spaceflight has been boring this week

first for boeing BTFO

>>12007824
>Indian rocket
a sad reminder that the entire Indian space industry has been shut down since March due to COVID. They had a dozen launches scheduled this year, but may end up with none!

I want to build an orbital ring system around the world with an integrated mass transit system so that the Kárman Line can be a train route.

>>12007889
They are working with a skeleton crew though so there is a possibility

>>12007895
>>12007889

It seems that it is the same for Roscosmos, they wanted ~40 launches this year but thus far, less then 10.

I hope it doesnt interfere with the development of the Gaganyaan and Orel spacecraft though.

>>12007890
Why?

>>12007953
Because it would be funny.

Maybe a dumb question but would a space elevator have any sort of cooling or heating effect on the Earth? What if you put a big honkin radiator on the counterweight and ran a massive cooling loop and and down the tether?

>>12007992
The better question is what useful work you could extract out of that heat gradient instead of just radiating it out into space.

>>12007992
I think there have been proposals to do something similar with beamed microwaves and laser systems.

>>12007824
Reminder that while hydrogen and methane are both non-toxic gasses apart from risk of asphyxiation due to displacement of oxygen, methane is nonetheless the cleaner propellant, because purified methane is produced via condensation processes working with mixed natural gasses, whereas hydrogen is produced as a by product of the recombination of shorter chain hydrocarbons into longer chain hydrocarbons, in a process that both consumes hydrocarbon fuels and produces more fuels that go on to be burned elsewhere. Therefore, every single molecule of hydrogen produced represents the creation and release of dozens or perhaps hundreds of CO2 molecules, whereas every molecule of methane produced represents only a couple molecules of CO2 released.

If once considers a future scenario where chemical fuels are being produced via clean energy, such as nuclear fission, then even in that case methane is the better propellant for the environment, because while hydrogen fuel production via water electrolysis is a totally carbon-neutral process, the production of methane from carbon dioxide actually removes carbon from the atmosphere. When the fuels are burned later, the methalox rocket produces water and CO2, but not all of the captured carbon goes into the atmosphere. Every time a Starship leaves Earth orbit for interplanetary space, it always carries away at least a few dozen tons of methane, which represents a net reduction of CO2 in Earth's atmosphere of a mass about 2.75 times greater (because CO2 weighs 44 g/mol and methane weighs 16 g/mol but both have the same number of carbon atoms per mol).

The truth is out; hydrolox rockets are actually far more polluting than methalox rockets today, and in the future will do nothing to assist with carbon sequestration projects, meaning hydrolox rockets are effectively a symbol of climate denialism and scientific ignorance. Defund all hydrolox vehicles now and stop raping the environment, allow humanity to progress into space.

>>12007992
>ran a massive cooling loop and and down the tether
>imagine more than 30,000 km of head pushing on the seals at the bottom of that loop
bruh

I found out why Starship keeps popping in ludicrous fireballs.

With the new Axiom and Russian modules, can we expect the ISS to eventually have a permanent crew of more than 7?

>>12008171
You actually think the Russian are going to get that module off the ground anytime soon?

>>12008171
No, because the Axiom and Russian modules are designed to calve off as separate stations.

Out of curiosity: has any other large space agency (I’m thinking most likely ESA, maybe Roscosmos) launched a mission on F9 without ANY help from NASA?

I’m asking because I think it would be funny for ESA to do something like their CSTS (proposed Orion competitor w/ russia that ended up falling through) all by themselves after getting cold shouldered from orion

That Boeing is quick to make improvements then threatened with losing a contract.

>>12008490

Probably mechanically impossible to begin with, a large portion of the liquid in that loop will still be in a full g, and I think that essentially no material could be both strong and simultaneously light enough to both deal with the pressure and still be attached to a space elevator.
Climate manipulation, if such folly is desired, can be much more easily accomplished with swarms of semi-opaque panels or sails orbiting the Earth at it's equators. Some may simply absorb a portion of UV and other radiations, others can be made reflective to visible light, still others can be used as mirrors to direct light to desired portions of the planet or to bounce extra light into space, raising the planet's overall albedo.
I don't think it would be very smart to meddle with the modern climate optimum's growth, climate cultist hubris never made much sense to me.

