Modular Mobile Mars base

initial mobile mars intitial base, i wish i had more free time... to make some more attachments,refinements and some descent renders but this 'll have to do i'm afraid

I can imagine when ariving on mars there's no cranes, or lifting equipment available unless brought. Thats why i opted for a mobile initial settlement where the easy to transport cylinder is dropped on the planet.
then the Modules can be coupled/2 minimum, inflate the tires and drive to a meeting point where all modules can be coupled together for an initial stationary base. If the need arises (storm, radiation,...)they can be decoupled and move to another location without much hastle.

2 or more linked modules could drive off to set up an outpost aswell.

the modules are have a universal tool coupling to attach robotic arms, excavator, drill,antena,... this also neutralises the need for multiple other vehicles.
On top there are protective hatches that can cover the integrated solar panels in severe dust
