In wake of eclipse, NOAA prepares for enhanced solar observations; NASA considering budget cuts for Hubble and Chandra space telescopes
----
https://spacenews.com/in-wake-of-eclipse-noaa-prepares-for-enhanced-solar-observations/
> SAN FRANCISCO – As the annular solar eclipse drew widespread public attention, National Oceanic and Atmospheric Administration leaders gathered at the Albuquerque International Balloon Fiesta were considering their own solar observations.
> Solar activity affects satellites and terrestrial infrastructure like the power grid.
> “We’re evolving technology at an extraordinary pace,” Murtagh said. “When we introduce new systems, new technologies, new processes, we often introduce new vulnerabilities to space weather that we don’t fully understand until unfortunate things happen” like the loss of 40 SpaceX Starlink satellites in February 2022 after “a relatively minor geomagnetic storm.”

https://spacenews.com/nasa-considering-budget-cuts-for-hubble-and-chandra-space-telescopes/
> WASHINGTON — NASA is considering cutting the budget of two of its biggest space telescopes as it faces broader spending reductions for its astrophysics programs.
> In an Oct. 13 presentation to the National Academies’ Committee on Astronomy and Astrophysics, Mark Clampin, director of NASA’s astrophysics division, said he was studying unspecified cuts in the operating budgets of the Chandra X-Ray Observatory and Hubble Space Telescope to preserve funding for other priorities in the division.
> “We’re working with the expectation that FY24 budgets stay at the ’23 levels,” he said. “That means that we have decided to reduce the budget for missions in extended operations, and that is Chandra and Hubble.”

I hate space.

>>15804951

>>15804950
I think they need to stop playing games with their budgets and come out with hard cuts across every division

It turns out this isn't really Psyche's fault but Artemis, and Artemis is going to eat the budget alive

why was the RS25 so hard and expensive to refurbish and why will raptor be different? Seems to me like performance scales with wear on the engine and difficulty to refurb

Since we're posting books, found this exchange in a library copy of Rocket Propulsion Elements

>>15805386
Yes, but RS25 running on hydrogen was a more important factor.

Blood still reaches the legs and penis in free fall, otherwise zero g would fucking kill you.
Erections are not influenced by blood pressure, they are caused by constriction of the blood vessels that exit the benis, causing blood to be retained in the spongy tissue, which therefore increases the size of the peneous and makes it rigid.

> The Culture reached this phase at around the same time as it began to inhabit space. Its AIs cooperate with the humans of the civilisation; at first the struggle is simply to survive and thrive in space; later - when the technology required to do so has become mundane - the task becomes less physical, more metaphysical, and the aims of civilisation moral rather than material.
> Briefly, nothing and nobody in the Culture is exploited. It is essentially an automated civilisation in its manufacturing processes, with human labour restricted to something indistinguishable from play, or a hobby.

> The attraction of Orbitals is their matter efficiency. For one planet the size of Earth (population 6 billion at the moment; mass 6x1024 kg), it would be possible, using the same amount of matter, to build 1,500 full orbitals, each one boasting a surface area twenty times that of Earth and eventually holding a maximum population of perhaps 50 billion people (the Culture would regard Earth at present as over-crowded by a factor of about two, though it would consider the land-to-water ratio about right). Not, of course, that the Culture would do anything as delinquent as actually deconstructing a planet to make Orbitals; simply removing the sort of wandering debris (for example comets and asteroids) which the average solar system comes equipped with and which would threaten such an artificial world's integrity through collision almost always in itself provides sufficient material for the construction of at least one full Orbital (a trade-off whose conservatory elegance is almost blissfully appealing to the average Mind), while interstellar matter in the form of dust clouds, brown dwarfs and the like provides more distant mining sites from which the amount of mass required for several complete Orbitals may be removed with negligible effect.

