Here's the link again to Part 1: th-cam.com/video/Pv7aigOzQKo/w-d-xo.html Let me add as a note, this was a particularly fun collaboration to do, Paul and I started work a few months back after being introduced by our mutual sponsor, Brilliant, and almost immediately hit on the notion of covering Mars. I always felt like Colonizing Mars episode started a bit too late, well into the colony phase, and wanted to look at it more, and Paul and I were both impressed by the early designs from the 70s for such missions and felt they deserved a good review, so it worked out perfectly and Paul was genuine pleasure to work with. I hope you enjoy Part 1!
Hey Isaac! I just want to let you know that after 3 years I still love your channel as much or even more than in the beginning. Also just for feedback on the cooperation: I watched the episode and had a look at Paul's channel's content and it is awesome too.
The technology needed for a Mars Colony has existed for a few decades: The best efficient transportation between Earth & Mars would be a Space Station in an orbit that crosses the orbits of Earth & Mars. This allows the Station to be heavy enough to have an Aquatic Based Biological Life Support System / Water Jacket Radiation Shield. Biological Waste would be recycled as well as removing Carbon from the Air. Granted that a Second Space Station would need to orbit Mars. A small spacecraft would be need to transfer the crew from one Space Station to the next, and Chemical Rockets would be adequate. A reusable Mars Lander would also be needed. The safest / easiest to transport Mars or Moon Long Term Habitation is created by detonating a Thermonuclear Charge below ground, having first been placed there with a drilling rig. While the residual Radioactive Isotopes would need to be removed by robots, the large glass lined Spherical Chamber would be big enough for a small village, and have excellent shielding from radiation & meteor strikes.
Damn, this why television is dying. I used to watch science oriented content a lot in some channels, but it seems that even what I liked has degraded Here at SFIA we can have awe inspiring content and detailed analysis of many interesting concepts, all that in the format of youtube videos with some major production skill behind. No need to tune in to cheap science programs, when I can get my weekly dose of awesome here :)
Agreed! I'm down to DVR episodes of PBS shows as the only stuff I watch on the big screen from TV, and Netflix for the rest. I'm finding myself turning that stuff off more and more because there's more interesting stuff on YT that is more up to date and unique. This is the future IMO.
It's not that the television science content has degraded, you've just out grown it. Television is largely a mass media thing, it has to appeal to the largest possible audience, or it can't pay the bills. That means unfortunately, that it has to appeal to the lowest common denominator. For science, that's essentially the uneducated, the scientifically illiterate. However someone who is interested in science, who actually watches those programs over the course of a few years, will after a point be somewhat better educated as a result. They see the same material covered several times at the same level, so the lessons get well learned. Finally the viewer is ready for more heady content, but none is to be had on television. That's where Isaac Arthur and company come in, to educate beyond that point.
Valid point Mr Cohen. I wouldn't say this content is unfriendly to the uneducated masses though. I will say it is more creative and better thought out than anything shown on corporate television media. Just look at the credits role at 25:28. That's an amazing feat for a platform like TH-cam. I think this channel should be picked up by a network like PBS. Heck I bet they would be able to generate an audience based on licensing content from past episodes of this channel.
Peter Cohen, when I was a kid in the 2000s there were a lot of those documentaries and shows that were meant for uneducated people with interest in science, but they actually taught things, I learnt a lot of things, but those shows are mostly gone. I live in Argentina, we have National Geographic, Discovery Channel, Animal planet and History Channel. NatGeo has become bloopers, magicians and drug contraband. Discovery is full of cars, motorcycles, survival realities, and magicians. Animal Planet is funny pet videos. History Channel is... well... aliens and trash hunters. This is why we are watching TH-cam, not just because we grew up, I look up documentaries from those days or new ones and they are still entertaining and educational.
Honestly, I think an untapped source of enthusiastic Mars astronauts is gamer dads. 30 months of isolation playing Stellaris and Rimworld without my kids yelling at me sounds like heaven, not a prison. ;)
I discovered Curious Droid 2 weeks ago. Great channel. You will probably enjoy Upward Bound playlist of this channel th-cam.com/video/JgxkilF5XUM/w-d-xo.html
Same I enjoyed the video ... New to hearing you for the first time I thought it was great that it was like Kripke from Big Bang Theory was narrating the video.
You'd expect the quality of these vids to take a hit from the high output volume. but, instead, they just keep getting better. This channel is just phenomenal..!
the BFR's sheer interplanetary tonnage capacity opens a whole lot of doors. You could stuff a lot of inflatable base into one of those things and a whole lot of simple robots to assemble it
Another great video! I love how frequently new videos are released on this channel. This morning I saw down to get some work done on the computer, and I knew it was the sort of mindless work that would allow me to listen to something at the same time (and pay attention to it). First thing that pops in my head is that I want to listen to whatever the new Isaac Arthur video is, so to youtube I go. Keep up the great work man.
