MORE CRAB
>Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, expanding debris from massive star's death explosion, witnessed on planet Earth in 1054 AD. This brave new image offers a 21st century view of the Crab Nebula by presenting image data from across the electromagnetic spectrum as wavelengths of visible light. From space, Chandra (X-ray) XMM-Newton (ultraviolet), Hubble (visible), and Spitzer (infrared), data are in purple, blue, green, and yellow hues. From the ground, Very Large Array radio wavelength data is in shown in red. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation Taurus.

Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, expanding debris from the death explosion of a massive star. This intriguing false-color image combines data from space-based observatories, Chandra, Hubble, and Spitzer, to explore the debris cloud in X-rays (blue-white), optical (purple), and infrared (pink) light. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation Taurus.

Explanation: The symmetric, multi-legged appearance of the Southern Crab Nebula is certainly distinctive. About 7,000 light-years distant toward the southern sky constellation Centaurus, its glowing nested hourglass shapes are produced by the remarkable symbiotic binary star system at its center. The nebula's dramatic stellar duo consists of a hot white dwarf star and cool, pulsating red giant star shedding outer layers that fall onto the smaller, much hotter companion. Embedded in a disk of material, outbursts from the white dwarf cause an outflow of gas driven away both above and below the disk resulting in the bipolar hourglass shapes. The bright central shape is about half a light-year across. This new Hubble Space Telescope image celebrates the 29th anniversary of Hubble's launch on April 24, 1990 on board the Space Shuttle Discovery.

Why not just make bigger engines? This leads to a N1 tier plumbing nightmare

Explanation: The Crab Nebula is cataloged as M1, the first on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, an expanding cloud of debris from the explosion of a massive star. The violent birth of the Crab was witnessed by astronomers in the year 1054. Roughly 10 light-years across today, the nebula is still expanding at a rate of over 1,000 kilometers per second. Over the past decade, its expansion has been documented in this stunning time-lapse movie. In each year from 2008 to 2017, an image was produced with the same telescope and camera from a remote observatory in Austria. Combined in the time-lapse movie, the 10 images represent 32 hours of total integration time. The sharp, processed frames even reveal the dynamic energetic emission within the incredible expanding Crab. The Crab Nebula lies about 6,500 light-years away in the constellation Taurus.

Explanation: Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars. The overall blue glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, featured here, holds a complex tapestry of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. NGC 6357 spans about 400 light years and lies about 8,000 light years away toward the constellation of the Scorpion.

>>12703767

Give it to me straight, doc. We will never be able to get out of this filthy sol system, right? We were lucky enough to get the right materials and conditions for life, even better, SENTIENT life, but not that lucky as to get some ultra special atom that could allow us to truly discover the wonder of the space and time. We are doomed to live and die in this rock.
We are the fucking island in the middle of the vast ocean of space, away from the continents and other islands.

>>12703781
>NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars. It is also known as the Lobster Nebula[4][5] and the Madokami Nebula[6] by some fans of the Japanese anime Madoka Magica due to its resemblance to the main character from the anime, and a popular fan petition to rename it.

Unless FTL bullshit really is possible and if we somehow manage to figure it out within the next 50 (probably not) your only hope lies with life extension technology, be it via stem cell buggery and organ printing or cybernetic enhancement. If we can get that shit figured out (and I'd say we're more likely to have some basic means of life extension within the next 50 years) then we should feasibly be able to make it to the stars with basic ass laser sails or fusion rockets or whatever.
Diagnosis - hope to honest goodness that we get life extension soon or die as the angriest man in existence like I will

Induced hibernation is relatively easy to get working and could slow aging significantly during interstellar transit before awakening for capture using a plasma sail equipped NTP ship.
It would be faster with clever gravity assist and laser-particle beam accelerator stations
Hopefully micromachines get advanced enough to enhance our biological repair mechanisms and metabolism, we might even have forerunner-tier personal armor or irken paks
Seriously, with these, space travel would be routine

>>12703830
At this point everything depends on finding some hack around the rocket equation, whether through quantized inertia or just magsails. Solar wind velocity is ~0.001c so a sufficiently powerful plasma magnet sail that can get a sleeper ship up to that speed before hitting the heliopause would get you to the stars in a few thousand years.

Whole brain emulation doesn't need to be developed within your lifetime in order for you to be immortal. All that's needed is for a detailed enough scan of your brain to be taken that, maybe if combined with your genetic code, will be enough to emulate you when whole brain emulation is later invented. There are also other less sophisticated tricks that can be used to cheat death, like memory transfer to a clone body.

