When I was in the US Navy's Submarine Service, we had CO2 scrubbers that were designed to remove the carbon from the air. One one patrol we ran through a rough spot when guys were falling asleep on watch, were grouchy as heck and just weren't with it mentally - memory issues and cognitive impairment and basically everyone had headaches. Eventually it was realized that some of the sensors had failed. After the repair it was found that our oxygen level had dropped to about 15% and our CO2 level was significantly higher than it was supposed to be.
Seems that oxygen stuff, and that carbon stuff is important.
Lpppppppppllplp
So without carbon scrubbing I would have about 3 days worth of air if I got trapped in the mine.
So long as there's no additional gasses.
Then blast away
Hey! Guess who watches SFIA. Our spirits have been lifted knowing this.

let me fix that
The international space station is actually in a decaying orbit due slight atmospheric drag. This means it needs to do periodic orbital reboosts to maintain it's orbit. The advantage of this is that anything ejected from the IIS will slow down due to atmospheric drag until it enters the main atmosphere and burns up. Therefore there is no long term space junk problem caused by waste from the IIS.
lol that was the least effective censor beep I've heard in a long time.
The channel has a well known beep impediment.
It was the thong of bleeps.
Oh wow, you were not kidding. That was silly.
What a great day!
- New isaac Arthur video (gotta love Thursdays)
- New kurzgesagt video
- SpaceX launch

Woow. You're a real charmer aren't you. Random off topic attacks are kinda sad you know.
Kuralthys Damn weebs
correction: Such organisms are called "diazotrophs". From here, various microorganisms convert ammonia to other nitrogen compounds that are easier for plants to use. In this way,plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plantroots
plants do not breathe nitrogen.
I just recently found Isaac Arthur and frankly his channel is eating my life. Every time I sit down to watch one video he mentions like a dozen concepts all of which I cant help but go look up and watch. I dont think I've ever spent less than two hours watching this stuff lol
i always wind down after a hard day smoke a bowl and listen to this channel until i pass out. thanks for this amazing content.
Your videos are so awesome. I cannot imagine how hard you have to work to produce them, but THANK YOU for your time and effort you put into them. In 10 years I never subscribed to any channel...except yours.
It's a lot of work but also a lot of fun, so I enjoy it.
OK, I got in to 2:19 and the Galaxy Quest quote killed me! I just had to stop and comment: I love it. Now, back to the show.
If there is a hole in u ship in obit they say put yours middle leg in it
I'm proud of being with you almost since the beginning! The production value of the videos is getting better and better!
:) I'm always glad to hear from the early birds.
"Yes there is a lot of s**t in orbit" ha ha, Christ I could never have seen that coming, Isaac swears so infrequently I almost died laughing.
Hi and greetings from Germany. First I have to say that I think your voice is not only very nice but you are very easy to follow and undertsand (without captions, at least I have no problem).
I often listen to discussions like Isaac Asimov Memorial Debate or lectures by Dr. Tyson, Dr Kraus, Dr. Dawkins and more, because their topics usually simply fascinate me.
After one of this I stumbled over your channel and man I got hooked very fast. I think I got through 1/2 your videos in 2-3 evenings. And in my opinion you are incredible, the way you explain and break down complex topics like quantum computing is awesome.
Please keep up the good work and best wishes to you.
greetings flo
My dear fellow, I just want to say THANK YOU SO VERY MUCH!!! Even though it was only a tidbit, you are one of THE FEW who have spoken on 3D Printing's ability to aid us in this venture! I dare say, for any who doesnt know how they work, or what they can do as a result, you should definitely look into it. 3D Printing is the wave of the future!!! It thrilled me to hear you someone mention something about it in correlation with space exploration. It is indeed the most useful technology we have to our advantage, and I believe it will help solve many problems or boundaries we have, and may encounter, with the advancement of other technologies. Love all these videos, and wanted to express my greatest of gratitude to you and all responsible for these phenomenal videos! By the way, your speech impairment adds some character to the narrative, and I'm glad you did it yourself, and didn't choose some over voice program to narrate for you. It's truly not at all difficult to understand you, and I enjoy hearing a real voice as opposed to a programmed voice! Please, keep making videos my good man!
The window issue on rotating habitats could be fixed by replacing the windows with a monitor connected to a camera that is not rotating.
