An O'Neil cylinder would be cool, but at Blue Origin's pace of development, humans will have evolved to beings of pure energy and the sun would be a burned out white dwarf by the time they can make one and thus humans wouldn't need them...

[antonnym]

An O'Neill cylinder that generates Mars gravity would be 640 meters/2, 100 feet in diameter. Even so, you make a good point about rotational simulated gravity as opposed to real gravity. The cylinder has to rotate once ever 58 seconds to have Mars-approximate gravity. The biggest difference between rotational and real gravity would be trajectory effects on moving objects due to the Coriolis force.

Can't help but also look at the track record of accomplishments by SpaceX vs Blue Origin. Elon is far ahead, while BO still has yet to reach orbit! Get off your yacht and get to work Jeff!

[robertjung]

Bezos needs to reach orbit first... it's beyond comprehension how is BO considered as a big player among space companies while they did not reach orbit yet...

[ooo-its]

Absolutely, O'Niel cylinders are a no-nonsense path to off-world habitation and industry.
Build the frame, then mine the moon to fashion as much as possible in orbit.

We must explore all options not one or another

[kingmasterlord]

2:00 we have inexhaustible resources available to us, we simply are forced to use finite ones by those who profit from their sale.

we have algae that secretes biodiesel, no refinement. theres a Canadian cedar who's sap is chemically functionally identical to kerosene, we got the various uses of hemp and kelp. we got spider silk produced by yeast and mycelium is a newly explored material between wood and concrete. we can grow most of what we need already.

Technical note: you have been talking about O’Neal Cylinders while illustrating a Stanford Torus.

[DarrylConliffe]

Hey, let's first get back to the Moon!

[JoesPalace]

In a groundbreaking study published Aug. 7 in Science Advances, researchers from the University of Chicago, Northwestern University, and the University of Central Florida have proposed a revolutionary approach towards terraforming Mars. This new method, using engineered dust particles released to the atmosphere, could potentially warm the Red Planet by more than 50 degrees Fahrenheit, to temperatures suitable for microbial life -- a crucial first step towards making Mars habitable

[marcmelvin]

I like that both Musk and Bezos have the imagination and the ambition to at least Do Something, instead of coming up with reason after reason for why neither of their options is viable and shouldn’t even be attempted. It astonishes me that a site like this, presumably attractive to people who, like myself, are fascinated by space and space travel and space living, has so many people whose natural reaction is to denigrate either or both of those gentlemen, or to dismiss their ambitions and efforts as pointless or impossible, rather than applauding their efforts, or suggesting better ways to do what they are doing, or accepting that there is more that we don’t know than what we do, and that this is going to be damned hard, and that maybe the same spirit of exploration and the chance to struggle for something is enough reason to do it. Let’s go to Mars, and start on that colony, and while we’re at it, let’s start planning for how to make Bezos’ in-space habitat, and while we’re at it, let’s cheer for the Russians eyeing Venus, and even do some research on some day producing a global orbital ring so that LEO becomes easily attainable. In the meantime, kudos to those who had something useful or positive to say.

[garylester]

I think we will build both, but personally I'm more arrtacted to ships than globular dirt or orbital sewer tubes.

With ships you can escape problems with mobility, also explore and learn, and find resources where ever they are.

Also they wouldnt have to be so collective, could be individualistic and avoid innumerable Schitt Heads.

I've lived on ships before, they can be quite pleasant.

[DeeyaGarg]

One step at a time! Both require the same first step, cheap access to LEO.

[greghouston]

Nice piece Angry! For those interested The Mars Society annual conference began today (Thursday 8 August and runs through Sunday the 11th). Much will be available here on You Tube.

[Verpal]

I think the main problem of Mars is whether Martian still counts as human in long term, like, very long term, or will human just create a rival intelligent species out of thin air?

[SuperTrainStationH]

I think significantly smaller scale orbital settlements are too often overlooked, I think they could be essential in the development of colonies both on planet surfaces and for future large scale (O’Neill cylinder type) colonies. My concern with O’Neill cylinders would be that a society organized enough to construct one could potentially by necessity be authoritarian in nature, but the recent concept of spinning a “loose” meteorite made of small particles and catching the debris in something of a spherical net that is rotated in order to form the inner surface of a medium to large scale orbital habitat may make such a project relatively scalable.

[kanukistani]

I think both will happen, but it's much easier to dig into the moon or Mars than build an O'Neill cylinder from scratch. From that base, you can do mass drivers and remote asteroid mining, and only then build space stations. Eventually most people will live in space, but not in our lifetime.

[alvermillioncranky]

1:50 I'd go in a heartbeat to Mars and I'm 71 now. Bezos lives in his own little bubble. 10:00 Cylinder rotation should be 0.32-0.35 Revs/Min as this ensures an increase in strong growth. Growth on Mars will likely allow for height increases.

[bjturon]

Excellent video with great graphics! Wonderful thumbnail. There is a third way, colonizing an asteroid, a medium size one would have a lot of material, even water an organics, and you could spin it to create gravity. The Belters in "The Expanse" lived in large asteroids.

[michaelfink]

Interesting video, Angry. Overall, I agree that Mars colonisation, while extremely difficult, probably has the edge. One advantage of space stations, at least those in Earth orbit, that I think you didn't mention is the short travel and communication time to Earth. This will be important for resupply, transfer of people and emergency evacuation. I anticipate that we will have both options in the far future. I look forward to SpaceX and Blue Origin (hard to take the latter too seriously until they have managed an orbital mission) and other companies making progress towards these goals.
