Come with us on a visit to the home of the prime meridian for a conversation with the curator of the Royal Observatory, Greenwich about the race to create a practical means for determining longitude. It’s a dramatic story of precision astronomy and clock making, told by the Curator of the Observatory to Mat Kaplan as they examined the timepieces that helped revolutionize navigation. Bill Nye is on vacation, but we’re joined by Emily Lakdawalla with hazy news from Pluto, and Bruce Betts' explanation of the plutonium that just passed its namesake planet.
This week's prizes are a fabulous Planetary Radio t-shirt and a beautiful new LightSail patch.
This week's question:
If you were a car company trying to market the Apollo mission Lunar Roving Vehicle, what would you name it, and what would your slogan be? There is no right answer. Answers will be judged based on humor and/or effectiveness or whatever other criteria we feel like.
