As long as ego's are kept in place it could be a successful one. But we will never know. It's a one way trip. And that is another point, is Earth really willing to spent trillions to send a rock with a few people on a one way trip to alpha centauri. I posted this idea yesterday on a "Should we" do something way beyond our capabilities video so I had a night to think about it, the only way I can see everyone getting on board with that kind of project and sustaining enthusiasm for a decade or more is to put the Asteroid in orbit around the Moon so everyone can see it every night as the work is done. But even those things are impossible right now. But a asteroid is the cheapest way I think, and safest. 🍁 (I'm also thinking double leg amputees' a primary candidates for Missions inside the solar system, lets see if they make a video about that in 24 hours).

Coring an asteroid (because you said "encasing") is a very difficult prospect. First of all, they're not like a mountain, where Joe Miner can go pickaxe his way through, then using square set beams, they can support massive amounts of weight, so that requires heavy duty equipment able to core through various layers of various things from ice to metal to plain rock. Whilst in space. Back on earth, passing through various layers of varied density is what kills most drills. Experienced machinery operators are chosen based on their ability to know when to either torque or speed through something, imagine doing that in space where... you'd need something like a TBM to work, a TBM that's both the machine we already have + the ability to grasp itself, but also that won't suffer from being in space where there's both metal welding between bare metals, there's no fluids to be used, and lack of gravity makes things highly complicated vis-a-vis dust that essentially floats about and ether parts of the machine or makes it impossible to work properly. And that's even if you pressurize the asteroid (after digging the first space to enclose the machine). And even assuming you've managed to do all of the above (which is... complicated, an engineering challenge on the orders of magnitude greater than most people get here on earth) then you have to contend with the nature of planetary bodies of the haphazard variety. IE: like i said above, the structure is varied. You may have ice here, loose dust caught there, some metal here, etc. I mean, there's a reason why these things break apart when they're close to the Sun apart from the fact that they melt. Asteroids as ships is a complicated affair that's not worth the effort. You're better off chewing these things bit by bit (spoon to eat the elephant) and make something out of them after you've chopped them apart using methods that don't care much about dust, lack of lubrication etc.

I recently was seeing somewhere (might have been on the antov petrov youtube channel) about a idea of using a thin spherical graphene shell around a standard asteroid and then spinning the asteroid so fast it busts apart and reduced to fine rubble and starts to fly apart, to be caught in the graphene net and ground down... the idea would supposedly allow for maximized hollow spherical interior room and the outside would be almost completely spherical, it would serve as equal and natural radiation shielding in all directions. It would allow easy access to pretty much 100% of the material of the asteroid. It would no longer look like a normal natural asteroid though. You can then either build inside it on the interior wall side, or take easily from the broken pieces of the interior wall and build an object inside it, while the unused remains can still serve as a temporary shielding. This would mean you do not need to drill to hollow it out and grab the materials as you encounter them, but they would all be available from the created shell.

This is a Sibley I've thought a lot about since reading Rin's Star. Concerning habitation, I picture 8 km wide rings inside the asteroid. I think a rotating habitat has to be that wide so the spin doesn't have adverse effects on the life inside. Then they could be configured to spin "against" each other to provide stability. Having that vast amount of resources on hand will allow the miners, colonists, and spacepeople the opportunity to progress. I agree with your progression of mining, to city, to independent colony. The asteroid also provides miles of collision protection.

Orks: Those are some nice Roks.

They arrive at the destination to find that no one is interested in staying put in one star system having lived their whole lives in the void. Which just sounds more pleasant than the passengers turned into cannibalistic space mutants

I got a little question on where my thinking mistake is. The Aldrin Cycler… does it really save any fuel? To dock with the cycler, you need to bring your mass to the same orbital speed, than the cycler is on. So you need the fuel to accelerate and to slow down at your target destination and should be able to make the trip on its own for the same fuel. It doesn‘t give you the shielding, comfort and so on, but for freight, it shouldn‘t make a difference. Am I making a mistake in my reasoning or is fuel not the relevant point with those cyclers? And since I leave a comment on the same day, than your publishing date, I use the chance to thank you so much for your videos.

