Simon,
1) SLS stands for Space Launch System (not Shuttle).
2) the space vehicules are not carried loaded with fuel, they are fueled at destination (on the pad) since they are more often than not fueled with cryogenic liquids which would have time to boil off by the time they get to the pad. The only exception are the solid fuel boosters, which were on the Shuttle missions, and will be on the SLS missions too (and probably others too).
I bet you’re fun at parties
@@ryanf1425 Almost as much fun as being wrong in an informational video.
@@sammorgan31 this is infotainment. It is t supposed to be 100% accurate all the time.
@@MySkybreaker but it helps considering Simon is increasing becoming a primary source of information 😁
@@MySkybreaker Its supposed to be accurate when stating facts. The tainment part is the funny comparisons and jokes but the facts should be correct when possible.
Seriously... do bagger 293. It is the largest land vehicle ever, a true monster. It is entirely electric, powered by the power plant it mines coal for. It is crazy!
Agree!
yea lets get this comment noticed i wanna see that
the crawler with the Saturn 5 on top has a heigt of 118 m.
The Bagger itself has a heigt of 96 m. Just to give you all a comparison. Two Saturn 5 Rockets lying successively are _5 meters shorter than the Bagger is in length._ The weight of this bagger is way higher than both Crawlers combined.
@@Craftlngo Lets face it, excavation machinery just cannot beat out NASA engineering. At almost 60 years old, this stuff is really built to last.
Just saw Bagger 293 on Wikipedia, truly amazing....
The Apollo rockets and the Spaceshuttle didn't contain the fuel/oxygen when they were driven to the launch pad. Only SRBs were fueled.
Thanks for clarifying.
Only on "Thunderbirds" did they move a fully fueled - and manned - rocket.
Kind of weird to call the SRBs fueled...
@@turbosix The fuel was poured in long before the SRBs were assembled and hooked up to an external tank.
@@AllanFolm yes, I know. They're solid fuel. They don't come unfueled. It's irrelevant.
The ALCO engines on the crawlers were made by the same company that made the Big Boy steam locomotives. Another Megaprojects that was done due to an enormous number of requests.
at marshall space flight center there is a pumphouse that supplies water to test stand 4670 (originally built to test Saturn V first stage). That pumphouse has 13 ALCO engines, each driving a centrifugal pump. The underground line between the pumphouse and the stand is 96" diameter and system will supply around 300, 000 GPM of water flow.
Both machines have earned MY respect.
steve
the crawler transporters were re engined with the alco 251's . they were originally powered by 4 of the avs-1790 engines. a supercharged v-12 petrol engine, fule consumption was measured by gallons to the foot travelled.
The AlCO engine would make a good mega project
@@thesphinx336 it's ALCo... American Locomotive Company
This episode carries a lot of weight.
Just like my knees
Ha :) that's awesome.
BADABUMBUM TSCHHHHH!!!!
Ugh.
It's pretty heavy
Next, do the Vehicle Assembly Building and the Space Station Processing Facility
VAB is built to withstand category 5 Hurricanes.....there are some photos on internet when it was being built and the amount of piles driven and the structural steel is amazing.I was lucky enough to get an inside tour in 1969 ....it is awesome inside
@@Laura-wc5xt neat
Space nerds
Seconded!!
Bro the VAB would be awesome to see
Questions I literally never thought to ask: "What's the diameter of the steering wheel on the CT?"
Simon: "15 cm"
"Fascinating! Tell me more!"
Yes, 15 cm is using globally recocgnised SI units, not cave-man units, it is round with it's circumference related to its diameter via mulitplying the latter by Pi. It is black in colour and appears to be made to a thermoplastic related to urea-formalehyde/Bakelite.
And the steering wheel have marks every 18º
The fact that it doesn't have a massive ship wheel is disappointing
Great Video Simon - I remember being on a NASA bus tour the day after a space shuttle launch. In the early 80’s, tour busses would drive you out to one of the pads for a view. Being quite young, i don't remember much of the launch tower part of the tour, but I have a clear recollection of driving past one of these crawlers as it made it’s empty return drive from the pad. It filled the entire view, darkening every window on one side of the bus as we passed by. I pressed my head against the glass trying to see up to the top, but it was too tall. I watched as workers high above walking back and forth on cat-walks in sheer amazement at the size of the massive moving giant. Like the assembly building, images and video cannot properly convey the true scale of some of NASAs big toys.
