@@KiRiTO72987 I'm starting to think if I was stood right next to it, looking at it with my own eyes, it will still look like a rendering. It's bonkers in the best ways : )
It looks clean because it's only "partially assembled". What impresses me is how well it fires for a "partially assembled" engine. I wonder what it will be like when it is fully assembled.
@@filonin2Boeing has a "Cost Plus" contract with NASA. Boeing uses unqualified workers and substandard parts. Boeing has taken well over a decade and wasted billions and still hasn't delivered a working capsule. Boeing has been destroyed by Wall Street greed. Boeing is a disgrace.
Honestly, it might be in EVERY nation's best interests to sit down and agree upon on new terms for space use. Where if an upper stage _almost routinely_ turns itself into a cloud if space debris, that the company or country operating it willingly *_ceases_* it's operations until it can be rectified! This isn't any bias against China, either. Simply this: I don't know if those 700 pieces of debris is on the high side of low side for the other 3, but if all 4 of those breakups created an average of 500 pieces of _detectable_ debris, then it's safe to assume there's some that are too small to detect. All of that is to reiterate my opening point: it's in EVERYONE'S best interest to make sure that doesn't keep happening, as it eventually *will* become a problem! _(even at an orbit if only 800KM, space is _*_incredibly_*_ vast, so we're not yet at a huge risk of Kessler Syndrome, but that's why it needs to be addressed now, because it could easily begin to snowball before too long)_
@@DUKE_of_RAMBLE China's leaders doesn't really care, as the loss of earth orbit also denies the rest of the world access. Only the short term goals have any real meaning to them. Especially if they can use LEO to undermine a competitors position.
If you look at the perspective in that shot you will notice that New Glenn is farther away from the camera than Falcon 9. That's why they look so similar in size.
Boeing is stuck in old ways with not the best engineers, and didn’t design a capsule with reliable enough thrusters they can trust to get the astronauts back home.
@@EMichaelBallWorse than that. Had thruster problems on uncrewed tests; and they never did a complete job of fixing the thrusters before flying crew, which is unacceptable in this business in the extreme. - Dave Huntsman
boing holds power over nasa due to how many people it employs in key states, so its forcing nasa to push a unsafe, unreliable, and under-tested to service so they don't lose another major part of their space industry revenue to spaceX.
3:50: Glenn and Falcon were both displaying only their first stages at the port, Glenn also being more elevated on a higher stand thus but appearing slightly taller, albeit them both being roughly equal.
The Raptor 3 engine moved a lot of components inside the metal casing, thanks to additive manufacturing. It's definitely fully assembled, otherwise it wouldn't be functional.
I think Butch and Sunni would be safer just lying on the floor of crew 8's dragon for emegency evac than on strandliner. Scrounge some spare padding and straps from somewhere to make it a bit more comfy for them and they'd be fine.
Bro where have you been, as soon as I started watching and liking this channel you were hosting and next I know they switched commentators by then I was hooked anyway thanks for the space info and glad to see you back doing videos 🖖
Amazing information and beautiful presentations congratulations. Yes 5 launches to SpaceX it's amazing, the ratio is very high. All info from all launches in a few minutes. Tks.❤
You don't get the joke? Raptor 3 was fully assembled, because it is a 3D printed tech. The CEO of ULA didn't even know what he was looking at, which is why Gwynne and Musk are poking fun at him.
I'm surprised that no one asked about space suits. If Starliner departs the station unmanned, there is no place to plug in additional suits into their existing dragon lifeboat. If there were, is dragon compatable with starliner or soyuz suits. Is the current life support system on the dragon rated for seven people? I listened to the briefing, but i did not hear anyone ask the questions. I hope nothing happens between the starliner leaving and the next dragon arriving. Breathing on the way back would be a good thing.
The suits are for emergencies. Plus they look really cool. The capsule itself has plenty of air for 7 people. The three extra passengers would basically strap themselves to the floor wherever they can. And hope for the best.
This was a good podcast. I hardly ever hear about New Glenn. Can't wait for it to start flying regularly. They also need to make a crewed capsule. Boeing has lost its mojo. Scarry, since they make so many defense systems.
