I remember this mod back from 2013 or so. Before the Crew Dragon was even finalized.

I remember landing like five of those big-ass ships on Duna and being proud of my 100-kerbal colony. Fun times fun times.

Sorry OP, rockets don't work in space. When you use logic, reason, and actual real science, you realize rockets only work (definition: propel themselves forward) inside an atmosphere. This means they don't work in space. Sorry to shatter any illusions you may've had.

The plain truth is they don't and can't work in a real vacuum.

So will a rocket which "works in space" (propels the craft forward) ever be invented? No. No such technology can ever exist. Any claims of such tech existing is a fraud and a lie. You want to believe in a fraud and a lie?

>inb4 you parrot "newtons 3rd law!" like an NPC without any thought involved
That law isn't in dispute here. Quoting it to "prove" rockets "work in space" shows you don't grasp the fundamental problem here. The 3rd law is 100% correct. When asteroids floating in the vacuum of space crashes into each other, the 3rd law applies. Likewise, the law applies to objects interacting on the ground on Earth, underwater, and in the sky. The 3rd law is real, but it doesn't "do" anything for a rocket engine fired in a perfect vacuum.

You see, the atmosphere gets thinner at higher elevation until it disappears completely (out in space). That's the issue is here! And you can't get around that issue. Parroting "newtons's 3rd law!" or throwing math equations around, doesn't magically make the issue go away. That's just you avoiding to deal with reality. Man up and stop avoiding reality.

If you're currently under the "rockets work in space! xd!" spell they cast on you through the entertainment industry and educational system (the indoctrination system), and you want to break free from that spell and shatter the illusion - then see these two educational videos (they play inside your browser):

First vid: https://files.catbox.moe/dl9ldw.webm
Second (also important): https://files.catbox.moe/so2rrt.mp4

Once you know that stuff, then you know beyond any doubt rocket technology will never be viable outside of Earth.

>>11689273
And OP, if you have a short attention span and you therefore have difficulty following a scientific presentation in video format, here is an illustration which can assist you in understanding that rockets indeed do not work in space. You're welcome. You're now ready to take your first steps towards embracing the real world.

>>11689273
Fuck off, I'd actually like to keep this one legitimate. Even /pol/tards and jews kvetching is better than this.

>>11689278
Just report, ignore, and bask in the glory of space flight.

I didn't announce a report, just suggesting something that contributes to the health and posting quality of the community.

WITH A BOX OF SCRAPS

>>11689287
You could try to ignore the truth, but you can't. You become upset and angry when the truth is pointed out to you. You cannot resist attacking the truth, the physics and attacking the messenger. And it doesn't work. In the end, the truth remains and the physical laws of the universe are what they are.

>>11689323
Same. I wonder how much coverage SpaceX will give for the mission.

>>11689330
Just like NASA is a fictional and Hollywoodized theme park presentation, so is 2001 A Space Odyssey is a fictional movie. Stop believing in fiction.

first for squashed chinks

>>11689354
you obviously don't live on the east coast, you can see them burning up and out from most of GA, SC, and parts of NC

>>11689332
Why does the truth about rocket propulsion upset you so much?

>>11689354
The holobunga is a fictional and Hollywoodized theme park presentation, not NASA.

>>11689354
Dude I live by Vandenberg and I'm telling you right now either the government is spending billions just to convince people space is real...for some reason... or maybe it is possible idk man I mean the physics work.

>>11689357
Ignore him. He's not worth your time. If the last 50 years of space flight hasn't convinced him, then someone on a Bhutanese basket weaving forum won't either. Instead, focus on the amazing things in space flight (especially ones that are coming up) and leave him to whine to himself.

>>11689376
I just wanted to talk about that time I watched SpaceX launch to the ISS from my parent's beach house

>>11689357
Rockets work in Earth's atmosphere. Their ability to propel diminishes exponentially, however, as they gain in altitude and the atmosphere gets thinner. Until eventually they can't propel at all, and fall down. This is unavoidable and is something which is entirely to be expected. You shouldn't be surprised at what you're seeing.