Problems include: latch onto with what? Materials only have so much strength before they snap. Also: Your anchor is likely to come apart under any significant stress, since you're dealing with asteroids/comets. You can't really strengthen the things; you're not sticking around, and anybody trying has to slow down to do so. If you're sending someone ahead with greater deceleration than you, why not just install a launching laser? Can your ship take the strain? This is a very different sort of stress than that imparted by your engines. Will your tethers hit something important when your anchor goes careening at an unexpected velocity when it comes apart? Also: 'begins slowing?' If you're at a significant fraction of lightspeed, so is your tether, and we're talking about nuclear collisions when your tether hits your proposed anchor. Which doesn't even begin to worry about hitting the dust in the Oort Cloud at relativistic velocities. Pretty sure the best you can do is a gravity slingshot, where you bleed off momentum to a passing gravity source... but that works best with deeper gravity wells.

Don’t know where we going untill we get there.

With the new concept of ''bagging'' asteroids to keep them from flying apart when turning them into spacesteads, [giant rotating space stations] turning asteroids into starships seems not much more complicated than creating spacestead habitats out of them. After all, starships are such habitats, especially since the lengths of interstellar journeys requires crewed spaceships to be flying cities essentially.

A thought, take an asteroid and start it in one of the cycler orbits between two points. It is the truckstop/bus location that was mentioned, but while it is moving, you mine the hell out of it. You could drop supplies off when you are near one of your establishments and use it to build up your 'ship'. It would take a lot of time, but soon you may start running out asteroid to mine. SO you now have a fairly large ship, or lots of little ones, that you just seed into other other asteroids and repeat.

If you combine the use of fusion reactors and self running generators, you'd be set for travel and emergencies. You'd have plenty of energy for many things, including an energy shield.😎

I like the idea of a starship full of yokel cosplayers.

We recently read Ursula K. Le Guin's novella Lost Paradises about the perils of a generation ship. It was meant to be allegorical and a bit preachy / rooted in the time it was written, but I found it to have merit in general in exploring the way life could be on a generation ship (or asteroid), and what could very well happen over a period of generations, rather than indicting one group or another. Don't want to spoil it, just wondering if anyone has read it or listened to it.

Got lost on a 5 minute tangent googling that. Thank you it was worth it.

There was a scientist talking with John Michael Godier recently who came up with a concept that used energy in the solar and galactic wind to accelerate up to significant portions of light speed. I'd imagine that you could scale this up and make it very easy to quickly push a asteroid or massive lump of slag up to some useful fraction of light speed with a rotating habitat behind it or in a recession on the back end, you only really need shielding in front if you're so fast that the penumbra of the stuff you're shielding from is nowhere near your fragile things. It'd be a cheap, fast to get going, dumb, and effective shield against the biggest problems for near light speed ships; dust and radiation. You can use small scout ships or powerful radar to find big things like asteroids and planets far enough ahead to avoid, but there won't be many. If that propulsion mechanism does work then we could have the ability to send out colony ships maybe a century after we get established in the moon, though sourcing supplies from the asteroid belt and the Oort cloud would probably help cheapen that.

"Asteroids do not concern me. I want that ship, not excuses..."

Much of this I've already considered before. Including the asteroid Ganymede. Yet, considered slow rotating elongated asteroids instead. That way they could more easily be divided up to make more individual asteroid ships.

However, to an observer on the spacecraft, he would not notice any changes at all to the spacecraft, because he is on the spacecraft, thus having the same velocity as it. As such, from his point of view the spacecraft's relative velocity is 0, so no length contraction at all, so no stress experienced by the materials On the other hand, to the person on the spacecraft, he would see that the Earth is moving away at relativistic speeds, ond woulh actually see the Earth having a length contraction.
