Every base of Mars should have a communications satellite, otherwise how do we talk with earth? So I built the following model: a communication satellite with an astronaut who can also repair it if necessary, the satellite is connected to solar panels that provide it with electricity and of course it has a computer attached in case it needs to be programmed for additional tasks. The plate of the satellite can rotate 360 degrees and you can turn a signal in any direction you want as well as turn it up or down.
This model can connect to a number of other models I designed under the heading modular mars.
