    PBS Spacetime on colonizing Venus


    The 5 best options for colonizing in our solar system are:
    The moon

    The moon
    Gravity: 1/6 that of earth
    Air pressure: none
    Temperature: extreme (253 in sun, -253 in shade)
    - Why go - a place to launch to other places
    Orbiting at 2288 mph (3683 kph) - significant boost
    Advantages: Instant communication with Earth
    Good place to learn how to colonize where Experts are available 24/7
    Advantages: Lighter gravity means we could build bigger there
    Advantages: could dome over craters to create housing
    Advantages: water ice in some pole craters

    One place we have talked a lot about is Mars
    Gravity: Just over 1/3 (38%)
    Air Pressure: .6% if Earth’s
    Temperature: 70 in day (20C), -100 at night (-73C)
    Why go: Most comfortable temperature-wise and gravity-wise, but pressure is still abysmal
    Down-side: Thin atmosphere means not enough to support life but enough to make landings difficult.
    Terraforming option - most potential for terraforming. Melting ice caps could pump CO2 into the air and thicken the atmosphere as well as warm the planet

    Gravity: 13% of Earth’s
    Air pressure: barely exists - mostly oxygen
    Temperature: -260F -160C
    This seems like a swing and a miss, but there’s something interesting under the surface of Europa
    Tidal heating causes a sea of liquid water beneath the surface.
    One of the best options for finding life in the solar system
    Underwater habitats might be the answer.
    Downside: radiation carried by Jupiter’s magnetic field would pose an issue

    Gravity: 13% of Earth’s
    Air pressure: 1.5x that of Earth
    Temperature: -290F, -179C
    Of all the places in the solar system, Titan’s air pressure is most like Earth’s
    You could just walk around on the surface without a suit, except for the fact that it’s so cold methane flows in rivers.
    Could use the methane for fuel

    But I promised something controversial, and here it is, my personal favorite option for colonizing another planet… Venus.

    Gravity: 91% of Earth’s
    Air Pressure: 100x that of Earth
    Temperature: 872F, 467C

    Now I know what you’re saying, you’re saying Joe, that only meets one of the three criteria, how can you possibly pick that as your number one?

    Because those numbers are for the planet’s surface. Up in the clouds, it’s a different story.

    Venus’ air pressure is insane. On the surface, it would crush you like a soda can. But about 50 kilometers up in the atmosphere, it’s about the same as here.

    Which means that just like a ship can float on top of the water, we could build colonies that float on the upper atmosphere of Venus.

    It would still be hot, but manageable.

    And I know people will always say, but what if you fall? Or if you drop something, you’ll never get it back. Well, I go back to the ship on the sea analogy. If you fall off the boat, you’re likely to drown. If you drop your phone over the side, you’ll never see it again. But we still have cruise ships carrying thousands of people and entire navies floating around out there.

    Plus the communication time would be smaller than anywhere else.

    How are you going to suggest Venus and not make a reference to Cloud City? Was it just too easy of a lay up?

    I mean I know there was a valid fear of nuclear war but give me Cold Wars over hot ones any day of the week. Especially when the battles include walking on the moon and chess tournaments.

    Reliance on perpetual buoyancy above an acid is suicidal! Even boats that float on water can be dry docked on our planet when needed. Where might this happen on Venus? The idea is completely ludicrous!

    If we spend even ONE billion years on this rock and this rock only, I think every other point made in this video is moot. By the way, as one of Arthur's viewers, I now know that the number 1 place you would colonize is a place you build yourself. You can probably steer it to avoid slow moving dangers like asteroids, make it just as big as you need it, control all temperature, gravity and air pressure aspects and best of all - it would cost a fraction of any of the options presented in this video :)

    I'd add to your list "strategic". So, like the moon (as you mentioned), but places like Ceres too

    The top 5 places to colonize: 1-LaGrange point stable places for human habitats; 2-the Moon(the most likely eventual winner); 3-Titan, where you'd just need a hermetically insulated jacket and a breathing mask; 4-the ocean, where we still don't reside; 5-Mars, which has the fatal flaw of having no power source to keep us alive and warm...

