This is the Mars Inflatable Station, designed for being built by itself, and ready when human beings reach mars ground.
All the station lands like mars rover did, inside a tetrahedral container, wich has the station and solar panels packed and a working robot.
For first robot will clean the surface from stones and level it.
Then it extends inflatable panels and station, and inflate them with its incorpored pump, getting CO2 from mars atmosphere, wich is slow but affordable. This ground inflatable device would include doors between chambers and halls, and could also haver inflatable furniture, like bed, working table...
Once station is completly open, it inflates with its O2 bottles. Chambers and halls keep its shape with kevlar wires inside, and keep inflated with 1atm pressure air, wich allows to have an aprox 1kg/m^2 density for covering material.
Now station is ready for humans to live in there!!
Labs, kitchen, and other furniture could have been indside packed container or being brought after by humans.
Station is ready to caught CO2 from air, and make O2 with an electrical device for first, and using then one of the external chambers as a greenhouse.
