- *Yellow* : Liquid Hydrogen - *Red* : RP-1 (Kerosene) - *Blue* : Liquid Oxygen

STS, SLS and Falcon Heavy: all reach final stage. Saturn 5: *there is another*

Hats off to the engineers who managed to launch 4 rockets simultaneously and keep them all level with each other throughout the flight 🚀

These types of animations are so helpful to gain a better understanding of complex technologies. Imagine how many kids who are visual learners would benefit from stuff like this over a textbook. Thanks for the great work!

Shoutout to the cameraman for learning how to fly as fast as rockets

This video is the opposite of clickbait. It’s gets rrright into it

I wish I was alive to see the Saturn 5 take off. That thing looks like a beast.

How long do you want to burn? SLS, STS, F. Heavy: Until we reached our level. Saturn V: yes.

It would be cool to see the speed and altitude with each one.

The Saturn is a thirsty boy

That crackling thunder is my favourite sound, and the random vibration of fittings as if you were in the capsule/cockpit. The comms cap it all off. Brilliantly conceived and executed.

I wanted to list the events so I felt like it. 0:07 lift off (small) 2:13 Artemis - Space shuttle booster separation. 2:39 Saturn V - falcon heavy booster separation. 3:10 Saturn V scurs separation. 3:14 Saturn V launch abort - falcon heavy engine separation. 3:56 falcon heavy faring separation. 8:02 space shuttle external tank. 8:07: 3 SLS stages. core stage, faring, launch abort. 8:46 Saturn V engine separation. Edit: stay happy.

I love how this comment section is a happy bunch of space enthusiasts chatting and dreaming about spacetravel.

"I need to get off my couch and do something productive during this covid day 62" Clear rockets? Ok KZfaq, you win again...

The fire in the solid rocket boosters gets wider over time as fuel burned from the perimeter. Great attention to detail.

Never have I been so interested in watching an hourglass in my life

Well I don't know why this got recommended to me but I'm glad it did

I really appreciate the attention to detail on the SRBs - burning from the inside out. Actually, I just appreciate the attention to detail in general - the engine plumes expanding as the rockets increase in altitude.

Amazingly well done! Loved that the fuel levels decreased, it was shown in real-time synced with actual audio, all separations were shown, and even the relative camera angle changed gradually throughout the whole animation!

I always thought they were just empty helium balloons that just floated up to space. Thanks for clearing that up for me.

I been watching rockets videos for years and this is the coolest, most random video i've seen in a very long time.

Thats so cool to see the fuel prgressively drain out. Gives a sense of how crazy those gas guzzlers are

This does a good job of showing just how much less dense hydrogen (orange) is compared to Kerosene/RP1 (red). It's one of the major considerations when choosing a fuel for a rocket. Hydrogen has more energy per unit mass, but lower energy density (in terms of volume). This means larger tankage. Plus it's cryogenic and a pain in the ass to manage compared to kerosene.

STS, SLS and falcon heavy reach final stage... Saturn V : "THIS ISNT EVEN MY FINAL FORM!"

Such a great attention to detail. Even the exhaust channel in the solid rocket boosters becomes wider as the fuel burns out.

So sick. I’ve always loved space. Born in 86. The early 90s had so many great things going on. Shuttle Missions, Hubble, Mars Rover, Voyager, Manned Mission to mars was being talked about often, the early plans for the ISS, Mir, just amazing! I used to cut out pictures from my National Geographic’s and hang them all over my room. Thought we would be further than we are now. People don’t really seem fascinated by it anymore :/

No wayyyy... WE LANDED ON THE MOOOOON!!

Sort of looks like my inkjet cartridges after printing my thesis.

The effiency of the RS-25 engines is unreal... Damn

That would be a hell of a ride! Cool visualization! It's amazing how long the SLS engines are expected to fire. That's a lot of work for an old set of re-furbished rocket engines

This is cool AF my dude.. So interesting, never woulda thought to make this vid.

And every KSP player is like "wait, my fuel drains much faster than this!" ^_^

If your wondering why the fire from the engines gets wider as it gets higher it’s because there is less pressure from the atmosphere as it gets higher. Since there is less air keeping the fire in a line, it starts to fray outwards.

Absolutely beautiful. And down to a couple seconds of actual timing. Love your work!

Man.. nasa back in the day really pulled a miracle. Saturn V is still amazing

1. Saturn V Payload: Apollo 11 Spacecraft (Command module with it's service module, making the CSM) Lunar Lander/Lunar Module, previously Lunar Excursion Module (Shut up, or I will just say "LM") Stage 1: 5 F-1 ignition Stage 2: 5 J-2 ignition Stage 4B: 1 J-2 ignition 2. Space Transportation System/STS Payload: Discovery Orbiter (Unknown Payload) Stage 1: 3 RS-25, 2 SRB ignition Stage 2: SRB Separation Stage 3: External Fuel Tank Release 3. Falcon Heavy Payload: Elon Musk's Private Tesla Roadster Stage 1: 27 Merlin 1D ignition Stage 2: Side Booster Separation (18 Merlins) Stage 3: Main Engine Cutoff, Stage Separation, 1 Merlin 1D Vacuum engine ignition. Stage 4: Fairings Detached Stage 5: Payload Detached. 4. Space Launch System (SLS) Payload: Orion Capsule Stage 1: 4 RS-25 and 2 SRB ignition. Stage 2: SRB Separation Stage 3: 4 RS-25 Cutoff, Stage Separation, 1 RL-10 ignition.

