Question: If you wanted to make a planet a place you could live in, what would be vital? What would we have to add/change?
Keywords: colonisation, live, mars, planet
It would appear the planet Kepler, may have potential!
Think of the things we need to survive… oxygen, water, food and shelter. If we could have these things on a planet then we could potentially live there. I think temperature would be something we would need to change, humans are not built to survive extremes of either hot or cold.
This is a really hard question! I wouldn’t make the environment very different from earth. Probably what I would change if I could was some parts of human nature. I think a lot of the problems we see in the world now are down to human factors like greed, selfishness, lack of foresight and a new planet would be better if the inhabitants didn’t have qualities like these.
It would depend what the planet was like, and whether it already had things like water and oxygen. If not, these would be vital, as would be a food source ( plants and animals) as the plant life on a new planet might be toxic to humans. And we’d need material to build homes, and a form of transport to be able to move around.For me personally, it would be nice if my family can come or there is an easy way to visit, as I’d miss them a lot!
I think if humans ever got the opportunity to go live on another planet, that we would learn from the mistakes that have been made on Earth. Hopefully people will think about the effects we have (eg. pollution, environmental destruction) and could plan to try to avoid these and look after what we have, rather than realising too late what has happened. Much like Renee said, it would be nice if we put aside some of the human traits that lead to selfishness and the need for profit in order to live better lives.
We need oxygen, water and some sort of a food supply. That is for a start. Next, we would want a gravity that is close to our own to feel comfortable. Humans are also very fragile. They cannot live below -100C or above 100C, so we might need a weather conditions similar to earth as well.
The term you are describing is call teraforming (see link 1) below). The 1st step of course would be to find a suitable planet, it would be a good idea to start with a planet similar to Earth or at least one which has similar conditions in its solar system. This is called the “Goldilock’s Zone”, ie: not to hot, not cold, but just right (see link 2) below). The next step would be to make sure that it has an atmosphere suitable for us, considering we chose a “just right” planet then we know it could have liquid water so lets assume that it does. Next we should create an oxygen rich atmosphere, this can be done by adding photosynthetic bacteria into any suitable “ocean”. Incidentally, oxygen “rich” means about 20%, the amount of oxygen in Earth’s atmosphere. This would take a loooooooooong time, millions of years. Now that is the most _basic_ things we’d need. We’d also need an active ozone layer to protect us from the new sun’s UV radiation (see link 3) below). Also the planet should have an active magnetosphere to protect us from harmful solar and cosmic radiation (see link 4) below). So basically the planet you choose is _really_ important. How we’d get there is a totally different issue.
