When travelling to mars on Starship, radiation is going to be a big problem. I'm guessing that a good way to deal with radiation is to keep the vehicles ass pointed at the sun so that the fuel tanks soaks up all the radiation. Is there any better method of stopping radiation with Starship?

People that eat meat don't live less than vegans or vegetarians despite all your graph shows about protein and cholesterol. All you're doing is exchanging one disease that will kill you with another disease that will still kill you. The rest of the graph you show is manipulative. Meat only has a greater impact on the environment because of factory farms, the greenhouse gas emissions is pure propaganda and a misunderstanding by certain animal rights groups on carbon gasses in the atmosphere. Soil is proven to be improved by grazing animals and livestock is right now being used to reverse desertification. Since you're probably new to the idea I'll post a link

>all the scientists are wrong because this random Japanese magazine says so.
Might as well believe what Shell and Exxon say about climate change.
It's simple physics.

Plants -> animals -> humans

>>12208876
No. I think so because I have a degree in Earth science and took classes on the atmosphere. You probably don't even know what an atmospheric reservoir is or residence time. You think cattle gets its carbon from space? You think cattle invents carbon from nothing? It gets its carbon from the plants that gets it from the atmosphere that gets it from the cattle. It's a net change of 0. The only concern is CH4 is more powerful a greenhouse gas than CO2 but even then the residence time of CH4 in the atmosphere is only about 8 years before it breaks down to CO2 and reenters the carbon cycle or gets captured into a carbon sink. The only way eating meat disrupts the cycle is when factory farms introduce fossil fuels through fertilizers and transportation.

The rest of your post is irrelevant. We know livestock improves the soil and stops desertification. Once we reintroduce livestock back into an environment what are you expecting we do with the extra livestock? Didn't think that far? Our choices are: Introduce predators, which is instead of killing them yourself hiring another species to do the murder for you; shoot and eat them yourself; shoot them and leave their carcass to rot in the sun; or let them die a horrible death of starvation, very noble of you.

Stop arguing please, you obviously have neither the education nor resources to continue.

>>12208861
>Meat only has a greater impact on the environment because of factory farms
Factory farms are the norm across the developed world, and less than 5% of all US cattle is grass-feed at all.

Vegetarians and Vegans like to ignore this fact but all historical records show that people in civilizations with seafood culture lived and still live the longest to this day. A seafood diet is every similar to a vegetarian one but you add fish/shrimp or other seafood twice a week and eat meat only once in a while. There is literally nothing healthier than that and if you still eat vegetarian or vegan despite knowing this, it's because you're a cuck who doesn't want to face reality.

Ironically if they'd gone with the F-1B boosters and funded EUS properly, SLS would still be the best way to get cargo to the moon without orbital refueling. SLS Block 1 is just an all around pointless rocket. Maybe they'll revive those Orion plans via commercial rockets when Starship lands on the moon and destroys SLS's entire reason for existing.

>>12209906
Kinda similar, but I always liked the idea of SLS (or DIRECT, technically) being an actual replacement for the Shuttle, complete with its ability to send big payloads/modules to the ISS.

NASA astronauts had first view of Starship.

>>12209906
The F-1B pyrios boosters were always a block II concept, weren't they? There's a chance it still gets revived after they finish the Block 1B upper stage sometime around 2035.

>>12209948
I really want to see SpaceX divert some resources to a side project offering a new Advanced Booster design using Raptors and propulsive flyback. You'd probably want ~9 Raptors per booster.

>>12209979
Isn't that Super Heavy

>>12209913
DIRECT was awesome because it actually felt like reuse of shuttle material. Remember, Shuttle stuff isn’t inherently THAT bad. The shuttle ET cost $75 Million. The boosters were $70 Million for both, and the SSMEs were $60 million apiece.

A Jupiter rocket with 3 SSMEs would likely cost around $380 Million, assuming that $30 million is spent on stuff like the fairing, guidance, etc, and that $25 million is spent on new plumbing for the engines.

>>12209997
I would also like to add that this means that a Jupiter-130 costs as much if not less than the Delta IV Heavy, but can put 70 Tons into LEO! If you take off one SSME but add a centaur, you can now put like 20 tons into GEO versus the Delta IV heavy’s 6 tons.

