Starship Troopers! - Věda a technologie
It is unfortunate that the huge channel logo obliterated the speed and altitude feed. Not the best planning.
It should have been in the top right corner if needed. Really annoying
Sorry guys.
That is some incredible plasma footage of the Starship atmospheric re-entry!
Is is indeed!
The highlight of the trip for sure
Never seen anything quite like it!
So pretty! The all black bottom makes Starship look like a Star Trek villain's vessel. I was so happy to see this.
It was beautiful!
Oh my GOD the plasma! How incredibly amazing! I can't wait until they get through the whole reentry.
It's the first time we've ever got to really see it...
It looks to me like the booster ran out of fuel before it could slow down to a soft landing. I wish they had a boater's view of that. Something crashing vertically into the ocean at almost Mach 1 would have been pretty cool to see.
Noway it ran out of fuel or no way that caused that failure. Clearly vehicle wasn't under control at engine relight
Would be interesting to find out the investigative enquiry finding on this! How about a disposable barge viewed by a remote camera?
Booster blew up again.. LOS above the clouds... so it probably repeated what happened on IFT2
@@johnny4498 it's the other way around, engine relight failed and spun it out control
@@tedarcher9120 Wrong! Booster clearly has roll oscillations before relight!
Love the pez door intermission. 😂
Thank you! :-)
Nice thanks for putting this together.
You are most welcome...
Been watching launches since the first Mercury sub-orbital. This was the most exciting launch yet.
I’d rate it 98% successful. The next flight in certain the booster will do fine.
Re-entry I’m not so sure about.
But hot dog, what gorgeous video!
It was amazing!
I would disagree somewhat. They made orbit, a biggie! With the loss of both vehicles outside of the flight plan, I would say about 75% successful. Some significant "new" problems popped up, as well as a continuing problem (the engine relights)
So awesome! And so sad all at the same time…
It was indeed.
There was no attitude control whatsoever! They have a lot of work to do as right now all they have is a great big firework. I’m surprised that SpaceX under engineered that as badly as they did, otherwise, they did ok for an engineering flight. Methinks a cold RCS system is a no-go. Bring back something with some oomph like the Draco’s, otherwise they have a serious problem.
The air was too thin for aerosurfaces and too hot to wait :-)
@@terranspaceacademy Indeed, that’s why is was surprised at the lack of robustness in their RCS system. Remember kids, tumbling on re-entry BAD!
Starship did a Columbia imitation
That is a sick f'in joke. Astronauts were killed. You really need to delete your post.
Not really.. They had no control.. it was tumbling in.. it was ass first for a good amount of time, then It was sideways for a bit (into the plasma stream). They must have lost RCS control, and the flaps looked confused as to what to do. They'll figure it out.
Columbia was damaged on the way up and a leading edge failed. Starship just needs better RCS.
@@terranspaceacademyCan you explain what RCS stands for?
@@GreyDeathVaccine Reaction Control System.
It's using little engines to rotate or maneuver the craft.
Good luck with those tiles, genius
They'll work it out... or go to active cooling.
+1 for stats!
Thanks!
Need better/stronger RCS thrusters to align ship and booster?
That's correct. We'll go into that this week. The flaps don't have enough air and the RCS is not nearly powerful enough.
I really feel like they didnt have enough excess pressure in the lox tank to even use any rcs during that entry. I didnt see any real attempt to correct the roll, it looked to be just free falling until the fins had some atmosphere to attempt to work with.
Love how the grid fins were fighting the good fight right until the end.
@novanights2chevy597 Wonder whether the booster hit a layer of high wind on the way down. High winds were reported at 3000 ft before launch, which was a concern for them.
@@trevorleaman2525LOS was above the clouds, and two engines tried to start. one of center engines, and one outer. The outer went out almost instantly. I think it repeated IFT2, and blew up from engine fail. The booster fail was the one that bugged me the most. There's other stuff happening in there they have to figure out.
Amazing "loss of flight control" announcement! Similar for booster engine relight, very insightful!
Thank you!
Thanks for this!
I was hoping you'd provide a bit of analysis of what you thought happened, but perhaps that will come a bit later.
You are most welcome. That is correct :-) I'm going to review active thrust vectoring, RCS thrusters, and transitional airflow in the next lesson.