It's interesting to read personal accounts of life at Oak Ridge during WWII. Most people found the intentional managed community to be a great place to live, though the necessary war secrecy did make visiting relatives and other beyond the base difficult. The top talent it was built to foster was able to be very productive because all the external garbage that society usually forces everyone to deal with was kept away. Beyond just it being an intellectual nirvana, the social aspects were greatly appreciated. You could find others with similar interests that appeal to the highly intelligent and not have to worry about those with other agendas disrupting the community.
The "dark side" was the service workers, who initially found life there boring and unfulfilling since the community wasn't designed for them but needed them. Black men in particular had a high level of turnover, which was solved by the management of Oak Ridge getting rid of their then high tech street sweeping machines and replacing them with black women who would sweep the streets manually. Adding black women to the community satisfied the social needs of the black men there in support roles.
After the war many tech companies tried to replicate the fruitful environment of Oak Ridge by building research parks away from the distractions of large cities. Initially these worked well, though not always as well as Oak Ridge had. But over time it became more and more difficult to control the makeup of these communities, which often attracted people of limited ability seeking a better situation for themselves.
It makes one wonder what could result if intentional communities weren't mostly illegal. Universities were often located in rural areas not just because of various land grant considerations but also so they could be isolated intellectual communities. They have of course been perverted into something bordering on the grotesque, wearing the skinsuit of what academia once was able to be.

It was the wrong engine for the wrong purpose and now it's being used in the worst possible way compared to its original designs that predated the final shittle mission profile. It's comical, in its own right. It shouldn't be used as a comparison for anything.

>>15805386
That meme about how they forgot how to make the F-1 applies equally to RS-25. Rocketdyne has almost negative institutional knowledge of engines it used to build.

If you read https://oig.nasa.gov/docs/IG-24-001.pdf he points out how insanely optimistic they are being about how much it will cost in the future. They were putting out papers like the one in this post estimating outrageous cost savings IN A GOVERNMENT PROGRAM (contractors have not willingly lowered their prices since WWII). The only reason Artemis is even possible is because they're using SSMEs, if they did not have the SSMEs the program would have been DOA as soon as Constellation got cancelled

>>15805735
larger mass flow for same combustion energy = lower temperature

>>15805771
Doesn't that resuce specific impulse? Thrust power/energy is equal to mass flow time exhaust velocity divided by two, so increasing mass flow while the energy in constant should result in lower exhaust velocity and specific impulse.

Fingers crossed it works this time.

>>15806032
the raptor failure rate has been a pretty consistent 25% in the test flights over the years.

>>15806060
The theory we saw passed around after the last test fire is that they're having issues keeping pressure constant during startup and a few basically get starved and flame out.

All these engines are tested and working at the factory.

>>15806060
Something I think we're going to see a lot less of on IFT-2 if SpaceX's engine bay fire mitigation measures are any good. The days of Anons saying "25% failure in flight" and being taken even remotely seriously are probably numbered.

Related notices have been posted for the coming week, marking the imminent return to a full stack for the next Starship to launch as soon as November, pending regulatory approval.

SpaceX Space Station

https://chrisprophet.substack.com/p/spacex-space-station
>In 2021 SpaceX made a bid for a Commercial LEO Destinations (CLD) contract, a program set up by NASA to support private space station development. Unfortunately their bid wasn’t accepted but they didn’t give up, and have since landed a Space Act Agreement (SAA) to collaborate with NASA on a Starship based space station.
> According to Mars Society founder Robert Zubrin, ”orbital research labs” are the next big space app, after satellite communications. All manner of new products can be researched and manufactured in microgravity, such as innovative drugs, virtually lossless fiber cables, even complete human organs ready for transplant. Realistically we have barely begun to tap the possibilities, with many more applications likely to emerge when a commercial microgravity facility becomes available.
> Due to a combination of factors i.e: NASA’s urgent demand for a commercial space station, the inability to fund this project by primary contractors, and salience of Starship development, it seems increasingly likely SpaceX will diversify into the space station business. Arguably NASA has already begun to move in this direction following their Space Act Agreement to build a Starship Station supported by Dragon transport and Starlink communications. Currently the company has more pressing priorities for Starship development, e.g. producing a propellant tanker, orbital propellant depot and Human Landing System version for the Artemis program, not to mention their own cargo variant for deploying Starlink satellites.

