What is block 5 of Falcon 9? Why throw non block 5's away?

Published on Mar 12, 2018
Block 5. The elusive final iteration of SpaceX’s Falcon 9 rocket is finally almost here. Although we’ve known quite a bit about what’s going to be new with Block 5, the general public has had a very hard time understanding what, when, why, how, huh’s when it comes to block changes.
Well today, we’re going to try and untangle the confusion of block changes, revealing the history of the Falcon 9 and how its evolved into the fully and rapidly reusable rocket we hope to see with this new ultimate Block 5 Falcon 9.
We’re also going to do a side by side comparison of all versions of the Falcon 9 including Block 5 to show you just how much is changing before SpaceX commits to freezing the Falcon 9 so astronauts can finally ride on top.
And lastly we’re going to explain why SpaceX has been throwing away some of their older Falcon 9’s before they get into this new Block 5 booster.

  • I wanna have falcon 9/heavy models as my toys

  • It's like upgrading the skyward sword

  • Block 5 ftw

  • Where do you get the models of the rockets?

  • make the whole rocket black. It makes it easier to see. It is more clear, about size, and other mods.

  • Where did you got a Falcon 9 model???

  • For Elin proclaimed "Thy block 5 come" And the Falcon Nine did be _YOTEN_ to space above.

  • Where do you get those amazing models?

  • I've never understood how a controlled landing using rockets could be less expensive than parachutes? It looks cool but you'd think a combination of speed brakes, a drogue chute and a set of big main parachutes would weigh less and cost less.

  • Interesting video, but I really don't understand why we progress to keep using Rockets to go into space? I watched a documentary where scientists built a force field made up of layers of hot and cold plasma's. So in theory, if you remove the atmosphere from in front of an object you don't need to use huge amounts of thrust. Therefore one could fly something like an Airbus A380 into space! SpaceX needs to think more outside the box. Do a search for a Boeing Patent dated 2015 its number is: US8981261

  • Block 5 in the Falcon heavy 👌👌😍

  • hey, it's Dean Cain...

  • No! Not "Big Falcon Rocket". "Big F*cking Rocket"

  • My comment? Lose the dumb astronaut suit, you'll appear more polished and professional

    • The suit has a long history, and it started as an art project on Instagram. The images have gone viral with millions of views, dozens of front page Reddit posts, and countless news outlets covering the project. So when I started doing US-tv last year, I continued with the suit since it’s been my brand and identity online. The suit is awful and I despise it, but it’s sort of the bane of my existence. I have done a few polls and the overwhelming majority think I should keep the suit, so I do. If you need to know more about it I have a video titled - How a space suit almost killed me us-tv.org/tv/video-B3s7BjU6sDg.html

  • What are the chances of refuelling a stage 1 on the barge and then flying it back to Cape rather than towing it back using a tug.

    • Zero. The barge is already coming back... so fueling it up is just wasted money, besides additional pointless risk.

  • Well done.

  • so so good....I came here after the launch, and I salute your attention to detail!

  • Thanks for the great video. For the first time Rocket science is being done at maximum efficiency. Looking forward to Block 5 human launches and the heart stopping amazing BFR, the first big paradigm shift in human space flight.

  • Also think I recognize that astronaut head shot behind you as Clayton Anderson? I got to meet him and host him at my school when I was in high school. He is awesome and signed my copy of his book!

  • Listen. Where did you get those models. I want every single one haha

  • Where do you get your models

  • Block 5 launch and landing test successful!

  • I know spacex loads fuel and lox just before liftoff, and you can see the venting. I understand the density of the lox dissipates quickly, but what's the danger of the residual combusting?

  • That was great!

  • Did you say BLOCKCHAIN? oh block change, nevermind.

  • Dear Santa...

  • Just make sure you talk about why the block 5 was scrubbed

  • you're the most accessible person regarding the topic. i love you so much.

  • Is it me or your eyes are of different color?:D

  • Bangladesh's first satellite Bangabandhu - 1 will be launched by block V

  • congrats from bangladesh on your 100k subscribers... so falcon 9 block five will make its first fly with our very first satellite bongobondhu -1 ... is it correct or not??

    • That is 100% correct!!! How awesome is that? And thank you 🙏

  • When the lunch Will happen

  • So excited for Block 5 tommorow!

  • Where can I get those rocket models??? My son would LOVE it!

  • Missed opportunity with blockchain joke

  • It's too bad he couldn't land them in the parking lots of various aerospace museums as donations.

  • I dont know why SpaceX needs to launche one rocket for multiple times before puting humen on them but when NASA stars a rocket they just go ahead a launch humen into space (according to what i heard about Trumps plans for the first SLS launch).So I think this is a bit unfair.

  • I love your glasses, where did you get them? :D

  • Just noticed your eyes are different colour

  • Great video thanks Everyday Astonaut

  • It makes perfect sense to use the earlier block models for extreme testing. As you said, those are data points that can provide a list of options in the event something really weird happens on a critical launch. They could even do things like having a grid fin break off during the re-entry burn to see if it is controllable with only three fins. Maybe tumble the booster and see if the attitude jets can recover from a tumble or a spin. Fail more than one engine in an asymmetrical pattern to see how the system adapts.

  • In the video his eyes are different colors

  • It's amazing to me how you only have 110k subscribers. I honestly figured that you would be pushing a million by now. Love your channel, research and information.

  • It has to stay at 12' wide to fit under over passes and under wires for land transport. I wonder if Elon is digging a tunnel as we speak.