Oldspace companies never test until they are confident the test will actually work in order to save money, meanwhile SpaceX test their engines/rockets numerous times, sacrificing testing equipment in order to speed-up their development process.

>>12704460
In layman's terms, oldspace spends 5000 hours staring at simulations and papersheets to find flaws in their designs. Spacex spends 500 hours developing a prototype and blowing it up to do the same.

>>12704465
It's two different development philosophies, the SpaceX one carries a bit more risk but overall is proving to be the better one if done right.

>>12704452

>30+ meter heavy duty bearing
>the whole thing must rotate 180° in under a second
No, not really

>>12705145
I prefer the 4chan claw tower.

>>12705223
I don't think the rotation time of the video would be accurate to reality, they're saying that it would be using radar+LIDAR guidance so it should be able to see the trajectory of the Superheavy long before it reaches the pad. Even better would be to have the tower talk to Superheavy while it comes in, have both systems work together in tandem to minimize the amount that the bearings have to spin to catch the booster.
Obviously though it would be better to just have the booster be precise enough that it will never stray more than a meter or two from it's landing point so that you could catch it with a single ring.
I also really like that cable catch system some Anon on here proposed, that system could also change shape radically to catch a slightly off-center booster but without any giant ball bearings.

>>12703788
What, you think somewhere else has a better starting position?

>>12705269
>my ancestor :)

>>12705236
The main problem is that the booster will never come in straight and stable like in the video, there will always be dynamic deviations from imperfect trajectory, wind gusts, fuel sloshing, RCS firing and engines gimballing etc., so you can't just keep them in one position but must have them track the booster all the way to touchdown.
The next problem that follows is that small corrections in catching hole position require much larger and faster rotational movement of multi-ton rings which, combined with them being on top of a rather tall tower, presents quite an engineering problem in itself.

>>12705145
The way he words it makes it feel like some hyped up scam.
Still seems pretty good for the most part. My biggest concern is if it can actually handle having the weight of Superheavy coming down to the side and out of the way of the central line.

>>12703867
Add a multiplayer mode to KSP, with combat. Then let the best designs evolve.

>>12705370
True, that's why I like the cable-catch idea better, it can create a larger aperture and yet it can also close faster, is less likely to harm the rocket when it does catch it, and it would probably be much cheaper to produce, since essentially every part of it already exists at the scale which it would be used at.

>>12705390
KSP2 will have multiplayer if I remember correctly, and I'd imagine somebody will either port over BDArmory or create a new version for it as quickly as possible.

>>12705390

>>12703755
Elon says that SN10 has a 60% chance of sticking the landing. What do you guys think?

>>12705397
>>12705399
Oh sweet. Though, come to think of it, It'd also need an economic/resource constraint angle. Sort of a KSP/Eve Online hybrid. That'll get you the best ship designs within a decade (plus a thousand strong corps of, admittedly obese, experienced spaceship captains).

>>12705415
Is that increased probability cause of the fact they will light all three engines, or is it based on the two-engine relight?

>>12705392
The problem with cables I see is that they will choke the fuck out of the booster when it hangs all its 150+ tons on them, though this might be mitigated with some sort of stoppers preventing the cables from actually hugging the booster. Then there are towers that must handle the pulling forces and pulleys that won't jam with wires pulling at odd angles.

>>12705383
>The way he words it makes it feel like some hyped up scam.

Ah yes, I've been scammed by literal who CG artists many times. I transfer them millions of dollars and they can't build it.

>>12705421
Two engine relight still probably no one knows. SN8 had perfect engines and SN9 fixed the header tank issue so SN10 just needs good engines to be fine

>>12703781
>>12703794
Would like to see these two images aligned, can't tell what features are what

>>12705424
Anon's diagram had some sort of large gripping pads between the rocket and the cables themselves, and it would still settle its weight on the gridfin roots, which have to carry the rocket's weight in any catching system.

>>12705436
Elon said they could relight 3 for SN10

Starship will look like this?

>>12705446
How do we even build bases like that? In situ concrete?

what do you do with garbage on mars?

they're going to have to have their landing algorithms pretty much perfect

>>12705477
Dig a hole a throw it into it then bury it or just burn it if you can.

>>12705482
I can't believe they plan to have humans on that thing. Remember how many times Falcon 9 RUDed on the droneship before they perfected the landing?

>>12705145
neat

>>12704457
that's roland deschain isn't it?

>>12705494
You mean while landing it? I thought that was fake, is it actually not?