>>15806074
> Realistically they should have time to build a space station variant in the 2025-30 timeframe, which would allow NASA to maintain space station research, at considerable cost saving compared to the ISS. However, this would not be pure altruism on SpaceX’s part, no doubt this arrangement could be quite beneficial to the company. The ability to supply suitable space transport to their own station at relatively short notice will become increasingly lucrative due to the demand spike as the 2030 deadline approaches. Then a profitable space station could open the flood gates for a sustainable space economy.

>>15806096
If I could somehow throw away my principles I imagine that would be incredibly comfy.

>>15806082
If I put my Noticer hat on, I can make some pretty wildly irresponsible speculations about this
Much like I think the refugee investigation is about Ukranian rocket scientists, there is probably something international interfering in the supply chains for these contractors. I'm thinking pretty specifically about that supplier that needed to redo some part on Artemis and connecting the dots to China banning exports of some materials. The contractors may have had every expectation that they could have made the bids, but as soon as they checked in with their suppliers to place orders the prices went up. Way up. Or simply became unavailable for any price.

>>15806101
As someone who has smelled a whiff of oldspace, its an incredibly lucrative offer. Shitpost from home and raking it in, compared to sweating it out in south Texas for more hours and less pay. I don't blame them.

>>15806234
you have no clue what you're talking about. raptor has almost no 3D printed parts at all, and musk is constantly looking for ways to decrease that even further. the combustion/thrust chamber are explosively formed and milled, and the engine bells are machined as well. raptors are designed to be mass manufacturable, the exact one thing that 3d printers are worse at than literally everything else that they also suck at. proonting is cope for engineers that can't design good parts

I would strongly suspect that the HLS Starship would essentially be the next-generation space station. SpaceX would have to use either a reusable Starship or a disposable Cargo variant to orbit, where it can put up a 7m by 7m by 15m integrated truss/cargo/dock to which these HLS Starships can connect to and which has inbuilt station keeping thrusters and to which fuel can be transferred between ships or from ships into the station. Then Starships and Dragon spacecraft can come and dock to it and this truss would over time expand/extend to allow for more Starships to dock to it.

Why isn't SpaceX already sending ISRU plants to Mars on Falcon Heavy?

>>15806636
They have more important things to focus on, like getting Starship working. That said there's a NASA Mars mission slated for a Falcon launch in the not too distant future.

I wonder if MSR is budgeted for a Falcon Heavy? If so is SpaceX actually to blame for making it cheap enough they thought it was doable?

>>15805816
I am wondering the same thing. When are you sciencegoys finally leaving ball earth? What is taking so long

>>15806371
BO has taken so long that at this point what is even the market for new Glenn? they get 6 launches per year max, probably less, which makes cost per launch likely higher than a smaller non reusable rocket of the same payload. Starship faces a similar launch frequency issue but at least SpaceX is already dominant

>>15805901
I prefer Spationaut anyway.

I'm a SpaceX super fan and have been since when they were splashing falcon 9's down in water without legs whilst testing the propulsive landing. I have serious worries about SpaceXes future. Starlink is a humungous money sink which does not cover its own cost and will not for at least half a decade if ever, and Starship is equally a money sink, and Elon has to cover half the development cost of the lunar HLS himself, some of that he scammed the Japanese guy for, but the rest needs to come out of funding rounds. He has said it himself many times throughout the years that SpaceX is desperate for money, and at the moment it can secure money just because its the largest launch provider on the planet, but that wont be the case forever. It's clear to me that the first Starship launch happened as a publicity stunt to secure more funding. Starship will probably be developed to an orbital state, but we have no idea the launch cadence necessary to make it cheaper than an F9, and F9 already launches multiple times more than the whole world launch market. Starship requires tanker refuelling, so even assuming 1 starship flight is 1/8th the price of an SLS, the total price to reach the surface of the moon with starship would still be more expensive.

