Dava Newman

Deputy Administrator for NASA

It was a grand night at the Pasadena Civic Auditorium. CEO Bill Nye led the Planetary Society’s 35th anniversary party with guests including Neil deGrasse Tyson and Deputy NASA Administrator Dava Newman. We present a very brief sampling of the celebration. Also, Emily Lakdawalla talks maps, while Jason Davis and Casey Dreier report on the planning workshop that has begun the process of deciding where humans will someday land on Mars. A barbershop quartet introduces Bruce Betts’ Random Space Fact on What’s Up.
