The Orion capsule used in that test has nothing in the common with the Orion currently flying other than its shape. If I recall the point of the mission was to test the heatshield at lunar reentry speeds but I think they ended up redesigning the heatshield anyways so it ended up being a pointless mission. Just something to give the illusion that more progress was being made than actually was

>>15034278
Nazis don't need more than their wristwatch and a timetable to go the moon.
That's the real reason we haven't been back. No more Nazi engineers.

>>15034285
They were so autistic about mass they optimized against expected thrust and throttle requirements

Except the CSM, because that was designed for actually landing on the moon directly without the LEM

>>15034293
Sheer fucking hubris

>>15034292
Did you know all Indians launchers run on Nazi-designed engines?

>>15034299
explain I thought they were all euro or russian derived

>>15034288
They had one booster for unmanned (now splattered on the desert floor) and one for manned, plus one on display

>>15034257
It didn't, pic related did.
That thing was pretty much pushed by pic related to the Moon, then just went back to Lunar orbit and then they just left it there after the astronauts went back into the CSM.
The Lunar ascent stage either crashed into the Moon, or is still drifting around.

>>15034288
Space is hard.

>>15034309
The CSM is cute, cute!

>>15034285
Descent needed a throttle and restart capabilities, CSM needed a bunch of restarts, and ascent needed neither. The CSM and ascent engines were generally just improvements on existing engines, but the descent engine had very specific needs and had to be engineered pretty much from the ground up.

Using the descent engine for everything would have been inefficient since it weighed more with roughly the same capabilities as the CSM engine, which had no need for its throttle.

>>15034316
Perfect down to the most minute detail

>>15034322
>explodes

I finally tested the latest engine attempt and it went pretty badly. It was way too fuel rich and wouldn't burn inside the chamber at all. I've been trying to tune the fuel flow rate with water tests, but I can't seem to get it right. Its also definitely possible that I'm still having injection issues. I'm a little suspicious that the fuel tank might not actually be achieving 300 psi. The water tests haven't seemed as powerful as I expected.

I think what I'm going to do is switch to autogenously pressurized propane. I can count on about 100 psi of vapor pressure, so I think designing around 67 psi of chamber pressure is pretty reasonable. Performance is going to be pretty pitiful, but I think this is the best chance I have of getting this thing working. Pressurization will be a non issue and I think it will make mixing a lot easier too. My injectors seemed to work a lot better back when I was using propane before, so I think its a bit more forgiving.

>>15034325
4ASS shock diamonds for XMAS?

also, based. Keep up the good work

>>15034275
By fully counteract you mean make a safe landing right? But parachutes create drag instead of producing lift, so anything that uses parachutes to land instead of lift alone, like the space shuttle, isn't a space plane right?

>>15034324
Shuttle explodes and kills its astronauts
Apollo CSM exploded and keeps them alive
They are not the same

>>15034225
Remember when VolksWagen gassed a bunch of monkeys to test its car emissions.

>>15034328
I mean that while in the atmosphere, under fairly normal operating conditions, there exists some angle of attack where the force from lift is greater than the force due to gravity.

>>15034294
>Except the CSM, because that was designed for actually landing on the moon directly without the LEM
Hol' up

>>15034340
He’s right; the original plan was to just slap some legs on the CSM. Hence why it’s AJ-10 is comically overpowered. They ended up just keeping it on there because the mass ratio fit after everything else was finalized and NASA decided it was better to keep it than nerf it down, as it was the most important piece of hardware needed in the event something went wrong

>>15034301
Both PSLV, GSLV and LVM 3 use Vikas engine as upper stage, which are licensed versions of the french Viking (although with subsequent improvement for LVM 3) which Was designed by Karl Heinz Bringer, a peenemunde engineer and propulsion manager who was a friend of Von Braun and patented the modern gas generator cycle engine, The Viking was basically his Magnum opus.

There’s some video out there of him talking about the Viking and vikas in tbe 90s In french with a stereotypical German accent, will have to find it.

