Why does SpaceX keep changing the BFR? The evolution of BFR
ฝัง
- เผยแพร่เมื่อ 19 ก.ย. 2018
- Elon Musk updated the world with the plans for SpaceX's BFR at SpaceX HQ in Hawthorne. I attended to learn about all the new exciting changes! For now, we're going to just look at what has changed with the vehicle over the years and why it keeps changing. Later we'll do more in depth videos about Yusaku Maezawa's beautiful #dearmoon project and the weird reentry system of the new BFR!
Follow up video: Why SpaceX's BFS will fall like a skydiver and not fly like an airplane - • Why SpaceX’s Starship ...

Once more thank you for being the only one with a contributing question. And not just asking in 10 different ways how much Yusaku Maezawa paid
Exactly!!
Very true
Just highlights again the click-baity nature of news reporting, $$$ make the headlines unfortunately. Tim rose above all that nasty business!
This!
That last one was a little funny...asking for a percentage, l Iike they could sneak that past them and not know that Elon and MZ wouldn't know they could do the math
Thanks for focusing so much on the designs, and Cool to see Elon reacting so good when you asked that question!
When world's collide.
Make a replica of the marble machine and send it to mars😀
Well, what brings you here?!!
@@deadliner178 engineering obvs. Wintergatan is music engr
Woah u r here epic!
Tim asking the best question at the event. Seemed like the only one Elon was interested in! Good work!
Ya I thought that was great, and thought way to go, mate!
Elon said to tim that he love talking to him
13:30 "and framing that question with precision was very difficult"
...
**robot turn**
Hahaha yes! I noticed that too!!!
Yeah true
Ruined the 69 likes
Oh wow this is very old
@@AidenHere Thanks for reminding me of this lmao
hey tim, when you asked elon about the question he seemed like his expression brighten cuz everyone else was talking about things that i think elon is bored about, so you probably did something good for his mentality a bit.
BLUE asian I saw that too... good 👂
Noticed it too, he lights up a lot when he hears the question because it is about the design and technology/engineering instead of the boring stuff like "but how much money is he paying you to do this?". Those type of questions are clearly not what Elon are looking for at these events(hint hint: Tesla stockholder conference calls). Elon Musk enjoys talking about the engineering of it all but most people do not have the mind to grasp that stuff so he rarely get to talk about it in Q&A's.
he also lights up when he calls people child rapists
Sean Bean
Stimor, and then Wins the Lawsuit!!!
I just realized- This is the first real rocket to actually land on its fins like they always do in SciFi :D
Who knew TinTin, Wallace and Gromit, and Abbott and Costello had it right
And Werner Von Braun!
Von Braun was an absolute legend.
Is just another hint that Time Travel will happen in 2036.
Jeff Vader - He was a nazi but ok. In terms of rockets, yes. Otherwise a big douche.
The fact that SpaceX is giving so much insight into their design decisions is (at least to me) another proof, that the main objective of Elon is just to move mankind forward and actively encouraging other companies to join the space race, while at the same time he has a huge amount of faith in his team that, at the end of the day, they will come out on top.
It has been so cool when you got to ask that question, thank you so much Tim. Greetings from Argentina!
Cuantas copas tenes?
Less cool that he didn't get an answer...
¿Para beber? Soy estudiante de ingeniería, no me dan copas por aprobar materias (lamentablemente ☹️). ¿Vos que haces?
He did get an answer...
Okay, not in the video he didn't, is there a way I can actually hear the answer?
You could say that the raptor is really raising the bar...
I’ll see myself out.
And I’ll shut the door behind you. 👎
Elon woud love this pun
Ryan Clark Come on man, this isn’t easy. There’s just so much pressure...
With Queen and David Bowie Under Pressure in the background.
LMAO
Hey Tim,
Great job on this video! We were all proud of you when you asked Elon a question!