>>12209957
i know it sounds stupid but they COULD just launch orion on starship. if the bellyflop still hasn't been man-rated but everything else is good to go then why not?

I hadn't watched that video actually, I just quickmaffed how many Raptors it would take to equal a Pyrios

>>12209997

The problem with DIRECT is the same problem SLS had - adapting the ET to take top loaded payloads is not as easy as people thought.

>>12210005
>launch Orion on Starship
Uh, how? Just stick it on top of an expendable SN core? I mean they HAVE shown that they can shit out Starship tankage like it's nothing.

>>12210005
This. Starship is amazing even if the second stage (the ship) is expendable. If Falcon 9 is 3.66 meters across and had a 5.2 meter fairing, then 9 meter Starship can have a 12.8 meter fairing. This gives about 12.2 meters of internal diameter... which means that we could conceivably launch a 10 meter monolithic mirror for a space telescope, or a 17 meter mirror for a segmented one.

Also Raptors are $2 Million apiece. Because stainless steel is $3/kilogram, it is likely that expendable Starship costs like $10 million dollars or less if you’re flying with 3 raptors.

>>12209927
Wish me want to fly that plane on MSFS in that same flight

>>12210020
Just put it inside a cargo Starship's fairing. Centaur and a payload fits with meters to spare.

Autistic spaceflight question: would a soft docking tube like this work? I'm trying to design a way to attach a starship to another hab/engine station and have them connect. I know starship can attach at the ass but you can't really cross over directly into the station if that makes sense

>>12210020
Just fit an Orion + DCSS inside the nosecone and you can send it off on TLI. Lunar reentry and refueling might take a while to iron out for Starship anyway but it could do Artemis 2 faster than SLS could if you just use it like that.

>>12210037
if you have enough faith in your spacecrafts' station-keeping to not bump into each other, sure. but there isn't really any need for it today now that we've mastered docking large spacecraft to stations. when that was drawn there were serious concerns about the difficulty of it.

there were rumors the soviets had something similar planned for their manned lunar program where they would launch their flyby/landing craft on a proton/n1 and then use a regular soyuz to dock with it after it had successfully launched.

>>12210067
>crew is stored in the balls

>>12210054
you might man-rate starship for launching to LEO before you have it man-rated for lunar reentry (or any reentry). nasa might not like the idea of astronauts sitting around in orbit waiting for refueling flights which would be subject to the same weather/ground equipment delays as every other launch.

beyond that, just because starship can get to orbit doesn't mean it's going to instantly be a manned spacecraft. flying orion on it could fill the gap while they get the interior sorted out.

>>12210092
Why not launch Starship into LEO, then have Orion fly up on Vulcan?

If I want to work in aerospace (Currently BS in Mechanical Engineering working in the offshore industry) would an MS in Aerospace/Aeronautical/Space systems engineering help? I have an interest in going to grad school anyway

>>12210114
I'd like to say refueling an entire and possibly expending a starship would be a waste compared to expending 1 DCSS but it might actually not be. I'm just happy with any outcome that doesn't involve orange rocket.

>>12210129
It would help you be competitive in more specialized parts of the industry, but it’s definitely not a necessity if you just want to work in aerospce. More MEs work in aero than AEs.

>Post-Cold War revelations confirmed that the film type used on AMS, known as “ASh” by the Soviets, was actually unexposed film that was repurposed from a CIA reconnaissance balloon (from Project Genetrix) that had drifted into Soviet territory in the late 1950s. This film had been stored at the A. F. Mozhayskiy Military Academy in Leningrad when the space camera manufacturers at the VNII-380 institute had stumbled upon it. Further investigation showed that the temperature-resistant and radiation-hardened film would be perfect for the AFA-Ye1 camera, and the rest

>>12210048
My thoughts exactly. Im the autist trying to create a mockup of Nautilus with Starship. I'll have it docked at the front but Idk how the crew would transfer. Starship CAN dock at the ass but I have two problems a) how would the crew transfer over to the inflatihabs (so far I'm going with a softdock tube)
and b) should we be worried that starship's engines will be pointed at the rest of the ship? Also it seems like a waste to dock a starship and then not be able to use the engines on the thing...

