Some news from a Ruskie telegram

Russia offers BRICS partners a module on its planned space station

Russia's space agency suggests BRICS partners (Brazil, India, China, and South Africa) collaborate on a module for its planned orbital station.

The first module of the Russian Orbital Station (ROS) is expected to be launched in 2027, with construction completed by 2032.

The invitation aims to utilize low-Earth orbit for the BRICS countries' national space programs.

"I would like to invite BRICS partners to ... create a fully-fledged module that, being part of the ROS, would allow the BRICS countries to use the possibilities of low-Earth orbit to implement their national space programmes," Interfax quoted Roscosmos Director-General Yuri Borisov as telling the meeting.

The ROS will consist of six modules and a service platform, accommodating up to four cosmonauts, and will be built in two phases. It will orbit Earth around the poles, providing enhanced observation capabilities for Russia's vast territory and cosmic radiation research.

This technology could enable robust construction on the lunar surface to advance human and robotic operations, paving the way for a sustainable human presence and a dynamic lunar economy.

> By using local materials to build infrastructure, this new technology would reduce the cost of sending construction materials to the Moon. Redwire’s cutting-edge manufacturing technology will use a microwave emitter to heat and solidify regolith (lunar dust and crushed rock) to construct landing pads, roads, foundations, and dust mitigation surfaces.

The process to make it seems pretty artisanal, I wouldn't be surprised if doing it better increases it's critical current. Or maybe we find new similar and better superconductors through iterations on this one.
Or it's a dead end and it will end up on the list of record breaking semiconductors with all of the other commercially irrelevant ones, we'll see

>>15588099
the fact that they're looking to problems with application instead of if it's RTP claim is fake or not gets me kind of pumped for the future. transistors used to be extremely shit too, we might find better materials to create teh same effect, better manufacturing processes to make it more potent, really who knows

also, did you know that french guiana has a launch pad for soyuz? they flew like 20 missions out of korou before roscosmos pulled the oneweb shit and got banned from european spaceflight, which extended all the way to brazil - the great irony being that their last launch from korou was for oneweb too. so at one point it was theoretically feasible for russia to get a soyuz up to the chinks, if only they had the ground support for crewed launch. at this point though nothing less than putin's death could save russia from losing manned spaceflight entirely; a real shame since they were such a significant player in space and were even arguably ahead of the US in the early 2010s

>>15588694

>>15588689
I still don't know the plan for orbit refilling. Everyone says they'll induce spin of the crafts, but how much propellent will that take? They're heavy as fuck, couldn't be a small amount. And then the mating points; they'll have to be strong to keep hundreds of tons of metal from not tearing away from itself.

It's not physically impossible but I'm interested in the numbers on their solutions, as it pertains to dV with more mass or more propellant to make it happen.

>>15588699
>Everyone says they'll induce spin of the crafts, but how much propellent will that take?
negligible amounts

>>15588696

How is liquid ammonia and NO2 as a propellant mix?

>>15588699
what this guy said
>>15588703

The delta v is m/s (no k). It's going be to less than the difference in fuel used getting to orbit for two nominally identical launches.

>>15588731
No shit, but we're talking the spin of a combined 400 - 450 tons of mass that can push the propellant to the outer wall, with enough pressure for pumps to be effective anyway. And then to slow down and do it for each refilling to the tanker.

Just a curiousity of mine. I've not toyed with simulations in a long while

I think hot staging is retarded. I think spin staging was only slightly more retarded. I do not think they will be able to have both hot staging and booster reuse. I think they realized too late that spinning was retarded, and didn't have time to design ullage rockets without halting progress. I think spacex will eventually abandon hot staging, just as they abandoned spinning, and musk stans will immediately forget their first two miss steps.

>>15588743
I think your English is improving but still needs work

>>15588652
Obviously because they intentionally underestimate the robustness - giving an absolute worst case figure for every single design goal - such that anything other than a catastrophic failure of the landing system will be taken as a complete success. This then also allows them to repeatedly claim that they've exceeded mission expectations, which makes the exorbitant cost of each mission at least somewhat palatable to congress and the public. If JPL was actually designing rovers as flimsily as they claim they wouldn't need even a tenth of their current funding. JPLniggers really want to spend 30% of the US GDP to get a few milligrams of orange dust back to earth over the course of two decades and 5 separate missions, and they really think there's nothing wrong with that. God willing, the OIG will enact a pogrom on every JPL employee and their descendants.

