In about 2002, I had the privilege/headache of participating in the correction of an oversight in the construction of the NBL: the adjacent shower room. At the time I was working for an MEP engineering firm near Houston. NASA had discovered that the shower room was collecting too much humidity as trainees shed the waterlogged equipment. The room was musty, mildewed, and collecting mold within a few years of the NBL's construction (I have no idea if it was the same shower room used for the tiny predecessor). It badly needed a renovation before it became a health hazard itself. Just like the pool has an incredible number of water changes, they had spec'd an inordinate number of air changes for the remodel to the shower room in an effort to thoroughly remove humidity and quickly dry the room after each use. It was something crazy like 10 or 12 air changes per hour. We ducted as much air from outside the building as we could, pulled every cubic foot of air from every nearby return plenum, and still couldn't hit their target without causing ceiling tiles to start dancing out of the grid in nearby areas. During a progress meeting with a few NASA suits and engineers, we patiently explained to them that their desired number of air changes was simply impossible because there wasn't enough available air, but the number we had managed was several times more than was needed to quickly dry the room. The shower room shares a wall with the pool room and a **NASA engineer**, I kid you not, suggested that we get more air by pulling some from the giant pool room. My boss and I stared at each other incredulously and uncomfortably, wondering who was going to tell this "world-class NASA engineer" that pulling air from a room with a giant pool would not be a productive contribution to an effort to DRY OUT the air. I don't recall which of us finally said something or how we handled it, but I would like to think that we handled it gracefully enough to keep our customer's customer from feeling foolish.
@HVAC Quality Assurance I wish I could say for sure. The dudes at the meeting introduced themselves and each other with elaborate bureaucratic titles, some ending with "manager" and others ending with "engineer". This bright guy was one who had a title that ended in "engineer". Not that it matters. By the way they were talking, I didn't think any of them had written the spec. It was probably written by some senior-level functionary who couldn't be bothered to come down from his ivory tower for a petty little progress meeting. It was also so long ago that I wouldn't recognize a single person from that meeting if I bumped into them on the street today. I don't even remember who the architect was on the job, and he was at the meeting with us. I doubt that explaining to them that air changes could simply be calculated by dividing expected vapor production by the inverse of incoming air humidity levels would have meant anything to them or to the person who wrote the spec. They just said "Hmmm... twelve air changes sounds like a nice, large number. Let's demand that!" I think my math came down to three and some change being plenty, even when using humid Houston air from outdoors for makeup, and we had managed something crazy like six or eight per hour (thanks largely to the tiny air volume in the shower room). That's nuts. It's not a decontamination chamber! They had an arbitrary target number and wanted it.

I visited the WET-F at Johnson Space Center for the first time back in 1989 when I was working on Space Station. The astronauts were evaluating our prototypes against other designs. I was part of a team working at Lockheed Martin. It was very satisfying when the astronauts said they liked our design the best. That was good times in my engineering career.
I had a family friend that was a higher up manager in the astronaut training program. He got me in to see the zero G pool, the giant vacuum chamber, the ISS control room (which was never used), and a couple other juicy places that are not open to the public. The pool is just huge. Seeing the size listed versus seeing it in person is two different things.
Hey Simon. I wanted to let you know that I wasn't feeling all that positive tonight because it was my favorite holiday and I worked till 1 am when I finally got off, the only family I had fell asleep so I was alone. You helped me a lot to just bring some positivity and help me have a good night. Thank you, Simon, Brad.
I go to University of Maryland for aerospace engineering, we got a neutral buoyancy tank there too. I work at that lab, it's so cool. Divers do regularly go in the tank, though it's mainly meant for testing hardware for microgravity and not training astronauts. It's an amazing opportunity to work there.
So one of the more interesting tidbits about the NBL that I learned from the astronauts themselves: If you're in the SCUBA gear, working as an assistant/safety diver/etc... you get hazard pay. If you're in the "Space Suit" you don't.
