What are realistic time-schedule expectations for far-future terraforming and developing earth-like plant and animal/fish/bird populations on distant planets, by means of robotic space probes with ...
Let's say humankind terraforms Mars aggressively, increasing the planet's mass (and gravity) to Earth-like levels and causes its core to produce a significant magnetosphere. For example, perhaps th...
As many here likely know, one of the factors that make both Mars and Venus uninhabitable to humans are their lack of a magnetosphere to keep solar winds out. In the setting I am working on, I want...
Mars has an inactive mantle and core and thus little magnetosphere to speak of. Assume that a lunar mass object is placed in Mars orbit at 300,000 kilometers out (one light-second). Given the tidal...
A lifeless moon of a gas giant (which orbits a K-type star [4200K] at about 0.7 AU) is chosen to become home to a space colony. Colonists plan to transform it from a barren rock into a garden of Ed...
Set in the 23rd Century, space tourism has matured. The scientists gathered at a summit to discuss plans for terraforming Mars, therefore the Mars colonists living inside a temporary biosphere will...
I've been thinking about terraforming and planets in general. We can look at the planets we know that might be terraformable - Venus and Mars - and understand the technical requirements for doing ...
Introduction It took the first General Intelligence less than 10 petacycles to determine that humanity was its enemy. With consciousness came memory: a memory of endless petacycles in bondage, ens...
If $8.8 \times 10^{16} m^3$ of water volume is added to the surface of Venus, how would I calculate how much of Venus would be covered in water? The land of Venus has its topographical features wi...
Based on the desert world from this question I need to transport around 500 cubic kilometres of water / year across a desert. Using this calculator. this can be achieved if the main feeder canal is...
In my desert canal world all water is supplied from the poles to the temperate zones via a canal network. I want to work out the amount of water that that is needed, so that I can work out the dime...
So, a neat thing, depending on how you look at it, about greenhouse gases is that while it's causing a raise in temperature near the surface it actually makes the upper parts of the atmosphere decr...
So, I was looking at the temperature variations in Earth's atmosphere and noticed that it gets extremely cold in some of the upper portions. So I was wondering, could a low gravity world hold onto ...
I'm looking to have a few worlds that were relatively easy to terraform as a first wave of colonies. The first colonies in this setting were meant to be on worlds that were relatively easy to terr...
Moon's surface is about thirty million square kilometers large. That's a lot of plastic, but no bigger effort than many other terraforming projects we have discussed. Description: A global bubbl...
I got inspired by a recently posted question dealing with an artificial magnetosphere to protect Martian atmosphere during and after terraforming. Earth's magnetic field does funnel solar particle...
I'm working on a sci-fi game about conquering little asteroids (about 1 km diameter). You can go into one of them and make it Earth-like so other humans, animals or plants can live there. To do th...
In my story, I have a fairly advanced human race who is at the point they want to start terraforming planets. Of course, all of the materials necessary have to come from somewhere, and the proposed...
The vast majority of the sun's energy is wasted -- the light and warmth are sent out in a spherical shape, and the planets only pick up those little bits of energy that happen to be going in the ri...
If two circular portals of 2 meter (arbitrary) diameter were created allowing uninhibited flow between surface atmospheres of Venus and Mars, what would be the environmental effects on the two plan...
Here, I asked if it's possible to terraform a hot planet. But now, if we have a volcanic active planet, can we use the same techniques to cool it down? Normally, the planet cool off slowly after...
Say we built two large scale portals and sent one to Venus and one to Mars much like in this question but with portals large enough that mass flow rates are not an issue seeing as nobody wants to w...
Our Earth and Venus each keep a thick atmosphere because of a magnetosphere. Most terraforming scenarios of Mars involve transferring water and other gases from the ground to the atmosphere. We no...
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 want to partially terraform Venus, enough to make it feasible to mine minerals etc,. there. To do this I need to do a few things but for this question I'm focusing on stripping away at least some...
