It was a terrible, tragic week for commercial space development. Historian and space policy analyst John Logsdon helps up understand the greater meaning of the SpaceShipTwo and Antares disasters on this special edition of Planetary Radio, with additional thoughts from Bill Nye. Emily Lakdawalla shares better news from around the solar system, and the new movie about interstellar travel plays a role in this week’s What’s Up with Bruce Betts.
