Lasses + lads, is some group of people working on a way of making self-sustaining space ships that can be home to the several generations of colonists needed to make the journey?
I want huemans going to Earth 2.

Also, is terraforming a meme, or is it viable?

Kepler-22b is a meme compared to other possible Earth analogues. Just look at how big it is.

The distances involved are so enormous that a ship launched today would be overtaken by a ship launched 50 years later.

In 100 years we will have better engines and better telescopes determining if that planet is a boiling water planet lacking landmasses.

A perpetually self sustaining environmental system is tricky, look at Biosphere II in Arizona, there are a lot of sensitive variables, and if you forget certain parts then your web can't knit itself together. I think you'd want to use something organic rather than mechanical wherever possible just because if you take care of it, it's designed for self maintenance.
With more biotech you could make colonies of bacteria and life forms that eat and process organic waste and scrub the air.
I'd be in a bigger hurry to figure out how to keep orbital colonies viable while we're still inside the system first.
By then there should have been many more galactic planetary surveys with better telescopes, methods, and analysis, and even telescopes and instruments capable of directly imaging exoplanets, even using spectroscopy to figure out what it's atmosphere is made of.
It would suck to rush off too soon on a generational voyage, only for technology back home to have developed enough to figure out that the system doesn't have anything close to habitability.

There is a habitable planet in the nearest star next to Earth just 4.2 light years away. With our current technology using a mixture of Fission engines and laser guided acceleration we could actually send a spaceship full of people there within 20 years.

>it has been found that this planet is subjected to powerful radiation activity from its parent star every 100 days, much more violent storms than the stellar flares emitted by the Sun and which would be capable of sterilizing life on Earth.

>Researchers at the University of Warwick say that Kepler-438b is not habitable due to the large amount of radiation it receives. The question of what makes a planet habitable is much more complex than having a planet located at the right distance from its host star so that water can be liquid on its surface: various geophysical and geodynamical aspects, the radiation, and the host stars plasma environment can influence the evolution of planets and life, if it originated. The planet is more likely to resemble a larger and cooler version of Venus.

Living on planets is a meme. Humanity puts so much energy into getting stuff out of a gravity well, why would you ever want to return to it?

Advanced species don't live on planets, instead they deconstruct all the planets for raw materials and build artificial habitats or a dyson swarm, most likely both at the same time.

Remember that we only live on the surface of planet Earth. The surface area could be 100,000x as big if we used the Earth's mass to build artificial habitats. It just doesn't make sense to live on planets. Humanity is NEVER going to colonize another planet. Instead we'll slowly transition towards space habitats of which the international space station is an example.

You guys were whining "why waste money on the ISS go to Mars for fucks sake" not knowing that NASA actually made the right decision and ignoring red herrings like Mars to instead focus on what's really important: Learning how humans can live in artificial habitats since that is our long-term future.

Breakthrough starshot
You could build a ring of installations around the sun that just collect solar energy to power MASERs on interstellar light ships.
The only problem with that is if you don't have a sister installation at the other end you're going to blow through the system so fast you'd barely have time to take pictures.

Sure here you go my dude.

https://en.wikipedia.org/wiki/Project_Daedalus

which propulses the spaceship with 12% the speed of light.

Using the starshot laser system you can accelerate the spaceship up to 20% the speed of light. Using

https://en.wikipedia.org/wiki/Breakthrough_Starshot

Using these 2 methods at the same time might accelerate the spaceship somewhere between 25-30% the speed of light (Doesn't scale linearly).

However due to having to decelerate without lasers it would still take 20 years to reach them instead of just the 15 years the top speed would suggest.

Note that the starshot program was specifically set up to reach that planet.

[Anonymous No.10529944]

>>10529927
Yeah exactly. Which is why you would also install a fission propulsion system to slow yourself down before entering the orbit of the planet. We will probably only see this happening when we are old men though as I don't see this project being launched in the next couple of decades.

It would be far less massive than an entire colony full of people hoping the brakes don't fail.
The less mass the fast you can accelerate.
If your probes can replicate themselves and travel to other nearby systems and repeat the process you could have an entire transit system waiting for you, a literal wagon train to the stars.
You've also pretty much established an stellar empire

Because it's something innate we haven't really been able to do for years. Unless you count Jews building settlements in Palestine or hippie communes in rural parts of the Pacific Northwest.

Wouldn't the bombs destroy the ship once you blew them up?

[Anonymous No.10530410]

>>10530320
No, you're blowing them up behind you in big bells with a lead bumper plate with shock absorbers to keep your ship from being shaken apart.
Also once you're in space there isn't any atmosphere to propagate a pressure wave that does most of the damage when you drop nuclear bombs. Whats pushing you along through space with an orion drive is the pressure of the energy being created deflected behind you.

[Anonymous No.10530414]

How do they know the bumper plate won't break?

That'd be a nightmare to be in a craft that would never be able to slow down.

You just turn the ship around and start accelerating in the opposite direction.

That would also cut your maximum velocity in half though.

Also if you've destroyed your pusher plate, you no longer have the means to accelerate.

>That would also cut your maximum velocity in half though.
This is the real world, and not star wars. If you're going to another star then you have to reach the escape velocity of the sun and the solar system, which means unless you plan on slowing down at the other end you're probably still going to be traveling at the escape velocity of the destination star.

Easier to slow down a robot ship than a manned one at least since it won't have to carry any life support equipment. Would be a great application for an NSWR or NPPR too since your robot ship is a lot more tolerant of radiation than a manned ship could be.
