Mars does have an atmosphere, it just isn't able to support us. The atmosphere there is thin and mainly CO2 - something that I find interesting is that as a result of the CO2 atmosphere, massive glaciers of dry ice form over the poles in the winter. One of the probes we sent we landed near one of the poles and fully expected to be flattened by said glaciers.