They'll probably try pushers before they try ullage motors. That said, they've put an awful lot of effort into ullage volume based cold gas thrusters, but they clearly don't want to deal with propellant re-settling for the RTLS burn.

> Russia’s space program “is a story of poor execution, low funding and poor quality control,” says Maxime Puteaux, an analyst with Euroconsult.

> There’s almost no private space activity in Russia. A pair of Russian companies, SR Space and T1 IT Holding, intend to launch a suborbital rocket by yearend, though they won’t put a spacecraft into orbit before 2025. But Oleg Mansurov, founder of SR Space, is betting that Russia’s increasing isolation will create opportunities for companies like his. Before the invasion almost all satellite data for civilian use in Russia came from foreign companies, he says. With those suppliers shutting down their service, Russia will need its own satellite operators. “We are like a litmus test of what is happening now with private space in Russia,” he says.

> India will now work closely with NASA to send an Indian astronaut to the ISS next year. “The perception in India is that Russia is a technology power that’s on the wane,” says Konark Bhandari, a fellow at Carnegie India, an affiliate of the Carnegie Endowment for International Peace.

>>15589471
https://twitter.com/sdamico/status/1684065706407792640

>In theory, it is possible for a magnetic sail to launch directly from the surface of a planet near one of its magnetic poles, repelling itself from the planet's magnetic field. However, this requires the magnetic sail to be maintained in its "unstable" orientation. A launch from Earth required superconductors with 80 times the current density of the best known high-temperature superconductors as of 1991.
Rocketcucks are through once we get this new superconductor improved

How close to room temperature do room temperature superconductors need to be? Would they settle for superconducts below 5 degrees c? It’s not like you can make cross country power lines with it if it works below 28c, so maybe a little chilly is fine?

>>15589495
You're a fucking retard.

>>15587989
so basically they have the same applications as magnets?

If they met, what would they talk about?

>>15589557
Even one that worked well at dry ice temperatures would be revolutionary. The one in the news can supposedly get hotter than boiling water

>>15589557
Room temperature is 20C, but I think this was tested up to something like 400K, so 127C
but the paper was pretty hastily done
they also patented something 8 months ago

>>15589570
Yes, but it has several problems that could preclude it from being truly useful. If you read the paper in full, it's not all sunshine and rainbows. Now, could they develop this into something capable of the applications that scientists have bandied about for room temperature engineers? Maybe, but I unironically wouldn't expect to see any improvements inside of five years, if at all.

>>15589572
yeah, even if this turns out to be true, you would still have to be able to manufacture it at scale at good enough quality (an example of a material that has good properties but can't be mass manufactured is carbon nanotubes for instance)
but in this case the manufacturing process seems very simple and the elements are very abundant, its just lead, copper, phosphate and oxygen

>For the typical floating superconductor demonstration you heat the superconductor above its critical temperature, place it on a spacer layer above the magnet, then cool it down to below Tc such that it traps flux inside. It’s then pinned in position above the magnet, such that you can even turn the whole thing upside down and it should be strong enough to overcome gravity. They don't show any of this, I would guess because it's not superconducting and instead just a diamagnet.

I know. That's exactly why I'm cautiously optimistic.

theoretically wouldn't nearly lossless power transmission lines allow for centralization of power plants? Like, you could make one giant super efficient nuclear plant to run all of the cities in the US assuming the grid itself wouldn't be impossibly expensive

>>15589954
>suberfondugdivity :d :d :d

>>15589981
I guess you could yes. Although currently transmission losses aren't that high. Just having more cheap power available would improve the grid

>>15589954
/sfg/ - soi face gawking

>>15589981
also would allow for one region to produce a lot of power (like solar) and then just sell it anywhere
you could make a megagrid that encompasses the world
of course building and maintaining the transmission lines would have an associated cost which might make a megagrid impractical just by itself

I'm condoocting!!!!!

>>15589981
You could do that though it would be pretty dumb to do. One amusing thing would be that high power transmission lines would likely be DC so Edison will have finally beaten Tesla

>>15589970
Not ones with great energy density. Power density could be ridiculous.

>>15590001
why do superconductors have to be DC?

>>15590006

Armor plating is the obvious answer. Normally this would be impractically heavy, but you don't actually need to armor up the whole ship, just the parts that are in the direction your expecting or planning to have the laser fire incoming from. If you're working in a reasonably low-tech setting you could have Orion drive ships that turn their tail plates to face the enemy as soon as they enter combat. Your ship wouldn't be able to maneuver while its fighting, but that's not really a problem since strong laser weapons make combat maneuvers impractical anyway.