Anon, the apollo program kicked off by roasting 3 people to death due to an astonishing level of incompetence and horrible design. It came veeeery lose to being outright cancelled. Ego was 100% a major weakness of the early space program.

>>12008588
Anon,I know that in modern times that people are hypersensative about race,but when the Apollo program was a thing,black people were genuinely 100% oppressed by wide sections of society. Educational opportunities were not handed out fairly. The tweet is 100% objectively correct. Would you like detailed stats from the time about educational funding,voter suppression, discrimination in higher ed?

How is the tweet wrong or inaccurate?

>>12008580
Yet, without that level of drive and ego I would guarantee that it could never have happened at all. Humans die during ambitious projects, if the project is voluntary than they die by choice, taking a risk for the furtherance of both themselves and all of their fellow human beings.
Is burning to death in an experiemental vehicle that will one day soon take human beings to another planet a horrific way to die? Yes. Is it also one of the most productive and noble ways to die? Also yes. It's the same reason people fed up with the politics of the British Empire decided to jump aboard ships with no heating, barely any ventillation, possibly ridden with disease, and cross the ocean risking drowning, starvation, and a hundred other horrific deaths for a common goal.

Yes, the reason why the space race was between two white countries was only because blacks were being kept down from Jim Crow and colonialism right? If Jamal was only given affirmative action a little bit sooner then Wakanda would have been fully realized, flying pyramids and all. Spearchuckers living in their mudhuts who hadn't invented the wheel or built any two story buildings didn't deserve to be represented by the most advanced engineering project of its time. Only one group could have done that, and the inclusion of objectively less-capable groups would have only hindered their progress. Again, kys

You’re right. We’d be better off if we wiped them out or evicted them back to their disgusting continent. The genetic distance between Europeans and Africans is almost exactly the same as the genetic distance between North American Grey wolves and coyotes

>>12008611
White woman detected. Black prosperity in the US was at its peak when segregation was in full swing. Harlem Renaissance, Detroit and the motor city boom, etc. nosy white people like you went and undermined what little black power structures that existed in favor of integration and subsequent codependency on whites just so you can feel better about yourself.

>>12008473
Looks like a black arrow.

>>12008671
You realize that blacks were better off when they were "oppressed" right? Less illegitimate children, less crime, less drug use. More segregation = less racial tension = better for everyone. Look at Africa, every country where Europeans had a major presence has had their quality of life increased. In surveys older blacks describe their degree of perceived discrimination to be lower than that of young blacks.

How would that work? You'd need to suspend or cancel the constitution and then make the government powerful enough to round up and kill or deport millions of citizens. How would that ever happen? Every poll or analysis shows most Americans, including whites,reject any such violent solution.

Genetically engineer niggers into white people.

>>12008711
Reinstitute segregation but frame it as blacks segregating from whites instead of the other way around. Black people are just not culturally stable enough to be interacting and participating in white society on equal footing, not yet. You can’t take a people who were in the Stone Age only a couple hundred years ago, enslave them, catapult them through the industrial revolution, and expect them to be able to find their legs in only a few generations. Integration was done ham fistedly for the sole purpose of alleviating white guilt to nothing but black folks detriment.

I still cannot fanthom the amount of incompentency on Boeing's behalf. Not even 1 (one) systems intergration check to see if everything would work the way it was meant to work. Mind you that this was THE mission for Boeing to show that it could be up for the task and BTFO any shred of doubt but it turned out to be the shitshow bording on the clownesque.

I still have fits of laughter when I think about that mission controll graphic seeing the various thrusters of the Starliner firing in a state of spastic, epileptic ADHD seizures.

Well, that and the Boeing 737 MAX horrorshow HAS to have had a signifcant impact on recruiting of any kind, not just internships.

The sad state of that company came about when Boeing acquired/took over McDonnell Douglas and slowly but surely the destructive, business oriented approach took over product oriented philosophy. In other words, money making became more important than delivering a good product.