As a kid I remember touring NASA Johnson Space Center and the NBL. Being fascinated by all things space and astronomy related it was absolutely amazing. As an adult I have gotten the opportunity to work at Johnson Space Center several times and I still turn into a kid and nerd every time I’m out there. It definitely isn’t what it used to be after retirement of the space shuttle program and SpaceX taking over a lot of the activities. The NBL is now leased out to different companies when not in use by NASA for training. It is used for testing remotely operating vehicles (ROV) and helicopter escape training to prepare oilfield workers what to do if a helicopter crashes into the water when flying out to the rigs. The NBL is a really awesome facility.
I did some architectural work in some buildings at JSC. Every time I went there on the job, they'd convince me in taking the tour again. Got excited every time. Just as much as I did when I was a kid in the 90s.
I never thought of it as more than an extra large pool, and while that is generally what it is, it's so much more, on top of the task of just making it and using it. hell, 20 hours to plan for every hour of the hubble mission, crazy
Yeah I worked in a ready-mix concrete plant and well I'm not sure where Simon got the idea that the trucks are totaled if the concrete hardens... They're not we have chippers because the trucks aren't going to be completely emptied perfectly every load so the dried concrete does build up, and planning a continuous pour isn't a great difficulty we did it weekly for government jobs such as runways, bridges, or roads because you can't have a hard line between where the last pour ended and the new one started. Basically everything about this was normal as in the same things you'd do pouring any large yardage job would cover everything they needed.
Having been there in person, I can say that just walking into the room dispels any notion of “ordinary”. It’s an absolutely incredible, fully adaptive facility.
@@Vincent_A Yep. Using TNT, they were able to get all of the cement out of the mixer...along with the tires, the steering wheel, the engine, the gas tank...basically they got the entire cement mixer out of the cement mixer. 🤣
Same here at first. I just thought it looked cool, so thought I could make a video about it. The thing about building the curved walls so they would get pushed in with the weight of the water blew my mind.
Beautifully done! I actually visited Johnson Space Center in 1994 and got to see the NBL's predecessor! It was VERY interesting, and that particular day they were testing out some new designs for space station modules. Loved this video, great job to Simon and team!!
I'm glad you mentioned how they take care of the water, but I really would like to know more about that. What do they have to take into account, with all the equipment, and people going in and out of there? What pumps/plumbing setup do they have? How does it work? What chemicals do they use to keep it crystal clear, and safe for equipment and divers and the structure itself?
If the walls were concave, i.e. distance between walls at the middle greater then at the top and bottom ( ) , then adding water to the pool would not make the walls vertical when full. I think you mean the walls were poured convex, as in distance between walls at the middle is less than at the top and bottom ) ( .
On a similar subject to this you oughta do a video on the SETT (Submarine Escape Training Tower) a 30 meter deep column pool in Gosport where submariners train to escape stricken submarines. I loved my training there, although I scared the instructors at the top on my first ascent because I was loving it so much I was doing the rollercoaster scream and they thought I was dying.
What makes all of this even more impressive is the fact that NASA didn't even exist before the Sixties. If you go back and see how they first started training the original Mercury 7 astronauts, it was comical because they had no idea how to train them, so training consisted of some really ridiculous things. The film and book "The Right Stuff" is a great example of that. NASA has become an extraordinary agency.
Pretty sure it was actually buzz aldrins idea to use the pool as training for his spacewalk during the Gemini program after the almost disastrous spacewalk of Ed white
You forgot to mention it was "Buzz" Aldrin who discovered that using a neutral buoyancy pool was the best way to train for for spacewalks. His underwater training with a mockup of the Agena booster rocket in 1966 showed that by placing handholds and footholds in strategic locations, you could work during a spacewalk.
