The biggest difference between the Mars-
When all that is achieved one is in a position to explore and research. Then a person keeps having pleasure in exploration and will probably be more inventive. Like our European ancestors who never returned when they immigrated to e.g. Australia. They first secured their wellbeing before going to have another adventure.
Before I'll give an example how to create an Earth-
Outside their protected environment people need to wear pressurized suits and air bottles. Mars conditions are not much more convenient than those on our moon.
Let me try to explain how to create an Earth-
Then the second option, how I built the pond, is to create a 'bath' of rubber sheets and a thermal insulation blanket under it. The most suitable option for Mars, as long as we don't know the structure of its soil and the materials that are available to make something water and/or air-
My concept below is the lightest construction and least voluminous in materials you need to take with you from Earth. Volume and weight are our enemies on these long trips to other planets. Like air pressure, or the lack of it, is our enemy on Mars. The reason why everything needs to be made air-
See the draft of my concept here below:
The main structure (F, D & C) is the aluminum 'gray' positioned on Mars surface. Encircled is an aluminum angled plate (D) of about 6 cm. thickness and 1.80 meter length by 1.20 meter width with two hinged parts (C) moving out to the left. This structure should be covered by rocks and soil (E) and as such pressing the aluminum structure to the direction of Mars surface. Pressure towards Mars surface is needed because the inside pressure from the direction of B is 0.8 atmosphere (bar) against a Mars pressure on the flexi glass A of only 0.01 bar.
The purposes of the aluminum structure (D & F) are to create a frame for the flexi glass windows (A) on top and to prevent these windows flying away due to the higher pressure (B) below.
Glasses (A) should be double glassed or better less breakable double flexi glassed, separating and isolating the cold Mars temperatures from the relatively hot temperatures inside 'Jimmy's-
Most of the structure is well protected against radiation under ground level or under a hill of soil. I do realize this draft, as any, may not be instantly clear to everyone. More detailed I'll explain it on the next page. The first Jimmy-
The roof structure of aluminum and flexi glass need to be brought from Earth. Only slightly more volume is needed for the rubber sheets covering the below Mars surface excavation where trees or whatever will grow. These additional rubber rolled-