It's a bit like insider trading except you're doing it on a closed contract bid.
For a closed contract bid, all potential contracters are asked to deliver their proposals for the competition, none of the other contractors know the details of one anothers bids or specs or any of that shit. Nobody knows the weaknesses or strengths or how they compare to one another or exactly what they will see as strengths and weaknesses compared to one another. All they know is the specs NASA wants for the mission and shit like a timeline they expect it done and like a rough budget guideline they expect or whatever.

This guy told Boeing that their shit was too fucking weak compared to the competition and to unfuck it PRIOR to the contest.

Any climate scientists here? What would the climate/ weather of a terraformed or partially terraformed Mars look like? Based on all of the land in the south and the ocean in the North, it looks like it will be a monsoon climate. Can anyone predict what the winds and currents would look like? Would the south be very arid no matter what? How would seasons be different with such a longer year? Could Mars ever get warm enough with enough CFC or sulfur hexafluoride. Is it possible to get Mars to Earth temperatures and pressures with these chemicals starting a chain reaction to release the permafrost CO2? What kind of species could we use to help? Types of algae, moss, high alpine trees? Is genetic engineering a must? Where would the cities end up being built?

Neat.

>>12009296
They'll have to be further from population centers as rockets get larger and louder. I think as long as stainless becomes more common sea launches will also become more common, likely from custom launch platforms based on oil rig structures. As rockets become increasingly cheap and reusable you might see something more like an airport, but with landing disks instead of runways, and obviously with the tower and payload loading areas much further from the pads, without any big windows that could be blown out by launch noise.

One can use 8.8 km/s to go very far away from the sun, then use a negligible Δv to bring the angular momentum to zero, and then fall into the sun. This can be considered a sequence of two Hohmann transfers, one up and one down.

>>12010104
Not him, but a question :
You still need delta V to join the cycler orbit and delta V to get out of the cycler.
So what exactly is the point of the cycler?
Is it to provide radiation shielding which can be reused for many missions?

>>12010161
the point is mostly just to have a big heavy piece of shit that you can live in for the trip without having to launch a big heavy piece of shit every time you want go

>>12010163
Makes sense. Now how big are we taking about here? 1000t?

>>12010163
What's the delta v required to get on the cycler from earth and delta v to leave the cycler and land on Mars?
Why aren't we building this instead of that lunar station?
Also where can i read more about this?

>>12010174
it's basically the same delta v to get on the cycler to go to mars directly, but you only have to accelerate a tin can full of astronauts to catch up to the cycler instead of some heavy piece of shit with actual living area and habitats for the trip

>>12010625
In my opinion, a lot of people knew about Boing and NASA having buddies in the background doing shady things like this. It has been going on for decades.
Now that SpaceX is a powerhouse, and BO might be joining the party later, the corruption could be cut away without fear of Boing threatening to stop production on huge projects.

Anon, you do have the Bluedog design bureau mod installed right?

>>12010805
Also the difference between ULA projects (Vulcan-Centaur) and pure Boing! projects (Shartliner) is pretty damning about where the fault lies. If ULA gets their engine reuse system working for Vulcan they'll be almost on par with F9.

aleays remember that Elon himself (who is known for his Elon time) said that the 2024 deadline was ambitious. that was also before they ran into problems after problems during testing. remember that at that time the first orbital flight was expected somewhere at the end of 2019.
so no there won't be a crewed landing in 2024 and most probably also not it 2027

>>12011007

>>12011031
I'm not currently running the game, so you'll have to use your imagination for the most part. There is a central tower inside with 2 greenhouses, 2 MK2 habitats, and a fusion generator, which is one reason why my mothership has all those radiators.

>Senator Shelby called NASA and said if he hears one more word about propellant depots he’s going to cancel the Space Technology program.
I thought this was just a /sfg/ meme, what is this guys problem?

>>12011143
They don't make propellant depots in Alabama.

>>12011143
He is but a shell for a loathsome demon hailing from the damned inferno itself.

>>12011103
Since KSP doesn't actually require antennae to be oriented properly, I could effectively internalize communications.

>>12011147
I didn't know that, never thought about it I guess, makes sense to me. I often like having the antennas on a boom though, just because I like the look of it.