Yeah I was sorta getting bored with the "hOw MUch Is He PAYing" questions, when I heard Tim speak I was super excited, I kinda felt happy for him, amazing how far he has come, a 1 on 1 q&a session with elon would be great!

So how much longer before Elon offers Tim a role as PR / Education manager for every stream etc etc. I mean, having Tim in the live stream explaining what they are doing for every launch and explain the design changes and so on. You really want a guy that loves talk about his passion. Of course, best would be Elon on every stream and be technical to the deep end. But he has enough on his plate for sure! Upvote for the idea as Tim for a possible PR manager/face for streams and such!
Tim, being good at TH-cam, MIGHT make more money than Elon could offer him
@@poopscoopproductions3177 he probably won't make more money with TH-cam until he gets at least 5 million subs. Which let's be honest he deserves it with all the high quality content
The moment i heard you asking your question live I couldn't believe it. He even complimented you, that was my favorite part!
If you ever sit down with Elon Musk ask him only the technical questions. We're all nerds behind the screen remember?
Not just technical, some of us are interested in the design philosophy behind it too!
@@Hirosjimma yea but that comes after the design
Aaaaaand I got the 69th like
Yeah
@@crimson4253 Are you in MTV? lol
I watched the announcement live, you definately were the only one to ask an intelligent question.
Love your passion, subscribed.
I would like to honestly say thank you for this channel, all the news these days it so negitive, but this channel manages to find some posistive news that gives me a little hope in humanity.
Agreed... Definitely need some positive news
The world is even crazier now. I'm so happy I found this channel.
Tim, when you asked one of the only meaningful questions in the BFR conference the other day - I just want you to know (from the comfort of my couch) I gave you a virtual nerd fist bump. Good God, why do they let some of those reporters in there?!!?!? Who the hell cares how much he paid?! Tell us about the design changes! tell us about how you have managed to achieve 300 bar/higher! Either way; Another great video, man!
Definitely, re: virtual nerd fist bump. Clearly Elon felt the same way; he instantly brightened up and answered it enthusiastically.
Re: very poor average quality of questions - this is particularly bad with US-based media I find (I mean, surely I'm not the only one that noticed a difference between the US and Japanese reporters there, right?). Completely obsessed with money. It's like they use it as a proxy for respect/importance/power. Maybe they really do 😫 I'm not sure. And it's not like it's all the media's fault; if there wasn't a market for that "content", they wouldn't produce it. Clearly the consumers value it more than quality reporting. Man, that's depressing.
(For an extremely clear picture of this, look at election media from the US versus other countries. It's dramatically different. Much less emphasis on spending and other money-related matters, fewer soundbites, more detailed reporting)
LagLawyer Well actually quite a few people care about how much she paid. It’s only natural.
*he
@ 8:34, the grin on Elon's face showed how happy he was when he got a cool question to be answered
In Australian parlance, you are a deadset legend! That question to Musk was devastating. Bloody great work!
8:57 I didn't even notice that you have different eyes colors until now hahaha
Why did they keep changing the Falcon 9?... it needed perfecting! The closer to production the more issues are discovered with any design, which need to be solved.
Also, there's so much talk about "Elon Time", and SpaceX delays... but no comments about SLS, James Web and any number of other projects that are also delayed way more than SpaceX. Space is hard people!
There are lots of talk about SLS, Webb and so on, but they are a completely different type of project. The SLS design has been frozen for a long time, but still hasn't flown. With that in mind, it's quite puzzling that they are still making such major design changes to BFR, a launch vehicle which is supposedly going to fly in less than 4 years. Personally, I think the BFR stack will probably get major delays, and NASA's EM-1 and EM-2 will probably overtake it.
If it flies and keeps the performance now promised (the payload to LEO dropped from 150 to 100 tons from 2017) it will still be an impressive vehicle. I just hope it will be used for more than shooting artists into space.