>>15806810
BO can launch Kuiper sats just like Starship can keep launching Starlinks
the total starlink constellation size is going to be 30k or 42k, which is 6k or 8.4k a year respectively with 5 year lifetime, 400 sats pre launch is 16 or 21 starlink launches
if they make them bigger, which they might have already done (only 22 v2 minis instead of the 60 originally on falcon 9), then that number might go up
so perhaps starlink launches aren't enough to justify Starship if you just look at the launches but creating starlinks larger constellation would probably not be feasible without Starship and the whole project will still probably be profitable overall after you amortize starship dev costs + starlink dev costs + launch costs of starlink + costs of the starlink satellites

>>15806819
> Starlink is a humungous money sink which does not cover its own cost
incorrect
> Elon has to cover half the development cost of the lunar HLS himself
incorrect, its 3Bil free money for NASA for stuff they would have to develop anyway
> He has said it himself many times throughout the years that SpaceX is desperate for money,
yes like 15 years ago when the company was in startup mode
> Starship requires tanker refuelling, so even assuming 1 starship flight is 1/8th the price of an SLS, the total price to reach the surface of the moon with starship would still be more expensive.
do you have any fucking idea how expensive the SLS launches are?

>>15806819
>“This year, Starlink will make money. We actually had a cash flow positive quarter last year,” Shotwell said.

>>15806820
People who are too rural to have ground internet but rich enough to afford satelite internet are not very common, Kuiper makes a bit more sense because they will give the internet out for very cheap and then make their money back by getting people to use amazon services

>>15806834
common enough for Starlink to have 2Mil customers already and they keep signing contracts with airliners and shipping companies

>>15806833
Listen... You and I both know that Shotwell is a hoe and Elons bitch. She will do and say anything he makes her do and say. And he is notoriously optimistic about his own abilites and even reality.
>>15806830
Show me proof starlink is a net cash generator.
Elon was going to develop starship anyway, thats true. But its still largely on his own diem and money doesnt grow on trees.
Cost of development plus launch will be very far apart because NASA has so much bloat, but cost per launch on its own will not be too dissimilar. Most of the price of a launch is ground crew.

>>15806834
>People who are too rural to have ground internet but rich enough to afford satelite internet are not very common
In no sense does rural mean poor.
It only takes 10min of driving to go from a place from gigabit fiber to very bad dsl/satellite.

>>15806839
It's a private company and we don't know their internals. How would I show that proof. Show proof that they are running a net loss. But we do know that they raised $750M this January at a valuation of $137B. Normally you don't do that sort of stuff if you can see from the numbers that the company is doomed.

>>15806088
I hope they do but let's let the empirical tests decide. They seem to be more focused on increasing pressure than increasing reliability currently

>>15806856
"Increasing reliability" in this case means closing up and otherwise mitigating the effects of the engine's leaky pumps and joints. "Raptor must be more reliable" isn't wrong, but it lacks insight. Everything SpaceX has changed is designed to improve Raptor reliability on the rocket.

>>15806961

>>15806958
lets talk about those too. Generously raptor has a 10% failure rate which is bad. I didnt feel the need to bring it up because I imagine sapcex can fix that given enough time. Why is bringing up the dire finances a troll move?

>>15806967
I don't think the finances are dire. Considering that F9 is so cheap and reliable and that SpaceX is eating the competition it's hard to believe the finances are dire

>>15806967
They’re literally numero uno in the market. Funding is a non-issue, between gooberment handouts and private funding they can afford to lose money on starship and starlink for 2 decades—if not indefinitely lol

>>15806970
we have no idea how cheap f9 is internally, and the vast majorety of SpaceX launches are not generating a profit because they are Starlink launches.

The fact that smallsat launchers still exists tells you all you need to know. F9 with a reusable booster is still at least not cheaper than a small rocket. SpaceX relies on funding rounds to continue. If they were completely unambitios I have no doubt they would make a profit, but they have an active policy of deep financial overextension to grow the comapny at a rapid pace, which Musk and Shotwell both admit to

>>15806902
that is a pretty shitty plan with no certainty of success
and the larger point is to keep human civilization and consciousness going, not "life"

>>15806977
considering they can outbid everyone it's fair to say that they must be cheaper than competition.