Thanks Isacc Ive been in a rough patch lately and your videos always give me hope and inspire me to work hard to build a better world. Thank you , and keep up the good work !
Ambition is a very amazing factor. I believe Elon Musk's BFR will make a huge difference if it pans out to be a reliable platform. Having a rocket that can do all that Elon plans for will be a big impact on the possible options for Mars.
2:45 I echo the complement to Zubrin about _The Case for Mars_ ! I found it absolutely fascinating and very inspirational because here was an engineer taking a serious look at manned exploration of Mars.
I don't have a hard time understanding you at all, but I REALLY appreciate you don't blame other for your being able to understand your accent/speech impediment and make an effort to help people who find it difficult. I have a little bit of a similar impediment myself. I've worked hard to fix it, but I honestly can't hear it unless I hear a recording of myself. Hearing recordings of myself makes me extremely self conscious of it, kudos for you making videos despite it too. I really like your videos. ✌
I watch Japanese TV and movies with subtitles, but the dialog keeps me interested. So, your very interesting accent/brogue is no problem for this space cowboy.;)
This is in the top 5 best channels on TH-cam hands down. I recommend this channel to anyone I meet I think may have even the slightest inclination to astronomy.
Dude I love your lisp now. You just don't give a dang and keep on slugging. I mean dangit dude you're the absolute leader, worldwide, in the public presentation of these subjects, and not in a dumbed-down way either. Mad super props.
Glass or plastic that can handle the pressure difference? Why not grow plants in low pressure? Thin plastic bags with seeds in them, just inflate with CO2 and water.
Growing things at low pressure is totally doable. University of Guelph, Ontario has done experiments with growing plants at low pressure. The yields did not significantly decrease until the total partial pressure of O2 dropped below 7%. Plants were growing pretty nicely all the way down to 10% total atmosphere. The pressure inside most human spacesuit systems is around 20% atm (with 100% of the gas being O2). Thus, it's pretty reasonable to assume we could make a plant growth chamber with a 20% total pressure (composed of 100% O2), where people can comfortably walk around and tend the plants (after a little pre-breathing). Note that there is *no combustion hazard* with only 0.2 bar of O2... Things will burn exactly the same as on Earth (where there is also about 0.2 bar partial pressure of O2). The Apollo 1 problem was from using 120% atm of O2 (to keep the hatch closed at sea level they needed 1 full atm, and then another 20%... they used O2 to do all of this... bad idea). Using this approach no N2 gas would be needed. Most plants that use atmospheric N2 first have that N2 converted to NH4+ by bacteria. So these plants can (and often do) get their Nitrogen solely from salt nutrients in the soil or water. Low pressure study: Wehkamp et al. _Radish (Raphanus sativa L. cv. Cherry Bomb II) Growth, Net Carbon Exchange Rate, and Transpiration at Decreased Atmospheric Pressure and / or Oxygen._ Gravitational and Space Biology Volume 26 (1) Apr 2012.
Cheers! Interestingly,... that 7% figure is really close to the "Armstrong Limit" of 6.5% total atmosphere. At this point pilots can no longer used forced air systems to stay oxygenated and require a spacesuit to safely go higher. So, if we wanted to _really_ push the limit on this low pressure garden, we could go nearly down to the Armstrong Limit and have "scuba" tank type gear for the gardeners. I haven't done the math yet, so I have no idea what the engineering consequences for this might be. For sure though, the structural stress is *way* less at 7% atm (about 14 times less). So a plant-growth building made entirely of locally made, Martian plastic is probably reasonable.
Indeed, that option has grown in popularity as robotics has improved, and if we wait long enough the first 'manned mission' might be landing at a be constructed base needing little more than some tweaking and decorating. At the moment though we probably would be limited to early cargo placement.
I wouldn't expect us to start a colony on mars anytime sooner than some few decades from now, so i guess we have some time to evolve automation. Btw, awesome video as always
this channel is so brilliant, opening a conceptual door to outbound and really far-fetched notions as potential reality. Conquer the mind and you'll be one step closer to conquering space.
For a productivity bonus for a Mars mission would be to put extra rovers and robots on Mars that are controlled by the reroute Mars mission crew. They time lag would be reduced during transit and allow them to become familiar and work on their mission site.
Everyone blame Musk for thinking big and being overly optimistic. But viewers of this channel taking seriously harvesting the power of black holes and moving galaxies. Im dead :)
Golden horde The difference, of course, being the timescale. Musk wants to send people to Mars in 2022, which is admirable, but probably optimistic. The schedule for harvesting black holes is more like sometime before the death of the last stars.
hamstsorkxxor of course. But that joke was dope. Isaac was kidding pretty smart. If there will be some backing from NASA Elon could do that before 2024 I guess. If Boeng and ULA will not stay on the way of progress using its backers in Senate. With the technology of 60s USA were able to send people to mars. With all the progress in technology of recent years there are good chance to make it in time
Favel Konefka. ROI under 1% when the stock is holding steady above 300? After being around 150 just a year ago? All I can say is, your trolling skills require a bit more refinement.
