Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

Edwin Grosvenor writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada.

Submersed begins with an investigation into the beguiling subculture of DIY submersible obsessives: men and women—but mostly men—who are so compelled to sink into the deep sea that they become amateur backyard submarine-builders. Matthew Gavin Frank explores the origins of the human compulsion to sink to depth, from the diving bells of Aristotle and Alexander the Great to the Confederate H. L. Hunley, which became the first submersible to sink an enemy warship before itself being sunk during the Civil War.

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

Most observers would agree that we have to turn away from harming our planetary home, and one another, if coming generations are to have any chance of surviving and thriving. They say we have to abandon the path of cruelty, neglect and physical harm to others, and seek out the path of harmlessness towards all living things and especially towards all the peoples on this earth. Simply put, we must learn to share.Planetary Conversations with Dr. Warren Bell is a podcast that explores this idea through in-depth interviews with guests who, one way or another, have taken steps towards improving life...