>>12011143
D*p*ts allow for smaller rockets (ex: Atlas V, or Falcon 9) to carry larger BEO payloads like what the SLS can do, but better in every way apart from needing to loiter in LEO for a while. This means that sly members of Congress who don't benefit from SLS might use this as justification to try to cancel the program. Since Shelby has a vested interest in keeping jobs in Alabama, and that SLS provides a huge amount of highly skilled jobs, he got ULA to back down on d*p*ts and had the concept buried.

It's not some irrational hatred, he has a very solid (albeit filthy) reason why he doesn't want d*p*ts

>>12011155
If SLS were actually flying it wouldn't even be a bad reason. He could just restrict depots to LH2 based to push payloads towards SLS and nuclear upper stages. The continued failure of orangetankbad to make orbit is the only weakness in his scheme.

>>12011182
>If SLS were actually flying it wouldn't even be a bad reason.
IMO if it were flying by 2018, then there wouldn't be nearly as much hate for it. Sure, it would get criticized alot, but at least it'll be contributing to space flight.

>>12011194
If they got Block 2 working it would actually be an interesting rocket... but I suspecy they never will.

with a 3.5 ton payload (almost 6x the mass of parker solar probe), yes, assuming starship can store cryogenic methalox for long enough for the second burn

So what's next for NASA after filename related?

Are they just going to charter some of Musk's starships or are they actually gonna get their shit together and draw up a clean sheet reusable replacement for the Shuttle?

>>12011226

>>12011306

>>12011305
>or are they actually gonna get their shit together and draw up a clean sheet reusable replacement for the Shuttle?
The chances of NASA ever building a major spacecraft like that ever again are slim to none

>>12011305
They're gonna burn more money on SLS to justify the money they burned on it in the first place.
You have much to learn about sunk cost, young one.

>>12011305
SLS gets canned and replaced with the American Launch System (ALS), which promises to be much faster and cheaper than SLS by reusing Shuttle components instead of doing what SLS did by trying to incorporate new technologies.

>>12011305
Un-ironically NASA should stop building their own rockets and focus exclusively on designing probes, rovers, and habitats, and working with companies to train large reserves of astronauts. Companies should be awarded competition based payment-on-delivery contracts for launchers, habs, suits, capsules, ships, etc.
A real celebration of modern American rocketry will be the moment when American free enterprise takes over a project started at the government level.

>>12011143
It would reduce the need for SLS, thus costing him lot of jobs in his state. On top of that, if depots can be used, then less powerful rockets, aka less costing rockets would be able to launch more powerful stuff. This reduces the need for future enormous projects for Alabama.

>>12011318
This guy's congressional district is gonna get funding.

>>12011305
They'll keep paying for Blue/ULA/Boeing because general public doesn't give a fuck about space. All they hear is "oh more more for space"

>>12011308
This is first digital image of person recorded.

>>12011381
>You know that SpaceX (and all US-based companies) is just a puppet of the US government, right?
Considering how much SpaceX fought against the government to get contracts, I doubt this is the case.

>>12011144
They could, though. ULA definitely has spare capacity in their facility at Decatur, and Huntsville has more than enough engineering talent to put together a design team from local sources.

>>12011468
That's beside the point. Those are things that can be reused. Those are not good for pork barrel jobs.
Shelby is a denizen of the deepest part of the pork barrel. He has grown fat and strong on that. He will die content down in that barrel, stuffing his face with its spoils.

>>12011319
On top of the probes and the astronaut training, NASA should work like NOAA or the Woods Hole Oceanographic Institute where they have a small fleet of manned modular reusable spacecraft based on commercial designs that get reconfigured on the fly for specific missions.

Something like a NASA-owned Starship that's set up as a spartan space laboratory where one year it goes to the moon with one set of scientific payloads and instruments for a landing and a 3-month geological survey, and the next year it loads up with a completely different set of payloads and instruments and flies an intercept mission to a near-earth asteroid, and a few months after that it gets its payloads and instruments swapped out again and flies back to the moon for a 2-month stay in low polar orbit using powerful ground-penetrating radar on some joint mapping mission tied to a bunch of folks at Caltech and MIT's postdocs, and then on to the next mission, etc etc etc.