Favel Konefka. Using the new movies as a reference. Yes. The microwave Canon was one of many government projects. The tumbler was also a government project. The material his suit is made out of was a government project. And by movie accounts Wayne Enterprises are burning through cash with no profit margin at least in cell phone R&D. Waynes personal trust fund are also said to be faltering.
I'd be pretty satisfied in this 26 month mission with just my crew and ability to write posts on forums / do art on laptop. See? All you need is just a hikikomori. We won't go insane! We are much better than these ordinary healthy people!
Looks like some new people dropping in who haven't heard much of Issac and a few who don't like your voice. I just want to say how much I like your voice, mate. Honestly, I find it easy to understand and actually quite cool. I hope the negative comments never get you down.
I hadn't watched Curious Droid in a while, but went back and saw the companion to this video, and I'm so glad I did. I have lots of new neat videos to ponder now!
Aaaah, remeber fondly the Pathfinder mission. Early teens. The landingwas televised live on the polish TVP1 public broadcaster. I convinced my granny to go from the countryside where we had a old black and white tv set to the apartment in the city with a proper colour tv. I was so tired... The images came through late in the night, but had to watch live the first images from Mars.!
Digamas ya it took me a couple episodes to get used to, but i find his accent super unique. It's really the interesting science talks that keeps me here though.
I have to say I enjoy it better when you partner with a channel but you each do you're own part separably, like you did this week. When you have multiple speakers in a video, it just comes across a bit awkward. Been a watcher for a long time and REALLY enjoy the episodes! Keep it up!
Isaac, you continue to "go above and beyond" with every new video. I'm especially looking forward to the upcoming Spaceports, Colonizing Alpha Centauri and Orbital Infrastructure videos.
I don't understand all this fuss about the manned Mars mission. Isn't it logical to establish permanent base on the Moon first? There are so many unknowns and risks associated with the Mars (let alone huge cost), which would be solved, and lot of lessons learned too, with the Moon mission.
Mandrak789 Need a location far enough that its not too convenient to comeback from, and not too close to where people can think, “we can go there whenever...” 30-40 years later... The commitment needed to reach the space age wasn’t met with the moon. If that was enough, we’d already have a moon base by now and probably asteroid mining too. But as rational as a moon base still is, public looses interest too fast in whatever causes don’t require enough commitment and doesn’t necessarily appeal to the most rational anyways.
read 'the case for mars'. Explains how they are so different that you would never go to the moon in order to get to mars anymore than you would prepare for a stay in Sahara by training in the Antarctic. Journey time aside mars is far safer and more fit for humans than the moon ever can be
I love the dream of Mars as much as the next person, but i think we should really focus on the moon first. Its nearer to earth so if something goes wrong the response window is significantly shorter, the moon is covered in He3 deposits for fuel refinement, we don't need to have EM shielding like we would for interplanetary distances so its easier tech wise, AND above all else it's easy to see from Earth so a city on the moon would be a HUGE symbol for people. Seriously, the world lost interest in the space race so damn quickly after the first 2 landings. A mars colonization attempt where you could never look into the night sky to see a symbol for the future would probably bore most people after the first landing in all reality. The moon is just an easier and more achievable goal which we should strive for first. MOON OR BUST!
Yeah all those things are great but the problem is it would be a lot harder to make a colony self sufficient on the Moon since it has so few light elements like nitrogen and carbon, elements you'd need for farming and metal refining.
Really, that's actually a good argument in favor of colonising the moon first. If it's actually harder, then anyone trained there will be far better equipped to handle Mars. And it gives us a harsh testing environment for tech to ensure it's ready for Mars.
Its harder in the sense that there's few resources there, that's not really a useful kind of hard. And the environmental challenges on the Moon are so different than Mars' that I'm not sure how much would be comparable. There are many places on Earth that are more similar to Mars than the Moon is.
The moon is a perfect staging area. It does lack carbon and nitrogen true but has everything else needed including water, no atmosphere and a easy escape velocity. You wouldn't even need a launch pad because you could launch from rails and there is plenty of power. The moon is the logical starting place.
Curious Droid and SFIA are natural collaborators. Great to see this collaboration. Both videos are A1 quality. Thanks folks! About the issues at hand, we probably really should be experimenting on folks with an algae, roots and fish based diet. Fleshing it out - Spirulina, potatoes/yams, krill and fish, maybe some mushrooms with a herb garden thrown in for taste and we might reach near a full cycle which just need energy thrown in. Spices might actually be compressed, when you think about it. Vinegar can be inorganically synthesised and used for tanginess. Interesting possibilities.
You should He has plenty of videos on the Fermi paradox, you can get his opinions on Alien life there. Grab a snake first though, he's got several decent sized videos on this topic.
my grandpa was an aerospace engineer for Honeywell from the early 60's to the mid 1990s. when confronted with a question of the practicality of a large project, his response almost always was "Columbus didn't come over in a rowboat, but he did bring one." his meaning was that you have to be prepared for what may come.
