According to the simulator of circumstellar habitable zone, that only depends on the star properties and distance (what is not the complete picture), the planet Mars
was habitable in the past but not now
is habitable now but not in the future
is not habitable but in 2Gyr when the Sun evolves, it may be habitable
it is wrongly considered to be out of the habitable zone but in reality is in limit of the habitability zone and the habitability conditions are driven by the evolution of the martian climate (atmospheric pressure, temperature, water vapour/ice content)