That's exactly my thought on the matter. Or at least have the camera rotating once every 24 hours to give the appropriate apparent movement of stars - would be eerie looking out the "window" two or three hours apart and noting that the stars haven't "moved" a millimetre.
In a rotating hab, you'd probably want some sort of cylinder above you, concentric to the spin axis, on which a 360-degree star-scape is projected so that you look up and see the stars overhead - for "night time", during the "day", the screen would glow to provide light...
My faith in humanity grows when i see you're sub number grow haha amazing work brother im loving these discussions.
Thursdays on TH-cam are always so LIT! Isaac absolutely KILLED another one! For the last 30 minutes I stared into the screen and absorbed the information like some kind of space sponge. I don't think I blinked even once.
Isaac PLEASE release some merchandise! I want an Isaac bobble head to put on my dashboard. People be like "Who the hell is that?" I answer your future Supreme Leader. I'd love to buy some shirts too.
SHUT UP NOOB
beautiful! The tie in with mass drivers and "A Trip to the Moon" elevate this episode to a work of art connecting visions of the future from today and our past! Glad to have the book recommendation too - I'll check it out.
my friend Isaac,
I agree with everybody else here, your channel is the best!... I'm going through a lot now, (no job, wife nagging all the time.... etc) but watching your videos keeps me going, I find your voice so soothing and relaxing and your explanations are so crystal clear that I feel as a scientist myself .
Thursday is the best day of my week now.
thank you!
Really enjoying your channel. In the 90s I wrote sourcebooks on spaceships for the Jovian Chronicles RPG. An oreo cookie game with some crunchie science on the outside and softer, less math for fun, on the inside. At that time getting access to information was far more a challenge than the overloading youtube style web. Now the issue is filtering the information to what is useful. This is what I like about your channel. It has information in an accessible and digestable way.
I think a friend of mine in college had a copy of it, or maybe it was just at a game store, though I can't recall anything but the cover art. But yeah I do try to focus on digestible meals when it comes to the topics.
Wow Isaac your level of knowledge on this is so impressive. Particularly liked your calculations on how long atmosphere should last - oxygen vs CO2..
The looney toons reference was cute. I love your channel, Issac! Thanks for making such relaxing and intellectually rich content. You do it like no other.
This is literally one of the most intelligent, informative, worth-to-watch-and-learn channels here on youtube.
Yes !
A glorious New video right after my exams're finished; Could watch every video in this channel all the day !
A belated good luck on those exams :)
Isaac Arthur
Thank you so much Isaac Arthur Senpai :D
i subscribed just yesterday. you do an amazing job "as a hobby". it's also quite a treat to see a reply to almost every comment! wish more creators were as good and as interesting.
p.s. Isaac Arthur, as in Asimov Clarke?
:) It's my actual name, "Isaac Albert Arthur", geeky family.
Finally! I found you! I've been looking for this channel for the past few months, now I'll sub so I don't loose this channel again.
Loving your videos, eating them all up. Ty good sir, Congrats on hitting 350,000 subscribers!!! Much respect from Your friend in Colorado.💖
I love the reference to the quote "Never give up, never surrender". Even after a world wide disaster.
First found your show a couple months ago. Just want to say way cool, my favorite thing on TH-cam. Keep it up!
dude you are eloquent and understandable. anybody that gives you shit talk about a so-called "speech impediment" needs to have their tongue and/or mandible damaged.
I don't know why but hearing on 16:59 that there's "a lot of sh*t in orbit" from you makes me giggle (ipromiseimtotallymature). But in all seriousness, I enjoy your videos as always ^^; -- one of the many many reasons why I am a patron hehe.
:) Cheap speaker/writer trick.
2:53 Many of those can be quite toxic or distracting...
That applies to the living too!
"So you are at a base on the Moon, when you get the phone call from back home on Earth, saying there's been a disaster, and no new supplies will be arriving anymore. What do you do?"
I'm gonna have to science the shit out of this.
_Yeah bitch! Yeah science!_ ;)
Ugh, you're not funny.

I absolutely love yoru content Issac. You bring in so many intellectual topics that most people even don't talk about. By far you are the most creative and greatest content creature in my subscriptions.
Question: How tough would it be to put a rover into Shackleton Crater? We're getting pretty good at putting rovers all the way on MARS so it figures that the Moon would be cake. Yet we seem to know more about Mars than about some of the areas of the Moon that seem to be favored for future habitation. Yet I understand that putting a rover in a precise location isn't perfectly accurate so if something went wrong trying to land inside a crater, we might wind up with a multi-million-dollar pile of debris.