>>11689315
The quality on these is really going up, can't wait till we see the ones with the weldbot and planisher

>>11689383
Tell us about it. Which mission was it?

Going back to the OP, do you think a space ferry like pic related could actually be built and launched?

thicc

>>11689374
NASA literally is Jew-speak and means to be deceived.

>>11689375
The physics show that rockets don't work in space.

>>11689261
Hi everyone I'd like you all to meet my big beautiful girl ICS Endurance. She's powered by a fusion engine and can take 100 Kerbals to Laythe and Back in under three years.

In all seriousness though fusion engines are OP in real life too. How close are we to developing them? Everyone says we're close, but still 20 to 50 years away.

>>11689404
Except the jew-enese is pronounced na-SHA, JIDF shill. I've got enough leech blood to translate and see through your glowniggery.

>>11689404
gift means to poison, presents are just a murder conspiracy!!

Alright, how do we build an engine like this capable of lifting a decent sized payload
This could just be a prototype engine

>>11689404
Stop shitting up this thread man I just wanna look at rockets.

If you really don't believe space exists wait a few years then buy a ticket.

>another view of Endurance over Laythe. Only took a year to reach Jool

>>11689404
trombones are a musical conspiracy for paper clip compaines

>>11689418
are they solar sails or PV?

>>11689399
It could work, but it would need to have a propulsion system that's better than chemical or else you might as well use an additional upper stage for simplicity of mission architecture. NASA did some studies post-Apollo pre-Shuttle and came up with concepts for nuclear tugs.

>>11689426
Those are heat radiators. Endurance is powered by a run of the mill fission reactor but uses a fusion engine. This gets things really hot.

>Pic related has huge heat radiators. Although Avatar the movie sucked, they got the spacecraft right

>>11689407
Looks neat. What mods are you using?

>>11689417
Depends on what you want to do with those engines. It might be barely feasible to get something sent to orbit using those engines depending on the powerhead. Suborbital is very feasible so long as the design of the rest of the rocket isn't messed up.

>>11689437
Can confirm. I'm using nuclear engines and cheetah engines, and its thrust is pathetic.

>>11689439
neat

>>11689443
KSP Interstellar Extended

Here's a NASA report about using a fusion engine to send a lander to Pluto in three years. Crazy stuff. Too bad fusion is underfunded.

For the uncensored thread: https://archive.is/dLe9U

Static fire soon!! https://youtu.be/povBCjZDYbQ

>>11689439
what's the deal with radiators? Surely if you're producing so much heat you have to radiate some off, you would want to use it in some kind of energy-producing process instead of just letting it dissipate. It feels like a waste when it's so expensive to get energy up there in the first place.

>>11689443
N2O oxidizer and propane fuel so the tanks don’t have to be super heavy and that they’ll stay liquid at working temperatures as long as they’re under pressure which both are pretty low

>>11689456
That heat could even be used to make a conventional generator to store energy.

>>11689456
>Surely if you're producing so much heat you have to radiate some off, you would want to use it in some kind of energy-producing process instead of just letting it dissipate.
The issue with this is that such energy-producing processes don't use heat directly. Instead, they use a heat gradient. They need a place of higher temperature and a place of lower temperature to generate energy. So replacing the radiators with those energy-producing processes would only work until heat is evenly distributed across the ship, and then the ship suffers from a heat failure because it can't remove the heat from itself.

>>11689456
You need an energy sink to actually do work since energy flows from high to low
Using it to maintain cabin heat and to power generators is certainly a good idea but they must eventually sink their heat somewhere

Static Fire lads.

BRAAAAP

Was that it? Or was it just a preburner test?

SN4 Static Fired

yo this nigga leakin

Scared for that engine now.

you all doubted me

it's fine, remember this happened

methane burns at like 2000°C but it doesn't transmit heat that well

uhh guys

>>11689506
She's okay its just a venting thing hoppy did it too

still burning

>>11689517
isnt that just flare reflection?

I'm so glad there's an English autist to talk nonstop all over the lab stream now.