Not to dis NASA or it's hardworking engineers but SLS is a complete joke. It's just a newer Saturn 5 with an insane 1 billion dollar price tag per launch with zero reusability. NASA should focus on science exploration like rovers and the james webb and leave the rocket building to companies like SpaceX.
‘Rocket time’ is pretty much the same deal as ‘Elon time’: ever the optimistic.
Media :(
1. SLS isn't a Saturn V. It is a new design based on existing Shuttle and Delta IV components. Reusability doesn't matter when you are only doing a few launches a year. But I agree, the biggest problem with SLS is the cost, which is partly because Congress have forced NASA to adapt a compromised design focused more on keeping jobs than actually making a launch vehicle (which is mainly the secondary purpose, sadly.) But it is probably going to work just fine due to it's conservative design, and will still be the most powerful rocket in the world when it flies.
You got to speak to musk! Good eye!
Edit: Didn't know you had heterochromia!
Me to
I genuinely had no idea either, but now I do I definetly need some bowie cosplay from Tim
Yeah me neither. He said it and i paused just to make sure and now he's cooler than ever!!!!
Same here, I had no idea!
IneptOrange haha
Elon: "A Good Eye"
Omg the lord has spoken to me.
I think the 2016 ITS looks the coolest; it's got this weird sci-fi aesthetic.
Nah man, it's not sweaty and shiny enough.
Exactly
You can tell it’s designed by space-x, the new ones are mostly designed by nasa.
@@psych5581 the latest BFR looks ugly compared to the first concept
Yeah, but that's how you know the latest ones were designed by actual engineers, and not concept artists.
Everyday Astronaut for #Dearmoon. Who's with me? I mean, he's got space knowledge, he's a vlogger/filmmaker, he makes music, AND he's talked about spacex for years. The creative works he'd make after (or during) the Dearmoon mission would be amazing.
Yeah we need to send tim dodd to the moon
& photographer
But we need to bring him back safely too 😃
LETS DO IT
Tim Dodd, the actual astronaut
Love the rundown! A few interesting things:
- Elon mentioned that the AFT cargo bays can be switched for vacuum engines. This means that SpaceX can focus on streamlining the BFR without having to design it from scratch later. Vacuum engines are good for increasing mass to orbit, so they probably figured out that 100 tons are good enough at first. When the vacuum engines are switched in, we will see far more than a "mere" 100 ton LEO launch capability.
- The AFT cargo bays are great for storing Starlink satellites. This means that SpaceX can run launches for customers while sending their own satellites up AT THE SAME TIME! Again, they probably don't need vacuum engines to do this, so it's a really clever solution.
- Considering the points above, we will probably see two (or more?) versions of BFR in the future: A version with sea level engines only and a vacuum version. The sea level version will be great for Starlink/light duty delivery and personnel delivery/tourism; especially point-to-point flights on Earth. The main BFS could carry passengers, while AFT cargo could carry trade-goods. The vacuum version will be great for heavy duty hauls (like new space stations) and long hauls to other places in the solar system.
can't wait for that kind of flight to be reality... maybe even in the style of the Expanse universe... shuttle from port Lunar base bigger ship (presume BFR) transit to planetary bodies or stations...
I think Tim is right that the designers and engineers have sacrificed payload capacity for payload _volume_. The Raptors are now more powerful than they were for the 2017 design so I suspect that if the '2018' Raptors were put on the 2017 BFS that payload capacity may well exceed 150t, but now that the BFS has more and larger stabilisers and more payload volume, it means the capacity has dropped because the dry weight is higher.
It also means, as you said, SpaceX can focus on getting the BFR operational on one engine design and come back later to optimise it. Tanker BFS's will probably retain the sea-level engines, while cargo and crew BFS's will shift to a mixed set.
SpaceX is also clearly targeting the BFS to service NASA's plans for both the (ill-advised) LOP-G and Lunar services in general. The mental image of a BFS with 1000m^3 of habitable space docking with the LOP-G with ~125m^3 of habitable space amuses me greatly.
