Ah, Mars. The red planet. A planet of extremes. During the day, it's scorchingly hot. At night, it's so cold that carbon dioxide freezes into blocks on the ground. In between, the sublimation of the carbon dioxide causes blasting winds, whipping sand everywhere, scouring the landscape. These are all conditions that explorers will have to account for should they venture to Mars. We already have the technology to compensate for many discomforts and dangers. There's really any number of options. But first, we need to get there.
