How did Pluto meet its largest moon, Charon? Many have speculated that Charon formed in an impact, but traditional models of planetary formation have struggled to explain many of the quirks of this system. This week, Adeene Denton, a research scientist at the University of Arizona, shares her team's new paper that suggests a "kiss-and-capture" may solve this mystery. Then Bruce Betts, The Planetary Society's chief scientist, discusses contact binaries in our Solar System and shares a new Random Space Fact in What's Up.

Space Policy Edition: The Myth of Presidential Leadership 47:05

10 weeks之前47:05

47:05

For over half a century, space advocates and presidents alike have tried to recreate the JFK moment of calling on the country to send a man to Moon — but is this a mistake? The classic book Spaceflight and the Myth of Presidential Leadership argued that it is, and by focusing on presidential power alone advocates set up these initiatives to fail. However, in the decades since its publication, presidential authority has dramatically expanded. In this episode, we examine this tension: Did the success of Apollo create a false expectation about the role of presidential leadership in spaceflight? How can a president most effectively set new long-term goals for NASA?