NASA actually rents out part of that facility to an offshore survival school for people working on offshore drilling platforms. I went to the school back in 2013. We were performing escape from an upside down underwater crashed helicopter drills at on end of the pool and astronauts were training in the other end at the same time. And yes it was a s cool being there as you think it is.
the one in Huntsville has a interesting story. A smaller version was done unofficially with some side budget by some employees. But they wanted a bigger one and so they needed help. They invited Von Braun (Marshall director) to test it. He was so convinced by it that he helped fund the new one creatively bypassing Nasa's financing rules. And when Skylab had it's trouble, some Nasa higher ups realised that they had a Neutral Buoyancy tank big enough to simulate and train the repair efforts, arguably saving Skylab. Even before it was used to convince said higher ups that the wet workshop idea for Skylab was a really bad one. Apparently Von Braun invited George Mueller to try to fit out an empty tank as space station, in a space suit in space.
I remember walking by this during an open house at the JSC, and being incredibly freaked out at how deep it was! As an adult now I'd be just fine, but I couldn't swim as a kid and all I could think about was falling in and getting stuck in all that machinery!
Mrs Richards: "I paid for a room with a view!" Basil: (pointing to the lovely view) "That is Torquay, Madam ." Mrs Richards: "It's not good enough!" Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?..." Mrs Richards: "Don't be silly! I expect to be able to see the sea !" Basil: "You can see the sea, it's over there between the land and the sky." Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction." Basil: "Why?! Because Krakatoa's not erupting at the moment ?"
Getting lost on a space walk would honestly be the worst way to go, just floating away or down to your death, anyone ever seen love death and robots: a helping hand. FUCK THAT SHIT
Currently at the NBL, our team is spinning up training for 1/6th G with new suits. All of this is not possible without all the taxpayers seeing the value in NASA's goals. So thanks, it is a neat place to work.
One thing I've always been curious about is how they handle the change in water pressure as you go down. Does the suit automatically adjusts its buoyancy as the training astronaut goes deeper/shallower?
They’ve got Scuba chaperones who probably help with trim and adjustments. In normal diving, that much depth and pressure does make a difference, you’re totally right.
It's so funny seeing the astronauts there and in the background there's like an 80% naked man wtf hahaha. Like how do you k ow these photos didn't come from the moon? Well theres the naked dude in the back...
The one thing the NBL will never simulate though is the effect of 0 G on the inner ear! The people in the tank are still feeling 1 G, their motions are only approximating what their motions will be like in space.
this must be were all the bubbles in space videos come from. few green screens some actors and a few billion dollars you got a master piece in deception.
Do they do testing in the dark as well as lighted? I remember the account of Luca Parmitano, the Italian astronaut who nearly drowned in his EVA suit, making his way back to the hatch, and the sun set, putting him and the ISS in total darkness having to feel his way back
I work at the NBL. We do turn off the lights sometimes to let the astronauts work in the dark. Remember that on the ISS they have a sunrise or sunset every approx 45 mins!
I have an idea for a Mega Project. Iam curious on the United States Prototype Electric Car Project and why it failed and was covered up and classified and all records and prototype vehicles destroyed.
Not sure what’s the issue with getting the trucks too early. Theyre cargo hold rotates on purpose. To prevent exactly that - not letting it sit. Unless truck-mixers r not used in the states (god knows why that would be)
They don't include this in any of the tours unfortunately. As cool as it would be to check it out they don't let anybody near it. My information is valid as of Christmas 2019.
Love you Simon you provide me with random facts and entertainment to distract me from the crazy nonsense going on here in the States of America. Thanks!
Unfortunately, Simon, the bit about the test pilots was NOT because of the reasons you listed. Oh, sure, it was the public reason given, but the real reason was to exclude the MANY women pilots that were just as good, if not better, than any of the Mercury group.
I wonder if that's 20 hours of a team's time or 20 person-hours in total to plan a single hour of space walk. A 5 person team spending 4 hours each to plan a single hour sounds reasonable, but if group of people spends 20 hours then that's quite something.
Right near the beginning of the video I could have sworn that you said something about global warming just being a part of the process that will send us to other planets. What?
And we overthink things way too much like gravity on a space base why not just use stretchy cords and tracks that lock to the floor the stretchy cards are attached to a belt that you wear that pulls you down to the floor and it pulls you down hard enough that if you're not actually resisting it you will squat but it won't make you squat hard you know what I'm saying as long as you resist normal you will stand normal you could also have rollers attached to the suits under the arms and stuff like that and attach different types of bungee cords a resistance suit it's not that damn difficult

Could you do a video on the dubai largest swimmimg pool
Biggest question I have that you didn't cover is how do they deal with the buoyancy of the oxygen in the spacesuits?
