Episode 31 --- Interstellar Propulsion --- What We Need to Make Star Trek Real

Propulsion physicist Marc Millis talks about the prospects for fast, efficient interstellar travel.  Millis was head of NASA’s Breakthrough Propulsion Program at Glenn Research Center outside Cleveland for years beginning in the mid-1990s.  We discuss why the problem of traveling to the stars is so difficult and what would need to happen to help such dreams become a reality.  It’s a lively and irreverent discussion!
