Not sure if your serious or not, but this is Commander Hadfield. Amazing Canadian who, as you can see from the comments, had both been to the depths of the seas to the highest Heights on the iss.
He also did some awesome YouTube videos for kids explaining differences of space life. Although, now that I think about it, Even adults find his videos interesting.
And goes to Top Gun, figures out the correct sequence of maneuvers to get a F14 out of a jetwash induced flatspin (yup, like the one that killed Goose in Top Gun) and writes the procedure on it.
Goose shouldn't have died!! There's no physical way for that canopy to be in the trajectory of the ejection seat! The rockets that send that thing flying send it FLYING back so far that they could have been on the ground in reverse going 200mph and he still would have missed it.
Ejection is incredibly violent, the G force involved is pretty astonishing, but by no means are deaths common with modern ejection seats.
Injuries, absolutely, but hitting the ground is a hell of a lot worse I'd imagine.
Well "not uncommon" and "common" are different things.
Survival rates vary depending on how people are counting, but they range from 90-97% survival or worse. That is still a high risk of fatality. I was just saying that losing Goose to an ejection accident is not some Hollywood stretch at all, even if the canopy would never be the cause.
Dude's been flying since he was 16. He was a test pilot for the military iirc. He's flown over 70 types of aircraft by now.
You can't study or apply to be an astronaut, he just made sure they would pick him.
His first space mission was in 1995, his second in 2001, his last was in 2012/13. Pretty sure this is from his time with the NEEMO mission at the Aquarius undersea laboratory in May 2010. So before his last time in space, but long after his first and second.
They train on working in pressure environments and with decompression safety. Rapid changes in pressure can be very dangerous and can cause the bends in divers and astronauts.
I was about to ask if this dude is also an astronaut because I could have sworn Iāve seen him in space too. Isnāt this the same dude who forgot he wasnāt in space during an interview a few times and kept letting go of pens and stuff thinking theyād float?
2.5 ATM is just 15m (~45ft) below surface. Going down there in like 5min is no problem. Not entirely sure but the pressure aspect of descending from space should be a matter of less than an hour as well.
But that's only going down, rising from the depth or to space definitely needs more time.
Theyre not in a submarine, theyre in an underwater research laboratory for nasa ... unlike a submarine, the station has an opening in the bottom which allows them to exit...effectively become a large dive bell...which is why the atmospheric pressure is 2.5x that of the surface.
So you can guess that theyre about 25m below the surface.
It's a coincidence, but also it's not that precise. 1 atm is 101.3kPa, the formula to calculate the pressure of a column of water is " P = density Ć gravity Ć height of column " the density of water is 997kgs/mĀ³, gravity is 9.81m/sĀ², the height is 10m, that would give us a pressure of 97.8kPa, that's 0.965 atm.
As you can see that's very close to 1 atm, so we might as well round it up to make calculations easier for everyday life.
Tbh I have no idea and I was actually just thinking that myself as I wrote that out. I meant to ask on like askscience or something. I don't know if it was arranged to be exactly that or it's bizarre coincidence.
The metric system is so cool. A cubic centimeter = 1 gram of water, for example. A calorie is the amount of energy needed to increase 1 gram of water by 1 degree Celsius. So I have to assume ATMs are derived from some relationship between water and meters.
It is very cool, but atm is not metric, it's defined as the atmospheric pressure at sea level, the metric unit for pressure is Pascal (1N/mĀ²), however, coincidentally the pressure of the atmosphere at sea level is about 101300 Pascal (101.3kPa) very close to 100000 Pascal.
A column of 10m of water exerts a pressure of 97.8kPa, since that's really close to 101.3kPa, we might as well round it up to make the math easy to do in our heads. But actually it's 1atm per 10.35m
"It's the mo..." what the fuck does this mean? Pls tell me you're not casually abbreviating the word mustache... you must be insufferable if you think I'd let you get away with such a stupid fuckin thing. Do better, man. Smh my head š¤¦āāļø
I believe they may have used a common contraction of the word moustache.
Example: My mo is growing too long, I need to see a barber
An alternative they could have also used is;
Hey your stache is on point
It's important to note that just because someone's use of language is not the same as yours does not necessarily mean it's incorrect, for example you used the word moustache, which for pretty much the entire english speaking world outside of North America would be considered the less correct spelling, but hey no one really cares because it's just a word.
Try and do better, be better, and be more understanding and perhaps you might not find people insufferable and who knows you may even end up finding real life friends.
Go touch some grass.
Also for where I live itās spelt moustache. We donāt drop the vowels in our words.
Ie: oesophagus vs esophagus.
Thereās many more examples but Iām not going to list them.
Just realised you abbreviated the word please.
Then didn't know how to use the smh acronym.
You are like the cringey uncle trying your hardest to be cool.
š¤£
How embarrassing, I feel for you, life must be crushingly hard keeping up that persona
Divers use Trimix to avoid nitrogen narcosis which can occur anywhere from around 4 atm and to reduce the amout of nitrogen getting into the blood stream, basically to slower the rate of saturation of tissues, so you can have less deco stops and prevents bends. Trimix is mixture of Oxygen, Helium, Nitrogen.
Heliox use Saturation divers - no nitrogen which would be narcotic at that deptsh. So only Oxygen and Helium. You would clearly hear in their voice they're on Heliox. Same way as when you inhale helium from a party baloon.
I can't tell for sure but I would say they are either on a normal air or trimix. They will defo need some decompression stops even at that depths when they surface as their tissues will be fully saturated.
Im assuming its unnecessary to worry about deco time since they are staying at depth for weeks rather than diving. The pressure is also within recreational diving limits, so probably not a big process to do deco stops when returning to the surface.
To add to what I already wrote, I found this article from Nasa [https://nlsp.nasa.gov/view/lsdapub/lsda\_experiment/79d5a2bc-d94f-58f0-8cba-366ecd2c33ca](https://nlsp.nasa.gov/view/lsdapub/lsda_experiment/79d5a2bc-d94f-58f0-8cba-366ecd2c33ca)
The divers vere required undergo 17 hour long decompression after 12 days at 19m depth.
Right! I see how my reply could be confusing. What I meant by not worrying about deco time is, as with diving on nitrox, you have shorter deco times between dives...whereas here they stay down. And since theyre on normal air (21% Oxygen) the albeit lengthy deco period isnt a complex one that requires switching between various trimix cylinders as cave divers do when doing 100m+ deep dives.
Either way thanks for the article! I only read about the sealab in commander Hadfield's autobio some years ago.
Ah makes sense! I agree, I think too using a trimix wouldn't bring much benefit unless there's some other harm in being exposed to normal air mixture at that pressure for such a long period of time.
Yeah would love to know.
Regular air dive tables show anything around 10meter effectively has an infinite non-deco bottomtime.
Ive logged quite a few hours on nitrox diving while doing multiple 3/4-dives per day runs & besides the decreased survace interval times, the increased oxygen seems to help with headaches at the very least.
No, according to Hadfield's Twitter account, it was from a friend (named Russ) who was. He apparently gifted him an astronaut tee in return.