Is it just the gas igniting on the scorch mark?

stillll burning

All the wires near the thrust puck and stuff are probably fried to shit. No hop for SN4 I guess.

Yeah, considering the explosive RUDs we've had before, hopefully this is just a clean up the scorch marks and make sure no damaged wiring and continue. Much better than before.

yall got any costume flags for me?

Would a spider-legged robot be a viable way to crawl across very low-g bodies like asteroids?

>>11689687
yes

realistically speaking, how far back does the fire put the hop?

>>11689687
no

>>11689687
maybe

>>11689735
Probably a week or two. I doubt we are seeing the hop until fall personally, but I'm always pessimistic about these things

>>11689735
2 days-a week unless they push it to after dm-2 for publicity reasons
it looks like a pipe on the outside blew so the main structure is fine

>>11689687
if you go slow and the legs dig in enough with each step

>>11689721
I had the idea after I tried to land a rover on Gilly in KSP. The gravity is so horribly weak that there’s barely any traction, so it’d go sailing off every time it tried to move with its wheels. The load-bearing ability of spider legs would be greatly strengthened in that environment, and it’d be able to creep around without relying on wheels, so I’d imagine it’s be a pretty reliable way to maneuver around the surface. Could stick a thruster at the bottom of the chassis to jump off cliffs and decelerate.

>>11689786
Don't fuck with no wheels or robot legs on Gilly, just use RCS thrusters.

That sounds fucking awesome. I was picturing an astronaut in an EVA suit sitting on top of the spider in a seat, maybe even with a controllable robotic arm or two. Laser cannon sold separately

>>11689902
Way too close to the launch date for this to happen now.

Either he's quit because he has concerns over crew dragon or ((someones)) forced him out..

>>11690068
If he has valid concerns about Crew Dragon he could simply have brought them up at the last minute assessment and potentially have called for a delay. If his argument was persuasive enough even the most hardcore spacex people would be okay with some more time. We all really REALLY want this launch to go smoothly.

> took such a risk earlier in the year because I judged it necessary to fulfill our mission. Now, over the balance of time, it is clear that I made a mistake in that choice for which I alone must bear the consequences. And therefore, it is with a very, very heavy heart that I write to you today to let you know that I have resigned from NASA effective May 18th, 2020.
what the FUCK Loverro?

I am skeptical of SpaceX and I think Musk is a dickhead but I've just realised that their marketing is genius. They made space popular not just because of their successes but because of their failures. I realised this after seeing everyone cheer every time one of their rockets explode. They're a "private" company so no-one gives a shit if their rocket blows up and it gets them more views on Youtube anyway. Compare this to the Soviets who went to great lengths to hide all their failures and NASA who moves glacially slow because they can't afford to fail in the eyes of the taxpayer. I'm working on an unrelated project right now and the comments don't seem to care whether it succeeds or fails, they just want to see speed/loud bangs/destruction. I think I may take a leaf out of Musk's book and capitalise on this by doing all my testing live even if I know it's probably going to go wrong.

>>11690001
I'd believe it. We can't allow sending a homunculus into space and let it evolve into a perfect being.

>Had heard rumors (and just that) of friction during the Human Landing System selections.
says Berger.

While the agency officially announced Loverro's departure as a resignation, two officials with knowlege told POLITICO that he was pushed out over disagreements with Bridenstine.

Even when SpaceX fails they play it off lightheartedly and then reveal out of nowhere that they’re already two steps ahead. An added benefit is that they appeal to the “common man” by telling everyone that we can go to Mars for half a million dollars.

Most of all Elon is a great figurehead. Debate whether or not he actually designs shit or not, but people love him. Once corona ends everyone’s gonna forget about him getting pissy on Twitter.

But as someone said earlier they’re very transparent, which also means we get to see their successes in real time.

someone convince me it isn't related to Boeing loosing the cargo AND crew lunar contract

>>11690150
http://www.spaceref.com/news/viewsr.html?pid=53668
The wording of the letter is quite hedged. He refers to HLS and "the plans we have placed in motion to fulfill our mission" in positive terms and says that he chose to leave over "personal actions", yet any major decisions surely would've required more opinions than just his.
Surely Berger won't sleep until he finds out the truth, or at least a warped perspective of it.

