Would it be possible to have a nuclear rocket engine that doubles as a reactor to generate electricity? Maybe if it could generate enough power, it could power electromagnets around the spacecraft to shield from radiation. It seems to me that this would be the best spacecraft that humans could feasibly build.

And I know about the risk of an RUD on launch acting like a dirty bomb, spreading radioactive material. You could solve this by launching the engine/reactor separately with its own launch escape system.

>>10762206
yeah, easy even
cooling is more difficult when you're not pouring coolant directly through it at tremendous rates, however

>>10762206
>Would it be possible to have a nuclear rocket engine that doubles as a reactor to generate electricity?
Yes, they're called Bimodal NTRs.

>Maybe if it could generate enough power, it could power electromagnets around the spacecraft to shield from radiation.
While magnets can stop some forms of radiation, the power requirements exceed what a BNTR could make, if I recall correctly. Plus, the magnets would only stop charged particles like alpha or beta radiation, but gamma will just go right through. There's also a chance that the magnets or the reactor could fail and then your crew is exposed to the radiation that they were previously safe from. It's far cheaper, lighter, and more reliable to just design the walls of the spacecraft to block most forms of radiation and then have a very heavily shielded "storm shelter" for really bad cases.

What a joke, many anons in these threads will probably have unironically died by then due to various causes.

Not enough.

>>10762310
Damn, I'm not sure I should I even finish the anime. I don't think I can handle it.
>>10762343
it won't be the same. The issue is the cooking and the cleaning anon. Can't do that in VR. It's going to be a long time before we have robots that can do that. Way too long.

>>10762532
I don't think it will be that long. I think current tech lines up pretty well for humanoid robots. We also have soft muscles in the rnd phase. Neural nets can be engaged for specific functions like picking things up.

Generally it's a complicated issue. But you might not need high intelligence for some of these functions. It might be that your food is cooked in some oven instead of hand made or something and cleaning is done by designated space.

It's doable. in 10-20 years depending on functionality and how okay you are with a robot that is socially retarded

>>10762544
>>soft muscles
I literally could not care less. Rotary electric actuators are just fine. I don't need an IRL fox girl, just something that cooks and cleans, approximating the effects of one. VR can super impose one on top. Also the soft muscles you're probably thinking of use high voltage and tend to hurt like hell if you touch them
>>neural nets
increasing neural net performance requires exponentially increasing amounts of training data. As it just so happens in robotics, said training data can only be obtained in the real world. The amount of training data could become so great that we can't economically train robots to reach human level performance. Cooking japanese food requires fine manipulation capability far beyond what we have today. You have to be able to manipulate fragile and flexible objects. You also have to do tasks we don't think of in typical robot manipulation like slicing stuff and tool use. Really if we can do these tasks autonomously we can do fucking surgery autonomously.
>>cooked in some oven
then it will just be a prepackaged overprocessed TV dinner. I'm feeling depressed just thinking about that.

>>10762569
I mean most humans can't do japanese sushi justice. They train for years. But could we have a robot using soft muscles on a solid state battery that can pick objects up and put them in other places based on verbal(ish) commands
Eh, maybe

Also the soft muscles I was talking about were the oil based ones, something similar to hydraluics. If you threw enough capital at this problem and combined enough tech it's possible to get something limited.

Also who knows if mlm advances further, considering current capital it's plausible

>>10762200

When I said the flag belongs to Boeing, the proven traditional way to access space and a company with decades of experience and success behind their backs, everybody here laughed at me calling me a shill.

As a Boeing guy I am proud and I am not ashamed to "shill" for such remarkable company because I know when you are doing something you have to do it right.

The race is settled. Starliner will be a full duration mission while the inevitably delayed dragon is a demonstration to see if there are any other jarring explosive problems with the clearly improperly designed capsule that could risk not only the astronaut's lives but also the very space station itself.

If it were up to me I'd require multiple uncrewed flights from the dragon over the next years to confirm there is minimal risk for human live or one of the most valuable engineering feats ever made, but sadly it seems spacex lobbyists have succeeded in smothering reason and safety for their own interests.