This is hilarious. I am a widow with three kids at home and I work a full time job. So being tired is my usual state of being. When I hear people talk about going to Mars or the moon, it makes me tired just thinking about everything they would have to do. Love your comment.
Well, I wrote it kind of facetiously. Frankly, I'm surprised more people didn't upvote it because it's a hilarious little comment. Just imagine some jaded teenager saying something like, "Yeah, Mars, whatever." Or comedian Steven Wright saying, "You get there and...it's just like standing on Earth...except everything sucks."
This is a great channel. Found this video and went to subscribe and realized I was already subscribed. You are the first channel I ever tried to subscribe to twice.
ampeyro Totally! Where better to perfect a closed loop life support system then in LEO. If something goes wrong rescue or evacuation is at worst hours away. A glitch at a Mars colony would almost certainly mean all hands lost.
We could also move that orbital infrastructure into orbit around the red planet. We can then cycle crews in and out of various forms of orbital infrastructure while tele-operate equipment on the surface with minimal lag. This could allow for the building of more complex surface infrastructure for use by landing parties. As long as we kept cycling people in and out regularly we could safely set the foundations for planetary colonization from orbit. We could test necessary equipment on-location and in real-world conditions without risking people's lives unnecessarily. All before ever setting foot on the red planet. It would be amazing.
Yesterday I watched in awe as falcon heavy set off for mars carrying a car. Surely this is the start of the holy grail of mars exploration. If a private company can send a car to mars it follows that resupply missions can just as easily be launched. Resupply, in tandem with recycling of resources and the use of water already on mars surely makes a manned mission a doable proposition. But I'm just a layman dreaming and hoping I will see this happen before I shuffle off to the great beyond. Thanks for your inspiring videos.
Once i was a enthusiast of Mars missions, now (and this is your fault Isaac...) i think we are wasting time and money that could be better used to stablished a space port on the Moon...
:) Yeah I tend to think Moon and asteroids are better expenditures, though honestly I tend to take - probably to no one's surprise - the attitude that 'do them all' is the best approach
I know Isaac, but let us be honest, we didn't need a Mars misson right now, except for morale, because we have far more to gain seting a base on the Moon right now, than get a few folks on Mars, stick a flagg and come back home.
we should do both plus floating cities on venus and various bases on asteroids and the big moons of Jupiter and Saturn - now the time line for all that will likely be a few centuries
Great video, thanks. Had to think what you meant by Mawze! No problem; it's only an accent, and doesn't detract from the quality of the presentation. Found this channel because of Paul's first part to this subject.
I think an ideal crew would be a 4-person polyamorous quad in a long-term, stable, child-free relationship - ideally one where the males have had vasectomies so that pregnancy isn't a concern. I may be a tiny bit biased though, since I've just described my own family...
No, there is definitely an accent there, Cajun perhaps or Deep, DEEP south weyah there are sipping mint julips ah do declare. I just turn the sound down, his accent is too distracting after a while; some accents are like that and i especially cant stand the New York or Baaaahstan accent, just way to distracting. Great videos otherwise.
I say shatter the planets for their juicy insides and build Dyson Spheres across the Galaxy. Why waste time? Let's get off this planet and leave it alone forever.
*cough* well according to my speech pathologist it really is an accent, and a couple others confirmed that to my surprise, I always said impediment too, though from where no one can figure out. The impediment doubtless caused it but as we've ground that away in recent months the peculiar voice has remained.
I already understand you a bit better than most of the people in my native tongue... its not that they speak unclear.. they speak bullcrap, your speech impediment fades very fast because you actually talk interesting things.! Keep up the great work! :D
I like the idea of colonizing Mars, but how do we keep from importing Earth problems like war and crime there? Is it just an inevitability of being human? Should we upfront and realistic and say certain people are simply not allowed? I personally find religion to be damaging to modern society. Would we be able to say "no devoutly religious people"?
I’d love for you to do a series or stand alone video on the effects of human intervention to volcanos. Drilling to ease pressure, doming Yellowstone, drilling and nuking a magma chamber, cooling a magma chamber with a heat exchanger, or some other mega structures you could come up with.
I think the greatest problem with space is technological obsolescence. For a time I remember one of the modules on the ISS not being used. The problem was the equipment was to old and out of date. They had to wait for NASA to launch new equipment to the station.
I just realized it's Thursday (it always sneaks up on me haha)! Awesome video. I always love educated discussions on where we currently are with plans for Mars and contemplating which direction we might go with manned/unmanned missions, colonization, etc. You have such fascinating ideas and your videos always give me tons of info I haven't heard, further insight into concepts I've briefly touched on before, and whether above or below my level of knowledge, you always explain things in a way I can understand. Thanks, cheers

How can I get a hold of the audio transcript of your videos?
I would say just use text to speech but with his unusual pronunciations it probably wound't work. Thankfully he provides close captions.
