From monkeys, to turtles, to dogs, and more (for better or worse) humans have used animals to test different aspects of space travel since its earliest days. This week, Dean and Anna discuss some of those missions along with the their pitches for what signs of life we are most likely to potentially discover within our own solar system as well as what they hope we might find some day. We are also joined by Head Keeper at the Cincinnati Zoo & Botanical Gardens, Cody Sowers to discuss their recent decision to name their latest baby penguins Mars and Rover, as well as other tie ins between zoo keeping and astronomy.