I can only hope these outright malicious actions do not lead to catastrophic consequences.

>>10762729
How many flights has Starliner made, again?

How were NERVA and RD-0410 supposed to be stopped? You can't just switch the running reaction off, can you? And they were using the cryogenic fuel as the coolant, so in space they could have only been cooled when running, right?

Speaking of cryogenics, how does one prevent the liquid hydrogen from boiling off in space? Same question for methane and oxygen, although this is probably easier

>>10762459

>>10762846
>how does one prevent the liquid hydrogen from boiling off in space?

You don't. You may reduce boiloff by keeping it cool through various means see ACES for potentially longer lasting hydrogen upper stage.

>>10762894
To be fair towards NASA, Dragonfly is unlike any probe made ever. So it makes sense that it'll take a while to develop and make. NASA just can't make a small reactor and a quad-copter from Walmart, and strap them together. Also, NASA probably got funding for only one probe, so if it messes up and crashes into a methane lake, then that's it. NASA can't use what they've learned from the mistake to make Dragonfly 2.0, because the US government most likely won't fund another probe. That's just the sad reality of most space programs, they're so expensive that one can't figure things out by trial-and-error . Instead, they have to focus on getting 100% reliability on each mission, even if the budget gets blown up, it'll still be cheaper than doing it the trial-and-error way.

>This is why kids don't care about space.
Spaceflight being slow isn't the only major reason people don't care about it. Even during the height of Apollo, a little less than half of Americans were against the program. The public's disinterest in space is deeper than just it being slow.

>>10762121
Is there any reason to think that emergency reentry measures like MOOSE and Paracone would not have worked as designed? The testing was not sufficient to prove the concept but that's not the same as disproving it either.

>>10763121

>>10762643
Soft muscles won't help with aforementioned manipulation problems. It's more of a software than hardware problem. We have many of the same manipulation problems for other types of cooking. And those oil based muscle use high voltage and can give you quite the nasty shock.
>>10762957
>>10762894
a big part of it is travel time. It takes 9 years to get to Saturn. Galileo, Cassini, and New Horizons also took a long time. If we don't start today, we won't have them tomorrow.

>>10762846
>methane and oxygen
solar shade and some refridgeration
maybe some heating or you'll freeze your methane

>>10763106
it would totally work, but you'd end up in the middle of the ocean which would suck
>>10762846
you just shove the control rods back in and then have a fuck-huge radiator, which you need anyway because the propellant exits at several thousand degrees so that's as cool as you can make the reactor

>>10762846
>You can't just switch the running reaction off, can you?
Yes, you can.

>>10762121
If Gemini does not remain your favorite spacecraft, you need to rethink your entire approach to life.

>>10763211
nah mate it's Apollo ontop of Saturn IB, such a piece of shit and it worked beautifully

>>10762957
>Even during the height of Apollo, a little less than half of Americans were against the program. The public's disinterest in space is deeper than just it being slow.

Can you source that? All I can find is data showing that support for the program hovered just under 50%, but without the data on how many were opposed, and how many undecided, that doesn't really tell me much.

A interesting related bit of polling data emerges when they asked people what percentage of the federal budget went to NASA. According to the article cited below, folks have tended to believe NASA received about 22% of the federal budget. The actual percentage peaked at just over 4% in 1965, and has been under 1% since the 70s.

That misjudgement of reality would make judgements of whether people support or oppose NASA and space exploration expenditures trend more towards those who believe it is not worth what we spend on it.

I'd love to know if any pollsters ever did the obvious thing, and followed up with "The actual expenditure for NASA is around 1% of the budget. At that cost, do you support or oppoe the program?"

>>10763106
The principle is solid, and the control system for more precise landings isn't much of a problem these days. (would've been tricky at the time probably though). Problem is, such a system doesn't offer any advantages over a capsule. An expandable parachute like this on a manned capsule or a planetary lander is a good fit for many missions. For humans, you will have your spacecraft anyway, why not use it for EDL.