Here's an idea for a Megaproject....
Do a video or videos of USSR sending probes to Venus.
One thing I've always been curious about is how they handle the change in water pressure as you go down. Does the suit automatically adjusts its buoyancy as the training astronaut goes deeper/shallower?
At the depths of the pool, the water pressure doesn't really matter.
They’ve got Scuba chaperones who probably help with trim and adjustments. In normal diving, that much depth and pressure does make a difference, you’re totally right.
@@billbill8555 You're correct. They do periodic weigh outs throughout the run and the divers add or take away weights. I work at the NBL.

I'd say happy 4th of July but you being British you probably wouldn't understand lol ya know rolling most of the world for centuries n all that 😂
Not sure what’s the issue with getting the trucks too early. Theyre cargo hold rotates on purpose. To prevent exactly that - not letting it sit.
Unless truck-mixers r not used in the states (god knows why that would be)
Hmmmm it’s like they needed somewhere to film that gave the impression of being in space 🤔
Well, if your education and intelligence level thinks this looks like being in side then your education was terrible.
I hate to point this out but the walls were convex not concave . If they where concave they would have bowed outward fron center
I think you meant convex.
They don't include this in any of the tours unfortunately. As cool as it would be to check it out they don't let anybody near it. My information is valid as of Christmas 2019.
Imagine a pool big enough to fit a space ship inside
That aquarium in the Burj Khalifa?
Imagine dropping your keys in there...
I think you mixed concave and convex up🤔
Wonder if NASA is going to build a much more bigger NBL in the future.
“Much more bigger…” also know as simply “larger”.
I bet no one pees in this pool.
I heard somewhere that in case of emergency, this pool can be drained in 30 seconds or something. Is that true?
0:20 Oh I totally believe on this one Simon, I really do believe you.
0:31 Omg Simon, are you a space lizard YT channel lord??
Love you Simon you provide me with random facts and entertainment to distract me from the crazy nonsense going on here in the States of America. Thanks!
Well, if you lok fter it, a "modern" pool will last for a century or more, so 25 years is just spring chicken territory... :P
Unfortunately, Simon, the bit about the test pilots was NOT because of the reasons you listed. Oh, sure, it was the public reason given, but the real reason was to exclude the MANY women pilots that were just as good, if not better, than any of the Mercury group.
The water must be warm in there, because the divers do not wear wet suits. So why don't they wear Speedos?
It has only operated for 25 years? 1997? I thought it launched in 1990.
I wonder if that's 20 hours of a team's time or 20 person-hours in total to plan a single hour of space walk. A 5 person team spending 4 hours each to plan a single hour sounds reasonable, but if group of people spends 20 hours then that's quite something.
Right near the beginning of the video I could have sworn that you said something about global warming just being a part of the process that will send us to other planets. What?
And we overthink things way too much like gravity on a space base why not just use stretchy cords and tracks that lock to the floor the stretchy cards are attached to a belt that you wear that pulls you down to the floor and it pulls you down hard enough that if you're not actually resisting it you will squat but it won't make you squat hard you know what I'm saying as long as you resist normal you will stand normal you could also have rollers attached to the suits under the arms and stuff like that and attach different types of bungee cords a resistance suit it's not that damn difficult
Simon, you said “…practice makes perfect…”
This is incorrect.
It should have been written as “…perfect practice makes perfect…”
Built in a pool because nasa can't go to space . Special effects nasa
Covex walks?
I was there a week ago
Totally not where they film ISS footage with bubbles.
Thank - you . ( 2022 / Aug / 01 )
Why would someone suffer decompression sickness at a max 40ft deep
time
The bigger risk is arterial gas embolism.

Ape-X predators. I see what you did there, even if it wasn't intentional.
I wanted to be a diver here so bad.