It just seems to me that the Moon is an obvious stepping stone to Mars but we seem to be trying to skip a step.
As always, thanks for the wonderful channel.
When are you writing your own series of Sci Fi books or better yet your own TV show?? Love you man, keep doing what you're doing!!
Another winner here! You manage to squeeze copious amounts of information into almost every sentence! Thank you again
I can't wait for next episode! I really like the mass drive, gauss accelerator concept
Really love it when you compare reality to sci-fi. Really interesting stuff.
love your explanations keep up the good work!!! should have a TV series.
"it's very easy to get dead in life and death situations" damn I guess that's true
I didn't think you had a speech impediment, I just thought you were from Texas
:) The South and New england are pretty regular guesses.
@@isaacarthurSFIA My wife likes the way you sound even tho she does not listen to your videos.
favorite time of the week!!!!!!
mine too
And the least favorite 30 minutes after.
I absolutely love the content you create! The way you apply logic, calculations and cold hard facts blows me away week after week, and makes me dream of a bright future for humanity. Keep up the great work!
Thanks!
I tear the tags off my mattress, I don't backup my hard drive, and I don't turn on Closed Captioning when I listen to Issac Arthur!
Even after everything this channel talked about has already come to fruition, i'll still stick it on to fall asleep to.
Life support, a fitting topic for me at the moment given the amount of celebrating done last for my wife and I's 5th anniversary. Ohhhh boy, here we go!
I'm reminded of when I explained the oxygen metabolism to my first child when he was about two years old. Later, I saw him holding his teddy bear on his knee, explaining to Teddy, "Air has ox'hin and...other stuff we don' need...."
I was very pleased by that second clause, since I hadn't mentioned nitrogen to him-he had intuited it when I told him air CONTAINS oxygen.
Happy Arthur's day everybody.
learning new things, thank you for expanding my brain. Also thank you for no robot voice, you can understand every word said. good work mate
"...most of the H2 is in the Sun and a bit difficult to get at." 😄😅😂🤣
I'm sorry, I know I'm not supposed to dog on the speech impediment, but I couldn't stop chuckling about "oxygen by valium"
ur comment from 2 years ago from 16 20 2020 is right above this one
also one of the top comments
i liked this one so it matches likes with ur old one
Idk why you're undersubscribe man. What an informative video once again! I'm learning a lot!
Hey Issac, great video. I'd recommend seeing the movie "Life" as it could tie into your upcoming "Dead Aliens" episode.
Endlessly fascinating! I love it! The first time I ran into something like this channel was in 1994 as a book by Savage, Marshall T. called "The Millennial Project" Little Brown & Co (P) c1992, 1994. Has anybody else here read it? It's subtitle is 'Colonizing the Galaxy in Eight Easy Steps"
i worked at a robotics manufacturer for semiconductor makers. we had our robots, silicon wafer or flat panel plate handlers in a vacuum chamber, all part of our product. one i remember was a 2 meter across by half a meter high behemouth. it had a 'clam shell' hydraulic 'cap' and many 6cm ports. if it were at vacuum and one opened a port it still took hours before the pressure inside was close enough to atmospheric pressure that there was no force on that 2 meter lid. even a slight pressure difference was a massive force.
Hey Isaac.
Looking at your oxygen chart I can't help but remember a colonisation experiment in which the participants grew more aggressive (iirc) due to a slight decrease in the amount of oxygen they were given. Could a similar scenario take place on earth as a whole, and if so, how so, and how could it be prevented? On that same note, with global warming being such a concern in our day and age, are there more similarly known threats we have to be weary of in the near future (10-1000's years) and could we perhaps have a video about it, assuming there is enough material?
Thanks for the good work! I'm no academic. But this is by far my favourite channel on youtube.
The shit from the ISS is not dumped overboard and left in orbit. It is loaded into canisters and then they are all packed inside a cargo vehicle. These vehicles burn up upon re-entry, completely disposing them. However, the MIR space station did use to dump their shit in orbit.
What a surprise re: MIR!
Which size range would be viable for an alien race? They would need a certain level of technology to travel from another star but how big or small could their physical size be to be able to create and use that technology?
Might be a stupid question but worth a thought.
Well, I've finally finished all of your videos :( This has definitely become my favorite channel on TH-cam.
Now what do I watch!?