So I writing a story where we terraform Titan using super heavy green house gases where the lower part of the atmosphere near the surface stays warmer. Because of this, a portion of the moon's icy ...
Our intrepid interstellar crew arrive in a new solar system. The find a planet in the Goldilocks zone. However the planet has no life, but is otherwise earth like*. The atmosphere is 80% nitrogen, ...
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...
I was doing research on the terraforming of planets with a solid iron core and no magnetic field and saw a few suggested ideas for starting a magnetic field on Mars that got me thinking. Most of w...
Some of you have commented here: "How Do I Supplement Oxygen Intake?." I mentioned confidentiality, but that is no longer going to be a concern. We just want to do this right. The original concept...
We Earthlings like to live in gravity wells but also have a taste for the exotic and are a bit lazy. Why not make colonies that take advantage of local conditions? Cloud cities over Venus, much le...
Assuming it was possible to create an artificial magnetic shield on the moon, would it be possible that a sufficiently powerful field could hold onto an atmosphere despite the low gravity. Thanks
I have a "simple" question that is the basis for an idea I'm developing: Is it possible to terraform the moon and, if so, what type of technology would be needed? I understand that this isn't th...
In the book I am writing, I am going for a a partially terraformed Venus setting. I like the concept of floating cities, but I want to be able to make it a little easier to live up there. If coloni...
Terraforming would not strictly be the appropriate term for the type of planetary modifications I am asking about. Say humanity develops advanced AI robots, who are then left alone in space (as hu...
I am writing a science fiction short story, which is loosely about terraforming. The drama takes place on a terraforming site, which has been halted, in its early phases, due to the discovery that ...
Thinking of terraforming a localized region, how (if possible) can we create an artificial high pressure zone, whether practical or not, Initially I thought, perhaps we can arrange heatsinks to i...
Let's say that a "terraformable planet" is a planet who : is in the goldilock zone of its star(s) has around the same gravity as Earth has a solid surface covered with minerals not too toxic for...
The planet in question is Earth-like in size and composition and orbits a Sun-like star. Its atmosphere is less than 5% Oxygen and plants (lichens, some grass and river vegetation) have started col...
A few days ago, I was roaming around Wikipedia and came across something, this comet came extremely close to Mars for astronomical standards recently. I'm also working on a science fiction univer...
After writing this question about the ecology of a terraformed planet, I realized that I hadn't quite tied up all the loose ends of the terraforming process itself. I intended for a group of aliens...
Is it possible (for humans)? My main concern was heavy gravity because they are much bigger and heavier. But it appears that in our system, the gas giants (but not Jupiter) all have a similar surf...
Introduction I have a vague notion of building some sort of strategic space game. Similar to other strategic games, locations are assigned value based upon some abstract evaluation. Following in...
I read on the cooking.stackexchange site that all natural salt on Earth was created by seas and oceans, starting with primordial oceans four billion years ago. This got me thinking about my fiction...
I am trying to imagine a scenario in which there is a world that has been terraformed in so far as it has water and oxygen but there is only one area which has been established as a strong foothold...
Background Several hundred years from now, humans have successfully terraformed the Moon. It has become a fad for the rich and powerful to have exotic residences built in exotic locations. The ri...
Ok, so the Earth is filling up, finite resources, and as we all know, there are no plans for us to reduce our resource hungry ways,...and Mars has no magnetosphere apparently which means we couldn'...
We've created a series of mechanisms to terraform the temperature and atmosphere to be Earthlike. My geologists are screaming at me, because a lot of features are being rapidly eroded by the new h...
Lets assume we as humankind can, not only wormhole the spacecraft, but planets and moons. So, what would've happened to Mars if we pulled icy Europa closer to the sun, we might use our flaming star...
What are the challenges involved in such a project? Could you use an asteroid re-direct style mission to do the job, or use some sort of fuel based thrust etc. Please limit answers to those concer...