My favorite part was the stock video footage found by searching “happy family” and “couple argues divorce”
Love your videos Isaac. Cheers.
You'd expect the quality of these vids to take a hit from the high output volume. but, instead, they just keep getting better. This channel is just phenomenal..!
ah there it is, the recommendation to get a drink and a snack. I missed that. now it feels like a proper SFIA episode. :)

Only issue with inflatable base designs is radiation and possible tearing from sand storms.

Absolutely brilliant! As always! Thanks for uploading such thought provoking content Isacc!
If we further develop AI robots (the kind with arms and legs) we could leave them on the Martian surface to tend to things.
We should have parked the space shuttles in space when retireing them.

A space shuttle museum on the Moon would be nice too. It isn't too hard landing there right?

Im keen to see all your new and old content man. Great work!

This is in the top 5 best channels on TH-cam hands down. I recommend this channel to anyone I meet I think may have even the slightest inclination to astronomy.
My Favorite Rascally Rabbit Channel On TH-cam!!! 👽👽
Yeah, I have the undeniable feeling I'm watching a Big Bang Theory Episode where Kripke does all the talking.
Wascally Wabbit....
Dude I love your lisp now. You just don't give a dang and keep on slugging. I mean dangit dude you're the absolute leader, worldwide, in the public presentation of these subjects, and not in a dumbed-down way either. Mad super props.
Thursdays are my favorite day now.
This is my favorite channel on youtube. You're doing a great job.
Woo I needed my athursday fix real bad.
Is it just me, or does everyone else keep watching these videos again, and again and again. You are getting very close to 200,000 subscribers. :)
Glass or plastic that can handle the pressure difference? Why not grow plants in low pressure? Thin plastic bags with seeds in them, just inflate with CO2 and water.
Donald Hobson plants do better in higher pressures.
Im sure something will grow in those conditions, if not, try genetic modification.
Growing things at low pressure is totally doable. University of Guelph, Ontario has done experiments with growing plants at low pressure. The yields did not significantly decrease until the total partial pressure of O2 dropped below 7%. Plants were growing pretty nicely all the way down to 10% total atmosphere. The pressure inside most human spacesuit systems is around 20% atm (with 100% of the gas being O2). Thus, it's pretty reasonable to assume we could make a plant growth chamber with a 20% total pressure (composed of 100% O2), where people can comfortably walk around and tend the plants (after a little pre-breathing). Note that there is *no combustion hazard* with only 0.2 bar of O2... Things will burn exactly the same as on Earth (where there is also about 0.2 bar partial pressure of O2). The Apollo 1 problem was from using 120% atm of O2 (to keep the hatch closed at sea level they needed 1 full atm, and then another 20%... they used O2 to do all of this... bad idea).
Using this approach no N2 gas would be needed. Most plants that use atmospheric N2 first have that N2 converted to NH4+ by bacteria. So these plants can (and often do) get their Nitrogen solely from salt nutrients in the soil or water.
Low pressure study:
Wehkamp et al. _Radish (Raphanus sativa L. cv. Cherry Bomb II) Growth, Net Carbon Exchange Rate, and Transpiration at Decreased Atmospheric Pressure and / or Oxygen._ Gravitational and Space Biology Volume 26 (1) Apr 2012.
Faulx Eve I stand corrected and informed. Thank you.
Cheers! Interestingly,... that 7% figure is really close to the "Armstrong Limit" of 6.5% total atmosphere. At this point pilots can no longer used forced air systems to stay oxygenated and require a spacesuit to safely go higher. So, if we wanted to _really_ push the limit on this low pressure garden, we could go nearly down to the Armstrong Limit and have "scuba" tank type gear for the gardeners. I haven't done the math yet, so I have no idea what the engineering consequences for this might be. For sure though, the structural stress is *way* less at 7% atm (about 14 times less). So a plant-growth building made entirely of locally made, Martian plastic is probably reasonable.
This guy’s speech is unplacable. I like it.
What about sending robots with the cargo and materials first, letting them build and maintain the colony autonomously, and then sending the crew?
Indeed, that option has grown in popularity as robotics has improved, and if we wait long enough the first 'manned mission' might be landing at a be constructed base needing little more than some tweaking and decorating. At the moment though we probably would be limited to early cargo placement.
I wouldn't expect us to start a colony on mars anytime sooner than some few decades from now, so i guess we have some time to evolve automation.
Btw, awesome video as always
this channel is so brilliant, opening a conceptual door to outbound and really far-fetched notions as potential reality.
Conquer the mind and you'll be one step closer to conquering space.
I cometh to thy amazing episode..armed to the teeth with bottles of nectar and snacks!
For a productivity bonus for a Mars mission would be to put extra rovers and robots on Mars that are controlled by the reroute Mars mission crew. They time lag would be reduced during transit and allow them to become familiar and work on their mission site.
Cool! You are 2 of my favorites!
I love the idea of spending 2+ years away from everyone. Solo mission please, I offer as tribute!
