Magnificent Mars

Guest: Ken Croswell.

Mars is one of the brightest and most beautiful planets—and it may also hold the key to the question of whether life exists elsewhere in the universe. Today on Focus we're joined by astronomer and writer Ken Croswell. His new book Magnificent Mars talks about the geology, topography, and atmosphere of the planet, as well as the spacecraft due to land on its surface within the next few weeks. What do we hope to learn from these latest missions to the Red Planet? This morning, Croswell will be answering that question—and more.
