Very well explained! I love science and astronomy and space!

So where does all this grey rock color come from, and is it consistent throughout all the explored regions?

3D printing from light to matter is possible...Imagine whole planet like playground of 3D printing or replicating the Earth. Which chemicals or which laser beam or any kind of energy pulse put on ground and watch rocks shaping into metals (iron for example) and EMG shield like that on Earth...math should calculate rotation and power of that field according to mass of the Mars.

Mars atmosphere is 95% carbon dioxide and Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide. Our atmosphere also contains water vapor, traces of dust particles, pollen, plant grains and other solid particles. Yet the skies look exactly the same? Come on!