Keep doying this Isaac!
I love how you narrate, dramatic and informative. Let's go to Mars!
Everyone blame Musk for thinking big and being overly optimistic. But viewers of this channel taking seriously harvesting the power of black holes and moving galaxies. Im dead :)
Golden horde
The difference, of course, being the timescale. Musk wants to send people to Mars in 2022, which is admirable, but probably optimistic. The schedule for harvesting black holes is more like sometime before the death of the last stars.
hamstsorkxxor of course. But that joke was dope. Isaac was kidding pretty smart. If there will be some backing from NASA Elon could do that before 2024 I guess. If Boeng and ULA will not stay on the way of progress using its backers in Senate. With the technology of 60s USA were able to send people to mars. With all the progress in technology of recent years there are good chance to make it in time
Favel Konefka. So Elon Musk is Batman by your definition.
Favel Konefka. ROI under 1% when the stock is holding steady above 300? After being around 150 just a year ago?
All I can say is, your trolling skills require a bit more refinement.
Favel Konefka. Using the new movies as a reference. Yes. The microwave Canon was one of many government projects. The tumbler was also a government project. The material his suit is made out of was a government project.
And by movie accounts Wayne Enterprises are burning through cash with no profit margin at least in cell phone R&D. Waynes personal trust fund are also said to be faltering.
I enjoy how your videos are longer and in depth
I'd be pretty satisfied in this 26 month mission with just my crew and ability to write posts on forums / do art on laptop.
See? All you need is just a hikikomori.
We won't go insane! We are much better than these ordinary healthy people!
Temp Name but to apply for a mission you would need to interact with people. And here lies the problem
Just don't bring human-despising hikikomories onboard and the mission will be fine. Всё гениальное просто.
Looks like some new people dropping in who haven't heard much of Issac and a few who don't like your voice. I just want to say how much I like your voice, mate. Honestly, I find it easy to understand and actually quite cool.
I hope the negative comments never get you down.
Maaus
Maws
Malls..
mowas
he speaks English exactly as many swedes do. Except this is thicker.
what is mas? why no love heart for us?
I hadn't watched Curious Droid in a while, but went back and saw the companion to this video, and I'm so glad I did. I have lots of new neat videos to ponder now!
I'm now on my eight video in a row. Do I keep grabbing a drink and a snack?
Probably only if you want to alternate between snacking and a treadmill each episode :)
Emphatic Yes
Aaaah, remeber fondly the Pathfinder mission. Early teens. The landingwas televised live on the polish TVP1 public broadcaster. I convinced my granny to go from the countryside where we had a old black and white tv set to the apartment in the city with a proper colour tv. I was so tired... The images came through late in the night, but had to watch live the first images from Mars.!
Mawz
to mawz in fou yeeus
Lol, yeah. This is the first time I have heard someone say Mars like that. Very distracting.
"Mauwzz"
Lucas Froissart lol I love his speech.
Digamas ya it took me a couple episodes to get used to, but i find his accent super unique. It's really the interesting science talks that keeps me here though.
I have to say I enjoy it better when you partner with a channel but you each do you're own part separably, like you did this week. When you have multiple speakers in a video, it just comes across a bit awkward.
Been a watcher for a long time and REALLY enjoy the episodes! Keep it up!
Where's my space bros and sisters that was already subscribed to both here and Curious Droid already before the colab?
Beautifully made, I come in peace, sent by the Curious Droid:)
Yes! A new video :)
ARTHURSDAY..... The BEST day of the week!!! Thank you Isaac!!! Just brewed a pot of coffee and I'm ready.. Let's GO!!
when is the next one! I need 3 per a week!
Yeah, thursday is the new start of the weekend
years of watching elmer fudd has prepared me for this guy.
Isaac, you continue to "go above and beyond" with every new video. I'm especially looking forward to the upcoming Spaceports, Colonizing Alpha Centauri and Orbital Infrastructure videos.
I don't understand all this fuss about the manned Mars mission. Isn't it logical to establish permanent base on the Moon first? There are so many unknowns and risks associated with the Mars (let alone huge cost), which would be solved, and lot of lessons learned too, with the Moon mission.
Mandrak789 Need a location far enough that its not too convenient to comeback from, and not too close to where people can think, “we can go there whenever...” 30-40 years later...
The commitment needed to reach the space age wasn’t met with the moon. If that was enough, we’d already have a moon base by now and probably asteroid mining too. But as rational as a moon base still is, public looses interest too fast in whatever causes don’t require enough commitment and doesn’t necessarily appeal to the most rational anyways.
read 'the case for mars'. Explains how they are so different that you would never go to the moon in order to get to mars anymore than you would prepare for a stay in Sahara by training in the Antarctic. Journey time aside mars is far safer and more fit for humans than the moon ever can be
I love that every thursday I return, I see the subscriber number a few thousands higher than last time.