What a cool experience! If I got to be that close to it even today I'm sure it would make me feel just like a little kid again in awe and amazement.
Arrived in Orlando May 7 1992, watched the first launch of shuttle Endeavour, viewing from the parking lot of the hotel, just awesome. Couple of days later visited Kennedy Space Centre and took the bus tour to the launch pad. The crawler was on its way back, words can't describe the sheer scale of the thing. The tour guide gave details but the sheer scale of the numbers he gave were so big as to be almost unbelievable. Also at that time they had a Saturn 5 laid out beside the VAB. Again just mind boggling size, walking from the tip of the tower to the rocket exhausts at the rear,past all the different stages which were separated. And then realising that the only thing that came back was the weeny little re entry module. Rocket stages I believe either fell into the ocean or burned up,not like todays reusable tech.
10:39 Space Launch System!
Don't get me wrong, I love Shuttles and Shuttle based lifters, but the SLS is the Space Launch System and no Shuttle...
@Captain Ron This is not the point^^
I also belive that the SLS will be the last NASA rocket and they maybe should considder switching their development system, since the concept of the SLS is as old as the STS and the development system isn't flexible for innovation or redesign.
@Captain Ron he's correcting Simon, not arguing the merits of the system.
@@emmata98 it quite literally is a shuttle just with engine upgrades.
@@nolancain8792 IF the starship system delivers as it says it will (I am an engineer, and some of their plans beyond "get it off the ground" sound quite dubious to me) there will still be a place for government-operated launch vehicles, specifically for trajectories that would be absolutely cost prohibitive for a reusable craft. Howard Taylor coined a new turn on an old phrase that I think applies: "any sufficiently advanced technology is indistinguishable from a Really Big Gun". It would be wise to keep that in mind as well before allowing certain technologies to be allowed to operate by private companies rather than government entities.
But yeah, SLS is 10 gallons of compromise in a 5 gallon hat.
@@nolancain8792 it is more a sidegrade.
Also the whole orbiter is missing and the cross range capability, the cargo capability back to earth is missing, ...
Great video but a few points; SLS stands for space launch system, not shuttle, and vehicles aren’t fully fuelled in the VAB, liquid propellants are loaded at the pad for safety
and weight reduction for sure....
The space shuttle official nickname was STS (Space Transportation System).
suggestion - moving the Cape Hatteras Lighthouse, saving this thing was a pretty amazing feat of engineering. In the first 50-60 years after it was built the ocean eroded away the beach until the tower was in danger of collapsing into the ocean. People started trying to save it in the 1930s by attempting to curtail the erosion, but with little success. In 1999 they moved the 5000 ton, 200 ft (~61m) tall tower 2900 ft (~884m) away from the beach over a period of like 200 days. ALSO, they recreated the original site with ridiculous detail by placing the original buildings and the lighthouse in their same orientations and even relative elevations. The whole thing was somewhat controversial, with some locals fearing it would be destroyed or just complaining that it was somehow disrespecting the history of the lighthouse (although I think a pile of bricks in the Atlantic Ocean would be pretty disrespectful to it's history as well).
Unfortunately now that the lighthouse has been moved, the ground that were built in response to the erosion are no longer maintained, which will eventually lead to the famous surf break from being as magical.
PBS Nova did it already.
@@BinkyBorky a lot of people have done a lot of the shit on this channel...
I went up in 1997. So many steps...
The view was worth it though.
My first time up the Lighthouse was in 1997. I used to go to the OBX every summer for the next 4 to 5 years. I saw it bring moved, however have yet to go up now that it is has moved. Kind of sad that it is no longer right on the beach, the view from up there along the beach was incredible.