>>10763211
GOCE is my waifu. So sleek and aesthetic, and is almost a spaceplane (if only they've been actually using that lift they measured)

>>10763106
There's no reason to think MOOSE wouldn't work, but it's an absolutely terrifying concept and I would never want to have to use it.

>>10763318

>>10763318
That's a fallacy. The same can be said for a tin can with astronauts plunging into atmosphere at 22M, surrounded by a plasma ball. The same can be said for a huge plane doing the same. The size doesn't really matter, the question is how well it's designed and tested.

>>10763321
Well, Alan Eustace jumped from the stratosphere in a aerodynamically stable suit not unlike this, albeit much smaller. He had to make a company for designing it, and they offered the jumps in that suit, but never been able to attract any customers AFAIK.

I'm sure we'll see a similar descent system someday, if it will make sense. It's just right now there's little point in it.

>>10763331
Bigelow habitats are meant to be reinforced with skeletal structures from inside, I believe. Anyway, there will always be a capsule docked.

>>10763229
It is just sad that so many people have no idea on what the government actually spends money on, and think that all the money spent on "flashy" programs like space stuff could somehow fund super large welfare programs or what-have-you. When of course we all know that NASA's ~$20 billion budget is a rounding error compared Social Security or Medicare/Medicaid.

>>10763302
>>10763106

Interesting historical side-note incoming:

In the earliest days of manned space flight development, there were no real international rules or even consensus regarding what would count as a successful flight in space. The closest thing the world had was the Fédération Aéronautique Internationale, which recognized things like altitude records, speed records, duration records and such for aircraft flights.

For the first nation to fly a manned space mission, you didn's want a bunch of airplane enthusiasts in Cheesistan claiming your flight did not count. But their certifying your new speed, altitude and distance records would be very useful to you, in the propaganda needs of the day.

One bit in their rules requires that a flight is not successful if the pilot does not land the aircraft.

This posed a problem for things like >>10763106, as well as for the Soviets who for various reasons needed to use a system that saw the cosmonaut eject from capsule before landing and make a separate descent by parachute once re-entry was acheived.

This is why the Soviet accounts of Gagarin's flight all initially claimed he had landed in the Vostok capsule. They continued to lie about that until it became clear that the world did not give a rat's-ass about whether the crew landed in the capsule, and that Gagarin's flight had been well (and rightly) accepted as the first manned space flight. The world seemed to understand that space flight differed in fundamental ways from anything to do with airplanes, and that rules for recognized record-breaking in airplanes had nothing to do with records in space flight.

>>10763389
Now, how about a nice cup of rage!?!

The conspiratards are ready to explain to you that Gagarin never flew.

>Well, Gagarin was not at all flying, because he only is in a parachute jump suit and not in a space suit, and there is not only one photo, but there are several photos after the alleged landing - with parachute jumping suit. Gulag "Soviet Union" has presented a big lie to the world. Gagarin is only a parachute jumper.

SpaceX targets 2021 commercial Starship launch
https://spacenews.com/spacex-targets-2021-commercial-starship-launch/

Jonathan Hofeller, SpaceX’s vice president of commercial sales, said the company is in talks with prospective customers for the first commercial launch of that system roughly two years from now.
“We are in discussions with three different customers as we speak right now to be that first mission,” Hofeller said at the APSAT conference here. “Those are all telecom companies.”

Hofeller said SpaceX plans to do several test flights before using the next-generation launch system for satellites. Those test flights — a number he did not quantify — are to demonstrate the launch system for customers and to assuage any concerns by insurers about the reliability of a new vehicle.

“We have future hops coming up later this year,” he said. “The goal is to get orbital as quickly as possible, potentially even this year, with the full stack operational by the end of next year and then customers in early 2021.”
“Falcon 9 and Falcon Heavy are going to be around as long as our customers want them,” Hofeller said. “If we make them obsolete by having a better product and a lower price, great.”

Hofeller reiterated that [launch] prices would keep dropping through the introduction of Super Heavy and Starship. The fully reusable nature of the launch system enables those lower prices, he said.
“You could potentially recapture a satellite and bring it down if you wanted to,” Hofeller said. “It’s very similar to the [space] shuttle bay in that regard. So we have this tool, and we are challenging the industry: what would you do with it?”