I love the dream of Mars as much as the next person, but i think we should really focus on the moon first. Its nearer to earth so if something goes wrong the response window is significantly shorter, the moon is covered in He3 deposits for fuel refinement, we don't need to have EM shielding like we would for interplanetary distances so its easier tech wise, AND above all else it's easy to see from Earth so a city on the moon would be a HUGE symbol for people. Seriously, the world lost interest in the space race so damn quickly after the first 2 landings. A mars colonization attempt where you could never look into the night sky to see a symbol for the future would probably bore most people after the first landing in all reality. The moon is just an easier and more achievable goal which we should strive for first. MOON OR BUST!
Yeah all those things are great but the problem is it would be a lot harder to make a colony self sufficient on the Moon since it has so few light elements like nitrogen and carbon, elements you'd need for farming and metal refining.
Really, that's actually a good argument in favor of colonising the moon first. If it's actually harder, then anyone trained there will be far better equipped to handle Mars. And it gives us a harsh testing environment for tech to ensure it's ready for Mars.
Its harder in the sense that there's few resources there, that's not really a useful kind of hard. And the environmental challenges on the Moon are so different than Mars' that I'm not sure how much would be comparable. There are many places on Earth that are more similar to Mars than the Moon is.
The moon is a perfect staging area. It does lack carbon and nitrogen true but has everything else needed including water, no atmosphere and a easy escape velocity. You wouldn't even need a launch pad because you could launch from rails and there is plenty of power. The moon is the logical starting place.
Its a logical mining/resource area for Earth orbital space but I don't think its a good place for a colony.
Two of the most awesome channels do a collaboration! Amazing:)
Drink every time he says "Mmaws"
It was a wrover not a pawson
No need for CC, I understand just fine. Well done. Been a Curious Droid subscriber for a couple of years, glad I found your channel.
I'm new. Can someone explain this guy's accent? It has me stumped xP
Speech impediment.
He has the Elmer Fudd Wascally Wabbit Accent! ;)
@@calvingreene90 I have a family member with the same thing. It's a speech impediment.
Russell Solomon literally thought the same ha I know that’s wrong to laugh but I couldn’t help it. Mauls
Curious Droid and SFIA are natural collaborators. Great to see this collaboration. Both videos are A1 quality. Thanks folks!
About the issues at hand, we probably really should be experimenting on folks with an algae, roots and fish based diet. Fleshing it out - Spirulina, potatoes/yams, krill and fish, maybe some mushrooms with a herb garden thrown in for taste and we might reach near a full cycle which just need energy thrown in. Spices might actually be compressed, when you think about it. Vinegar can be inorganically synthesised and used for tanginess. Interesting possibilities.
Why it sounds like he's about to disclose existence of aliens, when he start every sentence.
You should He has plenty of videos on the Fermi paradox, you can get his opinions on Alien life there. Grab a snake first though, he's got several decent sized videos on this topic.
Gosh man! Grabbing a snake sounds nasty, don't listen to this guy :D Nevertheless watch those videos, they are awe inspiring.
What are alines?
beaconrider under development “aliens"
my grandpa was an aerospace engineer for Honeywell from the early 60's to the mid 1990s. when confronted with a question of the practicality of a large project, his response almost always was "Columbus didn't come over in a rowboat, but he did bring one."
his meaning was that you have to be prepared for what may come.
Meh. Mars is way over there, and I'm really tired....
This is hilarious. I am a widow with three kids at home and I work a full time job. So being tired is my usual state of being. When I hear people talk about going to Mars or the moon, it makes me tired just thinking about everything they would have to do. Love your comment.
Well, I wrote it kind of facetiously. Frankly, I'm surprised more people didn't upvote it because it's a hilarious little comment. Just imagine some jaded teenager saying something like, "Yeah, Mars, whatever." Or comedian Steven Wright saying, "You get there and...it's just like standing on Earth...except everything sucks."
This is a great channel. Found this video and went to subscribe and realized I was already subscribed. You are the first channel I ever tried to subscribe to twice.
Call me a coward but I'd rather perfect self-sustaining space habitats before flying to another planet on a glorified trailer.
ampeyro Totally! Where better to perfect a closed loop life support system then in LEO. If something goes wrong rescue or evacuation is at worst hours away. A glitch at a Mars colony would almost certainly mean all hands lost.
We could also move that orbital infrastructure into orbit around the red planet. We can then cycle crews in and out of various forms of orbital infrastructure while tele-operate equipment on the surface with minimal lag. This could allow for the building of more complex surface infrastructure for use by landing parties. As long as we kept cycling people in and out regularly we could safely set the foundations for planetary colonization from orbit. We could test necessary equipment on-location and in real-world conditions without risking people's lives unnecessarily. All before ever setting foot on the red planet. It would be amazing.
Well you could argue that the saturn v was a glorified trailer too.
Your phone has more computing power than that thing...
I fully agree with the thanks to KS.Robinson. Greatest writer i've ever read.
Yeahhhh!
Thank you Isaac for all your hard work,it is a joy to watch. Just splendid!