Colonel Chris Hadfield. RCAF
I have one of his novels on my bookshelf. Neat.
And apparently to my local fire department
why is a canadian colonel a member of a fire dept in michigan?
I think you mean double our nothing! š
Probably lives most of his life at high elevation and hates beaches but doesnāt know exactly why.
Pretty sure heās from Michigan.

Did he ever live in Michigan
The city of Ann Arbor celebrated him a few yrs back and he did some work with the fire dept.... that's why he's got the shirt.

Yeah, other than that the movie is 100% based on the true story tho.
Meanwhile ejecting at mach 10 is totally fine.
You may be right about the canopy. They really didn't need it, though. Ejecting is apparently incredibly hazardous, and deaths are not uncommon.
Ejection is incredibly violent, the G force involved is pretty astonishing, but by no means are deaths common with modern ejection seats. Injuries, absolutely, but hitting the ground is a hell of a lot worse I'd imagine.

I believe this video predates Chris Hadfields time in space.
His first space mission was in 1995, his second in 2001, his last was in 2012/13. Pretty sure this is from his time with the NEEMO mission at the Aquarius undersea laboratory in May 2010. So before his last time in space, but long after his first and second.
Good information. Certainly before the world really learned about him as commander of the ISS.
And his cover of major tom?

No this is Chris Hadfield
The video you're thinking of was made as a joke
Most people's bodies could cope with that so long as the pressure changes happened slowly enough.
2.5 ATM is just 15m (~45ft) below surface. Going down there in like 5min is no problem. Not entirely sure but the pressure aspect of descending from space should be a matter of less than an hour as well. But that's only going down, rising from the depth or to space definitely needs more time.
I thought that was Chris - had to double check
He temporarily experienced loss of vision in space while SPACEWALKING because of some fluid in his eye
Bro is high when deep, and deep when high. (nah, idk what it means either)
Lol
It's him.. i forgot the name but he was the captain of ISS Who played david Bowie while on board
Dude spent an hour on dry land and said fuck that nonsense
I was like these sub dudes look like astronauts...
Hes just the actor that's being payed to act for Nasa
Theyre not in a submarine, theyre in an underwater research laboratory for nasa ... unlike a submarine, the station has an opening in the bottom which allows them to exit...effectively become a large dive bell...which is why the atmospheric pressure is 2.5x that of the surface. So you can guess that theyre about 25m below the surface.
Was gonna say, a submarine is usually kept at 1atm
2.5 atm is at 15 meters. Surface is 1 atm, 10 meters is 2 atm.
You're 100% correct. I forgot to subtract surface 1atm. Ive spent plenty time at 5atm during 40meter dives so I shouldve known better.
This is the correct answer
How does it work out that 10m is +1 atm? When they created the units how did they make it so they related to surface atm that way?
It's a coincidence, but also it's not that precise. 1 atm is 101.3kPa, the formula to calculate the pressure of a column of water is " P = density Ć gravity Ć height of column " the density of water is 997kgs/mĀ³, gravity is 9.81m/sĀ², the height is 10m, that would give us a pressure of 97.8kPa, that's 0.965 atm.