Hofeller said SpaceX plans to reuse a single Falcon 9 booster five times by the end of this year.

>>10763729

Imagine using starship as a temporary space station. Send it up, deploy the solar panels, and sit up there for several months doing whatever needs to be done, before bringing it back in.

Update from @SpaceX on the 60 Starlink satellites:

- 45 in final orbits
- 5 still raising, in final orbits shortly
- 5 paused during raise for adjustments, will continue
- 2 intentionally being deorbited to show debris disposal
- 3 stopped communicating, "passively" deorbiting

>“We have future hops coming up later this year,” he said. “The goal is to get orbital as quickly as possible, potentially even this year, with the full stack operational by the end of next year and then customers in early 2021.”
Are you telling me that those scrap heap prototypes are SSTO after all? Make up your mind SpaceX.

>>10763797
starship could do ssto, but it would barely make it and not be able to carry any cargo with it, making it pretty much useless

Need the big dick to bring shit

>>10763763
Space stations need years of careful planning to optimize every nook and cranny to build the ultimate controlled environment that will safely house the highly fragile experiments it will run over its lifetime. No respectable scientist will even consider suggesting using an experimental tincan welded by plumbers that might not even fly in the next 20 years unless scaled down to reasonable sizes and built per industry standards.

Gene Cernan was supposed to ride one of these but he couldn't use it because of exhaustion and poor vision

The space suits they wore for evas on the gemini missions were horrific. Bulky, hard, you'd have to exert enormous amounts of effort to move

They attached the device to the back of the craft, and you'd have to climb all the way to retrieve it

We probably won't even see a Titan mission arriving sooner led by some random youtuber funded Mountain Dew-Doritos that just lands a Go Pro and a can of Moutain Dew TitanXL Gamer Fuel TM xXxDumbYoutuber234xXx edition.

I am going to say the magic words that should not be said

I am fully aware it would be an absolute shitshow trying to integrate it

Starship–Centaur

>>10764275
Yeah fuck that noise. SpaceX would have a better time of simply shrinking Raptor down and mating it to a F9 upper stage and using that for a deep space kicker.

WHERE IS RAPTOR
IT'S FRIDAY

>>10764282
Raptor isn't nearly as efficient as a proper hydrolox stage. It's really good in a lot of ways, but it's not competitive here. You'd also be designing an entirely new stage instead of just sticking Centaur in Starship's payload bay (or whatever we're calling the chomper meme)

>>10764275
I want it

>>10764275
you know it's the absolute sort of bullshit that NASA would try to pull for deep space probes instead of just expending a star-kicker

>>10764292
What about Starship-Centaur-Star?

We have 100 tonnes of upmass to play with, we can literally just stack boosters like it's fucking Kerbal (as long as they fit inside Starship)

>>10764294
four engine Centaur-8

NO
FUCK IT
STARSHIP-ACES

>>10764299
refurbish an S-II from the rocket garden and put it on top of Starship

I think people don't fully grok the nature of Starship. It's a spacecraft that's meant to be refueled, and refueled... — just because it can't throw something in one go doesn't mean you can't throw it with some tankers

>>10764299
Adding engines to upper stages trades delta V for thrust.
Starship Centaur Star would probably be the best bet.

>>10763122
>>10763122
gods I was strong then...

>>10764309
See how it peaks out at 9km/s dV even when fully fueled in orbit? That's not enough. You'd need to, like, put it on a heliocentric orbit and ship fuel to it there

>>10764178

>>10764311
but anon
BIG CENTAUR
>>10764309
so you, at most, get like 8 km/s past escape, which is pretty crazy

>>10764313
and? Mid-millennia explorations around Africa to Asia had to stop in buttfuck nowhere South Africa to stock up. Space will be the same.

>>10764317
At which point you're designing a whole new stage anyways. Might as well go with a modified Raptor to simplify ground ops.