The yellow flame from a met/ox engine is from running it rich on fuel, A fuel rich mix is used to reduce combustion and exhaust temperature. This same process is used in every type of motorsports racing engines
The color is due to methane 'sweat-cooling". A film of the propellant is bled through slots in the chamber throat wall. Being oxygen-deficient, the downstream pyrolized and carbonized CH4 products heated to incandescent yellows and oranges. This strategy is used in the Raptor engines as well, and dates back to the German V2, with ethanol injection.
@@-danR Agreed I was mostly pointing out that a slight mixture difference between reliable reuse to RUD. Back when I did speedway carts we had a digital tach and exhaust temp with a mix adjuster because 2 stroke produced max HP when tuned on the edge of melting down. Raptor 3 is a beast of innovation and can't wait to see more
Since Crew Dragon was designed for up to seven crew, why can't they configure Crew 9 with "jump seats" to bring Crew-9+2 back in Feb, instead of leaving two astronauts behind next month?
Guess would be that the archimedies engine burns fuel-rich thereby causing soot particles that'll color the flame yellow-ish (difference between a lab burner burning ox- or fuel rich, easy to test)
I'd guess that the cause of the colour of Archimedes' exhaust is probably the same as the reason why the Raptor has gone from purplish flame colour with Raptor 1 to more orange flames with Raptors 2 and 3. What exactly causes the colour change, I can't be sure, but I'd guess that it's caused by the engines running more fuel rich (maybe to reduce cooling requirements on the combustion chamber?), causing unburned methane to ignite in the exhaust plume when combined with atmospheric oxygen.
Look at the skin between ring 3 and ring 4 of New Glenn as it is lifted. It buckles and leaves clearly visible skin distortion when it is in the vertical. Happens between the 20 and 30 degree mark. Ouch!
omg! i just went back to look at that clip. i had to zoom in to see but there's def something going on there! id be suuuper interested in knowing what's going on with that!? it looks crumpled a bit. is there some way Scott Manley can be contacted to analyse this? if there's anyone who'd know what might be going on there it would be him. he'd def let us know in a vid after researching 🤔🤔
It's a boilerplate, not the real thing. Those are just sheet metal covers on what would otherwise be a basic steel frame and those were seen distorted a long time ago. There is a little bit of real hardware, like the quick disconnects that were tested recently, and obviously the attach points for the breakover fixture ring and the crane lifting cap.
Okay. Boilerplate. How does that translate to an actual vehicle readiness launch schedule? Plus, why isn't the boiler plate not strong enough to lift without distortion?
@@andrewbutler1137the outer panels are just for aesthetics, the whole thing is only meant to simulate the weight distribution, size, and connections of the real thing. The real thing is already undergoing final integration and should roll to the pad in the coming weeks for pre-launch testing - they already moved the second stage for Flight 1 to the pad
@@andrewbutler1137 Because it didn't. It's been like that for a while. It's only generally a mass & dimension simulator, with only a few pieces of "real" flight-like hardware. And I guess you've not paid any real attention. A full stack, real hardware cryogenic pathfinder went to the pad in February, then this went to the pad a month ago to do quick disconnect tests of the GSE, followed in rapid succession by an aft engine module for landing leg tests, and finally a full interstage to test RCS and fins. And now this proves out the breakover fixture for booster recovery.
I liked this team up. Elysia is lovely but is better in small doses and in places where her clear enthusiasm for the topic maybe comes through a bit less. Ryan, as usual, you Rock.
Sounds like no one is willing to make a decision that might come back and bite them. This is what happens when bureaucrats are in charge instead of engineers.
anyone who engages in risk management (like nasa) understands that safety is not a binary property. rather, each potential problem has a severity, a probability, and an uncertainty. based on analyses of these properties, using starliner is far safer than any scenario that would prompt the evacuation of the iss. nonetheless, it is not known to be sufficiently safe for normal use.
@@TheNheg66 nasa clarified this at their press conference. starliner is capable of departing without crew. the specific concern they have is about what happens if starliner has another issue while it's still close to the iss. the starliner software is currently configured to ask the astronauts what to do if something seems to be wrong. nasa wants starliner to be able to get away from the station autonomously under all circumstances. we don't care if the starliner blows up as long as it does it somewhere else.