>>15806977
its pointless to argue this with you when you dismiss what people like shotwell say
no point arguing with conspiracy theorists

>>15806894
Brevity is wit of the soul

>>15806984

>but they dont dominante the smallsat market
Nigga… you’re either just trolling, or you have an extra chromosome that’s bringing you down hard right now

>>15806982
and reminder, they were outbidding the competition years before any falcon 9 stages landed

>>15806996
starlink is not part of the smallsat MARKET becuase its made by SpaceX

>>15806977
Musk said that the marginal cost of a launch is $15 million and refurbishment is $1 million in an ideal scenario. That was in 2020 and I think its gotten even cheaper with increased cadence. Its also the reason I think Starship launches can realistically get to at least $5 million in price.

>>15805790
He's talking about the turbomachinery.
The main combustion chamber burns as hot as ever, but consistent MCC cooling is relatively easy, since all the exposed hardware can be made of cooling channels and if you need to you can inject extra fuel along the walls to provide a colder boundary layer.
Inside the turbopumps though, you have hot gasses impinging on spinning turbine blades that cannot easily have any coolant applied at all, so reducing the temperature of the preburner exhaust can result in a vastly more benign turbine environment.
The RS-25 needed almost no nozzle or main combustion chamber work to refly. It was all turbomachinery teardowns and blade inspections, because that hardware had to deal with hot hydrogen rich gas, which loves to murder the shit out of most alloys via embrittlement.
In short, Raptor has proportionally less extreme turbine conditions and can use much better (stronger, more heat resistant) alloys because it isn't limited to what won't be chewed up by hot hydrogen.

> Because it lacks the funding to modernize its most historic launch pad, Russia now instead plans to turn "Gagarin's Start" into a museum.
> The pad is known as Gagarin's Start because it hosted the world's first human spaceflight in 1961, when the Vostok 1 mission carrying Yuri Gagarin blasted into orbit. Between 1961 and 2019, this workhorse pad accommodated a remarkable 520 launches, more than any other site in the world.
> Most recently, during the last two decades, the Soyuz-FG rocket launched cargo and crew missions from Gagarin's Start, which is located on the Kazakhstan steppe near the small city of Baikonur. The final launch from the site took place in September 2019, with the Soyuz MS-15 mission carrying Russian cosmonaut Oleg Skripochka, NASA astronaut Jessica Meir, and United Arab Emirates astronaut Hazza Al Mansouri to the International Space Station.
> In November 2021 the UAE announced it had reached a "trilateral agreement" with Russia and Kazakhstan to modernize Gagarin's Start to promote peaceful space exploration.

Space insurers take cautious approach to satellite servicing,
---
https://spacenews.com/space-insurers-take-cautious-approach-to-satellite-servicing/
> WASHINGTON — Despite satellite malfunctions that are expected to lead to major insurance claims, the space insurance field is taking a cautious approach to servicing technologies that might be able to repair such spacecraft.
> “It’s the worst market we’ve been in in the last 20 years,” he said. “In the last six months there’s been about $1 billion in claims against about $500 million in premiums.”
> Those claims will likely include two malfunctions of recently launched satellites. ViaSat-3 Americas, also known as ViaSat-3 F1, encountered a problem deploying its large antenna that will reduce the available capacity on that broadband satellite by more than 90%. Viasat reported a separate problem with the power subsystem with the Inmarsat-6 F2 satellite in August that raised questions about its ability to operate. A total loss of ViaSat-3 F1 could result in a $420 million insurance claim, while Inmarsat-6 F2 could result in a $350 million claim.
> Quinn spoke at a conference organized by CONFERS, an industry group promoting development of standards and best practices for satellite servicing and related applications. Some in the field have argued that satellite servicing could, in the long term, help reduce insurance claims, with insurers themselves potential customers of those services.
> Getting insurers comfortable with satellite servicing, he said, will be a long-term process.
> As for whether insurers would be customers of satellite servicing, Quinn said it’s possible at some point. “It needs to be available, it needs to be reliable and it also needs to be cost effective,” he said of satellite servicing. “It needs to cost less than the alternative.”