I don't even wanna know what that thing (the LOP-G) is gonna cost riding on the biggest Pork Barrel ever created
"Why not stick on a hyper-drive, or a worm-hole engine, or an anti-matter warp drive while you're at it?"
Probably because unlike rocket engines (both 'sea level' and vacuum), carbon fibre composites, radar guidance, computer-control, and hydraulics, those don't exist.
"You fanboys are a hoot. Zero, and I mean zero scientific understanding, and close to zero common sense."
We know that rockets work. We know that SpaceX's F9 rockets in particular work. The BFR is fundamentally a problem of scale.
"a blatant con-man as Musk"
Oh, there it is.
TheOneWhoMightBe Lol. That last part is so true. Elon’s haters all try to use science to defend themselves but it’s all just a screen to hide that their entire basis for hating Elon is a personal issue, not an objective one.
I HAD NO IDEA HIS EYES ARE DIFFERENT COLOURS!!!! heterochromia?
I have homochromia :(
I have homophobia

I had sexual relations with someone called Mia
I have Osteoporosis
By the way I learned of you by watching the live stream and you could tell Elon appreciated it. You have a new sub bro. Thanks for making space great dude.
Exciting things happening in the spaceflight industry
Finally.
Exciting things happening space flight, war going on in Asia, crazyness on college campuses, it's the 1960s all over again!
only because SpaceX!!
Tim, you are the best! Thanks for your job and hi from Ukraine!
and me!
The good eye pun made me spill my coffe ;) Cheers TIM, Love Your work!
Same. I literally Laughed. Out. Loud...
Not a pun but still funny
Nice channel! You showed up in recommended probably from watching other SpaceX videos and I thought it was really cool that you were the one who asked the only REAL question! Liked & subscribed!
Great video Tim! I finally gave in and jumped on Patreon. The quality of your videos, the info you provide and how much I look forward to your content; I just couldn't excuse myself anymore for not helping you out in some small way. I'm actually planning to be at the SAOCOM 1A launch this coming October. If you're gonna be there, let us know so we can stop by to say hi. Keep up the great work!
Thank you so much! That truly means a lot!!!
I like how the new BFR kinda looks like the Spaceship from Futurama. :D
As always Tim, great Video!
Thanks for giving lay people a peek into the engineering feats of space travel. Your enthusiasm is infectious!

That still cracks me up.
TBH I sub'd ages ago but I didn't take you very serious w/ the jumpsuit thing, and figured you must have a (hmmm...) more 'grade school' target demographic. I figure I should stop by and reassess my assumptions after the respectable question that went over my head during an international Space X press conference. I think I may have mixed up my wires here. Nice set, nice upload, nice job. I guess I've been missing out on some good content. This is worth seeking out on the sub feed at a minimum ;)
Thx for the wake up call.

Woah! Thank you!!! That means so much!!! To be honest I try and produce content for everyone but really do want to focus on family friendly. But that means a lot. I do take it all very seriously, so thank you for re-evaluating!!!

I love everything about this channel from the content to the Hi-res video quality. Amazing work!
When I heard your question on the SpaceX conference i subscribed to your channel and turned on the bell so i could see your videos about it.
Really love this channel Tim, I love how it just keeps getting better, great content, edits shooting is really top notch. From one completely unrelated channel to another, I genuinely love your authenticity and connection with the audience. Well done mate
been trying to find a channel that highlights everything space related. awesome to stumble upon your channel! love the videos so far! thank you for the creativity and information
I wish Elon Musk would have addressed your question about the launch abort system.
Bradley Graham he had to keep to his script... the guy is a frontman
its bad commercial to talk about failures
There will almost certainly not be a launch abort system.
I noticed that sneaky audio correction at @6:48 XD
Whooaaaa if you never said that you had different colored eyes, I dont think I ever would have noticed. Super cool though. Thanks for the great question to Elon and thanks for your videos!