>>12705444
The pulling forces on the cables can be like an order of magnitude larger that the weight of the booster depending on their sag angle (similar to centrifugal forces on helicopter blades) and they will propagate on to squeeze the booster like a noose so it will have to be reinforced for quite a bit to withstand those, pads or not. By adding stoppers on the cables you can make them stop from tightening all the way on the booster, rather forming a square-shaped hole for the booster to loosely fit in and just hang on the gridfins without any of the cable forces transferred to it. This still doesn't address the issue of towers handling the 1000+ ton forces from cables pulling them inwards at the top.

>>12705482
I have a feeling New Glenn is pretty expensive to build. There’s a reason Blue capitalizes on “Oh well it can fly 25 times.” That’s such an arbitrary number that I think New Glenn actually has to fly over a dozen times to break even

>>12705509
Yeah I said it a while ago but I'll say it again: my gut tells me New Glenn will suck at being refurbishable. No matter how good they get at landing, I bet even at their most efficient and optimized pace it will still take >6months to get a core flying again, and will cost just slightly less than just building a new core from scratch.

>>12705269

>>12705509
Why does New Glenn look like a bullet vibrator compared to the rockets surrounding it?

Booster could land in a sort of "pit" with flame diverters in the ground (or constructed on an oil platform, which can be tens of thousands of tons in mass). In this way you can shorten the actual size of the towers to make them stouter, and by having multiple towers you can spread out the forces applied to them. Oil rigs are actually especially good for this, as they are enormously massive structures which can hold almost an arbitrary amount of weight. Just the structure of something like Troll A weighs more than half a million tons and is almost half a kilometer tall, of which about 170m sticks out above the waterline.
While the platforms SpaceX have currently bought for expedience sake are nowhere near as impressive, I don't think in the long term (2024+ to 2034+) they'll have much of an issue with the catcher structure, although personally I seriously wonder why Superheavy can't simply be made 10% taller to account for maybe 20 more tons of some very stout legs, it's dry mass is already almost a completely negligible fraction of it's wet mass.

This is a premise that growing up with television has largely created. Men have been living very isolated lives in remote villages, as shepards in the mountains, lighthouses, ships and many other examples for thousands of years.

To be fair, New Glenn will be able to hover and if you watched New Shepherd, they are not afraid to just inefficiently come to a full stop 10 meters high and do the last leg very carefully.

Well, if an engine say consumes 250kg of fuel and oxidizer every second, and you have four engines, it would consume a whole extra ton for every extra second you want it to burn.
If your rocket has to hover for say an extra five seconds of deceleration, that's five tons more you need to dedicate to reaction mass that you can't dedicate to payload. A BE-4 is about a third as powerful as the F1, which burned almost 6 tons of propellant a second, for simplicity's sake lets say BE4 burns a third as much mass, two tons a second.
I assume that like Falcon or Superheavy or Starship it will only come down on the central engine, so if it hovers for 5-6 seconds prior to landing as New Shepard does it will consume 12 tons of propellant in that time, costing it approximately the same amount in cargo mass.

Why is a loli narrating?

>>12705313
Why would they not? We know some species of animals and plants had better conditions than others, and while all went through natural selection -regardless of their habitats- it is a fact that having better resources increases the chances at surviving.
Now, we can see an even more clear proof of this on the early human societies, where having easier access to materials such as metals, wood, farmlands, etc.. meant having an advantage compared to those who don't.
Not all is necessary good tho, having a more hostile environment could also give an incentive to improve their own conditions, which led to inventions and revolutionary methods or techniques that would also give an advantage. Nevertheless without an appropriate amount of quality resources, no matter how much aspiration or invention a society has, they would ultimate be held back.
Now considering again my words of; "we are the island on the vast ocean of the universe away from the continents and other islands", it would make sense than there is very big chance that some alien society has a more hostile environment that forced em to evolve past our point, and smaller but not negligible chances that there is an alien society with not only a hostile environment but also a greater amount of resources and perhaps even exotic resources that may not be present in most of the galaxy or even universe.

>>12705935

fuck me, that would be quite shit. I suppose that would be what you get for not working on your avionics for years, assuming they use the same landing profile.

FACT: there will never be "space warfare" due to Kessler syndrome, orbital mechanics, and the inefficiency of rocket engines compared to jet or even propeller engines. At best you may see the construction of EMPs to disable enemy satellite networks.

>>12705989
But how easy would it be to travel between the different planets? The entire system across is around a third the distance of the shortest distance between Earth and Mars. The light lag would be like one minute even to the opposite end and there'd be transfer windows nonstop.