Blue Origin Unveils Multi-Use Platform For Earth Orbit, Beyond

> “This is going to leapfrog all of the other orbital transfer vehicles, tugs and propulsive-ESPA concepts that are out there,” Lars Hoffman, vice president government sales, said in an interview with Aerospace DAILY.
>ESPA is an acronym for Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter.
> For starters, Blue Ring can host and/or deploy 1,100-lb.-class satellites on a dozen generic ESPA and ESPA Grande ports, which are 15-in. and 24-in. in dia., respectively, as well as anchor a 2-ton-class satellite on a top deck.
> A single Blue Ring can carry more than 6,660 lb. of payloads, depending on whether the spacecraft would be flown to single or multiple Earth orbits—including geostationary—and/or to Lagrange points, cislunar space, lunar orbits or even to interstellar space.
> “We have interest in launches in 2024-25,” he added. “I think the realistic first launch of Blue Ring will be 2025. We’re going to let the market dictate how rapidly this grows.”

>>15807201
>some nonsense bullshit
Primitive inuit people colonized the fucking arctic and survived for thousands of years, and you think a Mars settlement inside of cozy habitats with modern technology won't flourish because the air pressure outside is low? Grow up.

>>15807213
>>15807210
>>15807205
there are no humans living in self sustaining cities in antarctica, despite the fact that there is food in the form of penguins and plentiful air and water. Living on Mars by comparison is laughable

>>15807209
SpaceX is even planning to launch another version of the rideshare mission, don't remember the orbit now but might have been for polar orbits or something

how many retards do you think actually buy this stuff off their website

>>15807215
there are no humans living in self sustaining cities in Antarctica because there is not reason to do that
growing food and mining water etc will be much cheaper and more important to do on Mars, so it will be done

>>15807217
whats the story here?

>>15807217
well they are still going to I guess enough for the operation not to stop

>>15807215
Not an argument. There aren't cities in the arctic because noone wants to live there.
People do exist who want to colonize space, therefore it will happen. Any statement to the otherwise is basic denial.

>>15807215
but we easily could if it were considered desirable

>>15807220
Cybertruck drove around with a vacuum raptor last week around starbase, probably for Cybertruck press photos as it is expected to launch soon

>>15807219
>growing food and mining water etc will be much cheaper
how? On antarctica you are sitting on kilomiters of fresh water ice, on Mars I dont even know how you would capture a large amount of water from the desert soil. If you figure it out then you should try terraforming the sahara first.
If you cant grow food in antarctica you sure as hell cant on Mars.

>>15807228
>you should try terraforming the sahara first
would you believe there are self sustaining cities there already?

>>15807222
>>15807224
>we could easily do it!
Russia would like to know. If it was so easy then Russia and Canada would be the two most pwoerful countries on earth due to their land area.

>>15807219
Yup, making oxygen and growing food in high density indoor farms is actually very easy, the reason it isn't done on industrial scale on Earth is because of lack of incentive due to economics, just as you said.

>>15807230
>would you believe there are self sustaining cities there already?
Only a tiny number at Oases, which dont exist on Mars. All the other cities rely on infinite food imports

>>15807228
cheaper than launching them from Earth is what I meant
comparatively, making the mars colony self sustaining from a food and water pespective is cheaper than sending it from earth
doing the same for Antarctica is not cheaper, it is much cheaper to grow the food in areas of the earth that are suitable for it and then send it to Antartica
again retard, its not about that we "can't" grow food on Antarctica, its just that it makes no fucking sense

>>15807228
I'm pretty sure you can't do solar full year round there, and nobody would let you use nuclear. This is part of the reason why seasonal research bases are the only settlement there.

>>15807159
less money for contractors (especially rockwell)
posed a threat of reduction in air force's influence over the program
astronauts especially hated shuttle C for reducing the number of astronauts needed by a lot; easily half of the satellite-deployment STS missions didn't actually need any humans in orbit, but even the astronaut corps was going on about 'bert whert erbert mer jerbs'

But it was mostly that the shittle was a pure jobs program which drove up costs, and every contractor even remotely tangential to aerospace wanted a pjece of that tax-funded goobermint pork pie. shuttle C was the antithesis of that, reducing the number of contractors AND the amount remaining contractors would be paid

>>15807236
And people would let you launch a nuclear reactor on a rocket?