Great video. Thrusters definitely need improvement, & it's surprising that starship's flaps are not airfoils. A odd choice as lift generation would allow a reduction in thermal loading.
Thank you. They don't want lift so much as drag as I think...
@@terranspaceacademy Agreed drag looks to be the concept, but a airfoil could be designed to generate massive drag & lift. Would be a improvement as lift directly acts against velocity in their flop maneuver. Lift also generates dramatically less heat than drag.
Actually seeing the fuel slosh during rentry for both stages is MASSIVE data.
Amazing work by some very smart people...
Where did you get the information on the fuel levels at the start?
The 1,200 for the Starship and 3,400 for the Booster? Those are published by SpaceX, though they might have gone a little light this time so they didn't need to vent as much.
Is there any chance that traniting from super sonic to sub sonic is what caused or contributed to instability of the booster on landing? I note that we start to the grid fins rapidly actuating around 1300 km/hr which is just above the speed of sound at high altitude. I imagine that instability then caused fuel-slosh that prevented the raptors from igniting as planned.
You are quite right. The transition phase will have some aerosurfaces in subsonic airflow and others supersonic, creating tremendous instability that used to tear apart bombers in a powered dive, and helped destroy Virgin Galactic's Spaceship Two.
Booster needs RCs thrusters and fins at the bottom! To get better descent, just my opinion. 🙂
Definitely more powerful RC! :-)
What do you think of John Powell's airship to orbit?
Still trying to wrap my head around thrust to weight ratio issues...
The upper stage have a really bad shape for a stable re-entering, they should be using dragon design with a ceramic heat tiles at the bottom, and doors within to alow engines to fire and be protected during the hottest phase.
I would go three stage with the second and third coming back like Stoke space if I had the choice.
@@terranspaceacademy with specific impulse of starship engines two stages is better for LEO, and three for the moon or other high energy orbits, but yes I do think too that Stoke have a better design for the upper stage.
Are they expecting it to constantly bleed propellant all the way to the moon and Mars?
They do that to prevent that fuel from splashing down with the ship
That's just for reentry... Like when jets dump fuel before landing.
Not much on long duration flights no. Here they are likely getting rid of excess pressure due to boil off after the spicy launch, then an engine chill sequence for the relight that was planned but didnt happen will be pouring out lox vapor for a bit.
Do you think the overall heat load killed it? How much would a breaking burn help?
I think it came in too sideways and tail down... But that's just my guess...
Probably fts triggered. Otherwise it would have made it
👍
Thanks! :-)
The Booster seemed not to re-ignite. Likely because of fuel movement. Why not keep one engine, running at minimal thrust, say, 50%, to slow the vehicle and keep the liquids properly positioned? On the Ship (second stage), it also seemed like re-ignition after coasting was a problem. I saw in the Lance missile program (1970), a piston was used to move the liquid propellants toward the motor. Perhaps something similar might be of benefit?
Yea the booster has some problems. I think it blew up like IFT2. LOS was above the clouds. They were able to do a full boost back burn, so all the fuel should have been well planted. Even in free fall, the fuel should still be planted, as the ships air resistance would make it "fall" slower then what the fuel inside wants to... if that makes sense (terminal velocity differential). It's probably plumbing related again. We'll see!
Something strange happened, that's for sure. The wild spinning might have pulled the propellant to the sides and starved the center engines causing a feed problem and explosion...
No analysis? I think we all watched the launch and flight.
We want to know what is going on with Raptor engine relights, and if the Pez door failed. And what was with the SS instability? How fixable is that using the remaining, already completely SSs? Will they need to scrap them and redesign?
Shape my friend...They should have stayed with the original CTS shape.
I look forward to hearing more about this in your next video. "Shape" doesn't sound like something they can fix with the existing SSs on the property. By "shape" are you referring to the "pointy" nose that Elon wanted instead of the less attractive rounded nose of the Bezos ship?@@terranspaceacademy
Very strange! I have already seen multiple videos from other sources of the starship all the way to 0' altitude over the ocean for today's launch!
Hopefully someone got footage!
Would have been nice if you had left links to all that.
Suggestion: Put your patch in the top right-hand corner so as not to cover the ship telemetry in the bottom right-hand corner.