Interesting news

>SpaceX has begun using a new launch control center at the company's Hangar X facility at KSC for Starlink missions.

I suspect they need a localized launch control to reduce the latency between launch/control. Maybe an eventual moving of headquarters is in the pipeline

Nobody is paying attention to the most space-relevant part of the superconductor story: one of the steps requires baking in vacuum. We finally have our justification for industrializing space.

>>15590268
>I suspect they need a localized launch control to reduce the latency between launch/control.
It's not just network latency, it's the timezones. Trying to organize east coast launches from the west coast jetlags your whole launch management team, even if your fairing release isn't installed backwards and your upper stage engine doesn't have a kerosene leak. With their Starlink launch cadence, SpaceX has probably been getting complaints about sleep cycles from their Hawthorne office.

>>15590311
USA really needs to switch to a single time zone.

>>15590311
Yeah sleep cycle issues is probably a thing due to high paced workflow. Redundancy allows SpaceX more flexibility in launch too, because they will likely also need multiple launch controls for future Starship missions.

>>15590323
That would never fly. You really think Maine and Guam should be on the same time? People would just start using locally calibrated time instead of timezones again.

>>15587989
wait, can't this technology solve the tile problem? you can make a big ass electric field to shield from the plasma with superconducter magnets that don't need the exotic overweight cooling system

will starliner ever fly people? I don't think so.

>>15590288
Is it really easier and cheaper to ship all the materials up and back from space when you could just use a vacuum chamber?
Anyway we'll soon have an even better justification for space industry when varda gets their meth (or whatever they're making up there) back.

>>15590340
>Is it really easier and cheaper to ship all the materials up and back from space when you could just use a vacuum chamber?
They need to be single-cast in vacuum. On the scale of kilometers for casting long distance transmission wires going to space is in fact easier.

India could. They're planning to build a 20 ton single-module station so Gaganyaan will have a destination once its operational. The only problem with that is that India doesn't have a rocket that could lift a 20 ton payload. Teaming up with Russia to launch it on an Angara 5 has been a possibility for a while now. Making it a part of a larger station instead of a standalone project could make it an easier build.

China's not going to be interested in a collaboration and South Africa isn't going to have the economy to contribute anything beyond the occasional token astronaut anytime soon. Brazil is probably in the "astronauts and experiments only" camp, but they're one to keep an eye on.

Does this have any way to help us make/store anti-matter?

>>15590632
yes, but I doubt its going to be enough to actually make a difference
you could make cheaper/better particle colliders with better magnets, LHC uses superconductors for instance but the required cooling makes it more expensive to run and build
better magnets also allows you to store antimatter in magnetic bottles better, but the amounts that are made in particle colliders are so miniscule I doubt its going to be a thing

JUNO will make it's closest flyby of Io on July 30th

Which is notably not inside the magnetospheres of any of the gas giants.

The future of spaceflight is Clear.

So true!

LET'S FUCKING GO!
No more pussyfooting!

This better be bait

NOOOO NO ANOTHER BORING STREAM OF TWO ROCKET BOOSTERS LANDING SIDE TO SIDE

>>15591553
SpaceX will fail

>>15591477
should we get a launch thread? Viasat 3 was fully expended so no hype-as-shit double landing, but this one will have it and it's also back-to-back after a starlink like 1hr earlier

An advanced colony utilizing ships that require a large amount of electricity would likely start beaming power in any case. You're looking at about 50-100 metric tons for 1 MW fission reactor which is a serious handicap when it comes to low thrust acceleration even with the QI meme drive and with that many reactors required most outer planet colonization would remain prohibitively expensive.

Even without laser electric or mag sails, a purely nuclear electric spacecraft is questionable proposal when you could have a solar power sail electric tug stage do most of the legwork before returning to Earth since it's only near Saturn where nuclear gains a better specific power. Alternatively the panels can be jettisoned and the reactor would be mainly for the capture burn.

>>15591572
Nah, its fine. Threads should be saved for super interesting launches. Only Starship comes to mind.

>>15591587
probe launches are interesting you retards

>>15591593
Why are they interesting, you stupid fuck. They're not interesting at all. Unless if they're being launched by Europe, where there's a chance of failure.
