Solar Panels?

Since only half of the solar energy that reaches Earth reaches Mars, solar panels aren't the best idea. There would not be enough sun to obtain a sustainable and usable amount of energy from only solar panels. They could be incorporated, but not our only source of energy. Instead, our colony has decided to add only a few solar panels on the highest points of the land(mountains, hills), this way they can absorb the most energy they can. Our primary source of energy will come from Wind Turbines. This will be our best source of energy because there is a great amount of atmospheric dust, so we will always have usable energy available to our colony.

Gravity?

With only a third of Earth's gravity available on Mars, plants would not be able to grow properly due to gravitropism. This would stop the plants from being able to sustain the biogeochemical cycles and the colony wouldn't be able to survive. Plants need to be able to absorb water and nutrients properly, but with only a third of the Earth's gravity, the colony had to come together to create a solution so that gravitropism could occur. It's important that the plants grow upright and the roots grow into the ground. After a long discussion, the colony decided to bring gravity stimulaters, and implant them into the ground. The stimulaters will regulate the gravity on Mars and cause it to mimic the gravity on Earth.

Frozen Polar Ice Caps?

Since Mars contains large quantities of water under the surface, a large group of people would travel to Mars first and break down the surface above the water to melt the ice caps. We'd return back to Earth for a long period of time, to allow the Ice to melt. When enough time has passed, we would bring everyone from the colony back to Mars and the Polar Ice Caps would have turn into bodies of water such as oceans, rivers, and lakes. The hydrological cycle would have already begun, and water would be cycling through evaporation and transpiration, and precipitation.

Soil on Mars?

In order for the colony to grow crops, we need to have greenhouses where we grow them. The soil on Mars is too corrosive, so instead we're using hydroponics. In order for the hydroponics to work and be able to regulate cycles like the sulfur, nitrogen, and phosphorus cycle, we needed to bring things for the cycles to work. A great amount of decomposers would be brought to Mars, and many of them would be added to the water so that decomposers can add nutrients to the water, which the plants will then absorb and a cycle can start. We will also bring things like rocks that contain iron sulfide and phosphate, so that there's a source for the sulfur and phosphorus cycle inside the greenhouse if these are put into the water. We would plant lots of legumes, this way there is always a supply of nitrates for the nitrogen cycle. We would also bring nutrient-rich soil from Earth to Mar's, so that we could have other producers growing in areas other than a greenhouse. This would also require decomposers and legumes so that a cycle could continue outside of a greenhouse. The sulfur cycle would occur because their will be sulphate in the atmosphere from factories. We would add phophate ions into the bodies of water so that slow-cycling of phosphate could occur. The Carbon/Oxygen cycle, would occur naturally because of photosynthesis and cellular respiration which would happen in plants and in the humans coming to Mars, but only if there is energy from the sun present. The water cycle would naturally occur with the changes in weather.

Can We Live

on Mars?

If we look around at the Earth we have created, we definitely have not treated it the way that it should be treated. We are ruining everything we touch, take advantage of our resources, are greedy with how much we use, and don't look at our consequences on the environment. We don't know how to take care of the Earth and its resources yet. If we can't take care of our own planet, how are we expected to take care of a new one? The idea of a fresh start isn't ideal; we'll just being starting out with a new environment, but we would still be treating it the same. We need to learn how to work on fixing our own planet, before we can even begin to start looking at a new one.

Life on Mars!

Enhanced Greenhouse Effect?

Mars only consists on 95% oxygen. In order to change this, we will have many, many plants, all photosynthesizing and creating more oxygen on Mars. Since we have things like factories, there will be lots of greenhouse gases released as we will be burning lots of fossil fuels in those factories. We will also bring cars, to release more gases more quickly, that way we can also increase the temperature of Mars in the process by creating an enhanced greenhouse effect with all of these gases being released into the atmosphere and ozone. This effect is necessary because plants need more sun to photosynthesize, and as humans, our bodies would not be used to the temperature and atmosphere on Mars, so an enhanced greenhouse effect would be necessary for our colony to flourish.

The consequences of creating an enhanced greenhouse effect is that we don't know how the atmosphere around Mars will react. The atmosphere may be very sensitive, and we could create a hole in the ozone layer immediately. It could also be a very tough atmosphere, and an enhanced greenhouse effect could take years to make any changes. How the atmosphere reacts to the greenhouse effect will decide how successful our colony will be on Mars.