>>11690186
Loverro's acting replacement is the guy who awarded lunar cargo to SpaceX, though we'll have to see if he's replaced by someone more oldspace-friendly.

>>11690186
Politicians&nasa&mainstream media shitting on boeing at the same time at the moment is a key sign that boeing has stopped or has been late on its bribes, probably because of massive losses recently like the MAX fuck up&corona fucking over the industry.

>>11690186
Unironically cannot since if it truly isn't about crew dragon and him an Jim have been 'butting heads' at the beginning of the year it has to be about the crew lunar contract but I am willing to bet considering the amount of SLS retweets he does and being a boomer he wanted Boeing to be a 'backup' no matter the cost and Bridenstine probably told him/convinced him to exclude them because of the current track record.

>>11690146
oh fuck me i hate this gay ass planet

>>11690212
>Everyone thinks Loverro leaving is bad for SpaceX
>It is because Boeing paid him to put a bomb on D2 on his way out
Sheeit

>>11690227
They wouldn't have paid him, it probably was just a last 'fuck you' because he thinks Boeing are still trustworthy contractors and would provide the backup NASA might need if the other 3 fall through.

>>11689902
>https://twitter.com/SciGuySpace/status/1262827696763125761

Do any of you faggots even know who the guy taking over the spot is?
Its Ken Bowersox.
Last year in July, he was appointed this same spot when the last guy left, its temporary while NASA finds someone else.

daily reminder that nuclear propulsion rockets BTFO soiboi fuel rockets and that weve been robbed of our mars colony future

>>11690123
>>11690151
It has nothing to do with watching failures and everything to do with speed. Spacex will try and fail 10s of times before NASA even attempts something and by then spacex already fixed the issue. Look at how much spacex has gotten done, the falcoon 9 already surpassed the amount of launches the atlas 5 has and the atlas 5 has been around for a decade longer. Spacex is bringing manned launches back to the United States next week and they have a clear, popular goal. NASA has had 60 YEARS to do something more exciting and large but they just eat money and scrap projects. The mars rovers were incredibly impressive but they couldn't even keep them exciting. Spacex is the reason other companies are pushing for space flight, its the reason NASA has the Artemis program and it is the reason we have any hope of manned missions outside of the ISS.

Doomers will be weeded out in selection due to their weak mentalities, so you're almost right

Taking a 'side' in fuel is fucking stupid. There will be a wide range of tasks suited to different fuel types. Chemical will be the best way to launch until the end of time, while nuclear will have its place in long distance travel.

My professional opinion is, it needs to be more on fire next time.

>>11690355
Exactly and they're transparent about it, compare that to blue origin where its so secret that even the ones who are very into spaceflight can't be overly excited. Spacex on the other hand is showing each test and doing it frequently enough to follow easily. You are right about thw figurehead part too, Elon is excited about his mission, tweets updates and has a genious millionaire persona. His other companies complement his spacex mission and get people excited for the future. We haven't seen that in generations.

With the current state of the world you would not even be allowed to make a nuclear lightbulb rocket to take of from earth.
NTR is for when we already have a permenant pressence on the moon and we have had several missions to mars.

Before that I got some shit where I could only place maneuver nodes in the Kerbin system and any time I sent something beyond minmus I could only control it manually.

>>11690405
Exactly and they're transparent about it, compare that to blue origin where its so secret that even the ones who are very into spaceflight can't be overly excited. Spacex on the other hand is showing each test and doing it frequently enough to follow easily. You are right about thw figurehead part too, Elon is excited about his mission, tweets updates and has a genious millionaire persona. His other companies complement his spacex mission and get people excited for the future. We haven't seen that in generations.

I took such a risk earlier in the year because I judged it necessary to fulfill our mission.

And therefore, it is with a very, very heavy heart that I write to you today to let you know that I have resigned from NASA effective May 18th, 2020. I want to be clear that the fact that I am taking this step has nothing to do with your performance as an organization nor with the plans we have placed in motion to fulfill our mission. If anything, your performance and those plans make everything we have worked for over the past six months more attainable and more certain than ever before.

