 The Star Spot Episode 104: The Great Terraforming Mars Debate: The Dream, with Chuck Black | File Type: audio/mpeg | Duration: 39:35

Feature Guest: Chuck Black Ever consider moving to Mars? The Star Spot did. Along with the University of Toronto Astronomy and Space Exploration Society, we co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. The great terraforming Mars debate.  We were joined by a 5 member panel of experts, representing a wide range of backgrounds. We approached the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now over the course of 4 episodes I’m being joined at The Star Spot by each of our guests from that event. We covered the science of Mars with planetary scientist Paul Delaney. We then turned questions of Martian and Earthling biology with Dr. Olathe MacIntyre. Finally, switching gears, we asked NASA’s planetary protection officer John Rummel if we should terraform a lifeless world. These have been weighty discussions so in this fourth and final interview with journalist Chuck Black of Canadian Aerospace News we’re going to have a little fun. We’re going to dream of our loftiest vision of a Martian colony and we’re going to ask, if we do opt for colonization, how would we choose who to send as ambassadors of our species. Current in Space   About Our Guest Chuck Black is a journalist, technology advocate, public speaker and activist. He edits and contributes articles to the Commercial Space blog, the Canadian Aerospace News, and the Space Conference News.

 The Star Spot Episode 103: The Great Terraforming Mars Debate: The Ethics, with John Rummel | File Type: audio/mpeg | Duration: 37:15

Feature Guest: John Rummel Ever consider moving to Mars? The Star Spot did. Along with the University of Toronto Astronomy and Space Exploration Society, we co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. The great terraforming Mars debate. We were joined by a 5 member panel of experts, representing a wide range of backgrounds. We approached the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now over the course of 4 episodes I’m being joined at The Star Spot by each of our guests from that event. We covered the science of Mars with planetary scientist Paul Delaney. We then turned questions of Martian and Earthling biology with Dr. Olathe MacIntyre. Now it’s time to switch gears. Even if we could make Mars habitable, we must confront the equally profound question, should we do it? If Mars already habours life, even just microbes, does that make terraforming off limits? If Mars has dormant life, should we reawaken it? And do humans have an imperative to spread life to the barren worlds of our solar system and beyond? To tackle these biggest of questions today we’re joined at The Star Spot by Professor John Rummel of NASA’s Planetary Protection Subcommittee. Current in Space What’s the best way to study the largest volcano in the solar system? Anuj explains. And while every major galaxy has a supermassive black hole at its centre, have you ever wondered just where do they come from? Tony sheds some light.

 Episode 102: The Great Terraforming Mars Debate - Part 2: The Biology, with Olathe MacIntyre | File Type: audio/mpeg | Duration: 35:53

Feature Guest: Olathe MacIntyre Ever consider moving to Mars? The Star Spot recently did. Along with the University of Toronto Astronomy and Space Exploration Society, we recently co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. Can we terraform Mars to make it habitable? And if we can, should we? We were joined by a 5 member panel of experts, representing a wide range of backgrounds in order to approach the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now over the course of 4 episodes we're joined at The Star Spot by each of our guests from that event. We started, appropriately, with the red planet itself. In our last episode planetary scientist Paul Delaney updated us with the most current understanding of the characteristics of Mars pertinent to the planet’s suitability for life. Today we look at the biology, turning the focus on us, that is, the biota of Earth. We’ll be asking what we need to change about Mars to make it friendlier to our kind of life? What techniques are available toward that end? And could Earth life itself play a key role in transforming the red planet? Current in Space Did you know dung beetles use the Milky Way galaxy for navigation. Don't believe us? Anuj will explain how it works. Then Tony shares how supermassive black holes may unlock the secrets of distant galaxies.  About Our Guest Dr. Olathe MacIntyre received a B.Sc. in Biology at Dalhousie University.  After working as an Onboard Marine Biologist in Alaska, she completed her M.Sc. in Space Science at the International Space University in France, and co-authored “Visysphere Mars: Terraforming Meets Engineered Life Adaption.” She received an internship at the world-class Controlled Environment Systems Research Facility at the University of Guelph, where she earned a Ph.D. in Environmental Sciences.

 Episode 101: The Great Terraforming Mars Debate - Part 1: The Science, with Paul Delaney | File Type: audio/mpeg | Duration: 39:36

Feature Guest: Paul Delaney Ever consider moving to Mars? The Star Spot recently did. Along with the University of Toronto Astronomy and Space Exploration Society, we recently co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. Can we terraform Mars to make it habitable? And if we can, should we? We were joined by a 5 member panel of experts, representing a wide range of backgrounds in order to approach the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now, over the next 4 episodes I’ll be joined at The Star Spot by each of our guests from that event. We start with the science. For the debate over terraforming Mars depends in large part on the attributes of the red planet, on whether it harbours life, and on what technologies are possible to make the planet suitable for a human settlement and even civilization.
