Neil DeGrasse Tyson is unquestionably one of the best communicators that the scientific community has at the moment. He is an astronomy wonk and all of his talks on the subject are bursting with enthusiasm and passion for his chosen subject. When it comes to public outreach and inspiring new generations of scientists and science fans, I put him up there with Carl Sagan.

He was recently a guest on the Rationally Speaking podcast with Massimo Pigliucci and Julia Galaf, and he did not disappoint. In the podcast, Neil talks about Obama’s recent NASA announcement, and how it will shape space exploration in the coming decades.

Tyson states that no humans will be going to Mars any time soon. Major expeditions need major, sustained funding and this can only happen if at least one of three fundamental drivers are in place: the glorification of a deity or king, the search for wealth and the need for self-preservation. In essence, power, money and war. None of these driving reasons can currently be used to justify the landing of humans on the Red Planet.

I would note two honorable exceptions to Tyson’s rule: the International Space Station and the Large Hadron Collider. Both projects were monumentally expensive, but nevertheless none of the reasons outlined above were in place. Tyson notes that the end of the Cold War caused the US superconducting collider project to be cancelled in 1989, but this doesn’t explain why the EU persisted with the LHC as the end of the Cold War affected Europe to just as great a degree.

At the end of the podcast, Tyson discusses the recent movie Avatar and some of the movie’s more badly executed concepts. It’s a delightful discussion. I had to laugh when he talked about the creatures with their own USB ports..

This is a top-class podcast from a top-class communicator so if you get a chance, have a listen.
