Mars Habitat

All these ideas looks good and fancy but they are all very expensive and unproven and risky, I think the least risky the cheapest the safest way to establish a base on Mars is to create underground structures, very much like in the movie Star Wars, the desert underground structures, what you do is to dig out the shape of the structure you like, and cloths is with composite panels, in this way you can send a whole back of square panels all in the same size and shape and cloth the walls of the ditch you have drugged with these panels, in this way you have dug a square shaped rooms without losing space and by this this the rooms you are about to create wont weight more than 100 kg or 200 kg of composite panels, whatever it will weight, it will be a fraction of the cost and weight of all these other proposals, and its much safer, so what I would have done is to send a bobcat digger lol with a bunch of composite panels and made a structure that way, and think about it, you can send a whole lot of thin panels in one bach at once to Mars saving space on the spaceship, this is the way to go at first, then when a base is established then you can start thinking about building above the ground, and if I would have a say in it the first above ground structure should have a earth like familiar structure, chose an iconic structure from here and build one of those on Mars, but all these are formalities, to get there you need permission by those who are watching us from above, and not just anyone will have this privilege to set its foot on another planet, its not wild west you know, ask NASA they know the deal.