While built by Marion, the original design came from the engineering team at Bucyrus Erie (same guys who built Big Muskie). When NASA asked for a design they didn't share that they would then take the design and share it with the other bidders. Bucyrus of course put the design cost into their bid and lost to Marion who didn't have to spend much to finalize the design.
ironically, Marion's cost ended up to be over the amount of Bucyrus proposal. A second major factor in Marion's favor, besides its considerably lower bid, was its announced intention of choosing a project manager from its own personnel, thus saving considerable time in building a team. Bucyrus had said it would bring in one from outside. Having received the contract, Marion selected a competent manager, not from its own company, but from - of all firms - Bucyrus-Erie.
This story has been circulated for years and it's false. While Bucyrus was approached first by NASA, both Marion and BE had their own design proposals. Bucyrus would not have completed a design before being awarded the contract, they only had a concept which is typical for the quoting phase. After the contract was awarded to Marion the crawler was designed by Marion engineers. I worked with many of the engineers who worked on this at Marion and this was indeed a Marion design. Suggesting that the Marion Power Shovel shop would build a machine designed by Bucyrus is as crazy as suggesting the GM would build a Ford designed vehicle.
@@bc1969214 However, the Project Engineer was a longtime Marion employee. Years after the crawlers were deigned, NASA honored the Marion Project Engineer and the Marion Power Shovel company as the designers of these crawlers.
@@stevegilmore6011 thanks Steve, I found some detail that I posted from the NASA pub titled Moonport (good read, free online).
The VAB is its own Megaproject episode.
This! Mentioning the VAB and not making a video about it would just be cruel.
Ironically, the original roller bearings suffered failure due to side loading and it was noticed by finding pieces of them on the road bed. Engineers then went to using Bronze bushings as they were able to handle the side load pressure better than a roller bearing. As far as the upgrade to new Roller Bearings, I am not aware of the current upgrade specifics. My information came from a NASA site I found in 2008 or so. hope this helps, Paul in Orlando Florida
You should cover the Marion 6360 “The Captain”
Or Big Muskie
Both were made in a race to build the biggest mining machine
The Marion power shovel company helped build the NASA crawlers and while doing that they also built the largest power shovel ever built
The Marion 6360 “The Captain”
But they were in a rivalry with Bucyrus Erie and in 1969
Bucyrus won the race after the completion of the largest Walking Dragline ever built
The largest single bucket digging machine ever built
The largest walking machine ever built
And the largest mobile machine at the time
The Bucyrus Erie 4250W “Big Muskie”
Both machines I think deserve to be covered on this channel
Also at 4:14 that big Brutus the Bucyrus Erie 1850b
He’s the last stripping shovel left on earth
He’s on display in Kansas
There were bigger ones built but none survived except Brutus
I’ve been to the museum twice
I love going inside the machine
Absolutely, I've suggested these before. You could also include the Bagger 293/Bagger 288 if you want to get the memelords/Ghost Rider fans in on it.
It's a shame The Silver Spade wasn't preserved.
BAGGER 288, BAGGER 288
You can tell you really have a passion for those machines. I wish I was that passionate about anything! I have almost no idea what you are talking about, but you have made me want to go visit these machines my self now! Lol
yes
I also got to see this up close as well. One fact that you can include is that it maintained the Saturn V and support tower to within 1/60 of a degree of perfectly vertical.
I remember years ago watching an episode of modern Marvels about grease and one of these crawlers was featured in a segment where they showed a crew literally digging out buckets worth of old dirty grease so they could replace it. The whole episode was amazing showing how even some of the most amazing things we have built still cant go anywhere without the right grease to keep it moving. I love learning about these amazing machines
I don’t know why you thought this would be boring. It was pretty interesting.
Do SpaceX's Starship rocket
Up!!
Is it too new? I know SpaceX is literally changing and refining it daily right now.
Perhaps he should wait until at least the Artemis ready configuration is built? Or at the very least its super heavy booster is. But I'm right there with you!!