During Spin Prime Testing, I understand that the tanks are loaded and then LOX and Methane are pumped through the engines without ignition. This means there is a significant amount of Methane vented to atmosphere. I understand Methane is also vented to atmosphere to regulate pressure in the fully fueled tanks. How much Methane is routinely released during the entire coure of preparing one booster? Multiply this by the projected increased incidence of Starship launches and how much Methane will routinely be released during the course of this program going forward? Methand is 10 times more potent a greenhouse gas than carbon dioxide. I would like to see an episode focusing on this detail. While I have seen videos discussing the ecological impact of rocket launches, none have touched upon this detail.
If they do return on crew dragon, how will that work for things like suit connections to the spacecraft? Are the air and power connections universal between spacecraft?
Methane burning at peak temperature is blue, its yellow or red burning at lower temperatures. This might be expected since its sideways on a test stand for a short duration rather than on a rocket.
Gwynn Shotwell was on point! 😂 She provided a picture of the fully assembled Raptor engine in operation. And there has been other photos from SpaceX showing the engine in operation. In fact some of the photos were shown in this presentation but they were cropped not to show the entire engine. I am not sure why this channel want to hide this and keep the speculation going? SpaceX also discussed some of the technology that went into the new design.
I’m a former investor in rocket lab. I only sold because I just had like 10 bucks in it and made like 4 bucks or so, but I think Rocketlab knows what they’re doing. Don’t worry, I’m a KSP player too, so I don’t just take their word for it.
@@QuasariumX Yes, they definitely know what they are doing and they could be running it fuel rich on a purpose. This would mean that the fuel ratio isn't correct as in not the optimal one for best efficiency. I'm sure we'll see it burn much cleaner later this year.
New Glenn looks like a complete vehicle, with working RCS thrusters and all that needs for a successful flight, unlike Starship that uses tanks venting for maneuvering in space, actually Elon itself said that flight3 failed because a piece of ice destroyed one of those maneuvering valves.
@@4DCResinSmoker the mockup doesn't have working RCS thruster, you get confused, Blue has real flight hardware too, beside the mockup that was used for training the personal for various maneuvering techniques, and that real flight hardware has the RCS thrusters and working landing legs to for example, also would be flying in two months so your argument that isn't ready is false.
I would not like to come down on Starliner. First, you need thrusters to make sure you properly enter the atmosphere. You also need them to maintain orientation in the very high atmosphere. I am not sure about Starliner specifically but many capsules as well as the Space Shuttle use "S" curves when hitting the lower atmosphere to bleed off speed during approach which also require thrusters. As for Blue, I am pretty disappointed in their progress.......and I have been a huge fan since they were the first production level rocket to ever land in an upright position. I think they are 6 months or more away from launch. Their landing ship is not even in florida....it has to cross the atlantic. Then they haven't even tested or done a full recovery scenario and then make adjustments. And even when they do finally fly, if they don't hit their landing, I am not even sure if Blue has backup ship in production. Plus, the have their hands in ramping up engine production and are under the gun to get their moon lander solidified. To me, "slow and steady" is very different from crawling ahead millimeter by millimeter hope you will see steady progress
The exhaust colours are orange I'd say because rocket lab have either used oblative cooling which is doubtful because of reuse needs so that leaves the fuel. Rocket lab may be using natural gas and not methane. While natural gas is mainly methane it has other gasses in that spaxex filters out for max performance . Rocketlab are not prioritising performance because of reuse and thus may just use natural gas because they can and it will be cheaper
@@ale131296 I never new that. I always here them say methane regarding the be4. Also Astra specifically says they use natural gas and they have orange in their flame I think. If that's not it, it can only be the engine melting
@@ale131296 it must be relativity. It's 100 percent one of them and the ceos last name is Kemp. I'm 100 percent confident I'm correct it's one of those 2
@@nathanbradforth3408 Kemp is the last name of Astra's CEO, Astra has never used methane or natural gas or any derivative of that on any of its rockets. Relativity's CEO is Tim Ellis, they flew the Terran 1 rocket fueled by LNG and the exhaust was blue - it's in our intro if you wanna check it out
I didn’t know why blue wasent moving towards a fully reusable orbital class rocket, then I remembered they don’t even have a reusable booster yet. They gotta walk before they can run. Decades behind a fully reusable vehicle still
So over the years, with *_all_* of these problems and *_all_* of these setbacks, Boeing needs to ask itself: was transitioning from an engineer-run company to a beancounter-run company, *_REALLY_* the best financial decision for the company?? I'm no expert, but I'm feeling like that answer is a resounding "No." 😒