Maws is my fav planet
Yesterday I watched in awe as falcon heavy set off for mars carrying a car. Surely this is the start of the holy grail of mars exploration. If a private company can send a car to mars it follows that resupply missions can just as easily be launched. Resupply, in tandem with recycling of resources and the use of water already on mars surely makes a manned mission a doable proposition. But I'm just a layman dreaming and hoping I will see this happen before I shuffle off to the great beyond. Thanks for your inspiring videos.
Go Mows!
Mows for Mowsians!
Snacks and soda ready. Time for my real weekly treat here.
Once i was a enthusiast of Mars missions, now (and this is your fault Isaac...) i think we are wasting time and money that could be better used to stablished a space port on the Moon...
:) Yeah I tend to think Moon and asteroids are better expenditures, though honestly I tend to take - probably to no one's surprise - the attitude that 'do them all' is the best approach
Yes.. he did that to me too.. so much so that I feel the urge to dust off my 3d software and start making graphics for him. :)
I know Isaac, but let us be honest, we didn't need a Mars misson right now, except for morale, because we have far more to gain seting a base on the Moon right now, than get a few folks on Mars, stick a flagg and come back home.
If Elon Musk somehow manage pull all his plan of (somenthing that i doubt...), it will be awesome, tough.
we should do both plus floating cities on venus and various bases on asteroids and the big moons of Jupiter and Saturn - now the time line for all that will likely be a few centuries
Great video, thanks. Had to think what you meant by Mawze! No problem; it's only an accent, and doesn't detract from the quality of the presentation. Found this channel because of Paul's first part to this subject.
What is that accent? was difficult to perceive for me.
I think an ideal crew would be a 4-person polyamorous quad in a long-term, stable, child-free relationship - ideally one where the males have had vasectomies so that pregnancy isn't a concern.
I may be a tiny bit biased though, since I've just described my own family...
I think the Shakelton expeditions are a clear and final answer to your concerns over psychology.
For Maws sake, what the hell is that accent?
Robert Kalinič is not an accent it's a a speech disability
Do you know what exactly?
Robert Kalinič i think its rhotacism. His "R" sounds more like a "W". Nevertheless, not an issue for alot of viewers including me.
I believe the narrator would be greatly helped by practicing this video to treat rhotacism: th-cam.com/video/rcQV-jLsA1g/w-d-xo.html
No, there is definitely an accent there, Cajun perhaps or Deep, DEEP south weyah there are sipping mint julips ah do declare. I just turn the sound down, his accent is too distracting after a while; some accents are like that and i especially cant stand the New York or Baaaahstan accent, just way to distracting. Great videos otherwise.
First time watching your channel. You rock!
I say shatter the planets for their juicy insides and build Dyson Spheres across the Galaxy. Why waste time? Let's get off this planet and leave it alone forever.
Sycon1224 Well we need a pit stop
You had me at 0:31. Visiting from Curious Droid and you’re coming in loud and clear! Such a cool channel - you’re newest subscwhyba has awived!!
I’ll give you $50 if you can say
“Peter Piper Picked a Peck of Pickled Peppers” 5 times fast
With the “R”s
Great video about Maws, loved it!
Whats with the accent?
Mister Doctor its a speech impediment
It's the accent of science!
*cough* well according to my speech pathologist it really is an accent, and a couple others confirmed that to my surprise, I always said impediment too, though from where no one can figure out. The impediment doubtless caused it but as we've ground that away in recent months the peculiar voice has remained.
It's absoowrd!!
I don't care what it is, I think it gives you character and doesn't get in the way of the content at all.
I already understand you a bit better than most of the people in my native tongue... its not that they speak unclear.. they speak bullcrap, your speech impediment fades very fast because you actually talk interesting things.! Keep up the great work! :D
I don't notice it anymore and forget until I read comments.
I like the idea of colonizing Mars, but how do we keep from importing Earth problems like war and crime there? Is it just an inevitability of being human? Should we upfront and realistic and say certain people are simply not allowed? I personally find religion to be damaging to modern society. Would we be able to say "no devoutly religious people"?
I’d love for you to do a series or stand alone video on the effects of human intervention to volcanos. Drilling to ease pressure, doming Yellowstone, drilling and nuking a magma chamber, cooling a magma chamber with a heat exchanger, or some other mega structures you could come up with.
Was already an avid fan of both channels, very happy to see a collaboration
I think the greatest problem with space is technological obsolescence. For a time I remember one of the modules on the ISS not being used. The problem was the equipment was to old and out of date. They had to wait for NASA to launch new equipment to the station.
I just realized it's Thursday (it always sneaks up on me haha)! Awesome video. I always love educated discussions on where we currently are with plans for Mars and contemplating which direction we might go with manned/unmanned missions, colonization, etc. You have such fascinating ideas and your videos always give me tons of info I haven't heard, further insight into concepts I've briefly touched on before, and whether above or below my level of knowledge, you always explain things in a way I can understand. Thanks, cheers