>>12209948
Block 2 is super not happening

The early Luna launches were one of the most bruteforce things you'll ever see. They didn't want to mess around with cold-starting an engine in space and the Luna rocket was big enough that they didn't need to worry about optimal once-a-month trajectories so they just yeeted it straight from the pad to TLI over the north pole in one big burn.

>>12210185

>>12210171
The nose is gonna be covered in tiles unless it's a space-based variant like moonship.

>>12210167
I think that's what they're going to have to do in the long run. What would you need starship's engines for? They're way too strong for a reboost. I guess if you wanted to send Nautilus on a TLI...

>>12210232

Isn't the whole point of the Nautilus concept deep space exploration?

>>12210232
>>12210167
I got it. Dock dorsal, where the cargo door is. You'd need a little dogleg truss structure to get the center of mass aligned, but it would work.

>tfw you get put on the boeing team

>>12210247
You're right, I just always thought it was the neat-looking station design.

>>12210264
Nautilus is designed to sit at the EML2 and used its plasma engines to get to high mars orbit (probably around Deimos). From there, you’d use a regular chemical rocket to ferry down to LMO. Once you reach the nautilus again (still orbiting Deimos), you power up your electric engines and fly back to the EML2.

Pic related is a more “modern” version of the nautilus. It takes 20 tons of chemical fuel (MMH+NTO) and 20 tons of Xenon to go from the EML2/DRO/NRHO to high mars orbit and back.

What if we bought nukes from North Korea and exploded them in giant underground water reservoirs to create steam for power generation to fight global warming?

>>12210278
If you're gonna orbit it around Deimos you might as well land the thing

please spoonfeed me about the ass-to-ass docking meme

>>12210387
Take two Starships
how do you dock them?

>>12210387
Starship fuel transfer happens through connections in the rear of the vehicle. Hence, starship does refilling by pushing propellants back and forth forever, ass to ass

>>12210387
>>12210403
A nice side effect is that if you have the ability to move propellant in from the bottom, it means that you can hook those same connections up to Superheavy on the pad and fuel both stages at the same time. Simplifies the GSE and makes it that much faster to refly.

>>12210167
Easy: Just assemble the nautilus as a permanent orbital ship and just dock two starships on the side as landers.

The DST concept is cool for using solar electric and hypergolics rather than exotic technology or nuclear, but 20 tons per mission is a LOT of Xenon to shit out the back of a rocket. It would be much better served with a plasma thruster system that could use more abundant fuel and is less of a power hog... especially combined with a plasma magnet sail. I really like the Helicon Double Layer Thruster for this since even without superconductors you can get it up to ~1N/kW (about 300N with DST's solar panels at Mars), and use CO2 for propellant so you can ISRU via aerobraking at Mars.

>>12210491
True but they were actually super conservative with their design. I’m a huge fan of the DST even though Starship blows it away.

DST used mostly off the shelf components, or at least stuff that works as-is. We already know that ion engines can work and we know that transferring hypergolics is possible. DST just scales up the technology a lot. In this, the Gateway actually makes sense - the Power and Propulsion Element was a stripped won version of the DST bust with 4 ion engines instead of 20 and 50 kW solar arrays (instead of 450 kW). It also lacked chemical engines, but was designed to test the ability to transfer Xenon fuel, use hundred-scale kilowatt wings, etc.

>>12210501
The HDLT has been tested extensively in the lab, including with CO2 propellant. 4ASS needs to build a demo smallsat once Starship makes them cheaper. Plasma fartcan tugs are the future of cislunar space.

>>12210335
Ion thrusters suck huge, irradiated horse penises at entering or exiting gravity wells. Leaving them in orbits that don't take a lot of delta V to break like EML2 or Deimos saves you like 50% on travel time.

Huh. didn't know my thread was even up anymore. but I guess I'll just repost some of the Luna 3 stuff from previous thread:

>>12210551
These predictions were pretty close as well. Although the later ones never came into fruition.

Artificial moons 1957-1962
Artificial moons orbit the earth gathering data and scientific experiments. A larger, permanent station could be designed, if the recent documentation of radiation will seem safe.

