My space colonists (160 people) are mostly scientists with at least two advanced degrees and some research experience. They all speak English because it is a language of science today. However, the...
I am trying to figure out how to build a human colony on a moon (75% of Earth size) of a gas giant. Some details of the planetary system chosen for colonisation: K-type main sequence star (about...
If I were to attempt the colonization of a planet with preexisting life, how would I manage to pinpoint a candidate planet from the comforts of Earth's orbit? I am interested in the stars somewhere...
I'm picturing an universe where FTL travel was invented as a sort-of-fluke, and artificial gravity technology isn't available. Transit between star-systems takes at least a few days and a star's gr...
What would be the best way to send energy that is generated outside the Earth's atmosphere, possibly in the asteroid belt (nevermind the means), so that it can be used on the surface of the planet?...
I see a lot of media describing large space colonies, and am curious as to how they got there. I'll admit, I'm mostly inspired by Interstellar here. So here's the scenario: A group of 600 settlers...
Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). I found that liquefaction is used to get liquid air and then split it into liquid compounds O2, N2, CO...
So, astronomers discover that ~100 years Earth will be destroyed or rendered uninhabitable by a black hole passing through our Solar System. Governments around the world focus on ensuring Humanity'...
Star A Mass: 1.2 x Sol Radius: 1.157 x Sol Luminosity: 2.074 x Sol Temperature: 6,444 K Star B Mass: 0.63 x Sol Radius 0.691 x Sol Luminosity: 0.158 x Sol Temperature: 4,378 K Semi-Major ...
My question is about a far off and seclusive colony in the reaches of the Orion nebula. As they are relatively isolated they have resorted to harvesting the nebula itself for resources. What I wa...
My current story is set inside a hollowed out dwarf planet (i.e. Ceres) with an artificial gravity generating "mesh" within the shell. This Gravity Mesh can generate a gravitational field that can...
I am writing a story where the main setting is a hollowed out asteroid with an interior biosphere and an exterior city. In this case, using centripetal force to simulate gravity would not work, be...
The time is The Future. Humanity is spreading throughout the stars, aided by the invention of Schwarzschild gates. The gates allow for FTL travel by tearing open wormholes in space. There are thre...
There is a settlement moving along the terminator line on Mercury: I can build it within $\pm 2^{o}$ of the terminator, that is, in the daylight side or the night side. There are going to be lots o...
What technology will humanity use the first time it moves a planet? In the near-ish future, humanity has colonized Mars which has since become self-sustaining and independent, as well as various o...
Would the discovery of alien bacteria found on even an Earth analog planet preclude the possibility of colonization due to the potentially deadly nature of bacterial/viral infections? Put different...
A rocky planet, similar to Earth in mass and composition, is set to pass through the solar system in one year's time. It has frozen oceans of water ice and a thin atmosphere of unknown composition....
In this Answer I came up a scenareo under which Eriek's concept makes sense. I rather like this idea: an expedition or colony on another world has to, for some reason, pull up stakes and move. Th...
My colonists have been terraforming a planet for centuries. They chose this exo-planet for its many earth-like qualities (size, gravity, Goldilocks zone, volcanos, similar sun). However, it is like...
I was told that building a tunnel into the centre of Enceladus is not possible, since it has subsurface ocean and molten, rocky core. But its brother, Mimas is a bit smaller, and shows no sign of ...
If life were discovered in the supposed ocean on Europa, it would be a popular destination for scientists and researchers. I am curious as to what life on Europa would be like, in terms of engineer...
The extreme pressure and temperature greatly reduces our ability to drill holes deeper than some kilometers into Earth's mantle. However, on a body smaller, colder and less dense, this would be a ...
Is it easier to build colonies within the solar system than to send colonies to other stars? Logically, wouldn't we have cities on Pluto sooner than we will have travelled to an exoplanet?
Assuming that the planet is 20 light years away (so back and forth trips would be impractical) we have no clue whether there is any edible life forms on the new planet hibernation (freezing/thaw...