Was it dependence on Boeing?

>>11690540
Hopefully, fuck politics.

This is what happens when you gave money to Starship and not Boing.
We all went wtf when that one was announced, it has to be the reason.

>>11690576
Starship only got 100m. National team got 500M and the other one got 300m something.

>>11690581
there's a second selection phase—less money is better

>>11690581
Yeah, but I'm pretty sure Boing was intended to take that third spot. It's not a matter of how money they received. It's a matter of form.
Remember, there was a lot of pushing internally for that particular lander because NASA would end up with full ownership and it would naturally be comfortable old cost plus.

>>11690630
>Don't even talk about finished price and spec.
The point is the estimated cost is half the price of the others estimated cost. Also the specs may not be accurate but as you say its a much larger ship. Any mission would benefit from having more space/equipment.

>>11690485
Yes. If Boeing hands in an obviously threadbare proposal on a supposedly fast-moving project, it is the duty of the one procurring, that everything grinds to a halt, so he can give constructive feedback, so Boeing can resubmit a bare-minimum proposal that NASA can then pick over more viable options that won‘t be 10 years delayed for tripple the budget.

When you thoroughly trounces the competition on the fundamentals so hard that even allowing for multiple orders of magnitude of slop still beats them out handily 'half the price' is conservative, if anything. Also none of the competition is any more complete, you just don't see their unfinished prototypes on a livestream everyday.

It's going to be alright. There's so much to look forward to in the future.

Can anyone think of a single good reason to retire before such an important launch? I can't, except there being safety concerns with the vehicle. Anything else and he would just wait until after the launch. He was even on the go-no go poll. This is seriously worrying.

He's a bit shy

Everyone here says that terraforming mars is a meme, but would there be enough gases in the poles and in the ground to at least make the low-lying areas thick enough we wouldn't need pressure suits? Sulfur Hexafluoride looks interesting. Very powerful greenhouse gas and non-toxic to humans. And it's dense so it would settle in low lying areas.

What we really need to do is take some of the CO2 from Venus' atmosphere and transfer it to Mars to thicken that shit out. Then bombard that bitch with thousands of comets from the kuiper belt to build up water and oxygen. Melting the poles with nukes would be the final step. The real problem after all that is creating an artificial magnetosphere to protect your new atmosphere. IIRC it would take an electromagnet made of more copper than humanity has ever mined in it's entire existence.

>>11689439
>they got the spacecraft right

I dunno, the engine placement in a puller config looks like it would be blasting itself with it's own exhaust.
Also the big mirror thing is supposedly a photon sail according to the wiki. Seems like it would need a beefier mounting point if it's going to be pushing/pulling the entire ship.

>>11691221
The Dynetics lander is cute

>>11691210
This makes no sense. The magnetosphere is hardly an issue, something like a hundred kilos are lost a minute. A single gas emitter, nuke or ice melter could take care of this easily without any gargantuan effort. Bombarding with comets might be a far away type thing but melting the caps should be a priority. Also water could react with volatiles in the surface and cause more outgassing. Maybe a more near term effort could be large mirrors or SF6 synthesizers. A blue world fantasy is probably quite far off, but making some lowlying areas with active terraforming efforts more hospitable seems to be quite reasonable.

>>11691165
SN5 is on the left of pic related. Both are being built

>>11691242
Looks like a bug

>>11691197
I know.
>>11691254
a cute bug, with big rabbit ears

>>11691245
100 kilos a minute might not seem like much, but that adds up over time. Why would you put in the work to create even a tenuous atmosphere on Mars if it was going to be gone in a few centuries? Not only that, but having an atmosphere on Mars is pointless if the humans living in it are constantly exposed to high levels of solar radiation.

All of this is academic though because orbital habitats are far more economical than planetary colonization/terraforming will ever be. Why waste time and energy trying to change a dead world when you could just build a paradise in space for the same amount of effort/resources?