>>15034357
The funny part is that until the early 70s he (and a bunch other "paperclipped" german engineers) was kept in the utmost secrecy by the french, up until the Europa program failed. Then to promote Ariane/LIIIS as an European program, they "declassified" him and showed him off to the Germans as a proof that German-French cooperation could work, basically "see: your Nazi can work with us! now gib funding for CNES and Ariane pls"

>iss068e025819 (Dec. 2, 2022) --- A set of four CubeSats are photographed after being released from a small satellite deployer on the outside of the Kibo laboratory module as the International Space Station orbited 264 miles above Namibia on the African continent. The four tiny satellites, two from Japan, and one each from Uganda and Zimbabwe, were deployed into Earth orbit for a variety scientific studies and technology demonstrations.

>>15034364
https://www.peta.org/action/action-alerts/monkeys-abused-volkswagen-inhalation-test/

Are CubeSats based or cringe? I'm completely torn, but I'm positive they fall on one extreme.

>>15034464
Based, because they're about as cheap as it's possible to get in spaceflight

Cringe because you're basically expendable compared to some nation-state's billion dollar baby

>>15034166
>>15034143
A whole cubic kilometer of monkeys

>>15034464
They're the visible result of Moore's Law. Satellites used to be big because they had very primitive computers, or even analog film cameras with orbital canister drops! Now a cubesat with some clever antenna technology can fully replace a large satellite for many missions, or a teeny little 1U can at least be an entry level mission. This is what TROPICS is all about. Larger satellites are now driven by things other than electronics: instrument size, power budget, propulsion system, etc.

woodsats are based because they make material scientists seethe. yeah, it always was that easy

Water is SUPER dense compared to LH2, anon. That thing's going to have a mass ratio of like 40 and a small plasma magnet won't provide much acceleration until the ship is running dry. Water NTP also caps out at an Isp of ~450s. Even with a mass ratio of 40 that's only ~16km/s dV. Cut your water prop volume in half, put the sail fore instead of aft, make it 5m wide, and double the power going to it. You only lose ~3km/s from water NTP but you 10x the amount of dV you get from the sails.

>>15034697
You uh, do know that the plasma magnet sail coils are fucking huge right? Did you even watch the videos explaining it? They need to be at the bow. Also if you are assuming that the plasma magnet sail works for the fantasy starship then you might as well use the advanced concept of using plasma magnet coil windmills to power giga nigga ion drives going sunward rather than some nuclear shit.

>>15034794
In his defense, a single plasma magnet with ISRU capable bimodal NTP is about the optimum near term design. You need impulsive maneuvers to escape planetary magnetospheres, and to brake on intercept on an outbound leg. The Q ship you're describing is geared all wrong for interplanetary travel, it's for far outer system missions or interstellar, and it needs to be tens of kilometers long to space the plasma magnets out enough.

Tourist here writing a story with a space question.

If there was an object around 400m long (about the dimensions of a modern day aircraft carrier) orbiting around the moon, how difficult would that be to detect from Earth? Assuming it was always there, when in history would humans first discover it? The first radar surveys of the moon?

>>15034983
I'd say detected in the early 19th C., depending on its albedo and orbit - too dark and too close to the Moon means harder to see

>>15034672
I'm expecting a written letter of apology.

>>15034697
This image made me want to start up FreeCad and build spaceships

Are there any examples of bipropellant cryogenic RCS systems? Or just everyone just use hydrazine.

>>15034992
but too close to the Moon means almost certainly an unstable orbit because of mascons
anyhow certainly an astroonomer would have noticed a fucking skyscraper building moving against that gray

>>15035011
'noticing' is not the same persuading your peers that the fleeting glimpse wasn't eyestrain and nailing down a correct orbit for the object. 19 C. journals have a lot of reports of odd things moving across the Moon btw, see Charles Fort's books for examples

>>15034655
>>check kpop news as usual

>>15034503
No, they should keep proprietary time. To submit a JWST proposal you have to plan everything up front, there is no phase 2 like other telescopes. Every dither, every exposure, every filter change, it all has to be planned and correct. Even for a small proposal this takes weeks to do properly, it complicated. And after all this you had only a 25% chance of success, that will be even lower in the future. It takes a lot of time and effort to get time, there needs to be some reward for people who come up with novel programs and strategies to maximize the scientific efficiency of the telescope.