Because of an error in the interpretation of the Mayan calendar I just discovered, I know now that Earth will be destroyed on March 13, 2021 at 11 o'clock in the morning, time zone of Palenque. I ...
I want to build a world populated by humans descended from colonists from Earth who have traveled a long distance and time to arrive (say, 80 years.) They come to this new Earth-like planet in doz...
In a world where three or four, at least, other sentient, intelligent civilisations (of non-human species) with a few planets each exist, earthly humans are getting more advanced. We've finally got...
I'm working on a universe which implies that humanity settled on the Moon. Knowing that we want to keep contact with the Earth (means we don't want to settle on the hidden face) and we want to avo...
There is a really obvious problem with going to a planet we have deemed "habitable". Even if the temperature is perfect, the air composition is perfect and the terrain is perfect we still have the ...
Mars and Earth's moon already feature in a lot of fiction about space colonization. After these two planets, and assuming that other solar systems are too far away, what is the best place within th...
Our planet is dying. Cliche, I know, but unfortunately true and we do not have superpowers or the technology to build generation ships to escape. We have maybe a hundred years left, and we have d...
I've had a look around the internet and the only real classification system for planets seems to be the one from Star Trek, which I don't want to use. The real groups that planets fall under seem t...
One of the big problems by manned space exploration and colonization, that it's insanely expensive. Building a colony on other celestial bodies - since it's impractical to bring back the acquired r...
Was wondering if anyone with physics knowledge could tell me something about desert worlds. If the surface of a planet was mostly a fine sandy material (e.g. Sand) then could tidal forces cause th...
Background: Interest in the red planet is re-surging. For example, Elon Musk has said he will lay out a detailed plan for Mars colonization this September. Question: Assuming the next step in spa...
The first man on the moon was there on July 20th, 1969. After December of 1972, there has not been a person on the moon since. But, what if the missions to the moon had kept on going? By what time ...
Earth is setting up mining colonies on Tau Ceti e. But how can they justify the enormous cost of sending people there? ...Because during the initial exploratory missions, it was discovered that in ...
Supposing you are trying to colonise planet that has no life what-so-ever but is otherwise an earth analogue. First thing that I realised is that there would be no oil. So they would need to make ...
For this question, let's say we have a space faring civilization. They are at least 100 years more advanced than us, and are drawing up plans to send colonists to a neighboring star. The catch is,...
Jupiter is a terrible place to be, but for a number of artistic reasons, I'd like to have my story take place there and only there. "Mining", or resource extraction by any other name, is the usual ...
The year is 2267 A.D. Humanity has colonized Prima Centuari system. A federal government is established; the population is expected to grow at an exponential rate to reach 1 billion by 2300 A.D. A...
How could you create a forest in a space city, like the Citadel of the Mass Effect game? Would this forest provide renewal of oxygen for the population? Is it "simple" to create an atmosphere and ...
Suppose that humanity has spread across the universe, colonizing various habitable worlds, until their empire spans the entire galaxy (or near enough) - but there is no sign of alien life. There ar...
Can you have separate countries in a post-Earth world where humans are colonizing space? I am not talking about physical territory per se, but rather the different identities between separate state...
Let's say Earth's nations meet up and decide to start to colonize space in the next ~50 years. What would the first resources/materials be, that we gather in space/from other planets that we need t...
Far into the future, humanity is largely split into 2 groups. The first group consists of space-dwelling humans, who live in enormous space stations equipped to sustain human life indefinitely, ...
In my other question I tried to find out if it makes any sense to colonize other planets or moons instead of just building space stations. The answer I accepted seems very well elaborated to me and...
I have been poking at the idea of an eventual re-emergence of the PACER concept, where energy is obtained by detonating nuclear explosions... but not exactly in the same form. After humans become s...
My scenario It is 2150, and there are two major human settlements on Mars and a dozen smaller branching-colonies. The colonies, Genesis and Metropolis, founded by Space X and Mars One respectively...
Mars gets somewhat nice In about 1.6 billion years, the sun's habitable zone will have moved outward, increasing the carbon dioxide in Mars's atmosphere. According to Wikipedia, its surface temper...
