockets. Historically, SAST has been responsible for about 40% of CASC rockets. So I assume SAST will produce a comparable number of CZ-6/6A/6C. The Shanghai municipal government mentioned plans to build 50 商业火箭 "commercial rockets" per year starting in 2025.
If the $3k/kg price tag is true, it makes sense why they think they can rely on the CZ-5-8 to launch their Guowang constellation and why CASC isn't too hurried with the reusable CZ-10A. They get reasonable price while maintaining the schedule predictability that comes from relying on proven conservative technology, while other Chinese companies can hurry chasing a Falcon 9 equivalent. CZ-5B is 8x YF-100 + 2x YF-77 for 25,000kg to LEO. CZ-8 is 4x YF-100 + 2x YF-75 for 8,100kg to LEO. So CZ-8 might have a similar price tag per kg.

You can't hit that pricetag on an expendable without tradeoffs. What's the catch? The cost of labor in China is certainly low, but that can't be something that makes qualified rocket scientists and aerospace engineers happy, and CASC hasn't been building very many CZ-5s.

He's talking about the marginal cost, not total cost, so fixed initial costs e.g. R&D and tooling are not included in that price tag.
Although, in many cases marginal cost can decrease even more if production rate increases. While the CZ-5 hasn't launched a lot yet, it shares the YF-100 engine and 3.35 tank diameter with other rockets. There's also probably various general things it shares with China's launch industry in general, such as computers, valves, sensors, etc.

China is building and launching expendable rockets at a rate by a single country not seen since the days of the Soviet Union. Given their plans, that are already working on implementing, they are likely to surpass the USSR soon, both in number of launches and in mass to orbit. China probably has a great deal of streamlining and economies of scale in the industry, wringing out the lowest unit cost possible.

Even when components aren't the same, the facilities and machines for making, storing and transporting them and their components might be
Some things that might perhaps have a great deal of commonality, that I can think of:
* General overhead that exists in any organization
* Various storage, production and transport facilities of AALPT, CAAET, and CALT
* Tank diameter and its production facilities
* Electronics, sensors, telemetry systems, ground stations, and the means of their production and operation
* Fairing production facilities
* Most of the materials, even if not all
* The second stage of CZ-3 are hydrolox like the CZ-5's core, and the stage is common with CZ-8 and 7A
Often institutional streamlining can come from doing similar tasks often and for a long time, because everyone knows what they are supposed to do, and who to call when something irregular happens that threatens to disrupt operations. If there are many people with every relevant expertise and knowledge, then no one employee retiring or quitting ever causes disruptions.
When you have many similar projects going on, rather than just one or two projects, you seldom get the case that you have employees with nothing to do related to their special expertise, that you have to keep on payroll anyway because you'll need their special expertise in two years and it would be hard to get them to come back if you fire them

I'll give you the booster tankage, the CZ-2 and CZ-5 have common diameters there where some economy of scale can be leveraged with kerolox being a more benign counterpart to the absolute sack of toxic hell that is UDMH and N2O4, but the CZ-5 core is an entirely distinct asset and its own bag of trouble.

The 3.35m diameter is likely chosen because of benefits of commonality with hypergolic rockets. Kerolox rockets launched from Wenchang travel by boat from Tianjin, no? They don't strictly need to follow railmax constraints

Yet he's talking about marginal cost, so it's clearly an USSF estimate of the costs of inputs, he's not citing any list prices. Unless you mean the basis of the estimate is that the NSA hacked CASC and found a document that mentions marginal cost only to the extent it impacts CASCs own balance sheet while ignoring massive subsidies, and both the NSA and the USSF was fooled by it

This: Orbital Sciences claimed avoiding weather delays was the biggest advantage for Pegasus. Also there is a lot of mission flexibility because you can optimize for different orbits depending on the latitude and direction you launch from.
The 747 was a great choice because it had already been engineered with a fifth hardpoint, originally used for carrying spare engines between the factories and airports. Pity it no longer makes economic sense, it would have been a great competitor for Pegasus decades ago.

I think one thing that might make CZ-5B and CZ-8G even more cost effective is fairing size. Guowang payloads are likely volume constrained rather than mass constrained due to stacking and dispensing mechanisms. So it might be misleading to merely consider and compare kg to orbit

There is no way dark matter interacts so strongly that it forms or is bound in asteroids.
The mostly likely explanation is just measurement errors. If you take a large enough dataset you will find extreme outliers just by statistics. That's ignoring real errors which happen in research (values misprinted in tables, objects measurements swapped...).
>>15930079
That is deranged. They do a huge mental backflip in declaring that dark matter cannot be baryonic, but maybe some of it could be if there are lots of types. In which case what your looking for is totally irrelevant in the big context. Furthermore without a density you cannot rule out any model ever, you can always just assume the density is lower and lower to avoid detection. If you don't require the dark matter candidate to make up the whole density you can just explain nondetextions by scaling that component lower and lower.
I work in the field and I have never heard of this idea. It is pointless. Those slides are like the brown scribbles on the asylum wall.

Don't worry about it, a guy well versed in environmental regulations but with a blind spot for Musk companies' ability to slip through every crack and loophole there is and self-admitted EDS. I recommend reading his blog if you're legitimately interested in how all this regulatory stuff works, when he actually explains stuff he does so quite well, but you have to be able to not get triggered by the Musk criticism, so not recommended if you cannot fathom Musk ever doing anything wrong.
