Because it is farther away from the Sun than Earth, Mars is very cold. Sunlight and heat reaching the Red Planet is a lot less than what Earth gets. Also, the Martian atmosphere is not as thick as Earth’s atmosphere, which keeps our planet warm. Consider what it would be like to stand near Mars’ equator, where sunlight hits more directly than at higher latitudes. At noon, that would feel like a cold winter day in the northern United States (32 oF). At night, that same spot could reach temperatures of -284 oF, which is four times colder than Antarctica. Living in Mars will require special habitats that can provide warm temperatures (and breathable air).