Great vid, Tim! My wife and I laughed out loud at the "good eye" part. I am very happy you are there to help all of us non engineers get some great answers to questions.
I am impressed, you have gone from a bit silly (in a positive way) youtube space show, to be one of the premie space journalist, you should try to interview Jeff Bezos next ;)
I have a theory on why the 7 sea level raptors on BFS: It‘s for testing reasons so it can launch all on it‘s own with a high fuel load and do the high altitude hypersonic TestFlights Elon talked about without requiring the booster to get it there.
Human Person: I never thought of that! Good catch.
Good theory!
he said that they will develop vacuum engines too which will increase the payload capability to mars by a lot (this should the capability for LEO aswell) I hope they willl push this configuration sooner than later after initial suborbital testing is done, no vacuum engins for an upper stage is pretty senseless
You're literally the best in this business, Tim. I am an extreme fan of yours and TMRO's. Bid you good luck to bring up more exciting stuff in future. And my God, that studio's amazing!
Awesome videos. I love pretty much EVERYTHING space!!
Well done Tim - Double Win!
Best live question
Best post summary
It is so frustrating how during the press event the most common question was about cost. Here are 2 visionary men, one who is taking on the task of making us a multi-planetary species and making us dream about space, the other one is risking his life for this voyage. How awe-inspiring isn't that ? I got goosebumps, but only thing the mainstream press is asking about is cost and money. WHO CARES WHAT HE PAID???? the man is going to the ACTUAL MOON, fulfilling his and others dreams. Of all the hundreds if not thoushands of possible questions they are wasting the time asking about cost like 4 times ?! WHAAAAT THE HEEELLL. What happened to inspiring people to dream about a better tomorrow ??
@@javaman4584 Typically reporters don't subscribe to Socialist/Communist ideology. It's bad for business. You're making a false equivalence.
And most people don't have the knowlege of Space flight and its history to understand that even if this isn't immediately impactful for the common man, the long term results from this will inspire more people to get into STEM which directly benefits everyone.
I understand where they are coming from, but as is unfortunately often the case, they simply don't know what they're talking about in regards to this subject. Which is quite normal for average people. Hopefully #Dearmoon can help to change that.
But it in no way means that their underlying philosophy is faulty. Helping those in lower income brackets also majorly contributes to STEM by raising peoples abilities to pursue their interests.
Harambe's Ghost - The reporters are smart, smart enough to know they need to appeal to those of way-below-average intelligence
@@javaman4584 WTF, no. They're making offerings to the all-pervasive US religion of money. They're trying to figure out how important the guy is, by means of the cost he paid - it's a proxy value for respect deserved, in the religion.
Because vision gets you to the moon. Cost/benefit lets you stay on the moon.
Vision lets your space program survive 1 or 2 mission where everyone dies in a space accident (Space exploration is dangerous). Cost/profit allows your space program to survive when 14% of the mission result in death.
Martin Lööf the shareholders, don’t be silly price is a very important question

Hi Tim @Everyday Astronaut
Important to note: the fins give drag, but not much compared to the hull. Their real purpose is stabilization and maneouvering. Just as Elon said, it's like a skydiver (very good comparison). Moving them "upwards" or to the "vertical" (rearwards in direction of flight), makes them give less drag and provide natural static stability on roll axis.
If the vehicle rollsto a side, that side's fin and cannard get more perpendicular to airflow, having more drag and making the vessel roll back to 0.
For pitching up, cannards can be put more horizontally and/or rear fins more vertically to make the nose more draggy than the tail, the opposite for pitching down.
For yawing, left cannard and right fin can be moved opposite to right cannard and left fin, deflecting air more to one side than to the other.
Also, all four surfaces can be moved to provide more or less drag and control the downrange distance.
It's a neat flight control system that can perform all those corrections without using RCS. It's awesome!
Thanks for asking Elon a technical question among the typical reporters' questions. By the way, if I asked about the money... I don't care at all about how much did he pay! I prefer to know how much will I need to pay, ho knows... 15 or 20 years from now?