Bro with your personality alone it'd be impossible to get a boring video out of you... TH-cam is almost the only thing I watch & so are your bomb ass videos, literally. Thanks simon, life will never be boring as long as your still around my friend
The original console is currently in the hands of a local (Titusville) space history museum. The original console used a joy stick, rather than a wheel. When they upgraded the console, introducing the steering wheel, they gave the original to the crawler designer Donald "Buck" Buchannan (Senior Design Engineer for KSC). One of my cousins married Don and I was thrilled to walk through his memorabilia room, with the crawler console. As a space fan, it was a very special treat to put my hands on the console and 'steer' it.
You don't get an idea of the scale of the VAB until you either get close enough to see how small the normal size door appear, or far enough away to really compare it to other (large) buildings
It has been a decade or more since I saw the building, but I still remember how insanely large it is.
I visited a few years ago and remember first seeing the VAB while driving over the A1A bridge to Cocoa Beach, 14 miles away.
The funniest thing is comparing photos of the Saturn V and Shuttle leaving the VAB. You can tell that the VAB was made for the Saturn V with maybe a little room to grow. It almost looks like you could stack two space shuttles ontop of each other and it would still fit in the VAB.
20-ish years ago, I was at Kennedy Space Center as part of a school trip. There was a shuttle launch that morning, that for some reason we didn't go to see as originally planned. We ended up at KSC later in the day. Part of our tour had a bus drive along the crawlerway, which still had the CT parked on it waiting on a return trip to the VAB. Getting an up close view of that beast more than made up for missing the shuttle launch. Even already knowing all about it from an interest in space exploration, the scale was still surprising. It's something you really have to see in person.
Before I took a tour of the Kennedy Space Center a few years ago, I'd never really given the crawlers much thought. But seeing one of these things up close in person, it's impossible not to think about what an astonishing feat of engineering they are. (What do/did the Russians use, by the way?)
The Russians take a different approach. Instead of building the launch vehicle standing upright, they assemble it lying down and move it with a train to the launch site where it is then lifted upright and fueled ready for launch. At least, that's what they do for Soyuz, I believe their Buran shuttle was transported vertically like the US shuttle but of course it was never used as much as the STS.
China uses a bit of a mix between the 2 btw, assembling the rockets in the upright position and moving them to launch position with a large transporter that looks a lot like the NASA ones, but again runs on rails instead of being a tracked vehicle
@@GeneralBrae Soyuz rides a single track. Its a thin enough rocket that a single wide launcher was sufficient. But during the design of the N1, they knew that would just roll off the single wide track (if not completely crush the track under it's weight). So there are a couple (?) of launch pads with two parallel tracks. The N1 launch rail was super wide. More similar to the NASA mobile launch platforms. under 4 corners it had train bogies riding the parallel tracks. It was pulled by two engines, at the front corners. How they managed to synchronize and not bind up the platform is a mystery ;) Not a whole lot of info exists regarding the single Buran launch, but I'm pretty confident they reused the N1 transport, platforms and pad.
Though Soyuz is on a single track, its not typical freight gauge. its still set quite wide.
Soyuz: gklaunch.ru/wp-content/uploads/2019/01/03_vostochny.jpg
N1: pbs.twimg.com/media/Eght3bzVkAEEYhw.jpg
heres a much better view of the N1, both engines and tracks clear: i.pinimg.com/originals/f8/87/e4/f887e4db60f59dbadc535a034eff2e6c.jpg
And here is Buran on the pad. Look between the towers, and follow back, you can just barely make out the parallel tracks. cdn.britannica.com/98/125698-050-8B18FBE5/space-shuttle-Soviet-booster-rocket-launch-Buran-November-1988.jpg
Your in-depth exploration & explanation of the crawlers was necessary to clarify for average viewers how much PAPER planning, SLIDE-RULE engineering & ANALOG operating equipment was needed before a launch and how incredibly integrated it is to balance & carry vertically standing Saturn & Shuttle assemblies for the two miles to launch pads and supporting & surviving the forces of liftoffs.
Thank You, Simon, for producing these well explained videos and especially this one.
Great video as always Simon. One correction - its the Space Launch System (SLS). Thank you for making these videos!!!
I was working at NASA at the time when there were 2 shuttles passing by each other outside the VAB. One was coming back from the pad due to multiple launch failures (I forget which), and the other was leaving to be launched. Standing around 200M away, you could feel the ground tremble as the crawler moved forward.