Manned flights 1959-1962
The first phase in mans space travel will be high altitude rocket planes, which can reach an altitude above 150 km. but will stay only for a short period. On these flight we will see a human's relation with weightlessness and other extras of space exploration. Currently in testing is the Lockheed X-15 in the USA

Unmanned probing station to the moon 1961-1963
In about 3 years it could be possible to send an automatic radio controlled expedition to the moon to measure things such as visuals, temperatures, radiation, magnetic fields, gravity etc.

Manned lunar flyby 1965
Here's where American and Russian estimations diverge significantly. Americans are careful and estimate us to be this far in about 5 years, while Russians are talking about a smaller timespan, even possible by now. Americans believe it to be pointless to send a man onboard, since a robot can do the same job - maybe even better. The only reason to send a man onboard would be the "sense of adventure"

Man on the surface of the moon 1970
A careful estimate says that man can land on the moon only in the year 1970 or maybe a few years later. Then we might figure out many of the mysteries surrounding the moon; is it a part of earth that came off, what is in the lunar craters? etc.

Venus and Mars 1980
No time estimations of interplanetary travel have been made, but it can be said, that these travels may begin in about 10 years after the first manned lunar landing. Then it would be possible to utilize all the technological advancements for these travels. Then the only limiting factor would be time and... money.

Kind of chilling how right they got it.

>>12210554
Interesting is that they see a lunar flyby in 1965. There were plans to use a Gemini to fly by the moon in 1966 or 1967. Neat.

Spaceflight news would be dead without SpaceX...

>>12210554
Here's some of the most interesting speculations about Mars

"Can there be flora on Mars? Yes, says a recent study. It is known, that Mars has a very thin atmosphere, equivalent to Earth's atmosphere at 13 km. It's consistency is slightly different to ours, since oxygen is almost completely missing and the air is made of carbon dioxide and nitrogen. This does not rule out the possibility of plant life existing, since they require carbon dioxide and emit oxygen. Animals and humans instead require oxygen, so it's improbable for mars to have them, unless humans there have become so advanced to be able to chemically extract oxygen from other chemicals.

Latest studies have even shown, that light refracts from Mars is similar to lichen and moss. This would prove, that at least plant life would be found. Science usually doesn't guess, but uses facts and studies to draw their conclusions. But from Mars there have been many guesses, which seem very plausible.

It's been suggested that Mars could be a dying star, drawing it's last breath. Oxygen would be depleted and it has been suggested that the red color of Mars would be the result of oxygen bonding with the iron at the core, and forming rust, and the atmosphere being so thin, it could not stop the large changes in temperature.

If there are any humans on Mars, they would have to live in tightly closed off areas with oxygen heat. Scientist also say, that it is very possible that the life on the planet may be completely alien to us. For example, it it completely possible that animals there breath carbon dioxide instead of oxygen.

So when we go to Mars, we can expect almost anything, possibly we'll find a deserted, dead planet, where days are hot and nights freezing cold, and where only in the summer on the equator we may find moss growing. But we may find at the bottom of a ravine the remains of great ruins, which prove the existence of a highly developed civilization, which once lived on this planet.

Anon, are you fucking stupid? The issue with cattle isn‘t that they turn Plant carbon into CO2, which gets used by plants but somehow they miraculously make more of it. The problem is they take carbon and make methane out of it which they belch up while digesting. Methane doesn‘t get used by plants and is a much more potent greenhouse gas than carbon dioxide. Climate effect gets measured in co2 equivalents. So that is why a cow manages to make more co2 equivalents from the same amount of carbon as other animals.
I don‘t know why I even have to explain this. You are obviously retarded and the fact that you haven‘t even taken the two minutes to look this up before trying to post from a position of expertise means you live up on dunning-kruger mountain.
This is further enforced by the fact that you think one single class you took once makes you smarter than every professor working in the field of climate science put together.

>>12210579
It’s interesting that they seem to assume the default case for intelligent alien life on the planet is just more humans. Was that common at the time?

Probably, but its yield was only 10 megatons. Most of the bomb was just a cryostat.

that's still one of the largest bombs ever detonated

>>12210704
Tsar Bomba was a viable 100 megaton (10 times the yield) design at, assuming an excess of 120 tons, 1/5th the mass. Whether its big or not is immaterial; bigger has been demonstrated in a smaller package and lower weight.