Thanks Lycerion, I might suggest Cody's Lab, fun channel, or visiting SF Debris's website.
Maybe PBS Spacetime if you dont know it already? Similar topics, i like Isaac's narration better, while PBS are little more science-heavy. :)
I rarely comment on a video. When I do, I need it to mean something. I’m from Denmark, and I work in IT-Marketing, but I have a hidden scientist in me. I love your videos, your stories and method of explaining. Every Thursday evening I watch the latest episode with great interest, and I try to share and make other people to subscribe. I would love to see you getting 100.000$ pr. Episode from Discovery or any other major channel. Which could bring optimized graphics, and explaining drawings. Good luck from Denmark.
Any video with Vladimir Putin in Space Marine Armour on the thumbnail promises to be a great one. Incidentally, it also helps that we've got one of the brightest content creators on TH-cam producing it.
lol, I didn't make that mental connection, of course I didn't see it till this morning, now its stuck in my head. :)
Wait, what? I thought the Trumpster is supposed to be the incarnation of the God emps of mankind. You guys confuse me. :D
That guy looks way more like Scott Manley than Vladimir Putin to me...
-Runs to grab some food-
Hell yeah.
Awesome channel, very interesting subjects and a great listen on long bus rides.
where do you get your 3d animations?
Love your work, thank you! One question has been bugging me for a while. Given one of our biggest challenges is getting materials into space, why are we not making any effort to recycle space junk? Why do we waste materials by burning them up in the atmosphere, as opposed to parking them in a longer term orbit. Even if we can't recycle it now, why not gather it in a more concentrated space junkyard, so that it's easily accessible when we are ready?
Seems like such a waste of metals, electronics, solar panels, left over traces of fuel...etc. already in orbit.
Basically because retrieving it would tend to take a lot of fuel and require some facility to do the recycling. Much of it is quite tiny too, but we will discuss the options in a month or so.
That feeling when you just finished watching every video this superawesome channel has to offer up until to date and are just taking a brief pause before second run. :) More power to Isaac Arthur!
I am going to promote the living crap out of this channel! My non-geek friends are gonna hate me for sure, probably most of my science nerd friends will hate me too, but who cares. :D
I do even disable my adblock for this!
I wish I had the money to support you on Patreon right now.
It might be some months before I get a regular income. But I definitely intend to support you when I can.
Thank you for introducing me to a passion I might never have known I possess.
YOU are awesome!
I waited this for a long time.
Your channel is incredible. You're truly doing God's work.
Time for another cranial stimulating lesson at the University of Isaac Arthur.... 😃😃
Brain... Activate Sponge Mode! Input Channels Open!!
Hi, Thanks for the amazing videos, I have been watching for a month or so and really enjoy listening to you talk about things that blow my small mind. One question I have is "do you just know all this stuff or do you research for each video or is there a team of you?"
yes, sometimes, and no
Wasn't expecting this episode to get into spin gravity! Very fun episode
Isaac, I look forward to Thursday every week, waiting for the next episode, always much more satisfying than anything on TV. GOT has nothing on you. Also your Like to Dislike ratio must be the best on TH-cam + 99.5% on this video, you must be the most 'Liked' person in the universe. Thanks for doing what your doing.
Metal can be smelted in a pretty simple electric smelter if you have the power. Or maybe even a solar kiln if you don't. It can then be beaten into shapes and then cut and welded to form crude tools.
I was planning on using this for the plot of a space survival game, but I'm not sure if I want to do it small scale or large scale. By which I mean "martian colonist starting with survival equipment" or "colony ship slowly working towards terraforming a planet."
I think that's the best use of 'superfluous' I've ever heard....
What a pleasure to find a science documentary which uses all proper units of weight and measure.Most are shy to use Newtons or Joules.
Isaac, thanks again for the well researched video. Kudos on the quality.
Quick shout out to the Space X guys on another first yesterday for space research. Isaac, could you comment on the price dorps this will produce in space access?
Just a real life example of environmental hostilities at higher altitudes: Nat Geo's Mayday Air Disaster Investigation series, season 17 episode 1 (?) describes the story of a LearJet (very reliable aircraft) leaving Florida to Texas at high altitude and speed (normal for this type of jet). Once the plane crossed the State of Texas, it kept going in the direction of Minnesota. Puzzled and without radio contact, the authorities scrambled fighters to intercept it. The fighters reported not seeing any response from the plane and upon close examination saw the pilot and co-pilot slumped over hanging by the seatbelts. Soon after that, before they could decide if they would shoot it down, the airplane ran out of fuel and went into a tailspin.
