Overall however establishing a habitat on Antarctica is vastly easier than on Mars, assuming we won't be able to source complex materials in situ or fabricate for at least 50 yr. The atmospheric pressure, atmospheric composition and water availability being the main advantages. If the snowfall is particularly intense solar power might be troublesome, but it's still vastly easier to settle. Proof: we reached the south pole in 1911 and have a station there since 1956.
