#66 Saturn’s largest moon Titan is an incredible place, but could anything live there? Canadian Astrobiologist Dr Catherine Neish led a study on Titan’s habitability. She joins us for a fascinating chat about what she found.
Titan. The largest moon in the Saturnian system has been a candidate as a habitable world ever since NASA’s Cassini mission sent back the first radar images of its surface in 2004. Astrobiologist Dr. Catherine Neish of Western University in Canada has spent years studying Titan, and has just published a study on the habitability of Titan.

#63 Space Ethics. How do we navigate the ethical challenges of our journey beyond Earth?
So we pollute the upper atmosphere with rocket exhaust, is it worth the benefits of communications satellites and GPS? What about space junk? the garbage of earth orbit. Or mining asteroids? who owns the asteroids, can should they be able to sell the minerals asteroids provide?
These are questions that would never have been asked before space travel became as regular as it has today. Let's take a look at this new way of thinking about our responsibilities in space.