  • 1:55 😂😂😂😂😂 7:15 Photo of Gwynne Shotwell and Tim Dodd.

  • The general public doesn't struggle to understand the point of the Block 5 Falcon 9. The general public doesn't know the Block 5 Falcon 9 exists at all. A few know the Falcon 9 name, but that's it.

  • Would it be possible to put 2 more strap on boosters on the falcon heavy?

  • my friend hates you but youre a cool dude :) and also "cheese"

    • Maybe, like me, he(?) has a hard time getting past the dork look wearing a flight suit and helmet ALL THE TIME. I hope you at least wash that thing once in a while.

    • yo but if elon asked you if you wanted to go to mars on a one way trip, would you say yes? and your videos are the best watch them nearly every upload :)

    • Well I’m glad you think so... wonder why your friend hates me. Not sure I hate anyone I don’t know... maybe he doesn’t like the color orange 🤔

  • Can't wait for the BFR! It's gonna be so beautiful to watch it take off! Or explode, either one works!

  • Anyone knows what happens to the second stage after deployment?

  • A “blockbuster” bag of “hot air”

  • Awesome video. Super informative. Keep em coming.

  • Makes sense of a rather confusing subject! SpaceX will sure confound those advocates of version control

  • I would write it as - Falcon 1- Block 1Falcon 9.1- Block 2Falcon 9.2- Block 3 Falcon Heavy- Block 4 Falcon 9 [block 5]- Block 5

  • Humans: We should do the technology age first guys... Elon: N0 w3 d0 sp@c3 @g3 first b0is Public: YAY

  • Where did you get a block 5 model? I'm jealous

  • 2022: remember the old times where they didn't have a spacex launch a day? yeah, what a time to be alive.

  • dude i love that you are so down to earth and you really talk to us as people. you dont try to seem smart you just are. big diff

  • I just saw a comment by Elon referring to f9 block five as version seven, even saying that they should be called version seven

  • they need to start selling advertising on the rockets. like race cars.

  • 1) A little sad at first about the whole white Falcon 9 dying 2) On the other hand, it's a design change makes it unique, like this is a whole new ship that was SpaceX's ultimate goal. Boss mode Falcon 9 if you will

  • Great show, never saw it before. But I'm hooked. Just a bit disappointed that BFR means Big FALCON Rocket. We all thought it was something else! Thanks for the hard work.

  • what do you work??are you a real astronout??

  • And the first Falcon 9 did what is probably the most terrifying roll program in history. Most rockets like to be more than 5 feet off the ground before rolling 90 degrees.

  • I love the colour of block 5 so much! So familiar to the Saturn 5... wait a minute..... Elon I see what you're doing!!

  • land....

  • You asked...Kind of confusing. But thank you for the video.

  • Oh yeah, *L A N D*

  • I wish people would do some videos on Reaction Engines and their Sabre engines, Skylon space plane and their hypersonic passenger plane. It's slow going but come on, SSTO space plane!!

  • I'm looking forward to seeing Block 5 fly.

  • Love Block V, the black represents a refined, efficient design - opening door to greater profits and BFR development, not to mention crew flights. Also, Ive emailed Elon to ask if I can keep an old Block IV if I swim out and collect it, fingers crossed.

  • Why didn't you just call SpaceX and ask?

  • You cleared a lot of things up for me, e.g. SpaceX's plan. Cheers.

  • can i get one piece of tiangong 1,lol

  • Man you know so many juicy deets. Love it!

  • Why are you yelling?. So fuqn annoying!.

  • really enjoyed the video until you went into the stupid "this is how all youtube videos end" bit.

  • music's a bit loud

  • thats some mighty fine kool-aid

  • I wanna build that ;-;

  • laugh at those stupid press reporters XD

  • Hey awesome video, so much work into it! Where can we find the images of the diffent version you show ? They look awesome!

  • Where did you get the falcon 9 models?

  • Very good, clear and self explanatory. Thank you.

  • dude. you rocks.

  • Tim, how could you get the models of Falcon 9?

  • You should try making your spacesuit space-suitable.

  • What are those spinning planet replicas you got behind you on the "edit cam"? Cheers

  • Theres more then rocket engines that have turbo pumps, and yes, they get cracks... although commercial ones have replaceable blades ect rated at longer lifetimes then the minimum time between large maintenance.

  • Vehicles that have something left to land or park aren’t optimised enough, and are carrying excess weight.

  • Hi Tim, Love your channel. On the subject of nose cone/ cowling recovery how much of a stretch would it be to design each half so that when they separate each half is a controllable lifting body that could be glided back to a runway and landed. It looks to me the existing design isnt far away from a lifting body?

  • You scared the poor cat at 7:40! 😂😂😂

  • Great chanel. Great content. Keep it up. :)

  • You are part of the reason that I want to become a aerospace engineer

  • I'm alright with the old Falcons being sacrificed to R&D. The all-white paint scheme was nice for the first launch but the scorching from re-entry exhaust kind of ruins the aesthetic! I think the new black/white scheme will look great. I presume the black has to serve some purpose and isn't purely aesthetic.

  • I'm totes looking forward to seeing B5s fly over and over and over...!

  • What scale are the models that are seen in the background?

    • Everyday Astronaut About how tall is it? On Buzz Space Models, the 1/144 scale is around 45cm tall. The 1/72 scale is around 1 meter tall.

    • I want to say like 1/70th ish maybe?...

  • Jeff who?

  • Or the explosion on the pad was caused by a streaking ufo from right to left. You can see it in the vid on here.

  • Where did you purchase the falcon heavy model?! 🤔