>>11691254

4663204, that's the number of years it would take the solar wind to remove the mass equivalent to one medium sized comet impact.

4650, the number of years for the solar wind to remove one year of india's emissions of just CO2 from the Martian atmosphere. Solar wind is a meme.

>>11691259

>>11691259
Also, the whole orbital thing is kind of a dead end. Yachts are 'pointless', but people still buy them. Terraforming would be a great program for martians to undertake, have something like the eagle scouts work for it. Even if it was completely pointless (which is obviously untrue) it would still be a great monument to 'human innovation'.

https://physicsworld.com/a/magnetic-shield-could-protect-spacecraft/

Also on the solar wind stuff, no expert on magnets or radiation, but could something like this work to protect a colony? The power requirements might be an issue, and it won't be perfect, but it could drastically reduce the radiation exposure while going outside. I've also heard of a big magnet at L1 Mars-Sun. Dunno how feasible that is, if I had to guess, not very. But the point isn't a habitable mars now, it's one in the future. Plus it could make decompression events less severe.

you won't put even near as much atmosphere on mars as 100 kilos per minute.
which means you absolutely have to minimise atmospheric losses.

>>11691370
Cover Mars in a dome

>>11691370
If you can't exceed 100 kilos a minute, you won't be terraforming Mars. That's a tiny amount of output, you have no sense of scale.

>>11691370
? Just the caps have enough CO2 that melting them would take the solar wind 2797 years to cancel out. Solar wind is only meaningful on really large timelines. Any early progress is just tech demonstrators for real stuff that is only really gonna be feasible 75+ years from now.

So what's the scoop on Relativity Space? A senior SpaceX exec just jumped ship to them. These things are pretty sick looking-imagine getting a few of these in space and building a fleet of rockets to carry home harvested resources,or to print even more 3d printers

>>11691811
They're not reusable though. I think Rocketlab realized that in the long run they'd lose to SpaceX, so now they want to reuse their first stages.

Ten years ago Relativity would have been king.

>>11691816
>I think Rocketlab realized that in the long run they'd lose to SpaceX, so now they want to reuse their first stages.
Having multiple companies with reusable first stages if not fully reusable rockets is a huge milestone for space. I hope Cubesats can get under $50k/U with reusable smallsat launchers.

>>11691816
I don't know man, if they can really make rockets in 60 days and target the smaller end of the market they could be competitive. The founders are ex-SpaceX and BO as well-very experienced people and they could move to reusable rockets with more matured tech at some point.

>,or to print even more 3d printers
Semiconductor printing is waaaaay too primitive for that. We'll have colonies on the moons of Saturn before a true self printing machine is feasible.

>>11691942
still, semiconductors probably take up a very small fraction of the mass of a huge 3d printer like that, there's nothing stopping you prefabbing those alone

>>11691995
If you're prebuilding all the PCBs elsewhere it's not self replicating, you just made a shell.

>3d printers are basically von nuemann machines

>>11691998
true but there's utility to 3d printers that can recreate the majority of their structure for human space colonisation, yeah we're not building von neumann probes any time soon but imagine sending printers to mars that can use regolith/local materials to make more printers which can build whatever structure you want, a couple tons of semiconductors could make tens of thousands of them, which would be incredible for isru manufacturing

This is actually the ideal form of a usefull replicating system. The machines can assemble themselves and make all but a few vital components, that need to come from an external source, like our vitamins. If something goes really wrong with a replicating system, you can just starve it of vitamins, and curtail exponential growth

What will happen to SLS when that pulls a Challenger?
They want to put humans on its second flight.

well, it has an abort motor, so we'd have just wasted about one and a half billion dollars, and are about to waste billions more paying the people who blew it up to figure out why it blew up without any loss of human life
essentially an ideal situation, I think

You know that's what would happen... it would be grounded for two years of "investigations", even with the LES having worked and nobody died.

As long as it's on the 2nd flight, humans should be ok.

Because there will never even be a first.

Publicly funded space flight will be pushed back. People will still be able to buy tickets and go by themselves if they want to.