>>15807238
no, but on mars solar year round is at least doable.

https://www.youtube.com/watch?v=MTiM7dVp-wU&ab_channel=Pressure-FedAstronaut

>>15807159
Because 1 Shuttle-C could do the work of 3 or more Orbiters and astronauts ride Orbiters not Shuttle-C's

>>15807228
>desert soil
You really don't know shit about Mars, do you.
3/4th's of the entire planet is permafrost under a thin layer of dry dirt. Water is ubiquitous on Mars.

>>15807231
There's no demand for it.
There IS demand for settlements on Mars.

>>15807242
There are patches of ice. Thats it.

>>15807236
The reason Antarctica isn't settled in any industrial capacity is because there are a million treaties preventing anyone from doimg so.

>uranus has an axial tilt of 97 degrees
wtf why have we never sent a probe to study these ice giants?

>>15807238
NASA plans to, so yeah.
Regardless, Mars has uranium, so even if there was a total ban on launching nuclear fuel, we could still launch every other part of the reactor and supply the fuel in-situ.

>>15807247
Congress stopped caring the second the american public stopped caring. Also the current coons at NASØY keep giving money to worthless missions like Europa Clipper (how many fucking Jupiter missions now, and JUICE already launched), Dragonfly (wont visit the lakes GEG), and MSR (eating up the entire fucking budget and will still probably get cancelled). Overall, its just people in power are retards as usual, and sunk cost fallacy continues to fuck over every waking moment of this agency until congress finally says "stop this bullshit, pay SpaceX to do it 10x better and cheaper." Case in point, Psyche.

That will be $25 million per experiment ride, plus tip!

>>15807264
Yeah.
We really should only be using direct-Jupiter gravity assists, since Jupiter is the one planet that can provide an actually valuable assist.
To do a Uranus mission with minimal autism and wasted time it makes the most sense to build a nuclear electric propelled probe, throw it directly at Jupiter chemically (no outward spiral nonsense), have Jupiter's gravity slingshot it at Uranus on a fast trajectory, and slow down for arrival at Uranus using the NEP system (also use NEP for maneuvering in-system).
A fully refueled Starship sitting in LEO can do over 100 tonnes direct to Jupiter, so fitting NEP into the mass budget with lots of leftovers for instruments wpuldn't be a problem.
Just need Starship and orbital refilling working lol, lmao

>>15807273
Flyby missions are a no-no after you've done the first one, which is the case for Uranus and Neptune. A second flyby would be a waste of time.

>>15807201
Earths polar regions get less solar energy than the Martian mid-latitudes

I've been thinking about mars colonies and the main thing about them is that a self-sustaining mars colony is required by physics and human biology to be civilized and technologically advanced. If you fuck anything up on mars, you die and if you are 'self-sustaining', you aren't getting deliveries from earth to keep you alive. Only the civilized man can survive on Mars. There's no easy oil or coal, you can only keep yourself warm if you know how to facture tons of photovoltaic cells or harness nuclear power. You have to know how to manufacture a life support system and a pressurized structure if you want to expand even by a couple thousand cubic meters. And all of it must be reliable and automated. Say there's a nuclear cataclysm that wipes all major infrastructure from the earth. You can survive in the wreckage as a savage because in the end, the air is breathable, there's water everywhere and no matter what there is at least some wildlife. Thats how our ancestors survived through everything. Thats why if earth gets fucked by a cataclysm, even if hundreds of thousands of people remain, it might take centuries to return to civilization, get back without the easily obtainable fossil fuel deposits we had. On earth, we don't need technology or science to stay alive. I think thats why Elon is right to think that a martian colony is important, it isn't necessarily about keeping humans alive off world in case everyone on earth dies, its about returning civilization and infrastructure and technology to a broken world, or at least keeping it existing somewhere else.

>>15807282
there is a reason these are all drawings and not real ideas. I feel sad for people at SpaceX on the Merlin team because they have all their hard work trampled over by the millionair with the boondoggle.

https://twitter.com/RyanHansenSpace/status/1713968171554681233/photo/1

>>15807282
Martian mid-latitudes don't need to deal with a 3000 hour period of darkness. The reduced density of solar power isn't a real issue.
You are grasping at straws here.