Regards.
Tim, honestly I believe you can over qualify for an awesome job at SpaceX. Thank you for your inspiring insights
Liked and subscribed! I love your work and the way you focus on the science stuff!
Very impressed by your analysis, thank you.
Fantastic video! I The moment I heard your voice in the Q&A I trow my hands in the air and shouted "YES!". It was that exciting. It also convinced me to support you Patreon.
One thing to note: in 10:07 you compare the SL Isp of SL Raptor with the Vacuum Isp of Vacuum Raptor. Which is not a valid comparison.
how much did your space ship/studio cost? :) seriously though. it was sad to see those reporters make fools of themselves that night
Like ever, that's the very reason the man himself proposed Pravduh, duh
Probably greenscreened.
Imo your best piece yet.
The engineering process discussions are some of my favorite items!
Love your channel and the technical and historical focus of it. Like you, I crave BFR/starship details as they emerge. I’m sure I’m not the only person that would enjoy more BFR content, even if it’s just discussing current reddit theories and potential tech hurdles! Looking forward to the next one

Very good commentary. The engineering is so creative the mind boggles.
You are kind of a musician right?
Go ask Yusaku if you can fly with him to the moon!
not kind of. he IS.
but he would be too old to fly (theory age by then, 40-50s) my guess of the theoretical max age for space is bout 20-30s
AsHalt - John Glenn was 77 when he went back up on the shuttle in 1998. As long as you can pass the physical and do the training, there's no "maximum" age. en.wikipedia.org/wiki/John_Glenn#Return_to_space

Ummm, there's no age limit on a government vehicle when you also happen to be a US Senator.
Love your passion, Tim. Congrats on your success and continued growth of your channel, access, and exceeding your aspirations going forward.
One of your best videos from the “science communicator” standpoint. Well done sir!
Wait... I just happened to come across your channel and you're Joe Scott's friend. Good video, you have a new sub.
seen you before in recommended. And this video appealed to my nerdy, electronics, Net eng, fire control self. (ex-navy) Thank you for the detailed info.
Just wanted to say that "The Scale Of It All" is a great track, and that I had no idea that you made music as well as being an amazing science communicator. Great work!
Thank you Tim for the great reporting you do, Keep up the great work. Getting Humans Off this hunk of rock will take alot of Work.
People let's flood Elon's Twitter account asking him for an interview with Tim #dearmoon #TiminSuit
5 years later, starship has launched and now only a few days away from the second launch of this beast of a vehicle (this comment was made 11/14/23)
yeah it's amazing, obviously IFT2 was a success, just imagine we told that tim 5 years ago 💥
hey tim, I saw you live when the spacex conference aired and felt like we all were there with you asking elon and maezawa questions. thank you for your work, I think that you will be rewarded in the long term, like traveling to space in significant missions and so on (I know you will think this is probably not gonna happen but I believe it certainly will. Keep doing your magic and thanks for everything. big hug from andalusia
Love your vid's man. Keep it up
Let's go Tim!! Can't wait for that Reddit Q&A ft. Elon
Who likes the old version better? My self I prefer the newer one...
I'll vote for any rocket that looks like Destination Moon/Tintin/A Grand Day Out.
I like myself
2016 ITS looked the best imo
It's not about look. But when you ask like that: The new one is ugly, the first one is epic
I refer the oldest look
That eye joke was hilarious, major props for that. I like ur videos.
great job on this vid. Very fun and informative.
I never noticed his eyes up until now. Wow.
Well done Tim. Best of luck getting that interview with Elon! He has a fondness for “today’s” media, TH-cam, so you have that going for you!
Bring a baggie of weed, and youre in...
or a nice bottle of whiskey? I suppose people like nice things! who woulda thought, huh?
great camera and editing work! i'm very impressed with the shots you guys got considering you're not the official spaceX camera crew. keep it up
You are extremely good at what you do. Thanks for everything.