>>10764323
if you're not going to do a prop change then there's no point to using a separate stage for it

>>10764317
>BIG CENTAUR
Or just keep stacking

>>10764326
Superheavy and Starship to get the kick unit and payload into space and into a preliminary escape orbit, then the kick unit can decouple and fling itself out where it needs to go. If need be, slap a Star unit on top for even more get up and go.

aren't we forgetting? Elon has laid out the plans for a specialized high-performance starship mod. Was in terms of starlink probe things, but mass is mass.

>Massive delta velocity slam from highly elliptical Earth orbit using a fully retanked, but lightened up Starship with no heat shield or fins/legs. Best choice for the impatient. Ion engines are too slow.
>Probably no fairing either & just 3 Raptor Vacuum engines. Mass ratio of ~30 (1200 tons full, 40 tons empty) with Isp of 380. Then drop a few dozen modified Starlink satellites from empty engine bays with ~1600 Isp, MR 2. Spread out, see what’s there. Not impossible.

>>10764327
that's nonsense and Elon swore he'd never do something like Falcon Heavy again
You don't really understand Starship at all

>>10764331

>>10764332

Dont we have semiconductor tech capable of running at those high temperatures without failing?

>>10764275
At least the starship doesn't have people onboard, so it might not be as bad as you'd think. Of course there might be some other issues relating to Titan being in the right season and earth being in the right place.

NASA's begging congress to let them launch Europa clipper on a rocket's that's not SLS, even though funding is contingent on them launching on SLS. Fortunately, this mission, like most other NASA missions, is not even considering the launch vehicle at this point in the design stage.

>>10764401
if you can have silicon remain semiconducting at 450°C, then yes

The LLISE probe also intended for venus is supposed to have SiC circuits capable of thousands of hours of operation at 500C

Zubrin's "what if we just continously eject a reactor as reaction mass" nuclear torch drive

>>10764450
Yes, we have silicon carbide semiconductors. The issue is they are about as good as 1960s electronics. The other issue is that electromagnets don't work that well at these temperatures. Temperature increases the resistance of coil windings and makes magnets less powerful, so over all they are less efficient. We do have motors that work at these temperatures:
https://honeybeerobotics.com/portfolio/hottech-venus-motor/
The idea here is that the rover could use wind power directly to move the rover around. If we just make our rover so all it does to avoid obstacles is bump, reverse, and turn, we can completely eliminate the need for electrical actuators. Then we can have some simple solar powered(yes solar panels work at these temperatures!), electronics that do all the science and are just along for the ride. It's sort of hard to do the visual navigation because it's hard to make a digital camera with SiC electronics. NASA did have a competition to develop a mechanical camera that could take pictures with a single light detector. Pic related is what the challenge was. Make a camera with one rotating input that takes a picture with a single photodiode. You're only allowed to use op amp and three wires for output, or like two rotating mechanical outputs, you have to take the picture in less than 5 hours, you can use absolutely anything you want to reconstruct the image from signals.

The advantage is that its only 200lbs while a capsule weighs 100x that. Its an emergency craft. A space parachute for situations when you either don't have or can't use your regular craft such as in a repeat of the situation that lead to Columbia.
>>10763350
ILC Dover did the actual suit design and production and Paragon did the PLSS. It was all very much a one off contract done for StratEx. Never saw anything about them trying to shop the experience around though. Got links?

>>10764358
nuclear pulse propulsion's cooler. It's sort of like a pornstar though, nice to fap to, but not exactly marriage material. LANTR on the other hand, now that's marriage material. Nuclear bomb propulsion can take off from the ground, but LANTR can do it with much, much, much less release of radioactivity. LANTR can potentially be reusable too. Although you have to invest in some pretty interesting hardware for handling it on the ground because you can't shield the whole reactor. As in people can't get anywhere close to it while its on the ground, the radiation damages machines close by, and you have to clear away dead birds and bugs. The US airforce actually did some pretty fun experiments on this for their nuclear aircraft program with an unshielded 10 MW reactor.

the last of the four RS-25s arrived at MAF today. they're going to start installing the engines next week.