>>15807280
Flybys are fine if you spam magsail probes; a dozen or so flown through the Uranus system would bring a scientific bonanza

>>15807288
SpaceX was always about colonizing Mars

>>15807298
>bonanza
your retarded. the world you are looking for is glut not bonanza.

>>15807286
yes, like Foundation

>>15807286
1bar pressure vessels are pretty easy, in fact the pressure improves their ability to self support. The trick is to overkill everything, like a submarine that has a 3000 foot crush depth and never goes below 100 feet, but with the pressure gradient reversed (also much less pressure differential overall).
The trick to robustness on Mars is to build tough, build big, and build a lot. If every habitat can shrug off a rifle round without a puncture, every habitat has enough air volume inside that a total life support blackout would need to last months before the air inside went toxic, and there are hundreds or thousands of these habitats interconnected with the ability to close off connections between them, it becomes almost impossible for a "whoopsie, everyone's dead" problem to occur.
However, your point about forcing some of humanity to always remain high tech & therefore civilized by settling space is a solid one.

>>15807288
At least 1/3rd of all SpaceX employees are there because they want to see Mars settlement happen, and another 50% are there to be part of the global dominator in space. The remaining ~27% are there because they want to work in aerospace and actually fly their hardware and don't care much about space colonization but don't shit on it either.

>>15807293
I was saying that Mars is a better prospect for colonization than Earths poles, you seem to be agreeing with me. Martian weather, outside of dust storms, is also far better - the wind loads are trivial and its never overcast

>>15807298
If every magsail probe cost $1M and had ten hours in-system at Uranus, then for the cost of 500 of those magsail probes you could instead build a single giant orbiter that would spend something like 80,000 hours vs a cumulative 5000 for the flyby probes, and the giant orbiter would be capable of doing better research because it can collect data uminterrupted for a long time continuously.
Also if you have magsails you have solved the issue of launching big orbiters to Uranus in a timely manner anyway, since FH can throw about 20 tonnes into Solar orbit, and from there you can get your 5 year Uranus transfer orbit with the sail. Slow down to capture using NEP and you now have a Cassini class orbiter in system.
This works for Neptune and for KBOs too btw. Fast flybys are for scouting never-visited targets (ie Eris, Sedna) to inform the instrument suite on followup orbiter missions.

>>15807314
Ah ok, yeah we agree then. Hard to tell anons apart sometimes.

>>15807321
>FH to solar orbit, Magsail to intercept, NEP to capture & maneuver in system
This means no more gravity assist windows too, which means a launch opportunity roughly once per year for everything outside of Jupiter's orbit. Only downside is that magsails don't work doing in-system (at least not well), but you also have strong solar power as an option at that point, and there's not much interesting inside of Earth's orbit anyway, so whatever.

why is starship so shit?

Just use the sun for gravity assists

why is starship so based?

>>15807337

>>15807337
Doesn't work apart from sundive perigee burns to maximize Oberth effect, but that's not a gravity assist.

If you can send a telescope to see the highly focused light of an expolanet thats 20 light years away using the Einstein ring our Sun's gravity makes, you can send a laser there to draw things on the exoplanet.

>>15807358
I don't think you could draw anything but you could use a laser to send very noticeable pulses of monochromatic light that would be very obviously artificial and could potentially be used to communicate with ayys

There's a reason that the Space Force is getting increasingly paranoid about space situational awareness. You can't hide orbit changes and they usually happen well in advance of anything on the ground.

fucking what? terraforming mars is retarded, terraforming in general is retarded for our generation. the results wont even be visible until a thousand years in the future we would just be pissing away what little funds we have for mars. not to mention relying on this being a multigenerational global project which im sure that always works out great in our modern society (it doesnt). finally, YOU ARE A STUPID ENVIRONEGRO THAT IS TRYING TO START A THOUSAND YEAR GRAVY TRAIN FOR INFINITE FUNDING WE WILL NOT GIVE YOU THE FUCKING CHANCE ON MARS.

by the time any terraforming activity is ready to begin in any actual substance, it's likely that multiple large settlements will already be established. terraforming mars will probably destroy them.