I was in the VAB in 77 when they opened it to the public for the Bicentennial, and that thing is FREAKING MASSIVE! You can get vertigo just looking up at the roof. You DEFINITELY need to do a video about the VAB now. After that, maybe document the Canaveral side of the cape where the military and civilian launches take off.
Simon, if we found this boring we would not either ask for it, nor watch it.
Oh can you now do the VAB, the Vehicle Assembly Building please?
Happy to see this video finally come. Seeing CT-1 on my tour there, It was eye opening. Such a epic piece of engineering.
It's the "Space Launch SYSTEM", not "Space Launch shuttle".
I love those Crawlers, I live about 40 miles away and viewed them up Close in 1969 right before the Apollo 11 Launch, they are massive to say the least.....and probably the best bargain ever gotten by NASA other than the VAB building or the 39A and 39B pads.....cheers from Florida....
I know you called it Space Launch Shuttle to piss everyone off. Well played sir.
Comments go wild, interaction stats increase, monetisation through the roof. Good, I like this channel.
I worked out at NASA for a short time and did get to see one of these bad boys up close. My God what a real Titan! Hope they get many more years of service out of them.
Equally impressive is how SpaceX have been able to design out so much of NASA's goliath infrastructure for assembly and transport down to bare bones essentials.
Their rocket stage assembly is a tall tin shed, their transporter can be bought off the shelf now (or hired), their launch mount is as basic as it can be made. Yet the Starship will be bigger.
Such is the advantage of progress, hindsight, lean management and a coherent in house design philosophy.
Yeah they have rethought every bit of engineering and infrastructure that goes into building and launching rockets. It's amazing how much they can do with so much less money when they strip away everything that's not needed.
They have indeed innovated enormously in lowering costs.
But, I would note that a fully-loaded Superheavy/Starship simply can't be launched from the current Boca Chica facility. They're working on building a launch pad and fueling facility into a (completely rebuilt) oil platform. It'll be a respectable bit of large-scale engineering in its own right.
@@aceg81 But even that is an approach a NASA contracted builder of a sea launch platform would not do, it would be an over engineered clean sheet of paper build.
Space X go, lets repurpose a drilling platform, gut it to the essentials retain its structural integrity, keep its stabilizing systems, any rooms that can be repurposed, and work within the envelope of its existing dimensions. It could back fire but I'm sure it was an approach that was taken after a study of potential time and money savings.
A NASA contractor is going to make something that is a statement piece on their capability and would be over size I suspect to avoid painting themselves into a corner of space to work with and considerable margins of extra capacity to do what it intended to do.
Tbh... SpaceX is not outdesigning anyone... They use quite old tech
@@Markus-zb5zd Simpler tech newer thinking.
I traveled to Florida a few years back and me and my dad went to the KSC. It was so cool to see everything there including the VAB and one of the Crawlers. Quick fact, the VAB has the largest American flag painted on the side
Mega projects in progress (not competed yet):
Starlink
Race to the moon - Redux
How about Star Ship and Super Heavy too
I would personally love to see a Megaproject about some of the successful countries switch to renewable energy sources
The way Starship is progressing they may have a orbital launch by early august everything going perfect and if they complete a number of successful launches and manage to land one or two i don't see any long term use of SLS it just wont make any financial sense but this is government we are talking about lol.
@@ZAELish SLS makes a backup for Starship in the off chance that Starship fails (not likely IMO) albeit an obscenely expensive one.
Got to see this in 1971.... It is massive!
I got a picture of myself next to one... Can't do that today!
We were supposed to watch a launch but it rained.. So we watched it on TV a week later!
As a kid from East Germany in 1980-83 living in Miami Florida, my father drove us in middle of the night to Cape Kennedy several times to catch the launch of the Shuttle. We never had much to say between us, but I'll never forget him saying, "this is America, be an American man and be loyal".
The crawler, even with its massive fuel consumption, is still 4x more efficient than Grandpa Simpson's car. Instead of 40 rods, it gets 160 rods to the hogshead. :)
I think it's great that you actually read comments. Thanks for all you do mate. Much appreciated!