>>12706017
Yeah, a hoverslam maneuver, once properly programmed, only takes a second or two, so you could recoup most of that loss. I mean obviously even vehicles like Starship and Falcon 9 are still sacrificing significant payload capability for the ability to retropropel in orbit and then land, especially true for the low volume Falcon 9 who's comparatively high dry mass ratio means that it could carry closer to twice it's reusable payload if it just spent all of it's propellant in acceleration, but a hover landing exacerbates that problem unnecessarily.
Because of that New Glenn is a strictly inferior design to Falcon Heavy, which wastes less propellant on it's landing and has a greater maximum payload capability. It's not even in the same weight class as Starship/Superheavy, we'll have to wait for New Armstrong for a direct comparison.

I believe that by constructing a satellite array that can shield the planet from the solar winds and the detonation of a few hundred nukes on the poles should be enough to get an atmosphere going, whether the radiation on the soil can be dealt with, that can wait after we get an atmosphere and liquid water.

hell, if they dont find a fix for the moondust getting in to everything even a moonbase would be impossible, the astronauts who visited the moon were already getting irritated airways eyes from only being there few days.

Make get involved in some project or something, where you're depended to deliver on like a web page or a link or something, then embed a link into it somewhere.

venus nightside is basically the same temperature as the day side. i know thats an extreme example but the temperature differences wouldn't be that bad. you could probably not live on the extreme sides but the climate overall wouldn't collapse
>>12706383
i never claimed there wouldn't be differences. learn how to read

>>12706392
9000 hours of cfd then realize it doesn't work

>>12706396
That's a good idea. I got like 30 (you)s from the fake NASA twitter page.

Janny Magnus, I have a question concerning your friend and co-poster, the darling of Reddit, Gaius Anonymus Faegot.
Why does his head remain empty? Why does he not go home? His illegal shitposting is over. /sfg/ is long since on her knees. Why does he keep us brave posters from our discussions and memes?

For an entire week he has gorged himself like a faggot on (you)'s of bait and thereby made himself monstrously rich.
WHY?
Why does the ply the mob with earlythreads and furfaggotry and gaudy /pol/ posts?
Why has he given (you)'s to every reprobate fool in this thread?
WHY?
I tell you why he does those things. He wants to buy himself a 4chan pass. He wants to destroy the /sfg/ general and rule /sci/ as a bloody Mod! That's why!

Therefore, I move that these faggot's posts in this thread be terminated immediately, that their IPs be banned, and for them to be recalled to /qa/ to answer charges of illegal shitposting, bait, faggotry and treason!

Listen to >>12706392
Maybe try linking to Judy Hopps or Maid Marian.

Is it possible to solve the magnetosphere issue on Mars?

>>12706413
Yes, a small but very intense magnet of only a few dozen tons could not only lend Mars a magnetosphere, but lend it one several times as powerful as the one which naturally surrounds Earth.

>>12706404
That's not Fay, or Miyu so you're in the wrong here

Now everyone, we're gonna build our own spaceship. Now, how to we build the hull?

SpaceX: BUSTED!!
Its over pack your bags we are not going anywhere....

>>12706419
Is Elon planning to build one? If you could do that, colonizing mars becomes 1000x easier.

>>12706425
I’ve considered making a space YouTube channel with Clickbait shit about SpaceX in the past. Is it a good idea?

>>12706425
It's over boys..

>>12706425
Based thundercuck!

>>12706425
how the fuck is he gonna justify this one

>>12706430
if you want easy money, sure.

>>12706400
>this planet isn't uninhabitable, it's differently habitable
ok

>>12703755
I just got dumped today bro’s. Anyone got any good spaceflight shit to read about/watch?

>>12706042
Didn't the euros try to make flyback boosters and gave up?
Why didn't their flyback boosters work?

>>12706419
i remember a thread where some anons actually did the numbers on that, it would not be a "small magnet" but small moon sized.
require fusion levels of energy to sustain it, and the sun would constantly be pushing it away so you need some strong force to keep it in place.
The conclusion was that it would be easier to build a oneil cylinder then this "small magnet"

>>12706425
What does he say in this one?

>>12706445
Soyuz will never leave you anon <3

ESA has some stuff going on but only on paper so far, frog ARIANA is too powerfull and will cockblock reusable rockets.

Anyone got a tl;dw?

>>12706461
Would have guessed he spent the first 10 fanning his own balls, as per usual.

>>12706461
how are there this many unironic boeing fans

wtf, do thunderfags just suck thunderf00t's cock and not actually think for themselves at all

how can you be this stupid

>>12706469
>>12706481
>>12706491
3 times and you're just playing with yourself anon, calm down

this is oldspace's fanbase

>>12706469
Applying this logic, what is the same equivalent now considering launches are cheaper?

