It started with a question from a listener. The answer comes from Dawn mission chief engineer and mission director Marc Rayman. Marc also tells us about his new job as chief engineer for mission operations and science at NASA’s Jet Propulsion Laboratory, and shares his love of space exploration with Mat. LightSail 2 is still going strong! Program manager Bruce Betts opens this week’s What’s Up segment with a mission status report.

The ion engine-powered Dawn spacecraft will orbit Ceres for many years. Could it have touched down on the surface of the dwarf planet?

Why didn’t Dawn land on dwarf planet Ceres?

This week on Planetary Radio, we explore "The Lost Universe," NASA's first tabletop role-playing game, with Christina Mitchell, a senior multimedia specialist at NASA's Goddard Space Flight Center in Maryland, U.S.A. Then, we'll shift our gaze from the mythical to the methodical with Amaury Triaud, an astronomer from the University of Birmingham in the U.K. He and his colleagues have found a new method for potentially detecting liquid water on the surfaces of terrestrial exoplanets. We close out with our chief scientist, Bruce Betts, for What's Up and a new random space fact.

Sometimes, misunderstandings can spark beautiful adventures. This week on Planetary Radio, we explore the story behind the naming of Zoozve, a quasi-moon of Venus, with Latif Nasser, co-host of Radiolab. He shares how a typo on a space poster led the Radiolab team on an epic quest to convince the International Astronomical Union to name this quirky space object. Then, Bruce Betts, our chief scientist, pops in for What's Up and a discussion of some of the things asteroid hunters have found lurking in our Solar System.

Former NASA Administrator Mike Griffin joins the Space Policy Edition to discuss his notable 2007 speech outlining the tension between so-called “real” and “acceptable” reasons for space exploration.

“Acceptable” reasons for space exploration are logical, policy-friendly justifications such as workforce development, technology spinoffs, and STEM engagement. They are quantifiable and dispassionate — the Vulcans of arguments.

However, Griffin argues that the essence of humanity's drive to explore space is the “real” reasons, which are intuitive, emotional, and grand. They have value but are hard to quantify. These include the innate human desire for competitiveness, curiosity, and the urge to leave lasting legacies through monumental achievements. 

Why do we have this dichotomy? What in the system itself prefers acceptable reasons over real reasons? And how can we leverage the relative strengths of both systems to be better space advocates?

Former NASA Administrator Mike Griffin discusses his claim that there is a tension between the so-called Real reasons that motivate spaceflight and the prosaic, Acceptable reasons used to justify space exploration within the public sphere.