Another great and informative video, sir. I got up close and personal with the crawler 1970ish on a tour as a CAP Cadet. Video doesn’t convey its, nor the VABs, enormity. Had another brush with NASA and the Apollo program in 1975 during the Apollo-Soyuz Apollo recovery. Deke Slayton, ever gracious, took the time to shake the hands of a couple young Marines standing guard. I even found myself in one of NASA’s official photos for that mission. I will forever be a fan and supporter of the space program for those experiences.
Thank you for this video. You didn’t sound most pleased to be presenting it however I am most pleased that you did!
A few errors here and there, but overall an OK video about the CTs.
I was at Kennedy Space Center last Friday! Was such a cool experience. The entrance where you pay to park is mounted on what look like crawler tracks. I wish i would have been able to see one of these up close.
Ya, this made me happy to see. Lot of people don’t get to see this side of the world. Gives a bit more appreciation if you know what I mean lol
I've been lucky enough to visit KSC three times and it never gets old and I'm sure on one of the tours they said they used a certain type of river bed rock maybe from Alabama for the roadway as it will not produce any sparks as the mega crawler travels to the launch pad.
Mmm... But I think that the rockets are moved without fuel... AFAIK they are filled in the launch pad...
I think it depends, I know some rockets require internal pressure in their fuel tank in order to support their own weight, so while not fully fueled, they are at least fuelled enough to keep them from collapsing
@@battlesheep2552 Mmm... also not sure... rockets like the Atlas, with balloon fuel tanks, were pressurized with gas when not fueled to avoid collapsing. The only ones that, AFAIK, were fueled, for obvious reasons, are the solid fuel rockets...
Thanks for this video Simon. Been a fan of our space program since I was a kid. The CTs have always fascinated me.
Its a bloody engineering projects channel. You might find it boring but this is the kind of shit we love. Id (and do) happily watch a 1hr long deep dive into this (or anything spacey)
This was the most interesting boring educational video ever!
The reason the first carrier's undercarriage fell apart was that it was running on a hard concrete road. The stripping shovels Marion was used to designing always ran on dirt.
When they put that layer of gravel on the road things got much better because it gave a little.
That time lapse of the carrier going down the road makes it look like the driver was drunk, weaving all over the road.
This thing reminds me of a G.I. Joe playset that only kids whose wealthy parents were going through an acrimonious divorce would own.
Dude, no joke, in 1984 my friend had a birthday party, his dad managed a hotel, one of the rooms was for the party and when we were let in it was literally covered with every single G.I. Joe toy/gadget you could think of at that time, EVERYTHING!
It'd be that or the F.L.A.G.
One of my cousins actually worked on the upgrades for #2. I got to see it up close and it was incredible!
Thanks for the video Simon!! I think you should do a Megaproject on yourself on what it takes to put together these videos...!!
I just realized one of the most useful things I've learned from Simon: a better idea of the metric system.
I did not ask for this topic, but thank you never the less for making a video on it.
There is your next series to do Simon. Unsung heros. Do a entire series covering that
Far from boring. Good one Simon. Thanks.
Hi Simon. New to the channel but love your work. As a future Megaproject, project, I highly recommend looking into Hinckley Point C. The BBC have done a four part documentary on it and its insane. But for the international viewers of your channel who can't get the BBC, please consider it.
yeah am an international viewer, plus side would be proliferation through awareness and might even reduce the stigma and fear about Nuclear Power.
This is amazing! I’ve been hoping for this video to come!
I was lucky enough to get to NASA and see one of these crawling back after a shuttle launch. They are big and amazing how much they carry
Really puts into perspective how efficient SpaceX starship is going to be, and in many ways already is. The parts are assembled near the launchpad and moved empty to the launchpad to be loaded with fuel on site. A simple semi trailer can move the parts.
Thank you for doing this video! Always wanted to learn more about them!
space stuff is so cool. thank you for covering this.
The Vehicle Assembly Building is indeed immense. I took a NASA bus tour of the Kennedy Space Center in 1981 and as we appeared to be pulling up to its base the driver told us it was still five miles away.
