Blue Dot: The mysteries of Mars: The Red Planet with author Simon Morden


Blue Dot takes a trip to the Red Dot as Dave talks to British geologist/geophysicist and science fiction writer Simon Morden. In his new book, The Red Planet: A Natural History of Mars, Morden lays out an interesting and accessible guide to what we know about the fourth planet from the Sun after half a century of robotic exploration.

Mars holds many of its secrets close, for example -- where did all its early water come from and where did it go? And of course, the raison d'etre for the Curiosity and Perseverance rover missions is the search for evidence of past or maybe even present microbial life.

Why does Mars have the largest volcanoes in the solar system and a chasm that dwarfs the Grand Canyon? Find out what we know, what we think we know, and what we plain do not understand in this fascinating look at the red planet.

Dave Schlom is the longtime host and creator of Blue Dot. From surfing to Voyager in interstellar space, rock guitar to orcas in our imperiled oceans, the topics on Blue Dot are as varied as the host’s interests and connections -- which are pretty limitless! An internationally respected space history journalist, Dave is also deeply fascinated by all aspects of the grand workings of nature’s awesome machinery on scales ranging from galactic to subatomic. And topics take in all aspects of the arts and sciences.
