Submission statement (from the article):
>Engineers have designed a spacecraft that could take up to 2,400 people on a one-way trip to Alpha Centauri, the star system closest to our own. The craft, called Chrysalis, could make the 25 trillion mile (40 trillion kilometer) journey in around 400 years, the engineers say in their project brief, meaning many of its potential passengers would only know life on the craft.
>Chrysalis is designed to house several generations of people until it enters the star system, where it could shuttle them to the surface of the planet Proxima Centuri b — an Earth-size exoplanet that is thought to be potentially habitable.
Would that be the B Ark, because I can give you a name of a good captain provided the autopilot is pre programmed.
Interesting concept, I would be curious to an estimation of cost.
It would be a 58km long ship and it has tech we haven’t developed yet, like fusion reactors.
Oumuamua looking thing 🙂
Proxima B is sending us their refugees!
Might as well say we will develop the starship enterprise – warp drives, artificial gravity – unlimited resources… science fantasy
Technically possible now because they discovered how to freeze an embryo from 1994 and still birth a baby from it. So long as the crew was going to colonize in the ship for the 400 years to discover a habitable planet (which they probably won’t)
We’ll call it the Alpha Centauri Initiative and their leader will be called a Pathfinder.
This will be such a good sociological experiment when the whole crew goes mad and tribal and forgets everything about where they came from or where they’re going.
And then we win a technology victory, re-load the save, and restart to do it all over again
Who’s paying for that? Europe? Certainly not NASA.
Hey I was writing a cartoon sitcom about this. I should pick it back up.
what a waste of engineering resources. how about we start with providing clean drinking water for everyone?
Looks like an arts project ? Most of the „experts“ seem to have no expertise at all in this field?
Well you just wait. My proposed ship is going to hold 10,000 people and we’ll be able to go to every exoplanet in the galaxy!
And when they arrive, they what? Die?
Alpha Centauri likely doesn’t contain any habitable planets…
There likely aren’t that many people interested of going – just to die 100-s of years before arrival and leave future generations on an increasingly decaying ship in cramped conditions and with limited supplies.
Imagine the look on the alpha centaurs faces when a derelict ship with 2400 human skeletons shows up in their solar system
We already know Alpha Centauri is likely not human-habitable because binary systems create oblong orbits.
This whole „we need to find a new planet“ craze is just proof that everyone „in the know“ knows we’re all screwed.
There is no „Planet B“ for us – mammals have evolved for millions of years to acclimate to *this* particular spinning rock.
I remember the Sid Meier Alpha Centauri games…I wonder if I would join the University or Morgan
Will they be telephone sanitizers, account executives, and DOGE?
The dust from their remains will enjoy their new home in Alpha Centauri.
400 years without a civil war with humans onboard. I doubt.
“…meaning many of its potential passengers would only know life on the craft.”
Which, sorry WHAT, passenger are they counting that would survive the 400 year journey?
All the people who volunteered to go on this clearly have bought into this project. Their children and future generations may not. Apart from the obvious life supporting requirements like oxygen,food,water, medicine etc future generations may decide they don’t want to do it and turn round or go somewhere else or split into factions and have a war.
If they’re going to design a ship using hypothetical technology, why not power it with anti-matter and get them there in 20 years instead of 400.
They should call it pie. As in ‚Pie in the sky‘
Something like this wouldn’t be built for another 100-200 years
People don’t seem to realise that over that time everything will need replacing. From water taps to air purifiers to hydroponic systems to most systems that provide all water, air, nutrients, food, energy and everything in between. And the systems that maintain these systems need replacing and/or repairing. You need a complete circular economy with less than 0.1% waste per year. We can’t even do that on earth with the most advanced technology. Not even close to only 10% waste after 50 years of trying. Every bucket of piss, every breath of air, every physical body and every shit needs complete recycling without loss for 400 years on this craft. And zero contamination allowed between waste streams with all waste streams near to perfect recovery. And you need the massive factory resources or a unbelievable huge warehouse to maintain every aspect of life. This is clickbait BS, a complete brainfart by people with apparently zero experience in the massive and mostly hidden engineering behind modern society, which doesn’t even come slightly close to what is required here.
**Once we can recycle *everything* our society creates on this planet to 99% recovery, then we can think about stupid pipe dreams like this. In the mean time we need to concentrate on creating a sustainable economy on the only place in the entire universe we can survive on.**
„potentially habitable.“
Seems like the kind of thing we should probably check first. Of course if it’s not… I guess it’s really not our problem.
>The design for a 36 mile long spacecraft, called Chrysalis, includes libraries, tropical forests and structural manufacturing facilities, all supported by artificial gravity.
>This plan is purely hypothetical, as some of the required technology, like commercial nuclear fusion reactors, don’t yet exist.
36 mile long fusion-powered spaceship.
I mean, 2400 is a lot of people, but it’s .0000000000000000001 percent of the human population. Way more than that are born and die every second around the world.
We’re gonna need bigger…
Nobody would be alive on arrival. Even if the ship was perfect and had renewable food-sources, unlimited water through capture/filtration, etc the actually people onboard would kill everybody within a generation or two. Either via accidents, or just via stupidity. We are talking 14-16 generations of people, most of which have never been anywhere but in that ship, in an extremely hostile environment where one accident or unexpected event could kill everyone.
Is this designed to find out what happened to the Alpha Centauri whales?
I know this is all theoretical, but where the heck would they build this 36 mile long craft? In orbit or would they build each smaller module, launch it into orbit and then piece it together?
picture this- just so you know, if our sun is a grain of sand, our nearest star [ alpha centauri ] is 26 miles away.
one of the problems with this, is that during those 400 years. a faster way of traveling through space will have been invented. And then their trip will have been for nothing.
Imagine trying to land on a aome unknown planet with unknown composition, weather, chemical composition and gravity light years away. And having to survive the trip
Isn’t this similar to the end plot point of the movie Don’t Look Up?
I want to know how they plan on recycling bodies.
Because, necessarily, EVERYTHING – every molecule of water and trace chemicals – are going to be of primary value over the next 400 years.