I didn't even know you had different coloured eyes until you said it
2nd design was my favorite.
so fantastic work, we support, it grows!
Really well made and super interesting
Can you make a table with all the spec comparisons?
The idea is to see how the BFR evolved, specification wise.
- Total height
- Booster height
- Spaceship height
- thrust
- number of engines
- cargo capability
- pressurized living area
- cabins
- Max amount of people
- any other specification that you can think of.
Thanks!!
A BFR development tracker on the everyday astronaut website would be super cool..
good idea. meaybe you can do it
maybe make it a google doc
Maybe Eventually they want to achieve something like Starship Enterprise..!
I guess?
1:55 The foreshadowing is absolute perfection. Congrats on your trip to the moon, Tim!
Amazing presentation!! Thank you!!!
So you and Elon are like besties now, yeah? :D
Musk being involved in a long-form interview by yourself and Scott Manley would be nerd christmas. Lets make this happen.
The brand new design just looks a hell of a lot cooler and more science fictiony.
Modern rockets will converge towards a Tin-Tin style of rocket design ;)
I think it looks a bit more natural, almost dolphin like!
Tim's enthusiasm is infectious!
Fantastic video..... thanks for posting
I came up with Elon's follow up to the BFR
Take three BFR, and put them side by side like the Falcon Heavy. Then put a full BFR on the center core.
The Stupid Falcon Rocket
or you can attach falcon 9 boosters to the side to aid in extra bigger payload
BFR Heavy
@@squdardt.9719 😂😂😂
Imagine the BFR popping a space station (or several modules) into orbit.
And I don't mean it being carried in the BFS shuttle-style, I mean Skylab-style, where the module is plopped on top of the BFR.
The latest proposed design of the BFR actually has a larger pressurised volume than the ISS (1000m^3 versus 953m^3). It basically is a space station.
If they could modify the design (remove wings, as reentry not needed, have the nose cone pop off or something once aerodynamics are not needed), and dock two of them together, it would create a truly massive space station. And for a fraction of the cost of the ISS.
Furthermore, picture an inflatable station module with the "packed" size being that of the BFR's max fairing capacity.
@@aussie_boosh That could actually work... You should reach out to Elon Musk and suggest that he create the first privately owned/launched space station, and maybe if he could figure out how to dock 4 of them together, he could make the first ever space hotel... and maybe either the station or the hotel could be a checkpoint for BFR's headed to other planets. And this isn't a joke, I mean this seriously.
@@levisabin3047
that'd be sick!
@@levisabin3047, the technology does indeed exist for this to happen. Bigalow Aerospace has an expandable habitat attached to the ISS which was carried into orbit by a Falcon 9. They also have had a couple of units in orbit by themselves.
One word to describe this. Inspiring!
GREAT Work, INSIGHTFUL Questions, BRILLIANT Energy&Attitude, INSPIRING What your have accomplished !!!
This new BFR reminds me of mid 20th century scifi rocket designs wear the rockets would ALWAYS land on their fins.
Really makes you think, were they onto something?
Hey Tim, what did you think when he talked about the MegaNewtons of force needed to actuate the wing/flap/breaks ? What kind of mechanism could provide such power?
hydraulics.
The beefiest hydraulics in aeronautical history.
@@Gibson99 yeah of course best weight /power ratio, but the joints are without any visible hydraulics... Maybe it's internal, or transmitted through a gear...
would have to be a gear, i think. greater range of motion that way, and also possible to have reduction gears for greater mechanical advantage and less need for massive hydraulics. granted, you trade speed for torque but torque is way more important here.
They'd need to make a very frictionless gear system if the want it to be rapidly reusable. I'm not a particularly big fan of large moving parts on spacecraft, they pose a much higher risk than static lifting surfaces. Case in point, Virgin Galactics' SpaceShipTwo.
Great job Tim!!!
Love these videos, and love what you do!!
