Wandering Universe

Episode 17 of Wandering Universe.  Since there are a slew of planets visible I thought I'd revisit and slightly revise a short tour of the planets that I wrote back when I began not this podcast but my old one, "What's Up This Week".  This is part one of two episodes covering Mercury through Mars.  I also talk a bit about the "Planet Nine" news and a little about the recent near-miss of SpaceX's Falcon 9 rocket.