>>15034992
Fucking Phobos was discovered in 1877, and it’s got a low albedo and is close to Mars

Depending on distance and albedo I’d say it would be between "Known since ancient times" and "17th century discovery"

>The trunk consists of solid rocket fuel. Its leaves are described as having a yellow color and looking like a cross between moss and wool. Its bark is gray and it produces flowers. The stage tree has two lifecycles, the bush form and the multistage form. In the bush form the stage trees reach heights of four to six feet and are described as slender and straight with brilliant yellow foliage at the top flattened like a dandelion's head. If a seed finds particularly fertile ground the bush enters the multistage form. In the multistage form the living parts of the tree consist of the tap root and the yellow foliage around the base. The center of the tree is devoted to creating a gray dead-looking spire of solid rocket fuel reaching heights of up to half a mile with a seed pod at the top. When the tree reaches maturity as indicated by the graying of its foliage the spire ignites and takes off like a rocket leaving the solar system is in. It floats in interstellar space for hundreds of thousands of years until finding a new system where the seed pod explodes, if a habitable planet is in orbit and a seed lands on it the cycle starts again

The whole "focus on inspiring people" schtick never works. Normies don't care about Artemis 1 because an unmanned capsule floating near the Moon is not exciting in any way. The only things that grab normies attention is either milestone manned missions or meme missions like the Falcon Heavy demo launch.

Here is my take:
It’s already hard to hold the attention of the general public on this matter (as evidenced by the rapid decline in public support of Apollo pretty much right after Apollo 11 returned)
On top of this NASA has spent decades hyping a Moon program, cancelled Constellation, and then let SLS delay for nearly a decade only to launch it at like 3AM when almost no one was awake. Orion itself has been doing nothing for nearly 20 fucking years—it should be a surprise to no one that the Shuttle is fondly remembered as a space ship that worked but almost no normies even know Orion exists.
NASA apologists will claim this flight sees little interest because there are no humans aboard, but look at JWST or Curiosity or Perseverance. Those had zero humans but stayed in the headlines for weeks
Artemis doesn’t generate hype because it’s underlined by vague goals, deadlines that are pretty much just expected to not get met, and if they are trying to prop it up chiefly as “first woman first POC” then the second that goal gets met the small amount of people who actually learned about it and got excited will move on just like Apollo

>>15035350
>>15035417
Come to think of it the FH demo was INSANELY publicized. Idk how that happened. Starship is an even cooler rocket but my gut tells me even its orbital attempt will only get a fraction of what FH saw (in terms of normies, not autists who have been following it this whole time)

>>15035407

great stunt for SeX and tesla

As I logged into the /sfg/ forum, I couldn't help but notice the handsome face of Robert Zubrin staring back at me from his profile picture. I had been a fan of his work for years, and I couldn't resist the urge to send him a private message.

"Hello, Mr. Zubrin," I typed, my fingers trembling with excitement. "I just wanted to say that I'm a huge admirer of your work. Your passion for space exploration is truly inspiring."

To my surprise, he replied almost immediately. "Thank you, /sfg/ user. It's always nice to hear from fans of my work. I'm glad to hear that you share my passion for space exploration."

As we continued to exchange messages, I found myself drawn to his intelligence and wit. I could feel a connection forming between us, and I couldn't resist the temptation to take things to the next level.

"Mr. Zubrin," I typed, my heart racing with anticipation. "I know this may seem bold, but I can't help but feel a strong attraction to you. I was wondering if you might be interested in meeting in person to explore this connection further."

To my delight, he responded with a resounding "Yes!"

We arranged to meet at a nearby hotel, and as I walked through the doors, I could feel my heart pounding in my chest. I found him waiting for me in the lobby, looking even more handsome in person.

Without a word, he took me by the hand and led me to his room. As soon as the door closed behind us, he pulled me into his arms and kissed me deeply, our lips and tongues tangling together in a frenzy of passion.

He pulled me down onto the bed, his hands roaming over my body as he explored every inch of my skin. I moaned in pleasure as he touched me, my body yearning for more.

We spent the entire night making love, exploring each other's bodies in ways I never could have imagined. As the sun began to rise, we lay tangled together, our bodies exhausted but our hearts full.

>>15035429
Ah that’s a really good point

>>15035426
You have to remember that SpaceX was in David vs Goliath situation. A private company managed to build and launch the most powerful (and reusable) rocket before NASA. So if that wasn't enough to make a big headline, you also have Elon Musk himself and a Tesla Roadstar as payload, launching towards Mars.
Your guts may be wrong, Starship launch, as an event, has almost all the perks that FH did, except the interesting payload, unless they manage to make a cargo version in time and load a Semi inside, but I doubt that. The additional advantage is that the orbiter, just like the Shuttle is huge and it's coming back to Earth in style, instead of a puny capsule.