I laughed when the fairing came off to show the tesla.

That one player who keeps breathing into mic 7:47

Awesome depiction! ... I hung in there for every minute, and half expected to see a shuttle OMS burn ... very cool demonstration. Blessed to work for the 30 year shuttle program at KSC. Thanks!

Imagine: it’s the year 2050 and rocket racing is the new professional sport

It's very dangerous to fire them so close of each other. Please be careful

This is a very educational video and I'll sure share it with others. Thank you for the production!

I have my final exams in 2,5 weeks and I'm sitting here watching clear rockets, instead of learning. Gotta love KZfaq

Was hoping for that payload in the Falcon heavy

I'd never noticed the nose cone release of rockets before. Seems obvious in retrospect but interesting to see it animated, along with so many other little nice details in this video.

Crazy how every spacecraft to date is basically 80% fuel tank.

Reminded yet again that Saturn V was an absolute beast. Way ahead of its time

5:20 I love how everybody is just chillin and Saturn V is like: FIRE!!!

You did a great job keeping the ratios of fuel to oxidizer in the tanks right. It looks odd for the fuel tank to be so small on the Saturn V first stage. But this is correct, as the first stage used RP-1, a type of kerosene and a much more energy dense fuel by volume than liquid hydrogen.

Straight to the point. I love videos like these

Very cool idea! But i think the clouds are visible for too long..

Love how you included the roadster on the Falcon Heavy :D

Dude this was one super awesome video. Thank you!

This was excellent! Well done & THX you! 🚀

This is art. It's not just the rockets that are "transparent", but we're also listening "through the walls" to the guys talking their way through it, as it happened.

This really shows off the fact that 90% of the rocket never leaves the atmosphere

shoutout to the camera man keeping up with the rockets

I was glued to the screen. That was so cool!

in parallel universe youtube: "if rockets weren't transparent"

The men who designed these incredible pieces of engineering were so brilliant. Legends

This is simple but very cool to see, would like to see expanded with all the details of a launch

Out of the many years of watching KZfaq vids, THIS has got to be one of the top coolest that I have ever seen.

All the Kerbal Space Program fans like - y'all need more asparagus staging.

I was transfixed to this video for straight 5 mins without distracted, amazing

I demand more transparency in my rockets! What are they hiding!?

This is one of the neatest and most satisfying rocket related videos I've ever seen!!! Thank you!!!

Man, the SLS sure carries that heavy escape tower for a looong time before jettisoning it.

People say hats off to engineers who managed to launch 4 rockets or to the camera man, but I say hats off to scientists and engineers who were able to create absolutely transparent, lightweight, and strong material that can withstand high loads during rocket launches. Also imagine how much dyer that had to use to make different gases and liquids visible to us.

Awesome & Beautiful! I love the attention to detail!

You should make one titled “If The Government Were Transparent”

This is beyond a level of brilliance that most people ever even imagine.the berd in me salutes the nerd in you.

I love how theres nothing left of the falcon heavy while the sls is still in its first stage

Simple idea, brilliantly executed and visually interesting. Thanks.

Amazing that the Saturn 5 was many, many years ahead of its time.

Listening to an Apollo launch still sends chills. Takes me back to when I was a wide-eyed kid. There’s just nothing that beats those Saturn V’s.

Weird to mix low earth & high earth orbit rockets

I LOVE THIS ! Thanks !

Wow, that RP-1 sure goes quick compared to the HydroLox

Do more of these. I'd love to see various ESA, or even pre ESA European rockets as well.

That was pretty damn creative! Nice video!

This was really cool - thanks.

I really like how you added the detail of the underexpansion of the exhaust

That simple title, and that simple thumbnail. Made me watch this elaborate video 👍✔️

This helps Me appreciate just how complex the fuel is alone and rocketry

Wow, every bit of that 9mins 12secs was fun to watch!

Would be great if there was some telemetry for each rocket as well.

Finally KZfaq algorithm is recommending sensible videos.

Small little imperfection in the video is the Shuttle SRBs and the SLS’s SRBs separating at the same time, SLS’s SRBs burn for a longer amount of time because they are five segment boosters instead of the four segment ones used on the space shuttle

Not sure if someone already commented on this but in case you didn’t know the reason why it looks like a thin line is burning down the length of the solid rocket boosters is because they have a hollow core so that the entire length of the rocket is burning to produce maximum thrust.

The Saturn V was such a brutal, awe-inspiring muscle-rocket. Efficiency goes out the door in place of a bigger rocket motor. :)

This really highlights how “getting up” and “going fast” have vastly different fuel burn characteristics.

No accident, No overtaking, no racing. Smooth and balanced. Nice😀

So damn cool, thank you so much for this

Love the Tesla Roadster on top of the Falcon Heavy

That kind of fuel consumption is NOTHING compared to a modern Volkswagen car.

AWESOME!!! That was very intresting, good job.

That is goddamn amazing. I just subscribed :-)

The fact that the shuttle didn’t do its OMS burn triggered me greatly

3:17 I really like the detail in the Falcon 9 second stage's nozzle. As they say, "glowing red".