Thank you guys. Really cool ideas. The concept I am going on will use Starship docked with Sierra Nevada habs. The hardest part now is going with some sort of plasma or chemical engine or something to get you to Deimos. This, in my opinion, is such a cool idea. It gets you a LOT of internal living room for a long ass trip, and this “station/ship” could go in orbit around Earth, the Moon, Mars, Venus, etc. Will make a better mockup someday soon but so far this is what I’ve got.

Wouldn't you want to dock the Starships in opposite directions to keep the center of mass in the middle?

shouldn't the Starships extend their solar panels? they should come out from under the engine skirt, but only on one side (for balance)

>>12210813
kek

>>12210814
Their orientation was literally only so that their windows could face forward. You could probably add more mass to the bottom... or orient them a different way. Actually now that I think about it you probably want their engines to face backwards (toward the sun) so anyone inside gets the passive radiation shielding. Also I'm missing radiators and other habs on the top and bottom and stuff that could balance it out

>The failure was traced to the Centaur boost pumps, but the cause remained unclear. The prevailing but unproven theory was that ice or debris caused the failure. To reduce the chance of a second failure, pre-launch procedures were implemented to verify that Centaur's pumps were free and unobstructed. Nearly four years passed before the cause of the failure was determined: an improperly installed mounting bracket inside the liquid oxygen (LOX) tank. This bracket held a LOX regulator in place. The technician responsible for installing it had found that the normal tool used to screw bolts into place was too short to reach the bracket. He thus used a slightly longer socket wrench that gave him more reach. Before the technician retired, he failed to inform his successor about this. When the new technician attempted to attach the bolt with the wrench specified in the assembly instructions, the wrench was too short and prevented him from screwing it into place properly. The bolt came loose, fell off, and got sucked into one of the LOX boost pumps, which jammed the pump and prevented its operation

I mean other maintenance failures were caused by people using the wrong tools or procedures so I‘m not sure I can blame the guy who did it wrong with the right tool.
Honestly, the first guy who used a different tool than specified should‘ve escalated the fact to get the records changed. But that needs an organizational structure that allows for this.

Surface gravity is a product of object density and object radius. Make something the mass of Earth but less dense and its radius goes up, surface gravity goes down.

This is why a neutron star with the mass of the Sun has a gravitational strength millions of times higher than the Sun's gravity at its surface. You're compressing an object that has 28 G at its surface with a radius of ~700,000 km and squishing it down into a sphere with a radius of no more than about 10 km. In fact neutron stars can mass as much as 140% of the Sun's mass. Think about how crazy it is that there are objects out there the size of Phobos with more mass than the entire Sun and everything orbiting it combined.

If you do don't forget to mention the new direction of small shuttles like the x-37b and dreamchaser at the end.

There aren't any good videos on nuclear saltwater rockets. I was looking for one last night so there's more than zero demand plus you could get zubrin meme views.

>>12212493
Actually if you could do a general meme-propulsion interview with Zubrin that'd be neat. NSWR, Dipole Drive, etc.

>>12212484
Fuck! I forgot to include something about dreamchaser into my Vulcan script.

If I do this I'm going to find a way to plug BWX technologies. Their stock needs to be higher. I'm honestly nowhere near well read on the subject, so I'd really need to do some research.

Why do people call him estronaut? Is it jealousy or just a groupthink meme?

>>12212512
My brother

>>12212531
he's literally the onions wojack meme given flesh and I just don't like watching his content
the transcripts of his videos (he calls them articles) are okay

>>12212531
He looks like a onions character and before the Starship days he acted like a basedboy too. He's been slowly evolving into more of a chad at least in terms of his long format videos (his tweets are still cringe a lot of the time but hey, he's still learning).

>>12212531
Easily meme-able, and it's not hard to see the similarities between him and the stereotypical basedboy, both in how he looks and acts.
He still probably knows more about rockets then most people in /sfg/ though

>>12212531

He, or the character he plays, gets very emotional over very stupid things.

>>12212531
I like him, it's just a nickname cause the guy acts funny sometimes.