>>15035455
>reusable rocket before NASA
Like that's some kind of race... and as far as NASA is concerned, Shittle was "reusable". Rebuild some engines, refill some tubes, but pay no attention when you throw away a big tank.

>>15035466
That's why I put it in the bracket. You can't deny that there wasn't a race between FH and SLS.

Ingenuity is still alive and managed to hit another milestone.

>>15035469
But SLS isn't a resuable rocket. The only part of that whole stack to be reused is the capsule.

>>15035482

>A delusional spaceflight fan is someone who is obsessed with space travel and exploration, but has an overly optimistic or unrealistic view of the current state of spaceflight technology. They may spend hours reading about space exploration and analyzing news articles and scientific papers, looking for any evidence that supports their beliefs. They may also engage in online discussions with other spaceflight fans, trying to convince them of the validity of their views.
>In some cases, a delusional spaceflight fan may become isolated and disconnected from reality. They may withdraw from social activities and spend all of their time and energy focused on their beliefs about spaceflight. This can lead to mental health problems and social isolation.
>It is important to remember that while space exploration is an exciting and important field, it is also subject to the laws of physics and the limitations of current technology.

Crappy lunch windows and an eagerness to get the damn rocket off the pad. They couldn't go later or earlier because the outbound trajectory couldn't linger in Earth's shadow for longer than Orion's batteries could hold out.

I'm sure they made fun of Mueller too. It's just that when you're a rocket scientist and you just happen to have a big jug of liquid fluorine or pentaborane you actually get to go and do the dumb idea that you laughed at.

It's impossible to generate hype for a shitty capsule in 2022. The Shuttle may have had multiple problems, but it set certain expectations among normies, about what a space ship should look like. At least Starship looks futuristic, especially if they pull off the landing on the tower, which will generate a lot of hype. Then missions like Polaris and Dear moon will blow people's mind, with the amount of space that Starship has, compared to the ISS.

Male and female kpop idols can be distinguished by a number of methods. One common method is to look at the idol's vent, which is the opening through which the idol excretes waste and, in the case of female kpop idols, lays eggs. Male idols typically have a round vent, while female idols have a slit-like vent. Another method is to look at the idol's hair. Male idols often have hairs that are longer and more pointed than those of female idols. However, it is important to note that these methods are not always foolproof and can sometimes be difficult to use, especially for inexperienced people.

It would be difficult to detect such an object from Earth. The first radar surveys of the moon were conducted in the 1950s, so it is likely that the object would not have been discovered until then. However, it is also possible that it could have been discovered earlier through visual observation with telescopes or other instruments.

Q: Please tell me what to post in order to make other people stop posting irrelevant time-wasting nonsense.

A: It's not really possible to make other people stop posting irrelevant time-wasting nonsense. However, if you want to discourage this type of behavior on a forum or discussion board, you can try setting up clear rules and guidelines for posting, and enforce those rules consistently. You can also try to encourage more constructive and relevant discussions by starting interesting and thought-provoking discussions yourself, and by responding to posts that contribute to the conversation in a meaningful way. Ultimately, though, you can't control what other people post, and the best you can do is to create an environment that encourages more constructive and relevant discussions.

The upper stage is pretty heavy. The original plan was for New Glenn to have a methane second stage for LEO and a hydrogen third stage for GTO/Lunar. The methane second stage was scrapped in 2018 when Blue big for the Space Force NSSL contract, in favour of a stretched hydrogen third stage with two engines

New Glenn will be better than Vulcan Centaur and or Ariane 6 simply because it is reusable

At least NASA is (supposedly) throwing in some pretty hefty sustainability goals—so it will need to be pretty big. If they just submit the exact same design again, with the expendable descent stage, then we will know this is 100% a sham just to give out money with no actual sustainability goals being expected

We tried to warn you. We tried to prevent this. You could have had OmegA instead of New Glenn. You could have had a nice lander. This is what you deserve. This is the future you chose. Goodbye forever - Northrop Grumman

Not displaced, it's just the entire production lines, companies etc are long gone.
With the money it would take to recreate them you can just make a new one from scratch instead.
Same as with the Saturn V.