Will do, thanks
Ok, great we know who you are, don't block screen content when rebroadcasting other content, not yours with your ego-based logo.
You do fantastic work, at least increase the transparency to see relevant content presented by the original provider.
You do great in providing educational content we thank you.
😀
That was a total error on my part. I was looking at livestreaming and decided not to. The logo was only for that but somehow transfered over when I rendered.
I'm no scientist, but isn't almost 26k kmh way too fast at just 65 kilometers? Would they have had enough time and height to slow down to their target speed? Or do they need bigger fins possibly if not?? Overall it was great to watch it.
Removed my RUBBISH 😂
That's true... and without optimal positioning it wouldn't slow down as much as planned.
That big bitch was completely out of re-entry profile and was nothing but a meteor. If you watch the re-entry footage Starship was tumbling and never had a chance. They really need to rethink their attitude control system. I’m sure the aerodynamic profile will work below say 150,000 ft but relying on the wings to orient the vehicle was nothing short of engineering folly!
Interesting point, but I have to think that was calculated. The booster has to do what it has to do, right? Thinking 'out loud' so to speak.
Hello
Hi!
17:49/21:20 What was this guy so mad about? Wow!
I didn't see anything to suggest he was mad. No one is paying any special attention to him.
I think they are "safekeeping" the data.. Sorta like "lock the doors" at NASA. I took his aggressiveness to be urgent, and not combative.
He was in charge of the booster relight sequence :-)?
Wow Go back and look again. This time don't watch him. Watch the other guy that was setting next to him and the guy at the back roll. @@stratolestele7611
@@terranspaceacademy🤣🤣
Great time to stretch the booster and ship due to cryogenic fuel and oxidizer loss
Stretch them?
Booster didn't soft land and ship didn't survive re-entry, but what the main media outlets wont tell you about are the hundreds or thousands of self tests, terabytes of telemetry data, structural and control validations, and other many milestones SpaceX accomplished today. Geaux SpaceX, Geaux Team Space!
further each time and they weren't going to survive anyway.
A centrifugal tank for space re lights of the engine.
Centrifugal tank?
@@terranspaceacademy My own idea. A spinning tank to allow the liquids to stay seated.
Test 4 will probably be full orbit. Test 5 will be completing a Dragon to Starship docking maneuver to showcase flexibility and potential of their interconnected systems as framework to build a station out of 10 conjoined starships by the year 2027.
The 10 ship array will be tested as an interplanetary mega ship that sustains artificial gravity with aid of giant mirrors that serve as solar power collectors that double as solar sails.
Picture 10 nose to nose star ships that swivel at the nose, picturing them horizontally to see them as being sandwiched between one top and bottom mirror layer. The mirror layers would expand outward to only 2/3rd the distance away from the centrsl point of rotation at the nose of the 10 star ships.
These mirrors will be able to deflect most harmful radiation, even using that radiation as extra thrust in propelling the giant snowflake structure through space.
A series of such snowflakes can serve as sigal boosting relay points in the information highway of inner solar system life. They can even assist in funneling a lazer highway to bring ships up to and down from 5% light speed.
That would be awesome
Watermark over the Starship's telemetry...
I know... It didn't show up when I was recording but was there on rendering.
I don't understand why Starship continues to burn the atmospheric engines, even after the vacuum optimized engines are shut down. Ant idea?
I was wondering that too but since they aren't going into orbit it might be a way to get rid of excess propellant and have better vector control.
Could be for better control. Less thrust so it will reach the target velocity slower while having the bonus benefit of thrust vectoring.
The atmospheric engines are steerable, vs the vacuum engines that are fixed and not steerable. So they can tweak the attitude of the vehicle if the other engines don't all shutdown simultaneously and a yaw or pitch is introduced.
Agreed, though there is other ways around it, differential thrust and of course rcs. But I think you are right in this case. @@lmamakos
All of the above possible. I'm also wondering if it's for stats purposes?
IT'S BURNING UP )! YIPPEEEEEEE !!! YAHOOOOOOO )!!!!
He's a done Tom turkey!
Logo is the wrong place!
I know, I know...
