Chris was a brilliant interviewee but, needless to say, only snippets ended up in the broadcast programme. Here is more of the interview. Particularly interesting are his thoughts on why humans should go to Mars - it's not for science fundamentally, he argues, but for questions about human destiny.
Just down the corridor from Chris, we later interviewed Jennifer Heldmann who studies both the Moon and Mars.

All the evidence points them being created in the here and now. There could be one being carved as you read this.
Listen to Jen tell Kevin about the gullies, the possibility of deep aquifers on Mars and where she would choose to visit if SpaceX gave her ticket for their forthcoming 'Mars for the Average Person' package.
Just beyond the Ames security perimeter is the Mars Institute, where planetary scientist Pascal Lee works in his Mars image-bedecked office.

I have to include an extra picture of a man who brings his dog to work with him. Why aren't all employers as enlightened as the Mars Institute?

In this interview, Pascal also describes some of the research which the Mars Institute and NASA do on the dry, desolate Devon Island in the high Arctic. Centred on a great meteorite impact crater, this is the Haughton-Mars Project, aimed at preparing for human missions to Mars, sometime - God knows when - in the future.
