Description
What most people want to know about Mars is whether there is life on it, but there are other interesting questions to ask about Mars, too, like what makes it red? And what causes its ferocious dust storms? The red planet’s color comes from its iron-rich dust. As for its storms, innocent-looking dust particles warm up in the sun, warm dust meets cold air and creates wind, and soon a storm is taking over the whole planet. Is there life on this dusty red planet? Spacecraft first landed in 1976 and began searching for life. They’ve found promising signs: fossils that look like microbes, and signs that Mars might once have had enough water to sustain life and could still have water underground. Right now, though, the possibility of life on Mars is a question that hasn’t been answered.
