What can you infer about the results of numerical models in 1966 for polar caps made of water ice?

Those people could sustain on Mars, by living closer to the poles

Explanation:

As it is given that caps involve the water ice instead of the carbon dioxide

And, current observations of spectrum analyzed that the polar caps are totally different from one other i.e northern one involves more water ice while on the other hand,  the southern one involves most of the carbon dioxide

Moreover, the astronomers unable to see to spectrum portions as the atmosphere absorbs the wavelength

So we conclude that the people could survive on mars if they live near to poles