Cheerleaders are you guys going to develop standards. There are 4 more rockets just like this one. So all the bad design features are not being addressed. To circumvent the destruction of the booster they initiated hot staging a full minute early while only reaching 70 kilometers. Then it still went out control and belly flopped on the ocean. I did like the instant cutaway and acted like it never happened. Then bacause of a way to early shut down of booster starship had burned almost all its fuel. So it coasted from 178 kilometers to 228 kilometers before falling back to earth. Just a note starship from engine shut down till engine failure to relight. He has it was venting fuel fuel clearly seen from onboard cameras. This as a result of damage to gimbal engine damaged fuel nozzles from the flat hot stage ring. Then as I stated before launch as it enter the atmosphere the tile stared peeling of the non stick stainless body. The video showed the insulation and tiles fling off before reaching terminal velocity that burned up the rocket. Loss of signal at 65 kilometers. Starship payload door opened but was unable to close. So at 90,000,000 a copy how do cheerleaders get a success.
If this was a success then why even launch the next 4 more of the same rockets. Last the booster is the most powerful rocket to date. But all we get is 2.42 seconds and 70 kilometers?
Without a change in material and total redesign of boosters 33 engines. This is as good as it gets.
I see... total failure I suppose.
Why you put your seal on bottom right corner of the screen? There's important info there about the ship's performance.
I had set it for livestream and when that didn't work out nothing showed on the recorder.
No need to ‘watermark’ someone else’s live feed with your logo.
For the last time... hopefully... that was for the livestream that failed. It was intended to come through on the rendering.
Booster blew up again.. LOS above the clouds... so it probably repeated what happened on IFT2. It'll be a long time before they try to grab one of those! God bless those hedge funds. Main ship.. the door is a joke. Didn't hear anything about engine relight. The fuel transfer may have messed that up. Loss of RCS control for reentry orientation... Sucks it'll be 3 or so months before the next one.. Investigation - boom- Investigation- repeat.
If they just went expendable to orbit to start with. Setting up an orbital lab. They would be better off for HLS.
Now what I'm saying got nothing to do abouthis isn't or speech? But when you speak, live and bring things across to get your point across the word. Do come up to take the place. A pause to make sure you say what you want to say correctly. So I sit there and say well, how many times with the word? We'll come up with the correction women or quote. You might say white or a person with a great. Persian.
You may need to put a little less screw in the driver my friend. That wasn't very coherent.
Chat GP zero.@@terranspaceacademy
That doesn't even reach the level of a 'word salad'.
It's OK, now, I know for a fact. Everybody is not the greatest speaker when you on camera and the camera in your face right in there. And when you speaking still using the word and you might use the word. Um That is pretty much normal when you got a camera and you love talking. When you are talking. And not reading off a piece of paper. That's normal, but what the guy was telling me carcasion. People do not use the word that Um That much. But it's not true when you go live speaking. Call lab speaker. So let's see how many times this Caucasian woman. A quote white woman used to work as a example. And this gentleman to me little like he is A. Agent Indian descent. Go sit. Does it? Now he might been American Asian.
He's a kid being watched by 5 million people live! Cut him slack :-)
Wow! I guess I'm not looking at things the right way. I saw humans commenting on a significant human event for the greater good of all humanity.... Darn. I just feed a Troll. Dang it!🙄
Mirror mirror on the wall where is booster 10 and ship 28?
In the drink...
Davy Jones Locker. AArrrrrr!
Mirror mirror on the wall how dont you see it?
Because it's not there?
The spin SpaceX does when they fail is just mind-boggling mental gymnastics.
All they've done is invent the world's most expensive fragmentation grenade and foster a CZcams community whose livelihood depends on people watching this.
It will never work. Not without endless money.
Nonsense. Strive greatly fail spectacularly succeed greatly
Who wouldn't want to watch this. The west is jaded and tired if you cant be inspired by this spectacular experiment
That's nonsense. Then again, where are all the experts who said the OLM's water deluge system would cause a massive steam explosion and take the OLP, the entire launch pad, and the rocket with it? I mean, there were some 'engineers' who proclaimed very bad things about the water deluge design with absolute and total certainty.
Seriously? It worked as well as any other rocket in history. All they ever did was go up and throw away the first stage. Go to space and throw away the rest.
@@terranspaceacademy "All they ever did..." was put humans on the moon, have successful space stations, land rovers on Mars, return samples from asteroids, have space craft tour the solar system AND leave it...
Corporations and exploration never mix well.