The inversigation concluded that a pressurization valve in the back of the airplaned had failed which caused a loos of oxigen. I do not remember why this failures was not immediately indicated on the cokpit, but the timeline suggested that once the warning was soiunded, the pikots were already under the effects of hypoxia and did not simoly put their mask on. All lost, Sad.
An ISRU series made by you would be amazing! I've been thinking a lot about refining the water ice and organic polymer "sand" on Titan to make plastics or using the Lunar regolith to create aluminium alloys such as magnalium. Also, how difficult do you think it would be to insulate an above ground habitat on an incredibly cold world with a significant atmosphere such as Titan, Triton, or Pluto?
Your biggest issue in places like that is that frequently the 'ground' is stuff that turns into a liquid or even a gas at anything approaching room temp, so you need a lot of insulation, and size to the structure too so that you can have a colder second layer you can insulate again perhaps.
Isaac Arthur I never thought of that before!
Or you could make your habitat like a float/boat.
You're productions are amazing, I would love to work on a few models with you.
I'm always glad for any help on that:
isaac.arthur.utube@gmail.com
What you said starting at 2:18 forward about the pills up to it being superfluous, just too funny and true. Love your sense about things. What a ridiculous concept.
"Hmm just in case you MIGHT die, lets give you something so if you take it you WILL die"
Isaac I absolutely love 💘 your channel I wouldn't know what to do with myself if SFIA didn't exist
Hi Arthur. You should put your comments together and publish some books. I bet will be very well received. Give it a try with a Kickstarter project.
Thanks for the great content Isaac!
You're very welcome!
Love your shoes Issac. Thank you
Even after 6 years, this is still one of my favorites.
Awesome!
Contrary to what is stated in this video, plants do not need nitrogen in the air, they get all their nitrogen from the soil. Even those plants that have a symbiotic relationship with nitrogen fixing bacteria can get all their nitrogen from the soil.
Hello from Australia Isaac, love your videos and you are easy to understand my friend.
One of your last points, construction materials could be launched ballisticaly at there destination preferably with a rail gun.
Countries like the US could cut power to homes and Businesses for 5 minutes and transfer energy into the system for each launch window.
We need to fire the imagination of the masses and make the corporate world realize its better to expand then grow.
At first I was caught off guard because I was thinking land line when you said phone call XD and I was thinking, "How would you get a phone call from Earth on the moon?", but then I remembered that I'm using a smart phone right now, and I was like "Duh" XD
2:00 Want proof of this? Ask Jim Lovell. If there was ever a situation that would be considered hopeless, it was Apollo 13. That is probably the best example in history of, you keep trying to survive until you don't have to or you are dead.
Hey Isaac- Or Anyone really..... Could you recommend an online community that goes into topics similar to this? A forum for human space flight using known technology???
never give up, never surrender
I love the Chris Hadfield videos, and your videos, happy Arthursday everyone
Also are you going to do a video for 100k subs?
Upward Bound is exiting me each episode more, I'm really waiting for the mass drivers episode.
Lighting can also be accomplished through fiber optics transfer
can you do an episode on types of space suits(in general)/ types of future space suites. Sava Newman's space suite design looks so cool and was said to get 1/3 of an atmosphere with mechanically applied pressure, I think, but I haven't seen much further info on it.
Dava Newman*
Third person to request that this afternoon, it's kinda tempting too.
Isaac Arthur lol ikr, I'm not sure if her design is meant to be used on space walks or is meant to be more like the orenge launch suites that NASA uses though, so maybe those dope space suits from interstellar are a lil farther away. for Eva's.
Oh you'd never do orange for an EVA, except maybe a very reflective and light orange. Suits tend to be like sewatboxes as is.
Isaac Arthur sweat boxes*, anyways you have a point
22:30 Could you use fiber optics (or camera, or some other technology to change where the light comes in? You could have one end on the floor and the other in the wall. We could even do it with mirrors, making a parascope.
I had the same (but rather vague) idea as your friend for a story. If I ever wanted to write it, that is.
A moon colony (or maybe mars, or maybe both) that is not just ready to be complete self sufficient but has to rely on itself because some disaster happened back home.
Oh well, so hard to have ideas nobody has had before :)
