Terraforming Mars: Modeling engineered aerosols to warm the planet
Whenever humans arrive on Mars, they're going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere is very thin and almost all carbon dioxide; and all the water is frozen and mixed with ice made of CO2. Oh, and solar radiation will be hazardous on Mars' surface since the planet has no ozone layer to block ultraviolet radiation, especially so during solar flares. Disneyland it is not.