>>12212558
He's got a fuck ton of patreons, and they do a lot of the research, but he is fairly knowledgable.

>>12212565
It worked though

How new are you?

I love everyday astronaut!

>>12212577
How new are you? No one will post everyday astronaut without typing a preamble disclaimer about how onions he is like they have a gun to their head

Soooo, we got the Amur, Project Retalt, Long March 8 and New Glenn rockets in development as Falcon 9 "copies". Are there any other companies/countries developing reusable rockets?

>>12212588
Everyday Astronaut presents easily digestible and usually well sourced information on spaceflight at a level accessible to most casual viewers who are willing to put in the time to watch an hour long explanation of why aerospikes are a meme. If you have a strong understanding of the history of rocketry he can come off as condescending, but that's because you aren't the target audience.

>>12212592
>Are there any other companies/countries developing reusable rockets?
Rocket Lab's Electron, ULA's Vulcan (kinda), and India's RLV-TD.

Welcome to the internet hate machine. Site culture dictates that we hate everything, and only point out the flaws of them.

>>12212592
To be fair New Glenn isn't a copy of F9, BO have their own design for reusability, but all the other concepts shown so far indeed just look like off-brand F9s

Who's gonna be the hundredth??

>>12212638
>TSTO with expendable second stage and first stage barge landing
The only significant difference I see with New Glenn is methane+h2 instead of keralox. Their process is sufficiently close that they ended up in (and lost) a patent dispute with SpaceX.

Next Mars launch window is between August and October 2022, can Musk get an unmanned Starship ready to launch there by then?

>>12212698
It doesn't just take a single unmanned Starship, but multiple with fast turn around infrastructure for refueling. I take that as an aspirational goal, not a realistic one.

>>12212711

I know.

So yes or no, doable?

>>12212716
anything's possible but they're not likely to even start work on stuff like deep space navigation and refueling until it reaches orbit so they'd only have a few months at best to get all that ready

>>12212716
I think it's fair to assume that they'll have the ships necessary if no major delays crop up. The fast-turn around and associated infrastructure is more questionable. I give it a hedged yes, CAN be done but probably won't.

>>12212607
Isn't the RLV more of an X-37b ripoff?

>>12212691
>keralox
Kerolox.
KEROsene, Liquid-OXygen.
Kerolox.

>>12212759
Yes, but if I'm reading about it correctly then it's a scaled down upper stage prototype for an eventual TSTO reusable rocket. Although that might mean that only the upper stage is reusable.

Knowing how shit india is at programming it wouldn't surprise me if the booster is lost.

So I was thinking about the fission torch SRB concept that someone suggested a few threads back, and decided to work out how well it would actually work as a drive. As a continuous fission reaction drive with the criticality in the nozzle, the closest analogue would be the Nuclear Salt Water Reactor design proposed by Zubrin.

LEU (20% U235) NSWR stats:
> Ve = 66,000 m/s
> Isp = 6728
> mass flow = 195 kg/s
> thrust = 12.9 MN

Solid rocket fuels have a much higher molar mass than water, but the uranium is unchanged, so I'll say the Ve/Isp for our fission torch rocket, should be about half. Given that SRBs typically have lots of mass flow, this is already looking like a legitimate torch drive. Then I decided to see what this looked like at Shuttle SRB scale.

Shuttle SRB:
> Ve = 260 m/s
> Isp = 3364
> mass flow = 4615 kg/s
> propellant mass = 500 tons
> dry mass = 90 tons

Plugging some numbers together, and we get...

HEAVEN'S LANCE "RHONGOMYNIAD" FISSION TORCH SOLID ROCKET
> Ve = 33,000 m/s
> Isp = 3124
> 127s burn time
> thrust = about 300 MN (!!!!!!)

That is enough thrust at a high enough Ve to return a 100 ton payload on an Earthward brachistochrone trajectory from LOW JUPITER ORBIT if you have a plasma magnet sail to brake, and /sfg/ basically came up with it on a whim. I am in AWE.

>>12212645

Done.

>>12212607

Thanks.

>>12212638

This is why I put copies in quotation because each of the them obviously differ from Falcon 9 in their own way.

RLV is a tech demo for the first stage, actually. The second stage is like ESA’s IXV with a fuel tank.