Not boring. Thanks Simon.
A side fact about the VAB that IMO should have been included is that if wasn't for air-conditioning, the internal open-space volume of the VAB is big enough to have its own weather patterns. I found that out on a trip to the Kennedy Space Center in 2001.
It's always good to use units that everyone can easily grasp and relate to, such as fifths of the Brooklyn Bridge.
Thanks for the refreshment
8:45 "A fully fuelled space shuttle..." Do you really think they'd transport it fully fuelled!?!? No! It is fuelled on the launch pad.
Space Launch System. Crawler sings (or sung) to paraphrase that famous song from a similar time, "The road isn't long, and there aren't many turns, it ain't heavy its a Saturn/Space Shuttle/Space Launch System/what ever comes neeeeeeeeeext".
Thank you as I did enjoy this as I have always loved everything space-related.
My father was employed at KSC for almost 20 years during the 80s and 90s. I had the opportunity to go out there quite a few times, and I can tell you that photos of the crawler do not do it any justice. It has to be seen in person to understand how massive it is. Every time I see it, I always think of the Jawa Sandcrawler. 🤣
Best, most interesting of Simon's video yet
Not boring!!!!! Love these shows about machine tech.
I was one of the people who suggested the Crawler Transporter, so thanks for doing this!
I live near the space center and I’ve been under these things and inside them and they’re amazing, just absolutely massive.
I love seeing the business blaze influences in your other channels now a days!
This video came out at the perfect time. Just got done watching another one about the theoretical limit of the size and weight of land based vehicles. And the Crawlers were mentioned as part of it....and I literally though, "Huh. I'd like to know more about those things." So likes and subs for perfect timing.
I know EXACTLY where the bit with the horse mask came from.
I love Tomska. 7:59
Your wonderful. You make these facts into the Amazing Interesting watchable pieces of entertainment. I suffer from Stress Insomnia. . You get me through the night. Thank You
Seeing one in person is unbelievable
If you're gonna talk about the Crawler Transporter, you should talk about the Bagger 288, another massive machine
do please make a side projects video of some major US particle acceleratores such as; SLAC, Fermi Lab, Argonne's APS, and Sanda's lab accelerator
Space work isn't about the big things but rather that which is step by step and inch by inch! 🚀
It's SLS - Space Lounch System ... and the vehicles are not moved when loaded with fuel. They are fuelled up hours prior lift off.
the solid rockets are by necessity, fueled when manufactured. That being said, I would expect them to be tremendously stable until actually lit.
I went down to the Kennedy Space Center a few years ago. They really were not “shut down” as much as they were retooling for the next series of missions. It was an interesting trip.
Grew up in Titusville and port Saint John and had the pleasure of meeting one of the operators for the crawler
Which is cooler than meeting astronauts when I worked at the visitors center at NASA
Simon this video was actually interesting, that crawler is huge!
Not boring at all Simon. It was great!
I didn't ask for it, but I certainly enjoyed it. Thank you to the commentators and of course the host and bts people!
This is important. Thank you.
It is awesome to see it. Its size is so much bigger in person that seeing it on T.V. And not even a little bit boring!
If you think this video is boring, you probably aren’t a fan of all things space. These crawlers are fascinating and a wonderful example of 🇺🇸 ingenuity and engineering might.
I really enjoyed this video! Thank you.
And released on the same day that the space launch system core stage is rotated vertical in the VAB as well. Great timing 👏
Thank you so much for doing this video.
I recently met than man that owned the company that cast all of the cast iron crawler pads for them. He's a friend of a friend, and a very interesting fellow.
Great video,I wasn't bored at all😊😊👍👍👊
Over a couple of visits to Kennedy Space Center I managed to see an empty crawler in action and was staggered by the sheer size of it, and the fact it could move. Not as impressive as an actual Shuttle launch though - watched the launch of STS-100 in April 2001 and will always remember the punch in the chest when the sound wave hits you. Even my wheelchair-bound mother who had no interest in space flight said it was the most amazing experience she ever had.