>>12706450
That's simply incorrect, the only actual serious proposition for such a device I've ever seen had it approximately the size of a house, 20-30 tons in mass, 50 tons overall including a 2.5-3MWe/5-6MWth atomic reactor and attendant shielding and heat management.
You're not trying to build a magnet with an origin point inside of the planet itself at it's center of mass, you're building a magnet that sits far outside of the planet and essentially cloaks it in the magnetotail of the generator.
On top of this it turns out that Mars is not as radioactive as was once believed, and that it's atmosphere actually does provide some significant protection, you could probably halve this field generator and still achieve the desired effect. It should go without saying though that this is essentially nothing more than a luxury anyways because it will take twenty years of EVAs to get a significantly dangerous (5% increased cancer rate) dose of radiation on Mars to begin with. So you'd have to be EVAing 12 hour days for 40 years to have a 5% increased risk above normal of developing cancer.

>>12706425
About halfway through
>Hyperloop has struggled therefore SpaceX should stuggle
>claims that the Shuttle's 7 person capacity somewhat justifies its cost while ignoring that the Falcon 9 could do the same but faster cheaper and safer
>maintenance is a killer for reusing rockets because techniques can't improve for some reason
>points out how SpaceX fell short of its high goals while ignoring how much it improved compared to other companies
>muh reuse halves payload whats cost reduction
>graphs and plots to show how SpaceX is failing compared to a made up ideal with little to no math shown

>>12706507
so more bullshit from a faggot who literally doesn't even understand how orbital mechanics work yet. how can people trust this nigger

>>12706500
>rockets explode when they hit the dome
>>12706507
When will someone just beat this fag?

>>12706481
>most flights for several years now using reused boosters
>up to 7 flights for a single booster
>"SpaceX flatly acknowledge that they don't use reusable rockets"
these people think they're le epic intellectuals while they flat out deny reality

>>12706511
its sad really. flat earthers are literally siding with oldspace over spacex

>>12706305
Armored suits and slap patches, buddy.
And why are your tunnels so close to vacuum?
60% death rate, tops.

>>12706514
Unfortunately this is the ABSOLUTE state of most """intellectuals""", most people are just unwilling to see it. Most of them will rather accept blindly the assertions of their peers in an enclosed academic circlejerk which is almost entirely disconnected from practical reality rather than acknowledge things which are literally going on directly infront of their own eyes.
Darwin had to put up with this same exact shit and for the same exact reason.

>>12706502
If we're going by internal costs, somewhere around silver for F9

>>12706441
the weather and climate would be different and there would be no day night cycle. the planet would still be habitable in every definition of the word.

>>12706481
Looks like we need a SpaceX edit of this
>Elon is going to take us to Mars!
>Um actually we should focus on problems here and Mars is a fantasy anyway
>Elon is going to take us to Mars!

>>12706507
thx anon
For everyone else this is the key to the tent:
>>You don’t have how much it costs spacex just the price for the customers

>>12706507
The other half
>actually shows some math and concludes that SpaceX will break even at 6 flights
>overlooks that boosters are getting close to that mark
>points out how SpaceX isn't reducing their price per launch because companies can't charge higher for profit or savings
>pulls a number from an oldspace CEO claiming that 10 flights are needed for breaking even
>ignores that most oldspace companies aren't even seriously trying for reuse and must come up with a justification to not look bad
>claims that Shotwell is lying because her given numbers don't match his made up ones
>muh E2E is impractical and delusional
>SpaceX isn't making any significant savings in getting to orbit apart from the times that it did
>price dumping claim with no supporting evidence
>SpaceX charching extra per launch with the government to cover costs of building new and different infrastructure is proof of price dumping apparently
And I stopped watching there. Too much stupid

>>12706548
Tf00t actually fell for that bullshit cope from the CEO of arianespace?
What an idiot.

>>12706526
The debate ultimately settles on whether the 'twilight' zone would persist as a habitable zone within an otherwise desolate planet, other than you I have never seen anyone suggest that the hemispheres would simply 'balance out' and lead to an equally habitable planet as the earth

>>12706553
>Tf00t actually fell for that bullshit cope from the CEO of arianespace?
No. He got it from Tory Bruno

>>12706562
When did tory say that?

>>12706553
He's not just an idiot, he's also actively malicious. These people are all TSLAQ people, not people who have any interest or know anything about aerospace.

>>12706548
>price dumping claim with no supporting evidence
he has a future at roscosmos

>>12706548
>>actually shows some math and concludes that SpaceX will break even at 6 flights
>>overlooks that boosters are getting close to that mark
Hasn't one landed eight times already? Don't SpaceX say themselves they break even on flight two or three?
