This was one of the highlights of this summer’s James Randi Educational Foundation Amazing Meeting 9. It’s a panel discussing our future in space and, in particular, whether humans should continue exploring in person or stay on the ground while our technological marvels do the dangerous job of traveling beyond Earth gravity.

The panelists were Bill Nye (The Science Guy), astrobiologist Neil deGrasse Tyson, astronomer Pamela Gay, and cosmologist Lawrence Krauss, with Phil Plait moderating. As you’ll see, the conversation turned pretty intense at a few points, and it was fascinating to see such smart people debating what our space program should do next. This runs almost an hour, but is well worth your time.