    We can not go to venus to protect ourselves from the red giant sun because it will burn to crisp before earth , ( and because of the acid rain)

    Joe Scott - rewatched because someone on Quora asked about Saturn. Surprisingly, Saturn, in the cloudtops, at near Earth normal pressure has closer to Earth normal gravity than Venus. But the temperature problem may be worse . . . it's very cold.

    what are the chances that the gravity here on earth before are much less compared to now thats why ancient people have built the pyramid of giza or other megalithic structures with ease and accurately?

  • Robert Cooper

    Hmmm sulphuric acid... sounds great!! My vote is for the moon as a launching base. Manufacturing on the moon, yes!!! Engineering in a weightless environment would be a challenge at first, but we would wonder how we ever did it in a gravitatorial environment. There is limitless energy to be harvested. And a vacuum to create a whole new set of alloys... resources by the asteroid ☄️... yep 👍 space is the place...

    Biggest benefit of Venus (in my opinion): You could spend years there, and still return to earth without significant problems (other than a 10% weight gain).If your body acclimates to Mars over 2-3 years, it will be a MASSIVE effort to get you back to a shape in which you can function on earth again.So if you're going there long-term, there's effectively no going back.So if you want to colonise a place with specialists (and build up a self-sustaining system there), Venus is the better option. It would be comparable to people working on an oil rig.

    The Salton Sea is at 1 atm of pressure, 20.9% oxygen. That water is liquid, albeit contaminated with salts. Scientist should focus on making the worst parts of this planet habitable, rather than going out into space where FEWER people will be able to go.

    We should try to colonize the deserts of the Southwest.If you can't make it there, you won't have a chance at surviving in space.

  • Patrick Howard

    The only way to ensure that a colony on Mars lives is to build an orbiting satellite (a torus - 2 miles in Diameter.) that can produce lots of food, oxygen, water... And be radiation-free... spinning, with near Earth-gravity... And get it to an orbit around Mars. - So the colonist can rotate off the surface to a place where they can R&R... And have the necessities close... Not to mention the 'life-boat'... If needed. All other scenarios will result in DEAD colonists. (I know, I'm a pessimist... But... Every colonist on Mars, will rely on the governments on the Earth to keep them supplied with food and oxygen... Dead.)

    Well I think that you missed the best one. Earth. We can build islands around the habitable zones of earth through the oceans, deserts, polar and mountain ice caps. We can irrigate the desert, regreen this planet, create abundant life in the oceans and at the poles. We are a very adaptive and creative species, we humans. After earth, the moon is my top choice. There is a whole lot we have yet to accomplish. We can do better. We can turn our ICBM's towards world ending comets and asteroids, thereby saving the planet with our magnificent powers rather then destroying it with our ignorance.

    If the sun expands and swallows up the inner planets, won't that mean that it will be closer to the outer planets making some of the moons more viable?

    I don’t think we are capable of building a floating city on another planet never mind earth. Even if we can the temperature would still be 30 to 40 digress up there

    I've always thought that Mars lost its atmosphere because it's core cooled. Wouldn't that mean that, if we released gas around Mars, it would just escape?

    Mercury is actually the closest planet, on average, to ever planet in the solar system.

  • 911LookuptheLavonAffair

    So Titan's problems are lack of gravity, and low temperatures... but the air pressure is great. In that case, how about the idea of terraforming Titan? Titan, being a gas giant moon, is in the vicinity of the asteroid belt. Perhaps some large asteroids could be moved onto a collision course with Titan, quickly increasing the mass (and therefore the gravity) of the planet. Then, the temperature might be able to be modified by engineering greenhouse gas production facilities that produce greenhouse gasses many times more potent than CO2 and release them into Titan's atmosphere.Seems like Titan might be a good candidate for terraforming projects in the long-term, eh?

  • 911LookuptheLavonAffair

    The problem with melting Martian polar ice caps to release CO2 into the atmosphere to warm up the planet is that the added atmosphere might just get blown away by solar winds. The Martian atmosphere is not as durable because it doesn't have a magnetic field.We should just focus on establishing a permanent base there before we even think about terraforming it. Once the base (or small colony) gets going, people will have more of an incentive to invest the resources into a terraforming project and figuring out how to make it work.
