Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil. The main culprit is a relentless stream of particles from the Sun, known as the solar wind. Over billions of years, the solar wind has stripped away […]
