Revisiting the discovery of phosphorus on Enceladus
This week on Planetary Radio, we are revisiting one of the biggest recent headlines in planetary science, the detection of Phosphorus in the oceans of Saturn’s moon Enceladus. Phosphorus is a key ingredient for life on Earth, and this discovery marks the first time it has been found in an ocean off of Earth. Chris Glein, a lead scientist at the Southwest Research Institute, joins us to discuss the discovery and its implications for the search for life. Then Bruce Betts returns for What's Up.

An astrogeologic experience with Kirby Runyon
Sometimes, when you want to learn more about other worlds, all you have to do is step out your door. Mat Kaplan, Planetary Radio's creator and former host, takes us on an adventure with planetary geologist Kirby Runyon as they tour New Mexico, U.S.'s varied geology and compare it to other worlds. They'll explore the dunes of White Sands National Park, the Mars-like geology of Kilbourne Hole, and the rocks in the Carrizozo Lava flow. Then Bruce Betts, the chief scientist of The Planetary Society, and host Sarah Al-Ahmed discuss the most otherworldly places they've been in this week's What's Up.

Space Policy Edition: Was the Space Shuttle a policy failure?
Was the Space Shuttle a successful program? In many ways, yes: it endured for 30 years, launched hundreds of astronauts into space, and built the International Space Station. But, according to the goals of lower costs, rapid reusability, and reliability NASA stated at its conception, the Space Shuttle program was a failure. In this new recurring feature on SPE, Jack and Casey read through a classic paper in space policy and discuss its arguments, its conclusions, and whether the paper stands up to this day. Read along with us and suggest future episodes in our Planetary Society online member community.
