Lack of oxygen, we need to take plant to provide oxygen for us

# data[].attributes.body
There is no air so you will need to convert CO2 to O2

# data[].attributes.body
Diamond,

# data[].attributes.body
Some materials needed are going to be oxygen, and construction materials effective for using in Mars. (Make sure there is a normal gravity)

# data[].attributes.body
We would need advanced tecnology, a big amount of money and plants that give us oxygen.

# data[].attributes.body
Some challenges will be the amout of money, tecnology, oxigen

# data[].attributes.body
Water, Dirt, Oxyge, coats.

# data[].attributes.body
Mars doesn't have water and oxygen, which are basic things we need. We would need to find a way in which we can produce oxygen and have a source of water.

# data[].attributes.body
I think the most needed material will be oxygen and a water

# data[].attributes.body
Materials are expensive and some are limited (Lack of)

# data[].attributes.body
some materials in theory I think would had a different reaction at Mars

# data[].attributes.body
We need oxygen and water which are fundamental for humans, additionally, rockets, special suits.

# data[].attributes.body
Rockets, fuel

# data[].attributes.body
There are no resources of water, we need to adapt it with some kind of water reserve.

# data[].attributes.body
Fuel, electicity

# data[].attributes.body
A expensive material can be fuel

# data[].attributes.body
Fuel

# data[].attributes.body
Water, oil, food

# data[].attributes.body
very hard to do and is a very resisitant material

# data[].attributes.body
Fuel, materials for transportation,

# data[].attributes.body
californium

# data[].attributes.body
Materials such as fuel will be expensive because we will need a lot of it.

# data[].attributes.body
We would need to have rockets that fly at the speed of light. Or rockets that have crio sleep for the people who are traveling, because mars is very very far away, and space can cause many negative effects on our body if we are exposed to not gravety for a long time. We will need a big water plant because that is difficult to find in mars and we need that to live. We would need some kind of suit that helps regulate our corporal temperature.

# data[].attributes.body
Scientists create californium by bombarding curium with alpha particles. This reaction creates the radioactive chemical element with an atomic number of 98.

There are currently ten known isotopes known to exist.

It can help treat certain forms of cancer, detecting gold and silver in ores and residual oil within nearly depleted reservoirs. It can only be created artificially on Earth but is speculated to be made in supernovae.

No wonder it is so expensive.

# data[].attributes.body
Material to build a dome in which the temperature is habitable and has a water system. Also we would need a lot of rockets to get to mars.

# data[].attributes.body
Gasoline, water, oxygen, Soil

# data[].attributes.body
Because of the lack of oxygen we would need plants

# data[].attributes.body
petrolium , water , fertile lands

# data[].attributes.body
You need a heating and cold system

# data[].attributes.body
Pieces to create a good and equipped rocket, fuel.

# data[].attributes.body
Certain material are expensive because they are limited since the lack of resorses.

# data[].attributes.body
Transportation of all the people, and the use os special suits. Infrastructures and functioning mechanisms.

# data[].attributes.body
These materials are expensive because they are hard to find, hard to make, and maybe expensive to send to Mars.

# data[].attributes.body
Aerogel, apart from being very light, does not conduct heat. The cost 110

# data[].attributes.body
Materials are expensive because they are scarce and made of expensive elements.

# data[].attributes.body
Most valuable materials for the future:
- water
-plants
-oxygen
-Fuel

# data[].attributes.body
They are very expensive because they are specifically created for something that is out of the ordinary.

# data[].attributes.body
The Fuel, The petroleum

# data[].attributes.body
Water

# data[].attributes.body
Oil and fuels

# data[].attributes.body
Water, electrizzity, air

# data[].attributes.body
There are expensive materials because there are difficult to make

# data[].attributes.body
Fuel, something so people could trnasport, oil and some equipments.

# data[].attributes.body
They are expensive since they are materials which are hard to find and they are difficult to transport to mars.

# data[].attributes.body
Because the cost of the production of the material and the process

# data[].attributes.body
Expensive materials are the ones that are hard to find, make and transport. Like fuel. Like gold, uranium, oil etc.

# data[].attributes.body
water, air

# data[].attributes.body
Water, Food, life like the plants.

# data[].attributes.body
Air, water, etc.

# data[].attributes.body
Because they are some materials that are har to make and they would need a lot of money to move from one place to another. So the materials would be cost a lot.

# data[].attributes.body
Water, oxygen, mining materials

# data[].attributes.body
We would need:
1. Air
2. Water
3. Plants

# data[].attributes.body
Because they are hard to find, they are hard to transport, and hard to make.

# data[].attributes.body
Water, oil

# data[].attributes.body
Lot of oxygen and lot of water

# data[].attributes.body
Diamond

# data[].attributes.body
Some matirrials are very expensive because are shortag of it

# data[].attributes.body
Water, gasoline and wood

# data[].attributes.body
water, food and oil