>>10764592
yeah, although with this rover they want it to go on a relatively straight path, rather than just driving in circles. This way it ends up going across a certain geological feature on venus. Damn driving in straight line off terrain is fucking rough though. Venus doesn't have a magnetic field so compasses don't work and Venus' rotation rate is so fucking slow that gyrocompasses are impractical.

>>10763906
>I just really wish they'd stop screwing up human spaceflight with it
I mean OmegA isn't going to be man-rated. The only truly retarded application of SRBs in manned spaceflight was the Stick (aka Ares I). Everyone pisses on the shuttle SRBs, but they've NEVER failed within their design parameters. They only blew up because management ignored the engineers saying "this is absolutely not safe."

Man I really want to know how this can work at all or what pharmaceutical substances were consumed in the conception of this idea:
https://www.nasa.gov/directorates/spacetech/niac/2019_Phase_I_Phase_II/Power_Beaming/
TL;DR power a probe on the Venusian surface with microwaves beamed from a balloon higher up. Seriously how the hell does this even remotely work? You can't keep a solar powered airship in one place above 10 km on venus and they most definitely want their transmitter above this height:
https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20060056388.pdf
So their balloon transmitter thing's gonna blow around with the wind. At best it might even go around the planet and get with in range of the probe a couple of times, but they're probably going to need propulsion to keep it from drifting too far off. We know venus' winds probably circulate in the direction of the planets rotation at least at the cloud tops, but there's also the possibility that closer to the ground, where this thing's supposed to operate, they may circulate differently. We don't know much about the wind at this altitude cause far as we can tell there's not much shit in the air our satellites can look at and follow. Then there's receiving the beamed power itself. We've made rectennas that can operate at 2.45 GHz and 300 C, but the efficiency was like 9%. It's believed that at 450C the efficiency would be much lower. Just what are they smoking?

Just stack reaction wheels and batteries I guess, not realistic but it works. You can put 'em on your boosters and ditch them during launch to save weight, since you don't need them as much after 30-40km. That, or vernier thrusters for bigger vehicles.

That's the completed tankage of the core stage. When they get the next stage to that step of work (CS-2 is currently just in welding), it'll be sitting in the same place as that one (and the one you see in the picture will be long-gone.)
The core stage in the pic is waiting on the engine sections, then it's essentially done, and will be shipped off to Stennis to be tested, before being sent to KSC for stacking.

Elon should go on the 2nd manned Dragon2 flight. Eat a really big weed brownie. Then just live stream himself high in micro gravity.

>>10764824
It's pretty much entirely driven by rocket lab, which is technically a US-registered company but set up and staffed mostly by kiwis. The NZSA is now pushing hard to make the country an attractive place to set up space start ups, and seems to be having reasonable success, with Rocket Lab offering relatively cheap smallsat to orbit capability.

It is almost the same as hydrogen advantage in specific impulse gets compensated by higher density of methane. A simplified and expendable Starship variant would be an absolute powerhouse for launching heavy probes to outer solar system.

the true boundary of space should be where the earth atmosphere becomes indistinguishable from the interplanetary space, which is approximately 1500km at most.

I would assume they would use a similar method to what ships do to remain stationary in the ocean. Have orbiting satellites give GPS.
Also surface levels on Venus are only a few km/h, not the nightmarish hellscape that is the middle layer where you are rocking 40x our atmosphere blowing at 700 km/h.

thats exactly what happened. as soon as the airforce pushed the shuttle meme NASA was put on life support because congress didnt want to pay for both of them.

new thread
>>10767650

>>10767649
What I meant was that it wasn't a case of Congress wanting to cut budgets, but that there was fears that if NASA had a slim chance of sending people to the moon and beyond then they would constantly push for it. Simply dialing back NASA's funding and telling them to only use their equipment for LEO wouldn't be enough, NASA had to be shackled to LEO and the Shuttle was for that. A new vehicle with barely enough funding to get off the ground, while everything Apollo was either scrapped or sent to museums, so NASA couldn't to back to the moon even if they wanted to.

I'll head back to the tin foil aisle.

>>10767068
Wow, what equipment? Image stacking?

>>10767655
