    Here's the link again to Part 1: ua-cam.com/video/Pv7aigOzQKo/v-deo.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.

      Domes have poor radiation shielding.

    • @davidhollenshead4892
      @davidhollenshead4892 6 років тому +5

      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 :)

    • @UpcycleElectronics
      @UpcycleElectronics 6 років тому +8

      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.

    • @panpiper
      @panpiper 6 років тому +26

      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.

    • @UpcycleElectronics
      @UpcycleElectronics 6 років тому +15

      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 UA-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.

    • @lncerante
      @lncerante 6 років тому +16

      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 UA-cam, not just because we grew up, I look up documentaries from those days or new ones and they are still entertaining and educational.

    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.

    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've never got the "social isolation" aspect of it. So what if there's a time delay when sending messages? Is that supposed to freak anyone out? Back in the days of sail, people would routinely set out on missions in which they wouldn't see anyone outside the crew for months, if not years, not even to send letters. If they did have family back home, and could send letters, it would be months before they could expect any sort of reply. Even in the modern era we do a lot of communication through texts, Facebook, etc., where people might not respond for minutes or hours, so an established 8-minute delay really shouldn't be any cause for concern, so long as the crew of the ship was of a sufficient size that they didn't fee *completely* isolated. There are also plenty of introverts out there with little or no human interaction by choice.

    • @faulxeve6590
      @faulxeve6590 6 років тому +6

      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.

    • @faulxeve6590
      @faulxeve6590 6 років тому +1

      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.

    After reviewing several videos from both Isaac Arthur and other sources, I'm baffled by this push to go to Mars in the 2020s. We are obviously not ready. We're still using a 1990s-style International Space Station, with no clear possibility of replacement with a more advanced design on the horizon. We lack any substantial orbital or lunar infrastructure to use as a platform to launch to more audacious interplanetary goals. We don't have a Von Braun-style rotating wheel space station in low Earth orbit, let alone anywhere else.
    Exposing astronauts to dangerous solar radiation and cosmic rays and also to prolonged zero-gravity with no hope of relief, would be irresponsible. Given Earth's current space technology and rockets, it would easily take months to travel one-way between Earth and Mars. In a spacecraft with no compensatory structure to mitigate radiation, rays and zero-g in the interplanetary void, such an ambitious mission is not practical, feasible, safe, or therefore humane.
    Elsewhere in Issac Arthur's videos, he mentions a concept first developed by Edwin "Buzz" Aldrin of Apollo 11 fame: the Aldrin Cycler, aka the Earth-Mars Cycler, aka the Aldrin Castle. Essentially, since the trajectory to or from Mars takes months, Aldrin proposed a unique scheme is which a rocket is attached to an advanced space station whose orbit to situated such that the station/ship revolves (indirectly) around render-vous points for Earth and Mars in a never-ending circuit ("Cycler"). This allows the station to house astronauts in a more humane environment as they journey between planets. Arthur included images of a rocket ship with a Von Braun-style "spinning wheel" space station attached to show how such a Cycler/Castle could be structured to provide journeying astronauts with (simulated centrifugal) gravity. No doubt such a station/ship habitation ring could be covered with ice or lunar regolith-concrete to shield the inhabitants against interplanetary hazards.
    As Arthur said, a Mars mission would not last days like the Apollo missions did, nor would it be practical just to send a few astronauts there at a time. If we sent a space station to Mars orbit to serve as a long-term base, and facilitated the long-term use of at least one Aldrin "Castle" to act as a ferrying conductor between Earth and Mars, we would then have a practical or humane means of carrying out the mission. Therefore, Mars will remain an impractical pipe dream until there is a multi-national effort to: (1: build and practically operate a new ISS in the form of a Von Braun-style wheel in Earth orbit, followed by (2: building and operating a similar station in lunar orbit and/or the LaGrange points, followed by: (3: developing a wheel-station design that will include amenities and materiel self-sufficiency (including on-board hydroponic gardens that can feed the inhabitants in perpetuity) so that it can survive in isolation for at least a year or more, and followed by: (4: development of a comprehensive robotic mission to Mars to fabricate/construct a base there to be completed and tested before astronauts arrive, followed by: (5: development of Aldrin "Castle" station-ships and support craft to establish both the interplanetary ferry-station and a mission station for Mars orbit.
    Until we can do these things and do them reasonably well, we're not taking this idea of a manned exploratory mission to Mars seriously.

    • @isaacarthurSFIA
      @isaacarthurSFIA  6 років тому +1

      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 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.

    • @MarsStarcruiser

      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.

    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!

    • @massimocole9689
      @massimocole9689 6 років тому +16

      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.

    • @Kirhean
      @Kirhean 6 років тому +10

      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.

    • @massimocole9689
      @massimocole9689 6 років тому +9

      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.

    • @TheEvilmooseofdoom
      @TheEvilmooseofdoom 6 років тому +10

      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.

    • @massimocole9689

      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.

I admire the decision to not change for the sake of others... you do you man. 2. adding consideration for others is also a positive trait that seems to be a nearly extinct trait these days and should be cherished and celebrated. 3. as I continued to listen to the video I began to find it kind of endearing and unique. 4. Mr. Arthur is ON POINT, the data and thoughts on the information all checks out and is presented in an engaging way which is key to any presentations success. 10/5 stars Mr. Arthur, I am now a subscriber and look forward to binging videos for the next week or so lol.

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.
